RESUMEN

INTRODUCTION: The urinary bladder undergoes morphological and functional changes in patients with symptomatic benign prostatic enlargement (BPE). These detrusor changes reflect chronically increased intravesical pressure as a result of outlet obstruction. This study aims to determine the relationship between the Pre- and Post-op detrusor wall thickness (DWT), international prostate symptom score (IPSS), and duration of lower urinary tract symptoms (LUTS) in patients who had open simple prostatectomy (OSP). METHOD: This was a prospective study of a cohort of patients who had OSP for symptomatic BPE. The IPSS and symptom duration for each patient were noted. Each patient also had an abdominal ultrasound scan with a measurement of their DWT. Retropubic OSP was done for each patient. The detrusor wall thickness was also measured 12 weeks after the prostatectomy. RESULTS: Fifty-two patients completed the study; the mean age was 66.37 ± 8.09 years. The median pre-operative IPSS was 28 (IQR = 13.75), and the median duration of symptoms was 24 months (IQR = 37 months). The mean pre-operative DWT was 4.41 ± 1.38mm, while the mean post-operative DWT was 2.16 ± 0.98mm. The preoperative IPSS (p = 0.833) and duration of symptoms (p = 0.375) did not significantly correlate with the pre-operative DWT. There was a significant reduction in the mean DWT (p < 0.001) and IPSS (p < 0.001) following prostatectomy. CONCLUSION: DWT appears not to be significantly influenced by the severity or duration of LUTS. However, it reduced significantly following OSP with corresponding improvement in urinary symptoms.

INTRODUCTION: La vessie subit des changements morphologiques et fonctionnels chez les patients présentant une hyperplasie bénigne de la prostate (HBP) symptomatique. Ces modifications du détrusor reflètent une pression intravésicale chroniquement augmentée en raison de l'obstruction de la sortie. Cette étude vise à déterminer la relation entre l'épaisseur de la paroi du détrusor (EPD) avant et après l'opération, le score international des symptômes prostatiques (IPSS) et la durée des symptômes des voies urinaires inférieures (LUTS) chez les patients ayant subi une prostatectomie simple ouverte (OSP). MÉTHODE: Il s'agissait d'une étude prospective d'une cohorte de patients ayant subi une OSP pour une HBP symptomatique. L'IPSS et la durée des symptômes pour chaque patient ont été notés. Chaque patient a également subi une échographie abdominale avec mesure de leur EPD. Une OSP rétropubienne a été réalisée pour chaque patient. L'épaisseur de la paroi du détrusor a également été mesurée 12 semaines après la prostatectomie. RÉSULTATS: Cinquante-deux patients ont terminé l'étude ; l'âge moyen était de 66,37 ± 8,09 ans. L'IPSS médian préopératoire était de 28 (IQR = 13,75), et la durée médiane des symptômes était de 24 mois (IQR = 37 mois). L'EPD moyenne préopératoire était de 4,41 ± 1,38 mm, tandis que l'EPD moyenne postopératoire était de 2,16 ± 0,98 mm. L'IPSS préopératoire (p = 0,833) et la durée des symptômes (p = 0,375) n'ont pas significativement corrélé avec l'EPD préopératoire. Il y a eu une réduction significative de l'EPD moyenne (p < 0,001) et de l'IPSS (p < 0,001) après la prostatectomie. CONCLUSION: L'EPD ne semble pas être significativement influencée par la gravité ou la durée des LUTS. Cependant, elle a considérablement diminué après l'OSP avec une amélioration correspondante des symptômes urinaires. MOTS-CLÉS: Hyperplasie bénigne de la prostate, Épaisseur de la paroi du détrusor, Score international des symptômes prostatiques, Prostatectomie simple ouverte.

RESUMEN

Background: Male stress urinary incontinence (SUI) after surgical treatment of benign prostatic enlargement (BPE) is an infrequent but dreadful complication and constitutes a therapeutic challenge. The efficacy and safety of the adjustable trans-obturator male system (ATOMS®) in these patients is rather unknown, mainly due to the rarity of this condition. We aimed to assess the results of ATOMS to treat SUI after transurethral resection (TURP) or holmium laser enucleation (HoLEP) of the prostate. Methods: Retrospective multicenter study evaluating patients with SUI after TURP or HoLEP for BPE primarily treated with silicone-covered scrotal port (SSP) ATOMS implants in ten different institutions in Europe and Canada between 2018 and 2022. Inclusion criteria were pure SUI for >1 year after endoscopic treatment for BPE and informed consent to receive an ATOMS. The primary endpoint of the study was a dry rate (pad test ≤ 20 mL/day after adjustment). The secondary endpoints were: the total continence rate (no pads and no leakage), complication rate (Clavien-Dindo classification) and self-perceived satisfaction (Patient Global Impression of Improvement (PGI-I) scale 1 to 3). Descriptive analytics, Wilcoxon's rank sum test and Fisher's exact test were performed. Results: A total of 40 consecutive patients fulfilled the inclusion criteria, 23 following TURP and 17 HoLEP. After ATOMS adjustment, 32 (80%) patients were dry (78.3% TURP and 82.4% HoLEP; p = 1) and total continence was achieved in 18 (45%) patients (43.5% TURP and 47% HoLEP; p = 0.82). The median pad test was at a 500 (IQR 300) mL baseline (648 (IQR 650) TURP and 500 (IQR 340) HoLEP; p = 0.62) and 20 (IQR 89) mL (40 (IQR 90) RTUP and 10 (IQR 89) HoLEP; p = 0.56) after adjustment. Satisfaction (PGI-I ≤ 3) was reported in 37 (92.5%) patients (95.6% TURP and 88.2% HoLEP; p = 0.5). There were no significant differences between patients treated with TURP or HoLEP regarding the patient age, radiotherapy and number of adjustments needed. After 32.5 (IQR 30.5) months, median follow-up postoperative complications occurred in seven (17.5%) cases (two grade I and five grade II; three after TURP and four HoLEP) and two devices were removed (5%, both HoLEP). Conclusions: ATOMS is an efficacious and safe alternative to treat SUI due to sphincteric damage produced by endoscopic surgery for BPE, both TURP and HoLEP. Future studies with a larger number of patients may identify predictive factors that would allow better patient selection for ATOMS in this scenario.

RESUMEN

INTRODUCTION: Despite advancements in the treatment of benign prostatic hyperplasia (BPH), the mechanisms underlying BPH development and progression remain elusive and lacks a one-size-fits-all therapeutic solution. Prostatic inflammation contributes to BPH and lower urinary tract symptoms (LUTS), but the initial trigger remains unknown. Current research suggests dysbiosis of the urinary microbiome as a potential culprit. This systematic review explores the emerging field of the male urinary and prostatic microbiome and its relationship with BPH/LUTS. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. A systematic search in the Pubmed and Scopus databases was performed using specific terms. Inclusion criteria considered male non-neurogenic patients with LUTS due to BPH with analyses of urinary microbiome, concerning evaluation of English-language publications with relevance. RESULTS: Among seven articles involving 542 patients, there was an association between male LUTS/BPH and the urinary microbiome. Findings indicate a correlation between urinary microbiome dysbiosis and LUTS severity, with specific bacterial genera such as Streptococcus and Haemophilus linked to higher International Prostate Symptom Score (IPSS) scores and PSA levels. The fecal microbiome may be associated with LUTS, although contradictory findings are reported. The review also highlights methodological inconsistencies, small sample sizes, few negative controls and a lack of comprehensive clinical data as major limitations. CONCLUSIONS: While there is an undeniable correlation between the microbiome and LUTS/BPH, future research should aim to standardize sampling techniques and expand the score to include functional microbiome characterization, potentially leading to novel, microbiome-targeted therapeutic strategies for BPH.

RESUMEN

INTRODUCTION: Benign prostatic enlargement (BPE) and lower urinary tract symptoms present challenges in aging men, often addressed through transurethral resection of the prostate (TURP). Despite technological advancements, bladder neck contracture (BNC) remains a concern. This study explores predictors, including comorbidities, influencing BNC after TURP. METHODS: A retrospective cohort study at Changhua Christian Hospital analyzed 2041 BPE patients undergoing bipolar TURP. Preoperative urinary catheterization and resection speed were categorized. Patient data included demographics, comorbidities, operative details, and outcomes. Statistical analyses utilized χ2, Kruskal-Wallis tests, and Cox regression models. RESULTS: Within 3 years, 306 (15%) patients developed BNC. Univariate Cox regression identified chronic heart failure (p = 0.033), chronic obstructive pulmonary disease (COPD; p = 0.002), preoperative urinary catheterization (p < 0.001), and low resection speed (p = 0.045) as significant BNC risk factors. Notably, COPD (p = 0.011) and preoperative urinary catheterization (p < 0.001) emerged as independent risk factors for BNC development in multivariate Cox regression analysis. CONCLUSIONS: Preoperative urinary catheterization and COPD were significant predictors of BNC post-TURP, while resection speed showed no significant influence. These findings offer clinicians insights for risk assessment, enhancing patient outcomes, and optimizing resources post-TURP.

RESUMEN

Context: Dutasteride is used in the treatment of benign prostate enlargement with reported many side effects. Aims: The purpose of this study is to examine how different doses of dutasteride (0.5 mg) in combination with tamsulosin affect the outcome of treatment of benign prostatic enlargement (BPE). Settings and Design: Prospective study (phase III trial). Subjects and Methods: Between April 2017 and March 2020, this randomized study was conducted on 300 patients with moderate-to-severe lower urinary tract symptoms attributable to BPE and a prostate volume of more than 40 cc. The patients were divided into three therapy groups at random (one-to-one randomization), each with 100 patients: (Group I) daily tamsulosin 0.4 mg plus dutasteride (0.5 mg). (Group II) every other day tamsulosin 0.4 mg plus dutasteride 0.5 mg. (Group III) once a week tamsulosin 0.4 mg plus dutasteride 0.5 mg. Statistical Analysis: Statistical analysis was carried out with the help of the SPSS program 22. (IBM, Armonk, NY, USA). The mean and standard deviation (SD) are used to express quantitative data (SD). When comparing two means, an independent-samples t-test of significance was used. To compare more than two means, a one-way analysis of variance was utilized. For multiple comparisons between distinct variables, a post hoc test was performed. Results: Patients were followed up every 3 months, with a 1-year follow-up to examine the medications' efficacy, prostate size reduction, and erectile function. After 1 year of treatment, all groups showed significant improvement in their symptom scores. However, Groups I and II experienced a considerable reduction in prostate size after therapy, but Group III experienced no meaningful reduction. In terms of sexual dysfunction, there was a considerable shift in Group I after 12 months. Conclusions: Dutasteride treatment on the other day schedule has the same efficacy as the daily dose on prostate size at the same time; the other day scheduled dose has better preservation of sexual function.

RESUMEN

Context: Worldwide, urological disorders vary from one topography to another. An in-depth understanding of their distribution in each region could serve as a basis for the distribution of manpower, equipment's alongside determine policy formulation and training. Aims: This study enumerates the annual frequency and distribution of urological disorders at the Federal Medical Centre, Keffi. Settings and Design: A cross-sectional retrospective study from November 2021 to November 2022 of all new patients who attended the urology outpatient clinic, emergency department as well as those who had surgical interventions at the Federal Medical Centre, Keffi, Nasarawa State. Materials and Methods: The pertinent records were extracted from the patient's electronic medical records (EMR) and entered into a semistructured questionnaire. Statistical Analysis Used: Data were analyzed using the SPSS software version 20. Results: A total of 452 new patients were seen over the study period. There were 428 (94.5%) males and 24 (5.3%) females, with a male-to-female ratio of 17.8:1. The median age was 58 years, with the age range of 2-97 years. Urological emergencies were seen in 13.5% patients. Ninety-eight percent of cases were acquired, whereas 1.8% were of congenital etiology. Overall, the most commonly diagnosed urologic diseases among new patients in order of decreasing frequency were benign prostatic enlargement (BPE) (54.7%), urethral stricture disease (11.0%), upper tract urinary calculi (6.3%), prostate adenocarcinoma (5.9%), and male infertility (4.3%). Conclusions: BPE, urethral stricture disease, upper tract urinary calculi, prostate adenocarcinoma, and male infertility are common in our environment. An understanding of the urological disease distribution will enhance policy-making and drive manpower needs inspiring core areas of subspecialization with a view at improving the standard of urological care and promoting collaboration with international organizations and funding agencies.

RESUMEN

OBJECTIVES: This study investigated the effects of prostate surgery on storage symptoms in male patients with lower urinary tract symptoms (LUTS) from benign prostatic enlargement (BPE). This study aimed to identify patient characteristics associated with improved, unchanged, and deteriorated post-surgical storage symptoms and to identify the risk factors for non-improvement or deterioration. METHODS: A retrospective analysis of 586 prostate surgeries performed between 2016 and 2022 at Yokosuka Kyosai Hospital was conducted on patients with LUTS and at least one storage symptom preoperatively. Patients with active urinary tract infection, prostate/bladder cancer, urethral strictures, or dementia were excluded. The study enrolled 230 patients and assessed storage symptoms using the International Prostate Symptom Score (IPSS). RESULTS: Overall, storage symptoms improved, remained unchanged, and deteriorated in 87.0%, 5.7%, and 7.4% of patients, respectively. The patients in the deteriorated group were significantly older, whereas those in the no-change group had smaller prostate volumes. Patient-reported outcome scores (IPSS, IPSS-QoL, and BII) were significantly higher in the improved group. The predictors of non-improvement included low IPSS storage score, cardiovascular disease, and diabetes mellitus. Predictors of deterioration included advanced age and low IPSS storage score. CONCLUSIONS: Patients with severe LUTS showed greater postoperative improvement in storage symptoms. A low IPSS storage score predicted non-improvement and deterioration. Advanced age, low IPSS storage score, and a history of cardiovascular disease and diabetes mellitus were identified as key predictors. Awareness of these factors may guide preoperative counseling and improve decision-making in prostate surgery, ensuring more personalized and effective treatment strategies.

RESUMEN

INTRODUCTION: Traction on the per-urethral catheter is commonly employed after monopolar transurethral resection of the prostate (mTURP) to reduce bleeding. However, its efficacy and impact on postoperative pain remain uncertain. Further, there is limited evidence to suggest any benefit regarding post-operative blood loss. MATERIALS AND METHODS: In a randomized controlled trial, 62 patients undergoing mTURP were assigned to either a traction (n = 30) or non-traction (n = 32) group. Blood loss, postoperative pain, and analgesic requirements were assessed between January 2022 and April 2023. {(IHEC-PGR/2021/DM/M.Ch/Jan/02), CTRI Registration: CTRI/2022/01/039199.}. RESULTS: No significant differences were observed between the traction and non-traction groups regarding postoperative blood loss (p-value- 0.632), fall in hemoglobin (p-value- 0.719) and hematocrit (p-value- 0.937) levels, and length of postoperative hospital stay (p-value- 0.797). However, the traction group reported significantly higher postoperative pain scores (p-value < 0.001) and increased analgesic requirements (p-value < 0.001). CONCLUSION: The study suggests that 12-hours catheter traction after mTURP does not reduce blood loss and is associated with increased postoperative pain.

RESUMEN

PURPOSE: Adreno-muscarinic synergy, a supra-additional contractile response to simultaneous application of α-adrenoreceptor and muscarinic receptor agonists, is a feature of several lower urinary tract regions that have dual sympathetic and parasympathetic innervation. We tested the hypothesis that synergy is also a feature of prostate tissue obtained from men with benign prostatic enlargement. METHODS: Isolated tissue strips were dissected from prostate 'chips', collected after transurethral prostate resection procedures for in vitro experiments, to measure isometric tension at 36°C. RESULTS: Added separately to the superfusate, phenylephrine and carbachol generated contractions with mean pEC50 (-log10EC50) values of 5.36 and 5.58, respectively, although phenylephrine maximal responses were about six-fold greater. In the presence of carbachol, the mean phenylephrine pEC50 was significantly increased to 5.84 and maximal response increased by 28%; overall, a significant synergistic response was demonstrated. The synergistic response was reduced by muscarinic receptor antagonists, most potently by the M3-selective agent 4-DAMP (1,1-dimethyl-4-diphenylacetoxypiperidinium iodide), and less so by M2 and M1-selective inhibitors gallamine and pirenzepine, but with an overall profile indicating M3/M2 mediation of the synergistic response. The magnitude of the synergistic response was variable between prostate chips that provided isolated preparations suggesting regional heterogenicity, although their zonal origin could not be determined. CONCLUSION: These experiments show that adreno-muscarinic contractile synergy is a feature of human hyperplastic prostate tissue. This has implications for the use of a combination therapy of α-blockers and anti-muscarinic agent to relieve secondary symptoms associated with benign prostatic hyperplasia, at least in men who can tolerate antimuscarinics without a risk of retention.

RESUMEN

PURPOSE: To compare the efficacy and the safety of Tamsulosin 0.4 mg/day and 0.8 mg/day in patients suffering from lower urinary tract symptoms due to benign prostatic obstruction. PATIENTS AND METHODS: A prospective interventional, double-blinded, controlled study was carried out on 93 patients who met the criteria and divided randomly into two groups: group A for Tamsulosin 0.4 mg/day and group B for Tamsulosin 0.8 mg/day. International prostate symptom score, post void residual urine volume, and maximum flow rate of urine were assessed before and after 4 weeks of treatment. RESULTS: Both study groups showed a significant reduction in storage sub-score but only frequency was significantly reduced in group B (P < 0.001). On the other hand, Tamsulosin 0.8 mg was superior to Tamsulosin 0.4 mg regarding voiding sub-score except for straining (P = 0.325). Accordingly, the total international prostate symptom score was significantly improved in group B versus group A (P < 0.001). Furthermore, maximum flow rate and post-void residual urine volume were notably improved in Group B as compared to Group A (P < 0.001). Of all adverse events only dizziness was noted to be statistically significant in Group B versus Group A (P < 0.001). CONCLUSION: Tamsulosin 0.8 mg has shown better outcomes in treating patients who suffer from lower urinary tract symptoms due to benign prostatic enlargement than Tamsulosin 0.4 mg, and besides that, it is well tolerated. TRIAL REGISTRATION NUMBER: M S 292/2020, SID: 373, date: 22/4/2020.

RESUMEN

Introduction: Benign prostatic enlargement (BPE) and type 2 diabetes mellitus (T2DM) are common in elderly men. This study aimed to correlate the Doppler resistive indices of prostatic arteries with the severity of lower urinary tract symptoms (LUTS) and prostate volume in men with concomitant BPE and T2DM. Material and methods: Fifty men with T2DM and BPE (BPE-DM) as cases and 50 age-matched men with BPE but no T2DM (BPE-ND) as controls were enrolled. B-mode and power Doppler ultrasonography of the prostate gland were done for both groups. Results: The mean total prostatic volume of the BPE-DM was 79.18 ±8.9 ml, while that of BPE-ND was 60.73 ±10.6 ml (p <0.0001). The mean prostatic resistive index (PRI) was significantly higher among BPE-DM than BPE-ND (0.74 ±0.02 vs 0.68 ±0.09 for right capsular artery; 0.77 ±0.04 vs 0.71 ±0.02 for left capsular artery; and 0.76 ±0.04 vs 0.70 ±0.02 for the urethral artery). BPE-DM with higher glycated haemoglobin, fasting plasma glucose, and longer duration of T2DM experienced more severe lower urinary tract symptoms and had higher PRI. Conclusions: In conclusion, the BPE-DM group presented larger prostate glands and more bothersome LUTS, which correlated with higher PRI. Strict glycaemic control is necessary in men with co-existing BPE and T2DM.

RESUMEN

AIMS: Benign prostatic enlargement (BPE) can impact lower urinary tract function due to its potential progression to benign prostatic obstruction (BPO). Treatment options include removal of the obstruction by surgery or through use of therapeutics designed to slow growth or reduce tissue stress imposed by muscular stromal components. Inflammation and development of fibrosis can also raise intrinsic tissue stress within the gland, further impacting obstruction. Outflow tract obstruction can also impact emission and ejaculation if the obstruction persists. METHODS: This review summarizes an ICI-RS think tank considering novel drug treatments that might address BPO caused by progressive development of BPE, as well as manage decompensation changes to bladder function. RESULTS: Topics included recent advances in our understanding of pathological changes occurring to the prostate and other lower urinary tract tissues during progressive development of BPE, and how prevention or reversal might benefit from the identification of novel drug targets. These included contractile properties of prostatic tissues, the impact of BPE and its effects on bladder function, the deposition of intramural fibrotic tissue with protracted BPO, the role of inflammation in the development of BPE and its progression to BPO. In particular, we discussed current therapeutic options for treating BPE/BPO, and new therapeutic targets, what they treat and their advantage over current medications. CONCLUSION: Several new drug targets were identified, including soluble guanylate cyclase (sGC), the receptor for nitric oxide (NO•), and sGC activators that promotes sGC-mediated cGMP production when sGC is inactivated and unresponsive to NO•.

RESUMEN

BACKGROUND: Haemorrhage is a common complication following open simple prostatectomy and patients may sometimes require a blood transfusion. Tranexamic acid has been shown to reduce blood loss following transurethral resection of the prostate and open radical prostatectomy. This study evaluated the effect of perioperative intravenous administration of tranexamic acid on blood loss and blood transfusion rates in patients who had OSP for benign prostatic enlargement. METHODOLOGY: This was a comparative study of patients with documented prostate glands 60g and above scheduled for OSP. Initial hematocrit was done a day before surgery. The patients were randomized into a tranexamic acid group, which received perioperative intravenous tranexamic acid and the no-TXA group which received placebo (0.9% saline). All patients had open simple retropubic prostatectomy. Final post-operative hematocrit was assessed 72 hours after surgery, and blood loss was calculated using the modified Gross formula (actual blood loss = estimated blood volume x change in hematocrit / mean hematocrit). The transfusion rate was documented. RESULTS: Fifty-six patients participated in this study and were randomized into a tranexamic acid group and no-tranexamic acid group. The mean age of patients in the tranexamic acid group was 66.07 ±7.08 years and was comparable to the no- tranexamic acid group which was 66.50 ± 8.80 years (P = 0.842). The median total blood loss was lower in the tranexamic acid group (502mls, IQR 613) compared to the no-tranexamic acid group (801mls, IQR 1069). The difference in the median blood loss between the two groups was 299mls (U 275, P 0.055). The rate of blood transfusion was lower in the tranexamic acid group (6 patients, 21%) compared to the no tranexamic acid group (11 patients, 39%), (P = 0.146). There was no difference in complication rates between the two groups. CONCLUSION: The use of tranexamic acid in patients undergoing open simple prostatectomy showed a trend towards reduced intraoperative blood loss and less need no tranexamic for blood transfusion. This is of clinical significance, especially in elderly patients with low cardiovascular reserve.

CONTEXTE: L'hémorragie est une complication courante après une prostatectomie simple ouverte et les patients doivent parfois recevoir une transfusion sanguine. Il a été démontré que l'acide tranexamique réduit la perte de sang après une résection transurétrale de la prostate et une prostatectomie radicale ouverte. Cette étude a évalué l'effet de l'administration intraveineuse périopératoire d'acide tranexamique sur les pertes sanguines et les taux de transfusion sanguine chez des patients ayant subi une PSO pour hypertrophie bénigne de la prostate. MÉTHODOLOGIE: Il s'agissait d'une étude comparative de patients dont la prostate de 60 g et plus était documentée et qui devaient subir une PSO. L'hématocrite de base a été effectué un jour avant la chirurgie. Les patients ont été répartis aléatoirement dans le groupe acide tranexamique, qui a reçu de l'acide tranexamique periopératoire par voie intraveineuse, et dans le groupe sans TXA, qui a reçu un placebo. Tous les patients ont subi une prostatectomie rétropubienne simple ouverte. L'hématocrite postopératoire a été évalué, et la perte de sang calculée à l'aide de la formule de Gross modifiée. Le taux de transfusion a été documenté. RÉSULTATS: Cinquante-six patients ont participé à cette étude et ont été randomisés entre le groupe avec acide tranexamique et le groupe sans acide tranexamique. L'âge moyen des patients du groupe acide tranexamique était de 66,07 ±7,08 ans et était comparable à celui du groupe sans acide tranexamique qui était de 66,50 ± 8,80 ans (P =0,842). La perte sanguine totale médiane était plus faible dans le groupe avec acide tranexamique (502 ml, IQR 613) que dans le groupe sans acide tranexamique (801 ml, IQR 1069). La différence de la perte de sang médiane entre les deux groupes était de 299 ml (U 275, P 0,055). Le taux de transfusion sanguine était inférieur dans le groupe acide tranexamique (6 patients, 21%) par rapport au groupe sans acide tranexamique (11 patients, 39%), (P =0,146). Il n'y avait pas de différence dans les taux de complication entre les deux groupes. CONCLUSION: L'utilisation de l'acide tranexamique chez les patients subissant une prostatectomie simple ouverte a montré une tendance à la réduction de la perte de sang peropératoire et un besoin moindre de transfusion sanguine.

RESUMEN

Background: The etiology of benign prostatic hyperplasia (BPH) is still elusive. The aim of this study was to provide preventive and prognostic parameters associated with diabetes mellitus with benign prostatic enlargement (BPE). Methods: Diabetic patients were collected retrospectively from February 2021 to December 2022, including monocyte-to-lymphocyte ratio (MLR). Diabetic patients were divided into two groups by whether the prostate volume was greater than or equal to 30 ml, which were diabetes mellitus without BPE (DM) and diabetes mellitus with BPE (DM+BPE). The baseline characteristics were compared, the risk and protective factors associated with DM+BPE were determined using univariate and multivariate logistic regression, and the parameters associated with prostate volume were determined using correlation analysis. Results: Of the 671 patients collected, age and prostate volume were significantly higher in the DM+BPE than in the DM; MLR was higher in the DM+BPE than in the DM; and platelet was significantly lower in the DM+BPE than in the DM. Univariate logistic regression showed that age was a risk factor, while protective factors for DM+BPE were lymphocytes and platelet. Multifactorial logistic regression showed that age was a risk factor, while platelet was the protective factor for DM+BPE. In the total overall (n=671), prostate volume was positively correlated with age. Prostate volume was negatively correlated with lymphocytes and platelet. In DM+BPE (n=142), prostate volume was positively correlated with age and MLR. Conclusion: Platelet was a protective factor for DM+BPE and was negatively correlated with prostate volume, whereas MLR was positively correlated with prostate volume in DM+BPE.

RESUMEN

BACKGROUND: Depression is a common condition that may lead to suicide at its worst. It is considered one of the primary causes of morbidity globally. Among the urological causes of depression is benign prostatic enlargement (BPE). AIM: To determine the prevalence and factors associated with depressive symptoms among BPE patients. SETTING: This study was conducted in the Urology and Family Medicine Clinic at the Aga Khan University Hospital, Nairobi and Urology clinic at the Aga Khan Hospital Mombasa. METHODS: The study was a cross-sectional design recruiting 308 males above the age of 40. Patient Health Questionnaire-9 and International Prostate Symptom Score (IPSS) were used to assess depressive symptoms and lower urinary tract symptoms (LUTS), respectively. Association between depressive symptoms and LUTS was determined. Factors associated with depressive symptoms were analysed by logistic regression. RESULTS: Prevalence of depressive symptoms among patients with symptomatic benign prostatic enlargement (sBPE) was 42.90%. Factors associated with depressive symptoms included comorbid conditions, medication side effects, reduced libido, alcohol use, disturbed sleep at night and anxiety in regard to the prostate condition. CONCLUSION: There is a high prevalence of depressive symptoms among men with BPE. Assessment and early intervention for depressive symptoms among men with BPE should be initiated before clinical depression sets in.Contribution: The study has created a knowledge base on factors associated with depressive symptoms among men with sBPE in the African context.

RESUMEN

BACKGROUND: Holmium laser enucleation of the prostate (HoLEP) is considered a challenging procedure even for surgeons who have completed the learning curve. OBJECTIVES: To assess outcomes and complications following HoLEP performed by a highly experienced surgeon. DESIGN, SETTING, AND PARTICIPANTS: This was a single-institution prospective study (NCT03583034) performed at a tertiary referral centre that included 243 consecutive patients with lower urinary tract symptoms (LUTS) due to benign prostatic enlargement (BPE) treated with HoLEP by a single experienced surgeon (>1600 cases). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Patients were assessed using validated questionnaires and uroflowmetry at baseline and several follow-up dates. Intraoperative and postoperative complications were recorded. Kaplan-Meier analysis was used to estimate recovery rates for urinary continence and erectile function. Logistic regression models were constructed to assess predictors of postoperative complications. RESULTS AND LIMITATIONS: Of the 243 patients, 78 (32.1%) had an indwelling urethral catheter. The median prostate volume (PV) was 87 cm3 (interquartile range 60-115) and 146 patients (59.8%) had PV >80 cm3. At 3-mo follow-up, 219 patients (90.1%) had a peak flow rate >20 ml/s and 182 (74.9%) had no postvoid residual urine. The improvement in subjective symptoms was significant at 1-mo follow-up and was maintained until 12 mo after surgery. Urinary continence recovery was slow, with an estimated rate of 68% (95% confidence interval [CI] 62-74%) at 1 mo and 94% (95% CI 91-97%) at 12 mo after HoLEP. The recovery rate for erectile function was 53% (95% CI 46-61%) at 1 mo and 85% (95% CI 77-90%) at 12 mo. Postoperative complications occurred in 36 patients (14.8%) during their hospital stay, in 34 (14%) within 1 mo following discharge from hospital, and in ten (4.1%) at later follow-up dates. Clinically significant complications (Clavien-Dindo ≥2) were observed in 44 cases (18%) and were more common for patients with an indwelling catheter at baseline (odds ratio 5.05; p = 0.006). CONCLUSIONS: HoLEP is an effective procedure for treating LUTS due to BPE, although it is not devoid of complications and sequelae, even in the hands of a highly experienced surgeon. PATIENT SUMMARY: Holmium laser treatment of the prostate to reduce its size has positive results for urinary function when performed by an experienced surgeon, even in complex cases, although there can be complications.

RESUMEN

Background: To investigate the effect of systemic hypertension on the prostatic artery resistive indices by a comparative ultrasonographic evaluation of the prostate gland in normotensive and hypertensive patients with benign prostatic enlargement (BPE). Materials and methods: The participants had BPE and presented at the outpatient urologic clinic of a tertiary hospital. They were divided into normotensive and hypertensive groups. Each group had fifty patients. Calculation of international prostate symptom score, measurement of blood pressure, and transrectal ultrasonographic evaluation were done. Results: The mean age for the normotensive and hypertensive groups were 66.9 ± 9.8 and 66.0 ± 10.7 years, respectively (P = 0.662). Patients with hypertensive BPE had a significantly higher mean transitional zone volume, transitional zone index, presumed circle area ratio, quality of life score, and prostatic arterial resistive indices than the age-matched normotensive BPE patients. Conclusion: Patients with BPE and with hypertension had significantly higher prostate arteries resistive indices than normotensives with BPE. Even in patients with BPE and controlled hypertension, the prostatic artery resistance indices were still elevated than that of normotensive men with BPE.

RESUMEN

BACKGROUND: To compare the efficacy and safety of bipolar transurethral vaporization of the prostate (B-TUVP) with holmium laser enucleation of the prostate (HoLEP) for moderate [prostate volume (PV) 30-80 ml] and large (≥ 80 ml) benign prostatic enlargement (BPE). MATERIALS AND METHODS: Male patients with lower urinary tract symptom (LUTS) or urinary retention who underwent B-TUVP or HoLEP treatment in two regional centers were respectively enrolled. Patient characteristics and treatment outcomes were retrospectively compared between B-TUVP and HoLEP. RESULTS: In patients with moderate and large prostate volume,B-TUVP showed shorter operative time (P < 0.001) and less hemoglobin decrease (P < 0.001) than in HoLEP. In uncatheterised patients, voiding symptoms and patients' quality of life improved after B-TUVP and HoLEP, but these improvement rates were consistently bigger in HoLEP than in B-TUVP. In catheterised patients, the rate of achieving catheter-free status after surgery was higher in HoLEP than in B-TUVP for patients with PV > 80 ml.(P < 0.001) The incidence of postoperative fever was higher in B-TUVP than in HoLEP for patients with PV 30-80 ml (P < 0.001) but not for those with PV > 80 ml.(P=0.08) The Incidence of postoperative stress incontinence(SUI) was higher in HoLEP than in B-TUVP for patients with moderate and large prostate volume. CONCLUSIONS: There are few studies that investigated the short-term efficacy and safety of second-generation B-TUVP in comparison with HoLEP for moderate and large BPE. Improvement in LUTS and achievement of catheter-free status were predominant in HoLEP, and these outcomes were more prominent in patients with large BPE of PV > 80 ml. However, B-TUVP resulted in less blood loss, shorter operative duration, and less SUI suggesting that B-TUVP is also well-tolerated surgical modality.

RESUMEN

BACKGROUND: It is unclear how cumulative multivariable effects of clinically relevant covariates impact response to pharmacological treatments for lower urinary tract symptoms (LUTS)/benign prostatic enlargement (BPE). OBJECTIVE: To develop models to predict treatment response in terms of International Prostate Symptom Score (IPSS) and the risk of acute urinary retention (AUR) or BPE-related surgery, based on large data sets and using as predictors baseline characteristics that commonly define the risk of disease progression. DESIGN, SETTING, AND PARTICIPANTS: A total of 9167 patients with LUTS/BPE at risk of progression in three placebo-controlled dutasteride trials and one comparing dutasteride, tamsulosin, and dutasteride + tamsulosin combination therapy (CT) were included in the analysis to predict response to placebo up to 24 mo and active treatment up to 48 mo. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Predictors included age, IPSS, total prostate volume (PV), maximum urinary flow rate (Qmax), prostate-specific antigen, postvoid residual urine (PVR), α-blocker usage within 12 mo, and randomised treatment. A generalised least-squares model was developed for longitudinal IPSS and a Cox proportional-hazards model for time to first AUR/surgery. RESULTS AND LIMITATIONS: The vast majority of patients benefit from dutasteride or CT when compared with tamsulosin alone. The predicted IPSS improvement with dutasteride or CT increased with greater PV and severity of symptoms at baseline. The tamsulosin effect was lower with greater baseline PV and tended to decrease over time. Predicted AUR/surgery risk was greater with tamsulosin versus CT or dutasteride; this risk increased with larger PV, higher PVR, and lower Qmax (all at baseline). An educational interactive web-based tool facilitates visualisation of the results (www.bphtool.com). Limitations include: the placebo and active-treatment predictions are from different studies, the lack of similar studies for external validation, and the focus on a population at risk of progression from the 4-yr CombAT study. CONCLUSIONS: Predictive modelling based on large data sets and visualisation of the risk for individual profiles can improve our understanding of how risk factors for disease progression interact and affect response to different treatments, reinforcing the importance of an individualised approach for LUTS/BPE management. PATIENT SUMMARY: We used data from previous studies to develop statistical models for predicting how men with lower urinary tract symptoms or benign prostate enlargement and at risk of disease complications respond to certain treatments according to their individual characteristics.
