RESUMEN

OBJECTIVE: With the development of analytical methods, mathematical models based on humoral biomarkers have become more widely used in the medical field. This study aims to investigate the risk factors associated with the occurrence of bladder spasm after transurethral resection of the prostate (TURP) in patients with prostate enlargement, and then construct a nomogram model. MATERIALS AND METHODS: Two hundred and forty-two patients with prostate enlargement who underwent TURP were included. Patients were divided into Spasm group (n=65) and non-spasm group (n=177) according to whether they had bladder spasm after surgery. Serum prostacyclin (PGI2) and 5-hydroxytryptamine (5-HT) levels were measured by enzyme-linked immunoassay. Univariate and multivariate logistic regression were used to analyze the risk factors. RESULTS: Postoperative serum PGI2 and 5-HT levels were higher in patients in the Spasm group compared with the Non-spasm group (P<0.05). Preoperative anxiety, drainage tube obstruction, and elevated postoperative levels of PGI2 and 5-HT were independent risk factors for bladder spasm after TURP (P<0.05). The C-index of the model was 0.978 (0.959-0.997), with a χ2 = 4.438 (p = 0.816) for Hosmer-Lemeshow goodness-of-fit test. The ROC curve to assess the discrimination of the nomogram model showed an AUC of 0.978 (0.959-0.997). CONCLUSION: Preoperative anxiety, drainage tube obstruction, and elevated postoperative serum PGI2 and 5-HT levels are independent risk factors for bladder spasm after TURP. The nomogram model based on the aforementioned independent risk factors had good discrimination and predictive abilities, which may provide a high guidance value for predicting the occurrence of bladder spasm in clinical practice.

RESUMEN

BACKGROUND: To evaluate the 10-year functional outcomes (primary) and frequency and predictors of BPH surgical retreatment (secondary) after ThuLEP. MATERIALS AND METHODS: A single-center retrospective analysis of consecutive patients undergoing ThuLEP between 2010 and 2013 was performed. Inclusion criteria were: age ≥ 40 years, prostate volume (PV) ≥ 80 mL, International Prostate Symptom Score (IPSS)-Total score ≥ 8 points. IPSS-Total score was the primary outcome, and BPH surgical retreatment rate was the secondary outcome. Paired t-test, McNemar test, and Wilcoxon signed-rank test were used to compare variables. Logistic regression analysis was performed to evaluate predictors of surgical retreatment. RESULTS: A total of 410 patients with a mean ±SD age of 63.9 ± 9.7 years and a PV of 115.6 ± 28.6 mL were included. Mean ±SD follow-up was 108.2 ± 29.6 months. IPSS-Total score was significantly improved at 1 year compared to baseline (23.3 ± 4.7 vs. 10.3 ± 3.8; p<0.001). It was similar after 5 years (10.5 ± 3.6 vs. 10.7 ± 5.0; p=0.161), with a significant worsening at 10 years (10.3 ±4.8 vs. 13.8 ±4.5; p=0.042) but remaining statistically and clinically better than baseline (13.8 ±4.5 vs. 22.1 ±4.3; p<0.001). After 10 years, 21 (5.9%) patients had undergone BPH reoperation. Baseline PV (adjusted OR 1.27, 95% CI 1.09-1.41; p<0.001) and time from BPH surgery (adjusted OR 1.32, 95% CI 1.15-1.43; p<0.001) were predictors of BPH surgical retreatment. CONCLUSIONS: ThuLEP is associated with optimal functional outcomes and a low frequency of BPH surgical retreatment in the long-term. Baseline PV and time from surgery were predictors of BPH reoperation.

RESUMEN

INTRODUCTION: Men with detrusor underactivity (DUA) and concomitant bladder outlet obstruction (BOO) due to benign prostatic enlargement (BPE) may present poorer functional outcomes after surgical desobstruction. This study aimed to evaluate the safety and efficacy of BPE surgery in men with DUA compared with those with normal detrusor contractility (NC). MATERIALS AND METHODS: This review was performed according to the 2020 PRISMA framework. A comprehensive literature search was performed until May 7, 2023, using MEDLINE, EMBASE, and Cochrane Database. No date limits were imposed. Only comparative studies were accepted. The primary endpoint was to assess if there was any difference in short- and long-term functional outcomes after BPE surgery in men with DUA and NC. The secondary endpoint was to evaluate the differences in perioperative outcomes and postoperative complications between the two groups. Meta-analysis was performed using Review Manager (RevMan) software. RESULTS: There were 5 prospective nonrandomized studies and 12 retrospective studies, including 1701 DUA and 1993 NC patients. Regarding surgical procedures, there were eight TURP (transurethral resection of the prostate) studies, four GreenLight PVP (photoselective vaporization of the prostate) studies, two HoLEP (Holmium laser enucleation of the prostate) studies, one GreenLight PVP/HoLEP study, one Holmium laser incision of the prostate study, and one study did not report the type of surgery. We did not find a statistically significant difference between the two groups in terms of perioperative outcomes, including postoperative catheterization time, hospitalization time, urinary retention, need to recatheterization, transfusion rate, or urinary tract infections. Also, we found no significant differences in long-term complications, such as bladder neck stenosis or urethral stenosis. Posttreatment bladder recatheterization and retreatment rate for BPE regrowth could not be evaluated properly, because only one study reported these findings. When we analyzed functional outcomes at 3 months, those with NC had lower International Prostatic Symptom Score (IPSS), lower quality-of-life (QoL) score, better maximum flow rate (Qmax), and lower post-voiding residual (PVR) of urine. These results were maintained at 6 months postoperatively, with exception of PVR that showed no difference. However, at 12 and more than 12 months the functional outcomes became similar regarding IPSS and QoL. There were few data about Qmax and PVR at longer follow-up. CONCLUSION: In this meta-analysis, data suggest that BOO surgical treatment in patients with concomitant BPE and DUA appears to be safe. Despite patients with DUA may present worse functional outcomes in the short postoperative term compared with the NC population, IPSS and QoL scores become comparable again after a longer follow-up period after surgery.

RESUMEN

OBJECTIVES: Lower urinary tract symptoms due to benign prostatic hyperplasia in men increase with aging. Risks related to anesthesia and surgery have led a search for alternative treatments. Bipolar radiofrequency (RF) thermotherapy is one of the methods adopted in patients with high surgical risks. The aim of this study is to compare the effect of bipolar RF thermotherapy and transurethral resection of the prostate (TURP) methods on voiding symptoms and on post-operative complication rates especially in patients carrying high surgical risks. METHODS: Pre-operative, post-operative 1st and 6th month International Prostate Symptom Score (IPSS), Qmax, quality of life, prostate volumes, and postoperative complications of the patients underwent TURP and RF for benign prostatic hyperplasia (BPH) were compared. RESULTS: In the RF group, the pre-operative median IPSS was 30, prostate volume 41.5 cc, post-void residual (PVR) 80 ml, and Qmax is 5.85 ml/s.; In the TURP group, these were 29, 40 cc, 85 ml, and 5.3 ml/sec, respectively. In the Bipolar RF group, post-operative 1st- and 6th-month median values were IPSS 18, 21; prostate volume 40, 40; PVR 40, 35; Qmax 10.9, 9.15 and in the TURP group IPSS 9, 8; prostate volume 20, 20; PVR 30, 10; Qmax 17.25, 19.1, respectively. CONCLUSION: Bipolar RF thermotherapy is an applicable treatment method for BPH patients with high surgical risks.


OBJETIVOS: La termoterapia bipolar por radiofrecuencia es uno de los métodos adoptados en pacientes con alto riesgo quirúrgico. El objetivo de este estudio es comparar el efecto de la termoterapia de radiofrecuencia bipolar y los métodos de RTUP en los síntomas de vaciado y en las tasas de complicaciones posoperatorias, especialmente en pacientes con alto riesgo quirúrgico. MÉTODOS: Se compararon el IPSS, el Qmax, la calidad de vida, los volúmenes de próstata y las complicaciones posoperatorias de los pacientes sometidos a RTUP y RF para la HBP preoperatorios, posoperatorios al primer y sexto mes. RESULTADOS: En el grupo de RF, la mediana preoperatoria del IPSS fue de 30, el volumen prostático de 41.5 cc, el PVR de 80 ml y el Qmax de 5.85 ml/seg.; En el grupo RTUP estos fueron 29, 40 cc, 85 ml y 5.3 ml/seg, respectivamente. En el grupo de RF bipolar, los valores medianos postoperatorios del primer y sexto mes fueron IPSS 18, 21; volumen de próstata 40, 40; PVR 40, 35; Qmax 10.9, 9.15 y en el grupo TURP IPSS 9, 8; volumen de próstata 20, 20; PVR 30, 10; Qmax 17.25, 19.1, respectivamente. CONCLUSIÓN: La termoterapia de RF bipolar es un método de tratamiento aplicable para pacientes con HPB con alto riesgo quirúrgico.

RESUMEN

OBJECTIVE: To determine the factors that may be associated with a 2-month high baseline level of Total Prostatic Specific Antigen (PSA) after endoscopic enucleation of the prostate with Holmium Laser (HoLEP). MATERIALS AND METHODS: Retrospective study of a prospectively collected database of adult males undergoing HoLEP at a single tertiary institution from September 2015 to February 2021. Pre-operative epidemiological, clinical characteristics and post-operative factors were analyzed and a multivariate analysis was performed to determine factors independently related to PSA decline. RESULTS: A total of 175 men aged 49-92 years with a prostate size ranging from 25 to 450 cc underwent HoLEP, and after excluding data from patients due to loss of follow-up or incomplete data, 126 patients were included in the final analysis. The patients were divided into group A (n = 84), which included patients with postoperative PSA nadir lower than 1 ng/ml, and group B(n = 42), with postoperative PSA levels greater than 1 ng/ml. In the univariate analysis there was a correlation between the variation of the PSA value and the percentage of resected tissue (p = 0.028), for each 1 g of resected prostate there was a reduction of 0.104 ng/mL, furthermore there was a difference between the means of age of group A (71.56 years) and group B (68.17 years) (p = 0.042). In the multivariate analysis, the use of statins and lower postoperative PSA levels (p = 0.024; HR = 3.71) were correlated. CONCLUSIONS: Our results indicate that PSA after HoLEP is correlated with patient's age, the presence of incidental prostate cancer, and the use of statins.

RESUMEN

PURPOSE: To evaluate the safety and efficacy of the Optilume BPH Catheter System for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). METHODS: This open-label, single-arm study enrolled eighty subjects with LUTS secondary to BPH who were treated with the Optilume BPH Catheter System. Symptoms were recorded utilizing the International Prostate Symptom Score (IPSS) and Benign Prostatic Hyperplasia Impact Index (BPH-II). Functional improvement was measured utilizing peak urinary flow rate (Qmax) and post-void residual urine volume (PVR). Adverse events were systematically captured and reported at each follow-up visit. RESULTS: Subjects treated with the Optilume BPH Catheter System experienced a significant improvement in LUTS from baseline through 2 years of follow-up, as measured by IPSS (22.3 vs 8.2, p < 0.001) and BPH-II (6.9 vs 2.3, p < 0.001). Functional improvement was also significant, with Qmax improving from an average of 10.9 mL/s at baseline to 17.2 mL/s at the 2-year follow-up and PVR improving from 63.1 to 45.0 mL. Treatment-related adverse events were typically minor, with none occurring between 1- and 2-year post-treatment. CONCLUSIONS: The Optilume BPH Catheter System is a unique minimally invasive surgical therapy that combines mechanical and pharmaceutical aspects for the treatment of BPH. The functional and symptomatic improvements seen after treatment are significant and have been sustained through 2 years in this early feasibility study. REGISTRATION: NCT03423979, registered February 6, 2018.

RESUMEN

PURPOSE: To review and compare the effectivity of novel minimally invasive treatments (MITs) to transurethral resection of the prostate (TURP) for the treatment of lower urinary tract symptoms (LUTS) in men. METHODS: Medline, Embase, and Cochrane databases were searched from January 2010 to December 2022 for randomized controlled trials (RCTs) evaluating MITs, compared to TURP or sham, in men with LUTS. Studies were assessed by risk of bias tool, and evidence by GRADE. Functional outcomes by means of uroflowmetry and IPSS were the primary outcomes, safety and sexual function were secondary outcomes. As part of this review, a network meta-analysis (NMA) was conducted. MITs were ranked based on functional outcome improvement probability. RESULTS: In total, 10 RCTs were included, evaluating aquablation, prostatic urethral lift, prostatic artery embolization (PAE), convective water vapor thermal treatment or temporary implantable nitinol device. All MITs showed a better safety profile compared to TURP. Functional outcome improvement following aquablation were comparable to TURP. In the NMA, aquablation was ranked highest, PAE followed with the second highest probability to improve functional outcomes. Other novel MITs resulted in worse functional outcomes compared to TURP. Level of evidence was low to very low. CONCLUSIONS: Five MITs for treatment of LUTS were identified. Aquablation is likely to result in functional outcomes most comparable to TURP. Second in ranking was PAE, a technique that does not require general or spinal anesthesia. MITs have a better safety profile compared to TURP. However, due to high study heterogeneity, results should be interpreted with caution.

RESUMEN

OBJECTIVE: the aim of this study was to compare the results of open and videolaparoscopic transvesical prostatectomy techniques in the treatment of benign prostatic hyperplasia (BPH) in a tertiary hospital. METHODS: we reviewed medical records of patients who underwent transvesical adenectomy due to BPH between March 2019 and March 2021 at the urology service of Hospital de Clínicas do Paraná (HCPR), 42 patients were included in the open transvesical prostatectomy group and 22 in the videolaparoscopic group. Then, a comparison was made between the techniques in terms of surgical time, bleeding, length of stay, need for intensive care, among others, in addition to postoperative outcome. RESULTS: the mean surgical time was shorter in the open technique compared to the laparoscopic technique (141 min vs 274 min). The videolaparoscopic group had a shorter mean hospital stay (3.5 days vs 6.36 days). There was no statistical significance in the comparison regarding the need for an intensive care unit, as well as in the assessment of postoperative bleeding. CONCLUSION: comparatively, the techniques demonstrated a similar outcome, with a low rate of complications and satisfactory results for the treatment of BPH. The laparoscopic technique is a surgery with a shorter hospital stay, but at the expense of a longer surgical time.

RESUMEN

INTRODUCTION AND OBJECTIVE: Male detrusor underactivity (DUA) definition remains controversial and no effective treatment is consolidated. Transurethral resection of the prostate (TURP) is one of the cornerstones surgical treatments recommended in bladder outlet obstruction (BOO). However, the role of prostatic surgery in male DUA is not clear. The primary endpoint was the clinical and voiding improvement based on IPSS and the maximum flow rate in uroflowmetry (Qmax) within 12 months. MATERIALS AND METHODS: We analyzed an ongoing prospective database that embraces benign prostata hyperplasia (BPH) male patients with lower urinary tract symptoms who have undergone to TURP. All patients were evaluated pre and postoperatively based on IPSS questionnaires, prostate volume measured by ultrasound, postvoid residual urine volume (PVR), Prostate Specific Antigen measurement and urodynamic study (UDS) before the procedure. After surgery, all patients were evaluated at 1-, 3-, 6- and 12-months. Patients were categorized in 3 groups: Group 1-Detrusor Underactive (Bladder Contractility Index (BCI) [BCI] < 100 and BOO index [BOOI] < 40); Group 2-Detrusor Underactive and BOO (BCI < 100 and BOOI ≥ 40); Group 3-BOO (BCI ≥ 100 and BOOI ≥ 0). RESULTS: It was included 158 patients underwent monopolar or bipolar TURP since November 2015 to March 2021. According to UDS, patients were categorized in: group 1 (n = 39 patients); group 2 (n = 41 patients); group 3 (n = 77 patients). Preoperative IPSS was similar between groups (group 1-24.9 ± 6.33; group 2-24.8 ± 7.33; group 3-24.5 ± 6.23). Qmax was statistically lower in the group 2 (group 1-5.43 ± 3.69; group 2-3.91 ± 2.08; group 3-6.3 ± 3.18) as well as greater PVR. The 3 groups presented similar outcomes regard to IPSS score during the follow-up. There was a significant increase in Qmax in the 3 groups. However, group 1 presented the lowest Qmax improvement. CONCLUSION: There were different objective outcomes depending on the degree of DUA at 12 months follow-up. Patients with DUA had similar IPSS improvement. However, DUA patients had worst Qmax improvement than men with normal bladder contraction.

RESUMEN

INTRODUCTION: We assessed the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) in patients with high comorbidity burden. MATERIALS AND METHODS: Data from patients treated with HoLEP at our academic referral center from March 2017 to January 2021 were prospectively collected. Patients were divided according to their CCI (Charlson Comorbidity Index). Perioperative surgical data and 3-month functional outcomes were collected. RESULTS: Out of 305 patients included, 107 (35.1%) and 198 (64.9%) were classified as CCI ≥ 3 and < 3, respectively. The groups were comparable in terms of baseline prostate size, symptoms severity, post-void residue and Qmax. The amount of energy delivered during HoLEP (141.3 vs. 118.0 KJ, p=0.01) and lasing time (38 vs 31 minutes, p=0.01) were significantly higher in patients with CCI ≥ 3. However, median enucleation, morcellation and overall surgical time were comparable between the two groups (all p>0.05). Intraoperative complications rate (9.3% vs. 9.5%, p=0.77), median time to catheter removal and hospital stay were comparable between the two cohorts. Similarly, early (30 days) and delayed (>30 days) surgical complications rates were not significantly different between the two groups. At 3-month follow up, functional outcomes using validated questionnaires did not differ between the two groups (all p>0.05). CONCLUSIONS: HoLEP represents a safe and effective treatment option for BPH also in patients with high comorbidity burden.

RESUMEN

INTRODUCTION: Urolift® is a surgical modality to treat lower urinary tract symptoms (LUTS) in patients with enlarged prostates (1). However, the inflammatory process caused by the device usually displaces the prostate's anatomical landmarks and challenges surgeons performing robotic-assisted radical prostatectomy (RARP). In this video, we will illustrate several technical challenges in patients with Urolift ® who underwent RARP. MATERIAL AND METHODS: We performed a video compilation with several surgical steps illustrating key aspects and critical details of the anterior bladder neck access, lateral bladder dissection from the prostate, and posterior prostate dissection to avoid ureteral and neural bundles injuries. RESULTS: We perform our RARP technique with our standard approach in all patients (2-6). The beginning of the case is performed like every patient with an enlarged prostate. We first identify the anterior bladder neck and then complete its dissection with Maryland and Scissors. However, extra care must be taken in the anterior and posterior bladder neck approach due to the clips found during the dissection. The challenge starts when opening the lateral sides of the bladder until the base of the prostate. It is crucial to perform the bladder neck dissection beginning at the internal plane of the bladder wall. Such dissection is the easiest way to recognize the anatomical landmarks and potential foreign materials, such as clips, placed during previous surgeries. We cautiously work around the clip to avoid using cautery on the top of the metal clips because energy is transmitted from one edge to the other of the Urolift ®. This can be dangerous if the edge of the clip is close to the ureteral orifices. The clips are usually removed to minimize cautery conduction energy. Finally, after isolating and removing the clips, the prostate dissection and subsequent surgical steps are continued with our conventional technique. Before proceeding, we ensure that all clips are removed from the bladder neck to avoid complications during the anastomosis. CONCLUSIONS: Robotic-assisted radical prostatectomy in patients with Urolift ® is challenging due to modified anatomical landmarks and intense inflammatory processes in the posterior bladder neck. When dissecting the clips placed next to the base of the prostate, it is crucial to avoid cautery because energy conduction to the other edge of the Urolift ® can cause thermal damage to the ureters and neural bundles.

RESUMEN

OBJECTIVE: To describe and compare the number of surgeries, mortality rate, length of hospital stay, and costs of transurethral resection of the prostate and open prostatectomy for the treatment of benign prostatic hyperplasia, between 2008 and 2018, in the Public Health System in São Paulo, Brazil. METHODS: Ecological and retrospective study using data from the informatics department of the Brazilian Public Health System database. Procedure codes were "open prostatectomy" and "transurethral resection of the prostate." The outcomes analyzed were compared between transurethral resection of the prostate and open prostatectomy according to the hospital surgical volume and presence or absence of a residency program. RESULTS: A total of 18,874 surgeries were analyzed (77% transurethral resection of the prostate) and overall mortality was not statistically different between procedures. Intermediate and high-volume centers had shorter length of hospital stay than low-volume centers for transurethral resection of the prostate (3.28, 3.02, and 6.58 days, respectively, p=0.01 and p=0.004). Length of hospital stay was also shorter for open prostatectomy in high-volume compared to low-volume centers (4.86 versus 10.76 days, p=0.036). Intrahospital mortality was inversely associated with surgical volume for transurethral resection of the prostate. Centers with residency program had shorter length of hospital stay considering open prostatectomy and less mortality regarding transurethral resection of the prostate. Open prostatectomy was 64% more expensive than transurethral resection of the prostate. CONCLUSION: The findings suggest the importance of investing in specialized centers, which could be potential referral centers for surgical cases.

RESUMEN

Objetivo: Comparar el resultado actual de tres técnicas quirúrgicas en pacientes intervenidos por Hiperplasia Benigna de Próstata (HPB); Enucleación láser de próstata (HoLEP), Resección transuretral (RTU) y Prostatectomía Abierta (PA). Enfermedad que actualmente presenta cambios en su presentación clínica y mayores comorbilidades al momento de la cirugía. Materiales y Método: Análisis retrospectivo de 1. 211 pacientes consecutivos e intervenidos en un mismo centro por HPB entre 2008 y 2017 y con al menos 6 meses de evaluación posoperatoria. Se registró las características periperatorias y comorbilidades, comparando los resultados intra y post operatorios obtenidos según la técnica quirúrgica empleada. Se realizó análisis uni y bivariados en programa SPSS versión 17. Para comparar variables categóricas empleamos test exacto de Fisher y para las variables continuas la prueba de Mann-Whitney. Resultados: Al momento de la cirugía 769 pacientes (63,5%) se encuentran en terapia médica por HPB, 268 (22,1%) presentan retención urinaria y 212 (17,5%) se encuentran en terapia anticoagulante-antiagregante. Se realizó HoLEP en 423 pacientes (36,9%), RTU en 651 (56,9%) y PA en 71 (6,2%). Aquellos intervenidos por HoLEP tienen significativa mayor frecuencia de terapia anticoagulante preoperatoria que RTU (9,2% v/s 4,9 %), manteniendo similar tasa de transfusión en post operatorio (0,5%). La mayor necesidad de transfusión la presentan los intervenidos por PA 5,6%. El tiempo de cateterismo y estadía hospitalaria es significativamente más breve en quienes se someten a HoLEP; 3,7 días v/s 4,4 en RTU y 7,1 en PA. También resultan determinantes del tiempo estadía hospitalaria la edad, presencia de cardiopatía coronaria y falla renal. Al sexto mes de la cirugía los pacientes intervenidos por HoLEP tienen un significativo mejor flujo urinario máximo y menor volumen residual. Conclusiones: En esta serie, los pacientes con HBP al momento de requerir cirugía presentan condiciones que se asocian a mayor tiempo de hospitalización: edad, cardiopatía coronaria y falla renal. Confirmamos que aquellos intervenidos con HoLEP registran una hospitalización significativamente más breve y resultados funcionales similares a RTU y PA.


Aim: To compare the current results of three surgical techniques in patients operated on for Benign Prostate Hyperplasia (BPH); Laser Enucleation of the Prostate (HoLEP), Transurethral Resection (TURP) and Open Prostatectomy (PA). Disease that currently presents changes in its clinical presentation and greater comorbidities at the time of surgery. Materials and Method: Retrospective analysis of 1211 consecutive patients operated on in the same center for BPH between 2008 and 2017 and with at least 6 months of postoperative evaluation. The periperative characteristics and comorbidities were recorded, comparing the intra- and post-operative results obtained according to the surgical technique used. A univariate and bivariate analysis was performed using SPSS version 17. To compare categorical variables, we used Fisher's exact test and the Mann-Whitney test for continuous variables. Results: At the time of surgery 769 patients (63.5%) were on medical therapy for BPH, 268 (22.1%) had urinary retention and 212 (17.5%) were on anticoagulant-antiplatelet therapy. HoLEP was performed in 423 patients (36.9%), TURP in 651 (56.9%) and PA in 71 (6.2%). Those operated on by HoLEP had a significantly higher frequency of preoperative anticoagulant therapy than TURP (9.2% vs. 4.9%), maintaining a similar transfusion rate postoperatively (0.5%). The greatest need for transfusion is presented by those operated on by AP 5.6%. The time of catheterization and hospital stay is significantly shorter in those who undergo HoLEP; 3.7 days v / s 4.4 in TUR and 7.1 in PA. Age, presence of coronary heart disease and kidney failure are also determinants of the length of hospital stay. At the sixth month after surgery, patients operated on by HoLEP had a significantly better peak urinary flow and lower residual volume. Conclusions: In this serie, patients with BPH at the time of requiring surgery, presents conditions that are associated with a longer hospitalization time: age, coronary heart disease and kidney failure. We confirmed that those who underwent HoLEP had a significantly shorter hospitalization and functional results, similar to TURP and AP

RESUMEN

ABSTRACT Objectives: To compare thulium laser enucleation of prostate (ThuLEP) versus laparoscopic trans-vesical simple prostatectomy (LSP) in the treatment of benign prostatic hyperplasia (BPH). Materials and Methods: Data of patients who underwent surgery for "large" BPH (>80mL) at three Institutions were collected and analyzed. Two institutions performed ThuLEP only; the third institution performed LSP only. Preoperative (indwelling catheter status, prostate volume (PVol), hemoglobin (Hb), Qmax, post-voiding residual volume (PVR), IPSS, QoL, IIEF-5) and perioperative data (operative time, enucleated adenoma, catheterization time, length of stay, Hb-drop, complications) were compared. Functional (Qmax, PVR, %ΔQmax) and patient-reported outcomes (IPSS, QoL, IIEF-5, %ΔIPSS, %ΔQoL) were compared at last follow-up. Results: 80 and 115 patients underwent LSP and ThuLEP, respectively. At baseline, median PVol was 130 versus 120mL, p <0.001; Qmax 9.6 vs. 7.1mL/s, p=0.005; IPSS 21 versus 25, p <0.001. Groups were comparable in terms of intraoperative complications (1 during LSP vs. 3 during ThuLEP) and transfusions (1 per group). Differences in terms of operative time (156 vs. 92 minutes, p <0.001), Hb-drop (-2.5 vs. −0.9g/dL, p <0.001), catheterization time (5 vs. 2 days, p <0.001) and postoperative complications (13.8% vs. 0, p <0.001) favored ThuLEP. At median follow-up of 40 months after LSP versus 30 after ThuLEP (p <0.001), Qmax improved by 226% vs. 205% (p=0.5), IPSS decreased by 88% versus 85% (p=0.9), QoL decreased by 80% with IIEF-5 remaining almost unmodified for both the approaches. Conclusions: Our analysis showed that LSP and ThuLEP are comparable in relieving from BPO and improving the patient-reported outcomes. Invasiveness of LSP is more significant.

RESUMEN

OBJECTIVE: We aimed to investigate the rate of urethral stricture development, predictor factors, and the reliability following bipolar transurethral resection of the prostate. METHODS: A total of 124 patients participated in this study. Patient data were retrospectively reviewed. The patients were divided into group 1 (those who developed urethral stricture) and group 2 (those who did not develop urethral stricture). Annual checkups were performed after the postoperative months 1 and 6. The patients were checked by uroflowmetry + post-voiding residue and international index of erectile function. We evaluated the complications that developed during the perioperative period according to the Clavien system. RESULTS: Urethral stricture developed in 10.5% (13/124) of the patients. It was found that patients who underwent transurethral resection of the prostate for the second time (p=0.007), patients with a preoperative catheter or history of catheter insertion (p=0.009), patients with high preoperative median white blood cell (103) counts (p=0.013), and patients with long postoperative catheterization time had a higher rate of urethral stricture after bipolar transurethral resection of the prostate (p=0.046). No grade 4 and grade 5 complications were observed according to the Clavien system in patients. CONCLUSION: Factors such as second transurethral resection of the prostate surgery, history of preoperative catheter insertion, high postoperative white blood cell count, and long postoperative catheterization time increase the risk of urethral stricture after bipolar transurethral resection of the prostate.

RESUMEN

BACKGROUND: This study aimed to explore the prevalence and clinical risk factors in patients diagnosed with incidental prostate cancer (IPC) during certain surgeries (transurethral resection of the prostate [TURP], open prostatectomy [OP], and holmium laser enucleation of the prostate [HoLEP]) after clinically suspected benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Literature search of the MEDILINE, Web of Science, Embase, and Cochrane Library databases was performed to identify eligible studies published before June 2021. Multivariate adjusted odds ratios (ORs) and associated 95% confidence intervals (CIs) of the prevalence and clinical risk factors of IPC were calculated using random or fixed-effect models. RESULTS: Twenty-three studies were included in the meta-analysis. Amongst the 94.783 patients, IPC was detected in 24.715 (26.1%). Results showed that the chance of IPC detection (10%, 95% CI: 0.07-4.00; P<0.001; I2=97%) in patients treated with TURP is similar to that of patients treated with HoLEP (9%, 95% CI: 0.07-0.11; P<0.001; I2=81.4%). However, the pooled prevalence estimate of patients treated with OP was 11% (95% CI: -0.03-0.25; P=0.113; I2=99.1%) with no statistical significance. We observed increased incidence of IPC diagnosis after BPH surgery amongst patients with higher prostate-specific antigen (PSA) level (OR: 1.13, 95% CI: 1.04-1.23; P=0.004; I2=89%), whereas no effect of age (OR: 1.02, 95% CI: 0.97-1.06; P=0.48; I2=78.8%) and prostate volume (OR: 0.99, 95% CI: 0.96-1.03; P=0.686; I2=80.5%) were observed. CONCLUSIONS: The prevalence of IPC was similar amongst patients undergoing TURP, HoLEP, and OP for presumed BPH. Interestingly, increased PSA level was the only independent predictor of increasing risk of IPC after BPH surgery rather than age and prostate volume. Hence, future research should focus on predictors which accurately foretell the progression of prostate cancer to determine the optimal treatment for managing patients with IPC after BPH surgery.
