RESUMO

OBJECTIVE: To analyze the characteristics of public health services related to radical prostatectomy, according to hospital volume of surgeries and stratified as academic and non-academic centers. METHODS: An ecological study was conducted using a database available in TabNet platform of the Unified Health System Department of Informatics. Number of surgeries, length of hospital stay, length of stay in intensive care unit, in-hospital mortality rate, and cost of hospitalization were evaluated. The hospitals were divided into three subgroups according to surgery volume (tercile), and results were compared. The same comparisons were made among academic and non-academic centers. We considered academic centers those providing Urology residency program. RESULTS: A total of 11,259 radical prostatectomies were performed in the city of São Paulo between 2008 and 2018. We observed a significant trend of increase in radical prostatectomies for treating prostate cancer over the years (p=0.007). The length of stay in intensive care unit, and number of deaths were not statistically different among centers with diverse surgery volume, nor between academic and non-academic centers. However, length of hospital stay was significantly shorter in academic centers (p=0.043), while cost of hospitalization was significantly higher in high-volume center compared to low- (p<0.001) and intermediate-volume centers (p<0.001). CONCLUSION: Length of hospital stay for radical prostatectomies performed in public services in the city of São Paulo was shorter in academic centers, whereas hospitals with a high volume of surgeries showed greater cost of hospitalization.

RESUMO

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.

RESUMO

INTRODUCTION: The pandemic caused by the COVID-19 resulted in worldwide social isolation and leading to significant personal distress, particularly among health professionals on the front lines. Those factors' relevance and their impact on sexual function in this population have not yet been established. AIM: To evaluate the impact of the pandemic on sexual function in healthcare professionals and medical students at a reference center in the treatment of COVID-19 in Brazil. METHODS: A cross-sectional analysis with online questionnaires about sexual function was sent to health professionals and medical students from the HC-FMUSP medical complex. The questionnaire evaluated Total Sexual and Masturbatory Frequency prior and during the pandemic, libido and sexual satisfaction changes with a detailed inquire about demographics and personal factors. An objective assessment of sexual function was also made using the validated sexual quotient questionnaires. MAIN OUTCOME MEASURES: Differences in intercourse frequency, libido, and overall sexual satisfaction, in a sample of healthcare professionals particularly vulnerable to the pandemic effects. RESULTS: A total of 1,314 responses were available with a mean age of 37 years. Worsening of sexual satisfaction was reported by 44.5% of the participants, with the following associated factors: Lower libido, missing Nightlife, Higher Masturbatory Frequency, and isolation from the partner. Remaning sexualy actively and having higher sexual frequency appear to decrease the chance of worsening sexual function. Worsening of Libido was reported by 37% and had several associated factors, including missing of Nightlife, older age, isolation from the partner among others. Being male and sexually active was associated with a smaller chance of reporting lower libido. CONCLUSION: We were able to observe a sharp drop in Libido and General Sexual Satisfaction. Although an increase in pornography consumption and masturbatory frequency did occur, these factors were not associated with greater sexual satisfaction. The impact of COVID-19 on this population's sexual health is not to be underestimated and should be further studied in the follow-up of the pandemic.

RESUMO

PURPOSE: The TWIST (Testicular Work-up for Ischemia and Suspected Torsion) score was developed to allow for expedited diagnosis of testicular torsion (TT) in children based on clinical variables: edema (2 points), hard mass (2), absent cremasteric reflex (1), high-riding testis (1) and nausea/vomiting (1). We sought to validate the TWIST Score applied by non-expert physicians for the diagnosis of testicular torsion in an adult population. METHODS: We prospectively analyzed all consecutive males presenting to a tertiary hospital with acute scrotum. Patients with previous scrotal pathology or trauma were excluded. Physical examination was performed by a general surgeon and variables of TWIST were recorded. All patients underwent Scrotal Doppler Ultrasound. Measures of accuracy of the TWIST score and ROC curves were generated to evaluate its performance in diagnosing TT in adults. RESULTS: Of 68 patients, 34 had TT (50%). Median age was 24.9 years. According to the original cutoffs of TWIST, 23 patients had a score ≤ 2 among which none had TT. Fifteen patients had a score of 3-4, among which seven had TT. Thirty patients had a score ≥ 5, among which 27 had TT. All 18 patients with a score of 6 or greater had TT (100% PPV). ROC curve revealed an AUC of 0.95. CONCLUSION: The TWIST Score is valid for the diagnosis of Testicular Torsion in adults, presenting a PPV of 90% for a cutoff of 5 points and 100% for six points. In all patients with a score of 2 or less, the disease could be safely excluded (100% NPV).

RESUMO

OBJECTIVES: To evaluate outcomes of laparoscopic pyeloplasty (LP) in adults with poorly functioning kidney due to ureteropelvic junction obstruction (UPJO). METHODS: A retrospective comparative analysis was performed between adult patients who underwent LP due to UPJO with differential renal function (DRF) ≤ 15% and DRF > 15%. LP success rate and complications were assessed. LP success was defined as symptoms improvement and DRF improvement or stabilization. DRF and estimated glomerular filtration rate (eGFR) were analyzed before and 12 months after surgery to evaluate renal function recovery. DRF was estimated using Tc-99 m DMSA renal scintigraphy. RESULTS: Among 121 LP performed in the study period at our institution, 15 and 42 were included in the DRF ≤ 15% and DRF > 15% groups, respectively. At a median follow-up of 17.8 months, all patients with DRF ≤ 15% reported symptoms improvement. LP success rate was 86.7% and 90.5% (p = 0.65) for patients with DRF ≤ 15% and DRF > 15%, respectively. There were no complications in the DRF ≤ 15% group, while there were three complications recorded in the DRF > 15% group (Clavien 2 and 3b). In the DRF ≤ 15% group, mean pre-operative and post-operative DRF was 9.5% ± 3.6 and 10.5% ± 7.8 (p = 0.49), respectively. Median pre-operative and post-operative eGFR was 68.5 ml/min and 79.8 ml/min (p = 0.93), respectively. Two patients had DRF improvement after LP. CONCLUSIONS: LP in adult patients with UPJO and poor function kidneys is an effective and safe procedure. DRF recovery is seen in a minority of the patients; however, LP is an alternative to nephrectomy.

RESUMO

Calcifying fibrous tumor of the tunica vaginalis is a rare fibrous proliferation, which can sometimes mimic a scrotal malignancy prompting surgical intervention. It has been recognized as a benign lesion, and no recurrence has been described after its resection. Its identification is essential to avoid overtreatment and unnecessary orchiectomy. We herein describe a rare case of calcifying fibrous tumor of the tunica vaginalis in a young patient and review the clinical features of inguinal and scrotal calcifying fibrous tumors to help clinical decisions and encourage a testis sparing surgery.

RESUMO

PURPOSE: To evaluate the expression of urinary biomarkers of inflammation and tissue remodeling in patients with BPH undergoing surgery and evaluate the association of biomarkers with postoperative urodynamic outcomes MATERIALS AND METHODS: We analyzed urine samples from 71 patients treated with TURP from 2011 to 2017. Urinary levels of epidermal growth factor (EGF), matrix-metalloproteinase-1 (MMP-1), interleukin-6 (IL-6), nerve growth factor (NGF) and monocyte-chemoattractant protein-1 (MCP-1) (by commercial ELISA kit) were measured, adjusted by urinary creatinine (Cr) and analyzed according to patients clinical and urodynamic characteristics (baseline and 12-month postoperative urodynamic) RESULTS: MMP-1/Cr levels were significantly higher among subjects with higher detrusor pressure on preoprative urodynamic. MCP-1/Cr levels were significantly higher amongs subjects with preoperative DO. Preoperative levels of NGF/Cr (0.13 vs 0.08, p = 0.005) and MMP-1/Cr (0.11 vs 0.04, p = 0.021) were predictors of persistent DO 12 months after surgery. The following factors were shown to be useful for predicting the persistence of DO in the postoperative period: NGF/Cr, with an AUC of 0.77 (95% CI 0.62-0.92) (p = 0.006), and MMP-1/Cr, with an AUC of 0.72 (95% CI 0.56-0.88) (p = 0.022). CONCLUSIONS: MMP-1/Cr was associated with higher detrusor pressure and MCP-1/CR with DO. NGF/Cr and MMP-1/Cr were shown to be predictors of persistent postoperative DO.

RESUMO

PURPOSE: Failure after pyeloplasty for ureteropelvic junction obstruction in children may occur in up to 10% of cases. Therapeutic options include Double-J® stent placement, endoscopic treatment and reoperation. Laparoscopic and robotic reoperative modalities seem safe and efficacious, although pediatric series are limited in the literature. We report the largest known series of reoperative laparoscopic ureteropelvic junction obstruction repair in children and compare this approach to primary laparoscopic pyeloplasty. MATERIALS AND METHODS: We reviewed all children undergoing laparoscopic pyeloplasty at a single institution from 2004 to 2015. Reoperative laparoscopic ureteropelvic junction obstruction repair was compared to primary pyeloplasty. Groups were analyzed regarding demographics, operative time, complications, length of hospital stay and success, defined by improvement of symptoms, ultrasound and renogram. RESULTS: We identified 11 cases of reoperation (8 redo pyeloplasties and 3 ureterocalycostomies) and 71 primary pyeloplasties. Groups were not different in age, gender or weight. Median followup was 37 months. Median time between primary pyeloplasty and reoperation was 34 months. Median operative time was 205 minutes for the reoperative group and 200 for primary pyeloplasty (p = 0.98). Length of stay was longer in the reoperative group (p = 0.049), although no major complications were recorded in this group. All reoperative cases and 96% of primary pyeloplasty cases remained asymptomatic following surgery (p = 0.99). Postoperative improvement was similar for both groups on ultrasound (90% for reoperation vs 92% for primary pyeloplasty, p = 0.99) and renogram (80% vs 88%, p = 0.6). CONCLUSIONS: Laparoscopy seems to be safe and effective for management of failed pyeloplasty in children. Based on our data, reoperation is as safe and effective as primary pyeloplasty.
