Pre-prostatectomy membranous urethral length as a predictive factor of post prostatectomy incontinence requiring surgical intervention with an artificial urinary sphincter or a male sling.

AIMS: To ascertain whether the membranous urethral length (MUL) is predictive of postprostatectomy incontinence (PPI) that requires surgery such as artificial urinary sphincter (AUS) or male sling (MS). METHODS: Men who had undergone AUS or MS for PPI were identified from a prospectively maintained database and compared to a control group of men who were continent at 12 months after radical prostatectomy. MUL in sagittal and coronal planes, sphincter height and width were measured on prebiopsy T2-weighted MRI scans. Sphincter volume was estimated as an ellipsoid cylinder. RESULTS: A total of 95 patients (64 AUS and 31 MS) were compared to 60 continent controls. There was no statistical difference in presenting PSA, prostate volume, and T-stage. The mean MUL in sagittal and coronal planes was 11.31 mm (SD: 2.6, range: 6-17 mm) and 11.43 mm (SD: 2.94, range: 5-17 mm) in patients who had AUS and MS, respectively; 15.23 mm (SD: 4.2, range: 8.25-25 mm) and 15.75 mm (SD: 4.1, range: 8-24 mm) in controls (p < 0.01). No men in the PPI surgery group had an MUL >17 mm compared to 35% (20/57 sagittal, 20/58 coronal) of controls. The odds ratio for requiring surgery for PPI was 13.4 for sagittal MUL <9 mm and 3.2 if the MUL <12 mm. CONCLUSIONS: Patients who had surgery for PPI had a significantly shorter MUL and sphincter volume than continent controls. Men with an MUL >17 mm are unlikely to require surgery for PPI whereas an MUL <12 mm significantly increases the risk of requiring surgery for PPI. MUL should be considered when discussing treatment options for prostate cancer.

Safety of "hot" and "cold" site admissions within a high-volume urology department in the United Kingdom at the peak of the COVID-19 pandemic.

OBJECTIVES: To determine the safety of urological admissions and procedures during the height of the COVID-19 pandemic using "hot" and "cold" sites. The secondary objective is to determine risk factors of contracting COVID-19 within our cohort. PATIENTS AND METHODS: A retrospective cohort study of all consecutive patients admitted from March 1 to May 31, 2020 at a high-volume tertiary urology department in London, United Kingdom. Elective surgery was carried out at a "cold" site requiring a negative COVID-19 swab 72-hours prior to admission and patients were required to self-isolate for 14-days preoperatively, while all acute admissions were admitted to the "hot" site.Complications related to COVID-19 were presented as percentages. Risk factors for developing COVID-19 infection were determined using multivariate logistic regression analysis. RESULTS: A total of 611 patients, 451 (73.8%) male and 160 (26.2%) female, with a median age of 57 (interquartile range 44-70) were admitted under the urology team; 101 (16.5%) on the "cold" site and 510 (83.5%) on the "hot" site. Procedures were performed in 495 patients of which eight (1.6%) contracted COVID-19 postoperatively with one (0.2%) postoperative mortality due to COVID-19. Overall, COVID-19 was detected in 20 (3.3%) patients with two (0.3%) deaths. Length of stay was associated with contracting COVID-19 in our cohort (OR 1.25, 95% CI 1.13-1.39). CONCLUSIONS: Continuation of urological procedures using "hot" and "cold" sites throughout the COVID-19 pandemic was safe practice, although the risk of COVID-19 remained and is underlined by a postoperative mortality.

Prevalence of chronic pain following suburethral mesh sling implantation for post-prostatectomy incontinence.

PURPOSE: To evaluate postoperative pain and complications following AdVance™/AdVance™ XP male sling implantation. MATERIALS AND METHODS: A multi-center retrospective medical notes review of patients implanted for bothersome post-prostatectomy incontinence was conducted. All patients were telephoned to provide further information on pain or further complications related to their surgery. Statistical evaluation utilized logistical regression analysis. Additionally, a literature review was conducted reviewing pain outcomes following AdVance™/AdVance™ XP implantation. RESULTS: One-hundred and twenty-seven men were reviewed over an 8-year period. The mean age was 70 years, with mean follow up 52 months. Of those with mild stress urinary incontinence, 45 (79%) had a successful outcome compared to 42 (72%) in the moderate group. Twenty-nine (23%) men reported postoperative pain, with a mean maximal pain score of 6 (range: 0-10). The majority of pain resolved within 4 weeks (19/29 men). A further seven patients resolved by 3 months. Only three men (2.3%) had chronic pain greater than 3 months, which all resolved by 1 year. Men less than 65 years were more likely to suffer pain (p = 0.009). Acute urinary retention occurred in 23 (18%) men and correlated significantly with postoperative pain (p = 0.04). Overactive bladder symptoms, severity of incontinence or radiotherapy were not correlated with postoperative pain. In our cohort, there were no extrusions, divisions, or explantations. CONCLUSION: Approximately a quarter of men experience pain in the early postoperative period. However, the severity and rates of chronic pain (>3 months) are low (2.3%) but all settle within a year.

Long-term outcomes for penile cancer patients presenting with advanced N3 disease requiring a myocutaneous flap reconstruction or primary closure-a retrospective single centre study.

BACKGROUND: Penile cancer patients with advanced metastatic disease in the inguinal region present a therapeutic challenge. We compared the outcomes for patients with advanced inguinal node disease requiring myocutaneous flap reconstruction (MFR) against primary closure for N3 disease. METHODS: A retrospective comparative study of a consecutive cohort of advanced penile cancer patients with N3 disease was performed. Patient demographics, presenting symptoms, primary tumour site, stage and grade were recorded. The type of MFR used, patient outcomes and post-operative complications were recorded from an institutional database. Kaplan-Meier (KM) curves were calculated to analyse the cancer-specific survival (CSS) rates for the MFR group and compared with the no-MFR group. P values were calculated by log-rank and Chi square tests for CSS rates and complications respectively. RESULTS: Eighteen patients requiring MFR were identified; mean age 62 years. Ten (55.6%) patients had a first presentation with penile cancer and advanced nodal disease with the remaining 8 (44.4%) presenting with an inguinal recurrence having already undergone surgery. The majority (n=15) underwent a vertical rectus abdominis myocutaneous (VRAM) flap. The average length of stay was 23 days for the MFR group versus 8.5 days for the no-MFR group. The 5-year CSS was 20.9% for the MFR group and 39.8% for the no-MFR group (P<0.01). CONCLUSIONS: Aggressive surgical management for patients with extensive nodal disease and flap reconstruction is feasible and aids wound management although the long-term prognosis is still poor.

Diagnostic value of MRI-based PSA density in predicting transperineal sector-guided prostate biopsy outcomes.

PURPOSE: Prostate-specific antigen (PSA) density (PSAD) has potential to increase the diagnostic utility of PSA, yet has had poor uptake in clinical practice. We aimed to determine the diagnostic value of magnetic resonance imaging-derived PSAD (MR-PSAD) in predicting transperineal sector-guided prostate biopsy (TPSB) outcomes. MATERIALS AND METHODS: Men presenting for primary TPSB from 2007 to 2014 were considered. Histological outcomes were assessed and defined as: presence of any cancer or significant cancer defined as presence of Gleason 4 and/or maximum tumour core length (MCCL) ≥ 4 mm (G4); or Gleason 4 and/or MCCL ≥ 6 mm (G6). Sensitivity, specificity and positive and negative predictive values were calculated, and receiver operating characteristics (ROC) curves were generated to compare MR-PSAD and PSA. RESULTS: Six hundred fifty-nine men were evaluated with mean age 62.5 ± 9 years, median PSA 6.7 ng/ml (range 0.5-40.0), prostate volume 40 cc (range 7-187) and MR-PSAD 0.15 ng/ml/cc (range 0.019-1.3). ROC area under the curve (95% CI) was significantly better for MR-PSAD than PSA for all cancer definitions (p < 0.001): 0.73 (0.70-0.76) versus 0.61 (0.57-0.64) for any cancer; 0.75 (0.71-0.78) versus 0.66 (0.62-0.69) for G4; and 0.77 (0.74-0.80) versus 0.68 (0.64-0.71) for G6. Sensitivities for MR-PSAD < 0.1 ng/ml/cc were 85.0, 89.9 and 91.9% for any, G4 and G6 cancer, respectively. CONCLUSION: MR-PSAD may be better than total PSA in determining risk of positive biopsy outcome. Its use may improve risk stratification and reduce unnecessary biopsies.
