Purpose:To identify incidence and predictors of stress urinary incontinence (SUI) following Holmium laser enucleation of the prostate (HoLEP).Materials and methods:We performed a retrospective review of 589 HoLEP patients from 2012-2018. Patients were assessed at pre-operative and post-operative visits. Univariate and multivariate regression analyses were performed to identify predictors of SUI.Results:52/589 patients (8.8%) developed transient SUI, while 9/589 (1.5%) developed long-term SUI. tSUI resolved for 46 patients (88.5%) within the first six weeks and in 6 patients (11.5%) between 6 weeks to 3 months. Long-term SUI patients required intervention, achieving continence at 16.4 months on average, 44 men (70.9%) with incontinence were catheter dependent preoperatively. Mean prostatic volume was 148.7mL in tSUI patients, 111.6mL in long-term SUI, and 87.9mL in others (p < 0.0001). On univariate analysis, laser energy used (p < 0.0001), laser "on" time (p=0.0204), resected prostate weight (p < 0.0001), overall International Prostate Symptom Score (IPSS) (p=0.0005), and IPSS QOL (p=0.02) were associated with SUI. On multivariate analysis, resected prostate weight was predictive of any SUI and tSUI, with no risk factors identified for long-term SUI.Conclusion:Post-HoLEP SUI occurs in ~10% of patients, with 1.5% continuing beyond six months. Most patients with tSUI recover within the first six weeks. Prostate size >100g and catheter dependency are associated with increased risk tSUI. Larger prostate volume is an independent predictor of any SUI, and tSUI.

BackgroundWe examine the practical application of multiparametric MRI (mpMRI) prostate biopsy data using established pre-RP nomograms and its potential implications on RP intraoperative decision-making. We hypothesize that current nomograms are suboptimal in predicting outcomes with mpMRI targeted biopsy (TBx) data.Materials and methodsPatients who underwent mpMRI-based TBx prior to RP were assessed using the MSKCC and Briganti nomograms with the following iterations: (1) Targeted (T) (targeted only), (2) Targeted and Systematic (TS) and (3) Targeted Augmented (TA) (targeted core data; assumed negative systematic cores for 12 total cores). Nomogram outcomes, lymph node involvement (LNI), extracapsular extension (ECE), organ-confined disease (OCD), seminal vesicle invasion (SVI), were compared across iterations. Clinically significant impact on management was defined as a change in LNI risk above or below 2% (Δ2) or 5% (Δ5).ResultsA total of 217 men met inclusion criteria. Overall, the TA iteration had more conservative nomogram outcomes than the T. Moreover, TA better predicted RP pathology for all four outcomes when compared with the T. In the entire cohort, Δ2 and Δ5 were 16.6-25.8% and 20.3-39.2%, respectively. In the subset of 190 patients with targeted and systematic cores, TA was a better approximation of TS outcomes than T in 71% (MSKCC) and 82% (Briganti) of patients.ConclusionIn established pre-RP nomograms, mpMRI-based TBx often yield variable and discordant results when compared with systematic biopsies. Future nomograms must better incorporate mpMRI TBx core data. In the interim, augmenting TBx data may serve to bridge the gap.

A significant workforce shortage of urologists available to serve the US population has been projected to occur over the next decade. Accordingly, much of the management of urologic patients will need to be assumed by other specialties and practitioners. Since primary care physicians are often first evaluate common urologic complaints, it makes sense that these physicians are in an excellent position to intervene in the management of these patients when appropriate. One of the most common complaints in urology is voiding dysfunction. The incidence of voiding dysfunction increases with age, with conservative estimates showing that over 50% of elderly patients suffer. Despite this high prevalence and its negative impact on quality of life, however, few seek or receive treatment, as many do not readily disclose these impactful yet personal symptoms. We sought to summarize the typical presentation, evaluation, assessment and therapeutic options for both male and female patients presenting with voiding dysfunction.

Objective: To provide the first comprehensive analysis of the Twitterverse amongst academic urologists and programmes in North America. Methods: Using national accreditation and individual programme websites, all active urology residency programmes (USA and Canada) and academic Urology faculty at these programmes were identified. Demographic data for each programme American Urological Association [AUA] section, resident class size) and physician (title, fellowship training, Scopus Hirsch index [H‐index] and citations) were documented. Twitter metrics (Twitter handle, date joined, # tweets, # followers, # following, likes) for programmes and physicians were catalogued (data capture: March–April 2019). Descriptive analyses and temporal trends in Twitter utilisation amongst programmes and physicians were assessed. Multivariable logistic regression was used to identify predictors of Twitter use. Results: In all, 156 academic programmes (143 USA, 13 Canada) and 2214 academic faculty (2015 USA, 199 Canada) were identified. Twitter utilisation is currently 49.3% and 34.1% amongst programmes and physicians, respectively, and continues to increase. On multivariable analysis, programmes with 3–5 residents/year and programmes with a higher percentage of faculty Twitter engagement were more likely to have Twitter accounts. From a physician perspective, those with fellowship training, lower academic rank (Clinical Instructor, Assistant Professor, Associate Professor vs Professor) and higher H‐indices were more likely to have individual Twitter accounts. Conclusion: There is a steady increase in Twitter engagement amongst Urology programmes and academic physicians. Faculty Twitter utilisation is an important driver of programme Twitter engagement. Twitter social media activity is strongly associated with academic productivity, and may in fact drive academic metrics. Within Urology, social media presence appears to be proportional to academic activity. [ABSTRACT FROM AUTHOR]
