Online Collaborative Learning in Urology.

REASON FOR REVIEW: A recent shift towards use of telehealth and remote learning has significant implications on resident and fellow education in urology. Implementation of multi-institutional online didactic programs, spurred on by the COVID epidemic, has changed the traditional resident teaching paradigm from individual institutional silos of knowledge and expertise to a shared nationwide database of learning.  RECENT FINDINGS: In this article, we explore the current trend towards virtual education and its progress to date, lessons learned on the optimization of this teaching modality, and future direction and sustainability of collaborated, standardized and accessible didactic education in urology. Multi-institutional collaborative remote video didactics has emerged as a critical part of resident education. These lectures have been overwhelmingly successful and have persisted beyond the pandemic to become a part of the urologic training curricula. This collaborative and standardized approach to resident education provides access to national and international experts, encourages cross-institutional collaboration and discussion, and builds a repository of lectures with easy access for learners. Utilization of this teaching modality will continue to be impactful in urologic training and will require ongoing efforts and input from both collaborating intuitions and professional societies to continue to improve on and engage in this important learning tool.

Urinary Stone Disease in Pregnancy: A Claims Based Analysis of 1.4 Million Patients.

PURPOSE: Urinary stone disease during pregnancy is poorly understood but is thought to be associated with increased maternal and fetal morbidity. We determined the prevalence of urinary stone disease in pregnancy and whether it is associated with adverse pregnancy outcomes. MATERIALS AND METHODS: We identified all pregnant women from 2003 through 2017 in the Optum® national insurance claims database. We used diagnosis claims to identify urinary stone disease and assess medical comorbidity. We established the prevalence of urinary stone disease during pregnancy stratified by week of pregnancy. We further evaluated associations among urinary stone disease, maternal complications and pregnancy outcomes in univariable and multivariable analyses. RESULTS: Urinary stone disease affects 8 per 1,000 pregnancies and is more common in white women and women with more comorbid conditions. In fully adjusted models pregnancies complicated by urinary stone disease had higher rates of adverse fetal outcomes including prematurity and spontaneous abortions. This analysis is limited by its retrospective, administrative claims design. CONCLUSIONS: The rate of urinary stone disease during pregnancy is higher than previously reported. Urinary stone disease is associated with adverse pregnancy outcomes.

Inflatable Penile Prosthesis Placement, Scratch Technique and Postoperative Vacuum Therapy as a Combined Approach to Definitive Treatment of Peyronie's Disease.

PURPOSE: Peyronie's disease is a devastating condition resulting in penile malformation, erectile dysfunction, pain and emotional distress. In this prospective, 2 institution study we evaluated a multimodal surgical and mechanical combined approach to the definitive treatment of Peyronie's disease and concomitant erectile dysfunction. MATERIALS AND METHODS: A total of 145 select patients underwent endocavernous disruption of Peyronie's disease plaques via the scratch technique, followed by inflatable penile prosthesis insertion. Postoperatively patients were assigned to vacuum device therapy for 3 minutes twice daily to continue penile curvature correction. Followup continued for 1 year after surgery. Anatomical and functional results were assessed. RESULTS: Patients with plaques in the proximal third, middle third and subcoronal areas of the penis had a mean ± SD postoperative residual curvature of 21.5 ± 4.5, 17.3 ± 4.8 and 14.1 ± 3.1 degrees, respectively. After 24 weeks of vacuum therapy the mean penile curvature deviation decreased to 8.7 ± 2.5, 9.1 ± 2.9 and 7.7 ± 0.9 degrees, respectively. The mean IIEF-5 (International Index of Erectile Function) score was 9.8 ± 2.3 preoperatively, 18.9 ± 3.1 at 6 months (p <0.001) and 24.1 ± 3.6 at 1 year (p <0.001). The mean EDITS (Erectile Dysfunction Inventory of Treatment Satisfaction) score at the end of followup was 64.6 ± 11.8. Operative and postoperative complications were minimal. CONCLUSIONS: Our novel combination of intraoperative and postoperative therapies in the treatment of patients with Peyronie's disease and an inflatable penile prosthesis was safe and efficacious with excellent functional outcomes. Penile curvature corrections were statistically significant and complications were negligible.

Distal Corporal Anchoring Stitch: A Technique to Address Distal Corporal Crossovers and Impending Lateral Extrusions of a Penile Prosthesis.

BACKGROUND: Unidentified distal crossovers, delayed distal crossovers, and impending lateral extrusion are complications of penile prosthesis implant insertion but are not as common as prosthesis infection or mechanical failure. AIM: To evaluate results of a surgical technique, the distal corporal anchoring stitch, that addresses fixation of the penile prosthesis in patients with these complications. METHODS: A lateral sub-coronal incision is used on the side where the crossover or laterally extruding cylinder should be positioned. Dissection is carried through the Buck fascia, followed by a transverse incision of the tunica albuginea, where the distal aspect of the affected cylinder is delivered. A 4-0 PDS suture is threaded through the distal cylinder ring of the implant. A new, properly positioned intracorporal channel is created and the suture is passed through the distal end of the channel. Once the suture is through the glans and the cylinder is in the correct position, a small cruciate incision is made on the glans at the location of the anchor stitch. The suture is tied with the knot buried in the glans tissue. OUTCOMES: Fifty-three patients underwent treatment of their distal penile implant crossover with a distal corporoplasty using this method and their anatomic and functional outcomes and overall satisfaction were evaluated. RESULTS: This technique ensured that the cylinder remained in the newly created, appropriately positioned channel. No patients developed infections, wound-healing defect, glandular hypoesthesia, anesthesia, or altered sensation or pain in the glans related to the suture and only two reported recurrence of a lateral herniation that did not require further treatment. CLINICAL IMPLICATIONS: Distal fixation of the penile prosthesis is a useful surgical adjunct to treating patients with prosthetic lateral extrusions or crossovers that can be applied in almost all cases. STRENGTHS AND LIMITATIONS: Considering these rare complications, our experience is based on a relatively large number of patients and showed a low incidence of complications and a high satisfaction rate. The main limitation of this study is the retrospective nature of the data and the series included patients from two high-volume surgeons that might not be generalizable to all practices. CONCLUSION: The distal corporal anchoring stitch is safe and effective in securing distal fixation of the extruding inflatable penile prosthesis. Antonini G, Busetto GM, Del Giudice F, et al.

Utilization of cytoreductive nephrectomy and patient survival in the targeted therapy era.

We sought to analyze utilization and survival outcomes of cytoreductive nephrectomy (CN) in patients with metastatic renal cell carcinoma (RCC) before and after introduction of targeted therapy. We identified patients with metastatic RCC between 1993 and 2010 in the SEER registry and examined temporal trends in utilization. We performed a joinpoint regression to determine when changes in utilization of CN occurred. We fitted multivariable proportional hazard models in full and propensity score-matched cohorts. We performed a difference-in-difference analysis to compare survival outcomes before and after introduction of targeted therapy. The proportion of patients undergoing CN increased from 1993 to 2004, from 29% to 39%. We identified a primary joinpoint of 2004, just prior to the introduction of targeted therapy. Beginning in 2005, there was a modest decrease in utilization of CN. CN was associated with a lower adjusted relative hazard (0.41, 95% confidence interval 0.34­0.43). Median survival among patients receiving CN increased in the targeted therapy era (19 vs. 13 months), while median survival among patients not receiving CN increased only slightly (4 vs. 3 months). Difference-in-difference analysis showed a significant decrease in hazard of death among patients who received CN in the targeted therapy era. Despite decreased utilization in the targeted therapy era, CN remains associated with improved survival. Prospective randomized trials are needed to confirm the benefit of CN among patients with metastatic RCC treated with novel targeted therapies.

Procedures needed to maintain functionality of adult continent catheterizable channels: a comparison of continent cutaneous ileal cecocystoplasty with tunneled catheterizable channels.

PURPOSE: We compared the outcomes of various adult continent catheterizable channels in a multi-institutional setting. MATERIALS AND METHODS: We retrospectively reviewed the records of all adults who underwent construction of a continent catheterizable channel at our 4 institutions from 2004 to 2013 and who had at least 6 months of followup. Patients were stratified by channel type, including continent cutaneous ileal cecocystoplasty or tunneled cutaneous channel, eg appendicovesicostomy, Monti channel, etc. The primary study outcome was the need for a secondary procedure to correct stomal leakage, catheterizable channel obstruction or stomal stenosis. Secondary outcomes were patient reported leakage and 30-day postoperative complications. We used Firth logistic regression to control for the heterogeneity induced by multiple institutions. RESULTS: A total of 61 patients were included in study, of whom 31 underwent continent cutaneous ileal cecocystoplasty. Mean age was 41.4 years (range 22 to 76). Median followup was 16 months. More patients with a tunneled channel required a secondary procedure than those with cecocystoplasty (15 of 30 or 50% vs 4 of 31 or 13%, OR 6.4, 95% CI 1.8-28). The total number of required secondary procedures was also greater for tunneled channels than for cecocystoplasty (27 vs 4). Of patients with cecocystoplasty 29% reported stomal leakage compared with 43% of those with a tunneled channel (p = 0.12). A high rate of postoperative complications was observed regardless of technique, including 40% for channels and 51.7% for cecocystoplasty. CONCLUSIONS: Patients with continent cutaneous ileal cecocystoplasty undergo fewer interventions to maintain the catheterizable channel than patients with a tunneled continent catheterizable channel.

Prostate size does not predict high grade cancer.

PURPOSE: Several radical prostatectomy series have linked small prostates with high grade cancer based on the hypothesis that a small prostate results from a low androgen milieu that selects for less hormone dependent, more aggressive tumors. We previously reported that this association resulted from ascertainment bias from the performance characteristics of prostate specific antigen rather than from tumor biology in our radical prostatectomy cohort. In this study we analyzed this association in a more generalized population of men who underwent prostate needle biopsy. MATERIALS AND METHODS: The prostate needle biopsy database at our institution was queried for all initial biopsies. Included patient characteristics were age, race, family history of prostate cancer, prostate specific antigen, abnormal digital rectal examination and prostate volume in ml on transrectal ultrasound. Multivariate logistic regression was used to determine the influence of prostate volume on the odds of high grade cancer. RESULTS: The study population included 1,295 patients during 2000 to 2010, of whom 582 (44.9%) had prostate cancer and 398 (30.7%) had high grade cancer. When all patients were pooled, the OR for high grade cancer was 0.85 (95% CI 0.78-0.92) for each 10 ml increase in prostate volume. When patients were divided by clinical T stage, the corresponding ORs for those with T1c disease was 0.83 (95% CI 0.74-0.93) and for those with T2 or greater disease it was 0.99 (0.98-1.00). CONCLUSIONS: The association between small prostates and high grade cancer exists only in men with clinical T1c (normal digital rectal examination) prostate cancer. It likely resulted from ascertainment bias due to the performance characteristics of prostate specific antigen rather than tumor biology.

Risk of Postpartum Urinary Stone Disease in Women with History of Urinary Stone Disease During Pregnancy.

Objective: To determine the risk of postpartum urinary stone disease in women with a history of stone disease during pregnancy. Methods: Using the Optum® de-identified Clinformatics® Datamart we identified pregnant women with urinary stone disease in the United States between January 2003 to December 2017 by standardized International Classification of Diseases Ninth and Tenth Editions (ICD-9 and ICD-10), and Current Procedural Terminology code criteria. We limited the cohort to include women without evidence of urinary stone disease before pregnancy. We abstracted patient demographic characteristics, clinical risk factors for stone disease, and data for urinary stone disease encounters and related procedures after pregnancy. Encounters occurring within 1 year of pregnancy were excluded. Cox proportional hazard models were used to analyze for significance. Results: We identified a total of 1,395,783 pregnant women with a median postpartum follow-up of 4.0 years, including 5971 (0.4%) women with a urinary stone during pregnancy. Of these, 736 (12.3%) had an additional urinary stone diagnosis claim after pregnancy, compared with 13,275 (0.95%) women without a history of stone disease during pregnancy (p < 0.0001). In multivariable proportional hazards models urinary stone disease during pregnancy (hazards ratio 12.8, 95% confidence interval [11.8-13.8]) was independently associated with a higher hazard of urinary stone disease after pregnancy. Conclusion: Women with urinary stone disease during pregnancy were more likely to present with recurrent urinary stone disease after pregnancy. Given the one in eight chance of needing further care, women with history of stone disease during pregnancy may benefit from risk counseling, surveillance, or secondary prevention efforts in the postpartum period.

Evaluation of the Educational Impact of the Urology Collaborative Online Video Didactics Lecture Series.

OBJECTIVE: To assess the impact of the Urology Collaborative Online Video Didactic (COViD) lecture series series on resident knowledge as a supplement to resident education during the coronavirus disease 2019 pandemic. METHODS: One hundred thirty-nine urology residents were voluntarily recruited from 8 institutions. A 20-question test, based on 5 COViD lectures, was administered before and after watching the lectures. Pre- and posttest scores (percent correct) and score changes (posttest minus pretest score) were assessed considering demographic data and number of lectures watched. Multiple linear regression determined predictors of improved scores. RESULTS: Of residents recruited, 95 and 71 took the pre- and posttests. Median number of lectures watched was 3. There was an overall increase in correct scores from pretest to posttest (45% vs 57%, P < .01). Watching any lectures vs none led to higher posttest scores (60% vs 44%, P < .01) and score changes (+16% vs +1%, P < .01). There was an increase in baseline pretest scores by post-graduate year (PGY) (P < .01); however there were no significant differences in posttest or score changes by PGY. When accounting for lectures watched, PGY, and time between lecture and posttest, being a PGY6 (P = .01) and watching 3-5 lectures (P < .01) had higher overall correct posttest scores. Watching 3-5 lectures led to greater score changes (P < .001-.04). Over 65% of residents stated the COViD lectures had a large or very large impact on their education. CONCLUSIONS: COViD lectures improved overall correct posttest scores and increased knowledge base for all resident levels. Furthermore, lectures largely impacted resident education during the coronavirus disease 2019 pandemic.

Postoperative opioid-free ureteroscopy discharge: A quality initiative pilot protocol.

BACKGROUND: Opioids are commonly prescribed after ureteroscopy. With an increasing adoption of ureteroscopy for management of urolithiasis, this subset of patients is at high risk for opioid dependence. We sought to pilot an opioid-free discharge protocol for patients undergoing ureteroscopy for urolithiasis. MATERIALS AND METHODS: A prospective cohort study was performed of all patients undergoing ureteroscopy for urolithiasis and compared them to a historical control group. An opioid-free discharge protocol was initiated targeting all areas of surgical care from June 20th, 2019 to September 20th, 2019 as part of an institutional quality improvement initiative. Demographic and surgical data were collected as were morphine equivalent doses (MEDs) prescribed at discharge, postoperative measures including phone calls, clinic visits, and emergency room visits for pain. RESULTS: Between October 1st, 2017 and February 1st, 2018, a total of 54 patients who underwent ureteroscopy were identified and comprised the historical control cohort while 54 prospective patients met the inclusion criteria since institution of the quality improvement initiative. There were no statistically significant differences in baseline patient demographics or surgical characteristics between the 2 patient groups. Total 37% of the intervention group had a preexisting opioid prescription versus 42.6% of the control group with no difference in preoperative MED (p = 0.55). The intervention group had a mean MED of 12.03 at discharge versus 110.5 in the control cohort (p ≤ 0.001). At discharge 3.7% of the intervention group received an opioid prescription versus 88.9% of the control group (p < 0.001). Overall, there was no difference in postoperative pain related phone calls (p = 1.0) or emergency room visits (p = 1.0). CONCLUSIONS: An opioid-free discharge protocol can dramatically reduce opioid prescription at discharge following ureteroscopy for urinary calculi without affecting postoperative measures such as phone calls, clinic visits, or subsequent prescriptions.

Evaluation of Patient Treatment Preferences for 15 to 20 mm Kidney Stones: A Conjoint Analysis.

Introduction and Objective: Ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) are standard treatments for intermediate-size (15-20 mm) kidney stones but differ in their postoperative recovery, stone-free rates, and complication risks. We aimed to evaluate what affects patient treatment preferences. Methods: Patients with urinary stone disease completed a choice-based conjoint analysis exercise assessing four treatment attributes associated with URS and PCNL. A sensitivity analysis using a market simulator was performed, and the relative importance of each attribute was calculated. Differences in treatment preferences by demographic subgroup were assessed. Results: A total of 58 patients completed the conjoint analysis exercise. Stone-free rate was the most important treatment attribute, while the length of hospital stay and cosmesis were less important. Overall, sensitivity analysis based on market simulation scenarios predicted an almost equal preference for URS (52.4%) compared with PCNL (47.6%) for treatment of an intermediate-size stone. Older patients (>65 years old) expressed their stronger preferences for lower infection rates and shorter hospital stays, and were more likely to prefer URS (67.2%, 95% confidence interval [CI]: 52% to 82.5%) compared with younger patients (20-34 years old) (20.3%, 95% CI: 0% to 41.5%) who preferred higher procedure success rates and fewer repeat procedures. Conclusion: Conjoint analysis predicts nearly equal patient preference for URS or PCNL for the treatment of intermediate-size kidney stones. Older patients prefer the lower urinary tract infection risk and shorter hospital stay associated with URS, while younger patients prefer higher stone-free rates associated with PCNL. These results can help guide urologists in counseling patients and improve the shared decision-making process.

Efficacy of three BCG strains (Connaught, TICE and RIVM) with or without secondary resection (re-TUR) for intermediate/high-risk non-muscle-invasive bladder cancers: results from a retrospective single-institution cohort analysis.

PURPOSE: (I) To evaluate the clinical efficacy of three different BCG strains in patients with intermediate-/high-risk non-muscle-invasive bladder cancer (NMIBC). (II) To determine the importance of performing routine secondary resection (re-TUR) in the setting of BCG maintenance protocol for the three strains. METHODS: NMIBCs who received an adjuvant induction followed by a maintenance schedule of intravesical immunotherapy with BCG Connaught, TICE and RIVM. Only BCG-naïve and those treated with the same strain over the course of follow-up were included. Cox proportional hazards model was developed according to prognostic factors by the Spanish Urological Oncology Group (CUETO) as well as by adjusting for the implementation of re-TUR. RESULTS: n = 422 Ta-T1 patients (Connaught, n = 146; TICE, n = 112 and RIVM, n = 164) with a median (IQR) follow-up of 72 (60-85) were reviewed. Re-TUR was associated with improved recurrence and progression outcomes (HRRFS: 0.63; 95% CI 0.46-0.86; HRPFS: 0.55; 95% CI 0.31-0.86). Adjusting for CUETO risk factors and re-TUR, BGC TICE and RIVM provided longer RFS compared to Connaught (HRTICE: 0.58, 95% CI 0.39-0.86; HRRIVM: 0.61, 95% CI 0.42-0.87) while no differences were identified between strains for PFS and CSS. Sub-analysis of only re-TUR cases (n = 190, 45%) showed TICE the sole to achieve longer RFS compared to both Connaught and RIVM. CONCLUSION: Re-TUR was confirmed to ensure longer RFS and PFS in intermediate-/high-risk NMIBCs but did not influence the relative single BCG strain efficacy. When routinely performing re-TUR followed by a maintenance BCG schedule, TICE was superior to the other strains for RFS outcomes.

Safety and Feasibility of Outpatient Surgery in Benign Prostatic Hyperplasia: a Systematic Review and Meta-Analysis.

Purpose: Most of the endourologic procedures along the urinary tract have been widely practiced as outpatient operations, including surgery for benign prostatic hyperplasia (BPH). This systematic review and meta-analysis was conducted to assess safety and feasibility of outpatient surgery for patients suffering from symptomatic BPH candidate for endoscopic disobstruction. Materials and Methods: PubMed, Web of Science, Cochrane, and Embase were searched up until March 30, 2020. Methodological index for nonrandomized studies (MINORS) tool was utilized to assess the quality of included studies, and a pooled measure of failure rate (FR) or event rate (ER) estimate was calculated. Further sensitivity analysis, subgroup analysis, and meta-regression were conducted to investigate contribution of moderators to heterogeneity. Results: Twenty studies with a total of 1626 patients treated according to outpatient criteria for endoscopic BPH surgery were included. In total, 18 studies reporting data on immediate hospital readmission and/or inability to discharge after endoscopic procedure presented FR estimates ranging from 1.7% to 51.1%. Pooled FR estimate was 7.8% (95% confidence interval [CI]: 5.2-10.3); Heterogeneity: Q = 76.85; degree of freedom = 17, p < 0.001; I2 = 75.12%. Subgroup analysis according to surgical technique revealed difference among the three approaches with pooled FR of 3% (95% CI: 1-4.9), 7.1% (95% CI: 3.9-10.4), and 11.8% (95% CI: 7-16.7) for transurethral resection of the prostate, Green-light, and holmium laser vaporesection, respectively (p < 0.001). At meta-regression analysis, none of the retrieved covariates was able to significantly influence the cumulative outcomes reported. ER for postoperative complications and early outpatient visit showed a pooled estimate of 18.6% (95% CI: 13.2-23.9) and 7.7% (95% CI: 4.3-11), respectively. Conclusions: Our analysis revealed how transurethral procedures for BPH on an outpatient setting are overall reliable and safe. Of note, there were significant outcome differences between groups with regard to type of surgical procedure, perioperative prostate volume, and discharge protocol suggesting the need for further prospective analysis to better elucidate the best strategy in such outpatient conduct.

The Impact of Early Exposure to Urology: Evaluation of an Introductory Preclinical Course.

INTRODUCTION: Early exposure in medical school can increase student interest in urology. The majority of medical students graduate without completing a clinical rotation in this field. The primary objectives of our study were to increase exposure to urology and to facilitate interactions between preclinical students and department faculty. METHODS: A 7-week urology curriculum consisting of a weekly 1-hour class was introduced into the M.D. curriculum. Lectures were taught by faculty, fellows and resident physicians, and focused on the professional trajectory of the speaker, a career in urology, information on urological subspecialties and teaching points relevant to each topic. Pre/post surveys were administered to evaluate the effectiveness of the course. RESULTS: A total of 16 students enrolled in the course. Before this course the majority of students had less than 1 hour of teaching focused on urological topics. Informal exposure to urology was similar between preclinical students and graduating fourth year medical students (p >0.05). Post-course surveys showed that students had increased exposure to urology, greater opportunity to interact with residents, fellows and faculty, and overall they were satisfied with their course experience. Students who attended 4 or more courses reported they understood what a career in urology entails and had acquired the necessary information to decide whether to enroll in a clinical rotation in urology. CONCLUSIONS: This course increased exposure to urology among preclinical students and is a feasible addition to a standard medical school curriculum. Future studies will follow these students longitudinally and determine if this course increases student enrollment in urological clinical rotations and increases urology residency applications.

Ultra-Low-Dose CT: An Effective Follow-Up Imaging Modality for Ureterolithiasis.

Background and Purpose: Classically, abdominal X-ray (KUB), ultrasound, or a combination of both have been routinely used for ureteral stone surveillance after initial diagnosis. More recently, ultra-low-dose CT (ULD CT) has emerged as a CT technique that reduces radiation dose while maintaining high sensitivity and specificity for urinary stone detection. We aim to evaluate our initial experience with ULD CT for patients with ureterolithiasis, measuring real-world radiation doses and stone detection performance. Methods: We reviewed all ULD CT scans performed at the Veterans Affairs Palo Alto Health Care System between 2016 and 2018. We included patients with ureteral stones and calculated the mean effective radiation dose per scan. We determined stone location and size, if the stone was visible on the associated KUB or CT scout film, and if hydronephrosis was present. We performed logistic regression to identify variables associated with visibility on KUB or CT scout film and hydronephrosis. Results: One hundred eighteen ULD scans were reviewed, of which 50 detected ureteral stones. The mean effective radiation dose was 1.04 ± 0.41 mSv. Of the ULD CTs that detected ureterolithiasis, 38% lacked visibility on KUB/CT scout film and had no associated hydronephrosis, suggesting that they would be missed with a combination of KUB and ultrasound. Larger stones (odds ratio [OR]: 1.40, 95% confidence interval [CI]: 1.08, 1.96 for every 1 mm increase in stone size) were more likely to be detected by KUB/CT scout film or ultrasound, while stones in the distal ureter (OR: 0.18, 95% CI: 0.03, 0.81) were more likely to be missed by KUB/CT scout film or hydronephrosis. Conclusions: Based on our institutions' initial experience, ULD CT detects small and distal ureteral stones that would likely be missed by KUB or ultrasound, while maintaining a low effective radiation dose. An ULD CT protocol should be considered when reimaging for ureteral stones is necessary.

Capturing the Perspective of Prospective Urology Applicants: Impacts of COVID-19 on Medical Education.

OBJECTIVE: To capture the perspective of prospective urology applicants experiencing unique challenges in the context of COVID-19. METHODS: A voluntary, anonymous survey was distributed online, assessing the impact of COVID-19 on a large sample of US medical students planning to apply to urology residencies. Themes of (1) specialty discernment, (2) alterations to medical education, and (3) the residency application process were explored. RESULTS: A total of 238 medical students, 87% third and fourth years, responded to the survey. While 85% indicated that the pandemic had not deterred their specialty choice, they noted substantial impacts on education, including 82% reporting decreased exposure to urology. Nearly half of students reported changes to required rotations and 35% reported changes to urology-specific rotations at their home institutions. Students shared concerns about suspending in-person experiences, including the impact on letters of recommendation (68% "very concerned) and program choice (73% "very concerned"). Looking to the possibility of virtual interactions, students identified the importance of small group and one-on-one communication with residents (83% "very important") and opportunities to learn about hospital facilities (72% "very important"). CONCLUSION: Despite the impacts of COVID-19 on medical education, prospective urology applicants appear to remain confident in their specialty choice. Students' biggest concerns involve disruption of away rotations, including impacts on obtaining letters of recommendation and choosing a residency program.

Postoperative vacuum therapy following AMS™ LGX 700® inflatable penile prosthesis placement: penile dimension outcomes and overall satisfaction.

Penile shortening after inflatable penile prosthesis for erectile dysfunction is a common postoperative patient complaint and can reduce overall satisfaction with the procedure. In this prospective study we report our results regarding penile dimensions and patient satisfaction outcomes after 1 year of follow-up from AMS™LGX700® penile prosthesis implant with 6 months of vacuum erectile device therapy. Seventy-four selected patients with medically refractory erectile dysfunction underwent AMS™ LGX 700® IPP placement. Postoperatively, patients were assigned vacuum device therapy for 5 min twice daily. Follow-up continued for 1 year after surgery. Dimensional and functional results were assessed. Baseline median preoperative stretched penile length and girth were 14 cm (range 10-17) and 9 cm (range 7-12), respectively. At the end of the study penile median dimensional outcomes were 17 cm (range 13-23) for length and 11 cm (range 10-13) for girth while a median number of 24 pumps (range 18-29) to fully inflate the device was seen. Baseline median International Index of Erectile Function (IIEF-5) score was 9 (range 5-11), at 6 months 20 (range 18-26) and at 1 year was 25 (range 20-27) (p < 0.0001). Median Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) score at the end of the follow-up was 74 (range 66-78). Our postoperative rehabilitation program is feasible and should be recommended after prothesis surgery in order to increase overall satisfaction with the procedure. Penile postoperative dimensional outcomes were statistically significant improved and complications were negligible.

Urinary Stone Disease in Pregnancy: Current Management Practices in a Large National Cohort.

OBJECTIVE: To define current national practice patterns of imaging modalities and urologic procedures in pregnant women with urinary stone disease. METHODS: Using the IBM MarketScan national insurance claims database, we identified pregnant women with urinary stone disease and their corresponding gestational age between 2011 and 2016 using administrative claims data. We then assessed each encounter for urinary stone disease or stone-related urologic procedure during their pregnancy. We abstracted demographic information as well as codes for stone procedures and imaging. RESULTS: We identified 14,298 pregnant women with urinary stone disease during the study period. Of the 12,315 undergoing abdominal imaging (86.1%), magnetic resonance imaging was used in 2.8%, x-ray in 9%, and ultrasound in 74.3%. Computed tomography was not used as a diagnostic modality during pregnancy. Procedural intervention was performed in 749 women (5.2%): 476 (3.3%) ureteral stent placement without definitive stone treatment, 93 (0.6%) percutaneous nephrostomy placement, and 180 (1.3%) ureteroscopy (URS) for definitive stone treatment. URS was most commonly performed before 34 weeks gestation with only 27 cases (15%) performed after. CONCLUSION: This large national cohort reveals the current imaging and procedural practice patterns for urinary stone disease during pregnancy and provides a critical baseline as these practice patterns evolve in the future.

Multi-Institutional Collaborative Resident Education in the Era of COVID-19.

INTRODUCTION: The 2019-2020 coronavirus pandemic has had a significant impact on all aspects of health care. Decrease in clinical and operative volume and limitations for conferences has drastically decreased educational opportunities for resident trainees. We describe the formation and initial success of the Collaborative Online Video Didactics lecture series, a multi-institutional online video didactics collaboration. METHODS: Zoom data extraction and postlecture evaluation surveys were used to collect data on the impact of the pandemic on local educational activities as well as feedback about the lecture series. Lectures are being given by faculty from 35 institutions. The twice daily, hour-long webinar averages more than 470 live viewers per session with an average of 33.5 questions per session and has over 7,000 YouTube views of the recordings after the first 2 weeks. RESULTS: Viewers reported significant decreases in outpatient (75.2%), inpatient (64.9%) and operating room (77.7%) volumes at local programs, and only half (52.7%) of the survey responders indicated an increase in didactics locally. The lectures have been well-received, with over 90% of respondents giving the lecturers and series above average or excellent ratings. A significant majority of responders indicated that the lecture series has allowed for ongoing education opportunities during the pandemic (95.0%), helped to access faculty experts from other institutions (92.3%) and provided a sense of community connectedness during this period of social isolation (81.7%). CONCLUSIONS: We strongly encourage other institutions and trainees to participate in the didactic series and hope that this series can continue to evolve and be of benefit beyond the pandemic.

Pathological outcomes of candidates for active surveillance of prostate cancer.

PURPOSE: Active surveillance of prostate cancer has emerged as a viable treatment option for men with features of low risk disease. Five prospective studies have enrolled patients for active surveillance with varying inclusion criteria. We evaluated the pathological outcomes of men meeting published criteria for active surveillance who elected immediate radical prostatectomy to assess the risk of under grading and under staging in candidates for active surveillance. MATERIALS AND METHODS: Data were extracted from our institutional urological oncology database for all men who underwent radical prostatectomy between 1996 and 2007. The primary outcome was pathological up staging, defined as the occurrence of extracapsular extension or seminal vesicle involvement. Pathological upgrading was identified as a secondary outcome. We determined the proportion of men who would have qualified for each published active surveillance study and the respective rates of upgrading and up staging in each group. RESULTS: We identified 1,097 men who underwent radical prostatectomy with a mean age of 59 years. Overall 28% of the men experienced a Gleason upgrade, 21% had extracapsular extension and 11% had seminal vesicle involvement. In men qualifying based on published active surveillance inclusion criteria, rates of upgrading varied between 23% and 35%, the incidence of extracapsular extension ranged from 7% to 19% and seminal vesicle involvement ranged from 2% to 9%. CONCLUSIONS: Varying entry criteria for active surveillance show different rates of adverse pathological features at radical prostatectomy. Predictably fewer men met the more stringent criteria but these men had a lower incidence of seminal vesicle involvement and extracapsular extension. Such data can be used to advise men of the risks of active surveillance.
