Urology Boot Camp: A Pilot Medical Student Curriculum for Common Bedside Urologic Procedures.

OBJECTIVES: To develop a novel "bootcamp" simulation-based curriculum to introduce common urologic procedures and to improve readiness for performing them at bedside. METHODS: Three hundred twenty-five third-year medical students at our single institution participated in a hands-on simulation "boot camp" over a 2-year accrual period. This curriculum was designed to teach basic urologic bedside procedures (ie, Foley catheter placement, Bladder irrigation) to third year medical students prior to the start of their surgical clerkships in a live instructional setting with direct feedback from instructors. The objective aspects of the study consisted of a survey administered to study participants following participation in the simulation boot camp, as well as pre- and post-module assessments. RESULTS: Medical students self-reported knowledge gains following the simulation session (P < .001), with 45.8% increase in procedural confidence. Additionally, students reported that the educational intervention was beneficial to their understanding of the subject matter (P < .001), were "very likely" to recommend the session to another medical student (P < .001), and felt that educational intervention better prepared them for an upcoming national exam (P < .001). Finally, the greatest gains were seen for those students who self-reported lower precurriculum knowledge (P < .001). CONCLUSIONS: Findings from our M3 "boot camp" led to self-reported gains in subject matter knowledge following the hands-on simulation curriculum, indicating that this type of educational intervention can be beneficial in preparing medical students for common bedside procedures.

The Impact of Ureteral Access Sheath Use on the Development of Abnormal Postoperative Upper Tract Imaging after Ureteroscopy.

PURPOSE: Ureteral access sheaths are commonly used during ureteroscopy to facilitate stone removal, improve visibility and maintain low intrarenal pressures. However, the use of a ureteral access sheath can cause ureteral wall ischemia and ureteral tears, potentially increasing the risk of postoperative ureteral stricture and obstruction. We studied the impact of ureteral access sheath use on postoperative imaging studies. Secondary objectives included studying the impact of other intraoperative parameters on postoperative imaging studies. MATERIALS AND METHODS: A retrospective chart review was conducted of cases that underwent ureteroscopy for nephroureterolithiasis across 2 high volume institutions between January 2012 and September 2016. Patient demographics, cumulative stone size, operative time, use of ureteral access sheath, laser lithotripsy, basket extraction, preoperative ureteral stent and postoperative ureteral stent placement were extracted from the electronic medical record. Findings of followup renal ultrasound, kidney-ureter-bladder x-ray and/or computerized tomography at approximately 8 weeks after surgery were recorded. RESULTS: A total of 1,332 ureteroscopies were performed with 1,060 cases (79.6%) returning for routine upper tract imaging after ureteroscopy. Postoperative hydronephrosis was noted following 127 cases (12.0%). Factors predicting presence of hydronephrosis after ureteroscopy include lower body mass index (p=0.0016), greater cumulative stone size (p=0.0003), increased operative time (p <0.0001), preoperative ureteral stent (OR 1.49, p=0.0299) and postoperative ureteral stent placement (OR 6.43, p=0.0031). Postoperative hydronephrosis was not associated with use of ureteral access sheath, age, laser lithotripsy or basket extraction. CONCLUSIONS: Use of ureteral access sheath did not have a significant impact on development of postoperative hydronephrosis, suggesting ureteral access sheath is safe for use during ureteroscopy. Ureteral strictures remain rare following ureteroscopy, seen in only 1.0% of our cohort. With an observed prevalence of hydronephrosis of 12.0% on followup imaging at 8 weeks, routine upper tract imaging after ureteroscopy remains a valuable prognostic tool.

Evaluation and treatment of an unusual urachal mass: a case report.

Abnormalities of the urachus, the vestigial remnant of the allantois, result when the embryonic lumen fails to completely obliterate during fetal development. In adults, urachal abnormalities are most commonly masses, with urachal adenocarcinoma representing the most frequent etiology. Due to the low incidence of urachal masses, guidelines for diagnostic workup and treatment are based off of a limited body of evidence comprised primarily of case reports and retrospective series. We present the case of a fifty-two-year-old woman with a urachal mass. Full radiologic workup consisting of computed tomography, cystoscopy and ultrasonography is included, and the risk factors, treatment and prognosis are discussed.

Racial disparities in oncologic outcomes after radical prostatectomy: long-term follow-up.

OBJECTIVE: To report race-based outcomes after radical prostatectomy (RP) in a cohort stratified by National Comprehensive Cancer Network (NCCN) risk category with updated follow-up. MATERIALS AND METHODS: Studies describing racial disparities in outcomes after RP are conflicting. We studied 15,993 white and 1634 African American (AA) pretreatment-naïve men who underwent RP at our institution (1992-2013) with complete preoperative and pathologic data. Pathologic outcomes were compared between races using appropriate statistical tests; biochemical recurrence (BCR) for men with complete follow-up was compared using multivariate models that controlled separately for preoperative and postoperative covariates. RESULTS: Very low- and low-risk AA men were more likely to have positive surgical margins (P <.01), adverse pathologic features (P <.01), and be upgraded at RP (P <.01). With a median follow-up of 4.0 years after RP, AA race was an independent predictor of BCR among NCCN low-risk (HR, 2.16; P <.001) and intermediate-risk (hazard ratio [HR], 1.34; P = .024) classes and pathologic Gleason score ≤ 6 (HR, 2.42; P <.001) and Gleason score 7 (HR, 1.71; P <.001). BCR-free survival for very low-risk AA men was similar to low-risk white men (P = .890); BCR-free survival for low-risk AA men was similar to intermediate-risk white men (P = .060). CONCLUSION: When stratified by NCCN risk, AA men with very low-, low-, or intermediate-risk prostate cancer who undergo RP are more likely to have adverse pathologic findings and BCR compared with white men. AA men with "low risk" prostate cancer, especially those considering active surveillance, should be counseled that their recurrence risks can resemble those of whites in higher risk categories.
