EducationUrology Residents' Experience and Attitude Toward Surgical Simulation: Presenting our 4-Year Experience With a Multi-institutional, Multi-modality Simulation Model

ObjectiveTo evaluate the Urological resident's attitude and experience with surgical simulation in residency education using a multi-institutional, multi-modality model.Materials and MethodsResidents from 6 area urology training programs rotated through simulation stations in 4 consecutive sessions from 2014 to 2017. Workshops included GreenLight photovaporization of the prostate, ureteroscopic stone extraction, laparoscopic peg transfer, 3-dimensional laparoscopy rope pass, transobturator sling placement, intravesical injection, high definition video system trainer, vasectomy, and Urolift. Faculty members provided teaching assistance, objective scoring, and verbal feedback. Participants completed a nonvalidated questionnaire evaluating utility of the workshop and soliciting suggestions for improvement.ResultsSixty-three of 75 participants (84%) (postgraduate years 1-6) completed the exit questionnaire. Median rating of exercise usefulness on a scale of 1-10 ranged from 7.5 to 9. On a scale of 0-10, cumulative median scores of the course remained high over 4 years: time limit per station (9; interquartile range [IQR] 2), faculty instruction (9, IQR 2), ease of use (9, IQR 2), face validity (8, IQR 3), and overall course (9, IQR 2). On multivariate analysis, there was no difference in rating of domains between postgraduate years. Sixty-seven percent (42/63) believe that simulation training should be a requirement of Urology residency. Ninety-seven percent (63/65) viewed the laboratory as beneficial to their education.ConclusionThis workshop model is a valuable training experience for residents. Most participants believe that surgical simulation is beneficial and should be a requirement for Urology residency. High ratings of usefulness for each exercise demonstrated excellent face validity provided by the course.

Case ReportsRenal Medullary Carcinoma in Patients with Sickle Cell Trait

AbstractRenal medullary carcinoma has recently been described as an aggressive neoplasm affecting young African Americans with sickle cell disease or sickle cell trait. We report the presentation, treatment, and outcome in 3 patients with renal medullary carcinoma along with a description of the unsuccessful treatment attempts. A brief discussion and review of the literature is included.

Original articleClinical—testisMarital status independently predicts testis cancer survival—an analysis of the SEER database

AbstractObjectivesPrevious reports have shown that married men with malignancies have improved 10-year survival over unmarried men. We sought to investigate the effect of marital status on 10-year survival in a U.S. population-based cohort of men with testis cancer.Materials and methodsWe examined 30,789 cases of testis cancer reported to the Surveillance, Epidemiology, and End Results (SEER 17) database between 1973 and 2005. All staging were converted to the 1997 AJCC TNM system. Patients less than 18 years of age at time of diagnosis were excluded. A subgroup analysis of patients with stages I or II non-seminomatous germ cell tumors (NSGCT) was performed. Univariate analysis using t-tests and χ2 tests compared characteristics of patients separated by marital status. Multivariate analysis was performed using a Cox proportional hazard model to generate Kaplan-Meier survival curves, with all-cause and cancer-specific mortality as the primary endpoints.Results20,245 cases met the inclusion criteria. Married men were more likely to be older (38.9 vs. 31.4 years), Caucasian (94.4% vs. 92.1%), stage I (73.1% vs. 61.4%), and have seminoma as the tumor histology (57.3% vs. 43.4%). On multivariate analysis, married status (HR 0.58, P < 0.001) and Caucasian race (HR 0.66, P < 0.001) independently predicted improved overall survival, while increased age (HR 1.05, P < 0.001), increased stage (HR 1.53–6.59, P < 0.001), and lymphoid (HR 4.05, P < 0.001), or NSGCT (HR 1.89, P < 0.001) histology independently predicted death. Similarly, on multivariate analysis, married status (HR 0.60, P < 0.001) and Caucasian race (HR 0.57, P < 0.001) independently predicted improved testis cancer-specific survival, while increased age (HR 1.03, P < 0.001), increased stage (HR 2.51–15.67, P < 0.001), and NSGCT (HR 2.54, P < 0.001) histology independently predicted testis cancer-specific death. A subgroup analysis of men with stages I or II NSGCT revealed similar predictors of all-cause survival as the overall cohort, with retroperitoneal lymph node dissection (RPLND) as an additional independent predictor of overall survival (HR 0.59, P = 0.001), despite equal rates of the treatment between married and unmarried men (44.8% vs. 43.4%, P = 0.33).ConclusionsMarital status is an independent predictor of improved overall and cancer-specific survival in men with testis cancer. In men with stages I or II NSGCT, RPLND is an additional predictor of improved overall survival. Marital status does not appear to influence whether men undergo RPLND.

Health PolicyUrological Malpractice: Claim Trend Analysis and Severity of Injury

AbstractIntroductionIn the current malpractice environment all urologists are at risk. Claim trend data on costs, types of urological errors and severity of injury in urological surgery malpractice claims are lacking.MethodsWe analyzed physician level claim data from a large professional liability insurer with a nationwide client base. Available data included records on closed malpractice claims from 1985 to 2013. We evaluated insured demographics, total number of closed claims, costs of indemnity payments, costs of defense, types of errors resulting in closed claims and severity of injury in urological claims.ResultsCompared to other medical specialties urology ranks 13th in total claims and 15th in average cost of indemnity payments in the last decade. Most urological claims are dropped, dismissed or withdrawn without indemnity payment. Of closed urological claims 27.2% result in an indemnity payment to the plaintiff. Adjusting for inflation, urological indemnity payments have increased by 60% since the 1980s and average payouts are now greater than $350,000. Improper performance of a procedure is the most prevalent urological error resulting in closed claims (875 closed claims in the last decade). Procedures involving the kidney (245 closed claims) and prostate (244 closed claims) are most frequently implicated. The majority of urological errors result in temporary or minor permanent injury. Errors resulting in grave injury are the most costly, with average indemnity payments of $514,844.ConclusionsAwareness of claim trends and errors implicated can help urologists better understand the current malpractice environment.
