This has led to some concern that residents are not prepared for independent practice after residency. In this study, we held a surgical training session in the WVU Fresh Tissue Training Program (FTTP), which utilizes perfused fresh human cadavers (PFHCs). The goal of this study was to determine if the simulation had a positive effect on urology residents’ confidence in performing open and endoscopic procedures. Materials &Methods: Urology residents participated in a surgical training session in the WVU FTTP, which consisted of performing different urologic procedures (open and endoscopic) on perfused fresh human cadavers (PFHC). Residents were given a survey to rate their confidence in different urologic procedures before and after the session. Each procedure on the survey had 3-6 questions associated with it, with scores ranging from 0 (no confidence) to 4 (great confidence). The total scores for each procedure before and after the session were compared using a nonparametric analysis. We then compared scores for junior residents (PGY1- PGY3) only. Results: Six residents participated in the session. There was a significant increase in the overall total score for every procedure performed after the session (p < 0.05), with the exception of ureteroscopy (p = 0.113). When comparing total scores of the junior residents, there was a significant increase in score for every procedure performed. All residents reported higher levels of confidence after the simulation. Conclusions: PFHCs offer an excellent opportunity to teach a wide variety of urologic procedures to residents. Incorporation of PFHCs may be very useful in urologic training, and further studies on its use are warranted. Quantifying Glans Width Changes With and Without Testosterone in Patients Undergoing Hypospadias Repair S. Mittal 1 ; S. Christianson 1,2 ; N. Hyacinthe 1 ; C. Tan 1 ; D. Weiss 1 ; J.

Understanding its effects on glans size is essential to understanding its efficacy. Our hypothesis was that T preoperatively increases GW measured at surgery. Our goal was to quantify the change with and without T prior to surgery. Materials & Methods: Our database was queried to identify patients who underwent hypospadias surgery from2015-2019, inwhich data for T administration and glans measurements were available. Descriptive, nonparametric and categorical statistics were performed. Results: 648 patients were eligible for analysis. Median age at surgery was 0.9 years (IQR 0.6-1.7). 200/648 (31.3%) patients received T. The median GWat surgery was 15 mm (IQR 13-17). When comparing patients who had T administered to those that did not, we found a significant difference in GW at surgery (16 mm vs. 14 mm, p < 0.001) [Table 1]. The median change in GW preoperatively to surgery was 4 mm for those receiving T vs. -1 mm for those not receiving T (p < 0.001). We observed a trend toward significance of increased administration of T for first- and second-stage repairs (p = 0.062) and concordantly a higher proportion of proximal hypospadias patients received T (p = 0.003). We identified a greater change in GW from preoperative to intraoperative measurements in patients who received two doses of T vs. one dose (4 mm vs. 2 mm, p < 0.001) [Table 2]. Conclusions: In our large, prospectively collected cohort of patients undergoing hypospadias surgery, we were able to quantitate the GW change frompreoperative testosterone. Two doses of testosterone resulted in a significant increase in glans width vs. one dose. RPE-08 5
