Objective: To compare limited (only inpatient) venous thromboembolism (VTE) prophylaxis after robot-assisted radical cystectomy (RARC) to limited plus extended prophylaxis. There is little consensus on postoperative VTE prophylaxis regimens after RARC with data mostly extrapolated from other cancers., Methods: Retrospective review of all RARC patients at our center between 2014-2022, identifying two groups: patients after a prospectively implemented protocol (January 2018 to present) utilizing a prolonged 21-day postoperative course of either enoxaparin 40 mg daily or apixaban 2.5 mg twice daily after discharge, or patients prior to January 2018 receiving only limited VTE prophylaxis during their immediate postoperative inpatient stay., Primary Outcome: incidence of symptomatic VTE confirmed with imaging within 90-days postoperatively., Secondary Outcomes: major hemorrhage, complications, readmission, and mortality within 30-days postoperatively. Descriptive statistics depicted baseline patient characteristics, operative information, and complications. Differences were compared between groups. Logistic regression was used to determine associations between variables and primary outcome., Results: Eighty-six patients received limited prophylaxis and 364 received extended prophylaxis. Twelve (2.7%) patients experienced VTE within 90-day postoperatively: (10 [2.7%] extended vs 2 [2.3%] limited, P = .9). Upon stratification into EAU "low-risk" or "high +intermediate-risk" groups, no statistically significant difference in VTE rates was seen between the extended or limited groups. When controlling for prophylaxis regimen, intracorporeal approach was found to be predictive of a lower with a lower risk of VTE (P = .019)., Conclusion: Limited and extended prophylaxis showed no significant differences in VTE rates among RARC patients. Further studies are necessary for RARC patients to improve guidelines., Competing Interests: Declaration of Competing Interest The authors have no conflict of interest to declare., (Copyright © 2024 Elsevier Inc.

Congenital anterior urethral diverticulum (CAUD) is an uncommon abnormality of the male urethra. In the literature, cases of CAUD affecting both children within a set of identical twins or presenting concomitantly with another urethral condition are exceedingly rare. We describe 2 cases of CAUD in identical twins: a pair of newborns in which Twin 1A and Twin 1B both present with CAUD, and a second pair of newborns in which only Twin 2A presents with CAUD along with a partial collateral urethral duplication. In doing so, we aim to add to the incomplete literature on the embryological development of CAUD., (Copyright © 2022 Elsevier Inc. All rights reserved.)
