BACKGROUND:Often secondary to obesity, adult-acquired buried penis (AABP) is an increasingly common condition. AABP is often detrimental to urinary and sexual function, psychological well-being, and quality of life. Surgical treatment involves resection of excess soft tissue, with adjunct procedures, including a panniculectomy. However, few studies have been conducted investigating the risks of panniculectomy in the context of AABP surgical repair. METHODS:A systematic review of PubMed, Embase, and Cochrane databases was performed, following the PRISMA 2020 guidelines. Descriptive statistics regarding patient demographics, complications, and surgical technique were conducted. After this, an analysis of AABP patients within the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was conducted. RESULTS:Four studies including 57 patients reported panniculectomy as part of buried penis repair (PBPR). Surgical approaches included a modified trapezoid and traditional transverse incision. All authors utilized postoperative drains. Dehiscence and wound infection were the most frequent complications. Univariate NSQIP analysis revealed that PBPR patients had higher body mass index, more comorbidities, and greater wound complication rates. Multivariate analysis revealed that PBPR did not significantly increase 30-day complications compared to isolated BPR ( P > 0.05), while body mass index remained a significant predictor. CONCLUSIONS:Surgical repair of AABP can greatly improve patient quality of life. The available literature and NSQIP-based analysis reveal that concurrent panniculectomy in AABP repair has a comparable complication profile. Future studies are necessary to better characterize the long-term outcomes of this PBPR.

OBJECTIVE:To evaluate the incidence of gender-affirming phalloplasty and complications in a large population-based dataset. METHODS:Retrospective cohort study was done using the California Department of Health Care Access and Information datasets which include patient-level data from all licensed hospitals, emergency departments, and ambulatory surgery facilities in California. Adult patients 18 years or older undergoing gender-affirming phalloplasty in California from January 1, 2009 to December 31, 2019 were included. We examined phalloplasty-related complications using International Classification of Disease diagnosis and procedure codes and Current Procedural Terminology codes. Unique record linkage number identifiers were used to follow patients longitudinally. Statistical analysis included Kaplan-Meier survival analysis and Cox proportional hazards analysis. RESULTS:We identified 766 patients who underwent gender-affirming phalloplasty in 23 facilities. Of 475 patients with record linkage numbers, 253 (55.3%) had subsequent re-presentations to the inpatient, emergency department, and ambulatory surgery settings related to phalloplasty complications. Survival analysis indicated that 50% of patients re-presented by 1 year post-phalloplasty. Asian/Pacific Islander patients had lower risk of complications, and California residents had higher risk of complications. CONCLUSIONS:This population-based study confirms that gender-affirming phalloplasty has a high complication rate, and demonstrates for the first time an association with high rates of return to hospitals, emergency departments, and ambulatory centers. These findings provide additional higher-level evidence that may aid patient counseling, shared surgical decision making, and institutional and government policy.

OBJECTIVE:To investigate predictors of surgical success for patients undergoing robotic ureteral reconstruction (RUR) for ureteropelvic junction obstruction, proximal and middle ureteral stricture disease. METHODS:We retrospectively reviewed our multi-institutional Collaborative of Reconstructive Robotic Ureteral Surgery (CORRUS) database to identify all consecutive patients undergoing RUR for UPJO, proximal and/or middle ureteral stricture disease between 04/2012-12/2020. The specific reconstruction technique was determined by the primary surgeon based on clinical history and intraoperative findings. Patients were grouped according to whether they were surgical successful. Preoperative variables between both groups were compared using chi-square tests. All independent variables with associations of p<0.2 then underwent a binary logistic regression analysis to determine predictive variables of success for RUR (p≤0.05 was considered statistically significant). RESULTS:Overall, 338 patients met inclusion criteria. Surgical success rates of RUR are shown in Table 1. Univariate analysis (Table 2) showed that there were a lower proportion of patients with diabetes (8.9% versus 25.7%, p<0.01) and a higher proportion of patients who underwent ureteral rest (74.3% versus 48.6%, p<0.01) in the surgical success group. Multivariate logistic regression analysis (Table 3) further revealed the odds of surgical success in patients without diabetes was 3.08 times (CI 1.26-7.54, p=0.01) the odds of success for patients with diabetes. The odds of surgical success in patients who underwent preoperative ureteral rest were 2.8 times (CI 1.35-5.83, p=0.01) the odds of success for patients who did not undergo preoperative ureteral rest. CONCLUSION/CONCLUSIONS:Surgical success of RUR for management of UPJO, proximal and middle ureteral strictures may be influenced by factors including preoperative ureteral rest and presence of diabetes.
