Background The purpose of this study was to determine the difference in complication rates between males and females undergoing reverse shoulder arthroplasty for proximal humerus fractures. We hypothesized that (1) females were more likely to undergo reverse shoulder arthroplasty for fracture, and (2) males were more likely to sustain a perioperative complication. Methods The National Surgical Quality Improvement Program database was queried to identify patients who underwent reverse shoulder arthroplasty for proximal humerus fracture between 2011 and 2018. Patients were stratified based on biological sex. Patient demographics, comorbidities, and 30-day perioperative complication rates were collected. Univariate analyses and multiple variable logistic regression modeling were performed. Results About 905 patients were included in the analysis—175 (19.3%) were male and 730 (80.7%) were female. Males were more likely to sustain perioperative complications (26.3% vs. 14.1%; P < .001)—pneumonia (2.9% vs. 0.5%; P = .016), unplanned intubation (2.3% vs. 0.4%; P = .029), and unplanned reoperation (9.1% vs. 1.1%; P < .001). On multivariate analysis, males were at a 2.4-fold increase risk of developing any complication (OR = 2.38 [95% CI 1.55-3.65]; P < .001) and a 10-fold increase risk of returning to the operating room for an unplanned reoperation (OR = 10.59 [95% CI 4.23-27.49]; P < .001) compared with females. Conclusion Females were more likely to undergo reverse shoulder arthroplasty for proximal humerus fracture, but males were at increased risk of sustaining short-term complications. This study provides useful information for clinicians to consider when counseling their patients during the perioperative period.

Purpose: We evaluated if scores generated by the LSE classification system and the Urethral Stricture Score system are associated with intraoperative surgical complexity and stricture recurrence risk. Materials and Methods: We retrospectively reviewed all consenting patients who underwent single-stage anterior urethroplasty by a single surgeon at 2 institutions. Urethral Stricture Score and a numerical LSE "score" was calculated for each patient. Pearson's correlation and linear regression analyses were used to assess for a relationship between increasing Urethral Stricture Score and LSE score and surgical complexity. Kaplan-Meier curves and Cox proportional hazard regression models were used to assess for an association between Urethral Stricture Score and LSE score and stricture recurrence risk. Results: A total of 187 patients with a mean age of 48 years (SD 16) and mean stricture length of 4.2 cm (SD 3.3) were included. Mean follow-up was 21 months. Forty-six patients recurred over time. We found a strong positive linear correlation between Urethral Stricture Score and LSE score (P < .001). Both increasing Urethral Stricture Score and LSE score independently linearly correlated with increasing surgical complexity (both P < .0001). Univariable analysis demonstrated that increasing LSE score was significantly associated with an increased risk of stricture recurrence (HR 1.2, P [ .02) but Urethral Stricture Score was not. Patients with a high LSE score (7) were nearly 3 times as likely to recur versus patients with a low LSE score (HR 2.7, P [ .001). Conclusions: Increasing Urethral Stricture Score and LSE score are both associated with increasing surgical complexity, but only LSE score is associated with stricture recurrence risk. Conversion of the LSE classification system into a numeric score adds functionality to this novel system.

between 2004 to 2019 with resident involvement. The cases were stratified by resident involvement: attending as primary (AP), attending and resident (AR), resident as primary (RP).RESULTS: 127,757 urology cases were identified from 2004 to 2019. The most frequent surgeries were transurethral resection of prostate (TURP); transurethral resection of small, medium, or large tumor (TURBT); GreenLight laser of prostate (GLL); hydrocelectomy; and ureteral stent placement. These procedures accounted for 76.5% of all cases. The percentage of RP cases decreased from 31.3% of cases to 18.6%. Reduction in RP cases was seen in all seven top urology cases, particularly in ureteral stent placement which has declined from 44% RP in 2004 to 18% in 2019. Cases with resident involvement had patients with more cardiovascular, pulmonary, and infectious comorbidities. Mean operative times in all cases were not significantly different. The 30-day composite complications and 30-day return to operating room were greatest for AR. Postoperative complications of bleeding, infection, DVT, embolism, renal failure, wound dehiscence, and 30 day all-cause mortality were not significantly different.CONCLUSIONS: Urology resident autonomy has decreased within the VA healthcare system over the past 15 years. Mean operative times and postoperative complications are not inferior in cases that involve residents as the primary surgeon. Increased focus on resident education and surgical autonomy in the operating theater is vital for training the next generation of surgeons.

sacrificed at 45 days post-injury. Urethral tissues were harvested and subjected to immunostaining (VerhoeffeVan Gieson; VVG) for elastin. Results were then validated in human urethral scar tissues (n[3) obtained from patients undergoing urethroplasty. RESULTS: RUG findings are summarized in the Fig C. The RUGs performed showed a significant increase in stricture severity after balloon dilation (Fig C -bottom panel). The methodology utilized in the animal model was confirmed fluoroscopically to be replicable. VVG showed strong labeling for elastin (Fig E-F; black stain; yellow arrows) in rabbit and human (Fig G) scar tissues relative to controls (Fig D).CONCLUSIONS: Our findings confirm that this approach is a viable model to study transurethral intervention induced fibrogenesis. It further supports our hypothesis that urethral wall stretch worsens stricture severity due to elastin degradation. This may be an initiating factor in tissue remodeling after injury. Targeting elastin using an elastase may be a potential pharmacological intervention to treat or prevent stricture recurrence after transurethral interventions.
