International audience. PURPOSE: Previous studies suggested better functional outcomes and longer device survival for female artificial urinary sphincter (AUS) implantation compared to male AUS implantation. We hypothesized that the adoption of robotic approaches for female implantation might have influenced these comparisons. This study aimed to compare the outcomes of robotic female AUS and male AUS implantation for non-neurogenic stress urinary incontinence (SUI). METHODS: We retrospectively reviewed charts of male patients who had AUS implantation and female patients who underwent robotic AUS implantation for non-neurogenic SUI between 2010 and 2022 at a single center. Prior AUS implantations were exclusion criteria. The primary endpoint was continence status at 3 months, categorized as complete resolution of SUI (0 pad), improved SUI (1pad), or unchanged SUI (>1pad). RESULTS: After excluding 79 patients, 171 were included: 70 women and 101 men. Operative time was shorter in males (126.9 vs. 165.5 min; p < 0.0001). Postoperative complication rates were similar (17.3% vs. 22.9%; p = 0.38). Continence status at 3 months and last follow-up favored females. The ICIQ-SF decrease at 3 months was greater in females (-7.2 vs. -4.6; p < 0.001). The 5-year estimated explantation-free survival was similar (78.6% vs. 73.7%; p = 0.94) as was the revision-free survival (67.4% vs. 61.7%; p = 0.89). Multivariate analysis showed that female gender was associated with better continence at last follow-up (OR = 4.3; p = 0.03). CONCLUSION: Robotic female AUS implantation is associated with better functional outcomes than male AUS implantation, with similar morbidity and survival rates.
