Herein, we present the longitudinal surgical outcomes data from the Trauma and Urologic Reconstruction Network of Surgeons (TURNS) with the purpose of validating the LSE for outcomes prediction by component subclassifications. METHODS: The TURNS prospective database was used to identify single-stage, non-urethrostomy anterior urethroplasties performed by nine TURNS members between 2008 and 2018. The strictures were retroactively classified using the LSE system and surgical failure was defined as the need for any secondary procedure required for recurrent stricture in the operative field. LSE variables were tested with Kaplan-Meier (KM) survival analysis, assessing for time-dependent success discrimination amongst each subclassification utilizing log-rank testing. RESULTS: A total of 2472 anterior urethroplasties were included in the study. Overall functional success rate at a median follow-up time of 65.1 months (range 7.7. to 172.5) months was 88%. Overall success rates varied significantly by L (94% (L1) to 85% (L3); p <0.001), S (range 93% (S1a) to 81% (S2a); p=0.0005)) and E (range 93% (E1) to 84% (E3c, E6); p <0.0001). KM survival curves for each LSE classification revealed significant time-dependent discrimination within the system components. (Figures 1, 2 and 3 respectively). CONCLUSIONS: Individual LSE components and subclassifications were validated for their ability to predict overall functional outcomes. Urethroplasty techniques can now be compared within individual LSE stricture subtypes with increased precision.
