Mp35-15 one-Stage Buccal Mucosal Graft Urethroplasty for Secondary Anterior Urethral Strictures Following Failed Primary Hypospadias Repair: 10-Year Experience From a Referral Center

Abstract

95% CI), at 5 years 0.67 (0.56 -0.80, 95% CI). Excluding the Zumstein cohort, recurrence-free rates at 1 yr were 0.95 (0.92 -0.97, 95% CI), at 3 yrs 0.85 (0.79 -0.912, 95% CI), at 5 yrs 0.76 (0.67 -0.86, 95% CI). Zumstein study success rates were worse than the 10 other studies in the literature (p [ .05) and thus bit of an outlier.CONCLUSIONS: Despite early term success of Asopa urethroplasty, there is progressive failure over time. Intermediate term success of AU is worse then the commonly cited 5 yr success for ventral/dorsal grafting (85%). The Asopa technique in adults appears to lack durability. Further studies are needed to elucidate possible causes.
