958 Two-sided dorsal plus ventral oral graft bulbar urethroplasty: Long-term results and predictive factors

942 a 2015 Else All Rights Re throplasty by preserving the narrow urethral plate in tight bulbar strictures and investigate which factors might influence long-term outcomes. METHODS This is a single-center retrospective study of 166 patients who underwent DVOG urethroplasty for tight bulbar strictures by a single surgeon (E.P.) between 2002 and 2013. The strictured urethra was opened ventrally; the exposed urethral plate was incised in the midline and augmented dorsally and ventrally using 2 oral grafts. Outcome was considered a failure when any postoperative instrumentation was needed. According to stricture length, patients were classified in 3 groups as follows: 1.5 cm (group 1), >1.5 and 3.9 cm (group 2), and 4 cm (group 3). Time to failure was analyzed using Kaplan-Meier estimates and Cox regression. RESULTS Median follow-up was 47 months (interquartile range, 33-95.5 months). Of the 166 patients, 149 (89.8%) were successful and 17 (10.2%) were failures. Most of the failures (90%) were observed during the first 5 years of follow-up; afterward, the success rate remained stable. The stricture length was a significant predictor of surgical outcome (odds ratio, 1.743 per cm; confidence interval, 1.2-2.5; P<.001); patients with a urethral stricture 4 cm presented a higher risk of late failure. Age, stricture etiology, and previous treatment were not significant predictors of surgical outcome. CONCLUSION With long-term follow-up, the treatment of tight bulbar strictures using a 2-sided DVOG urethroplasty showed a high success rate. The stricture length is an independent predictor of failure. UROLOGY 85: 942e947, 2015. 2015 Elsevier Inc.
