Abstract

Objective: To review the outcome of bulbar urethroplasty using one-stage surgical techniques. Methods: Of 375 patients, who underwent one-stage bulbar urethroplasties, 165 patients (44%) underwent anastomotic repair (AR), 40 (10.7%) underwent augmented anastomotic repair (AAR) using penile skin grafts (PSGs) or oral mucosal grafts (OMGs), and 170 (45.3%) underwent onlay grafting techniques (OGTs) using PSGs or OMGs. Clinical outcome was considered a failure when any postoperative instrumentation was needed. The χ2 and Fisher's exact test for categorical data were used. The sample size of 375 patients provides a statistical power (1-β) of 99% at α = 0.05; p <0.05 was set as significant. Results: The average follow-up was 53 mo. Of 375 cases, 313 (83.5%) were successful and 62 (16.5%) failures. Of 165 ARs, 150 (90.9%) were successful and 15 (9.1%) failures. Of 40 AARs, 24 (60%) were successful and 16 (40%) failures. Of 170 OGTs, 139 (81.8%) were successful and 31 (18.2%) failures. The AR showed statistically significant higher success rate compared to OGT (p = 0.023) and AAR (p = 0.0001). Of 47 PSGs, 28 (59.6%) were successful and 19 (40.4%) failures. Of 163 OMGs, 135 (82.8%) were successful and 28 (17.2%) failures. This difference was statistically significant (p = 0.002). Conclusions: One-stage bulbar urethroplasties showed an overall 83.5% success rate. The AR showed the higher success rate compared to the OGT or AAR. OMGs (82.8% success rate) perform statistically better than PSGs (59.6% success rate).
