PURPOSE: The purpose of this multi-institutional study was to compare outcomes of transecting and nontransecting anastomotic bulbar urethroplasty. MATERIALS AND METHODS: We performed a retrospective, multi-institutional review of the records of 352 patients who underwent transecting or nontransecting anastomotic bulbar urethroplasty performed by 1 of 4 reconstructive urologists from September 2003 to March 2017. Study outcomes were urethroplasty success, defined as urethral patency greater than 16Fr on cystoscopy; de novo sexual dysfunction assessed at 6 months, defined as a 5-point or greater change in the SHIM (Sexual Health Inventory for Men) or a patient reported adverse change; and 90-day complications, defined as Clavien 2 or greater. When appropriate, comparisons were made between the transecting and nontransecting cohorts using the Mantel-Cox test, the t-test or the chi-square test. RESULTS: Of the 352 patients with a mean stricture length of 1.7 cm (range 0.5 to 5) 258 and 94 underwent transecting and nontransecting anastomotic bulbar urethroplasty, respectively. The overall success rate was 94.9% at a mean followup of 64.2 months (range 6 to 170). Of the patients 7.1% experienced a 90-day complication and 11.6% reported sexual dysfunction. When comparing transecting and nontransecting techniques, there was no difference in success (93.8% vs 97.9%, Mantel-Cox test p = 0.18) or postoperative complications (8.1% vs 4.3%, p = 0.25). Patients treated with transecting anastomotic urethroplasty were more likely to report an adverse change in sexual function (14.3% vs 4.3%, p = 0.008). On multivariate analysis only transecting urethroplasty was associated with sexual dysfunction (p = 0.01) while age (p = 0.29), stricture length (p = 0.42), etiology (p = 0.99) and surgeon (p = 0.88) were not. CONCLUSIONS: Anastomotic urethroplasty is a highly effective surgery with relatively minimal associated morbidity. Nontransecting anastomotic urethroplasty compares quite favorably to the transecting technique and likely reduces the risk of associated sexual dysfunction.
