Repeat Excision and Primary Anastomotic Urethroplasty for Salvage of Recurrent Bulbar Urethral Stricture.

PURPOSE: We compared the results of initial excision and primary anastomosis urethroplasty to the excision and primary anastomosis outcomes of other challenging reoperative clinical settings, including secondary cases (prior urethroplasty of any technique other than excision and primary anastomosis) and repeat cases (prior excision and primary anastomosis).

MATERIALS AND

METHODS

We reviewed our database of patients who underwent excision and primary anastomosis urethroplasty for bulbar urethral stricture at our tertiary referral center from 2007 to 2014. Patients without available data and those with a history of lichen sclerosus, radiation, pelvic fracture urethral injuries, distal strictures and/or hypospadias were excluded from analysis. Patient characteristics and outcomes were compared between those undergoing initial, secondary, and repeat excision and primary anastomosis urethroplasty for bulbar urethral stricture.

RESULTS

Among 898 urethroplasties performed during the study period we identified 305 men who underwent excision and primary anastomosis urethroplasty of the bulbar urethra, including an initial procedure in 268 of 305 (88%) and reoperation in 37 (12%). Of patients with reoperation 18 of 37 (49%) underwent secondary excision and primary anastomosis following a different type of prior urethroplasty and 19 (51%) underwent repeat excision and primary anastomosis. Repeat excision and primary anastomosis in the bulbar urethra was successful in 18 of 19 patients (95%), which was comparable to the success rate of initial bulbar excision and primary anastomosis (251 of 268 or 94%) as well as secondary bulbar excision and primary anastomosis (17 of 18 or 94%, p = 0.975) with a similar mean stricture length. Mean followup for all patients was 41.5 months (range 6 to 90) and mean followup in each group was greater than 30 months.

CONCLUSIONS

Repeat excision and primary anastomosis urethroplasty has excellent results for short bulbar strictures, comparable to those achieved in the initial and secondary setting.
