RE Re Do urethroplasty after multiple failed surgeries of pelvic fracture urethral injury.

introductionWe quantify surgical success rate in the management of pelvic fracture urethral injury (PFUI) with repeat urethroplasty in the setting of two or more failed prior urethroplasties. MATERIALS AND MATERIALS: A retrospective analysis was completed of a single surgeon urethroplasty database from Jan 1, 2012 to June 31, 2018. Patients with a history of PFUI recurrent urethral stricture despite two or more failed prior urethroplasty procedures were included.

resultsWe identified 87 patients that had two more more failed prior urethroplasties. These had 2 main categories. One requiring anastomotic urethroplasty and other requiring substitution urethroplasty. Total success rate was 74.75% for anastomotic group and 84.61% for substitution group with a median follow-up of 34 months (range 6-60). Overall success rate for re redo Urethroplasty was 82.70%. Bulbar urethral ischemic necrosis was identified in 14 of 64 patients (21.9%). In these cases urethral substitution measures were performed including 12 with preputial flap and tubularization, 1 sigmoid colon substitution, medial thigh flap. No significant difference was observed between the success or failure group with respect to age, BMI, stricture length, number of prior urethroplasty procedure or endoscopic procedures or comorbidities.

conclusionsOur findings demonstrate that high success rates can be achieved for repeat urethroplasty in recurrent PFUI urethral stricture after two or more failed prior urethroplasty procedures. Bulbar urethral ischemic necrosis is a common finding in this patient population. Patients should be managed at a tertiary high volume referral center.
