Objective: We studied the surgical outcomes of urethroplasty in our center and the risk factors for recurrent urethral stricture after urethroplasty.
Material and method: We retrospectively reviewed all patients with urethral stricture who underwent urethroplasty in Rajavithi Hospital between January 2008 and December 2014. Recurrent stricture was defined as the need to use postoperative instrumentation. Chi-square test or Fisher exact test was used to assess the significance of risk factors for recurrence.
Result: Mean patient age was 37.8±15.7yr. Mean BMI was 22.1±4.5 kg/m2. The etiology of urethral stricture was trauma (83%). The stricture site was located at anterior urethra (52%) and posterior urethra (43%). Mean stricture length was 1.75±0.92 cm. End-to-end anastomosis was performed in 82%, flap urethroplasty in 17%, and two stage urethroplasty in 1%. Mean operative time was 219.8±68 min. Recurrence occurred in 28% at a mean time of 6.66±12.7 months. Treatments after recurrence were urethral dilation 57.1%, direct visual internal urethrotomy 17.9%, urethroplasty 14.3%, and suprapubic cystostomy 10.7%. We found no association of the risk factors and recurrent stricture in our study.
Conclusion: Recurrence rate after urethroplasty was 28% in our study. Mean time to recurrence was 6.6 months. We found no association of the risk factors and recurrent stricture in our study.
