ABSTRACT
OBJECTIVES: (1) Assess risk factors associated with urethral stricture recurrence (USR). (2) Assess urethral stricture recurrence after end-to-end urethroplasty (EE) and buccal mucosal graft urethroplasty (BMG). SUBJECTS AND METHODS: A total of 29 males with urethral stricture who underwent either an end-to-end urethroplasty or a buccal mucosal graft urethroplasty were included in this study and followed for 18 months. The association between risk factors and stricture recurrence was assessed. RESULTS: Overall mean patient age was 51.69 ± 14.22 years, time to recurrence was 3 months (IQR: 1-6.25), and stricture length was 2.57 ± 1.30 cm. Important risk factors for USR were stricture length ⩾ 2 cm (p = 0.024), older age (p = 0.042), BMI > 25 kg/m2 (p = 0.021), Qmax after catheter removal <15 ml/s (χ2 = 14.87 p ⩽ <0.001) and previous urethral procedures adjusted for re-do BMG urethroplasty (χ2 = 6.10, p = 0.021). End-to-end urethroplasty showed less USR than BMG, however, these differences were not statistically significant (41.6% vs 22.2%, respectively, p ⩾ 0.05). CONCLUSIONS: Stricture length, age, BMI, and previous urethral procedures predict USR, furthermore, an initial Qmax after catheter removal is an objective measure predictive of USR. There's no difference in USR rate between BMG and EE urethroplasties.
