Efficacy of re-do urethroplasty for post-traumatic urethral stricture: An analysis of the anatomical and functional outcomes.

OBJECTIVES: To investigate the efficacy of re-do urethroplasty for post-traumatic urethral stricture in terms of anatomical and functional outcomes. METHODS: A total of 48 patients who underwent re-do urethroplasty for post-traumatic urethral stricture due to perineal trauma (n = 21) and pelvic fracture urethral injury (n = 27) between October 2010 and March 2020 were retrospectively reviewed. Patients were followed by uroflowmetry, post-void residual volume assessment and 17-Fr flexible cystoscopy after re-do urethroplasty. Successful urethroplasty was defined as having a urethral caliber adequate for the passage of a cystoscope and requiring no additional treatments. Patients completed a validated patient-reported outcome measure for urethral stricture surgery, including overall satisfaction, and the sexual health inventory for men. RESULTS: The type of re-do urethroplasty was anastomotic urethroplasty in 45 (94%) patients and buccal mucosa urethroplasty in three (6%) patients. Urethroplasty was successful in 47 (98%) patients (median follow up 35 months, interquartile range 21-75). The patient-reported outcome measure for urethral stricture surgery and Sexual Health Inventory for Men were assessed in 36 (75%) patients, and the mean lower urinary tract symptom-specific quality of life, EuroQol-5D and EuroQol-visual analog scale scores improved from 2.86, 0.63 and 54.17 preoperatively to 0.78 (P < 0.001), 0.86 (P < 0.001) and 76.94 (P < 0.001) postoperatively, respectively. The pre- and postoperative mean Sexual Health Inventory for Men scores (5.92 and 4.94, respectively) did not significantly differ (P = 0.318). All 36 patients were satisfied with their urethroplasty outcomes, with 20 (56%) very satisfied patients. CONCLUSIONS: Re-do urethroplasty for post-traumatic urethral stricture shows a high success rate and beneficial effects on both anatomical and functional outcomes.
