Abstract
BACKGROUND: Bulbar urethral stricture is a common cause for urinary symptoms in men and its two main treatment options both have drawbacks with little evidence on their relative cost-effectiveness. Current guidelines on the management of recurrent bulbar urethral stricture have been predominantly based on expert opinion and panel consensus. OBJECTIVE: To assess the relative cost-effectiveness of open urethroplasty and endoscopic urethrotomy as treatment for recurrent urethral stricture in men. METHODS: Set in the UK National Health Service with recruitment from 38 hospital sites, a randomised controlled trial of open urethroplasty and endoscopic urethrotomy with 6-monthly follow-up over 24 months was conducted. Two hundred and twenty-two men requiring operative treatment for recurrence of bulbar urethral stricture and having had at least one previous intervention for stricture were recruited. Effectiveness was measured by quality- adjusted life years (QALYs) derived from EQ-5D 5L. Cost-effectiveness was measured by the incremental cost per QALY gained over 24 months using a within trial analysis and a Markov model with a 10-year time horizon. RESULTS: In the within trial, urethroplasty cost on average more than urethrotomy (cost difference: £2148 [95% CI 689, 3606]) and resulted in a similar number of QALYs on average (QALY difference: - 0.01 [95% CI - 0.17, 0.14)] over 24 months. The Markov model produced similar results. Sensitivity analyses using multiple imputation, suggested that the results were robust, despite observed missing data. CONCLUSIONS: Based on current practice and evidence, urethrotomy is a cost-effective treatment compared with urethroplasty. KEYPOINTS: Urethrotomy and urethroplasty both led to symptom improvement for men with bulbar urethral stricture-a common cause for urinary symptoms in men; Urethroplasty appeared unlikely to offer good value for money compared to urethrotomy based on current evidence.
