Abstract:

OBJECTIVE: To examine population-based practice patterns and outcomes related to urethroplasty for urethral stricture management. METHODS: We conducted a retrospective study of adult males with urethral stricture disease treated from January 2001 to June 2015 using the Clinformatics Data Mart Database. Treatment was defined as urethral dilation, direct visualized internal urethrotomy, and urethroplasty. We then examined anterior or posterior urethroplasty outcomes defining failure as any subsequent procedure specific to urethral stricture disease occurring > 30 days after urethroplasty. We used multivariable and time-to-event analysis to examine factors associated with failure. RESULTS: We identified 75,666 patients treated for urethral stricture disease, with 420 and 367 undergoing anterior and posterior urethroplasty, respectively. Urethroplasty utilization doubled from 2005 to 2015. One- and 5-year failure rates for anterior and posterior urethroplasty were 25% and 18%, and 40% and 25%, respectively, with median times to failure of 5.1 and 4.1 months. Failures were salvaged primarily with direct visualized internal urethrotomy, with salvage urethroplasty in 19% and 12% of anterior and posterior repairs, respectively. CONCLUSION: Despite increasing population-based urethroplasty utilization over the past decade in our insured cohort, we found higher rates of salvage treatments than reported by high-volume and expert surgeon reports. Further efforts appear warranted to balance workforce expertise and quality of urethroplasty care to meet increasing urethral stricture population needs.
