Abstract

Purpose: To present our experience with excision and primary anastomosis (EPA) of radiation-induced urethral strictures (RUS) in men, including risk factors for stricture recurrence and long-term recurrence rates. Methods: A retrospective review was performed of patients who underwent EPA of RUS between 2007 and 2018 at a single tertiary referral center. Demographic information, stricture location and length, complications, and stricture recurrence were analyzed. Univariate and multivariate Cox regression analyses were performed to identify variables impacting recurrence. Results: EPA was performed in 116 patients with RUS. The majority of patients (86.2%, 100/116) underwent at least one prior urologic intervention. Mean stricture length was 2.3 cm. Stricture recurrence occurred in 19.0% (22/116) at a mean of 8.6 months. For patients with at least 1 year of postoperative follow-up (mean 30.7 months), stricture recurrence significantly increased to 36.6% (15/41; p = 0.03). On univariate and multivariate analyses, postoperative complications were associated with stricture recurrence (p < 0.001). Conclusion: EPA remains a viable option for men with RUS. Nearly two-thirds of RUS patients remain recurrence-free with long-term follow-up following EPA.
