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.
