The long‐term outcome of urethrotomy for primary urethral strictures: a population‐based analysis

Abstract

To determine the long-term outcome of endoscopic urethrotomy for primary urethral strictures based on a population-based approach. We analysed a nationwide database of all patients with urethral stricture disease who underwent endoscopic urethrotomy as a primary intervention between January 2006 and December 2007. All patients were followed individually for 7-9years. Frequencies and types of surgical re-interventions were documented. Repeat surgical interventions were stratified into three treatment types: urethrotomy, urethroplasty, and end-to-end urethral anastomosis. A total of 1203 men underwent urethrotomy during the index period. The median (SD, range) patient age was 63(15.7, 20-85)years. A total of 136 patients (11%) died during follow-up. Within the follow-up period, 932 patients (78%) received no further surgical re-intervention for recurrent disease, and 176 patients (14.6%) required one, 53 (4.5%) two, and 41 (3.4%) three or more procedures. The mean number of re-interventions was 1.5/patient and the lowest re-intervention rate was in patients aged ≥80years (13.9%). In 236 cases (68%) at least one repeat urethrotomy was performed. An open reconstruction was performed in 87 cases (32%), with urethroplasty in 21 patients (24%), and end-to-end anastomosis in 66 patients (76%). The mean interval until re-intervention was 29.5months. This long-term population-based study suggests that the invasive re-treatment rate in men following initial urethrotomy is 22% within 8years and lowest in the advanced age cohort.
