The Efficacy of Primary Interventional Urethral Realignment for the Treatment of Traumatic Urethral Injuries

To evaluate the efficacy of primary interventional urethral realignment (PIUR) in patients with traumatic urethral injuries.

This retrospective study included 13 patients with traumatic urethral injuries who were treated with PIUR between September 2008 and February 2014. All 13 patients were men with the mean age of 56.3 years. Technical success rate of PIUR, time to PIUR, required procedure time, length of hospital stay, duration of urethral catheterization, and complications after PIUR were investigated.

PIUR was technically successful in 12 of 13 patients (92.3%). The mean time from trauma to PIUR was 44 hours (range, 1-240 h). The mean procedure time was 20.2 minutes (range, 3-90 min). The median length of hospital stay was 15 days (range, 1-60 d). The mean duration of urethral catheterization after PIUR was 25 days (range, 9-65 d). There were no immediate complications related to PIUR, although 6 of 12 patients developed symptomatic urethral stricture after PIUR. The mean time to stricture development after PIUR was 4.3 months (range, 2-12 mo). Of the 6 patients, 2 were treated with endoscopic internal urethrotomy, and 4 were treated with interventional radiologic urethral balloon dilation.

PIUR can be safe and effective for patients with traumatic urethral injuries. However, symptomatic stricture formation occurred in one-half of the successful realignment procedures.
