Purpose Although endoscopic realignment has been accepted as a standard treatment for urethral injuries, the long-term follow-up data on this procedure are not sufficient. We report the long-term outcome of primary endoscopic realignment in bulbous urethral injuries. Methods Patients with bulbous urethral injuries were treated by primary endoscopic realignment between 1991 and 2005. The operative procedure included suprapubic cystostomy and transurethral catheterization using a guide wire, within 72 hours of injury. The study population included 51 patients with a minimum follow-up duration of 5 years. Results The most common causes of the injuries were straddle injury from falling down (74.5%), and pelvic bone fracture (7.8%). Gross hematuria was the most common complaint (92.2%). Twenty-three patients (45.1%) had complete urethral injuries. The mean time to operation after the injury was 38.8±43.2 hours. The mean operation time and mean indwelling time of a urethral Foley catheter were 55.5±37.6 minutes and 22.0±11.9 days, respectively. Twenty out of 51 patients (39.2%) were diagnosed with urethral stricture in 89.1±36.6 months after surgery. A multivariate analysis revealed that young age and operation time were independent risk factors for strictures as a complication of urethral realignment (hazard ratio [HR], 6.554, P=0.032; HR, 6.206, P=0.035). Conclusions Urethral stricture commonly developed as a postoperative complication of primary endoscopic urethral realignment for bulbous urethral injury, especially in young age and long operation time.
