Abstract
A total of 74 patients with urethral injury due to external trauma consisted of 48 posterior urethral injuries (25 complete rupture, 23 partial rupture) and 26 anterior urethral injuries (2 complete rupture, 16 partial rupture, and 8 contusion). The diagnosis was made by retrograde urethrography. All 48 patients with posterior urethral injury had associated injuries, including a fractured pelvis in 46, and a mortality rate of 33%. Only 7 of the 26 patients with anterior urethral injury had associated injuries and a mortality rate of 14%. The management of posterior urethral injury is changing from primary realignment of the rupture urethra to suprapubic cystostomy alone and followed later by urethral surgery for the resulting stricture. The impotence rate is significantly lower with management with suprapubic cystostomy alone. However, the type of pelvic fracture, the urethral injury itself disrupting neurovascular structure, and the surgical dissection (initial primary realignment or delayed urethroplasty) must be investigated before it can be determined whether the impotence associated with pelvic trauma is caused by the injury itself or by the surgical dissection undertaken to reconstruct the urethra.
