Management of low velocity gunshot wounds to the anterior urethra: the role of primary repair versus urinary diversion alone.
The management of partial transection of the anterior urethra following penetrating penile injuries is controversial. Optional therapeutic techniques range from a primary sutured reapproximation to urinary diversion alone. We recently managed 17 low velocity gunshot wounds to the external genitalia in which the missile traversed the penile corpus cavernosum, and was associated with less than 40% transection of the corpus spongiosum and anterior urethra. Nine patients were managed with suprapubic diversion, skin débridement and corporeal closure along with placement of a urethral catheter. Eight patients were managed by suprapubic diversion, débridement, closure of the corporeal bodies and a primary sutured reapproximation of the anterior urethra. Urethral strictures developed in 7 patients (78%) managed by a suprapubic tube and urethral stenting during an average followup of 20 months (range 18 to 24). In contrast, 1 patient (12%) managed by a sutured urethral approximation had a urethral stricture during an average followup of 20 months (range 18 to 30, p < 0.01). Our data support a significantly better prognosis for partial transection of the anterior urethra secondary to low velocity gunshot wounds if managed by aggressive wound débridement, corporeal repair, placement of a suprapubic catheter and primary repair of the urethra.
