Gunshot wounds to the scrotum: a large single-institutional 20-year experience.

Unlabelled: Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Penetrating trauma to the scrotum often requires operative intervention, with testicular salvage only possible when enough testicular tissue can be re-approximated in the traumatic setting. The present report represents the largest series of gunshot wound trauma to the scrotum in the literature. Further, it validates recommendations of the European Association of Urology guidelines on urological trauma that advocate operative intervention due to minimal rates of patient morbidity and the inherent limitations of scrotal ultrasonography in discerning testicular compromise.

Objective: To report our 20-year experience of gunshot wounds (GSWs) to the scrotum and outline the management of this traumatic injury.

Patients And Methods: We queried our institutional database for patients presenting with GSWs to the scrotum between 1985 and 2006. All patients underwent the standard trauma evaluation upon presentation, including physical examination of the external genitalia. Management was dictated by the presence or absence of a penetrating injury to the scrotum and associated traumatic injuries. Nonoperative and operative management of traumatic injury to the scrotum were used. Testicular salvage was performed when anatomically feasible. If testicular salvage was not feasible, an orchiectomy was performed.

Results: Scrotal exploration was performed in 91 (94%) patients while six (6%) patients were treated nonoperatively. Testicular injury was found in 44 (48%) patients undergoing exploration, six (7%) of whom had bilateral testicular injuries, which gave a total of 50 injured testicles. Of the injured testicles, 24 (48%) could not be salvaged and required orchiectomy, while 26 (52%) were debrided and repaired. The most common associated genitourinary (GU) injuries were to the corpora cavernosum (n= 20 [21%]) and urethra (n= 10 [10%]). Soft tissue injury of the extremities occurred in 54 patients (56%), representing the most common non-GU-associated injury. Postoperative complications occurred infrequently: one patient (1%) returned for abscess drainage and one (1%) for haematoma evacuation.

Conclusions: The present report confirms that any patient with a penetrating injury to the scrotum should undergo immediate scrotal exploration. A low clinical suspicion for performing additional studies to rule out associated urethral and/or penile injury is clinically warranted. Testicular loss occurs in ≈50% of injured testicles.
