Background:
To provide a descriptive analysis of scrotal and testicular trauma in the USA. Additionally, we hypothesized that motorcycle collision would have a higher association with scrotal or testicular trauma and subsequent scrotal or testicular operation, compared to a bicycle collision.
Methods: The National Trauma Data Bank (2007–2015) was queried to identify adult male patients with scrotal or testicular trauma. A multivariable logistic regression analysis was performed.
Results: A total of 8,030 patients (0.23%) had scrotal/testicular injury, with 44.6% involved in blunt trauma. A penetrating mechanism occurred in 50.5% of cases, with assault by firearm (75.8%) being the most common. The median age of the patients was 31 years and the median injury severity score was 8. Most had isolated scrotal or testicular trauma (74.5%), with 48.3% requiring scrotal or testicular operation, most commonly repair of laceration (37.3%). Patients involved in a motorcycle collision had higher risk for scrotal/testicular trauma (OR=5.40, CI=4.40–6.61, p=0.0004) and subsequent scrotal/testicular surgery (OR=4.93, CI=3.82–6.36, p=0.0005), compared to bicycle collision.
Conclusion: Scrotal or testicular trauma is rare but occurs most commonly after assault by firearm. Most patients only have isolated scrotal or testicular trauma, but nearly half require subsequent scrotal or testicular operation. Trauma patients presenting after a motorcycle collision have a higher association of scrotal or testicular trauma and subsequent surgery when compared to those involved in a bicycle collision.
