Urology Consult: Association with Renal Trauma Imaging and Intervention.

OBJECTIVE

To describe rates of urology consultation following renal trauma and assess subsequent impact on imaging and intervention. Renal trauma may be initially managed by either trauma or urologic surgeons alone or collaboratively. Differences in management between the specialties are not well studied.

METHODS

We conducted an IRB-approved retrospective review of patients at a Level I trauma center sustaining renal trauma between 2014 and 2021. Demographic, injury, radiologic, and intervention variables were extracted. Frequencies and medians were compared using chi-squared and Fischer's exact tests or Mann-Whitney U tests, respectively. Analyses were performed using STATA with P <.05 considered significant.

RESULTS

From 2014 to 2021, 118 patients with median age 29 (IQR 22-41) sustained renal trauma. Urology was consulted in 18 (15.3%) cases. Demographic and injury characteristics were similar between the 2 groups. AAST renal injury grade was transcribed in the initial radiologic reports for 49 (41.5%) of patients. Those in the urology consult group were more likely to receive delayed contrast imaging during their admission (50.0% vs 17.0%, P <.01). Among those with high-grade injuries, those with urology consult were less likely to undergo nephrectomy (36.4% vs 78.8%, P = .02).

CONCLUSION

We observed differences in imaging patterns between renal trauma patients who are managed primarily by trauma surgery versus urology. However, the impact of these differences in imaging remains to be elucidated. Among patients with high-grade renal trauma, urology consult was associated with decreased rate of nephrectomy, emphasizing the feasibility of renal salvage in a multidisciplinary trauma setting.
