Abstract
PURPOSE Urinary extravasation is one of the major complications after non-operative management of traumatic renal injury and may lead to urinary tract infection and sepsis. The purpose of this study was to evaluate these factors in patients with traumatic renal injury. METHODS This was a multi-center, retrospective, observational study performed at three tertiary referral hospitals in Osaka prefecture. We included patients with traumatic renal injury transported to the centers between January 2008 and December 2018. We excluded patients who either died or underwent nephrectomy within 24 h after admission. We investigated the occurrence of urinary extravasation and the related factors after traumatic renal injury using multivariable logistic regression analysis. RESULTS In total, 146 patients were eligible for analysis. Their median age was 44 years and 68.5% were male. Their median Injury Severity Score was 17. Renal injuries were graded as American Association for Surgery of Trauma (AAST) grade I in 33 (22.6%), II in 27 (18.5%), III in 38 (26.0%), IV in 28 (19.2%), and V in 20 (13.7%) patients. Urinary extravasation was diagnosed in 26 patients (17.8%) and was statistically significantly associated with AAST grades IV-V (adjusted odds ratio, 33.8 [95% confidence interval 7.12-160], p < 0.001). CONCLUSION We observed urinary extravasation in 17.8% of patients with non-operative management of traumatic renal injury and the diagnosed was made in mostly within 7 days after admission. In this study, the patients with AAST grade IV-V injury were associated with having urinary extravasation.

Abstract
INTRODUCTION The aim of this study was to compare observation and early drainage by ureteral stenting in patients with blunt renal trauma and urinary extravasation. MATERIALS AND METHODS A retrospective national multicenter study was performed including all patients admitted for renal trauma at 17 hospitals between 2005 and 2015. Patients presenting with a urinary extravasation on initial imaging were considered for inclusion. Patients were divided in two groups according to the initial approach: observation vs. early drainage by ureteral stent (within 48 h after admission). The primary endpoint was the persistence of urinary extravasation on follow-up imaging. RESULTS Out of 1799 patients with renal trauma, 238 were included in the analysis (57 in the early drainage and 181 in the observation group). In the early drainage group, 29 patients had persistent urinary extravasation vs. 77 in the observation group (50.9% vs. 42.5%; p value = 0.27). The rates of secondary upper urinary tract drainage did not differ significantly between the early drainage group (26.4%) and the observation group (16%) (p = 0.14). There were no statistically significant differences between the two groups in terms of secondary nephrectomy (0% vs. 2.8%; p = 0.34), and death from trauma (0% vs. 1.8%; p = 0.99). In multivariate analysis, early drainage remained not statistically associated with persistence of urinary extravasation on follow-up imaging (OR = 1.35; p = 0.36) CONCLUSION: In this multicenter cohort, observation was not different from early drainage in terms of persistent urinary extravasation after grade IV blunt renal trauma. Further randomized controlled prospective trials are needed to confirm these findings.
