Abstract
INTRODUCTION: The objective was to analyze patterns of injury, management, imaging, and follow-up care of renal trauma at a Swiss level 1 trauma center. METHODS: We examined 138 patients (>16 years) with renal organ injuries who presented to our institution between January 2008 and March 2018. Data on demographics, patterns of injury, clinical presentation, management, and follow-up were recorded. RESULTS: The injury grade of the 142 injured kidneys was grade 1 in 25% (n = 36), grade 2 in 16% (n = 23), grade 3 in 32% (n = 46), grade 4 in 24% (n = 34), and grade 5 in 2% (n = 3). The predominant injury mechanism was winter sports (45%). Conservative management was successful in all grade 1 renal injuries, and 91%, 86%, 35%, and 33% of grade 2, 3, 4, and 5 injuries, respectively. Early follow-up with CT or MRI scan was performed in 23% of grade 1-3 injuries and 57% of grade 4-5 injuries with clinical signs of complications as the most frequent indication for grade 1-3 injuries and routine follow-up imaging for grade 4-5 injuries, respectively. In follow-up care (1-9 months after injury) imaging showed persistent pathologies in 39% of grade 1-3 renal injuries and 62% of grade 4-5 injuries. CONCLUSIONS: Most minor renal injuries (grade 1-3) can be successfully managed conservatively. Early follow-up imaging is indicated for patients showing clinical signs of complications. Routine repeat imaging may not be justified for high-grade renal injuries without clinical symptoms. Re-imaging in follow-up care still lacks evidence-based recommendations.
