Abstract

BACKGROUND: Traumatic kidney injury is an infrequent event with a wide range of injury patterns. The aim of this paper is to review the incidence, mechanisms of injury, diagnostic methods, and therapeutic indications of renal injury according to the most recent evidence and to perform an analysis of mortality rates on these patients.

OBJECTIVES: To perform a systematic review of the literature and a meta-analysis on traumatic kidney injuries. DATA SOURCES: A literature search was performed using PubMed, Embase, and Scopus databases. Articles published in English, French and Spanish were selected from 1963 to 2018. MeSH terms utilized were renal trauma, kidney trauma, blunt renal trauma, and penetrating renal trauma. STUDY PARTICIPANTS: The eligilibility criteria included only original and human subject articles. Articles not involving human patients, cancer related, review articles, surveys, iatrogenic injuries, pediatric patients, and case reports were excluded from this search.

RESULTS: Forty-six articles met the inclusion criteria of which 48,660 patients were identified and included in this review. Gender was reported in 32,918 cases, of which 75.3% of patients were male with a mean age of 33 years. Of the 44,865 patients where the mechanism of injury was described, we identified 36,086 (80.5%) patients that sustained blunt trauma, while 8,779 (19.5%) were due to penetrating mechanisms. Twenty one series with a total of 31,689 patients included the mortality rate. Overall mortality rate with exact binomial 95% confidence interval estimated via random effects model was 6.4% (4.8%-8.4%).

CONCLUSIONS: Non-operative management has become the standard in renal trauma management with good results in morbidity and mortality. This has resulted in a decrease in the number of unnecessary iatrogenic nephrectomies and potential improvement in a patient's quality of life. When an invasive treatment is necessary, angioembolization for active bleeding or nephrorrhaphy is usually sufficient.
