The authors report a retrospective series of 65 cases of renal contusion in children affecting 45 boys and 20 girls between the ages of 10 months and 15 years (mean age: 10 years). The causes of renal trauma were dominated by household accidents (53.8%) and road accidents (33.8%). Associated extrarenal lesions were observed in 21.5% of cases. 55.4% of the 65 contusions were considered to be benign, 27.7% of moderate severity and 16.9% were serious. The blunt trauma affected a pathological kidney in 19 cases. Exclusively medical treatment was recommended in 31 patients, while surgery was indicated in the other 34 patients. Apart from one death in a context of multiple trauma, few complications were observed in the group of operated patients and consisted of 4 cases of urinary fistula and 4 cases of infection, all of which resolved.
