Objective To evaluate factors such as renal injury grade (Sargent Method), blunt or penetrative renal injury, injury severity score(ISS), and shock influencing the need for operation or nephrectomy, and predictive of mortality in renal injury.
Methods A well~tesigned questionnaire was used to collect medical records retrospectively. Two hundred and twenty-one cases of renal injury in West China Hospital from 1998 to 2002 were included, logistic regression analysis was used for multi-factors analysis.
Results The average age of the 221 cases was 31.6, with 191 males (86.4%) and 30 females (13.6% ), 175 blunt injuries (79.2%) and 46 penetrative injuries (20.8%), and 101 concomitant injuries (45.7%). Six cases died of renal injury (2.7%). The results of logistic regression showed that the need of operation was related to injury grade, Type of renal injury, and shock significantly. ORs (odd ratios) were 5. 965 with 95% CI 2. 767 to 12. 859, 4. 667 with 95% CI 1. 725 to 12. 628, and 2. 547 with 95% CI 1. 684 to 3. 936 respectively. The need of nephrectomy was significantly related to injury grade with OR 11. 550 and 95% CI 4. 253 to 31. 366. The death was significantly related to ISS with OR 1. 263 and 95% CI 1. 082 to 1. 411.
Conclusions The results of our data suggest the need of operation depends on injury grade, blunt or penetrative renal injury, and shock. The need of nephrectomy depends on injury grade. The death is related to ISS.
