Abstract

PURPOSE: To estimate the incidence and risk of significant renal injury quantitatively in the admitted patients with abdominal trauma.
MATERIALS AND METHODS
From January 1992 to July 1997, 511 patients who admitted to departments of urology and general surgery due to major abdominal trauma with and without renal injury were included in this study. The risk of renal injury was defined as the percentage of square of Abbreviated Injury Scale of kidney in the Injury Severity Score(ISS) per each patient. The patients were classified to 5 groups according to the causes of trauma as traffic accident, falls, assault, other blunt and stab Injury, then compared the incidence and risk of renal injury each other.
RESULTS
The overall incidence of significant renal injury was 14.9%, and the incidence according to the causes was 27.0%,20.8%, 16.1%, 14.3% and 10.7% in falls, assault, stab injury, other blunt and traffic accident, respectively. The overall risk of significant renal injury estimated by ISS was 15.7% and the risk according to the causes was 26.7%,24.9%, 11.9%,9.9% and 4.9% in assault, falls, traffic accident, other blunt and stab injury, respectively Mean ISS in the patients with renal injury was markedly higher than that of the patients without renal injury(27.5 vs 13.6)(p < 0.01).
CONCLUSIONS
Our study shows that both the incidence and risk of significant renal injury in the admitted patients with abdominal trauma can be expected in the probability of 15% or so, and according to the causes, those in the traumatized patients by the assault and falls mark high.
