ABSTRACT

Background: Trauma is a frequent cause of death in persons from one to 44 years of age and 10% of abdominal trauma affects the kidney.
Aims: To determine the relation between the associated abdominal injuries plus the grade and type of renal injury and the frequency of nephrectomy in patients with abdominal trauma.
Methods: A retrospective, comparative, cross-sectional study was conducted on 86 polytraumatized patients that had renal injury and required surgical management within the time frame of January 1, 2006 to December 31, 2010. The patients were divided into two groups: Group 1 included patients that underwent nephrectomy and Group 2 was made up of patients that did not undergo the procedure.
The variables analyzed were age, sex, injury mechanism (a sharp cutting instrument, bullet, or contusion), associated injuries, and renal injury grade. These variables were analyzed using the chi square test and statistical significance was considered with a p‹0.05.
Results: The factors determining nephrectomy in polytraumatized patients that had concomitant abdominal trauma were the grade of renal injury and gunshot wounds. There was no relation between the number of associated injuries and nephrectomy. Stab wounds showed a lower probability of nephrectomy.
Conclusions: The associated injuries did not increase nephrectomy frequency. However, there was an increase in nephrectomy in relation to renal injury grade and gunshot wound; there was a lower propensity for nephrectomy with respect to stab wounds.
