title: [Analysis of transfusion in kidney surgery].
abstract: OBJECTIVE
  To analyze the likelihood of perioperative transfusion in patients undergoing renal surgery.
  
  
  METHODS
  The records of all patients who had undergone renal surgery in 1996 were reviewed. The abstracted patient discharge records, encoded according to the ICD-9-CM, were analyzed for gender, age, diagnosis, surgical and non-surgical procedures including transfusions of blood products.
  
  
  RESULTS
  21 (23.3%) of 90 patients who had undergone renal surgery required transfusion. By univariate analysis, the incidence of transfusion was statistically significantly higher in patients with chronic nephropathy, patients undergoing total nephrectomy and renal transplantation, and those having a greater number of ICD-9-CM diagnosis codes (indirect indicator of the clinical severity and comorbidity). By multivariate logistic regression analysis, the surgical procedure was found to be the only predictive factor for blood transfusion (p = 0.013). The main diagnosis, number of diagnosis codes, gender, number of surgical techniques and age were not found to be predictors of transfusion.
  
  
  CONCLUSIONS
  Our data show that of the variables analyzed, the surgical procedure is the only predictive factor of the likelihood of requiring blood transfusion.
