[An analysis of transfusion in surgery on the bladder]

To analyze the perioperative transfusion incidence in the operated patients of the urinary bladder.

We reviewed the records of all patients operated in 1996. The abstracted patient discharge records were codified according to the ICD-9-CM codes. Gender, age, codes of diagnosis, of procedures, among them blood transfusions, and of surgical procedures.

There were studied 120 patients of which 12 (10%) were transfused. By univariate analysis, it has been detected an association, significative statistically, of the transfusion with: 1) the principal diagnosis (p: 0.017); where alone the patients with bladder cancer were transfused; 2) diagnosis of perioperative anemia (p: 0.026); 3) the age, with a direct relation among age and transfusion rate (p: 0.001); 4) and with the number of codified diagnoses, indirect indicator of the comorbidity p: 0.003).

In our data, among the variables studies, the transfusion is associated with the principal diagnosis, diagnosis of anemia, number of codified diagnoses and the age.
