[Postoperative acute kidney failure: comparative study in abdominal surgery].
Five hundred and eighty-two patients were examined in a retrospective study to identify the incidence of postoperative acute renal failure (ARF) in obstructive jaundice. The patients were treated at the "Hospital das Clínicas da UFMG" during a 10 year period (1977-1987), and were operated on for gastric carcinoma, portal hypertension, peritonitis, and obstructive jaundice. The incidence of ARF was 4.9% (29 patients), and increased in patients with peritonitis and obstructive jaundice (p less than 0.0001) and decreased in the patients with gastric carcinoma. Infection was significant when associated to ARF in patients with portal hypertension and peritonitis, but not significant in patients with gastric carcinoma and obstructive jaundice (p less than 0.001). These results show the importance of postoperative ARF in obstructive jaundice.
