Hepatectomy in patients with nonuremic minimal renal failure

In this study, the perioperative management and short-term outcome of hepatectomy were evaluated in patients with nonuremic minimal renal failure to assess the safety of hepatectomy in such patients. Ninety-one patients who underwent hepatectomy were retrospectively divided into two groups based on their creatinine clearance (Ccr) values: a group with Ccr values ⩾50 but <100 ml/min (group 1; n=77) and a group with Ccr values of ⩾20 to <50 ml/min (group 2; n=14). Preoperative patient characteristics, intraoperative parameters (including operation time and blood loss), and postoperative management and complications were evaluated. The preoperative evaluation showed no differences in liver function between the two groups, and there were no statistically significant differences between the two groups in intraoperative blood loss (522 ml in group 1 and 806 ml in group 2) or intraoperative urine volume (1.01 ml/kg per hour in group 1 and 0.75 ml/kg per hour in group 2). The difference between the two groups in postoperative complications was not statistically significant. None of the patients in group 2 required dialysis therapy, and no patients died as a result of hepatectomy or hepatectomy-related causes. Adequate indications, appropriate operative procedures, and perioperative management can enable hepatectomy to be performed safely in patients with nonuremic minimal renal failure.
