Oliguria during laparoscopic surgery.
Oliguria is infrequently viewed as a complication of laparoscopic surgery. The rate of urine output in six healthy patients undergoing laparoscopic surgery was measured during the period of CO2 pneumoperitoneum and for several hours after desufflation. The average hourly urine output during insufflation was 0.30 +/- 0.14 mL/kg despite an average hourly intravenous infusion rate of lactated Ringer's solution of 13.0 +/- 4.0 mL/kg. After release of pneumoperitoneum, urine output increased 467% to 1.7 +/- 1.1 mL/kg per hour. Patients remained hemodynamically unchanged perioperatively. Preoperative and postoperative blood urea nitrogen and creatinine concentrations did not significantly differ. We discuss the potential etiologic factors in the development of oliguria in the setting of the increased intra-abdominal pressure of pneumoperitoneum and the implications of this acute but reversible renal dysfunction.
