Changes in urinary output during laparoscopic adrenalectomy.

Abstract

To better understand the physiological effects of pneumoperitoneum, by examining changes in urinary output during gaseous and gasless laparoscopic adrenalectomy. Laparoscopic adrenalectomy was performed with gas in six patients and without in three. Urinary output was measured during insufflation and after desufflation. In all patients who received gas, the urinary output was significantly decreased during insufflation and significantly increased after desufflation. However, there were no changes in urinary output in patients who did not receive gas. For the safety of laparoscopic surgery it is important to recognise that oliguria occurs during pneumoperitoneum, although the changes in urinary output caused no complications in renal function.
