title: Changes in urinary output during laparoscopic adrenalectomy.
abstract: OBJECTIVE
  To better understand the physiological effects of pneumoperitoneum, by examining changes in urinary output during gaseous and gasless laparoscopic adrenalectomy.
  
  
  METHODS
  Laparoscopic adrenalectomy was performed with gas in six patients and without in three. Urinary output was measured during insufflation and after desufflation.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
