Laparoscopic cholecystectomy (LAP) may temporarily reduce kidney function, including urine output, renal plasma flow, and glomerular filtration rate. Minilaparotomy cholecystectomy (MINI) showed no significant impact on these parameters during surgery.

Area of Science:

  • Surgical Innovation
  • Nephrology
  • Anesthesiology

Background:

  • Laparoscopic cholecystectomy (LAP) is a minimally invasive surgical technique.
  • Understanding the impact of intra-abdominal pressure during LAP on renal function is crucial.

Purpose of the Study:

  • To compare the effects of laparoscopic cholecystectomy (LAP) versus minilaparotomy cholecystectomy (MINI) on renal function.
  • To assess intraoperative changes in hemodynamic parameters and renal function tests.

Main Methods:

  • Prospective study comparing 7 patients undergoing LAP (12 mm Hg intra-abdominal pressure) with 7 patients undergoing MINI.
  • Serial monitoring of systemic hemodynamic parameters and renal function tests (urine output, effective renal plasma flow, glomerular filtration rate).

Main Results:

  • No significant hemodynamic or renal function changes were observed in the MINI group.
  • In the LAP group, a significant decrease in urine output, effective renal plasma flow, and glomerular filtration rate was noted 60 minutes after pneumoperitoneum initiation.

Conclusions:

  • Pneumoperitoneum during laparoscopic cholecystectomy may transiently impair renal function.
  • Minilaparotomy cholecystectomy appears to have a less pronounced effect on intraoperative renal function compared to LAP.
