Objective: To evaluate the effects of different CO(2) pneumoperitoneum conditions on renal function in rats and provide experimental evidence for improving renal graft function after transplantation.
Methods: SD rats were randomized into 10 groups (n=12) and subject to CO(2) pneumoperitoneum at different pressures (0.67, 1.33 and 2.0 kPa) for 60 or 120 min. Serum urea nitrogen (BUN), creatinine (Cr) and N-acetyl-β-D-glocosaminidase (NAG) levels were detected after pneumoperitoneum.
Results: As the pressure and time of pneumoperitoneum increased, the renal function deteriorated gradually, showing significant differences between the groups (P<0.05).
Conclusion: Increased pressure and prolonged duration of CO(2) pneumoperitoneum causes impairment of the renal function, suggesting the necessity of reducing the operative time and lowering the pressure of pneumoperitoneum when harvesting renal graft in living donors.
