RESUMO
Fifteen patients with chronic renal failure(CRF)underwent laparoscopic cholecystectomy(LC)at carbon dioxide(CO2)pneumoperitoneum pressure of 10-12 mm Hg(Group A,n=9)or 13-15 mm Hg(Group B,n=6).Renal function and urinary volume(UV)of Group A showed no remarkable change following the operation.But in Group B,the levels of blood urine nitrogen(BUN)and serum creatine(Scr)were increased significantly,and creatinine clearance rate(Ccr)and UV were remarkably decreased(P＜0.05).These variants gradually retumed tO the preoperative levels after 1 week.The analysis showed that laparoscopic choleeystectomy at CO2 pneumoperitoneum pressure of 10-12 mm Hg in CRF patients might be safe.Higher CO2 pneumoperitoneum pressure could result in reversible renal Email:yuanhuizhong2000@yahoo.com.cnfunction change.
