腹腔鏡下腎部分切除術における術後腎機能に影響を与える因子の検討

Abstract

We retrospectively investigated the relationship between postoperative renal function and operative factors. We performed 99m Tc-mercaptoacetyltriglycine (MAG) 3 renography for 10 patients after they underwent laparoscopic nephron-sparing surgery for renal cell carcinoma in our institute from 2003 to 2008. We used serum creatinine level and 99mTc-MAG 3 renogram to assess the postoperative renal function, and assessed whether the findings correlated with physical and operative factors. There was no relationship between the rate of increase in creatinine level and other factors ; the % reduction determined from the preoperative and postoperative renograms showed a significant correlation with the operation time and the ischemic time. It is important to shorten the duration of operation and ischemia to preserve the renal function after laparoscopic nephron-sparing surgery.
