Abstract: Objective To analyses the clinical experience of laparoscopic nephron sparing surgery for treatment of complex renal cyst. Methods 19 cases of complex renal cyst treated with laparoscopic partial nephrectomy were analyzed retrospectively. There were 7 males and 12 females, with the mean age of 43.3 years (28 to 59 years). The locations were 9 cases in the middle of the kidney, 4 cases in the upper pole and 6 cases in the lower pole of the kidney. The mean diameter of the renal cyst mean was 3.32cm (2.5 to 5.1cm). There were 6 cases of type II, 7 cases of type IIF, 4 cases of type III and 2 cases of type IV according to the Bosniak classification. Results 19 patients were performed laparoscopic nephron sparing surgery successfully. The mean operation time was (76±22.4) min (60 to 130 min), and the mean intraoperative blood loss was 38ml (20 to 100 ml). The mean renal artery occlusion time was 17.0min (14 to 28min), and there was no significant change in serum creatinine before and after operation. The pathological results were 18 cases of renal clear cell carcinoma and 1 case of simple renal cyst, with negative margins. Conclusions Laparoscopic nephron sparing surgery can resect the possible malignant renal cyst completely no matter it is benign or malignant, and can preserve the kidney while avoiding some medical risks.
