Abstract:

Objective     To study therapeutic effects of abdominal laparoscopic pyeloureterolithotomy and open surgery on treating renal pyelic calculi and upper segment ureteral calculi, and evaluate the value of laparoscopy. Methods     84 patients were included in this study and all underwent pyeloureterolithotomy, 28 by abdominal laparoscopy(group A) and 56 by open surgery(group B). The data of basics(age， sex， height， weight and medical history), stone characteristics (size and location), operation(operating time and bleeding volume), complication rate, postoperation(recovery of intestinal function and ambulation after operation), cost of hospitalization and hospital stay time were retrospectively analyzed. Results     All surgeries in groups A and B were successful. The basics, stone characteristics and complication rate showed no significant difference. Group A had less average bleeding volume in operation, quicker recovery of intestinal function and ambulation after operation, and shorter hospital stay than group B(P＜0.05).While group B had shorter operating time and less cost of hospitalization(P＜0.05). Conclusion     Laparoscopic pyeloureterolithotomy has the characteristics of mini-invasion, little bleeding and quick recovery. It has the same indications as open surgery, and may replace open surgery under given conditions.
