Objective To compare the treatment effects of abdominal and retroperitoneal laparoscopic ureterolithotomy in upper ureteral calculi. Methods A total of 56 cases of upper ureteral stones was received laparoscopic ureterolithotomy,including 24 cases of abdominal laparoscopic approach and 32 cases of retroperitoneal access. Results Two operations were converted to open surgery because dense adhesion around right upper ureter calculus made dissection difficult (1 in laparoscopic approach group);stones slipping into the pelvis(1 in retroperitoneal group). The operative time and blood loss were no significant difference between two groups. The length of hospital stays and hospital costs were different significantly between two groups. There were no postoperative calculus remained and no postoperative complications occurred at postoperative follow-up. Conclusion Both abdominal and retroperitoneal laparoscopic uretertolithotomy are effective and safe minimally invasive procedures. Retroperitoneal approach has an advantage in saving hospital cost and shortening hospital stays.
