ABSTRACT-This study was carried out to evaluate two different Laparoscopic Ureterolithotomies, Laparoscopic Transperitoneal ureterolithotomy (TPUL) and Retroperitoneal ureterolithotomy (RPUL). This study was conducted on 45 [25 cases for TPUL and 20 cases for RPUL] selected patients of single large impacted calculus of size more than 8mm in upper and middle ureter. It was observed that conversion to open ureterolithotomy was observed in 4 cases and excessive bleeding in one case for Transperitoneal ureterolithotomy. On the other hand excessive bleeding was present in one patient while need for conversion to open ureterolithotomy was seen in 8 cases in case of Retroperitoneal ureterolithotomy. No major perioperative complications were seen in either study. Both the procedures have definitely shown decreased post-operative discomfort, decreased requirement of post-operative analgesia, better cosmesis, early return to work, and less morbidity with acceptable variations in these parameters between two studies.
