Abstract

OBJECTIVES: We report our experience with retroperitoneoscopic pyelolithotomy for renal pelvis stone disease (>1.5 cm) and comparisons were made with reference to type of renal pelvis, intrarenal or extrarenal. MATERIAL AND METHODS: Sixty patients underwent retro- peritoneoscopic pyelolithotomy for large renal pelvis stone disease (>1.5 cm) in our hospital between 2008 and 2012.The patients in both the groups (Intrarenal or Extrarenal) were assessed preoperatively and intra operatively. Variables such as operative time, need for DJ stent placement either pre op/intra op / post op, drain placement, drain removal, post op mean hospital stay were compared between the two groups. We excluded patients with history of renal surgery. RESULTS: Conversion was required in five cases (8.3%). None of the patients landed in significant medical post op complications. In total DJ stent was inserted in 26 patients (43.3%), pre operatively, in eight patients and intra-operatively, in 18 patients. No patient required post op D J stent placement Average duration of surgery was 133.4 mins. Mean postoperative hospital stay was 4.44 days. (Ranged from 3-8 days). CONCLUSION: Retroperitoneoscopic Pyelolithotomy is the preferred treatment modality in patients in which open surgery is contemplated. We conclude that it is better to place DJ stent either pre op or intra op since it facilitates suturing of pelvis. Drain removal was done slightly earlier in patients with intrarenal pelvis group. There was no significant difference in post-operative mean hospital stay among both the group. Conversion rate was more with intrarenal pelvis.
