INTRODUCTION: Our aim was to demonstrate the effect of insicion of @entity8 during open @entity1290 surgery (ORSS) on percutaneous nephrolithotomy (PNL) outcomes. METHODS: @entity1 with history of ORSS who underwent PNL operation between June 2005 and June 2015 were analyzed retrospectively. @entity1 were divided into two groups according to their type of previous ORSS. @entity1 who had a history of ORSS with parenchymal insicion, such as @entity4542 , anatrophic nephrolithotomy, lower pole resection, and partial nephrectomy, were included in Group 1. Other @entity1 with a history of open pyelolithotomy were enrolled in Group 2. Preoperative characteristics, perioperative data, stone-free status, and complications were compared between the groups. Stone-free status was defined as complete clearance of stone(s) or presence of residual fragments smaller than 4 mm. The retrospective nature of our study, different experience level of surgeons, and lack of the evaluation of anesthetic agents and cost of procedures were limitations of our study. RESULTS: 123 and 111 @entity1 were enrolled in Groups 1 and 2, respectively. Preoperative characteristics were similar between groups. In Group 1, the mean operative time was statistically longer than in Group 2 (p=0.013). Stone-free status was significantly higher in Group 2 than in Group 1 (p=0.027). Complication rates were similar between groups. @entity548 requiring blood transfusion was the most common complication in both groups (10.5% vs. 9.9%). CONCLUSIONS: Our study demonstrated that a history of previous ORSS with parenchymal insicion significantly reduces the success rates of PNL procedure.

The effects of previous open XXXX surgery types on PNL outcomes.
