Laparoscopic pyelolithotomy in patients with previous ipsilateral renal stone surgery.

To evaluate the safety and efficacy of transperitoneal laparoscopic pyelolithotomy in renal stone cases with previous renal surgeries. In this prospective study, 190 consecutive patients with renal stones, who were candidates for transperitoneal laparoscopic pyelolithotomy, were enrolled. The patients were divided into two groups. In group A, 163 patients without a history of renal surgery underwent standard laparoscopic pyelolithotomy, whereas in group B laparoscopic pyelolithotomy was performed in 27 patients with a history of kidney stone surgery including percutaneous nephrolithotomy or open stone surgery. All intraoperative data including the operating time and complications such as bleeding requiring transfusion were recorded. Postoperative data such as length of hospitalization, hemoglobin level alteration, and other complications were also recorded. There was no significant difference in the preoperative data such as stone size, stone site, age, sex, and stone side between the two groups. There was no significant difference in the stone-free rate between the two groups (p = 0.4). There was no significant difference between the two study groups regarding the operating time, hospital stay, stone-free rate, complications, and transfusion rate. Laparoscopic pyelolithotomy can be used as a safe and feasible treatment modality in the setting of previous renal surgery. The complications and stone-free rate of laparoscopic pyelolithotomy in patients with history of renal surgery are acceptable.
