Laparoscopic Surgery for Renal Stones: Is it Indicated in the Modern Endourology Era?

Purpose: To report the outcomes of laparoscopic surgery combined with endourological assistance for the treatment of renal stones in patients with associated anomalies of the urinary tract. To discuss the role of laparoscopy in kidney stone disease. Materials and Methods: Thirteen patients with renal stones and concomitant urinary anomalies underwent laparoscopic stone surgery combined with ancillary endourological assistance as needed. Their data were analyzed retrospectively including stone burden, associated malformations, perioperative complications and outcomes. Results: Encountered anomalies included ureteropelvic junction obstruction, horseshoe kidney, ectopic pelvic kidney, fussed-crossed ectopic kidney, and double collecting system. Treatment included laparoscopic pyeloplasty, pyelolithotomy, DQGQHSKUROLWKRWRP\FRPELQHGZLWKÀH[LEOHQHSKURVFRS\DQGVWRQHUHWULHYDO,QWUDRSHUDWLYHFRPSOLFDWLRQVZHUHORVWVWRQHV in the abdomen diagnosed in two patients during follow up. Mean number of stones removed was 12 (range 3 to 214). Stone free status was 77 % (10/13) and 100 % after one ancillary treatment in the remaining patients. One patient had a postoperative urinary leak managed conservatively. Laparoscopic pyeloplasty was successful in all patients according to clinical and dynamic renal scan parameters
