Abstract
BACKGROUND: Minimally invasive procedures have become the standard option for treatment of urinary stones; the use of more invasive techniques is not a common practice currently. This emergent technology is not always available and laparoscopy is the alternative option. There are few reports of laparoscopic management for urinary lithiasis in pediatric patients. This study is about the use of laparoscopic surgery combined with pyeloscopy as a feasible first-line treatment for pediatric urolithiasis in renal and proximal ureteral locations. PATIENTS AND METHODS: We reviewed the records of 14 patients with renal and proximal ureteral stones who underwent laparoscopic pyelolithotomy and pyeloscopy in a period from January 2011 to July 2016. The outcome measures were needed for auxiliary procedures, treatment success, and complication rates. RESULTS: A total of 16 procedures were carried out in 14 patients, 15 transperitoneal and 1 retroperitoneal laparoscopic pyelolithotomies were done. It was necessary to perform upper ureterolithotomies to remove ureteral stones in 2 cases. The holmium laser and/or pneumatic lithotripter were used to fragment staghorn calculi. Some of the complications were blood transfusion in 12.5% and self-limited urinary leak in 18.7% of the patients. The success rate after undergoing one procedure was 92.8%. CONCLUSIONS: Transperitoneal or retroperitoneal laparoscopic lithotomy is a safe and feasible procedure for the treatment of pediatric urolithiasis. It can be an alternative to shock-wave lithotripsy and percutaneous nephrolithotomy when these are not feasible or possible.
