Ureterorenoscopic Lithotripsy for Pediatric Kidney Stones Using Holmium:Yttrium-Aluminum-Garnet Laser Devices: 15 W 30 W.

We aimed to compare the effectiveness of 15- and 30-W holmium:yttrium-aluminum-garnet (Ho:YAG) laser devices used in the treatment of pediatric kidney stones. Eighty-six consecutive pediatric patients who underwent retrograde intrarenal surgery (RIRS) between February 2010 and August 2020 were enrolled in the study. After exclusion criteria were applied, the data of 79 children were evaluated retrospectively.
