Laser lithotripsy was achieved using the holmium:YAG (Ho:YAG) laser (120 W) with a 200-\u03bcm laser fiber. A Double-J stent was placed in all patients at the end of the procedure. Patient demographics, stone characteristics, operative outcomes, and complications were evaluated. The SFR was determined at 1 month postoperatively with a kidney, ureter, and bladder radiograph (KUB) and ultrasound KUB.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Sixty-eight patients were included in the study:\n                      <jats:italic toggle=\"yes\">in situ<\/jats:italic>\n                      group (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      \u2009=\u200935) and relocation group (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      \u2009=\u200933).
