Preoperative assessments included imaging studies (kidney, ureter, and bladder X-ray; noncontrast computed tomography; and renal ultrasound) and laboratory tests (complete blood count, biochemical tests, coagulation function, and urine culture). The stone clearance rate, operation time, intraoperative blood loss, and complications were compared between the two groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Baseline characteristics of the two groups were balanced.
