A transverse skin incision of 12 mm in length was created approximately 1 cm above the iliac crest. Muscle was spared and retracted with stay sutures to expose the retroperitoneal space. Subsequently, a balloon trocar was then inserted, and pneumoperitoneum was achieved. A 10 mm operating laparoscope (Stema, Germany) with a Maryland was used to dissect and isolate the ureters from surrounding tissues. The ureters were then exteriorized and end-to-side ureteroureterostomy was performed using Polydioxanone (PDS) 6\/0 running sutures. Patient\u2019s demographic, operative, and follow-up data were collected prospectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The mean age of patients was 25.2 months (range: 1\u2013105 months). The mean operating time was 81.9 \u00b1 11.3 minutes. There were no intraoperative conversions or complications. After a median follow-up time of 47.5 months, the differential renal function of the pathological upper pole moiety (UPM) was preserved in all patients. Ultrasound revealed a significant reduction in UPM\u2019s renal pelvis anterior\u2013posterior diameter from 19.6 \u00b1 9.1 mm preoperatively to 11.1 \u00b1 6.7 mm postoperatively (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.05), accompanied by a reduction in ureter\u2019s diameter from 10.8 \u00b1 4.4 mm to 4.8 \u00b1 1.2 mm (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.05).
