Of these 47 children, 27 received RSPY while 20 underwent LSPY. The baseline data, operation time, intraoperative anastomosis time, intraoperative blood loss, postoperative hospital stay, complications, total cost, preoperative and postoperative renal parenchymal thickness (PT), anteroposterior renal pelvis diameter (APD), and differential renal function (DRF) of the two groups were compared to evaluate the clinical efficacy of the two surgical methods.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results showed that both surgical techniques were successful and no patient transitioned to open surgery. There was no significant difference between the two groups in baseline data, intraoperative blood loss, complications, APD, and PT 6 months after surgery. There was also no significant difference in APD, PT, and DRF 12 months after surgery (all <jats:italic>P<\/jats:italic>\u2009&amp;gt;\u20090.05). Compared with the LSPY group, the RSPY group had shorter operation time [(153.04\u2009\u00b1\u200914.44) vs. (189.90\u2009\u00b1\u200932.59) min, <jats:italic>t<\/jats:italic>\u2009=\u2009\u22125.24, <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.05], less intraoperative anastomosis time [(68.81\u2009\u00b1\u200916.80) vs. (97.45\u2009\u00b1\u200911.99) min, <jats:italic>t<\/jats:italic>\u2009=\u2009\u22126.49, <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.05], shorter postoperative hospital stay [(5.96\u2009\u00b1\u20091.34) vs. (9.00\u2009\u00b1\u20091.33) d, <jats:italic>t<\/jats:italic>\u2009=\u2009\u22127.68, <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.05], but higher total cost [(57,390\u2009\u00b1\u20097,664) vs. (30,183\u2009\u00b1\u20094,219) yuan, <jats:italic>t<\/jats:italic>\u2009=\u200914.32, <jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.05].<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Compared with LSPY, RSPY achieves equivalent efficacy in the treatment of UPJO in children and has certain advantages by shortening the operation time, intraoperative anastomosis time, and postoperative hospital stay.
