Abstract: ［Abstract］ Objective〖HTSS〗To evaluate the curative effect of transperitoneal 3D laparoscopy and traditional 2D laparoscopy in the treatment of children with ureteropelvic junction obstruction.
〖HTH〗〖WTHZ〗Methods〖HTSS〗A total of 84 patients with the disease of ureteropelvic junction obstruction were enrolled. All of them were operated through the peritoneal pathway. 24 cases in the 3D group received 3D laparoscopic pyeloplasty, while 27 cases in the 2D group received 2D laparoscopic pyeloplasty. The surgical results were compared between the two groups.
〖HTH〗〖WTHZ〗Results〖HTSS〗All of the surgeries were uneventful, and no serious complications were found after following up for more than 6 month. The operative time between the two groups had significant difference, which 3D group shorter than 2D group(P＜0.05)，but no obvious difference happened in the intraoperative blood loss and postoperative hospital stay(P＞0.05).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗3D laparoscope can display threedimensional vision during surgery like the real vision, which can make the field of surgery lifelike, reduce the degree of surgery, shorten the operative time, and improve the accuracy and safety of laparoscopic surgery. 3D laparoscope can make a certainly curative effect and significantly clinical value.
