There are 2 critical steps of stent placement during laparoscopic pyeloplasty (LP) in children. Introduction to the ureteropelvic junction and passing through the ureterovesical junction. We aimed at overcoming those 2 steps by creating a modified technique.
Consecutive 27 children undergoing transperitoneal laparoscopic dismembered pyeloplasty by a single surgeon were prospectively enrolled into this study. The modifications of our technique are using an Amplatz dilator and a closed tip stent.
The mean age of the children was 6.7 (range 4 months-17 years). The mean time of stent insertion was 2.7 ± 2.0 (2-6) min and the operative time was 128.3 ± 17.6 (90-180) min. The mean number of days of hospital stay was 2.0 ± 0.4 (1-3). After a mean follow-up period of 20.3 ± 4.2 (14-30) months, no operative failure was detected.
Our modified technique is a completion of the current armamentarium for stent placement during LP in infants and children.
儿童腹腔镜肾盂成形术（LP）中支架置入有两个关键步骤。将支架引入肾盂输尿管连接部并使其通过输尿管膀胱连接部。我们旨在通过创建一种改良技术来克服这两个步骤。
连续27例接受经腹腹腔镜离断性肾盂成形术的儿童由同一外科医生前瞻性纳入本研究。我们技术的改良之处在于使用了安普拉斯扩张器和封闭头支架。
儿童的平均年龄为6.7岁（范围4个月至17岁）。支架置入的平均时间为2.7±2.0（2 - 6）分钟，手术时间为128.3±17.6（90 - 180）分钟。平均住院天数为2.0±0.4（1 - 3）天。平均随访20.3±4.2（14 - 30）个月后，未发现手术失败情况。
我们的改良技术完善了目前婴幼儿和儿童LP术中支架置入的器械库。
