OBJECTIVE
In this video we will demonstrate endo-ureterotomy using a cutting balloon for vesico-ureteric junction (VUJ) dilatation and stenting of the primary obstructive megaureter.
METHOD
For the technique, a 0.014 inch guide-wire is endoscopically inserted through the VUJ and allowed to curl in the megaureter. A 3 mm atherotome-bladed cutting balloon is inflated with iohexol contrast solution. Under fluoroscopy or cystoscopically, the stenotic VUJ segment is observed to open and post-dilated with a 4 mm simple balloon before JJ stent placement for six weeks.
RESULTS
This video demonstrates the equipment and technique of VUJ endo-ureterotomy using a cutting balloon and stenting of the primary obstructive megaureter.
CONCLUSION
Where intervention for the primary obstructive megaureter is indicated, we propose VUJ endo-ureterotomy as the first line treatment.
目的
在本视频中，我们将演示使用切割球囊进行腔内输尿管切开术，以扩张膀胱输尿管连接部（VUJ）并对原发性梗阻性巨输尿管进行支架置入。
方法
对于该技术，通过内窥镜插入 0.014 英寸导丝，并使其在巨输尿管中卷曲。用 iohexol 对比溶液充气 3 毫米动脉切开刀片切割球囊。在透视或膀胱镜下，观察狭窄的 VUJ 段开放，并在放置 JJ 支架 6 周前用 4 毫米简单球囊进行后扩张。
结果
本视频演示了使用切割球囊进行 VUJ 腔内输尿管切开术和原发性梗阻性巨输尿管支架置入的设备和技术。
结论
对于原发性梗阻性巨输尿管，我们建议将 VUJ 腔内输尿管切开术作为一线治疗方法。
