The currently used techniques for nephrostomy sometimes fail to advance the drainage catheter through the nephrostomy track into the renal pelvis. To solve this problem a new technique has been developed. The improvement with this technique is the dilatation of the track with polypropylene dilators and a split-away sheath. The split-away sheath is threaded on the largest dilator. When the dilator is removed the drainage catheter is coaxially passed through the split-away sheath into the renal pelvis. The sheath is then removed. The technique has been used successfully in 32 patients without complications.
目前用于肾造瘘术的技术有时无法将引流导管通过肾造瘘通道推进到肾盂。为解决这一问题，已开发出一种新技术。该技术的改进之处在于使用聚丙烯扩张器和可分离鞘对通道进行扩张。可分离鞘套在最大的扩张器上。当扩张器取出后，引流导管同轴穿过可分离鞘进入肾盂。然后将鞘移除。该技术已成功应用于32例患者，无并发症发生。
