Percutaneous stenting of the severely strictured ureter is facilitated by catheterization through a rigid curved tube leading through the kidney. Alternatively, bidirectional traction tensioning of a guide wire pulled through the entire urinary tract permits antegrade dilatation and stent drainage. Complete occlusion near the ureteric orifice may be bypassed by transureteral puncture of the bladder followed by stent insertion.
通过经肾脏的刚性弯曲导管进行插管有助于对严重狭窄的输尿管进行经皮支架置入。或者，对穿过整个尿路的导丝进行双向牵引张紧可实现顺行扩张和支架引流。输尿管口附近的完全闭塞可通过经膀胱穿刺输尿管并随后置入支架来绕过。
