To describe a simple, novel method to achieve ureteric access in the Cohen crossed reimplanted ureter, which will allow retrograde working access via the conventional transurethral method.
Under cystoscopic vision, suprapubic needle puncture was performed. The needle was directed (bevel facing) towards the desired ureteric orifice (UO). A guidewire (with a floppy-tip) was then inserted into the suprapubic needle passing into the bladder, and then easily passed into the crossed-reimplanted UO. The distal end of the guidewire was then removed through the urethra with cystoscopic grasping forceps. The straightened ureter then easily facilitated ureteroscopy access, retrograde pyelogram studies, and JJ stent insertion in a conventional transurethral method.
The UO and ureter were aligned in a more conventional orthotopic course, to allow for conventional transurethral working access.
A novel method to access the Cohen crossed reimplanted ureter was described. All previously published methods of accessing the crossed ureter were critically appraised.
描述一种简单、新颖的方法，用于在科恩交叉再植输尿管中实现输尿管通路，该方法将允许通过传统经尿道方法进行逆行操作通路。
在膀胱镜直视下，进行耻骨上针刺。将针（斜面朝向）指向所需的输尿管口（UO）。然后将一根导丝（尖端柔软）插入耻骨上针并进入膀胱，然后轻松进入交叉再植的输尿管口。然后用膀胱镜抓钳通过尿道取出导丝远端。伸直的输尿管随后便于以传统经尿道方法进行输尿管镜检查、逆行肾盂造影研究和置入双J支架。
输尿管口和输尿管排列成更传统的原位路径，以允许进行传统经尿道操作通路。
描述了一种进入科恩交叉再植输尿管的新方法。对以前发表的所有进入交叉输尿管的方法进行了严格评估。
