Since 2/02 to 2/03 a total of 13 patients underwent either pyelovesical bypass (10 patients) or pyelocutaneous bypass (3 patients). A composite implant, consisting of two coaxial tubes internal pure smooth silicone covered by coiled e-PTFE has been designed to serve as the ureteral replacement. This prothesis in inserted percutaneously into the renal pelvis, tunnelled subcutaneously, and introduced through a small suprapubic incision in the bladder or out directly through a cutaneous orifice.
One encrustation of the subcutaneous pyelocutaneous bypass was observed, no angulation or dislocation during a mean follow up of 6.2 month. Improvement in the quality of life was stressed in all patients.
The subcutaneous urinary division using a silicone-PTFE prothesis is an efficient and minimal-invasive technique to attend malignant obstructions of the ureter.
从2002年2月至2003年2月，共有13例患者接受了肾盂膀胱分流术（10例）或肾盂皮肤造瘘术（3例）。设计了一种复合植入物，由两根同轴管组成，内部为纯光滑硅胶，外部覆盖有卷曲的e-PTFE，用作输尿管替代物。该假体经皮插入肾盂，经皮下隧道，通过膀胱上的一个小耻骨上切口引出或直接通过皮肤造口引出。
观察到1例皮下肾盂皮肤造瘘术出现结痂，平均随访6.2个月期间未出现成角或脱位。所有患者的生活质量均有改善。
使用硅胶-PTFE假体进行皮下尿路分流是治疗输尿管恶性梗阻的一种有效且微创的技术。
