Abstract
MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: The subcutaneous urinary division using a silicone-PTFE prothesis is an efficient and minimal-invasive technique to attend malignant obstructions of the ureter.
