[Reno-ureteral prosthetic by-pass operations : experimental results (author's transl)].
Results of experiments conducted in dogs are reported, in which the first few centimetres of the ureter were replaced by a prosthesis in silicone elastomer, the upper extremity being intubated by a trans-renal approach into the lower calyx and the upper extremity into the iliolumbar ureter. The one case of failure among the 6 dogs studied was due to a pyonephrosis from a technical error. In the 5 surviving dogs, the by-pass has remained permeable and there is no sign of incrustation. Control I.V.U. examinations after periods ranging from 26 months to 3 years showed normal function. This procedure has now been used in two human cases with good results.
