Ureteral replacement with a new prosthesis.
A new flexible silicone ureteral prosthesis has been developed and implanted by a new technique in 20 miniature pigs. The improved implantation technique and the results are described. All prostheses remained firmly attached in their position and drained the upper urine collecting system adequately during an observation period up to 12 mos. Leakage, incrustation, dislocation or rejection did not occur. The promising results encouraged us to continue our investigations to get long term experience for clinical trial in human patients for whom nephrostomy is the alternative.
