The technique of ureterocystoneostomy in experimental renal orthotopic allotransplantation in the pig.
Experimental orthotopic renal allotransplantation performed in pigs allowed us to verify some techniques of ureterocystoneostomies from the urological point of view. For the reconstruction of the urinary pathways we employed anastomosis in 7 cases, and implantation of the ureter into the bladder in 3 cases, using the antireflux technique in 9 animals and the now common ureteral implantation with the terminal segment of the ureter placed in tunnel serosa in 24 animals. The results of our modification confirm the importance of peritoneal plasty of the terminal ureteral segment for the prevention of urinary fistulas. This technique seems to be applicable to reconstruction of urinary pathways in humans.
