Ileal substitute of ureter with reflux-plasty by terminal intussusception of bowel: animal experiments and clinical experience.
The conflicting results reported after substitution of the ureter by isolated bowel segments suggest that the procedure is still hazardous. This induced us to check experimentally the performance of the ileal ureter with antireflux-plasty before using it clinically. The antireflux mechanism is constructed by intussuscepting the terminal 8 cm. of an isolated ileal segment into each other thus forming a nipple. After vesicoileostomy the nipple protrudes into the urinary bladder. In the pig vesicoileorenal reflux was prevented, and anterograde urinary flow from the kidney through the ileal ureter into the bladder was unobstructed. Finally, the case of a patient is recorded who was submitted to the same procedure successfully.
