An outstanding surgical advance of recent years has been the development of a method of implanting the ureters into the bowel which reduces to a minimum the danger of ascending renal infection. The present technic depends for its success on valve action secured by having the ureter run for a distance between the muscularis and the mucosa before penetrating the lumen of the bowel.
Coffey1 conceived the application of the valve principle to transplantation of the bile duct and ureters into the bowel. He also proved its value by animal experimentation. A large number of successful transplantations of the ureters by C. H. Mayo, Coffey and others are now on record. The chapter concerning ultimate results remains yet to be written. On this account the subjoined report of the first human case in which the modern method was used is of considerable interest.
