An oblique end‐to‐side anastomosis of one ureter to the contralateral ureter (transureteroureterostomy) may permit salvage of a kidney whose middle or distal ureter is not salvageable by standard repair techniques. This procedure was done with intraoperative magnification and microsurgical techniques in 5 experimental dogs. Animals were euthanized for healing studies at 1, 3 and 5 weeks, and the results correlated with postoperative and preterminal excretory urograms. Healing of the anastomosis was organized by layers and completed both grossly and histologically in all animals at 5 weeks. Ureter function was retained except for short‐term, mild, postoperative hydroureter. Potential clinical indications for transureteroureterostomy are: 1) middle or distal ureteral transection due to trauma; 2) delayed recognition of iatrogenic intraoperative severence or ligation; 3) distal ureteral neoplasia; and 4) selected cases of ectopic ureter. Complications include dehiscence, stricture, or the dissemination of infection or neoplasia which would compromise proximal ureters and both kidneys.
