Duval and Tesson,4 1900: Three dogs; bilateral ureterointestinal anastomosis; two dogs died of pyelonephritis. These experimenters operated on three dogs, in each case implanting both ureters in the rectum. They combined the operative technique of Kryñski and Fowler. The ureters were secured obliquely on a mucosal flap; over this flap were sutured the serosal and muscular layers.
One dog died twenty hours after the operation, from defective technique. Both ureters were found obliterated. One dog lived two and one-half months. Post-mortem showed the uretero-rectal anastomosis good; ureters patent. Bilateral pyelonephritis existed without distention. The third dog lived seven months. An autopsy showed the uretero-rectal orifices patent with slightly dilated ureters. Both kidneys were markedly distended and were the seat of grave pyelonephritic lesions. The mucous valves were atrophied so as to be unserviceable. The conclusions were that uretero-intestinal anastomosis could only be successful when the trigonum, together with the
