An antireflux ureterocolonic urinary conduit was developed and evaluated in sheep. It combined the principles of the Wallace conjoined ureterointestinal conduit with the Lich extravesical ureteroneocystostomy. The procedure accomplished the following with a single anastomotic technique: joined both ureters to the intestinal stump; provided constant ureteral orifice position in the antimesenteric butt of the intestinal segment; eliminated the blind intestinal stump; prevented intestinoureteral reflux; and allowed an average of 12 times the normal urinary flow rate before exceeding mean human midureteral peristaltic pressure. The projected long term animal experiments and the sound urologic surgery principles involved indicate that the procedure may soon have clinical application.
