title: Ileal segment replacement of ureter. I. Effects on kidney of refluxing vs nonrefluxing ileovesical anastomosis.
abstract: Unilateral partial ureteral obstruction was induced in 32 dogs followed by total ileal replacement of the obstructed ureter. The morphologic and functional effects on the kidney using a freely refluxing versus a nonrefluxing ileovesical anastomosis were compared, as well as the effect of total tapering of the reimplanted ileal segment. The tapered ileovesical anastomosis proved more reliable for prevention of reflux than the nontapered technique. Reflux prevention does not appear necessary for maintaining renal morphology and function when bladder function is normal and the observation period short. Total tapering of the ileal segment did not prove to be advantageous in protecting against hyperchloremic acidosis in this short-term canine study.
