title: Ileal segment replacement of ureter. II. Dynamic characteristics of refluxing, nonrefluxing, and totally tapered ileal ureter.
abstract: The pressure characteristics and cinefluoroscopic appearances of a refluxing, nonrefluxing, and totally tapered ileal " neoureter " were compared in 22 dogs with normal bladder function. The totally tapered ileal segment with a reflux preventing ileovesicostomy simulates normal ureteral peristalsis most closely on cinefluoroscopic evaluation. Pressure gradients across the ileovesical junction though were similar in refluxing and nonrefluxing ileovesicostomies , as well as in totally tapered ureters.
