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.
