To study the fate of a refluxing ureteral stump used as a Mitrofanoff channel (MC) for clean intermittent catheterization (CIC), without reimplantation in augmented bladders. Ten boys and seven girls, 1-14 years old (mean 6.5 years) seen in period 1998-2005, underwent creation of MC using refluxing or potentially refluxing ureters. Concomitant bladder augmentation (BA) was performed for various abnormalities of lower urinary tract, including exstrophy epispadias complex, neurogenic bladder cloaca and posterior urethral valve. The uretero-vesical junction was maintained intact during creation of the MC. Follow-up period ranged from 2-72 months (mean 32.5 months). Satisfactory CIC was possible in 14 children while in two children the stoma became obstructed due to non-usage. Urinary leak via the ureteric MC was seen in only one patient who partially responded to anticholinergic therapy and a shortened CIC interval but this needed to be formally closed subsequently. A refluxing ureter can be used in the creation of a MC without formal reimplantation in the majority of children undergoing BA.
