Nonrefluxing colonic conduit: efficiency and complications of ureterocolic anastomosis.

The efficiency of and complications in 65 cases of colonic conduit have been studied (64 cases of bladder exstrophy and 1 case of cloacal exstrophy). For the ureterocolic reimplantation, we employed the Leadbetter technique and a modified kelalis technique. The results after 1-12 years in 128 renoureteral units showed 28 complications (21 obstruction and 7 refluxing units). Other types of complications have been observed and reported in this work. The high incidence of obstruction was probably due to the long submucous tunnel in the ureterocolic reimplantation. We believe that the sigmoidal conduit is an adequate method for temporary or permanent diversion.
