Abstract: | A technique for undiverting a colonic conduit of limited capacity and with short ureters is described. The colonic segment of the conduit and an additional segment of small bowel are patched together to form a low pressure cystoplasty of large capacity. This technique incorporates 3 principles that are believed to be important in reconstructing any type of cystoplasty: large capacity, increase in diameter and disruption of the strong circular muscle layer of the bowel by detubularization. |
