Abstract
PURPOSE: In 1981 Mitrofanoff presented a procedure to create a continent urinary stoma for intermittent catheterization. Since then, several other methods have been introduced, including the Yang-Monti ileovesicostomy. The length of these ileovesicostomies is limited by the circumference of the bowel segment used, which is inadequate in some cases. We developed a procedure to double the length of the Yang-Monti ileovesicostomy using a single section of bowel. MATERIALS AND METHODS: A 3.5 cm. section of ileum is isolated on its mesentery. The bowel is divided into 2 segments for 80% of its circumference, leaving the bowel intact over the mesentery. Each ring of bowel is then divided adjacent to the mesentery but on opposite sides, allowing the bowel to be unfolded and reconfigured in a single long strip that may then be tubularized. The blood supply to the tube is excellent and it is in the center of the reconfigured ileum. The ends may be trimmed or widely spatulated as necessary. RESULTS: We have performed this procedure in 8 patients. The resulting ileovesicostomy created from a 3.5 cm. section ofileum is 10 to 14 cm. long and accepts a 12F catheter. A larger tube may be created from a longer piece of ileum. All patients are dry and they perform catheterization easily. CONCLUSIONS: This form of ileovesicostomy allows the creation of a long bowel tube that is easily catheterized. The longer length of the tube increases application of the continent stoma principle to more patients and enables reconstruction to be performed with optimal placement and without tension.
