New techniques for construction of efferent conduits based on the Mitrofanoff principle.
Presently, urinary diversion with continence mechanisms based on the Mitrofanoff principle is frequently used. For its construction, the critical issue is related to the choice of efferent conduit; the most widely used are the appendix and the tapered ileum. Here, we present two alternative techniques for construction of tubes applicable to the same function. Ten dogs underwent operations with two different types of tubes constructed through transversal tubularization of small segments of ileum. These tubes were implanted in the bladder. The dogs were followed up for 30 days, during which all were continent. Their tubes were easily catheterized. The techniques described met the criteria defined for an efferent tube to be used according to the Mitrofanoff principle.
