The Mitrofanoff principle in continent urinary reconstruction.
Continent urinary diversion has increasingly become important for treating children and adults with urinary tract pathology that cannot be managed by direct reconstructive techniques. The Mitrofanoff principle, a term that has become synonymous with the flap valve mechanism for promoting the unidirectorial flow of a fluid medium, is a recapitulation of nature's design for the competent ureterovesical junction. Construction of a catheterizable channel using this principle can be performed with a variety of tissues and serves well as a continence mechanism for either the native bladder or intestinal reservoirs. In addition to its utility in managing urinary incontinence, implantation of a catheterizable channel into the cecum can be used to manage fecal incontinence in patients with neurogenic bowel dysfunction.
