The Mitrofanoff principle in continent urinary reconstruction
Abstract
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.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
