•In most patients, the bladderneck is competent, and the patients who require catheterization remain dry between voids. If catheterization is not performed, overflow incontinence occurs.
•In those with non-competent bladderneck or nonexisting bladder neck, urinary diversion, such as a Mitrofanoff procedure, with bladder neck tightening may be needed.
