Intermittent Urinary Incontinence Secondary to Inverted-Y Ureteral Duplication With Perianal Ectopia.

Inverted-Y ureteral duplication is one of the rarest anomalies of ureteral branching, which has been found to be more prevalent in females. Females commonly present with urinary incontinence often associated with distal limb ectopia to the bladder neck, uterus, or vagina. We present the case of a 7-year-old female with intermittent urinary incontinence who was found to have an inverted-Y ureteral duplication with perianal ectopia. We highlight the role of magnetic resonance urography in the evaluation of females with urinary incontinence and a normal renal/bladder ultrasound who are refractory to behavioral therapy.
