A case of ectopic dysplastic kidney and ectopic ureter diagnosed by MRI.

Background: A 14-year-old girl with a solitary right kidney had continuous urinary incontinence.

She was toilet trained at the age of 2 years, had a normal voiding pattern, and had no history or family history of incontinence.
