[The diagnosis and treatment of ureteral enuresis in a girl aged 14 with unexpected explanation of the cause of the disorder--a case report].

In our case report we present the course of diagnosis and treatment of primary urinary incontinence in a girl aged 14. In abdominal ultrasound examination we found features of double renal pelvis on the left side. Intravenous urography confirmed that anatomical variant. Moreover it gave the suggestion of duplicated left ureter. Regarding the clinical data and the results of ultrasonography and urography, we suspected that the symptoms might be connected with the ectopic orifice of one from the left ureters, probably that one associated with the upper renal pelvis. We managed to find this ectopic ureteral orifice in the vaginal vestibule. But when we performed antegrade pyelography through that orifice, we found that it constituted the ending of additional right ureter, which was not imaged in previous examinations. That diagnosis was very unexpected. The child was operated on. During the operation a small, hypoplastic additional right kidney was discovered. That kidney was excised together with the ectopic ureter. The urine incontinence stopped immediately after the operation.
