Ectopic ureter is a rare urinary tract abnormality, and is an important cause of urinary incontinence. As the affected kidney is almost hypoplastic or aplastic, it is occasionally difficult to identify an ectopic ureter.
We report the cases of two girls who had ectopic ureters with hypoplastic kidneys. In both cases, they had been diagnosed with hypoplastic kidneys during treatment for urinary tract infection.
On intravenous pyelography, the affected kidneys were not enhanced. Enhanced computed tomography and magnetic resonance imaging revealed hypoplastic kidneys, the ureter on affected side not inserting into the bladder but into the vagina, and a biocornuate uterus. Nephrectomy and ureterectomy were performed based on the diagnosis of ectopic ureter.
The possibility of ectopic ureters in patients with hypoplastic kidneys should be considered. Because urinary tract abnormality often complicates genital organ abnormality, research regarding this phenomenon is necessary.
