Abstract:
A 5-year-old girl with a rare anomaly of a single system ectopic ureter draining into the mesonephric duct cyst and ipsilateral crossed fused kidney is presented. Both ureters were catheterized and three dimensional (3-D) images of the urinary tract were reconstructed with helical computed tomographic (CT) data. A mesonephric duct cyst, the right ureter draining into the cyst and an ectopic orifice were well depicted with these images, especially with inferior projection images. 3-D display of helical CT data with a retrograde contrast study is a promising method of obtaining anatomical detail of an ectopic ureter.
