The horseshoe kidney is the fusion abnormality of kidney, occuring in approximately 2.5 % of the general population. This anomaly is accompained by a high rate of ureteropelvic junction obstruction. Herein, we present a horseshoe kidney accompained by ureteropelvic junction obstruction, in a 50-year-old man. The purpose of this report was to evaluate the use of multi-detector row computed tomography scan to obtain three-dimensional images of the pelvicaliceal system and vascular structures when considering endopyelotomy as a treatment option.
