Several congenital anomalies of the urinary tract are reported in the literature. Ureteral duplication is among the most frequent and may be either complete or incomplete. Here we describe the case of a 35-year-old male patient who presented with an acute urinary retention. Ultrasound examination showed significant hydronephrosis, and it was followed by a multidetector computed tomography (MDCT) without contrast medium. This examination showed the evidence of an incomplete double ureter upstream dilated, due to a calculus that occluded both ureters at the junction, arranging itself over them (“saddle” calculus). MDCT is a highly-sensitive examination technique for the detection and grading evaluation of urinary diseases.
