We report on a case of an ectopic ureter associated with a duplicated collecting system in a 6‐month‐old girl. Results of conventional imaging and endoscopic studies, including intravenous pyelography, ultrasonography of the kidneys, cystoscopy, vaginoscopy, and vaginogram, were unremarkable. An ectopic ureter, extending from a poorly functioning upper pole of the ipsilateral duplicated kidney to its vaginal opening, was visible on the magnetic resonance‐urogram. The imaging time was not extensive, and the need for patient sedation was minimal. Respiratory motion and intestinal gas did not interfere with the quality of the images. Magnetic resonance‐urography may possibly be used as a primary diagnostic method for this anomaly when it is not detected by standard imaging techniques, or as a noninvasive substitute for some interventional studies in infants.
