Diagnostic magnetic resonance-urography in an infant girl with an ectopic ureter associated with a poorly functioning segment of a duplicated collecting system

Int J Urol. 1997 May;4(3):314-7. doi: 10.1111/j.1442-2042.1997.tb00198.x.


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.
