[Diagnosis of ectopic ureteral openings in the seminal tract. Value of modern imaging]

We recently observed 3 cases of ectopic ureteric orifice in the seminal tract in patients between the ages of 16 and 42 years. The first case was discovered incidentally, but the other two presented with scrotal symptoms. Intravenous urography, ultrasonography and computed tomography contributed to the diagnosis, but magnetic resonance imaging was the most conclusive, avoiding the need for deferentography in one case. These 3 recent cases allow an evaluation of the respective value of these various imaging modalities.
