Retroiliac ectopic ureter opening to the seminal vesicle

To describe a case of right retroiliac ectopic ureter opening into the seminal vesicle, an uncommon congenital malformation. This anomaly was diagnosed in a 24-year-old male with recurrent acute right epididymitis based on the clinical, ultrasound and CT findings. Cystoscopy and IVP provided no additional information. Surgical exploration showed right renal agenesis and a retroiliac ectopic ureter opening into a dilated right seminal vesicle. These structures were resected. Patient evolution was satisfactory with no recurrence of the infective episodes. Diagnosis of this anomaly is based on clinical suspicion and the findings of the diagnostic imaging techniques. Surgical exploration, which is only required in symptomatic patients, will establish the correct diagnosis and treatment.
