Ectopic ureter associated with renal dysplasia.

Two patients, aged 22 and 68, were admitted for recurrent orchi-epididymitis and septicemia respectively. On digital rectal examination, a right pararectal mass was palpated. CT showed in both patients unilateral renal agenesia with a dilated blind ectopic ureter and an enlarged pseudocystic seminal vesicle. MRI obtained in one patient demonstrated a hyperintense content of the blind ureter and the seminal vesicle. Cross section imaging findings were in agreement with deferentography. Histology confirmed the diagnosis of renal dysplasia, with a blind ectopic ureter, opening in the seminal vesicle.
