Renal aplastic dysplasia and ipsilateral ectopic ureter obstructing the seminal via: a possible cause of male infertility.

Few cases of unilateral renal agenesis associated with ipsilateral seminal vesicle ectasia or cyst have been reported. Two cases of unilateral renal aplastic dysplasia and ipsilateral ectopic ureter opening in the ejaculatory ducts associated with infertility secondary to bilateral obstruction of the seminal via are reported. Clinical and physical assessment including transrectal ultrasound and magnetic resonance imaging are proposed as a comprehensive algorithm for the diagnostic evaluation of the pelvic cystic masses.
