Transurethral resection of cystic and non-cystic ejaculatory duct obstructions.

Ejaculatory duct obstructions are diagnosed in approximately 5% of azoospermic men and can be treated by transurethral resection (TURED) or incision of the ducts. Eight patients with azoospermia and ejaculatory duct obstructions were treated by TURED after clinical examination, semen analysis, biochemical analysis of seminal plasma, endocrine analysis, transrectal ultrasonography and testicular biopsy. In 3/3 cases of cystic and in 3/5 cases of non-cystic obstruction. TURED of the stenosis was possible. During a follow-up of 12 months there was an increase in semen volume and sperm count in 3/3 and 3/5 patients, respectively. No pregnancy was achieved during the period up to 12 months. Clinical symptoms such as haemospermia and pain disappeared in all cases. In our cases and another 98 cases of ejaculatory duct obstructions documented in the literature, men of semen quality improved in 38-60% with a pregnancy rate of men 22-31% after TURED. We conclude that there is a correlation between the aetiology of ejaculatory duct obstructions and success rate of TURED.
