Abstract：Objective:To evaluate the diagnosis and surgical treatment of obstructive azoospermia.Methods:We analyzed the clinical data of 56 cases of obstructive azoospermia,43 of them with ejaeulatory duct obstruction(EDO),and the other 13 suspected of epididymal obstruction.The diagnostic methods included Semen analyses.measurement of fructose and neutral α-glucosidase in the seminal plasma,transrectal ultrasonography(TRUS),and vasegraphy when necessary.The 43 patients with EDO were treated by transurethral resection of the ejaculatory duct(TURED),and 11 of the 13 cases of suspected epididymal obstruction were confirmed by scrotal exploration and underwent either bilateral or unilateral vasoepididymostomy.The patients were followed up for 3-51 months for postoperative semeu quality and impregnation.Results:Of the 43 azoospermia patients with EDO treated by TURED,36(83.7%) showed impmved semen parameters and 11(25.6%)achieved pregnancies.Among the 11 cases of azoospermia with confirmed epididymal obstruction treated by vaseepididymostomy,6(54.5%)had sperm in the semen assay and 3(27.3%)achieved pregnancies.Conclusion:Semen analyses,measurement of fructose and neutral α-gheosidase in the seminal plasma,TRUS and vasography are important diagnostic methods for obstructive azoospermia.TURED is effective for azoospermia with EDO,while vasoepididymostomy is preferable for the treatment of azoospermia with epididymal obstruction.
