Etiology screening role of transrectal ultrasonography in male obstructive azoospermia infertility

Abstract

Objective To study etiology screening role of transrectal ultrasonography in male obstructive azoospermia infertility. Methods The clinical data of 328 cases who suspected of being obstructed sperm disease were retrospectively analyzed. TRUS detection was conducted, at the same time, the sperm amount, sperm and semen p H, pure berries quantitative, neutral sugar alpha glycosidase enzymes quantitative, elastic hard protease were tested. Results In 328 cases with male obstructed no sperm,by TRUS detection results,216 cases(65.8%)could find the causes, ejaculatory duct expansion, seminal vesicle gland lesions, prostate midline cyst were the top three causes respectively; 112 patients(34.2%) had no obvious abnormal ultrasonic testing. Sperm was not seen in semen of obstructive azoospermia patients and semen p H<7,pure berries sugar quantitative and quantitative value neutral alpha glycosidase enzymes were very low,hard elastic protease was low. Conclusion The main causes of obstructive azoospermia were ejaculatory duct expansion, seminal vesicle gland lesions, prostate midline cyst, sperm TRUS detection used for diagnosis of high sensitivity, and easy to operate, noninvasive, and combined with seminal plasma biochemical examination, the diagnostic effect is much better.
