摘要
目的 探讨经直肠超声（TRUS）在梗阻性无精子症病因诊断中的价值.方法 对328例怀疑存在梗阻性无精子症患者的临床资料进行回顾性分析.对受试者行TRUS检查,同时检测受试者精液量、精子、精液pH值、精浆果糖定量、中性α-葡萄糖苷酶定量、弹性硬蛋白酶定量等指标.结果 328例男性梗阻性无精子症患者中,经TRUS检查,216例（65.8％）患者可以发现比较明确的病因,病因以射精管扩张、精囊腺病变、前列腺中线囊肿多见,分别位列病因的前三位;112例（34.2％）患者超声检查无明显异常;梗阻性无精子症患者精液中未见精子,精液pH ＜7,精浆果糖定量及中性α-葡萄糖苷酶定量值均很低,弹性硬蛋白酶亦处于低水平.结论 男性梗阻性无精子症病因以射精管扩张、精囊腺病变、前列腺中线囊肿多见,TRUS可以比较清晰地观察射精管以及精囊腺等结构异常,可以为远端输精系统梗阻的病因诊断提供重要的参考信息,同时结合精浆生化检查诊断效果更佳.
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 pH,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 pH 〈 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.
