摘要
目的:探讨经直肠超声(TRUS)在男性梗阻性无精子症病因筛查中的作用。方法:回顾性分析我院2007年1月至2009年5月695例男性梗阻性无精子症患者的TRUS的病因诊断结果。结果:695例梗阻性无精子症患者中,TRUS检查发现病变以射精管病变(29.2%)、精囊腺病变(25.4%)以及前列腺中线囊肿病变(18.5%)为主。TRUS检查共发现射精管扩张203例;精囊腺病变177例,其中先天性精囊腺缺如或者发育不全108例,精囊腺扩张51例;另外,TRUS诊断发现前列腺中线囊肿128例,其中75例(58.5%)射精管囊肿,39例(30.5%)苗勒管囊肿。34例患者的梗阻性无精子症可能由于钙化性疾病导致。而153例患者(22.0%)TRUS检查未见明显异常。TRUS在本组梗阻性无精子症患者中,78.0%可以发现比较明确的病因。结论: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。
Objective： To assess the role of transrectal ultrasonography（TRUS） in the etiological diagnosis of male obstructive azoospermia.Methods： We retrospectively analyzed the clinical data and TRUS findings of 695 patients with obstructive azoospemia from January 2007 to May 2009.Results： Concerning the etiology of obstructive azoospemia,the main TRUS findings included ejaculatory duct abnormality（29.2%）,seminal vesicle abnormality（25.4%） and prostate midline cyst（18.5%）.TRUS revealed 203 cases of ejaculatory duct dilation,177 cases of seminal vesicle abnormality（including 108 with absence or agenesis and 51 with dilation of the seminal vesicle）,and 128 cases of prostate midline cyst（including 75 with ejaculatory duct cyst and 39 with Müllerian cyst）.Calcification of the verumontanum or ejaculatory duct was suspected to be the causes of obstructive azoospermia in 34 cases.However,no significant etiological abnormality was found in 153 cases.Obvious etiology was shown by TRUS in 78.0% of the patients.Conclusion： TRUS can clearly display the structural abnormality of the ejaculatory duct and seminal vesicle,and provide important information on the etiology of male obstructive azoospermia.
