阴囊超声检查对无精子症的诊断价值

Clinical value of scrotal ultrasonography for patients with azoospermia

年1月至2012年3月于我院接受阴囊超声检查的400例无精子症患者的临床资料，总结分析造成无精子症的主要病因及阴囊超声检查的价值。结果400例无精子症患者阴囊超声检查发现因睾丸病变导致无精子症164例（41．O％），其中双侧睾丸发育不良114例（28．5％），双侧隐睾24例（6．0％），双侧睾丸微石症14例（3．5％），双侧睾丸炎12例（3．O％l因输精管道梗阻204例（51．O％），其中双侧附睾炎80例（20．0％），双侧输精管梗阻60例（15．0％），双侧输精管缺如44例（11．0％），双侧附睾体尾部缺如20例（5．O％X其他32例（8．0％）。结论无精子症发生原因较多，睾丸发育不良、附睾炎、输精管缺如及输精管梗阻是主要病因。阴囊超声检查简便、易行、无创，可多次重复检查，有助于寻找病因，为梗阻性无精子症和非梗阻性无精子症的鉴别诊断及临床正确处理无精子症患者提供可靠的影像学依据。

Objective To investigate the clinical value of scrotal ultrasonography for patients with azoospermia. Methods Between January 2009 and march 2012, clinical data of 400 patients with azoospermia were analyzed retrospectively, to study the constinent ratio of the etiopathogenicis of azoosper- mia and the value of scrotal ultrasonography. Results In 400 cases with azoospermia, the diseases of the testis were found in 164 cases （41.0%）, including 114（28.5%） hypogenesis of testicle, 24 （6.0%） cryptorchidism, 14（3.5%） testicular microlithiasis and 12 （3.0%） testitis; the obstruction of deferent duct in 204 cases（51.0%）, including 80（20.0%） epididymitis, 60（15.0%） vas deferens obstructions, 44（11.0%） bilateral absence of vas deferens, and 20（5.0%） absence of epididymal body and tail; and the other etiopathogenicis in 32 cases（8.0%）. Conclusion There are many etiopathogenicis for patients with azoospermia, the main etiopathogenicis are hypogenesis of testicle, epididymitis, bilateral absence of vas deferens and the obstruction of deferent duct. Scrotal ultrasonogaphy is an easy, repeatable, noninvasive method for the patients with azoospermia. It can provide credible ultrasonogaphy evidence for the treatment.
