Azoospermia represents approximately 10% of case of male infertility. Identification of etiological aspects is very important for prognostic and therapeutic evaluation. After the testicular analysis with fine needle aspiration cytology (FNAC) we reviewed the scrotal sonograms of 639 azoospermic patients. In the group of patients with obstructive azoospermia we have found a particular sonographic appearance. This consisted in a normal aspect of the testis, the epididymis have an enlargement, development of cysts and an inhomogeneous echo pattern. However we have found this particular sonographic appearance in same patients with other kinds of azoospermia. In conclusion, scrotal sonogram is a fundamental step in the diagnostic work-up of the azoospermic patient, but it does not allow to distinguish unequivocally patients affected by obstructive azoospermia.
无精子症约占男性不育病例的10%。病因方面的识别对于预后和治疗评估非常重要。在用细针穿刺细胞学检查（FNAC）进行睾丸分析后，我们回顾了639例无精子症患者的阴囊超声检查结果。在梗阻性无精子症患者组中，我们发现了一种特殊的超声表现。其表现为睾丸外观正常，附睾肿大、出现囊肿且回声不均匀。然而，我们在其他类型无精子症的一些患者中也发现了这种特殊的超声表现。总之，阴囊超声检查是无精子症患者诊断检查的基本步骤，但它不能明确区分梗阻性无精子症患者。
