目的:探讨阴囊超声显像在无精子症病因诊断中的应用价值。方法:对96例无精子症患者行阴囊超声检查,将声像图与最终诊断结果进行对比分析。结果:依据声像特征96例患者中35例提示为梗阻性无精子症,61例提示为非梗阻性无精子症,诊断准确率为97.0%。梗阻病例中44.4%的患者可依据声像特征对梗阻病因及部位作出提示,与最终诊断完全符合;非梗阻病例中46.7%的患者可依据声像特征对病因及部位作出提示,诊断准确率为75.0%。其余病例可对病因作出方向性提示,缩小进一步检查的范围。结论:应用阴囊超声显像可对无精子症病因做出诊断或方向性提示,是无精子症患者重要的检查手段。
Objective: To investigate the value of scrotal ultrasound in the diagnosis of azoospermia. Methods: Ninety-six patients with azoospermia underwent scrotal ultrasonography. The sonography and final diagnosis were compared. Results: According to the characteristics of sound and sound, 35 of 96 patients showed obstructive azoospermia, and 61 showed non-obstructive azoospermia. The diagnostic accuracy was 97.0%. 44.4% of the obstructive cases could be prompted according to the characteristics of the sonographic features of the obstruction and the site of the obstruction, which was in good agreement with the final diagnosis. 46.7% of the patients with non-obstructive cases could be prompted with the etiology and location according to the characteristics of sonography. The diagnostic accuracy was 75.0%. The remaining cases can be directional etiology prompted to narrow the scope of further examination. Conclusion: Scrotal ultrasound imaging can diagnose or direct the etiology of azoospermia, which is an important test for azoospermia patients.
