睾丸微结石的超声诊断及与男性不育的关系

Testicular Microlithiasis:Ultrasonic Diagnosis and Correlation with Male Infertility

目的:探讨睾丸微结石(TM)的超声声像图表现及其与男性不育症的相关性。方法:应用高分辨率二维超声常规检查1198例阴囊疾病患者。结果:其中男性不育患者379例,TM检出21例(5.54%),阴囊内其他疾病患者819例,TM检出12例(1.47%)。TM与男性不育相关(r=0.115,P<0.01),TM在男性不育中发病率显著高于阴囊内其他疾病患者(P<0.05)。TM超声声像图表现为于睾丸实质内可见稀疏?散在或密集分布的强光点,直径在1mm左右,不伴有声影。结论:TM超声声像图特征明显,易于明确诊断;TM与男性不育存在一定相关性。

Objective ： To study the sonographic appearance of testicular microlithiasis （TM） and its correlation with male infertility. Methods ： We conducted high-resolution 2D ultrasound examination for 1 198 patients with scrotal diseases, including 379 with infertility and 819 with other testicular diseases. Results： TM was found in 21 of the infertile men （5.54%） and 12 of the other 819 fertile patients （ 1.47% ）. TM was correlated with male infertility （ r = 0.115, P 〈 0.01 ）, with a higher incidence in the infertile patients than in patients with other testicular diseases （P 〈 0.05）. Sonography of TM showed high-echo dots in the testicular parenchyma, sparse, sporadic or conferred, about 1 mm in diameter and without shadow. Conclusion ： The sonographic appearance of TM, with its obvious features, is conducive to the definite diagnosis of the disease. TM is correlated with male infertility. Natl J Androl,
