摘　　要：目的　探讨超声检查在儿童睾丸微石症 (TM )诊断中的应用。方法　回顾分析 4 5 3例就诊儿童中 8例睾丸微石症 (TM)的超声表现、病理结果、临床表现。结果　儿童TM表现为双侧或单侧睾丸实质内、≤ 2mm、散在的、无声影的强光点 ;分为部分型与完全型。睾丸大小与正常者无统计学差异 (P >0 .0 5 )。病理改变为曲细精管内多发、单个板层状钙化体。 7例随访无恶性变。结论　儿童TM经超声检查确诊 ,无特异性症状及体征。发病率 1.8%。在先天性睾丸异常者中发生率较高( 2 .5 % )。定期超声检查有助于客观评价儿童TM的转归。Objective To study the application of ultrasonography in diagnosing testicular microlithiasis (TM) in children.Methods The ultrasound feature,clinical presentation and pathology were reviewed in 8 children with a mean age of 6.9 years. They were incidentally discovered from a group of 453 children.Results The ultrasound feature of TM included unilateral or bilateral,≤2?mm,diffuse (or asymmetric), punctate, nonshadowing, hyperechoic foci within the testicular parenchyma. The testicular size was not statistically different from those of normal children ( P > 0.05 ).Testicular pathology was multiple and diffuse laminated calcification inside the seminiferous tubules. To date, no testicular tumor has developed during follow up. Conclusions TM can be diagnosed by ultrasonography. It is not a distinctive clinical condition. There is a high incidence of TM in patients with congenital testicular anomaly ( 2.5% ) as compared to the normal ( 1.8% ). A regular testicular ultrasound examination is advocated for the children of TM.
