摘　　要：目的探讨超声对儿童睾丸微石症(TM)的诊断价值。方法回顾分析695例儿童阴囊超声检查结果,记录TM患儿的睾丸微石数目、睾丸体积、睾丸内血流指标等,并与正常儿童对比分析。结果 695例儿童中检出TM 16例,检出率2.3%,表现为双侧14例,单侧2例。2例充满型患儿睾丸体积较正常儿童减小,血流分布减少,睾丸动脉峰值流速减低(P<0.05),睾丸动脉阻力指数与正常儿童比较差异无统计学意义;1例隐睾伴TM患儿睾丸体积较对侧明显偏小;余13例TM患儿与正常儿童睾丸各参数比较差异均无统计学意义。结论超声可确诊TM,明确分级,对TM转归随访意义重大。充满型TM可致睾丸发育不良,持续随访可为成人TM不育提供资料。Objective To explore the diagnostic value of children ’s testicular microlithiasis（TM） by color Doppler ultrasound. Methods Data of 695 cases of children’s scrotal ultrasound images were enrolled and analyzed,records of TM number,testicular volume,testicular blood flow index,etc.,the results was compared with normal children. Results Sixteen cases of TM were found in 695 children,the detection rate was 2.3%,characterized by bilateral 14 cases,2 cases of unilateral.Two cases of full filled TM,their testicular volume were smaller than normal children,the testicular artery peak flow rate was obviously reduced（P 〈 0.5）,no obvious difference were found for the blood flow distribution,testicular artery RI between TM children and normal children.The testicular volume of TM child with cryptorchidism was significantly smaller.No obvious difference of blood parameters were found between the rest 13 cases of TM children and normal children. Conclusion Ultrasonography is able to not only diagnose the TM correctly,but also classify them into degrees.The color Doppler ultrasound of great significance for TM children. Full filled TM may cause testicular dysplasia,continuous follow-up is helpful to diagnose adult TM infertility.
