摘　　要：目的 探讨超声弹性成像(Ultrasound Elastography,UE)应变率比值(Strain Rate Ratio,SR)法在小儿睾丸鞘膜积液中的应用价值。方法 选取50例1~5岁单侧睾丸鞘膜积液患儿为研究对象,分为术前组和术后组,另选取50例1~5岁健康儿童为对照组,分别行二维超声、彩色多普勒血流显像及UE定量分析检查,比较术前组、术后组及对照组睾丸体积(Testicular Volume,TV)、形态、血流分布、睾丸内动脉阻力指数(Resistance Index,RI)以及双侧睾丸SR,探讨术前组SR与各项指标的相关性。结果 术前组患侧睾丸内动脉RI高于对侧及对照组,差异有统计学意义(P<0.05),术后RI较术前降低,差异有统计学意义(P<0.05)。术前组、术后组及对照组TV组内及两组间比较,差异均无统计学意义(P>0.05)。术前组SR(对侧/患侧)明显高于术后组及对照组,差异有统计学意义(P<0.05),术后组SR(对侧/患侧)与对照组比较,差异无统计学意义(P>0.05)。SR与积液体积、发病时间及睾丸内动脉RI均呈正相关(P<0.001)。结论 UE的SR法可反映鞘膜积液侧睾丸与对侧睾丸间的硬度差异,为临床中检测睾丸硬度、评估术后睾丸恢复情况提供有效的定量评估指标。Objective To investigate the application value of strain rate ratio(SR)method of ultrasonic elastography(UE)in children with testicular hydrocele.Methods Fifty children aged 1-5 years with unilateral testicular hydrocele were selected as the research subjects,and they were divided into preoperative group and postoperative group.Another fifty healthy children aged 1-5 years were selected as the control group.Two-dimensional ultrasound,color Doppler flow imaging and UE were performed for quantitative analysis.Testicular volume(TV),morphology,blood flow distribution,internal testicular artery resistance index(RI)and bilateral testicular SR in preoperative,postoperative and control groups were compared.The correlation between the SR and various indexes in the preoperative group was discussed.Results RI of the internal testicular artery of the affected side of the peroperatine group was higher than that of the contralateral side and control group,the difference was statistically significant(P<0.05),and RI of the postoperative side was lower than that before surgery,the difference was statistically significant(P<0.05).There was no significant difference in TV within and between preoperative group,postoperative group and control group(P>0.05).SR in preoperative group(contralateral/affected side)was significantly higher than that in postoperative group and control group,the difference was statistically significant(P<0.05).There was no significant difference in SR(contralateral/affected side)between the postoperative group and the control group(P>0.05).SR was positively correlated with fluid volume,disease time and internal testicular artery RI(P<0.001).Conclusion The SR method of UE can reflect the hardness difference between lateral testis with hydrocele and the contralateral testis.This method is expected to provide an effective quantitative evaluation index for testing testicular hardness and evaluating testicular recovery after operation in clinic.
