摘要
目的 探索婴幼儿的健侧睾丸长径值对患侧未触及隐睾发育状况的预测价值研究。方法 本研究回顾性随机选取于2014年1月至2014年12月期间就诊的330例患儿病例,比较腹腔内隐睾（n1=116）、睾丸萎缩缺如（n2=112）与正常睾丸（n3=102）患儿的健侧睾丸长径差异;通过ROC曲线分析,得出健侧睾丸长径对患侧睾丸萎缩缺如判定的最佳诊断界值。结果 3组之间患儿的睾丸长径有统计学差异（H=165.67,P〈0.001）;ROC曲线分析结果,健侧睾丸长径对患侧睾丸萎缩缺如有较强的判定能力,曲线下面积（AUC）=0.793（95%CI：0.734-0.853）,其临床判断值为1.7cm,其灵敏度为95.5%,特异度为95.4%,阳性预测值为67.86%,阴性预测值为78.45%。结论 患侧睾丸萎缩缺如的患儿的健侧睾丸长径明显大于腹腔内隐睾及正常睾丸的患儿。当患儿单侧睾丸未触及健侧睾丸长径大于等于1.7cm时,患侧很大程度上出现睾丸萎缩缺如的情况。临床上可将1.7cm作为的一个简单量化标准,来初步预测单侧睾丸未触及的患儿是否发生睾丸萎缩缺如。
Objective The purpose of this study was to explore the best diagnostic standards among abdominal cryptorchidism children in clinical. Methods This study was retrospectively and randomly selected 330 cases from 2014 January to 2014 December who came to Wuhan children hospital, and compared the differences among three groups （n1=116,n2=112, n3=102）.In addition,optimum value was analyzed byROC curve. Results Among the three groups,there were significant differences in testis size （H=165.67, P〈0.001 ） . Using ROC curve to analyze the contralateral testis length of testicular atrophy of judging ability strong, the area under the curve （AUC） = 0.793 （95%CI： 0.734-0.853）, the clinical diagnosis value of 1.7cm, the sensitivity was 95.5%, specificity was 95.4%, the positive predictive value was 67.86% and the negative predictive value was 78.45%. Conclusion The results of this study found that length to diameter of infants suffering from atrophy of testis and absent contralateral testis was significantly larger than that of abdominal testis and normal testis. What＇ s more, the ROC curve analysis show that the status of ipsilateral testicular atrophy were largely happened when the boys＇ unilateral testicular cannot be touched and length of contralateral testis is greater than or equal to 1.7cm. Therefore, 1.7cm as a simple quantitative criteria, can be used to predict whether infants had happened testicular atrophy.
