低促性腺激素性性腺功能减退的患者中Prader睾丸测量器误差较大(1)
摘要：目的 睾丸体积的大小与其功能关系密切，关于Prader睾丸测量器的准确性有争议。本文在低促性腺激素性性腺功能减退(HH)的患者中，对比Prader睾丸测量器及超声两种方法测量睾丸体积的结果，以评估Prader睾丸测量器测量睾丸体积的准确性及其影响因素。方法 对27名低促性腺激素性性腺功能减退的男性患者(平均年龄25±5岁)进行性激素的治疗并长期随访，患者治疗前及每次3个月复诊都接受Prader睾丸测量器及超声两种方法测量睾丸体积，共得到87次测量结果，双侧睾丸一共174组数据。结果 Prader睾丸测量器及超声两种方法测量的睾丸平均体积分别为(7.5±3.6)ml、(3.0±2.1)ml。两种测量方法之间具有相关性(r=0.738，P<0.001)。但是Prader测量器测得的睾丸体积平均超过了超声测量结果的(4.5±2.7)ml，相当于超声测量结果的3.2倍。睪丸体积越小，Prader测量器测量结果的误差越大。结论 在HH患者中，使用Prader睾丸测量器测量睾丸体积的误差较大，临床上应仅作为参考。Prader测量器测得的睾丸体积超过实际体积。睾丸体积越大，Prader测量器测得的睾丸体积越接近实际体积。

Abstract：Objective The relationship between the size of testicular volume and function closely，controversial about the accuracy Prader orchidometer. In hypogonadotropic hypogonadism(HH)in patients with contrast Prader orchidometer and ultrasound two methods of measurement of testicular volume results in accuracy and influencing factors of evaluation of Prader orchidometer the measurement of testicular volume.Methods 27 male patients with lower gonadotropin gonadal hormone of hypogonadism(mean age 25±5 years)for the treatment of sex hormone and long-term follow-up of patients before treatment and every 3 months to accept Prader orchidometer and two ultrasonic method for the measurement of testicular volume，a total of 87 results a total of 174 sets of data，bilateral testes.Results Prader orchidometer and ultrasound measurement of two methods respectively.The average volume of testis(7.5±3.6)ml，(3.0±2.1)ml.Two measurement with the correlation between methods (r=0.738，P<0.001).But Prader is measured by the measurement of testicular volume averaged over the ultrasonic measurement results(4.5±2.7)ml，equivalent to 3.2 times the ultrasonic measurement results.The testicular volume is small，the error of measurement results of Prader measurement instrument is greater.Conclusion In the HH patients，the use of Prader testicular test instrument to measure the testicular volume error is relatively large，should only be used as a reference.The testis volume measured by the Prader gauge exceeds the actual volume.The greater the testis volume，the closer the test volume of the testis to the actual volume., http://www.100md.com(王宇 王伟 季文 何薇 李延兵 廖志红)
