【Abstract】 Objective To study the use of infrared thermography for the diagnosis of male genital system diseases.Methods Different male genital diseases 39 cases ( 9 hydrocele, 4 acute orchitis, 4 varicocele of spermatic cord, 14 acute epidiymitis and 8 other diseases) were underwent by infrared thermography and 5 cases for therapeutic monitoring, and also compared with ultrasonic and clinical study.Results The maximum and average temperature''s difference between right and left scrotum over 0.5 ℃ was considered as abnormal. The positive detectability rate of infrared thermography in male genital system disease was 51.3%（20/39），the diagnostic concordance rate with ultrasonography was 71.8%（28/39）, whereas the postivie detectability rate of hydrocele, acute orchitis, varicocele of spermatic cord, and acute epidiymitis was 89%，75%，75% and 36% respectively.5 cases used for therapetupic monitoring showed that there was decreased temperature difference after treatment to suggest improvement.Conclusion Infrared thermography is simple and easy to manipulate for the measurement of scrotum temperature. It can be used as a repeated study method, as a screening method for the related testicular and epididymus diseases, and also as a noninvasive method for its therapeutic evaluation and monitoring.
男性生殖系统的各种病变可不同程度地影响阴囊的表面温度，阴囊位于人体下部的体表，应用红外热影像诊断仪定量分析其温度改变情况，可为睾丸和附睾等相关疾病的诊断提供间接的依据。本研究对39例睾丸和附睾等相关疾病进行红外热影像诊断，探讨其在男性生殖系统疾病中的临床应用价值。
1．1 一般资料 患者均来自我院泌尿科门诊，由一位泌尿科医师检查和诊断后转来红外热影像，并在当天同时进行超声显像。男性各类生殖系统疾病共39例，包括鞘膜积液9例，急性睾丸炎4例，精索静脉曲张4例，急性附睾炎14例，其他疾病8例（精索囊肿、精索细胞瘤、睾丸囊肿、附睾结节、前列腺癌、睾丸外伤、性功能低下和左侧睾丸扭转各1例）。39例中有5例（4例鞘膜积液、1例急性睾丸炎）经抗菌、消炎等治疗后进行红外热影像复查1～2次。
1．3 红外热影像诊断标准 正常人左右侧阴囊的温度差值在0.5℃以内（正位的高值温度或平均温度为准），异常者左右侧阴囊的温度差值＞0.5℃为异常。低值温度由于波动较大仅作为参考。红外热影像结果与B超相对照，并参照临床诊断。
2．1 鞘膜积液 9例（左侧、右侧和双侧各3例），8例与超声诊断相符，其表现为急性炎症期温差明显，慢性期温差虽然降低，但温差仍＞0.5℃；另1例双侧鞘膜积液者两侧温差＜0.5℃，阳性检出率为88.9%（8/9）。
