超声与CT在诊断隐睾及其恶变中的运用

The Use of Ultrasound and CT in the Diagnosis of Cryptorchidism and Its Malignant

目的:探讨彩色多普勒超声及CT在诊断隐睾及其恶变中的临床应用价值,指导临床如何选择有效、经济、无创定性诊断的方式。方法:笔者对近年来检查的45例患者51个隐睾分别行超声及CT检查,并与手术及部分病理结果进行对照、分析。结果:45例患者51个隐睾超声检出45个(检出率88.2%),其中恶变5个,超声检出4个(检出率80.0%)。CT检查:51个隐睾CT检出43个(检出率84.3%),其中恶变5个,CT检出5个(检出率100%)。其中腹腔内隐睾14个,超声检出11个(检出率78.5%),CT检出13个(检出率92.8%)。超声和CT在诊断隐睾及其恶变中的检出率比较差异无统计学意义(P>0.05)。结论:彩色多普勒超声检查隐睾具有准确性高、检查方便、费用低及无创伤等优点,为诊断隐睾症的首选方法。对腹腔内隐睾及隐睾恶变者,要配合CT检查,以提高诊断检出率。

Objective：To evaluate the clinical application of color doppler ultrasound and CT in the diagnosis of cryptorchidism and its malignant transformation,to provide effective,economic and non-invasive way for qualitative diagnosis.Method：Forty-five patients with 51 cryptorchidism were examined by ultrasound and CT in recent years. Their imageological examinations were compared with surgical and pathological results respectively. Result：In 51 cryptorchidism ,45 cryptorchidism were detected by ultrasound,with the detection rate of 88.2%. Among those cases,4 of 5 malignant transformations were detected by ultrasound（detection rate 80.0%）. In contrast,43 out of 51 cryptorchidism were detected by CT examination（detection rate 84.3%）,of which 5 malignant cases were detected by CT with the accuracy rate of 100%. Among total 14 celiac cryptorchidism cases,11 cases（78.5%）were detected by ultrason examinations,while 13 cases（92.8%）were detected by CT scan. There was no significant difference between ultrasound and CT examination as for the detection rate in the diagnosis of cryptorchidism and its progression（P〉0.05）. Conclusion：Compared with CT,the color doppler ultrasound examination are high accuracy,easier to check,low-cost and non-invasive,therefore it is the preferred method in the diagnosis of cryptorchidism. However,in order to improve the diagnosis rate,ultrasound examination should be recommended to cooperate with CT for celiac cryptorchidism patients or patients with cryptorchidism malignant transformation.
