目的:探讨放射性核素99mTc阴囊血池显像(RSI)技术诊断亚临床型精索静脉曲张(SVc)的价值。方法:本组53例不育1年以上病史、精液分析异常的男性患者接受RSI检查及彩色双功能多普勒显像(CDFI)检查,经RSI检查由计算机计算两侧阴囊血池指数值(SBPI),从而确定有无亚临床型精索静脉曲张,与CDFI检查进行对照分析。结果:RSI诊断SVc相对于CDFI的灵敏度为92.6%,特异度为96.2%。结论:在男性不育的病因筛选中,RSI技术是诊断亚临床型精索静脉曲张的简单安全、有效、无创、客观、准确的方法。
Objective: To investigate the value of radionuclide 99mTc scrotal blood pool imaging (RSI) in the diagnosis of subclinical varicocele (SVc). Methods: Fifty-three male patients with infertility over 1 year history and abnormal semen analysis underwent RSI and CDFI. The index of scrotal blood pool index SBPI) to determine the presence or absence of subclinical varicocele, and CDFI examination for control analysis. Results: The sensitivity of RSI in diagnosing SVc to CDFI was 92.6% and the specificity was 96.2%. Conclusion: RSI is a simple, safe, effective, non-invasive, objective and accurate method for the diagnosis of subclinical varicocele in the screening of male infertility.
