亚临床型精索静脉曲张的早期诊断

Early diagnosis of subclinical varicocele

目的:精索静脉曲张是泌尿男科的常见病多发病,占男性不育患者的25%-40%。通过本组病例进行彩色多普勒血液显像(CDFI)检查及其与其他检测方法的比较,证实CDFI检查是亚临床型精索静脉曲张早期诊断的有效方法。方法:本组261例,其中118例行CDFI检查。应用Acuson128型电脑超声仪,探头频率为5MHZ,受检者平卧位,用CDFI检测双侧精索静脉及相关血管的内径、分布、波向、流量,并通过Valsalva试验提高对亚临床型的检出率。结果:返流55例(双侧21例,单纯左侧29例,单纯右侧5例),无返流者63例,左侧Valsalva试验阳性180例,右侧Valsalva试验阳性67例,同时左右侧Valsalva阳性61例,单纯右侧Valsalva阳性6例,单纯左侧Valsalva阳性119例,左右侧Valsalva阴性者75人,左右侧比例为67/180(37.2%)。

Objective:Varicocele is a common and frequently occurring disease of urological andrology, counting for 25%-40% of male sterility patients. After examinations on this group of cases respectively by CDFI and other means, CDFI proves to be an effective method in early diagnosis of subclinical varicocele. Methods: this group of cases is composed of 261 patients, including 118 patients examined by CDFI: We used Acusonl28 computer ultrasonic apparatus with a 5MHZ - frequency probe, and let the examinee lie on his back. By CDFI, we examined the inside diameters, distributions, wave directions and wave volumes of the spermatic and relevant veins of both sides, and increased the detectable rate of subclinical varicocele by Valslva test. Results: 55 patients with regurgitant flow (21 patients at both sides, 29 only at left side, and 5 only at right side) , 63 patients without regurgitant flow; 180 patients are positive in left side Valslva test, while 67 positive in right side Valsalva test, 61 positive in both sides Valsalva test, 6 in only right side test, 119 in only left side test; 75 patients are negative in both side Valsalva test; the rate of the positive in left side test to that in right side test is 67/180(37.2%).
