ABSTRACT

Objective:

To investigate the values of CT angiography (CTA) and color Doppler ultrasound in the diagnosis and etiological screening of varicocele (VC).

Methods:

Ninety-seven patients with VC diagnosed by the Department of Urology, Central South University Xiangya School of Medicine Affiliated Haikou Hospital from May 2016 to December 2017 were retrospectively included. The CTA and color Doppler ultrasonographic data of 194 spermatic veins (including 116 varicocele veins) were analyzed. Paired t test was used to compare the mean diameter of spermatic veins at the root of scrotum measured by CTA and color Doppler ultrasound. McNemar test was used to compare the sensitivity and specificity of CTA and color Doppler examination for VC, and χ 2 or Fisher exact probability was used to compare the detection rate of CTA and color Doppler examination in screening the etiology of VC.

Results:

The average diameters of scrotal root of spermatic veins by CTA and color Doppler ultrasonography were (2.9±0.6) and (3.0±0.6) mm for VC cases, with no significant difference found( t=0.885, P=0.381). According to the diagnostic VC standard of color Doppler ultrasound (diameter>2 mm), no significant difference was found between CTA and color Doppler ultrasound in the sensitivity [95.69%(111/116) vs. 100%(116/116)] and specificity [100%(78/78) vs. 100%(78/78)] in the diagnosis of VC. The etiological detection rate of CTA in 97 patients with VC was significantly higher than that of color Doppler ultrasound ( P<0.05).

Conclusions:

Both CTA and color Doppler ultrasound have high sensitivity and specificity in the diagnosis of VC. CTA has a higher etiological detection rate in etiological screening of VC than color Doppler ultrasound.
