Noninvasive imaging procedures in the diagnosis and therapy control of varicoceles. I: Sonography and thermography in the diagnosis of varicoceles

Abstract

69 patients with clinically suspected varicoceles were examined thermographically and sonographically prior to testicular phlebography. The combination of sonography and thermography permitted precise differentiation into normal findings (7%), left-sided varicoceles (86%) and bilateral varicoceles (7%). Thermography was advantageous with an accuracy of 97.3%. Sonography had an accuracy of 90.5%. No clear correlation was found between varicocele size and degree of hyperthermia. The combination of sonography and thermography affords a high degree of accuracy in the diagnosis of varicoceles, including subclinical and infantile varicoceles.
