We analyze the hemodynamics in the testis of the patient with varicocele by contrast ultrasound sonography using perflubutane (Sonazoid). From a provided result, we inspect a conventional criteria of the varicocele using B-mode and color Doppler imaging.
Others
observational study
1:Evaluation by B-mode and color Doppler imaging
the size of the testis, the spermatic cord vein diameter, the grade of varicocele
2:Evaluation by the contrast ultrasound sonography
TTP(time to peak arterial circulation), MTT(mean transit time), artery circulation time (wash-in), venous circulation time (wash-out)
Single arm
Non-randomized
