[Application value of elastic ultrasound and contrast-enhanced ultrasonography in evaluating testicular blood supply after blockage of the vas deferens artery]

Objective To explore the application value of elastic ultrasound (EUS) and contrast-enhanced ultrasonography (CEUS) in detecting the changes of testicular blood supply after blockage of the vas deferens artery. Methods This study included 11 cases of microscopic varicocele ligation. We obtained the EUS and CEUS values of the patients before and after blocking the vas deferens artery and analyzed the data by paired comparison. Results After the blockage of the vas deferens artery, the testicular hardness was reduced across the tunica albuginea and within the testis, with Ave decreased from 11.44 ± 2.52 before to 6.21 ± 1.16 after the blockage of the vas deferens artery across the tunica albuginea (P 0.05). Conclusions Elastic ultrasound and contrast-enhanced ultrasonography play important roles in evaluating the changes of testicular blood supply in different states.
