High-frequency (20 MHz) ultrasound probe placed on the spermatic cord to detect blood flow in millimeter-scale vessels.
How it is used
Identifies and helps preserve the testicular artery, distinguishing it from veins, during subinguinal microsurgical varicocelectomy and vasectomy reversal (vasovasostomy).
Clinical tip
Its intraoperative use significantly increases the number of arteries identified and preserved during varicocelectomy.
