Ultrasound
What is a vasectomy?
A form of male birth control where the supply of sperm to the semen is cut surgically.
What is the ultrasound appearance of the vas deferens postvasectomy?
Fluid-filled tubularly dilated structures that are non-vascular on color/power flow Doppler interrogation.
What are some changes that may occur at the epididymis post-vasectomy?
Spermatoceles formations present as small, medium, or large cysts. Also, the epididymal parenchyma may be oedematous with inhomogeneous echogenicity due to engorgement.
The right and the left vas deferens are mildly engorged with clear fluid content. Focal medially disrupted/severed areas are demonstrated at the vas deferens (measuring approximately 0.80 cm in length on the right) post-exploration vasectomy.
Simple sub-centimetre thin-walled clear fluid-filled cysts eccentrically located at the right epididymal head, and at the left epididymal head, and body are noted. There are mild bilateral scrotal sacs fluids (<5ml) on either side. Both testicles are within the scrotal sacs and maintain their sizes, shapes, and parenchymal echo/vascular pattern.
