A varicocele is a widening of the veins along the cord that holds up a man’s testicles (spermatic cord).
A varicocele forms when valves inside the veins along the spermatic cord prevent blood from flowing properly. This causes the blood to back up, leading to swelling and widening of the veins. (This is essentially the same process that leads to varicose veins, which are common in the legs.) Varicoceles usually develop slowly. They are more common in men ages 15 – 25 and are most often seen on the left side of the scrotum. The sudden appearance of a varicocele in an older man may be caused by a kidney tumor, which can block blood flow to a vein. This is more common on the left side than the right.
A jock strap (scrotal support) or snug underwear may help relieve the pain or discomfort. If pain continues or other symptoms occur, you may need further treatment. Surgery to correct a varicocele is called varicocelectomy. You will leave the hospital on the same day as your surgery. During this procedure, you will receive some type of numbing medication (anesthesia). The urologist will make a cut, usually in the lower abdomen, and tie off the abnormal veins. Blood will now flow around the area into normal veins. Keep an ice pack on the area for the first 24 hours after surgery to reduce swelling.
An alternative to surgery is varicocele embolization. This method is also done without an overnight hospital stay. It uses a much smaller cut than surgery, so you will heal faster. A small hollow tube called a catheter (tube) is placed into a vein in your groin or neck area. Using x-rays as a guide, the health care provider moves the tube into the varicocele. A tiny coil passes through the tube into the varicocele. The coil blocks blood flow to the bad vein, and sends it to normal veins. After the procedure, you will be told to place ice on the area and wear a scrotal support for a little while.
Infertility is a complication of varicocele. Complications from treatment may include:
