In the mother’s womb, a baby boy’s testicles develop inside his abdomen. Shortly before birth, they move down into the scrotum. In about 4 percent of infant boys, this movement does not occur. For half of these babies, movement does occur before age 1. If the testicles do not move down into the scrotum by age 1, the pediatrician and parents must discuss whether or not to use surgery, called an orchiopexy (OR-kee-o-PEK-see), to bring the testicles down into the scrotum.
Undescended testicles may not cause pain, but they may cause swelling or a lump in the groin area (the place where the lower abdomen meets the inner thigh). If not corrected surgically, the undescended testicles may cause infertility and other medical problems later in life, including the development of tumors or hernias. The area is also more vulnerable to injury if not corrected.
The surgery to move the undescended testicle into the scrotum is done under general anesthesia. General anesthesia makes your child’s whole body go to sleep and is needed for the surgery so that his reflexes will be completely relaxed. General anesthesia makes the surgery easier and safer to do because your child will not feel any pain or have any memory of it.
Caudal anesthesia is given with general anesthesia to block pain in the low back, tummy and lower trunk area and provides up to 4 hours of pain relief in that area after the surgery. Caudal anesthesia is usually more successful in younger children. The surgeon may give your child a local anesthetic injection if a caudal injection is unsuccessful or unnecessary.
