An inguinal (related to the groin) hernia occurs when a part of the intestine protrudes through a weakened spot in the abdominal muscles and into the groin area, while a hydrocele is a fluid-filled sac in the scrotum (the pouch that holds the testes.) Inguinal hernias are more common in boys than girls and tend to occur more often in premature babies.
Inguinal hernias and hydroceles are caused by a malformation of the inguinal canal. Before birth, the inguinal canal connects the abdominal cavity (belly) and a child’s normally descending sexual organs. This channel usually closes before or soon after birth, but if the connection remains open, fluid from the abdominal cavity can be trapped in the scrotum in boys and form a hydrocele.
If the connection is large enough, the intestine may be pushed into this space when a child strains causing a protrusion known as a hernia, which may look like a bulge or a lump in your child’s groin area.
The majority of hydroceles go away by themselves by the time your child is 12 to 18 months old.
However, if your child’s hydrocele is very large, changes in size, or persists, or if the hernia can be seen or felt or causes discomfort in your child, your Nemours pediatric urologist may recommend surgical repair. When the hernia bulges out, it is usually soft and not painful to the touch.
If you notice that your child’s hernia is firm, red or tender, you need to call your doctor right away. With hernias, the intestine can become trapped in the hernial sac and cause serious problems, including injury to the intestines and the blood vessels that supply blood to the testes.
Most inguinal hernia and hydrocele repairs are done on an outpatient basis in the operating room and take about one hour. Your Nemours urologist will explain the surgical procedure to you and answer any questions you may have. Recovery time is generally short and your child may be able to take part in usual play activities in a day or so.

What Can I Do About My Child's Bedwetting?
My 12-year-old son still frequently wets the bed. How can I help him?
Bedwetting, or enuresis, affects many older kids and even teens. Although the chances are good that your son will outgrow the condition, consider talking to your doctor, who can help find possible causes and suggest the best treatment.
Treatment might include behavior modification, the use of a bedwetting alarm, medicine, counseling, and other methods. Most important, knowing that he has the support and understanding of his family can help your son to feel less frustrated or ashamed about wetting the bed.
