Hypospadias repair

Hypospadias repair is surgery to correct a defect in the opening of the penis that is present at birth. The urethra (the tube that carries urine from the bladder to outside the body) does not end at the tip of the penis. Instead, it ends on the underside of the penis. In more severe cases, the urethra opens at the middle or bottom of the penis, or in or behind the scrotum.

Description

Hypospadias repair is done most often when boys are between 6 months and 2 years old. The surgery is done as an outpatient. The child rarely has to spend a night in the hospital. Boys who are born with hypospadias should not be circumcised at birth. The extra tissue of the foreskin may be needed to repair the hypospadias during surgery.

Before surgery, your child will receive general anesthesia. This will make him sleep and make him unable to feel pain during surgery. Mild defects may be repaired in 1 procedure. Severe defects may need 2 or more procedures.

The surgeon will use a small piece of foreskin or tissue from another site to create a tube that increases the length of your son's urethra. Extending the length of the urethra will allow it to open at the tip of the penis.

During surgery, the surgeon may place a catheter (tube) in the urethra to make it hold its new shape. The catheter may be sewn or fastened to the head of the penis to keep it in place. It will be removed 1 to 2 weeks after surgery.

Most of the stitches used during surgery will dissolve on their own and will not have to be removed later.

Why the Procedure is Performed

Hypospadias is one of the most common birth defects in boys. This surgery is performed on most boys who are born with the problem.

If the repair is not done, problems may occur later on such as:

  • Difficulty controlling and directing urine stream
  • A curve in the penis during erection
  • Decreased fertility
  • Embarrassment about appearance of penis

Surgery is not needed if the condition does not affect normal urination while standing, sexual function, or the deposit of semen.

Risks

Risks for this procedure include:

  • A hole that leaks urine (fistula)
  • Large blood clot (hematoma)
  • Scarring or narrowing of the repaired urethra

Before the Procedure

The child's surgeon may ask for a complete medical history and do a physical exam before the procedure.

Always tell the health care provider:

  • What medicines your child is taking
  • Drugs, herbs, and vitamins your child is taking that you bought without a prescription
  • Any allergies your child has to medicine, latex, tape, or skin cleaner

Ask the child's provider which drugs your child should still take on the day of surgery.

On the day of the surgery:

  • Your child will most often be asked not to drink or eat anything after midnight the night before surgery.
  • Give your child any drugs your provider told you to give your child with a small sip of water.
  • You will be told when to arrive for the surgery.
  • The provider will make sure your child is healthy enough for surgery. If your child is ill, the surgery may be delayed.

After the Procedure

Right after surgery, the child's penis will be taped to his belly so that it does not move.

Often, a bulky dressing or plastic cup is placed over the penis to protect the surgical area. A urinary catheter (a tube used to drain urine from the bladder) will be put through the dressing so urine can flow into the diaper.

Your child will be encouraged to drink fluids so that he will urinate. Urinating will keep pressure from building up in the urethra.

Your child may be given medicine to relieve pain. Most of the time, the child can leave the hospital the same day as the surgery. If you live a long way from the hospital, you may want to stay in a hotel near the hospital for the first night after the surgery.

Your provider will explain how to take care of your child at home after leaving the hospital.

Outlook (Prognosis)

This surgery lasts a lifetime. Most children do well after this surgery. The penis will look almost or completely normal and function well.

If your child has a complicated hypospadias, he may need more operations to improve the penis appearance or to repair a hole or narrowing in the urethra.

Follow-up visits with a urologist may be needed after the surgery has healed. Boys will sometimes need to visit the urologist when they reach puberty.
