What is Hypospadias?

Hypospadias is the most common congenital birth defect of the penis, affecting about 1 in 300 newborn boys. It is the abnormal location of the urethral opening on the penile shaft (usually on the underside of the penis), and is frequently found with other defects like penile curvature and incomplete or hooded foreskin. It can be very mild and purely aesthetic or cause severe functional disorders including mental and social health problems, if not treated early. The majority of boys with hypospadias have no other health problems. Hypospadias are not associated with sexual development disorders.

The pediatric urologists at UT Urology have significant skill and experience in the surgical techniques to repair this defect. The goal of surgery is to create a normal appearing, straight penis with a urethra opening as close to the tip of the penis as possible to allow urination in a standing position. This will allow for a properly directed urinary stream, a straight penis on erection, and a cosmetically acceptable appearance.

What are the Risk Factors for Hypospadias?

  • 20% of cases have an affected relative
  • Low birth weight
  • Twins or triplets
  • In Vitro Fertilization is associated with an increased risk of hypospadias
  • Undescended testes are associated with hypospadias

What Causes Hypospadias?

  • The cause is generally poorly understood
  • It results from incomplete development of the urethra in utero
  • Genetic factors play a role in cases where there is a family history

How Is Hypospadias Diagnosed?

Hypospadias is present at birth. The diagnosis is generally made during physical examination of your newborn at birth. You will be asked if there is a family history of this condition.

What are the Symptoms of Hypospadias?

The symptoms of hypospadias may look a little different for each boy who has the condition. In some, the end of the penis may have some degree of downward slant. In some boys, the appearance of the penis and foreskin may be abnormal. The urine stream can also be abnormal based on the position of the urethra and the opening of the penis.

How Common is Hypospadias?

Hypospadias ranks among one of the most common birth defects, affecting approximately one in every 200 boys.

Is Hypospadias genetic?

Hypospadias occurs during fetal development when, reacting to hormone stimulation, the foreskin and urethra form. There is sometimes a genetic component to this condition. However, the environment is also a factor. The risk for hypospadias may be higher in boys with a family history of the condition. Additionally, the risk is higher for preterm babies, boys born to older mothers, or to mothers who have gestational diabetes. Exposure to pesticides or secondhand smoke can also contribute to the risk of hypospadias.

Is Hypospadias Preventable?

Because the cause of hypospadias is not fully understood, there are currently no recommendations for prevention.

What Happens if Hypospadias Goes Untreated?

Very minor cases of hypospadias may not cause problems as the boy develops. However, even moderate malposition of the opening of the penis can cause issues for a boy when he is learning to urinate in the toilet. Depending on the location of the urethral opening, urine may spray downward or in various directions. As physical development progresses, it is possible that the penis may develop a curve. This curvature can result in sexual dysfunction or infertility during adulthood.

Is Surgery Necessary?

Surgery may be recommended in all but the most minor cases of hypospadias. Repositioning the urethra and straightening the penis, if needed, can prevent problems as the child learns to urinate. Surgical repair is performed by an experienced pediatric urologist, typically after the child is 6 months of age or older. The child receives general anesthesia for this outpatient procedure and may also receive caudal anesthesia that blocks nerve sensations in the lower body. A single surgical procedure during infancy can support the proper development of the penis. In more severe cases of hypospadias, it may take more than one surgery to correct the issue.

How Is Hypospadias Treated?

Surgery is the only treatment available. Your child will not outgrow this condition. These facts should be considered in making your decision:

  • Even if the hypospadias is mild, as many as 15% of boys with hypospadias will have a noticeable downward curvature of the penis that may interfere with the ability to achieve an effective erection in adulthood. In the worst cases fertility may be affected. Also, if the opening is on the underside of the penis, the child may be unable to stand to urinate like other boys. This will affect his social development.
  • The urethral opening may be in the correct position but may be misshapen or enlarged, or a web of skin may be behind the opening. All of these factors can disturb the urinary stream causing some boys to spray to the side or downward. The penis functions but these problems can be embarrassing.
  • Any potential defect must be balanced against the likelihood of successful surgery. But most pediatric urologists will recommend surgery for all but the most minor problems.
  • The exact surgical technique will depend on the degree of hypospadias, and the extent of penile curvature. So you need a pediatric urologist with special skills, training and expertise. The extent of the needed repair can only be determined once the surgery has begun.
  • The vast majority of these surgeries are successful the first time.
  • Surgery carries with it the usual risk of infection, which will be controlled with antibiotics. Bleeding is usually minimal. Good surgical technique will minimize complications.

At What Age Should Surgical Correction Be Done?

Current thinking is that the best time for surgical correction is between 4- 6 months based on physical, psychological and technical considerations. This has been associated with an improved emotional and psychological result. Later age repair has been associated with complications and significant psychological problems.

Surgical Techniques for Hypospadias

There are a variety of surgical approaches. No single technique is appropriate for all repairs. The surgical choice will depend on the degree of severity and location of the hypospadias. Your UT surgeon will discuss the options with you.
