What are Posterior Urethral Valves (PUV)?

Posterior urethral valves (PUV) is a medical condition present at birth where extra flaps of tissue block the urethra. The urethra is the tube that carries urine (pee) out of the body from the bladder. When this tube is blocked, the bladder cannot empty properly. This causes urine to back up, which can damage the bladder and the kidneys over time.

This condition only affects boys and occurs while the baby is still growing in the womb. Because it is a birth defect, it is also known as congenital obstructing posterior urethral membrane (COPUM).

How common are posterior urethral valves in children?

Backward or posterior urethral valves are found in approximately 1 out of every 5,000 to 8,000 boys born each year (about 500 cases annually). It is the most common reason for a blockage in the urinary system of newborn boys.

What are the signs and symptoms of PUV in children?

If a child has posterior urethral valves, you might notice several signs:

  • Weak urine flow: Very little urine comes out, or it only comes out in drips.
  • Urinary Tract Infections (UTIs): Frequent infections in the urinary system.
  • Poor weight gain: Babies may struggle to grow or gain weight at a normal rate.
  • Painful urination: The child appears to be in pain while trying to pee.
  • Difficulty moving: The child may seem sluggish or have trouble with physical activity.
  • Low amniotic fluid: During pregnancy, a doctor may notice low levels of fluid around the baby (oligohydramnios).
  • Swollen kidneys: A fetal ultrasound might show a swollen kidney, a condition called hydronephrosis.

What causes posterior urethral valves to happen?

PUV is caused by a glitch during the early growth of a fetus. Extra tissue grows in the urethra near the bladder, acting like a one-way valve that prevents pee from leaving. This makes the bladder work harder and get smaller. Doctors do not yet know exactly why this extra tissue forms in some babies and not others.

What kind of problems can PUV cause for a child?

If left untreated, PUV can lead to serious complications, including:

  • Vesicoureteral reflux (VUR): This is when urine flows backward from the bladder up toward the kidneys.
  • Urinary blockage: The child is unable to empty their bladder completely.
  • Kidney swelling: Pressure from backed-up urine causes the kidneys to expand.
  • Kidney failure: The kidneys may stop working correctly if the damage is severe.

How does a doctor test a child for posterior urethral valves?

A doctor may first spot signs of PUV during a pregnancy ultrasound. After the baby is born, the doctor may use the following tests to confirm the diagnosis:

  • Kidney Sonogram: An ultrasound to see if the kidneys or bladder look swollen or blocked.
  • Voiding Cystourethrogram (VCUG): A special X-ray that shows how the bladder fills and empties. This helps the doctor see exactly where the blockage is located.
  • Cystoscopy: The doctor uses a small, flexible tube with a camera and light to look directly inside the child’s urinary tract.
  • Blood and Urine Tests: These help the doctor check how well the kidneys are filtering waste.

How do doctors treat posterior urethral valves?

The main treatment for PUV is surgery to remove or destroy the extra tissue blocking the urethra. Doctors often use a small tool to apply heat or electricity to the tissue to clear the path.

Depending on the child's specific needs, a doctor may also suggest:

  • Using a catheter: A small tube inserted to help drain the bladder.
  • Urethral enlargement: Procedures to make the urethra wider.
  • Vesicostomy: A small opening made in the abdomen to allow urine to drain directly from the bladder.
  • Antibiotics: Medicine to prevent or treat infections.
  • Dialysis or Transplant: Required if the child has severe kidney failure.
  • Bladder relaxants: Medicine to help the bladder hold urine and make it easier to go.

In rare cases, a specialized doctor may perform surgery on the baby while they are still inside the womb.

What is the long-term outlook for children with PUV?

Children born with PUV usually require lifelong monitoring. This involves regular blood tests and ultrasounds to ensure the kidneys stay healthy. Even after surgery, some children or adults may experience "leaking" or trouble controlling their urine. Research indicates that about 15% of children with this condition eventually experience kidney failure and may need advanced care.

When should I take my child to see a doctor?

If you notice your child is struggling to urinate, has a weak stream, or shows signs of a urinary infection, you should contact a doctor immediately. Early treatment is the best way to prevent permanent damage to the kidneys.
