Posterior Urethral Valves that (PUV) – Causes & Treatment

What are Posterior Urethral Valves?

Posterior Urethral Valves that are PUV are causing blockage membranes that develop in the urethra. That is a tube that drains urine from the bladder and closes to the bladder. The valve can block the outflow of urine through the urethra. When this occurs, the bladder, ureters, and kidneys become progressively expanded normally. It can lead to damage.

The degree that the urine is blocked will find the fact of the urinary tract problems.

The Causes of Posterior Urethral Valves

The PUV is thought to develop in the early stages of fetal development. The abnormality affects only male infants. It occurs in about 1 in 8,000 births. This disorder is usually occurred by chance. However, in some of the cases, it has been seen in twins and siblings. Suggesting a Genetic component.

The Signs and Symptoms of Posterior Urethral Valves

The PUV occurs in varying degrees from mild to severe. Because of the increased use of prenatal imaging. Posterior Urethral Valves may be identified before any symptoms are present. If any dilation or hydronephrosis is identified. The baby will be monitored throughout the pregnancy and after the birth. Once the baby is born, more imaging studies will confirm the diagnosis.

Many children, who are diagnosed later also may have the following signs or symptoms that require treatment:

The Urinary tract infection

The Weak urine stream

The Difficulty with urination

The Urinary frequency

The New onset of Urinary the loss of bladder control

The Testing and Diagnosis

We use Voiding Cystourethrogram that is VCUG. To diagnose the Posterior Urethral Valves. During this test, a catheter that is the tube is placed through the child’s urethra into the bladder. The tube will be used to slowly fill the bladder with a solution called Contrast. But the bladder is being filled, a special machine that is Fluoroscopy.

It is used to take pictures. The Radiologist looks to see if any of the contrast goes back up into the kidneys. This study is used to diagnose the Vesicoureteral Reflux that is VUR. Additional pictures are taken while the child is urinating. The radiologist will look at the urethra. But urine is passing to identify the blockage that is PUV.

We will also look at the child’s kidneys and also bladder in relation to the kidneys bladder ultrasound that is RBUS. This procedure uses sound waves to shape the kidneys and bladder. It will enable us to see the degree of Hydronephrosis. And also the shape of the bladder.

We may also order blood tests to check how well the kidneys are functioning.

The Treatment for Posterior Urethral Valves

The Surgical treatment

The Treatment for Posterior Urethral Valves depends on the severity of the condition. The child’s age, bladder, and kidney status. The surgical target is to preserve the kidney and bladder function.

Valve the surgical removal of body tissue:

Once PUV is identified. They need to be surgical marked. During the valve ablation, the urologist will insert a Cystoscope. It is a small device with a light and a camera lens at the end. He will use this instrument to make the action in the valves. So they collapse and no longer obstruct the urethra.


In a situation where the baby is too small. To undergo a valve ablation. When a severe obstruction is noted, a Vesicostomy may be recommended. A vesicostomy provides an opening to the bladder. So that the urine drains freely from the lower abdominal opening. During the surgery, a small part of the bladder wall is turned inside out. It joins to the abdomen.

It looks like a small slit, which is surrounded by pink tissue. A vesicostomy is a temporary option that can be closed in the future. After the successful bladder drainage. Either by the valve ablation or vesicostomy. We will continue to monitor the child’s condition throughout his childhood and adolescence.

We will need to assess the kidney function. To watch for kidney growth and see how the child does through toilet training. Some children need ultrasounds every year. But others may benefit from the medications and additional surgeries. Our team will work with one and the family to make a plan based on the child’s condition.

Visit the Center for Fetal Diagnosis and Treatment that is CFDT. To learn more about the lower urinary tract obstruction that is LUTO. Watch our LUTO video on how our Urology and CFDT teams collaborate. To provide an exact diagnosis before the birth. The expert assessment and treatment after the birth.

The Long-term care

As the child nears adulthood. Our dedicated Urology Transitional Care Program is here to help one. The child prepares for the process from pediatric to adult medical care. For many patients with difficult urologic conditions like Posterior Urethral Valves. It is especially important that the care they receive remains effective and more efficient. Learn more about how this relation between CHOP and the Hospital of the University of Pennsylvania can support one through this process.

So, this is the important information on the topic of Posterior Urethral Valves that is PUV. Here I have mentioned the Meaning, Causes, Signs, and symptoms, The treatment in surgical its medical name in full description.
