16320 Deflux Treatment For Vesicoureteral Reflux

Overview

Vesicoureteral reflux (VUR) is a condition where urine flows the wrong way, from the bladder back up toward the kidneys. Normally urine travels one way: from the kidneys, down tubes called ureters, into the bladder, and out of the body. In VUR, the valve-like junction where each ureter enters the bladder does not close well. A bulking injection is a procedure that adds a small amount of gel-like material near that junction to create a fuller, better-sealing bulge. This can help reduce backflow. It is one treatment option, not the only one, and not every child or adult with VUR needs it.

VUR is one of the more common urinary problems in young children. It is often found after a urinary tract infection (UTI) or before birth on an ultrasound. Mild cases are common, and many improve with time.

It mostly affects infants and young children, but it can be found at any age. Some children are diagnosed before birth because of swollen kidneys on ultrasound. Adults can have VUR too, usually because of another bladder or urinary problem, but this is less common.

Symptoms

Common symptoms

• Many people with VUR have no symptoms at all.
• A urinary tract infection may be the first sign: fever, burning or stinging when passing urine, needing to urinate often, wetting accidents, or cloudy or smelly urine.
• Older children and adults may feel pain in the side or lower back.
• Some children have unexplained fever, poor feeding, or vomiting.

Symptoms in children

• Fever without a clear cause, especially in babies.
• Vomiting or poor feeding.
• Irritability or unusual drowsiness.
• Burning or pain when passing urine.
• New wetting after being toilet trained.
• Constipation can make bladder problems worse.

Symptoms in older adults

• Repeated urinary tract infections.
• Pain in the side or lower back.
• High blood pressure if kidney scarring has occurred.
• Bladder emptying problems or bladder pressure from another condition.

Causes

Main causes

• Primary VUR: a child is born with a short or poorly supported tunnel where the ureter enters the bladder, so the valve does not close fully.
• Secondary VUR: backflow happens because pressure in the bladder is high or urine cannot empty well, for example from bladder muscle problems, nerve conditions, or blockage.
• Sometimes VUR runs in families.
• Constipation and holding urine can worsen bladder pressure and symptoms.

Risk factors

• Family history of VUR or kidney problems.
• Swollen kidneys seen on a prenatal ultrasound.
• Repeated urinary tract infections, especially with fever.
• Constipation or bladder habits that raise bladder pressure.
• Conditions affecting the spinal cord or nerves that control the bladder.
• Being a young child with a urinary tract infection.

When to see a doctor

See a doctor urgently if:

• Fever with pain in the side or back.
• Vomiting so the person cannot keep fluids down.
• Blood in the urine.
• Strong pain when passing urine.
• A baby or child who is very sleepy, difficult to wake, or not passing urine.

Book a routine appointment if:

• Your child has repeated urinary tract infections, wetting, or fever with urine changes.
• You have been told your child has VUR and you want to discuss treatment choices.
• You notice poor growth, poor appetite, or high blood pressure.
• You have side or back pain that keeps returning.
• You are planning pregnancy and have a history of kidney problems.

Diagnosis

A healthcare provider starts with the story of symptoms, a physical exam, and urine tests. Imaging is used to see whether urine flows backward and whether the kidneys have been affected. The main test is a voiding cystourethrogram (VCUG), which uses a small tube and X-ray pictures to watch urine flow. Other tests may check kidney shape, scarring, and function.

Tests that may be done

• Urine test to look for infection.
• Ultrasound of the kidneys and bladder.
• VCUG to confirm and grade reflux.
• Nuclear medicine scan to check for kidney scarring.
• Blood tests and blood pressure checks to monitor kidney function.
• Sometimes bladder function tests if emptying problems are suspected.

What to expect at your appointment

Your child may need to lie still for imaging, and a VCUG uses a small tube placed briefly into the bladder. The team will explain ways to keep your child comfortable. Results are often given as a grade from 1 to 5, with higher grades meaning more backflow. Your provider will use the grade, age, infections, and kidney findings to discuss options.

Treatment

Treatment depends on age, the grade of reflux, whether there have been infections, and whether the kidneys show scarring. Many children with mild VUR are watched closely and improve as they grow. Others need steps to prevent urinary infections or a procedure to reduce backflow. A bulking injection is a day-case procedure done with a camera passed through the urine opening. The surgeon injects a gel-like material near the ureter opening to make a small bulge. It does not involve a cut in the abdomen. It can help some people, but it does not work for everyone and may need to be repeated.

Self-care at home

• Follow the follow-up plan your healthcare team gives you.
• Treat constipation with diet, fluids, and toilet routines as advised.
• Encourage regular toilet trips and avoid holding urine for long periods.
• Offer plenty of fluids, especially water.
• Learn the signs of urinary infection and get care promptly.
• Keep all imaging and clinic appointments.

Medical treatments

Doctors may use preventive antibiotics in some children to lower the risk of kidney infections. Bladder and bowel training can help reduce pressure and infections. Blood pressure and kidney function are checked over time. If reflux is severe or infections continue, options include endoscopic bulking injection or surgery to reposition the ureters. The choice is made with your healthcare team.

When is surgery considered?

A procedure may be discussed when there are repeated urinary infections with fever despite other care, kidney scarring or worsening kidney function, high-grade reflux that is not improving, or a structural problem that needs correction. Bulking injection may be an option for some children; open or keyhole surgery may be better for others. Your surgeon will explain the benefits and risks.

Living with this condition

Day to day, the focus is on healthy bladder habits, preventing constipation, and catching infections early. After a bulking injection, most children go home the same day and return to normal activities quickly, but follow your team's advice. Keep a simple record of fevers, urine changes, and wetting so you can share it at check-ups.

Lifestyle tips

• Regular toilet times, especially before bed and school.
• Treat constipation early with fiber, fluids, and advice from your team.
• Avoid holding urine for long periods.
• Good genital hygiene, and wiping front to back for girls.
• Prompt care for urinary tract infections.
• Regular blood pressure checks if kidney scarring is present.

Diet and exercise

No special diet is needed for VUR. A balanced diet with enough fiber and fluids helps prevent constipation, which can worsen bladder problems. Children can take part in normal play and sports. Adults should stay active as able. Ask your provider if you need to limit caffeine or fizzy drinks because they irritate the bladder for some people.

Mental health and emotional wellbeing

VUR and repeated hospital tests can be worrying for children and parents. It is normal to feel anxious about procedures or infections. Talk with your team about what to expect, and let children ask questions in simple words. Support from family, school, and patient groups can help. If you or your child feels very distressed, unsafe, or has thoughts of self-harm, contact your local emergency number or crisis service right away.

Prevention

Primary VUR is present at birth and cannot be prevented. You can lower the chance of complications by treating urinary infections quickly, preventing constipation, following up on bladder problems, and keeping recommended appointments. Secondary VUR may be reduced by managing the condition that raises bladder pressure.

Vaccines

There is no vaccine for VUR. Keep up with routine vaccinations, and ask your provider about any extra vaccines recommended for kidney or urinary conditions.

Screening programmes

There is no routine screening for VUR in the general population. Prenatal ultrasound may show swollen kidneys, and children with urinary infections and fever may need imaging. If VUR runs in your family, ask your provider whether siblings should be checked.

Complications

If left untreated

• Repeated urinary tract infections.
• Kidney infection.
• Kidney scarring.
• High blood pressure.
• Reduced kidney function in severe cases.
• Problems during pregnancy for some adults with kidney scarring.

Long-term outlook

The outlook is good for most people, especially with mild reflux and regular follow-up. Many children improve as they grow, and treatments can lower the risk of infection and kidney damage. A bulking injection helps some people but not all. Your healthcare team can help you choose the right plan and adjust it over time.
