Vesicoureteral reflux (VUR) is a condition in which urine flows backward from the bladder toward one or both ureters and, in some cases, toward the kidneys.

Normally, urine travels in one direction: from the kidneys through the ureters into the bladder. A valve-like mechanism at the junction of the ureter and bladder helps prevent backward flow.

When this mechanism does not work properly, urine can move back toward the upper urinary tract.

VUR is more commonly diagnosed in children, but adults can also have reflux. In adulthood, it may be discovered because of recurrent urinary tract infections, kidney infections, abnormal kidney imaging, scarring or previously undiagnosed reflux.

Treatment is not identical for every adult. The appropriate approach depends on whether reflux is causing infections, kidney damage, obstruction or other complications.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized assessment of kidney disease, recurrent urinary infections and kidney-function problems associated with urinary tract disorders.

Why Can VUR Occur in Adults?

Adult vesicoureteral reflux can have different causes.

Some adults may have had reflux since childhood that was never diagnosed or continued into adulthood.

Other cases may develop or become clinically significant because of problems affecting the bladder or urinary tract.

Possible contributors include:

• Previous urinary tract abnormalities

• Recurrent urinary infections

• Bladder dysfunction

• Urinary obstruction

• Neurogenic bladder

• Previous urinary tract procedures

• Abnormal bladder pressure

• Structural abnormalities of the ureterovesical junction

Determining whether VUR is primary or secondary can influence the treatment strategy.

What Symptoms Can Vesicoureteral Reflux Cause in Adults?

VUR itself may not always produce obvious symptoms.

When complications occur, an adult may experience:

• Recurrent urinary tract infections

• Repeated kidney infections

• Burning during urination

• Frequent urination

• Urinary urgency

• Fever or chills during infection

• Flank or back pain

• Blood in urine

• Abnormal kidney-function tests

• High blood pressure in some patients with kidney damage

A person can also have kidney scarring from reflux without having prominent urinary symptoms.

For this reason, recurrent or unexplained urinary infections deserve appropriate evaluation.

Can Adults Have VUR Without Symptoms?

Yes.

Some adults may have VUR that is discovered incidentally during evaluation for another urinary or kidney problem.

The presence of reflux does not automatically mean that surgery is required.

Doctors consider whether the reflux is associated with:

• Recurrent infections

• Kidney scarring

• Declining kidney function

• Significant urinary abnormalities

• Bladder dysfunction

• Persistent complications despite treatment

The treatment decision is therefore based on the clinical consequences of reflux rather than the imaging finding alone.

How Is Vesicoureteral Reflux Diagnosed in Adults?

The diagnostic approach depends on the symptoms and suspected cause.

Urine Examination

Urinalysis can help identify:

• White blood cells

• Blood

• Protein

• Other abnormalities

Urine Culture

When infection is suspected, urine culture can help identify the organism and guide antibiotic treatment.

Kidney Function Tests

Blood tests may include:

• Serum creatinine

• eGFR

• Electrolytes

• Other tests based on the patient's condition

These help determine whether kidney function has been affected.

Ultrasound

Ultrasound may be used to evaluate:

• Kidney size

• Kidney structure

• Hydronephrosis

• Urinary tract abnormalities

• Other causes of recurrent urinary problems

Voiding Cystourethrogram

A voiding cystourethrogram (VCUG) uses contrast imaging during urination to demonstrate backward movement of urine from the bladder toward the ureters.

Whether VCUG is appropriate for an adult depends on the clinical circumstances.

Additional Imaging

Depending on the situation, CT, MRI, nuclear medicine studies or other investigations may be considered.

A specialist may use several tests together rather than relying on one scan.

What Is the Main Goal of VUR Treatment in Adults?

Treatment is generally aimed at preventing complications rather than simply eliminating the reflux seen on an imaging test.

Important goals include:

• Preventing recurrent urinary infections

• Protecting kidney tissue

• Reducing the risk of additional kidney scarring

• Treating urinary obstruction or bladder dysfunction

• Preserving kidney function

• Managing associated high blood pressure

• Addressing the underlying cause of secondary reflux

The best treatment may therefore differ substantially between two adults with the same reflux grade.

Does Every Adult With VUR Need Surgery?

No.

Some adults can be managed without corrective surgery, particularly when reflux is mild, infections are absent or infrequent, kidney function is stable and there is no evidence of progressive kidney damage.

Management may include:

• Observation

• Periodic kidney-function monitoring

• Prompt treatment of urinary infections

• Investigation of recurrent infections

• Management of bladder dysfunction

• Treatment of urinary obstruction

• Blood-pressure monitoring

Surgery may be considered when clinically significant problems continue despite appropriate medical management.

Antibiotics in Adult Vesicoureteral Reflux

If a urinary infection occurs, appropriate antibiotic treatment may be required.

The choice of antibiotic should be based on factors such as:

• Urine culture

• Local bacterial resistance

• Allergies

• Kidney function

• Severity of infection

• Other medicines being taken

Some adults with recurrent infections may require a prevention strategy, but long-term antibiotic use is not automatically appropriate for everyone with VUR.

A nephrologist or urologist should determine whether preventive antibiotics are justified.

Can VUR Cause Kidney Infections?

Yes.

When urine flows backward toward the kidneys, bacteria from the lower urinary tract can potentially reach the upper urinary tract more easily.

Repeated kidney infections can contribute to kidney inflammation and scarring in susceptible patients.

Symptoms such as fever, chills, flank pain, nausea or vomiting together with urinary symptoms may indicate a kidney infection and require timely medical assessment.

Can Vesicoureteral Reflux Damage the Kidneys?

It can.

The greatest concern is often reflux-associated kidney scarring, particularly when reflux occurs alongside recurrent upper urinary tract infections.

Long-standing kidney damage may contribute to:

• Protein in urine

• High blood pressure

• Reduced kidney function

• Chronic kidney disease

However, not every adult with VUR develops kidney damage.

Early recognition of recurrent infections and appropriate evaluation can help reduce preventable complications.

VUR and Reflux Nephropathy

Reflux nephropathy refers to kidney damage associated with vesicoureteral reflux and renal scarring.

Some adults diagnosed with reflux nephropathy may have developed kidney scars years earlier, sometimes during childhood.

Management focuses on protecting the remaining kidney function.

Depending on the individual situation, this may involve:

• Blood-pressure control

• Monitoring eGFR

• Checking urine albumin or protein

• Managing recurrent infections

• Avoiding unnecessary kidney-harming medicines

• Treating other CKD risk factors

If substantial chronic kidney damage has already occurred, eliminating reflux does not necessarily restore scarred kidney tissue.

When Is Surgery Considered for Adult VUR?

Surgical correction may be discussed when reflux is clinically significant.

Possible reasons include:

• Recurrent kidney infections despite appropriate treatment

• Repeated infections associated with reflux

• Progressive kidney damage

• Significant reflux with complications

• Failure of conservative management

• Structural abnormalities requiring correction

The decision should be individualized after evaluating kidney function, bladder function, infection history and urinary anatomy.

Ureteral Reimplantation for VUR

One established surgical approach is ureteral reimplantation.

The procedure changes the way the ureter enters the bladder to improve the anti-reflux mechanism.

Depending on the patient's anatomy and the surgical approach, the operation may be performed through open, laparoscopic or robotic techniques.

The suitability of a particular technique depends on the individual case and the expertise of the treating surgical team.

Endoscopic Treatment for Vesicoureteral Reflux

In selected patients, an endoscopic procedure may be considered.

A bulking substance can be injected near the ureteral opening to improve the anti-reflux mechanism.

Whether this approach is appropriate in an adult depends on:

• Reflux severity

• Anatomy

• Previous treatment

• Infection history

• Kidney condition

• Local expertise

Not every adult with VUR is a candidate for endoscopic treatment.

How Is Treatment Chosen Between Monitoring and Surgery?

A specialist may consider several questions:

Are urinary infections recurring?

Repeated infections despite appropriate treatment may make active intervention more important.

Is there kidney scarring?

Existing renal damage changes the long-term risk assessment.

Is kidney function stable?

A declining eGFR requires careful investigation.

Is there a bladder or urinary obstruction problem?

Treating an underlying bladder or outlet problem may be essential in secondary VUR.

Has previous medical management worked?

The response to infection treatment and other measures helps guide future decisions.

Can VUR in Adults Be Cured?

In some patients, corrective treatment can eliminate or substantially reduce clinically significant reflux.

However, treatment cannot automatically reverse kidney scarring that has already developed.

The word “cure” therefore needs to be used carefully.

The practical goals are often to prevent further infections, protect kidney function and correct an underlying structural or functional problem when possible.

VUR and Pregnancy

Adults with a history of VUR or reflux-related kidney damage may require individualized medical care during pregnancy.

Pregnancy can change urinary tract physiology and may increase the importance of monitoring urinary infections and blood pressure.

Women with known kidney scarring, reduced kidney function or significant hypertension should discuss pregnancy planning with their healthcare team.

A nephrologist and obstetric specialist may need to coordinate care depending on the severity of kidney disease.

Can VUR Cause High Blood Pressure?

Kidney scarring associated with reflux can be associated with hypertension.

For adults with reflux nephropathy, periodic blood-pressure monitoring is therefore important.

If hypertension develops, treatment should consider kidney function, urine protein and other cardiovascular risk factors.

What Follow-Up Is Needed After VUR Treatment?

Follow-up depends on the severity of reflux and the patient's kidney condition.

Monitoring may include:

• Blood pressure

• Serum creatinine

• eGFR

• Urine protein or albumin

• Urinalysis

• Assessment for recurrent urinary infections

• Kidney imaging when clinically indicated

Patients who have undergone corrective surgery may also require procedure-specific follow-up.

When Should an Adult With VUR Seek Urgent Care?

Seek prompt medical attention if symptoms suggest a serious urinary infection or obstruction, particularly:

• High fever

• Chills

• Severe flank pain

• Persistent vomiting

• Very little or no urine

• Confusion

• Severe weakness

• Rapid deterioration in health

An infected obstructed urinary tract can become a medical emergency and may require urgent drainage in addition to antimicrobial treatment.

Frequently Asked Questions

What is the best vesicoureteral reflux treatment in adults?

There is no single treatment that is best for every adult. Observation, infection management, treatment of bladder or urinary problems, endoscopic correction or ureteral surgery may be considered depending on the cause and complications.

Can adults outgrow vesicoureteral reflux?

The spontaneous improvement seen in many children is less relevant once a person reaches adulthood. Adult treatment decisions generally focus on current reflux severity, infections, kidney damage and the underlying urinary anatomy.

Can VUR cause recurrent UTIs in adults?

Yes. Reflux can contribute to recurrent urinary infections, particularly when urine travels backward toward the upper urinary tract.

Can vesicoureteral reflux damage the kidneys?

Persistent or clinically significant reflux, especially when associated with recurrent kidney infections, can contribute to renal scarring and chronic kidney problems.

Is surgery always necessary for adult VUR?

No. Some adults can be monitored and managed medically. Surgery is considered when reflux causes significant or recurrent complications or when conservative treatment is unsuccessful.

Can VUR be treated without surgery?

In selected adults, management may involve monitoring, prompt infection treatment, addressing bladder dysfunction or obstruction and controlling kidney-related risk factors. The appropriate approach depends on the individual case.

Which doctor treats vesicoureteral reflux in adults?

A nephrologist evaluates kidney function and reflux-related kidney disease, while a urologist commonly manages structural urinary conditions and corrective procedures. Some patients benefit from coordinated nephrology and urology care.

Conclusion

Vesicoureteral reflux treatment in adults is determined by more than the presence of backward urine flow on an imaging test. The severity of reflux, frequency of urinary infections, kidney scarring, kidney function, bladder function and underlying urinary abnormalities all influence management.

Some adults can be followed with monitoring and appropriate treatment of infections or associated conditions. Others may benefit from endoscopic correction or ureteral reimplantation when clinically significant reflux continues to cause complications.

The main objective is to reduce recurrent infections, protect functioning kidney tissue and prevent further kidney damage.

If you have recurrent urinary infections, unexplained kidney scarring, abnormal kidney-function tests or known vesicoureteral reflux, specialist evaluation can help determine the most appropriate management strategy.
