Vur Surgery: Procedure, Recovery and Results

VUR surgery is a treatment for vesicoureteral reflux (VUR), a condition in which urine flows backward from the bladder toward one or both kidneys. It may be recommended when reflux is persistent or severe, urinary infections recur, or there is concern about kidney health.

Overview: What Is VUR Surgery?

VUR surgery treats vesicoureteral reflux (VUR), a condition in which urine travels backward from the bladder into the ureters and sometimes the kidneys. Normally, the point where each ureter enters the bladder works like a one-way valve. In VUR, this valve mechanism is not fully effective, allowing bacteria-containing urine to reach the kidneys during urination or when bladder pressure rises.

The goal of VUR surgical treatment is to create or reinforce an effective anti-reflux valve. This can lower the chance of repeated febrile urinary tract infections (UTIs), also called kidney infections, and help protect kidney tissue. Surgery is usually considered after an individualized assessment rather than simply because VUR is found on an imaging test.

VUR is most often diagnosed in childhood, including after a baby or child has a UTI with fever. However, VUR surgery in adults may be considered when reflux persists from childhood or develops in association with urinary tract abnormalities, bladder dysfunction, obstruction or prior surgery. A urologist or pediatric urologist can explain whether observation, medication, bladder care or a procedure is the most appropriate approach.

How Serious Is VUR?

VUR can range from mild to more significant. Lower grades often resolve as a child grows and the bladder-ureter connection matures. Higher-grade reflux is less likely to disappear on its own and may be associated with a greater chance of recurrent febrile UTIs and kidney scarring, especially if infections are not recognized and treated promptly.

The condition is not automatically dangerous, and many people with VUR do well with careful follow-up. The main concern is repeated infection reaching the kidneys. Over time, kidney scarring can affect blood pressure or kidney function in a small group of patients, particularly when reflux is severe or infections are recurrent.

Risk is assessed using several factors, not VUR grade alone. These include the child’s age, infection history, ultrasound findings, kidney growth, bowel and bladder habits, and whether there are structural urinary tract differences. Urinary tract infections should be assessed promptly, particularly when fever, flank pain, vomiting or illness occurs in a young child.

Do Kids Outgrow VUR?

Yes, many children outgrow VUR, particularly low-grade reflux diagnosed at a younger age. As the bladder and urinary tract develop, the tunnel through which the ureter enters the bladder can become longer and better able to prevent backflow. For this reason, monitoring is often a suitable initial strategy for children who are otherwise doing well.

Spontaneous resolution is less likely with high-grade VUR, reflux affecting both sides, certain kidney or urinary tract abnormalities, or ongoing bladder and bowel dysfunction. Constipation, infrequent voiding and holding urine can increase bladder pressure and may contribute to infection risk, so these concerns are often addressed as part of treatment.

Follow-up may include urine tests when symptoms occur, kidney and bladder ultrasound, and occasionally imaging that shows whether reflux remains present. Families should not stop prescribed preventive medication or follow-up visits without consulting the treating clinician, even when a child appears well.

Who May Be a Candidate for VUR Surgery?

VUR surgery may be recommended for a child or adult with recurrent febrile UTIs despite appropriate preventive care, persistent high-grade reflux, new or worsening kidney scarring, reduced kidney growth, or reflux that is unlikely to resolve without intervention. Surgery can also be considered when long-term preventive antibiotics are not tolerated, are not appropriate, or do not adequately reduce infections.

Before recommending a procedure, the care team usually reviews imaging results and the person’s full clinical history. Ultrasound can assess kidney size and swelling, while a voiding cystourethrogram may confirm reflux and determine its grade. Further testing may be needed when there are concerns about kidney function, voiding patterns or anatomical differences.

Addressing bladder and bowel dysfunction is particularly important. A plan may include regular toilet visits, adequate fluid intake, treatment for constipation and guidance on healthy voiding habits. In selected cases, these measures can reduce infections and improve the likelihood that conservative management will succeed.

How VUR Surgery Works: Step by Step

The two main procedures are endoscopic injection and ureteral reimplantation. The best option depends on the grade and pattern of reflux, kidney findings, previous treatment, anatomy and the patient’s overall health. Both are commonly performed under general anesthesia, so the patient is asleep and does not feel pain during the procedure.

In endoscopic treatment, a surgeon passes a narrow camera through the urethra into the bladder. A bulking material is injected beneath the opening of the affected ureter. This supports the valve area and can reduce or stop backflow. The procedure does not require an external incision and is often performed as day surgery. The VUR surgery time for an endoscopic injection is commonly shorter than for open or minimally invasive reconstruction, although timing varies by individual case.

Ureteral reimplantation reconstructs the point where the ureter enters the bladder. The surgeon creates a longer tunnel within the bladder wall so bladder pressure helps close the ureter during urination. It may be performed through an open incision, laparoscopically or with robotic assistance in appropriate settings. Robotic urology surgery may be an option for selected patients, depending on anatomy, age and local surgical expertise.

After either approach, the team monitors urine output, comfort and signs of infection. Some patients need a temporary urinary catheter or stent after reimplantation. The surgeon will explain the expected plan before the procedure, including whether an overnight hospital stay is likely.

VUR Surgery Recovery, Benefits and Risks

VUR surgery recovery depends on the technique used. After endoscopic injection, many patients return home the same day and resume light routine activities within a few days, although temporary burning during urination, urinary urgency or mild blood-tinged urine can occur. After ureteral reimplantation, a short hospital stay may be needed, and recovery commonly takes several weeks as the incision and bladder heal.

The potential benefit of surgery is a meaningful reduction in reflux and febrile UTI risk, with the aim of protecting kidney health. Surgery does not reverse kidney scarring that is already present, but preventing future infections may help reduce the risk of additional injury. Ongoing bladder and bowel care remains important after surgery.

Like all procedures, VUR surgery has possible risks. These include bleeding, infection, pain, anesthesia-related complications, temporary difficulty urinating, continued reflux, ureter narrowing or obstruction, and the need for further treatment. Endoscopic injection may be less invasive but can have a higher chance of persistent or recurrent reflux than reimplantation in some situations.

Families should follow postoperative instructions carefully, including guidance on fluids, activity, pain relief, wound care and medication. The care team should be contacted if there is fever, worsening pain, repeated vomiting, inability to pass urine, significant bleeding, drainage from a wound or concerns about a child’s general condition.

What Is the Success Rate of VUR Surgery?

VUR surgery success rate depends on the type of procedure, reflux grade, urinary tract anatomy, bladder and bowel function, and how success is measured. Ureteral reimplantation has a high overall success rate and is generally considered the most durable surgical option. Endoscopic injection is also effective for many patients, but some may have ongoing reflux or require a repeat injection or another procedure.

It is important to distinguish between imaging success and clinical success. Imaging success means reflux is no longer seen on follow-up testing. Clinical success may mean that a person no longer has febrile UTIs and has stable kidney health, even if minor reflux is still detectable. The treating urologist can discuss expected results for the individual patient rather than relying on one general percentage.

Success also depends on preventing and managing constipation, urine holding and dysfunctional voiding. These issues can continue to increase infection risk even when the anatomical reflux has been corrected. Follow-up plans are tailored to symptoms, kidney findings and the type of surgery performed.

What Are the Long-Term Outcomes of VUR?

Most children and adults with VUR have good long-term outcomes, especially when infections are treated promptly and kidney health is monitored. People whose reflux resolves naturally or after successful treatment often have no major ongoing limitations. Some may need periodic follow-up, particularly if there was high-grade reflux, kidney scarring, reduced kidney function or high blood pressure.

Long-term care can include blood pressure checks, urine testing when symptoms arise, kidney function tests when indicated and ultrasound monitoring. Those with significant kidney scarring may need follow-up into adulthood. During pregnancy, people with a history of VUR, kidney scarring or prior urinary tract reconstruction should tell their obstetric and medical teams, as they may need individualized monitoring.

Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals evaluate and treat urinary reflux and related kidney-urology concerns for international patients. Care may involve pediatric urology, adult urology, nephrology, radiology and other relevant specialists, with treatment decisions based on the individual’s clinical needs.

When to seek medical care: Prompt medical assessment is important for fever with urinary symptoms, flank or back pain, vomiting, pain while urinating, new urinary accidents, cloudy or foul-smelling urine, or a child who appears unusually unwell. Emergency care may be needed for severe illness, dehydration, confusion, inability to urinate or severe pain. Anyone with known VUR should follow the clinician’s plan for testing and treatment when a UTI is suspected.

Frequently asked questions

How long does VUR surgery take?

The length of VUR surgery varies with the technique and the individual anatomy. Endoscopic injection is generally shorter, while ureteral reimplantation takes longer because it involves reconstructing the ureter-bladder connection. The surgical team can provide a more specific estimate before the procedure.

Is VUR surgery painful?

VUR surgery is performed under general anesthesia, so the patient does not feel pain during the procedure. Some discomfort is expected afterward, particularly after ureteral reimplantation, but it is usually managed with an individualized pain-relief plan. Burning with urination or bladder spasms can occur temporarily.

Can VUR come back after surgery?

Persistent or recurrent reflux is possible, particularly after endoscopic injection, although many patients achieve good results. Reimplantation is generally a more durable approach, but no procedure is entirely risk-free. Follow-up testing may be recommended if infections recur or symptoms suggest ongoing reflux.

Will my child need antibiotics after VUR surgery?

Some children continue preventive antibiotics for a period after surgery, while others may not need them. The decision depends on the procedure performed, infection history, imaging results and the clinician’s assessment. Parents should give medicines exactly as prescribed and discuss any side effects with the care team.

Can adults have surgery for vesicoureteral reflux?

Yes. VUR surgery in adults may be considered for persistent reflux associated with recurrent kidney infections, pain, kidney damage or certain urinary tract abnormalities. Evaluation may be more complex because adult reflux can be related to bladder function, obstruction or prior urinary procedures.

What follow-up is needed after VUR surgery?

Follow-up may include a postoperative visit, urine testing if symptoms develop, and kidney or bladder ultrasound when appropriate. Some patients need additional reflux imaging, but this is not necessary in every case. The schedule is based on the surgery type, prior reflux severity, infections and kidney findings.
