Introduction
Vesicoureteral Reflux (VUR) is a condition in which urine flows backward from the bladder into the ureters and sometimes back into the kidneys. Normally, urine travels in only one direction—from the kidneys to the bladder. In VUR, this one-way flow is disrupted, increasing the risk of urinary tract infections (UTIs), kidney damage, and long-term kidney complications.
Grade 5 Vesicoureteral Reflux is the most severe form of VUR. It is associated with significant dilation of the ureters and kidneys, severe reflux of urine, and a higher risk of permanent kidney damage if not treated promptly.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney evaluations, advanced diagnostic testing, personalized treatment plans, and long-term monitoring for patients with severe vesicoureteral reflux. When surgical correction is required, we work closely with experienced pediatric or adult urologists to ensure coordinated care.
What Is Vesicoureteral Reflux (VUR)?
Vesicoureteral reflux occurs when the valve between the bladder and ureter does not close properly, allowing urine to flow backward toward the kidneys.
There are two main types:
Primary VUR
Primary VUR is usually present from birth and results from abnormal development of the valve between the bladder and ureter.
Secondary VUR
Secondary VUR develops because of increased pressure in the bladder due to conditions such as urinary obstruction, bladder dysfunction, or neurological disorders.
What Is Grade 5 Vesicoureteral Reflux?
VUR is classified from Grade 1 to Grade 5 based on imaging findings.
Grade 5 is the most advanced stage and is characterized by:
-
Severe backward flow of urine into the kidneys
-
Marked enlargement of the ureters
-
Significant swelling of the kidneys (hydronephrosis)
-
Twisting or distortion of the ureters
-
Loss of the normal shape of the kidney collecting system
-
Increased risk of kidney scarring and reduced kidney function
Prompt treatment is important to preserve kidney health.
Symptoms of Grade 5 Vesicoureteral Reflux
Some patients may have no obvious symptoms until complications develop.
Common symptoms include:
-
Recurrent urinary tract infections
-
Fever without an obvious cause (especially in children)
-
Pain during urination
-
Frequent urination
-
Blood in the urine
-
Flank or lower back pain
-
Poor growth in children
-
High blood pressure
-
Swelling due to declining kidney function
-
Reduced kidney function in advanced cases
Any recurrent urinary infection should be evaluated carefully.
Causes and Risk Factors
Grade 5 VUR may occur due to:
-
Congenital abnormalities of the urinary tract
-
Family history of VUR
-
Bladder dysfunction
-
Urinary tract obstruction
-
Neurogenic bladder
-
Recurrent urinary tract infections
Children with a family history of VUR may require screening.
Complications of Untreated Grade 5 VUR
Without appropriate treatment, Grade 5 VUR can lead to:
-
Recurrent kidney infections (pyelonephritis)
-
Permanent kidney scarring
-
Chronic kidney disease (CKD)
-
High blood pressure
-
Protein in the urine
-
Reduced kidney growth in children
-
Kidney failure in severe cases
Early diagnosis significantly reduces these risks.
How Is Grade 5 VUR Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a comprehensive kidney assessment.
Medical History and Physical Examination
Your doctor will review:
-
Urinary symptoms
-
Previous urinary tract infections
-
Family history
-
Blood pressure
-
Kidney-related symptoms
-
Growth and development in children
Blood Tests
Important investigations include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Electrolytes
-
Complete Blood Count (CBC)
These tests help assess kidney function.
Urine Tests
Urine analysis helps detect:
-
Infection
-
Blood
-
Protein
-
Kidney damage
Urine culture may be performed when infection is suspected.
Imaging Studies
Several imaging tests help diagnose VUR.
Kidney Ultrasound
Ultrasound evaluates:
-
Kidney size
-
Hydronephrosis
-
Structural
