Kidney failure in children occurs when the kidneys are unable to perform their normal functions adequately. The kidneys help remove waste products and excess fluid, maintain the body's salt and mineral balance and contribute to blood-pressure regulation.
Kidney failure can develop suddenly or gradually.
In children, kidney problems may be caused by conditions present from birth, infections, urinary obstruction, inherited disorders, immune-related diseases or severe illnesses that affect kidney function.
The two broad patterns are:
-
Acute kidney injury, where kidney function declines suddenly
-
Chronic kidney disease, where kidney damage or reduced kidney function persists over time
The treatment and possibility of recovery depend greatly on the cause.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist kidney evaluation and can help guide appropriate nephrology care and coordination for children with kidney-function concerns.
Can Children Develop Kidney Failure?
Yes.
Although kidney failure is often associated with adults, children can also develop serious kidney disease.
Kidney problems in children may occur:
-
Before birth or soon after birth
-
During infancy
-
During childhood
-
During adolescence
Some conditions are inherited or congenital, while others develop later.
Early identification is important because untreated kidney problems can affect:
-
Growth
-
Blood pressure
-
Nutrition
-
Bone health
-
School activities
-
Overall development
What Causes Kidney Failure in Children?
The causes of kidney failure in children differ from those commonly seen in adults.
Congenital Kidney and Urinary Tract Abnormalities
Some children are born with abnormalities affecting:
-
Kidney development
-
Kidney size
-
Urine drainage
-
Ureters
-
Bladder function
Severe abnormalities can affect kidney function over time.
Urinary Obstruction
A blockage that interferes with urine flow can place pressure on the kidneys.
Depending on the cause, obstruction may be related to:
-
Structural abnormalities
-
Narrowing in the urinary tract
-
Bladder problems
-
Other congenital conditions
Persistent obstruction can potentially damage the kidneys.
Recurrent Urinary Tract Infections
Repeated urinary infections can require investigation, especially when a child has fever, abnormal imaging or suspected urinary reflux.
Some children may have an underlying urinary abnormality that increases the risk of repeated infections.
Glomerular and Immune-Related Kidney Diseases
Certain conditions can affect the kidney's filtering units.
Possible findings may include:
-
Protein in urine
-
Blood in urine
-
Swelling
-
High blood pressure
-
Reduced kidney function
The diagnosis may require detailed blood and urine testing and, in selected cases, a kidney biopsy.
Inherited Kidney Disorders
Some kidney diseases can run in families.
Inherited disorders may affect kidney structure or function and can gradually reduce kidney function.
A detailed family history can sometimes provide useful information.
Severe Illness and Acute Kidney Injury
A child can develop sudden kidney dysfunction during serious illness.
Possible contributing factors include:
-
Severe dehydration
-
Serious infection
-
Low blood pressure
-
Major surgery
-
Certain medicines
-
Severe systemic illness
Some cases of acute kidney injury can improve significantly after prompt treatment of the underlying cause.
What Are the Early Symptoms of Kidney Failure in Children?
Kidney disease may not always produce obvious symptoms during the early stages.
Possible warning signs can include:
-
Swelling around the eyes
-
Swelling of the feet or legs
-
Changes in urine amount
-
Very frequent urination
-
Difficulty passing urine
-
Blood in urine
-
Foamy urine
-
Dark urine
-
Persistent fatigue
-
Poor appetite
-
Nausea or vomiting
-
Poor growth
-
Difficulty gaining weight
-
High blood pressure
-
Recurrent urinary infections
Children may not always be able to clearly describe symptoms.
Parents and caregivers should pay attention to persistent changes in urine, appetite, energy level and growth.
Can Kidney Failure Cause Swelling in Children?
Yes.
Reduced kidney function or significant protein loss in urine can contribute to fluid retention.
Swelling may be noticed:
-
Around the eyes
-
In the face
-
Around the ankles
-
In the feet
-
In the legs
However, swelling has many possible causes.
A child with persistent or increasing swelling should receive medical evaluation.
Does Kidney Disease Affect a Child's Growth?
Chronic kidney disease can potentially affect normal growth and development.
Factors that may contribute include:
-
Poor appetite
-
Nutritional difficulties
-
Metabolic abnormalities
-
Hormonal changes
-
Anemia
-
Chronic illness
Children with significant kidney disease may require ongoing monitoring of:
-
Height
-
Weight
-
Nutrition
-
Blood pressure
-
Kidney function
Growth and nutritional care can be an important part of long-term kidney management.
How Is Kidney Failure Diagnosed in Children?
Diagnosis involves more than checking one blood test.
A doctor may assess the child's medical history, symptoms, growth and family history.
Blood Tests
Testing may include:
-
Serum creatinine
-
Kidney-function measurements
-
Electrolytes
-
Bicarbonate
-
Blood count
-
Other tests depending on the child's condition
Urine Tests
Urine examination can help identify:
-
Protein
-
Albumin
-
Blood
-
Infection
-
Other abnormalities
Blood Pressure Measurement
High blood pressure can be both a cause and a complication of kidney disease.
Regular monitoring is important.
Ultrasound and Other Imaging
Imaging may help identify:
-
Kidney size
-
Structural abnormalities
-
Urinary obstruction
-
Abnormal urine drainage
-
Other kidney or urinary tract conditions
Specialized Tests
Depending on the suspected disease, additional investigations may be required.
These can include immune-related tests, genetic evaluation or other specialized assessments.
Kidney Biopsy
In selected children, a kidney biopsy may be recommended to determine the specific type of kidney disease.
A biopsy is not required in every case.
The decision depends on the potential benefit of obtaining more detailed information about the kidney condition.
Treatment for Acute Kidney Failure in Children
Acute kidney injury can sometimes be reversible, depending on the cause.
Treatment may involve:
-
Correcting dehydration appropriately
-
Treating severe infection
-
Managing blood pressure
-
Reviewing medicines
-
Relieving urinary obstruction
-
Correcting electrolyte abnormalities
-
Treating the underlying illness
Severe acute kidney injury may sometimes require temporary dialysis.
The need for dialysis is based on the child's complete clinical condition and not simply on one creatinine value.
Treatment for Chronic Kidney Failure in Children
When kidney disease is long-term, treatment focuses on protecting remaining kidney function and managing complications.
Care may include:
-
Blood-pressure management
-
Treatment of protein loss in urine when appropriate
-
Nutritional management
-
Monitoring growth and development
-
Managing anemia
-
Monitoring mineral and bone health
-
Managing electrolyte abnormalities
-
Avoiding unnecessary kidney-harming medicines
-
Regular kidney-function monitoring
The treatment plan should be individualized for the child.
When Is Dialysis Needed for a Child?
Dialysis may be considered when the kidneys are unable to maintain the body's internal balance and serious complications cannot be adequately controlled through medical treatment.
Possible reasons can include:
-
Severe fluid overload
-
Dangerous electrolyte abnormalities
-
Significant metabolic acidosis
-
Severe symptoms related to kidney failure
-
Advanced kidney dysfunction
The decision is made by the treating pediatric kidney team based on the child's overall condition.
Types of Dialysis Used in Children
Depending on the child's age, medical condition and treatment plan, kidney replacement therapy may include different forms of dialysis.
Peritoneal Dialysis
Peritoneal dialysis uses the lining of the abdomen as a filtering membrane.
It may be an appropriate option for selected children.
Hemodialysis
Hemodialysis uses a dialysis machine and specialized filter to remove waste products and excess fluid from the blood.
The choice of dialysis treatment is individualized.
Kidney Transplant for Children
For selected children with advanced kidney failure, a kidney transplant may provide long-term kidney replacement treatment.
A successful transplant can restore significant kidney function.
However, transplantation requires:
-
Careful medical evaluation
-
Donor assessment
-
Surgery
-
Long-term follow-up
-
Medicines to reduce the risk of transplant rejection
The suitability and timing of transplantation depend on the child's medical condition and transplant evaluation.
Can Kidney Failure in Children Be Cured?
The answer depends on the cause.
Some forms of acute kidney injury can improve significantly when the underlying cause is identified and treated promptly.
However, established chronic kidney disease may involve permanent kidney damage.
In such cases, the goals of treatment may include:
-
Slowing further kidney damage
-
Supporting normal growth and development
-
Managing complications
-
Preserving remaining kidney function
-
Planning kidney replacement therapy when necessary
Every child's condition is different.
How Can Parents Protect a Child's Kidney Health?
Parents and caregivers can support kidney health by following the child's individualized treatment plan.
Important steps may include:
-
