Introduction
Medullary nephrocalcinosis is a condition in which calcium deposits build up in the inner part of the kidney called the renal medulla. These calcium deposits may affect kidney function and are often associated with conditions that increase calcium levels, alter urine chemistry, or increase the risk of kidney stones.
Although some people with medullary nephrocalcinosis may not have symptoms, others may experience recurrent kidney stones, blood in urine, urinary infections, or changes in kidney function. Early diagnosis and appropriate treatment are important to prevent complications and protect long-term kidney health.
The goal of medullary nephrocalcinosis treatment is not only to manage calcium deposits but also to identify and treat the underlying cause.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney evaluations, advanced diagnostic testing, kidney stone management, metabolic kidney disorder treatment, personalized treatment plans, dialysis guidance, kidney transplant evaluation, and long-term kidney care.
What Is Medullary Nephrocalcinosis?
Medullary nephrocalcinosis occurs when calcium salts accumulate in the kidney tissue, particularly in the renal medulla.
These deposits may develop due to:
-
Increased calcium levels in urine
-
Abnormal mineral metabolism
-
Kidney tubular disorders
-
Hormonal abnormalities
-
Genetic conditions
Medullary nephrocalcinosis is different from ordinary kidney stones, although both conditions may occur together.
Causes of Medullary Nephrocalcinosis
Several conditions can lead to calcium deposition in the kidney.
Hypercalciuria
Hypercalciuria means excessive calcium loss through urine.
It is one of the most common causes of nephrocalcinosis.
Hyperparathyroidism
Overactivity of the parathyroid glands can increase blood calcium levels and promote calcium deposition in kidneys.
Distal Renal Tubular Acidosis (dRTA)
This kidney disorder affects acid balance and can increase the risk of calcium deposits and kidney stones.
Medullary Sponge Kidney
A structural kidney condition where abnormal kidney tubules increase the risk of stones and calcium deposits.
High Calcium Levels in Blood
Conditions causing increased blood calcium may contribute to nephrocalcinosis.
Vitamin D Excess
Excessive vitamin D levels may increase calcium absorption and urinary calcium loss.
Genetic Disorders
Some inherited metabolic conditions may increase the risk of nephrocalcinosis.
Symptoms of Medullary Nephrocalcinosis
Many patients may not have noticeable symptoms.
When symptoms occur, they may include:
-
Recurrent kidney stones
-
Flank pain
-
Blood in urine
-
Painful urination
-
Frequent urinary tract infections
-
Increased urination
-
Excessive thirst
-
Abnormal kidney function tests
Symptoms depend on the underlying cause and severity of calcium deposits.
Complications of Medullary Nephrocalcinosis
Without proper evaluation and management, complications may include:
-
Recurrent kidney stones
-
Urinary obstruction
-
Kidney infections
-
Reduced kidney function
-
Chronic kidney disease in severe cases
Early treatment helps reduce these risks.
How Is Medullary Nephrocalcinosis Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a detailed evaluation.
Medical History and Examination
The doctor reviews:
-
Kidney stone history
-
Urinary symptoms
-
Diet and fluid intake
-
Family history
-
Previous kidney problems
-
Medication and supplement use
Blood Tests
Investigations may include:
-
Serum calcium
-
Phosphorus levels
-
Parathyroid hormone (PTH)
-
Serum creatinine
-
eGFR
-
Electrolytes
-
Vitamin D levels
These tests help identify metabolic causes.
Urine Tests
Urine evaluation may include:
-
Urine calcium levels
-
Urine citrate levels
-
Urine oxalate levels
-
Urine pH
-
24-hour urine stone risk profile
These tests help understand stone-forming tendencies.
Imaging Studies
Imaging helps detect calcium deposits and associated stones.
Common tests include:
-
Kidney ultrasound
-
CT scan
-
X-ray when required
Medullary Nephrocalcinosis Treatment Options
Treatment depends on the underlying cause, severity, and kidney function.
Treating the Underlying Cause
The most important step is identifying and managing the condition causing calcium deposits.
Treatment may include:
-
Managing hormonal disorders
-
Correcting acid-base imbalance
-
Treating kidney tubular disorders
-
Managing metabolic abnormalities
Increasing Fluid Intake
Adequate hydration helps:
-
Dilute urine
-
Reduce crystal formation
-
Lower kidney stone risk
Fluid intake should be personalized according to kidney function and medical advice.
Dietary Changes
A kidney-friendly diet may include:
-
Reducing excessive salt intake
-
Maintaining appropriate calcium intake
-
Avoiding excessive animal protein
-
Managing oxalate intake when required
Diet recommendations depend on urine test results.
Medications
Depending on the cause, your nephrologist may prescribe:
Thiazide Diuretics
May help reduce urinary calcium loss in selected patients.
Potassium Citrate
May be recommended in certain patients to increase urinary citrate and reduce stone formation.
Other Specific Treatments
Treatment may be required for:
-
Hyperparathyroidism
-
Renal tubular acidosis
-
Vitamin D-related abnormalities
Can Medullary Nephrocalcinosis Be Reversed?
In many cases, existing calcium deposits may not completely disappear.
However, treatment can:
-
Prevent further calcium accumulation
-
Reduce kidney stone formation
-
Protect kidney function
-
Manage the underlying condition
Early diagnosis improves long-term outcomes.

Patients with medullary nephrocalcinosis can protect kidney health by:
-
Drinking adequate fluids as advised
-

Frequently Asked Questions (FAQs)
Can medullary nephrocalcinosis be cured?
Existing calcium deposits may not always disappear, but treatment can prevent progression and reduce complications.
Is medullary nephrocalcinosis the same as kidney stones?
No. Nephrocalcinosis involves calcium deposits within kidney tissue, while kidney stones form as crystals within the urinary system. Both conditions can occur together.
Does drinking water help nephrocalcinosis?
Adequate hydration may help reduce urine concentration and lower the risk of kidney stone formation.
Which doctor treats medullary nephrocalcinosis?
A super specialist nephrologist evaluates and treats metabolic kidney disorders, nephrocalcinosis, and kidney stone-related conditions.
