Featured Snippet Answer
Kidney stones are hard mineral deposits that form inside the kidneys when urine becomes concentrated. Common symptoms include severe side or back pain, painful urination, blood in urine, nausea, and frequent urination. Treatment depends on stone size and may include medicines, ESWL, ureteroscopy, or minimally invasive surgery.
Introduction
Kidney stones are one of the most common urinary conditions affecting people across India. From sudden severe pain in the side or back to difficulty passing urine, kidney stones can significantly affect daily life when they move through the urinary tract.
Although small kidney stones may pass naturally, larger stones can cause blockage, infection, and complications if left untreated. Early diagnosis by a qualified urologist and appropriate kidney stone treatment can help relieve symptoms and prevent recurrence.
This guide covers everything you need to know about kidney stone symptoms, causes, risk factors, diagnosis, treatment options, and prevention tips, reviewed by our consultant urologists at Supreme Hospitals, Chennai.
What Are Kidney Stones?
Kidney stones are hard deposits formed inside the kidneys when certain minerals and salts in urine become concentrated and form crystals.
Normally, urine contains substances that prevent crystal formation. However, factors such as dehydration, dietary habits, and certain medical conditions can disturb this balance and allow stones to develop.
Kidney stones can vary in size and may occur anywhere in the urinary system, including:
- Kidneys
- Ureters (tubes connecting kidneys to bladder)
- Bladder
Common types of kidney stones include:
Calcium Stones
The most common type, usually formed when calcium combines with oxalate or phosphate in urine.
Uric Acid Stones
These occur when uric acid levels become high, often linked with dehydration, high-protein diets, or metabolic conditions.
Struvite Stones
Usually associated with urinary tract infections and may grow quickly.
Cystine Stones
Rare stones caused by an inherited condition affecting cystine levels in urine.
Symptoms of Kidney Stones
Kidney stone symptoms vary depending on the size and location of the stone. Some small stones may not cause symptoms, while others can cause severe discomfort.
Severe Side or Back Pain
One of the most common symptoms is sudden, intense pain in the side, lower back, or below the ribs.
The pain may:
- Come and go in waves
- Move toward the lower abdomen or groin
- Become worse as the stone moves
Painful Urination
A stone passing through the urinary tract can cause burning or discomfort while urinating.
Blood in Urine
Kidney stones may irritate the urinary lining and cause urine to appear:
- Pink
- Red
- Brown
Frequent Urination
Some people may experience an increased urge to urinate, especially when the stone moves closer to the bladder.
Nausea and Vomiting
Severe kidney stone pain may trigger nausea and vomiting.
Fever and Chills
Fever with urinary symptoms may indicate an infection and requires urgent medical attention.

Causes and Risk Factors of Kidney Stones
Kidney stones develop due to changes in urine composition. Several factors can increase the risk.
Dehydration
Not drinking enough water is one of the leading causes of kidney stones. Concentrated urine allows minerals to form crystals more easily.
Dietary Factors
Certain dietary habits may increase risk, including:
- High salt intake
- Excess animal protein consumption
- Low water intake
- High intake of oxalate-rich foods
Family History
People with a family history of kidney stones may have a greater chance of developing them.
Obesity and Lifestyle Factors
Excess weight, poor dietary habits, and lack of physical activity may contribute to kidney stone formation.
Medical Conditions
Risk may increase with:
- Recurrent urinary infections
- Diabetes
- Metabolic disorders
- Digestive conditions affecting absorption
Who Is More Likely to Develop Kidney Stones?
Kidney stones are more common among people who:
- Drink less water
- Live in hot climates
- Have excessive sweating
- Follow high-salt diets
- Have a previous history of stones
- Have certain medical conditions
In Chennai’s warm and humid climate, dehydration due to sweating can increase the risk of stone formation, making adequate fluid intake especially important.
How Are Kidney Stones Diagnosed?
A urologist diagnoses kidney stones through symptoms, physical examination, and investigations.
Medical Evaluation
The doctor will assess:
- Pain pattern
- Urinary symptoms
- Previous stone history
- Lifestyle factors
Urine Tests
Urine analysis helps detect:
- Blood in urine
- Infection
- Stone-forming substances
Blood Tests
Blood tests evaluate:
- Kidney function
- Calcium and uric acid levels
Imaging Tests
Common imaging methods include:
Ultrasound
Used to identify stones and check for urinary blockage.
CT Scan
Provides detailed information about stone size and location.
X-Ray
May detect certain types of kidney stones.
Treatment Options for Kidney Stones
Kidney stone treatment depends on:
- Stone size
- Stone location
- Symptoms
- Kidney function
Drinking Fluids and Monitoring
Small stones may pass naturally with increased fluid intake and medical supervision.
Medicines
Doctors may prescribe medication to:
- Control pain
- Reduce discomfort
- Help smaller stones pass
Extracorporeal Shock Wave Lithotripsy (ESWL)
ESWL uses sound waves to break kidney stones into smaller fragments that can pass through urine.
Ureteroscopy
A small camera is inserted through the urinary passage to locate, break, or remove the stone.
Surgical Stone Removal
Large or complicated stones may require minimally invasive procedures for safe removal.
Kidney Stone Prevention Tips
Preventing kidney stones involves simple lifestyle changes.
Drink Enough Water
Adequate hydration helps dilute urine and reduces crystal formation.
Reduce Salt Intake
High sodium intake can increase calcium levels in urine and increase stone risk.
Maintain a Balanced Diet
Include:
- Fresh fruits
- Vegetables
- Whole grains
- Healthy calcium sources
Avoid Excess Animal Protein
Moderate protein intake may help reduce the risk of certain stones.
Maintain Healthy Weight
Regular physical activity supports overall kidney health.
When Should You See a Urologist?
Consult a urologist if you experience:
- Severe or persistent side pain
- Blood in urine
- Fever with urinary symptoms
- Difficulty passing urine
- Repeated kidney stones
- Increasing pain despite medication
Early evaluation helps prevent complications and protects kidney function.
