Kidney Stone Symptoms: Diagnosis and Treatment Options

Kidney stones are hard deposits made from minerals and salts that form inside the kidneys. They can vary in size, and while some pass naturally through the urinary tract, others may cause severe pain or require medical treatment.

Recognizing kidney stone symptoms early can help you seek appropriate care and reduce the risk of complications.

What Are the Common Symptoms of Kidney Stones?

Small kidney stones may not cause noticeable symptoms until they move within the kidney or enter the ureter, the tube connecting the kidney to the bladder.

Common symptoms include:

• Severe side or back pain: Pain may occur below the ribs and spread toward the lower abdomen or groin.
• Painful urination: You may experience burning or discomfort while passing urine.
• Blood in the urine: Urine may appear pink, red or brown, although blood may only be detectable through testing.
• Frequent urination: You may feel the need to urinate more often than usual.
• Nausea and vomiting: These may accompany intense pain.
• Cloudy or foul-smelling urine: This may indicate an infection, particularly when accompanied by other symptoms.

Symptoms can vary depending on the stone's size, location and whether it blocks the flow of urine.

When Should You Seek Medical Attention?

Seek urgent medical care if you experience severe pain, fever or chills with suspected kidney stones, difficulty passing urine, or persistent vomiting.

A kidney stone that blocks the urinary tract and causes an infection can become a medical emergency. Do not wait for symptoms to improve on their own in these situations.

Even if the pain subsides, arrange medical evaluation if you suspect a kidney stone, especially if you have blood in your urine or a history of kidney problems.

How Are Kidney Stones Diagnosed?

A doctor may recommend several tests to confirm the presence of a stone and determine its size and location.

1. Urine test: Checks for blood, signs of infection and substances that may contribute to stone formation.

2. Blood tests: Assess kidney function and may identify abnormalities involving calcium or other substances.

3. Ultrasound: Uses sound waves to detect many kidney stones and signs of urinary blockage without radiation.

4. CT scan: A non-contrast CT scan is commonly used when detailed imaging is needed to identify stones and assess their location and size.

The appropriate tests depend on your symptoms, age, pregnancy status and medical history.

What Are the Treatment Options for Kidney Stones?

Treatment depends on the stone's size, location, composition and the presence of complications.

1. Drinking Fluids and Monitoring

Some small stones can pass naturally. Your doctor may recommend adequate fluid intake, pain management and follow-up to confirm that the stone has passed.

Do not force excessive amounts of water, particularly if you are vomiting, have a urinary obstruction or have been advised to restrict fluids.

2. Medication

Doctors may prescribe pain relief and, in selected cases, medicines that help certain ureteral stones pass. Antibiotics are used when a bacterial infection is present.

Medication choice depends on the patient's health, stone characteristics and other medicines being taken.

3. Shock Wave Lithotripsy

This procedure uses focused shock waves to break a stone into smaller fragments that can pass through the urinary tract. It is suitable for selected stones, depending on their size and location.

4. Ureteroscopy

A thin instrument is passed through the urinary tract to locate and remove or break up a stone. A temporary stent may be required in some cases.

5. Percutaneous Nephrolithotomy

For larger or complex kidney stones, a specialist may remove the stone through a small incision in the back. This procedure is generally reserved for stones that are unlikely to be managed effectively with less invasive approaches.

How Can You Help Prevent Kidney Stones?

Prevention depends on the type of stone and your individual risk factors. General measures may include:

• Drink enough fluids throughout the day, unless your doctor has advised otherwise.
• Reduce excessive salt intake.
• Maintain a balanced diet and a healthy body weight.
• Avoid unnecessary high-dose vitamin C supplements.
• Do not eliminate calcium-rich foods without medical advice; normal dietary calcium can help prevent certain stones.
• Follow any dietary or medication recommendations based on your stone analysis and test results.

People who develop recurrent stones may benefit from a stone analysis and a 24-hour urine evaluation to identify specific risk factors.

Which Doctor Treats Kidney Stones?

A urologist specializes in conditions affecting the urinary tract and is often the appropriate specialist for kidney stones, particularly when a procedure may be needed.

A general physician may help with the initial assessment and arrange referrals or investigations. If there are signs of kidney impairment, a nephrologist may also be involved in care.

Frequently Asked Questions

Can kidney stones pass naturally?

Yes. Many small stones pass without surgery, although the likelihood depends on their size and location. Medical follow-up may be needed to confirm that the stone has passed.

Are kidney stones always painful?

No. Some stones cause no symptoms and are discovered during imaging for another reason. Pain may develop if a stone moves or blocks urine flow.

Can kidney stones come back?

Yes. Some people develop stones repeatedly. Identifying the stone type and addressing relevant dietary, metabolic or medical risk factors can help reduce recurrence.

Is blood in the urine always a sign of kidney stones?

No. Blood in the urine can have several causes, including infection and other urinary tract conditions. It should be medically evaluated even if it occurs without pain.
