Doctor explaining kidney stone symptoms and early signs to a patient using a kidney model

Kidney stone symptoms usually include sudden, severe pain in the side or back, blood in the urine, nausea, and a frequent urge to urinate. These signs appear when a hard mineral deposit blocks or irritates the urinary tract. Recognising them early helps you seek treatment before complications arise. This article explains what kidney stones are, the key early warning signs, other causes, complications, diagnosis, and the treatment options available at Lux Hospitals. Read on to learn when your discomfort may signal a stone and when to consult a specialist promptly.

What Are Kidney Stones?

Kidney stones are hard deposits of minerals and salts that form inside the kidneys. They develop when urine becomes concentrated, allowing crystals to clump together.

Stones vary in size, from tiny grains to larger masses. Common types include:

  • Calcium oxalate stones (most common)
  • Uric acid stones
  • Struvite (infection-related) stones
  • Cystine stones (inherited)

1. Severe Pain in the Side and Back

Intense pain below the ribs, on one side of the back, is the hallmark of kidney stones. This is called renal colic and often comes in waves.

The pain may shift as the stone moves. You may notice it:

  • Starts suddenly and intensely
  • Radiates to the lower abdomen and groin
  • Comes and goes in waves
  • Changes as the stone moves
  • Fluctuates in intensity

2. Blood in the Urine

Blood in the urine, known as hematuria, is a common early sign. It happens when a stone scratches the urinary tract lining.

The colour change may be subtle or obvious. Urine may appear:

  • Pink or reddish
  • Brown or tea-coloured
  • Cloudy with visible blood
  • Normal but positive on tests

3. Painful and Frequent Urination

As a stone reaches the lower urinary tract, urination often becomes uncomfortable. You may feel a burning sensation while passing urine.

This can mimic a urinary infection. Watch for these signs:

  • Burning during urination
  • Frequent, urgent need to urinate
  • Passing small amounts often
  • Feeling of incomplete emptying

4. Nausea and Vomiting

Kidney stones can trigger nausea and vomiting through shared nerve connections with the digestive tract. Severe pain often worsens these feelings.

Dehydration from vomiting can make stones worse. Common experiences include:

  • Persistent nausea with pain
  • Vomiting during pain episodes
  • Loss of appetite
  • Feeling generally unwell

Persistent nausea with back pain? Consult the urology team at Lux Hospitals.

5. Cloudy or Foul-Smelling Urine

Cloudy or bad-smelling urine may signal a stone combined with infection. This warrants prompt medical attention.

Changes in urine appearance often accompany other symptoms. You may notice:

  • Cloudy or murky urine
  • Strong, unpleasant odour
  • Darker colour than usual
  • Sediment or particles

6. Fever and Chills

Fever and chills alongside stone symptoms suggest a serious infection. This is a medical emergency requiring immediate care.

Do not delay treatment if these appear. Warning signs include:

  • Fever above 38°C
  • Shaking chills
  • Rapid worsening of pain
  • Confusion or weakness

Fever with kidney stone pain needs urgent care—visit Lux Hospitals immediately.

Other Causes and Risk Factors

Several factors raise your risk of forming kidney stones. Diet, hydration, and family history all play a role.

Understanding these helps with prevention. Common risk factors include:

  • Low fluid intake and dehydration
  • High-salt or high-protein diets
  • Family history of stones
  • Obesity and certain medications
  • Digestive conditions like IBD

Possible Complications

Untreated kidney stones can lead to serious problems. Larger stones may block urine flow and damage the kidney.

Early treatment prevents most complications. Risks of delay include:

  • Blocked urine flow (obstruction)
  • Recurrent urinary infections
  • Kidney damage or scarring
  • Severe, worsening pain
  • Sepsis in rare cases

Diagnosis and Treatment at Lux Hospitals

Doctors use imaging and urine tests to confirm kidney stones and plan treatment. The approach depends on stone size and location.

Common diagnostic and treatment options include:

  • CT scan or ultrasound imaging
  • Urine and blood testing
  • Increased fluids for small stones
  • Lithotripsy — non-invasive, for smaller stones
  • Ureteroscopy for stone removal
  • Surgery for large or complex stones

Frequently Asked Questions

What is usually the first sign of a kidney stone?

The first sign is often sudden, sharp pain in the side or back below the ribs. This renal colic may come in waves and radiate toward the lower abdomen and groin as the stone moves.

Can you have a kidney stone without pain?

Yes. Small stones may stay in the kidney and cause no symptoms, sometimes found during unrelated scans. Pain typically begins only when a stone moves into the ureter and blocks urine flow.

How long does it take to pass a kidney stone?

Small stones may pass within days to a few weeks with plenty of fluids. Larger stones can take longer or require medical treatment. Consult a doctor if pain persists beyond a few weeks.

When should I see a doctor for kidney stone symptoms?

Seek care if you have severe pain, blood in the urine, fever, chills, vomiting, or difficulty urinating. Fever with pain may signal infection and needs immediate medical attention.

Does drinking water help pass kidney stones?

Yes. Staying well hydrated helps flush small stones and prevents new ones from forming. Aim for pale, clear urine, but follow your doctor's advice, especially if you have kidney concerns.
