Kidney stones can develop silently for months before causing symptoms. Some stones remain small and unnoticed, while others move into the urinary tract and cause sudden, severe pain. Recognizing the signs of kidney stones early can help prevent complications such as urinary obstruction, kidney infection, and kidney damage.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist and transplant physician, provides expert diagnosis, medical management, minimally invasive stone treatment, and long term prevention strategies for kidney stone disease.

What are kidney stones

Kidney stones are hard mineral deposits that form inside the kidneys. They may remain in the kidney or move into the ureter, the tube that carries urine from the kidney to the bladder.

The severity of symptoms depends on:

  • Stone size

  • Stone location

  • Degree of urinary obstruction

  • Presence of infection

  • Individual pain sensitivity

Early signs of kidney stones

One of the earliest signs may be intermittent discomfort in the side of the back, especially when the stone begins to move.

Early symptoms can include:

  • Mild flank discomfort

  • Occasional back pain

  • Increased urinary frequency

  • Burning during urination

  • Blood in the urine

  • Nausea

  • Restlessness

Small stones may cause minimal symptoms initially.

Severe flank pain

The most common sign of a kidney stone is sudden severe pain in the flank, the area between the ribs and the hip.

This pain may:

  • Begin suddenly

  • Come in waves

  • Become extremely intense

  • Shift from the back toward the lower abdomen

  • Radiate to the groin

Patients often find it difficult to remain still during an episode.

Blood in the urine

A kidney stone may irritate the urinary tract, causing:

  • Pink urine

  • Red urine

  • Brown urine

  • Microscopic blood detected on urine testing

Blood in the urine should always be medically evaluated.

Pain during urination

As the stone moves lower in the urinary tract, patients may experience:

  • Burning urination

  • Sharp pain during urination

  • Difficulty passing urine

  • Urinary urgency

  • Frequent urination

These symptoms may resemble a urinary tract infection.

Nausea and vomiting

Severe kidney stone pain commonly causes:

  • Nausea

  • Vomiting

  • Sweating

  • Restlessness

These symptoms occur because kidney pain can strongly affect the nervous system.

Reduced urine output

A stone causing significant obstruction may lead to:

  • Difficulty passing urine

  • Reduced urine volume

  • Intermittent urine flow

  • A feeling of incomplete emptying

Obstruction requires prompt medical evaluation.

Fever with kidney stone symptoms

Fever is not a typical symptom of an uncomplicated kidney stone.

If a kidney stone is accompanied by:

  • Fever

  • Chills

  • Severe weakness

  • Persistent vomiting

A kidney infection may be present, and urgent treatment is necessary.

Signs of kidney stones in women

Women may experience:

  • Flank pain

  • Lower abdominal pain

  • Frequent urination

  • Burning urination

  • Blood in the urine

  • Nausea

  • Groin pain

Kidney stones can sometimes be mistaken for gynecological conditions or urinary infections.

Signs of kidney stones in men

Men often report:

  • Severe flank pain

  • Pain radiating to the groin

  • Testicular discomfort

  • Blood in the urine

  • Urinary urgency

  • Nausea and vomiting

The location of pain may change as the stone moves.

When kidney stone symptoms become an emergency

Seek immediate medical attention if you have:

  • Fever

  • Chills

  • Severe uncontrolled pain

  • Persistent vomiting

  • Inability to pass urine

  • Heavy blood in the urine

  • Reduced urine output

  • Pain with a known solitary kidney

These symptoms may indicate obstruction or infection.

How kidney stones are diagnosed

A nephrologist may recommend:

  • Urine examination

  • Blood tests

  • Kidney function tests

  • Ultrasound

  • CT scan when indicated

  • Stone analysis

  • Metabolic evaluation for recurrent stones

Accurate diagnosis helps determine the most appropriate treatment.

Treatment for kidney stones

Treatment depends on stone size, location, and symptoms.

Options may include:

  • Hydration

  • Medicines

  • Medical expulsive therapy

  • ESWL

  • Ureteroscopy

  • PCNL for large stones

Many small stones can be managed without surgery under medical supervision.

Preventing future kidney stones

Patients with one kidney stone have a higher risk of recurrence.

Prevention strategies include:

  • Drinking adequate water

  • Reducing excessive salt intake

  • Maintaining a healthy weight

  • Managing diabetes

  • Treating recurrent urinary infections

  • Following stone specific dietary recommendations

  • Regular kidney monitoring

Metabolic evaluation can help identify the underlying cause of recurrent stones.
