A ureteric stone is a kidney stone that has moved into the ureter—the thin tube that carries urine from the kidneys to the bladder. When a stone blocks the ureter, it causes severe pain, infection, or urinary obstruction. Ureteric stones are a very common urological problem and require timely treatment to relieve pain and prevent kidney damage.

Causes

Stones form when minerals in the urine crystallize. The most common causes include:

• Dehydration

• High salt diet

• Excess intake of oxalate-rich foods

• Family history of kidney stones

• Obesity

• Urinary infections

• Medical conditions like gout

• Excess vitamin D or calcium supplements

Stones may vary in size from small grains to larger ones that block the ureter.

Symptoms

A ureteric stone usually causes sudden, sharp, and intense symptoms:

• Severe pain in the back, side, or lower abdomen

• Pain radiating to the groin or testicles

• Nausea and vomiting

• Burning or difficulty urinating

• Frequent urge to urinate

• Blood in the urine

• Fever or chills (sign of infection — medical emergency)

The pain often comes in waves, known as “renal colic.”

Diagnosis

To confirm the presence and location of a ureteric stone, the doctor may recommend:

• Ultrasound

• X-ray KUB

• Non-contrast CT scan (most accurate test)

• Urine analysis

• Blood tests to check kidney function

These tests help determine the size, location, and severity.

Treatment Options

Treatment depends on the size of the stone and the severity of symptoms.

1. Medical Management (For Small Stones)

Stones less than 5 mm may pass naturally with:

• Pain-relief medications

• Alpha-blockers to relax the ureter

• Hydration and dietary changes

2. Minimally Invasive Procedures

a) Ureteroscopy (URS)

A thin scope is passed through the urine passage to reach the stone. Laser is used to break the stone into small pieces which are removed safely.

b) Laser Lithotripsy

A high-powered laser precisely breaks the stone into fine dust (dusting technique).

c) DJ Stent Placement

A temporary stent is placed inside the ureter to relieve obstruction, reduce pain, and help stone fragments pass easily.

3. ESWL (Shockwave Lithotripsy)

Shockwaves are used to break the stone from outside the body. Effective for selected types of stones.

4. PCNL (Percutaneous Nephrolithotomy)

For very large or impacted stones, a small hole is made in the back to remove the stone directly.

Diet & Prevention

To prevent recurrence:

• Drink 2–3 liters of water daily

• Reduce salt intake

• Avoid excessive tea, coffee, and soft drinks

• Cut down on oxalate-rich foods (spinach, nuts, chocolate)

• Consume a balanced diet with fruits and vegetables

• Maintain a healthy weight

A metabolic evaluation may be recommended for recurrent stone formers.

Conclusion

Ureteric stones can cause severe pain and urinary obstruction, but modern treatments offer quick relief. Minimally invasive techniques like URS and laser lithotripsy provide excellent outcomes with fast recovery. Early diagnosis, hydration, and lifestyle modifications help prevent recurrence and protect kidney health.
