Urinary calculi are hard deposits that develop when certain substances in urine become concentrated and form crystals. They can develop anywhere within the urinary system, including the kidneys, ureters and bladder.

Depending on their location, they may be called:

• Kidney stones

• Ureteral stones

• Bladder stones

• Urinary tract stones

Some calculi remain small and pass through the urinary tract without treatment. Others become large, obstruct urine flow, cause repeated pain or contribute to urinary infection.

Therefore, urinary calculi treatment is not the same for every patient. The appropriate approach depends on the stone's size, location, composition, symptoms, obstruction, infection status and kidney function.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation of kidney function and urinary stone-related kidney problems.

Where Can Urinary Calculi Develop?

The urinary system includes the kidneys, ureters, bladder and urethra.

A calculus may form or become lodged at different points.

Kidney

Kidney stones may remain inside the collecting system for some time without causing symptoms.

Ureter

When a stone moves from the kidney into the ureter, it can obstruct urine flow and produce renal colic.

Bladder

Bladder stones can develop when urine does not empty completely or when certain urinary conditions promote stone formation.

Urethra

Less commonly, a stone can become lodged in the urethra and interfere with urine flow.

The location of the calculus is an important factor when selecting treatment.

What Symptoms Can Urinary Calculi Cause?

Not every urinary calculus causes symptoms.

When symptoms occur, they may include:

• Sharp pain in the side or back

• Pain spreading toward the abdomen or groin

• Blood in the urine

• Burning during urination

• Frequent urination

• Urinary urgency

• Nausea or vomiting

• Difficulty passing urine

• Cloudy or foul-smelling urine

• Reduced urine output

A stone causing obstruction may produce significant symptoms, while another stone may be discovered incidentally during imaging.

What Determines the Right Urinary Calculi Treatment?

Doctors consider several factors before choosing treatment.

Stone Size

Smaller stones have a greater chance of spontaneous passage than larger stones.

Stone Location

A stone in the kidney may be managed differently from one lodged in the ureter or bladder.

Stone Composition

Different types of stones respond differently to medical treatment.

Urinary Obstruction

A blocked urinary tract may require active treatment rather than observation.

Infection

An infected obstructed urinary system can become a serious medical emergency.

Kidney Function

Creatinine, eGFR and other findings may influence treatment decisions.

Symptoms

Persistent pain, recurrent bleeding, vomiting or urinary symptoms may influence whether active stone removal is recommended.

How Are Urinary Calculi Diagnosed?

A proper diagnosis helps determine whether observation, medication or a procedure is appropriate.

Urine Examination

Urinalysis may identify:

• Blood

• White blood cells

• Crystals

• Protein

• Other abnormalities

A urine culture may be performed if infection is suspected.

Blood Tests

Depending on the situation, testing may include:

• Serum creatinine

• eGFR

• Electrolytes

• Blood count

• Calcium

• Other metabolic measurements

Ultrasound

Ultrasound can help identify many urinary stones and may reveal swelling of the urinary collecting system caused by obstruction.

CT Scan

Non-contrast CT can provide detailed information about:

• Stone size

• Stone location

• Number of stones

• Stone density

• Urinary obstruction

The appropriate imaging method depends on the patient's clinical situation.

Can Urinary Calculi Be Treated Without Surgery?

Some stones can be managed without an operation.

The possibility depends mainly on the stone's size, location and clinical circumstances.

Conservative management may involve:

• Observation

• Appropriate fluid intake

• Pain management

• Medical treatment in selected patients

• Follow-up imaging

Some ureteral stones may pass naturally.

However, a large stone, persistent obstruction, uncontrolled pain, infection or deteriorating kidney function may require active stone removal.

Medicines Used in Urinary Calculi Treatment

Medicines do not dissolve most types of urinary stones.

Depending on the situation, doctors may prescribe medicines to:

• Control pain

• Reduce nausea

• Facilitate passage of selected ureteral stones

• Prevent recurrent stones

• Dissolve certain stone types

Medicines for Stone Passage

Selected patients with appropriate ureteral stones may be offered medicines that relax the ureter and facilitate passage.

These medicines are not suitable for every stone or every patient.

Medical Dissolution of Uric Acid Stones

Certain uric acid stones can sometimes be dissolved through medically supervised urine alkalinization.

Treatment may involve an alkalinizing medicine such as potassium citrate when appropriate.

Calcium-based stones generally cannot be dissolved in this way.

Patients should not take stone-dissolving medicines without knowing the stone type and receiving medical advice.

When Is Urinary Calculi Removal Necessary?

Active treatment may be considered when a calculus causes:

• Persistent or recurrent pain

• Significant urinary obstruction

• Recurrent infection

• Reduced kidney function

• Increasing stone size

• Low likelihood of spontaneous passage

• Persistent stone despite observation

• Other complications

The decision is individualized after reviewing imaging and clinical findings.

ESWL for Urinary Calculi

Extracorporeal shock wave lithotripsy (ESWL) uses externally generated shock waves to fragment selected urinary stones.

It may be suitable for certain stones depending on:

• Size

• Location

• Stone density

• Anatomy

• Body habitus

• Degree of obstruction

The fragmented material may subsequently pass through the urinary tract.

Larger or harder stones may not be ideal for ESWL and can sometimes require multiple treatment sessions.

Ureteroscopy and Laser Treatment

Ureteroscopy is an endoscopic technique used to reach stones through the natural urinary passage.

A small instrument is guided through the urinary tract until the calculus is reached.

A laser can then fragment the stone into smaller pieces.

Depending on the location and stone burden, fragments may be removed using a basket or allowed to pass naturally.

This approach can be used for selected kidney and ureteral stones.

RIRS for Kidney Stones

Retrograde intrarenal surgery (RIRS) is a form of flexible ureteroscopy used to access stones inside the kidney.

A flexible scope is advanced into the kidney, where the stone can be fragmented using laser energy.

RIRS may be considered for selected renal stones based on:

• Stone size

• Location

• Anatomy

• Stone density

• Previous treatment

• Patient factors

Some patients may require more than one procedure when the stone burden is substantial.

PCNL for Larger Urinary Stones

Percutaneous nephrolithotomy (PCNL) is commonly considered for larger or complex kidney stone burdens.

A small tract is created through the skin into the kidney, allowing specialized instruments to reach and fragment or remove the stone.

PCNL can be particularly useful when the stone burden is too large or complex for simpler treatments.

The procedure is not automatically required for every large stone; the treatment plan depends on imaging and individual circumstances.

Bladder Stone Treatment

Bladder calculi may require a different treatment approach from kidney or ureteral stones.

Treatment can involve endoscopic removal or fragmentation of the bladder stone.

Importantly, doctors may also investigate why the bladder stone developed.

Incomplete bladder emptying, urinary obstruction, foreign bodies and certain urinary conditions can contribute to bladder stone formation.

Treating the underlying problem can reduce recurrence.

What Happens If a Stone Blocks Urine Flow?

A urinary calculus can obstruct urine drainage from the kidney.

Prolonged obstruction may cause hydronephrosis and potentially impair kidney function.

The management depends on the severity and cause of the obstruction.

In some circumstances, urine drainage may need to be restored using:

• A ureteral stent

• A nephrostomy tube

• Another appropriate procedure

Definitive stone removal may then be performed after the immediate problem has been stabilized.

Urinary Calculi With Infection: When Is It Urgent?

An obstructed urinary tract combined with infection can be a medical emergency.

Concerning symptoms include:

• Fever

• Chills

• Severe flank pain

• Vomiting

• Confusion

• Markedly reduced urine output

• Rapidly worsening illness

In this situation, antibiotics and urgent drainage may be required. Definitive stone treatment may be performed after the infection is appropriately controlled.

Do not delay medical care while trying home remedies.

Can Urinary Calculi Damage the Kidneys?

Small, uncomplicated stones do not necessarily cause permanent kidney damage.

However, complications can occur when a stone produces:

• Prolonged obstruction

• Repeated urinary infections

• Significant inflammation

• Recurrent kidney injury

Patients with recurrent stones or abnormal kidney-function tests may benefit from specialist evaluation.

How Can Urinary Calculi Be Prevented?

Removing a stone does not necessarily eliminate the factors that caused it.

Prevention should therefore be considered after treatment, especially in people with recurrent stones.

Maintain Appropriate Fluid Intake

Adequate fluid intake can help dilute urine and reduce the concentration of stone-forming substances.

The target should be individualized, particularly in people with kidney failure, heart disease or fluid restrictions.

Reduce Excess Sodium

High dietary sodium can increase urinary calcium excretion in some people and may contribute to calcium stone risk.

Reducing excessive salt intake can be part of a prevention plan.

Do Not Follow Extreme Diets

Dietary recommendations should depend on the stone composition and metabolic evaluation.

For example, unnecessary restriction of normal dietary calcium is not appropriate for everyone with calcium stones.

Stone Analysis

If a stone is recovered, laboratory analysis can help identify its composition.

Metabolic Evaluation

People with recurrent or high-risk stones may be evaluated using blood tests and, when appropriate, 24-hour urine testing.

This can identify factors that increase the risk of future stone formation.

Can Lemon Water Cure Urinary Calculi?

Citrus beverages can provide citrate, which may have a role in preventing certain types of kidney stones.

However, lemon water should not be considered a treatment that reliably removes an existing large urinary calculus.

A large or obstructing stone should be evaluated medically rather than relying on home remedies.

Should You Drink Excess Water to Flush Out a Stone?

No.

Maintaining appropriate hydration is important, but drinking excessive quantities of water does not guarantee that a stone will pass.

If the urinary tract is obstructed, forcing fluids can increase discomfort and does not remove the physical blockage.

Fluid intake should be based on individual medical advice.

Recovery After Urinary Calculi Treatment

Recovery depends on the treatment performed.

After procedures, some patients may experience:

• Mild blood in urine

• Temporary urinary burning

• Increased urinary frequency

• Flank discomfort

• Passage of small stone fragments

A temporary ureteral stent may be placed in selected cases.

Follow-up imaging may be recommended to confirm whether residual stones remain.

Patients should follow their treating specialist's instructions regarding medicines, activity, fluid intake and follow-up.

How Can Recurrent Urinary Calculi Be Managed Long Term?

People with repeated stones may need a more detailed prevention strategy.

Long-term management can include:

• Identifying the stone type

• Reviewing dietary factors

• Checking relevant metabolic abnormalities

• Monitoring kidney function

• Maintaining appropriate hydration

• Controlling blood pressure

• Treating urinary infections

• Taking prescribed preventive medicines

• Attending follow-up imaging

A prevention plan should be tailored to the individual's stone composition and risk factors.

When Should You Consult a Kidney Specialist?

A nephrologist can help evaluate kidney function and medical conditions associated with recurrent or complicated stones.

Specialist assessment may be appropriate when there is:

• Recurrent urinary calculi

• Reduced eGFR

• Elevated creatinine

• Protein in urine

• Recurrent urinary infection

• Urinary obstruction

• Kidney-function deterioration

• Difficult-to-control blood pressure

• Other kidney abnormalities

When a stone requires an endoscopic or surgical removal procedure, a urologist may also be involved.

Frequently Asked Questions

What is the treatment for urinary calculi?

Treatment depends on the stone's size, location, composition and symptoms. Options may include observation, medicines, ESWL, ureteroscopy with laser lithotripsy, RIRS or PCNL.

Can urinary calculi pass naturally?

Some smaller stones can pass without a procedure. Larger stones have a lower likelihood of spontaneous passage, and obstruction, infection or persistent symptoms may require active treatment.

Which medicine dissolves urinary stones?

Most stones cannot be dissolved with medicine. Selected uric acid stones may be treated with medically supervised urine alkalinization.

Is laser treatment used for urinary calculi?

Yes. Ureteroscopy with laser lithotripsy can fragment selected kidney and ureteral stones. RIRS uses flexible ureteroscopy to treat stones located within the kidney.

Is ESWL suitable for every urinary stone?

No. ESWL suitability depends on stone size, location, density, anatomy and other patient factors.

When is PCNL used?

PCNL is commonly considered for larger or complex kidney stone burdens. The decision depends on imaging and individual clinical factors.

Can urinary calculi cause kidney damage?

A stone can potentially affect kidney function if it causes prolonged obstruction, recurrent infection or other complications.

Can urinary calculi be prevented after treatment?

Recurrence can sometimes be reduced through appropriate fluid intake, dietary measures, stone analysis, metabolic evaluation and prescribed preventive treatment.

Conclusion

Urinary calculi treatment depends on much more than the presence of a stone. Its size, location, composition, symptoms, urinary obstruction, infection status and kidney function all influence the appropriate management strategy.

Some smaller stones may pass naturally with observation and appropriate medical care. Others require active removal through ESWL, ureteroscopy with laser treatment, RIRS or PCNL.

A blocked urinary tract accompanied by infection requires particularly prompt medical attention because it can become a serious complication.

After a stone has been treated, identifying why it formed can also be valuable. Stone analysis, appropriate metabolic evaluation, dietary adjustments and individualized preventive care may help reduce recurrence.
