Kidney stone treatment has evolved considerably, giving doctors several minimally invasive ways to remove stones while taking the stone's size, location, composition, anatomy and the patient's overall health into account.

The phrase “latest kidney stone treatment” does not refer to one new procedure that is suitable for everyone. Modern stone care is increasingly based on personalized selection of the procedure rather than using the same treatment for every stone.

Depending on the situation, current treatment options can include:

• Observation for selected small stones

• Medical treatment to support spontaneous passage in appropriate patients

• Shock wave lithotripsy (SWL or ESWL)

• Ureteroscopy with laser lithotripsy

• Flexible ureteroscopy and RIRS

• Percutaneous nephrolithotomy (PCNL)

• Staged or combined procedures for complex stone burden

The European Association of Urology continues to recommend choosing stone treatment according to factors such as stone size, location, composition, anatomy and patient-specific considerations.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides kidney-focused evaluation and helps patients understand the appropriate treatment pathway for kidney stones and associated kidney-function problems.

How Has Kidney Stone Treatment Become More Targeted?

Modern stone management is not simply about breaking a stone into smaller pieces.

Doctors also consider:

• Whether the stone is causing obstruction

• Whether infection is present

• Stone size and number

• Exact location within the kidney or ureter

• Stone density and composition

• Kidney anatomy

• Previous stone procedures

• Kidney function

• Other medical conditions

• Patient preferences and treatment goals

Imaging, particularly appropriate CT-based assessment when indicated, can provide important information before an intervention is selected.

This approach can help avoid unnecessary procedures and improve the likelihood of effective stone clearance.

Can Small Kidney Stones Still Be Treated Without Surgery?

Yes.

Not every kidney stone requires an operation.

Some smaller stones, particularly those with a reasonable chance of spontaneous passage and without complications, can be managed initially with observation, pain management and selected medical treatment.

The decision depends on:

• Stone diameter

• Location

• Symptoms

• Degree of obstruction

• Infection status

• Kidney function

• Likelihood of spontaneous passage

A stone that is small but causing persistent obstruction or infection may require active treatment despite its size.

Latest Laser Treatment for Kidney Stones

Laser lithotripsy is one of the important technologies used in modern endoscopic stone treatment.

During ureteroscopy, a thin endoscope is introduced through the natural urinary tract to reach the stone.

A laser is then used to fragment the stone into smaller pieces.

Depending on the procedure and stone characteristics, fragments may be:

• Extracted with a basket

• Broken into very small pieces

• Allowed to pass naturally when appropriate

Laser treatment can be used for selected stones in the ureter and kidney.

The technology and surgical technique may vary between procedures and centers, so patients should discuss the specific approach with the treating specialist.

What Is RIRS and Why Is It Used?

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

A flexible instrument is passed through the urinary tract and into the kidney. The stone can then be fragmented using laser energy and, when appropriate, fragments can be removed.

RIRS may be considered for selected renal stones where an endoscopic approach is appropriate.

It can be particularly useful when the stone's location makes other approaches less suitable.

However, RIRS is not automatically the preferred treatment for every large stone.

Stone burden, anatomy, density and expected clearance all influence the decision.

Is PCNL Still Used in Modern Kidney Stone Treatment?

Yes.

Despite advances in flexible endoscopy and laser technology, percutaneous nephrolithotomy (PCNL) remains an important treatment for larger or complex kidney stones.

In PCNL, a small access tract is created through the skin into the kidney. Instruments are introduced through this tract to fragment and remove the stone.

For large renal stone burdens, PCNL can provide substantial stone clearance.

The EAU guideline continues to recommend PCNL as a major treatment option for large renal calculi, particularly stones greater than 2 cm.

The exact procedure may be modified according to the patient's anatomy and stone characteristics.

What About Shock Wave Lithotripsy?

Shock wave lithotripsy (SWL or ESWL) remains an established non-invasive treatment option for selected kidney and ureteral stones.

Instead of inserting an instrument into the urinary tract, externally generated shock waves are focused on the stone.

The stone is fragmented into smaller pieces that may subsequently pass through the urinary tract.

Its effectiveness depends on factors including:

• Stone size

• Stone location

• Stone density

• Body habitus

• Kidney anatomy

• Stone composition

• Presence of obstruction

SWL may therefore be appropriate for some patients but less suitable for others.

Which Modern Treatment Is Suitable for a Large Kidney Stone?

Large stones require more careful planning.

Depending on the stone burden, possible approaches include:

• PCNL

• Flexible ureteroscopy or RIRS

• SWL in selected situations

• Staged procedures

• Combined approaches in complex cases

For renal stones above approximately 2 cm, PCNL is generally an important first-line consideration because larger stone burdens can be difficult to clear efficiently with other methods.

However, individual anatomy and clinical circumstances can change the treatment decision.

What Is the Latest Treatment for Stones in the Ureter?

Ureteral stones are managed according to their size, location and likelihood of passing naturally.

Selected smaller stones can sometimes be observed.

If active removal becomes necessary, modern options may include:

Ureteroscopy

A thin endoscope is passed through the urinary tract to reach the stone.

Laser Lithotripsy

Laser energy fragments the stone during ureteroscopy.

Shock Wave Lithotripsy

External shock waves can fragment selected ureteral stones.

The choice depends on the stone's location, size, obstruction, symptoms and patient factors.

Can Kidney Stones Be Removed in One Procedure?

Sometimes, but not always.

The likelihood of complete clearance depends on:

• Total stone burden

• Number of stones

• Stone density

• Location

• Kidney anatomy

• Procedure selected

• Previous interventions

Very large or complex stones may require staged treatment.

Trying to achieve complete clearance in a single procedure is not always the safest approach.

What Happens If a Kidney Stone Causes Infection?

A stone associated with an infected and obstructed urinary system requires urgent medical attention.

In this situation, definitive stone removal may not be the first step.

The immediate priority may be to restore urine drainage using:

• A ureteral stent

• A nephrostomy tube

Antibiotic treatment and supportive care are also important.

Once the infection has been appropriately controlled, definitive stone treatment can be planned.

An infected obstructed kidney can deteriorate rapidly and should not be managed by waiting at home.

Is There a New Medicine That Can Remove Kidney Stones?

There is no universal medicine that dissolves or removes all kidney stones.

Medication may have different roles depending on the situation.

For example, selected medicines may:

• Control stone-related pain

• Facilitate passage of certain ureteral stones

• Help prevent recurrent stones

• Treat specific metabolic abnormalities

• Dissolve selected uric acid stones under medical supervision

Most common calcium-containing stones cannot simply be dissolved with a tablet.

Therefore, patients should not rely on products advertised as universal “stone breakers” or kidney cleansers.

Does Drinking More Water Remove Kidney Stones?

Adequate fluid intake is important for kidney stone prevention and may support passage of some small stones.

However, forcing large amounts of water does not guarantee that a stone will pass.

If a stone is obstructing urine flow, excessive fluid intake can increase discomfort and does not remove the physical blockage.

Patients with kidney disease, heart disease, urinary obstruction or fluid restrictions should follow individualized fluid advice.

How Is the Right Treatment Selected?

Before recommending a procedure, the treating team may assess:

Stone Size

A 4 mm stone and a 25 mm stone cannot be approached in the same way.

Stone Location

A lower-pole kidney stone may have different treatment considerations from a ureteral stone.

Stone Density

CT findings can help estimate how easily certain stones may respond to SWL.

Number of Stones

Multiple stones can alter the treatment strategy.

Kidney Anatomy

The shape and drainage pattern of the kidney can affect access and stone clearance.

Infection

Active urinary infection needs appropriate management before elective stone removal.

Kidney Function

Creatinine and eGFR may be particularly important when obstruction or bilateral stones are present.

Patient Factors

Age, medical conditions, medications, previous procedures and individual preferences can influence treatment selection.

What Tests Are Usually Done Before Stone Treatment?

Depending on the clinical situation, evaluation may include:

• Ultrasound

• Non-contrast CT

• Urinalysis

• Urine culture when infection is suspected

• Serum creatinine

• eGFR

• Electrolytes

• Complete blood count

• Stone analysis when a stone is retrieved

Imaging provides important information about stone size, location and obstruction.

Laboratory testing helps identify infection and assess kidney function before treatment.

Is Modern Kidney Stone Surgery Minimally Invasive?

Many current stone procedures are minimally invasive.

Examples include:

• Flexible ureteroscopy

• RIRS

• Laser lithotripsy

• PCNL

• SWL

However, “minimally invasive” does not mean “risk-free.”

Possible complications depend on the procedure and can include:

• Bleeding

• Infection

• Residual stone fragments

• Ureteral injury

• Temporary urinary symptoms

• Stent discomfort

• Need for another procedure

The treating specialist should explain procedure-specific risks before treatment.

What Is a Ureteral Stent and Why Might It Be Used?

A ureteral stent is a thin tube placed between the kidney and bladder to maintain urine drainage.

It may be used:

• After ureteroscopy

• When the ureter is swollen

• When stone fragments need to pass

• To relieve obstruction

• During staged stone treatment

A stent is generally temporary and requires planned removal or exchange.

Patients may experience urinary frequency, urgency, discomfort or mild blood in urine while the stent is present.

What Happens After Modern Kidney Stone Treatment?

Follow-up is important even after the stone has been removed.

Depending on the procedure and stone type, follow-up may involve:

• Imaging to confirm clearance

• Kidney-function testing

• Stone analysis

• Metabolic evaluation

• Dietary advice

• Assessment for recurrent stones

Removing the existing stone does not necessarily remove the reason why the stone formed.

How Can Future Kidney Stones Be Prevented?

Prevention should be tailored to the stone type and individual risk factors.

Common measures may include:

• Maintaining appropriate fluid intake

• Limiting excessive dietary sodium

• Following a balanced diet

• Maintaining an appropriate body weight

• Treating metabolic abnormalities

• Taking prescribed preventive medicines

• Completing metabolic evaluation when recommended

• Analyzing the stone when possible

People with recurrent stones may benefit from a more detailed metabolic assessment, including urine testing over an appropriate period.

When Should a Kidney Stone Be Treated Urgently?

Seek prompt medical attention if a suspected or known kidney stone is associated with:

• Fever or chills

• Severe or uncontrolled pain

• Persistent vomiting

• Very little or no urine

• Severe weakness

• Confusion

• Rapidly worsening symptoms

• Known urinary obstruction with infection

An obstructed and infected urinary system can become dangerous and requires urgent treatment.

What Is the Role of a Kidney Specialist?

A nephrologist evaluates kidney function and medical kidney conditions associated with stones, including:

• Acute kidney injury

• Chronic kidney disease

• Electrolyte abnormalities

• Proteinuria

• Reduced kidney function caused by obstruction

Stone-removal procedures such as ureteroscopy, RIRS and PCNL are generally performed by urological specialists, while nephrologists may be involved when kidney function or medical kidney disease requires specialist management.

A coordinated approach can be useful for patients with complex kidney disease and recurrent or complicated stones.

Frequently Asked Questions

What is the latest treatment for kidney stones?

Modern kidney stone treatment includes flexible ureteroscopy, laser lithotripsy, RIRS, SWL and PCNL, along with observation or medical treatment for selected patients. The appropriate option depends on stone size, location, anatomy, obstruction and other factors.

Is laser treatment the latest kidney stone treatment?

Laser lithotripsy is an established modern technique rather than a single new treatment that replaces all other procedures. It is commonly used during ureteroscopy and RIRS for selected stones.

Is RIRS better than PCNL for kidney stones?

Neither procedure is universally suitable for every patient. PCNL is an important option for large renal stones, while RIRS may be appropriate for selected stones based on size, location and anatomy.

Can ESWL still be used for kidney stones?

Yes. SWL or ESWL remains an option for selected kidney and ureteral stones. Its success depends on stone characteristics and patient anatomy.

Can a kidney stone be removed without surgery?

Some small stones can pass naturally with appropriate observation and medical management. Larger, persistent, obstructing or complicated stones may require an active removal procedure.

How do I know which kidney stone treatment I need?

Imaging and clinical evaluation help determine the appropriate treatment. Stone size, location, density, number, anatomy, infection status, symptoms and kidney function are important factors.

Is modern kidney stone treatment safe?

Modern procedures are generally well established, but every intervention has potential risks. The risks and benefits depend on the specific procedure and individual health condition.

Can kidney stones come back after removal?

Yes. Stone removal treats the existing stone but does not automatically eliminate the factors that caused stone formation. Preventive evaluation can help reduce recurrence risk.

Conclusion

The latest kidney stone treatment is not one single procedure. Modern stone care offers several approaches, including flexible ureteroscopy, laser lithotripsy, RIRS, SWL and PCNL, as well as observation and medical management for selected patients.

The most appropriate treatment depends on the stone's size, location, number, density, anatomy, obstruction, infection status and the patient's kidney function and overall health.

For large or complex renal stones, PCNL remains an important treatment option, while laser-based endoscopic procedures can provide effective treatment for selected kidney and ureteral stones.

If a stone causes infection and urinary obstruction, urgent drainage and medical treatment may be required before definitive stone removal.
