Renal calculi is the medical term for kidney stones. These are hard deposits that develop when certain substances in urine become concentrated and form crystals.

Kidney stones can vary considerably in:

• Size

• Shape

• Location

• Composition

• Density

Very small stones may pass naturally without surgery. Larger stones, stones causing obstruction, persistent pain, infection or stones unlikely to pass may require a procedure.

Renal calculi surgery is therefore not one single operation. Several procedures are available, and the appropriate technique depends on the characteristics of the stone and the patient's health.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist evaluation of kidney stone disease and guidance regarding appropriate treatment and kidney care.

When Is Surgery Needed for Kidney Stones?

Not every kidney stone requires surgery.

A procedure may be considered when a stone:

• Is too large to pass naturally

• Causes persistent or severe pain

• Blocks urine flow

• Causes repeated urinary infections

• Causes deterioration in kidney function

• Continues to grow

• Remains in the urinary tract without passing

• Is associated with significant obstruction

• Has a low likelihood of spontaneous passage

The decision should be based on imaging, symptoms and the patient's overall medical condition.

What Tests Are Done Before Renal Calculi Surgery?

Before selecting a stone-removal procedure, doctors may evaluate:

Imaging

Ultrasound or CT imaging can determine:

• Stone size

• Stone location

• Number of stones

• Degree of obstruction

• Kidney anatomy

A CT scan may provide more detailed information in selected patients.

Urine Testing

Urine tests can help identify blood, infection and other abnormalities.

Blood Tests

Testing may include:

• Serum creatinine

• Kidney-function assessment

• Electrolytes

• Blood counts

• Other tests when clinically required

If an infection is present, it generally needs appropriate treatment before elective stone surgery.

Main Types of Renal Calculi Surgery

The procedure selected depends on the stone.

1. Ureteroscopy

Ureteroscopy (URS) involves passing a thin instrument through the natural urinary passage to reach the stone.

The stone may be:

• Removed using a small basket

• Broken into smaller pieces

• Treated with laser energy

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

A temporary ureteric stent may be placed after the procedure in some patients.

2. Laser Lithotripsy

During ureteroscopy, a laser can be used to fragment the stone into smaller pieces.

Laser treatment is useful for appropriately selected stones and allows the surgeon to directly access the stone.

The exact approach depends on stone size, location and anatomy.

3. PCNL

Percutaneous nephrolithotomy (PCNL) is commonly used for larger or complex kidney stones.

A small access tract is created through the skin into the kidney. Specialized instruments are then used to fragment and remove the stone.

PCNL may be considered for:

• Large kidney stones

• Staghorn stones

• Complex stone burdens

• Stones that are unlikely to be cleared effectively by less invasive methods

4. ESWL

Extracorporeal shock wave lithotripsy (ESWL) uses focused shock waves from outside the body to break selected stones into smaller fragments.

The fragments can subsequently pass through the urinary tract.

ESWL may be suitable for certain stones, but its effectiveness varies depending on stone size, location, density and anatomy.

5. Other Specialized Procedures

In complex cases, the treating urologist may recommend an alternative or staged approach.

The goal is to achieve safe and effective stone clearance while minimizing unnecessary procedures.

How Do Doctors Choose the Right Kidney Stone Surgery?

There is no single procedure that is best for every patient.

The choice can depend on:

Stone size: Larger stones may require PCNL or another intervention rather than simple observation.

Stone location: A stone in the kidney may require a different approach from one lodged in the ureter.

Stone density: Very hard stones may respond differently to shock-wave treatment.

Urinary anatomy: Individual anatomical features can affect the success of a particular procedure.

Kidney function: Existing kidney impairment may influence treatment planning.

Infection: An infected obstructed urinary system requires urgent medical management rather than routine elective stone treatment.

Previous procedures: Previous stone surgery can influence subsequent treatment choices.

Is Kidney Stone Surgery Painful?

Pain varies according to the procedure.

ESWL may cause discomfort during or after treatment.

Ureteroscopy and PCNL are generally performed with anesthesia, so pain is controlled during the procedure. Some discomfort can occur during recovery.

The treating team can provide appropriate pain-management medication based on the procedure and patient's health.

Kidney Stone Surgery Recovery

Recovery depends on the procedure performed.

After ESWL

Patients may experience:

• Mild flank discomfort

• Blood in the urine

• Passage of stone fragments

• Temporary urinary symptoms

After Ureteroscopy

Some patients may experience:

• Mild urinary discomfort

• Urinary frequency

• Flank discomfort

• Blood in the urine

A ureteric stent can sometimes cause temporary urinary symptoms.

After PCNL

Because PCNL involves an access tract through the skin, recovery can take longer than some endoscopic procedures.

Patients may need monitoring for:

• Bleeding

• Infection

• Pain

• Residual stones

Your surgeon will provide individualized instructions about activity, medications and follow-up.

How Long Does It Take to Recover From Kidney Stone Surgery?

Recovery time varies significantly.

Factors include:

• Procedure performed

• Stone burden

• Number of stones

• Presence of infection

• Kidney function

• Patient's general health

• Whether a stent was placed

Some patients return to routine activities relatively quickly after minimally invasive treatment, while complex stone procedures may require a longer recovery.

Is a Stent Needed After Kidney Stone Surgery?

A ureteric stent may be placed after some stone procedures.

It is a thin tube that helps maintain urine flow from the kidney to the bladder while the urinary tract heals.

Not every patient requires a stent.

If one is placed, the treating doctor will explain when and how it should be removed.

What Are the Risks of Renal Calculi Surgery?

Modern kidney stone procedures are generally performed with established safety measures, but complications can occur.

Potential complications include:

• Bleeding

• Infection

• Pain

• Residual stone fragments

• Urinary tract injury

• Temporary urinary symptoms

• Need for additional treatment

• Stent-related discomfort

The risk profile depends on the procedure and the patient's medical condition.

What Happens If a Kidney Stone Blocks Urine?

A blocked urinary system can become serious, particularly when it is accompanied by infection.

Symptoms such as:

• Fever

• Chills

• Severe flank pain

• Vomiting

• Difficulty passing urine

may indicate an urgent problem.

An infected obstructed kidney can require urgent drainage, followed by definitive stone treatment after the infection has been appropriately managed.

Can All Kidney Stones Be Removed in One Surgery?

Not necessarily.

Large, multiple or complex stones may require:

• More than one procedure

• Staged treatment

• A combination of techniques

The objective is safe and effective clearance rather than performing an unnecessarily aggressive single procedure.

What Should You Eat After Kidney Stone Surgery?

Dietary advice should be based on the type of stone and individual risk factors.

General kidney-stone prevention measures may include:

• Maintaining appropriate fluid intake

• Avoiding excessive salt

• Following a balanced diet

• Avoiding unnecessary extreme dietary restrictions

• Maintaining a healthy body weight

For recurrent stones, doctors may recommend metabolic evaluation and, when appropriate, stone analysis.

How Can Kidney Stones Be Prevented From Coming Back?

Removing a stone does not necessarily eliminate the reason it formed.

Preventive evaluation may consider:

• Stone composition

• Urine calcium

• Urine oxalate

• Uric acid

• Citrate

• Urine volume

• Dietary factors

• Family history

• Recurrent infections

Depending on the findings, specific dietary changes or medicines may be recommended.

Does Kidney Stone Surgery Damage the Kidney?

The aim of modern stone surgery is to remove the stone while preserving kidney function.

However, every procedure has potential risks.

Leaving a large obstructing stone untreated can itself threaten kidney health. Therefore, the risks of intervention should be weighed against the risks of continued obstruction or recurrent infection.

Frequently Asked Questions

What is renal calculi surgery?

Renal calculi surgery refers to procedures used to remove or fragment kidney stones. Depending on the stone, treatment may involve ESWL, ureteroscopy with laser treatment, PCNL or another specialized approach.

What is the best surgery for kidney stones?

There is no universally best procedure. The choice depends on stone size, location, density, kidney anatomy, symptoms and other medical factors.

Is laser treatment better than ESWL?

Laser ureteroscopy and ESWL have different advantages. Laser treatment allows direct access to the stone, while ESWL breaks selected stones from outside the body. A specialist should determine which approach is appropriate.

When is PCNL recommended?

PCNL is commonly considered for larger or complex kidney stones, including certain staghorn stones or substantial stone burdens.

Can kidney stones be removed without surgery?

Yes. Small stones may sometimes pass naturally with observation and appropriate medical management. The likelihood of passage depends largely on stone size, location and other factors.

Can kidney stones return after surgery?

Yes. Surgery removes the existing stone but does not always eliminate the factors responsible for stone formation. Preventive evaluation can help reduce recurrence risk.

Conclusion

Renal calculi surgery includes several modern procedures designed to remove or fragment kidney stones. ESWL, ureteroscopy with laser treatment and PCNL are among the commonly used approaches, but the right option depends on the individual stone and patient.

Early evaluation is especially important when a stone causes obstruction, infection, persistent pain or changes in kidney function.

A personalized treatment plan can help balance effective stone clearance with preservation of kidney health.
