Introduction
Renal calculi, commonly known as kidney stones, are hard deposits that develop when certain minerals and salts become concentrated in the urine and form crystals. Small stones may sometimes pass naturally, but larger or complicated stones can require a procedure for safe removal.
Choosing the right renal calculi surgical treatment depends on several factors, including the stone's size, location, composition, symptoms, degree of urinary obstruction, infection, and the patient's overall kidney function.
Modern kidney stone treatment includes minimally invasive procedures such as ureteroscopy with laser lithotripsy, Retrograde Intrarenal Surgery (RIRS), Extracorporeal Shock Wave Lithotripsy (ESWL), and Percutaneous Nephrolithotomy (PCNL).
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist, evaluates kidney function, stone-related risks, recurrent stone causes, and associated medical conditions. When a procedure is required, appropriate urology specialists can be involved for surgical stone removal.
What Are Renal Calculi?
Renal calculi are stones that form within the kidneys or urinary tract.
They may contain different substances, including:
-
Calcium oxalate
-
Calcium phosphate
-
Uric acid
-
Struvite
-
Cystine
Some stones remain in the kidney without causing symptoms, while others move into the ureter and may cause severe pain or urinary obstruction.
When Is Surgical Treatment Needed for Renal Calculi?
Not every kidney stone requires surgery.
A procedure may be recommended when a stone:
-
Is unlikely to pass naturally
-
Causes persistent or severe pain
-
Blocks urine flow
-
Causes hydronephrosis
-
Leads to recurrent urinary infections
-
Causes bleeding or significant urinary symptoms
-
Increases in size
-
Is associated with declining kidney function
-
Is located in a position where spontaneous passage is unlikely
-
Remains despite appropriate observation or medical treatment
The decision is individualized after reviewing imaging, symptoms, kidney function, and other clinical factors.
Factors That Determine the Choice of Stone Procedure
The most suitable procedure depends on:
Stone Size
Larger stones are generally less likely to pass without intervention.
Stone Location
A stone in the kidney may be managed differently from one located in the ureter.
Number of Stones
Multiple stones may require a different treatment strategy from a single small stone.
Urinary Obstruction
Blocked urine flow can increase the risk of kidney damage and may require timely intervention.
Infection
A blocked infected urinary system can become a medical emergency and may require urgent drainage before definitive stone treatment.
Kidney Function
Patients with reduced kidney function require careful treatment planning.
Stone Composition
Certain stone types have specific medical prevention strategies, while most common calcium stones cannot simply be dissolved with medication.
Main Renal Calculi Surgical Treatment Options
1. Ureteroscopy with Laser Lithotripsy
Ureteroscopy (URS) is a minimally invasive procedure commonly used for ureteral and selected kidney stones.
A thin scope is passed through the natural urinary passage into the urinary tract. The stone can then be fragmented using a laser, and fragments may be removed with specialized instruments.
Advantages
-
No external surgical incision
-
Can treat many ureteral stones
-
Laser can fragment stones into smaller pieces
-
Useful when ESWL is unsuitable or unsuccessful
A temporary ureteral stent may sometimes be placed after the procedure.
2. Retrograde Intrarenal Surgery (RIRS)
RIRS is a minimally invasive technique used to treat stones located inside the kidney.
A flexible ureteroscope is guided through the urinary tract into the kidney. A laser may then be used to fragment the stone, allowing the fragments to be removed or pass naturally.
RIRS may be considered for selected renal stones based on their size, location, anatomy, and other patient-specific factors.
3. Extracorporeal Shock Wave Lithotripsy (ESWL)
ESWL uses externally generated shock waves to break a kidney stone into smaller fragments.
The fragments may then pass through the urinary tract naturally.
ESWL may be appropriate for selected stones depending on:
-
Stone size
-
Stone location
-
Stone composition
-
Body anatomy
-
Degree of obstruction
ESWL is not suitable for every patient or every stone.
4. Percutaneous Nephrolithotomy (PCNL)
PCNL is commonly used for larger or complex kidney stones.
A small access tract is created through the skin into the kidney. Instruments are introduced through this tract to break and remove the stone.
PCNL may be considered for:
-
Large kidney stones
-
Staghorn calculi
-
Multiple or complex stones
-
Stones that are unlikely to be cleared effectively with less invasive approaches
Although PCNL is minimally invasive compared with traditional open surgery, it is still a surgical procedure and requires appropriate specialist evaluation.
Is Open Surgery Still Used for Kidney Stones?
Open stone surgery is now uncommon because modern minimally invasive procedures can treat most stones effectively.
In unusual or complex situations, surgical intervention may still be considered when standard endoscopic or percutaneous approaches are unsuitable.
The treating specialist determines the safest option based on individual anatomy and stone characteristics.
What Happens Before Renal Calculi Surgery?
A proper evaluation is important before selecting a procedure.
Medical Assessment
The doctor may review:
-
Pain and urinary symptoms
-
Previous kidney stones
-
Previous stone procedures
-
Medical conditions
-
Current medications
-
Previous infections
-
Kidney function
Imaging
Imaging may include:
-
Kidney ultrasound
-
X-ray when appropriate
-
Non-contrast CT scan
A CT scan can provide detailed information about stone size, location, and urinary obstruction.
Blood Tests
Depending on the patient's condition, tests may include:
-
Serum creatinine
-
eGFR
-
Blood urea nitrogen
-
Electrolytes
-
Complete blood count
-
Calcium
-
Uric acid
Urine Testing
Testing may include:
-
Urinalysis
-
Urine microscopy
-
Urine culture when infection is suspected
An active urinary infection may need to be treated before definitive stone removal.
Is a Ureteral Stent Needed?
A ureteral stent is a small flexible tube placed between the kidney and bladder to help maintain urine drainage.
A stent may be used:
-
After ureteroscopy
-
After treatment of certain obstructing stones
-
When the ureter needs temporary support
-
When swelling could temporarily affect urine flow
-
In selected situations before a definitive stone procedure
Not every patient requires a stent.
Some people experience temporary symptoms such as:
-
Frequent urination
-
Urgency
-
Burning during urination
-
Blood in the urine
-
Bladder discomfort
-
Flank discomfort
The stent should be removed or replaced according to the schedule provided by the treating urologist.
Recovery After Renal Calculi Treatment
Recovery depends on the procedure performed and the patient's overall health.
After treatment, some patients may experience:
-
Mild urinary discomfort
-
Blood in the urine
-
Increased urinary frequency
-
Temporary flank discomfort
-
Passage of small stone fragments
-
Fatigue
Patients should follow their specialist's instructions regarding activity, fluid intake, medications, and follow-up.
The recovery period can vary between ESWL, ureteroscopy, RIRS, and PCNL.
Warning Signs After Kidney Stone Surgery
Contact a healthcare professional promptly if you develop:
-
Fever or chills
-
Severe or worsening pain
-
Persistent vomiting
-
Difficulty passing urine
-
Very low or absent urine output
-
Heavy or persistent bleeding
-
Severe weakness or dizziness
Fever associated with urinary obstruction can indicate a serious infection and requires urgent assessment.
Can Medicines Replace Renal Calculi Surgery?
Sometimes observation or medication is appropriate, particularly for selected small stones that have a reasonable chance of passing naturally.
However, medicines cannot replace a stone-removal procedure in every situation.
Most common calcium-based kidney stones cannot be dissolved using medication.
Some uric acid stones may sometimes be dissolved through medically supervised urine alkalinization.
The appropriate approach depends on stone composition and the patient's clinical condition.
How to Prevent Renal Calculi From Returning
Removing a kidney stone does not necessarily prevent future stones.
Long-term prevention may involve:
Adequate Fluid Intake
Drinking enough fluid helps dilute stone-forming substances in urine. Fluid recommendations should be individualized for people with kidney failure, heart disease, or prescribed fluid restrictions.
Reduce Excess Sodium
High dietary sodium can increase urinary calcium in susceptible individuals and may increase the risk of calcium stones.
Maintain Appropriate Dietary Calcium
Severely restricting dietary calcium is generally not recommended for most people with calcium stones. The appropriate intake should be discussed with a healthcare professional.
Moderate Certain Foods When Indicated
People with specific metabolic abnormalities may need individualized recommendations regarding oxalate, animal protein, sugar, or other dietary factors.
Metabolic Evaluation
Patients with recurrent stones may benefit from stone analysis and a 24-hour urine evaluation to identify preventable risk factors.
What Is the Role of a Nephrologist in Kidney Stone Care?
A nephrologist focuses on kidney health and the medical factors that contribute to stone formation.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist, can help with:
-
Kidney function assessment
-
Evaluation of recurrent kidney stones
-
Metabolic risk assessment
-
Blood and urine investigations
-
Management of associated kidney disease
-
Dietary and preventive guidance
-
Long-term kidney health monitoring
When a stone requires a surgical or endoscopic procedure, care may involve a qualified urologist who specializes in stone removal procedures.
This collaborative approach helps address both the existing stone and the risk of future kidney problems.
Renal Calculi and Kidney Function
Most uncomplicated kidney stones do not permanently damage the kidneys when appropriately managed.
However, prolonged urinary obstruction, repeated infections, or untreated complicated stones can potentially affect kidney function.
People with:
-
A single functioning kidney
-
Chronic kidney disease
-
Recurrent obstruction
-
Repeated urinary infections
-
Large or complex stones
may require particularly careful evaluation and follow-up.
Frequently Asked Questions
What is the best surgical treatment for renal calculi?
There is no single best procedure for every patient. ESWL, ureteroscopy with laser lithotripsy, RIRS, and PCNL are selected according to stone size, location, anatomy, obstruction, infection, and kidney function.
Is renal calculi surgery painful?
Modern stone procedures are generally performed with appropriate anesthesia or sedation. Some temporary discomfort, urinary symptoms, or flank pain may occur during recovery.
How long does kidney stone surgery take?
Procedure time varies depending on the type of treatment, stone size, number of stones, location, and complexity.
Can a 10 mm kidney stone pass naturally?
A 10 mm stone is relatively large, and spontaneous passage is less likely than with smaller stones. However, the exact likelihood depends on location and other factors. A specialist should evaluate the stone before deciding between observation and active treatment.
Is PCNL used for large kidney stones?
Yes. PCNL is commonly considered for larger, complex, or staghorn kidney stones when it provides an appropriate approach for stone clearance.
Will kidney stones come back after surgery?
They can. Surgical removal treats the existing stone but does not necessarily eliminate the underlying tendency to form stones. Preventive evaluation and lifestyle changes can help reduce recurrence.
Conclusion
Renal calculi surgical treatment has advanced significantly, allowing many kidney stones to be treated with minimally invasive procedures. Depending on stone characteristics, treatment may include ESWL, ureteroscopy with laser lithotripsy, RIRS, or PCNL.
The right treatment should be selected after evaluating the stone's size and location, urinary obstruction, infection status, kidney function, anatomy, and overall health. Prompt treatment is particularly important when a stone causes obstruction together with infection or significant kidney impairment.
