URS lithotripsy is a minimally invasive procedure used to treat selected kidney and ureter stones.

URS stands for ureteroscopy. During the procedure, a thin camera-equipped instrument called a ureteroscope is passed through the natural urinary passage to reach the stone.

Once the stone is located, it can be broken into smaller fragments using an energy source, commonly a laser. The fragments may then be removed with specialized instruments or allowed to pass naturally, depending on their size and the clinical situation.

Unlike traditional open surgery, ureteroscopy does not usually require an external incision.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides kidney-focused evaluation for patients with stone disease and can coordinate appropriate urological care when a stone procedure is required.

When Is URS Lithotripsy Recommended?

Not every kidney stone needs ureteroscopy.

A doctor may consider URS when a stone:

• Is unlikely to pass naturally

• Causes persistent pain

• Blocks urine flow

• Remains in the ureter

• Causes recurrent urinary problems

• Is associated with impaired kidney function

• Has not responded to appropriate conservative treatment

• Is located in an area where ureteroscopy is considered suitable

The decision depends on the stone's size, location, composition, symptoms, urinary anatomy and the patient's overall health.

Can URS Treat Both Kidney and Ureter Stones?

Yes. Ureteroscopy can be used for stones in different parts of the urinary tract.

For a ureter stone, the ureteroscope can be advanced directly to the stone.

For selected kidney stones, the scope can be advanced into the kidney through the urinary tract, allowing the surgeon to access and treat stones within the collecting system.

The exact approach depends on the location and characteristics of the stone.

How Does URS Lithotripsy Work?

The procedure generally follows several stages.

1. Anesthesia

URS is usually performed under anesthesia so that the patient remains comfortable during the procedure.

The type of anesthesia depends on the patient's health and the planned procedure.

2. Insertion of the Ureteroscope

The surgeon carefully passes a thin ureteroscope through:

• Urethra

• Bladder

• Ureter

No large external incision is generally required.

3. Locating the Stone

The camera on the ureteroscope provides a view of the urinary tract and allows the surgeon to identify the stone.

4. Breaking the Stone

A laser or another appropriate energy source can be used to fragment the stone.

The fragments may be:

• Removed using a retrieval basket

• Broken into very small pieces

• Left to pass naturally when appropriate

5. Stent Placement

In some patients, a temporary ureteral stent is placed after the procedure.

A stent can help maintain urine drainage while the ureter heals and swelling settles.

A stent is not required in every case.

What Is Laser Lithotripsy During URS?

Laser lithotripsy uses laser energy to break a kidney or ureter stone into smaller pieces.

The surgeon can adjust the technique depending on:

• Stone size

• Stone hardness

• Stone location

• Desired fragment size

• Patient anatomy

The goal may be to remove larger fragments or reduce the stone to small pieces that can pass through the urinary tract.

Is URS Lithotripsy Painful?

The procedure itself is performed under anesthesia, so the patient should not experience the procedure in the usual way.

Afterward, some patients may experience:

• Mild burning while urinating

• Urinary frequency

• Blood in urine

• Bladder discomfort

• Flank discomfort

• Stent-related symptoms

These symptoms are often temporary, but significant or worsening pain should be reported to the treating team.

Why Might a Ureteral Stent Be Used?

A ureteral stent is a small flexible tube placed inside the ureter.

It may be recommended when the doctor wants to:

• Maintain urine drainage

• Reduce the effect of ureteral swelling

• Support healing

• Help manage obstruction

• Facilitate treatment of selected complicated stones

Stent placement depends on the procedure and individual circumstances.

What Does a Stent Feel Like?

Some people with a temporary ureteral stent experience:

• Frequent urination

• Urgency

• Bladder discomfort

• Flank discomfort during urination

• Mild blood in urine

The intensity varies from person to person.

Patients should follow the instructions provided by their treating doctor regarding stent care and removal.

How Long Does URS Lithotripsy Take?

The duration varies depending on:

• Number of stones

• Stone size

• Stone location

• Stone hardness

• Anatomy

• Whether a stent is required

• Complexity of the procedure

A straightforward procedure may be relatively short, while larger or multiple stones can require more time or staged treatment.

What Happens After URS Lithotripsy?

After the procedure, the patient is monitored while recovering from anesthesia.

Depending on the case, discharge may occur the same day or after observation.

Patients may be advised to:

• Take prescribed medicines

• Drink an appropriate amount of fluid

• Monitor urine

• Follow activity restrictions if advised

• Return for follow-up

• Have a stent removed at the recommended time if one was placed

The exact recovery instructions vary by procedure.

URS Lithotripsy Recovery

Recovery is generally faster than with open stone surgery because there is usually no large external incision.

Temporary symptoms can include:

• Mild urinary discomfort

• Increased urinary frequency

• Small amounts of blood in urine

• Mild pelvic or flank discomfort

• Tiredness after anesthesia

Patients should contact their healthcare team if symptoms are severe, persistent or worsening.

How Soon Can You Return to Normal Activities?

The time required to resume normal activities depends on the complexity of the procedure and the patient's overall health.

People with uncomplicated procedures may return to routine activities relatively quickly, while those who undergo more extensive treatment may require additional recovery time.

Your treating surgeon should provide individualized instructions about:

• Exercise

• Heavy lifting

• Work

• Driving

• Sexual activity

• Travel

Possible Risks of URS Lithotripsy

Ureteroscopy is commonly used for urinary stones, but like any medical procedure, it carries potential risks.

Possible complications include:

• Urinary tract infection

• Bleeding

• Ureteral injury

• Ureteral swelling

• Temporary urinary discomfort

• Stone fragments remaining behind

• Need for repeat treatment

• Stent-related symptoms

• Rare ureteral narrowing or other complications

The risk depends on the patient's anatomy, stone characteristics and procedure complexity.

Can URS Remove a Stone Completely?

The goal is often complete stone clearance, but this cannot always be guaranteed in a single procedure.

Factors affecting stone clearance include:

• Stone burden

• Number of stones

• Stone composition

• Location

• Kidney anatomy

• Procedure access

• Residual fragments

Larger or multiple stones may require more than one treatment session.

URS vs Shock-Wave Lithotripsy

Both treatments can be used for selected kidney and ureter stones, but they work differently.

URS

• Uses a scope inserted through the urinary tract

• Allows direct visualization of the stone

• Can use laser fragmentation

• Often provides high stone-free rates for appropriately selected stones

• May require temporary stent placement

Shock-Wave Lithotripsy

• Uses externally generated shock waves

• Does not require passage of a scope into the urinary tract

• Breaks the stone into fragments

• Fragment passage may take time

• Effectiveness depends on stone size, location and other factors

The appropriate option should be selected after evaluating the individual stone.

URS vs PCNL

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

PCNL involves creating a small access tract through the skin into the kidney.

URS is often considered for selected smaller or appropriately located stones, while PCNL may be preferred for a high stone burden.

The choice depends on stone size, location, anatomy and other clinical factors.

Can URS Be Used for a 5 mm Stone?

A 5 mm stone may sometimes pass naturally, depending on where it is located.

URS may be considered if the stone remains stuck, causes persistent symptoms, produces obstruction or has other clinical indications for intervention.

A 5 mm measurement alone does not determine whether surgery is necessary.

What If the Stone Causes an Infection?

A stone causing urinary obstruction together with infection can be a medical emergency.

In such cases, the immediate priority may be to establish adequate urinary drainage and treat the infection.

Definitive stone removal may be performed later when the infection has been appropriately controlled.

Patients with fever, chills, severe flank pain and known urinary obstruction should seek urgent medical care.

How Can Kidney Stones Be Prevented After URS?

Removing the current stone does not necessarily prevent another stone from forming.

Long-term prevention may include:

Adequate Fluid Intake

Appropriate fluid intake helps dilute urine.

The recommended amount should be individualized, particularly for people with kidney or heart conditions.

Lower Excess Sodium

High salt intake can increase urinary calcium in some individuals.

Reducing excessive sodium may therefore help reduce the risk of certain stones.

Identify Stone Composition

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

Metabolic Evaluation

People with recurrent stones or specific risk factors may benefit from blood tests and a 24-hour urine evaluation.

Address Medical Risk Factors

Conditions such as high uric acid, certain metabolic disorders and recurrent urinary infections may require specific management.

What Tests May Be Needed Before URS?

Before a procedure, the medical team may review:

• Urine testing

• Urine culture

• Kidney function

• Blood counts

• Electrolytes

• Imaging

• Stone size and location

• Medical and surgical history

• Current medications

Testing helps identify infection, assess procedural risk and plan the appropriate treatment.

When Should You Seek Medical Help After URS?

Contact your treating medical team promptly for:

• High fever

• Chills

• Severe or worsening pain

• Heavy bleeding in urine

• Difficulty passing urine

• Persistent vomiting

• Severe weakness

• Rapid deterioration

A fever after urinary stone treatment can indicate infection and should not be ignored.

URS Lithotripsy and Kidney Function

A urinary stone can sometimes obstruct urine flow and affect kidney function.

If obstruction is prolonged or associated with infection, kidney injury can occur.

Appropriate treatment may help restore urine drainage and protect kidney function.

Patients with existing chronic kidney disease may require closer monitoring of creatinine and eGFR before and after stone treatment.

Frequently Asked Questions

What is URS lithotripsy?

URS lithotripsy is a minimally invasive stone treatment in which a ureteroscope is passed through the urinary tract to reach a kidney or ureter stone, which can then be fragmented, commonly with laser energy.

Is URS better than shock-wave lithotripsy?

Neither procedure is universally better. The choice depends on stone size, location, composition, anatomy, symptoms and patient factors.

How long does it take to recover from ureteroscopy?

Recovery varies. Many patients with uncomplicated procedures resume routine activities relatively quickly, but the presence of a stent or treatment of larger stones can affect recovery.

Is a stent always required after URS?

No. A stent may be placed when clinically appropriate, but it is not necessary in every uncomplicated procedure.

Can URS damage the kidney?

Ureteroscopy is designed to treat urinary stones while preserving kidney function, but every procedure has potential risks. Rare complications can involve the ureter or urinary tract.

Can kidney stones come back after URS?

Yes. URS removes or fragments the treated stone but does not necessarily eliminate the factors that caused stone formation. Prevention and metabolic evaluation can help reduce recurrence.

Conclusion

URS lithotripsy provides a minimally invasive option for treating selected kidney and ureter stones. By allowing direct access to the stone, ureteroscopy can enable fragmentation and removal without the large incision associated with traditional open surgery.

Whether URS is appropriate depends on the stone's size, location, symptoms, obstruction, infection status and the patient's overall health. Some stones can pass naturally, while others require ureteroscopy, shock-wave treatment or PCNL.

After stone treatment, prevention is equally important. Appropriate hydration, dietary measures, stone analysis and metabolic evaluation can help reduce the likelihood of future stones.

For kidney-function assessment and recurrent stone management, consult Dr. Sandip Prabhakar Bhurke at Prabhakar Bhurke Clinic. When a stone procedure is required, appropriate coordination with a qualified urologist is essential.
