Introduction
Ureteral lithotripsy is a treatment approach used to break a stone located in the ureter into smaller fragments so that it can be removed or passed through the urinary tract. Ureter stones can cause severe pain, blood in the urine, urinary obstruction, nausea, and other urinary symptoms.
The most appropriate treatment depends on factors such as the size and location of the stone, degree of obstruction, symptoms, kidney function, presence of infection, stone composition, and the patient's overall health.
Some small ureter stones may pass naturally with appropriate medical management and monitoring. Others may require active stone removal. Depending on the stone and patient factors, treatment may include ureteroscopy with laser lithotripsy, shock wave lithotripsy, or another appropriate procedure.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist, provides comprehensive evaluation of kidney and urinary stone disease, kidney function assessment, metabolic evaluation, medical management, and prevention planning. When a procedure is required, treatment can be coordinated with an experienced urologist.
What Is a Ureter Stone?
The ureters are narrow tubes that carry urine from the kidneys to the bladder.
A ureter stone develops when a kidney stone moves from the kidney into the ureter.
Because the ureter is relatively narrow, a stone can become lodged and interfere with urine flow.
Depending on its location, a ureter stone may be described as:
-
Upper ureter stone
-
Middle ureter stone
-
Lower ureter stone
-
Ureterovesical junction stone
The location can influence both the symptoms and treatment approach.
What Is Ureteral Lithotripsy?
Lithotripsy means breaking a urinary stone into smaller fragments.
For ureter stones, lithotripsy may be performed using different techniques.
One common approach is ureteroscopy with laser lithotripsy, in which a urologist passes a thin instrument through the urinary tract to reach the stone. A laser is then used to fragment the stone, and the pieces may be removed using specialized instruments.
Another option in selected cases is Extracorporeal Shock Wave Lithotripsy (ESWL), which uses externally generated shock waves to fragment certain stones without making an incision.
The best technique depends on the individual stone and patient characteristics.
When Is Ureteral Lithotripsy Recommended?
Not every ureter stone requires lithotripsy.
A small stone may be observed when:
-
It has a reasonable chance of passing naturally
-
There is no significant obstruction
-
There is no infection
-
Kidney function is stable
-
Pain is manageable
-
Appropriate follow-up is possible
Active treatment may be considered when:
-
The stone is unlikely to pass naturally
-
Pain persists despite medical treatment
-
The stone causes significant obstruction
-
Kidney function is affected
-
The stone remains in the ureter
-
There are recurrent complications
-
The patient prefers definitive treatment after discussing options
The decision should be based on medical evaluation rather than stone size alone.
Symptoms of Ureter Stones
Ureter stones can produce symptoms when they obstruct or irritate the urinary tract.
Common symptoms include:
Severe Flank Pain
Pain may begin in the side or back and travel toward the lower abdomen or groin.
Pain That Comes and Goes
Ureteral stone pain can occur in waves as the ureter contracts around the stone.
Blood in the Urine
Stones can irritate the urinary tract and cause visible or microscopic blood in the urine.
Nausea and Vomiting
Severe pain may be accompanied by nausea or vomiting.
Frequent Urination
A stone near the lower end of the ureter may cause urinary frequency or urgency.
Burning During Urination
Some patients experience discomfort while passing urine.
Difficulty Passing Urine
Significant obstruction can interfere with normal urine flow.
How Is a Ureter Stone Diagnosed?
Before deciding on lithotripsy, the stone needs to be evaluated carefully.
Medical Evaluation
Your doctor may review:
-
Pain location and duration
-
Previous kidney stones
-
Urinary symptoms
-
Previous stone procedures
-
Medical conditions
-
Current medications
-
Kidney disease history
Blood Tests
Depending on the clinical situation, investigations may include:
-
Serum creatinine
-
eGFR
-
Blood urea nitrogen
-
Electrolytes
-
Calcium
-
Uric acid
-
Complete blood count when infection is suspected
These tests help assess kidney function and identify associated abnormalities.
Urine Testing
Investigations may include:
-
Routine urinalysis
-
Urine microscopy
-
Urine culture when infection is suspected
-
Urine pH
-
Protein or albumin testing when indicated
Urine culture is particularly important when there are symptoms or findings suggesting infection.
Imaging
Imaging helps determine the stone's:
-
Size
-
Location
-
Number
-
Degree of obstruction
Possible investigations include:
-
Kidney and urinary tract ultrasound
-
Non-contrast CT scan
-
X-ray in selected situations
CT can provide detailed information about ureteral stones when clinically appropriate.
Ureteroscopy With Laser Lithotripsy
One of the commonly used procedures for ureter stones is ureteroscopy with laser lithotripsy.
During the procedure:
-
The patient receives appropriate anesthesia.
-
A thin ureteroscope is passed through the urinary tract.
-
The urologist identifies the ureter stone.
-
A laser is used to fragment the stone.
-
Stone fragments may be removed using specialized instruments.
-
A temporary ureteral stent may be placed when necessary.
The exact procedure varies depending on stone size, location, anatomy, and clinical circumstances.
What Is Laser Lithotripsy?
Laser lithotripsy uses controlled laser energy to break a urinary stone into smaller fragments.
Depending on the stone, the urologist may:
-
Fragment the stone into removable pieces
-
Break it into smaller particles
-
Remove accessible fragments
The technique allows direct treatment of the stone under visualization.
Shock Wave Lithotripsy for Ureter Stones
Extracorporeal Shock Wave Lithotripsy, or ESWL, uses shock waves generated outside the body to break selected urinary stones into smaller fragments.
ESWL may be considered for appropriate stones depending on:
-
Stone size
-
Stone location
-
Stone density or composition
-
Patient anatomy
-
Degree of obstruction
-
Presence of infection
Not every ureter stone is suitable for ESWL.
Ureteral Stent and Lithotripsy
A ureteral stent is a thin tube placed inside the ureter to help maintain urine drainage.
A stent may be used:
-
Before a procedure in selected cases
-
After stone treatment
-
When swelling could temporarily interfere with urine flow
-
When the ureter needs support after stone removal
Not every patient requires a stent.
What Symptoms Can a Stent Cause?
Temporary stent-related symptoms may include:
-
Frequent urination
-
Urinary urgency
-
Burning while urinating
-
Blood in the urine
-
Bladder discomfort
-
Flank discomfort, sometimes during urination
These symptoms usually improve after the stent is removed.
The treating urologist will determine when the stent should be removed or changed.
Is Ureteral Lithotripsy Painful?
The procedure itself is generally performed under appropriate anesthesia, so significant pain during the procedure is avoided.
After treatment, some patients may experience:
-
Mild urinary discomfort
-
Blood in the urine
-
Bladder irritation
-
Flank discomfort
-
Temporary stent-related symptoms
Pain-management instructions should be provided by the treating medical team.
Recovery After Ureteral Lithotripsy
Recovery varies according to the procedure performed and the patient's overall health.
After ureteroscopy with laser lithotripsy, patients may be advised to:
-
Drink fluids according to medical advice
-
Take prescribed medicines
-
Avoid strenuous activities temporarily if advised
-
Monitor urine symptoms
-
Attend the scheduled follow-up
-
Return for stent removal if one was placed
Many patients resume normal activities relatively quickly, but recovery time varies.
Possible Risks and Complications
Like other medical procedures, ureteral lithotripsy can have potential complications.
These may include:
-
Blood in the urine
-
Urinary discomfort
-
Urinary tract infection
-
Ureteral injury
-
Temporary urinary obstruction
-
Residual stone fragments
-
Need for additional treatment
-
Stent-related symptoms
Serious complications are uncommon but should be discussed with the treating urologist before the procedure.
Infection and Ureteral Obstruction: An Important Warning
A urinary infection occurring behind an obstructed ureter can become a medical emergency.
Seek urgent medical care if you have:
-
Fever or chills
-
Severe flank pain
-
Vomiting
-
Reduced urine output
-
Difficulty passing urine
-
Known ureteral obstruction with infection symptoms
When infection and obstruction occur together, antibiotics alone may not be enough. Urgent drainage of the urinary system may be necessary, often using a ureteral stent or nephrostomy, followed by definitive stone treatment once clinically appropriate.
Can a Ureter Stone Pass Without Lithotripsy?
Yes, some ureter stones pass naturally.
The likelihood depends on factors such as:
-
Stone size
-
Stone location
-
Stone shape
-
Degree of obstruction
-
Patient anatomy
-
Symptoms
-
Kidney function
Smaller stones generally have a better chance of spontaneous passage than larger stones.
Your doctor may recommend observation when natural passage is reasonably likely and there are no complications.
Medicines Before or Instead of Lithotripsy
Selected patients may receive medicines to:
-
Control pain
-
Reduce nausea
-
Facilitate passage of certain ureter stones
-
Treat infection when present
An alpha blocker may sometimes be considered for selected distal ureteral stones.
Medication is not appropriate for every patient or every stone, and treatment should be prescribed based on individual circumstances.
Role of a Nephrologist in Ureter Stone Treatment
A nephrologist can play an important role in the medical evaluation and prevention of stone disease.
A nephrologist may help with:
-
Kidney function assessment
-
Metabolic evaluation
-
Recurrent stone investigation
-
Blood and urine testing
-
Dietary recommendations
-
Prevention of future stones
-
Management of associated CKD
-
Evaluation of electrolyte or metabolic abnormalities
A urologist generally performs ureteroscopy, laser lithotripsy, ESWL, and other stone-removal procedures.
Collaboration between nephrology and urology can provide comprehensive care when both medical and procedural treatment are needed.
Preventing Future Ureter Stones
Treatment of the current stone is only one part of kidney stone care.
To reduce recurrence, your doctor may recommend:
Adequate Fluid Intake
Maintaining adequate urine volume helps dilute stone-forming substances.
Fluid recommendations should be individualized, especially for people with kidney, heart, or other medical conditions.
Reduce Excess Sodium
High sodium intake can increase urinary calcium in some people and contribute to calcium stone formation.
Follow a Personalized Diet
Dietary recommendations depend on the type of stone and metabolic risk factors.
Maintain Appropriate Dietary Calcium
Most calcium-stone patients should not eliminate dietary calcium completely. The appropriate intake should be discussed with a healthcare professional.
Limit Excessive Animal Protein When Appropriate
High animal-protein intake can contribute to certain metabolic changes associated with stone formation.
Complete Metabolic Evaluation for Recurrent Stones
Patients with repeated stones may benefit from blood testing and 24-hour urine evaluation to identify preventable risk factors.
What Happens After Lithotripsy?
Follow-up may be required to determine whether:
-
The stone has been completely removed
-
Fragments remain
-
Urine flow has returned to normal
-
The kidney has recovered from obstruction
-
A stent needs to be removed
-
Additional treatment is necessary
Follow-up imaging and urine or blood testing may be recommended according to the individual case.

Frequently Asked Questions
What is ureteral lithotripsy?
Ureteral lithotripsy is a treatment used to break a stone in the ureter into smaller fragments so it can be removed or passed through the urinary tract. Laser lithotripsy is commonly performed during ureteroscopy.
Is ureteral lithotripsy the same as kidney stone surgery?
It can be considered a type of active stone treatment, but the exact procedure depends on where the stone is located. Ureteroscopy with laser lithotripsy is commonly used for ureter stones.
How long does ureteral lithotripsy take?
Procedure time varies depending on stone size, location, number of stones, anatomy, and the technique used. Your urologist can provide a more accurate estimate after evaluating your imaging.
Will I need a ureteral stent after lithotripsy?
Not everyone needs a stent. A stent may be placed when the urologist believes it will support urine drainage or help the ureter recover after treatment.
Can a ureter stone pass naturally?
Yes. Some small ureter stones can pass without a procedure. The likelihood depends on stone size, location, obstruction, symptoms, and kidney function.
Is laser lithotripsy safe?
Laser lithotripsy is an established treatment for urinary stones, but, like any procedure, it carries potential risks such as infection, bleeding, ureteral injury, residual stones, or the need for additional treatment.
Can ureteral stones damage the kidney?
A persistent obstructing ureter stone can impair urine drainage and, if untreated, may contribute to kidney damage. The risk is particularly important when obstruction is severe, prolonged, or associated with infection.
Can I drink a lot of water to push out a ureter stone?
Adequate hydration may support stone passage when appropriate, but forcing excessive water is not a safe substitute for medical treatment when significant obstruction, vomiting, reduced urine output, or kidney dysfunction is present.
Which doctor treats ureter stones?
A nephrologist can evaluate kidney function, metabolic risk factors, and prevention strategies. A urologist generally performs procedures such as ureteroscopy, laser lithotripsy, and ESWL.
Conclusion
Ureteral lithotripsy is an important treatment option for selected patients with ureter stones that are unlikely to pass naturally or are causing persistent symptoms, obstruction, or other complications. Ureteroscopy with laser lithotripsy allows the urologist to directly access and fragment the stone, while ESWL may be suitable for selected stones.
Not every ureter stone requires a procedure. Some smaller uncomplicated stones may pass naturally with appropriate medical management and follow-up. The choice of treatment depends on stone size, location, obstruction, infection, kidney function, and individual patient factors.
