What Is a Ureteral Stone?
A ureteral stone is a hard mineral deposit that travels from the kidney
into the ureter. Because the ureter is relatively narrow, a stone can become
stuck and partially or completely interfere with the normal passage of urine.
Small stones may sometimes pass naturally. Larger stones, impacted stones,
or stones causing persistent obstruction may require medical or surgical
treatment.
When Is Ureteral Stone Surgery Necessary?
Treatment is considered when a stone is unlikely to pass naturally or is
causing significant problems.
Your urologist may recommend Ureteral Stone Surgery in situations
such as:
- Persistent
or severe pain.
- Urinary
obstruction.
- A stone
that remains lodged in the ureter.
- Recurrent
emergency visits because of symptoms.
- Infection
associated with urinary obstruction.
- Impaired
kidney function.
- A stone
that has not passed with conservative treatment.
- A stone
size or location that makes spontaneous passage unlikely.
The treatment plan depends on the individual patient's condition rather
than stone size alone.
Symptoms of Ureteral Stones
Common symptoms may include:
- Sudden
severe pain in the side or lower back.
- Pain
radiating toward the abdomen or groin.
- Blood
in the urine.
- Nausea
or vomiting.
- Frequent
urination.
- Burning
during urination.
- Difficulty
passing urine.
Fever or chills associated with urinary obstruction may indicate an
infection and require urgent medical assessment.
How Are Ureteral Stones Diagnosed?
Diagnosis usually begins with a medical history and physical examination.
Depending on the clinical situation, the urologist may request:
- Urinalysis.
- Blood
tests.
- Ultrasound.
- Imaging
of the urinary tract.
- Non-contrast
CT when appropriate.
Imaging helps determine the stone's size, location, degree of obstruction,
and condition of the urinary system.
Ureteroscopy for Ureteral Stones
Ureteroscopy (URS) is a minimally invasive technique used to reach and
treat stones in the ureter.
The surgeon passes a thin ureteroscope through the urethra and bladder into
the ureter. A small camera provides direct visualization of the stone.
Depending on its size, the stone can be removed using a small basket or broken
into smaller fragments.
No external skin incision is required, which is one of the important
advantages of ureteroscopy.
Laser Lithotripsy
For stones that cannot be removed intact, the surgeon may use a laser to
fragment them into smaller pieces.
Laser lithotripsy allows the urologist to target the stone precisely through the
ureteroscope. Depending on the situation, fragments can be extracted with a
basket or allowed to pass naturally after being reduced to smaller pieces.
Modern laser technology has become an important part of minimally invasive
stone treatment, with ongoing advances in laser systems and endoscopic
equipment.
Ureteral Stent Placement
After ureteroscopy, the surgeon may place a temporary ureteral stent.
The stent is a thin tube that helps maintain urine drainage from the kidney
to the bladder while the ureter recovers. It may be particularly useful when
the ureter has been irritated during the procedure or when temporary support is
needed.
A stent is not required in every patient. If one is placed, the urologist
will explain when and how it should be removed.
Preparing for Ureteral Stone Surgery
Before the procedure, the medical team evaluates the patient's general
health and urinary system.
Preparation may include:
- Medical
history review.
- Physical
examination.
- Urine
testing.
- Blood
tests.
- Imaging
to identify the stone.
- Medication
review.
- Anesthesia
assessment.
- Instructions
regarding fasting before the procedure.
If there is an active urinary infection, it must be appropriately addressed
before elective stone treatment. The timing and type of intervention depend on
the patient's clinical condition.
Recovery After Ureteral Stone Surgery
Recovery depends on the stone characteristics and the procedure performed.
After ureteroscopy, patients may experience temporary:
- Burning
during urination.
- Increased
urinary frequency.
- Mild
discomfort.
- Small
amounts of blood in the urine.
These symptoms generally improve as the urinary tract recovers.
Patients should follow their urologist's instructions regarding hydration,
physical activity, medications, and follow-up. If a stent has been inserted,
additional instructions will be provided.
Possible Risks and Complications
Although ureteroscopy is minimally invasive, complications can occur.
Potential risks include:
- Urinary
tract infection.
- Bleeding.
- Temporary
discomfort.
- Ureteral
irritation.
- Ureteral
injury.
- Difficulty
removing a large or impacted stone.
- Residual
stone fragments.
- Ureteral
narrowing in uncommon cases.
The individual risk depends on the stone, anatomy, medical history, and
complexity of the procedure.
Why Choose a Specialized Urology Team?
Successful ureteral stone treatment requires more than simply removing the
stone. The urologist must consider its location, size, obstruction, anatomy,
and the patient's overall condition when selecting the most appropriate
approach.
Modern endourology combines high-definition imaging, specialized
ureteroscopes, laser technology, and other minimally invasive techniques to
provide targeted treatment while limiting unnecessary surgical trauma.
A Message to Our Patients
If you have a ureteral stone that is causing persistent pain, obstruction,
or other complications, modern minimally invasive treatments can often remove
the stone without open surgery. Our urology team evaluates each patient
individually and selects the most appropriate approach, including ureteroscopy
and laser lithotripsy when indicated.
Frequently Asked Questions
Can every ureteral
stone be treated without surgery?
No. Some small stones may pass naturally, but larger, impacted,
obstructing, or complicated stones may require active treatment.
What is ureteroscopy?
Ureteroscopy is a minimally invasive procedure in which a small camera is
passed through the urinary tract into the ureter. The stone can then be removed
or fragmented.
Is laser lithotripsy
painful?
The procedure is performed under anesthesia, so the patient does not
normally feel the laser treatment itself. Temporary urinary discomfort can
occur during recovery.
Will I need a ureteral
stent after surgery?
Not necessarily. A temporary stent may be placed when the urologist
believes it will support urine drainage or healing.
How long does recovery
take?
Recovery varies according to the procedure and individual circumstances.
Many patients can resume light daily activities relatively quickly, while
complete recovery may take longer depending on the complexity of treatment.
Can ureteral stones
come back?
Yes. Removing a stone treats the current obstruction but does not eliminate
the underlying tendency to form urinary stones. Follow-up evaluation and
preventive measures may help reduce the risk of recurrence.
