What Is a Ureteral Stone?
A ureteral
stone is a stone that has moved from the kidney into the ureter.
As the stone
travels through this narrow tube, it may partially or completely block urine
flow, resulting in severe pain and other urinary symptoms.
The
likelihood of spontaneous passage depends on the stone's size and location.
Symptoms of Ureteral Stones
Symptoms may
develop suddenly and include:
- Severe flank pain.
- Pain radiating to the lower
abdomen or groin.
- Blood in the urine.
- Painful urination.
- Frequent urination.
- Nausea and vomiting.
- Difficulty passing urine.
- Fever and chills if infection
is present.
A fever
associated with an obstructed ureter is considered a medical emergency
requiring urgent treatment.
Causes and Risk Factors
Several
factors increase the risk of developing ureteral stones, including:
- Dehydration.
- Previous kidney stones.
- High salt intake.
- Diet rich in animal protein.
- Family history.
- Obesity.
- Certain metabolic disorders.
- Recurrent urinary tract
infections.
How Are Ureteral Stones
Diagnosed?
Diagnosis
may include:
- Medical history.
- Physical examination.
- Urinalysis.
- Blood tests.
- Ultrasound.
- Non-contrast CT scan.
- X-ray in selected cases.
These
investigations determine the stone's size, location, degree of obstruction, and
the condition of the affected kidney.
When Is Ureteral Stone Surgery
Needed?
Surgery may
be recommended when:
- The stone fails to pass
naturally.
- Severe pain persists despite
medication.
- Urine flow is blocked.
- Kidney function is threatened.
- Infection develops.
- The stone is too large for
spontaneous passage.
Treatment
decisions are individualized according to each patient's condition.
Treatment Options
Management
may include:
- Observation for small stones.
- Pain control.
- Medical expulsive therapy.
- Ureteroscopy.
- Laser lithotripsy.
- Temporary ureteral stenting.
- Percutaneous procedures in
selected complex cases.
Ureteroscopy and Laser
Lithotripsy
Ureteroscopy is one of the most common
treatments for ureteral stones.
A thin
endoscope is inserted through the urethra and bladder into the ureter without
external incisions.
The stone is
then:
- Removed intact using
specialized baskets, or
- Fragmented using a holmium
laser, allowing the fragments to pass naturally or be extracted during
the procedure.
This
minimally invasive technique provides high success rates with rapid recovery.
Ureteral Stent
A temporary
ureteral stent may be placed after surgery to maintain urine drainage while the
ureter heals.
The stent is
usually removed several days or weeks later during a simple outpatient
procedure.
Some
patients may temporarily experience urinary frequency, urgency, mild
discomfort, or blood in the urine while the stent remains in place.
Preparation Before Surgery
Before Ureteral
Stone Surgery, every patient undergoes a comprehensive preoperative
assessment that may include:
- Internal medicine evaluation.
- Cardiology assessment when
indicated.
- Psychological evaluation when
necessary.
- Anesthesia consultation.
- Urological examination.
- Blood and urine tests.
- Medical imaging.
The surgical
team explains the planned procedure, expected recovery, possible risks, and
postoperative care before treatment.
Recovery After Surgery
Recovery is
generally rapid because most procedures are minimally invasive.
Patients
receive instructions regarding:
- Hydration.
- Physical activity.
- Pain medication.
- Antibiotics if prescribed.
- Stent care when applicable.
- Follow-up appointments.
Most
patients resume normal daily activities within a few days, depending on the
procedure performed.
Possible Risks and
Complications
Although
complications are uncommon, they may include:
- Urinary tract infection.
- Bleeding.
- Temporary blood in the urine.
- Ureteral injury.
- Residual stone fragments.
- Temporary urinary discomfort
from the stent.
- Need for additional procedures.
Preventing Future Stones
Preventive
measures may include:
- Drinking adequate fluids.
- Reducing salt intake.
- Following dietary
recommendations.
- Treating metabolic disorders.
- Stone analysis after removal.
- Regular follow-up imaging when
indicated.
Patients
with recurrent stones may require additional metabolic evaluation.
A Message to Our Patients
Most
patients with Ureteral Stones no longer require traditional open
surgery. Modern Ureteral Stone Surgery, including ureteroscopy and laser
lithotripsy, allows effective stone removal through natural urinary passages
with minimal discomfort and faster recovery.
Our urology
team provides comprehensive evaluation, advanced endoscopic stone treatment,
individualized care, and preventive strategies to reduce the risk of future
stone formation.
Frequently Asked Questions
Can a ureteral stone pass without surgery?
Yes. Small
stones often pass naturally with hydration, pain medication, and medical
therapy.
Is ureteroscopy painful?
The
procedure is performed under anesthesia, so patients do not feel pain during
surgery.
What is laser lithotripsy?
Laser
lithotripsy uses a specialized laser to break the stone into tiny fragments
that can be removed or passed naturally.
Will I need a ureteral stent?
Not every
patient requires a stent, but it is commonly placed after ureteroscopy to
promote healing and urine drainage.
How long is recovery?
Most
patients return to normal daily activities within several days after minimally
invasive ureteral stone surgery.
Can ureteral stones come back?
Yes.
Patients who have had one urinary stone remain at increased risk of future
stones, making preventive measures and follow-up important.
When should I seek emergency medical care?
You should
seek urgent medical attention if severe pain is accompanied by fever, chills,
inability to urinate, or persistent vomiting, as these symptoms may indicate an
obstructed and infected urinary system requiring immediate treatment.
