What Is URSL?

URSL stands for Ureteroscopic Lithotripsy. It is a minimally invasive procedure used to treat stones within the ureter and, in selected cases, stones within the kidney.

During URSL, a small ureteroscope is introduced through the urethra and bladder and advanced into the ureter. The stone is visualised directly and fragmented using a suitable energy source, such as laser lithotripsy. Stone fragments may then be removed with specialised instruments or allowed to pass naturally depending on their size and the clinical situation.

Who May Need URSL?

URSL may be considered for patients with ureteric or selected kidney stones when endoscopic treatment is appropriate.

• Stones located in the ureter that are unlikely to pass naturally.
• Stones causing persistent pain, urinary obstruction or other stone-related symptoms.
• Stones that have not responded adequately to conservative treatment or shock wave lithotripsy.
• Selected kidney stones that are suitable for ureteroscopic treatment.
• Patients for whom ureteroscopy is considered appropriate based on stone size, location and anatomy.

Symptoms of Ureteric and Kidney Stones

Some stones may not cause symptoms. When symptoms occur, they may include:

• Sharp pain in the side, back, lower abdomen or groin.
• Pain that may come and go in waves.
• Blood in the urine.
• Pain or burning while urinating.
• Frequent or urgent need to urinate.
• Nausea or vomiting.
• Cloudy or foul-smelling urine, particularly when infection is present.

Causes of Ureteric and Kidney Stones

Kidney and ureteric stones form when certain minerals and substances become concentrated in the urine and form crystals. Calcium-containing stones are common, although uric acid, struvite and cystine stones can also occur.

Low fluid intake, dietary factors, metabolic abnormalities, certain medical conditions, urinary infections and a personal or family history of kidney stones can contribute to stone formation.

Risk Factors for Ureteric Stones

• Previous history of kidney or ureteric stones.
• Family history of kidney stones.
• Inadequate fluid intake.
• Dietary factors associated with stone formation.
• Certain metabolic or endocrine conditions.
• Some urinary tract infections.
• Obesity and associated metabolic factors.

Types of Kidney Stones

Kidney stones can be classified according to their chemical composition. Common types include:

How Are Ureteric Stones Diagnosed?

Diagnosis generally involves a medical history, physical examination, urine and blood tests and appropriate imaging. The choice of investigations depends on the patient's symptoms and clinical situation.

Common Diagnostic Tests

• Urinalysis and urine examination.
• Blood tests to assess kidney function and relevant metabolic factors.
• Ultrasound of the kidneys and urinary tract.
• X-ray in selected cases.
• Non-contrast CT scan when appropriate to determine stone size, location and urinary obstruction.
• Stone analysis when a stone or fragment is available.

Imaging helps the urologist determine the location and size of the stone, the degree of obstruction and whether URSL or another treatment approach may be appropriate.

When Should You See a Urologist?

You should consider consulting a urologist if you have persistent or recurrent flank pain, blood in the urine, recurrent urinary infections, difficulty passing urine or imaging that shows a ureteric or kidney stone.

Ureteric Stone Treatment Options

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

URSL is commonly used for ureteric stones requiring active endoscopic treatment. The choice between URSL, SWL, RIRS, PCNL or observation depends on the individual stone and patient factors.

How Is URSL Surgery Performed?

The exact technique varies according to the patient's anatomy, stone characteristics and treatment plan. In general, URSL involves the following steps:

Preparation Before URSL Surgery

Before URSL, the urologist will review your medical history, medicines, allergies, imaging and laboratory reports. The exact preparation depends on your health and the planned procedure.

• Blood and urine investigations may be required.
• Imaging such as ultrasound or CT may be reviewed for treatment planning.
• Any urinary infection should be identified and appropriately treated before stone treatment.
• Tell your doctor about blood thinners, supplements and other medicines you are taking.
• Follow the hospital's instructions regarding fasting and medicines before anesthesia.

Recovery After URSL

Recovery after URSL varies depending on the stone size and location, procedure complexity, presence of a ureteral stent and the patient's overall health.

Because URSL is performed through the natural urinary passage and does not require an external incision, recovery may be relatively quick in appropriate cases. However, the exact time needed to return to work, exercise and other normal activities should be determined by the treating urologist.

Temporary urinary frequency, mild discomfort or blood in the urine can occur after the procedure, particularly when a ureteral stent has been placed.

Post-Treatment Care After URSL

• Take prescribed medicines according to your doctor's instructions.
• Drink adequate fluids unless your doctor has advised fluid restriction.
• Attend scheduled follow-up appointments.
• If a ureteral stent is placed, follow the instructions regarding stent removal or follow-up.
• Report fever, worsening pain, heavy bleeding, difficulty passing urine or other unexpected symptoms promptly.

Diet & Lifestyle After Stone Treatment

Preventing future kidney and ureteric stones is an important part of long-term stone care. Recommendations should be tailored according to the type of stone and any identified metabolic risk factors.

• Drink adequate fluids unless your doctor has advised fluid restriction.
• Limit excessive salt intake.
• Follow dietary recommendations appropriate for your specific stone type.
• Maintain a healthy body weight and remain physically active as appropriate.
• Follow personalised dietary advice if metabolic testing identifies a specific stone-forming risk.

Possible Complications of URSL

URSL is a minimally invasive procedure, but like other surgical procedures, it carries potential risks. Individual risk depends on the patient's health, stone characteristics, urinary tract anatomy and procedure complexity.

• Urinary tract infection.
• Fever or postoperative infection.
• Blood in the urine.
• Temporary urinary discomfort or increased urinary frequency.
• Ureteral injury, which may rarely result in a ureteral stricture.
• Residual stone fragments requiring further treatment.
• Temporary discomfort related to a ureteral stent.

Benefits of URSL

• Provides direct visual access to the ureter and selected kidney stones.
• Does not require an external skin incision.
• Allows stones to be fragmented under direct visual guidance.
• Can be useful for stones that are unsuitable for or have not responded adequately to other treatment approaches.
• Generally involves less tissue disruption than traditional open stone surgery.

Risks and Limitations of URSL

Although URSL is minimally invasive, it is not completely risk-free. Infection, bleeding, ureteral injury, stent-related discomfort and residual stone fragments are possible.

Very large or complex stone burdens may require staged treatment or another approach such as RIRS or PCNL, depending on the stone's location, size and overall burden.

The final treatment plan depends on the number, size and location of stones, urinary obstruction, kidney and ureter anatomy, urinary infection, previous procedures and other individual medical factors.

URSL Treatment Outcome and Follow-Up

The expected outcome after URSL depends on stone size, location, composition, urinary tract anatomy and other patient-specific factors.

Many ureteric stones can be treated endoscopically, but larger or more complex stones may require staged procedures or additional treatment.

Follow-up imaging may be recommended to assess residual stone fragments and confirm the status of the urinary tract.

Cost of URSL Surgery in Thane

The cost of URSL varies depending on the stone size and location, number of stones, procedure complexity, hospital facilities, investigations, anesthesia, laser equipment and individual patient requirements.

For an accurate estimate, patients should discuss the expected treatment plan and associated hospital costs with the doctor after evaluation.
