Ureteroscopy & Laser Lithotripsy: Stone Removal Explained at THANC Hospital, Chennai
Are you or your loved one struggling with severe flank pain, blood in urine, or frequent urinary tract infections? These symptoms often signal the presence of kidney or ureteral stones — a common yet painful condition that can disrupt daily life.
At THANC Hospital, Chennai, we provide advanced, minimally invasive solutions for stone removal, including Ureteroscopy (URS) and Laser Lithotripsy, ensuring precise treatment, rapid recovery, and minimal discomfort.
Read on to understand the entire process, benefits, safety measures, and recovery timeline — and learn how our expert urologists help patients regain comfort and kidney health efficiently.
Understanding Urinary Stones and Their Formation
Urinary stones (urolithiasis) are solid crystal deposits formed from minerals and salts in the urine. They can develop anywhere along the urinary tract — kidneys, ureters, bladder, or urethra — and vary in size from tiny grains to large obstructing stones.
Common Causes
Stones form when urine becomes concentrated, allowing minerals to crystallize. Key contributing factors include:
- Inadequate fluid intake or dehydration
- High intake of salt, protein, or oxalate-rich foods
- Recurrent urinary infections
- Genetic predisposition or metabolic disorders
- Obesity and sedentary lifestyle
Types of Stones
- Calcium oxalate / phosphate stones (most common)
- Uric acid stones
- Struvite (infection) stones
- Cystine stones (rare, inherited)
Understanding the stone type helps our team at Thanc Hospital plan targeted therapy and preventive care.
Recognizing Symptoms of Urinary Stones
Urinary stones can cause a range of discomforts, depending on their size and position. Typical symptoms include:
- Sharp, colicky pain in the lower back, side, or groin
- Burning sensation or pain during urination
- Blood in urine (hematuria)
- Frequent urge to urinate or difficulty passing urine
- Nausea or vomiting during pain episodes
- Fever and chills (if infection is present)
If these symptoms persist or intensify, timely evaluation is crucial to prevent kidney damage or infection.
Diagnosing Urinary Stones at THANC Hospital
At Thanc Hospital, Chennai, we follow a comprehensive, evidence-based diagnostic protocol to determine stone size, location, and impact on kidney function.
1. Clinical Evaluation
A detailed consultation helps assess pain pattern, urinary symptoms, fluid habits, and past stone history.
2. Imaging Studies
- Ultrasound (USG) — quick, non-invasive screening for stones and hydronephrosis.
- CT KUB (Kidney-Ureter-Bladder) Scan — gold standard for accurate stone localization and measurement.
- X-ray KUB — used in selected cases for radiopaque stones.
3. Urine and Blood Tests
- Urine analysis for infection, crystals, and pH.
- Serum creatinine and electrolytes to check kidney function.
- 24-hour urine test (in recurrent cases) to identify metabolic causes.
Based on results, our urology team customizes the best treatment approach — medical or surgical.
What Is Ureteroscopy (URS)?
Ureteroscopy (URS) is a minimally invasive, endoscopic procedure used to locate and remove stones from the ureter or kidney using a thin, flexible instrument called a ureteroscope.
At Thanc Hospital, this procedure is often combined with Laser Lithotripsy, where a laser precisely breaks stones into fine fragments that can be easily removed or passed naturally.
There are two main types:
- Rigid URS: for lower and mid-ureteral stones.
- Flexible URS: for upper ureter or kidney stones (Retrograde Intrarenal Surgery – RIRS).
This technique avoids external cuts, minimizes pain, and ensures faster recovery.
Ureteroscopy & Laser Lithotripsy Procedure: Step-by-Step
Here’s what you can expect during your stone removal journey.
Preoperative Preparation
Days before surgery:
- Complete blood tests, urine analysis, and ECG / chest X-ray if required.
- Stop specific medications (like blood thinners) as advised.
- Maintain adequate hydration.
- Detailed counseling about anesthesia and recovery expectations.
Our urologists and anesthesiologists ensure every patient is medically optimized before the procedure.
The procedure is supported by our expert Anesthesia & Critical Care team, ensuring complete safety, comfort, and smooth recovery throughout the surgical process.
On the Day of Surgery
Ureteroscopy with Laser Lithotripsy is usually a day-care or short-stay procedure (discharge within 24–48 hours).
In the Operating Room:
- Administration of anesthesia (general or spinal).
- Insertion of ureteroscope via the natural urinary passage (no external cuts).
- Stone visualization using an HD camera.
- Laser fragmentation using a Holmium:YAG laser.
- Extraction of fragments with micro-baskets or spontaneous passage.
- Placement of a temporary stent (in some cases) to ensure smooth urine flow.
Duration: 45–90 minutes, depending on stone size and location.
Postoperative Care and Monitoring
After the procedure, patients are shifted to the recovery unit for observation.
Our nursing team monitors:
- Urine output and color
- Pain or discomfort
- Vital signs and hydration
Most patients can resume oral intake within a few hours and are discharged the same or next day with medications and care instructions.
Recovery at Home: Week-by-Week Guide
Days 1–3: Early Recovery
- Mild burning while urinating and slight blood-tinged urine are normal.
- Drink plenty of fluids (2–3 liters/day) to flush out residual fragments.
- Take painkillers and antibiotics as prescribed.
- Avoid heavy lifting or strenuous activity.
Days 4–7: Steady Improvement
- Pain subsides; urine becomes clearer.
- Resume light work or routine activities.
- Continue hydration and medications.
Weeks 2–3: Full Recovery
- Normal energy and comfort return.
- Stent (if placed) is usually removed after 10–14 days.
- Follow-up ultrasound confirms stone clearance.

Frequently Asked Questions (FAQ)
Is Ureteroscopy painful?
No. The procedure is done under anesthesia. Mild discomfort after surgery is manageable with pain medication.
How soon can I return to work?
Most patients resume normal activities within 3–5 days, depending on recovery and stent status.
What is the purpose of a stent?
A ureteral stent maintains urine flow and prevents swelling-related blockage after stone removal. It’s temporary and removed after 10–14 days.
Can stones recur after removal?
Yes, if risk factors persist. Regular hydration and dietary modifications greatly reduce recurrence.
Will I need open surgery?
Open surgery is rarely needed today. Over 95% of stones are successfully treated with URS or laser lithotripsy.
Is hospitalization necessary?
Usually, no. Most patients go home within 24 hours.
