Kidney stones are one of the most common reasons people visit a urologist — and one of the most painful. The good news is that modern treatment options have come a long way. In most cases, large incisions are no longer necessary. At Prime Hospital, Ramgarh, we offer a comprehensive stone programme — “Stones Anywhere, Any Size” — covering every technique from non-invasive shock-wave therapy to minimally invasive keyhole surgery.
Here is a plain-language guide to the four main treatments and how your doctor decides which one is right for you.
Why Treatment Depends on the Stone
Not all kidney stones are the same. Size, location, composition, and whether the stone is causing a blockage all influence the choice of treatment. A 4 mm stone in the ureter will be managed very differently from a 3 cm staghorn stone filling the entire kidney pelvis.
1. ESWL — Extracorporeal Shock Wave Lithotripsy
ESWL is the most non-invasive option. A machine outside your body sends focused shock waves through your skin to break the stone into small fragments that pass out naturally in your urine. No cuts, no anaesthesia in most cases.
Best for: Stones up to about 2 cm in the kidney or upper ureter, in patients who are not pregnant and do not have a blockage downstream.
What to expect: The procedure takes 45–60 minutes. You may need more than one session. Some mild bruising or blood in the urine for a day or two is normal.
2. URSL — Ureteroscopy with Laser Lithotripsy
A thin flexible telescope (ureteroscope) is passed through the urethra and bladder up into the ureter or kidney. No cuts are made in the skin. A laser fibre is then used to break the stone into fine dust.
Best for: Stones in the ureter at any level, and smaller stones inside the kidney (under 1.5–2 cm). Very effective for stones that ESWL has already tried to break but could not.
What to expect: Performed under spinal or general anaesthesia. Most patients go home the same day or next morning. A temporary ureteral stent may be placed for a few days to help healing.
3. RIRS — Retrograde Intrarenal Surgery
RIRS uses a very thin, flexible ureteroscope that bends and turns to reach stones deep inside the kidney — places a rigid scope simply cannot access. Combined with laser energy, even stones in difficult locations can be pulverised and removed.
Best for: Stones 1–2.5 cm inside the kidney, multiple small stones, or stones in complex kidney anatomy such as a horseshoe kidney.
What to expect: Very similar recovery to URSL — often a day-care or overnight stay. Because no skin puncture is made, patients recover faster than with PCNL.
4. PCNL — Percutaneous Nephrolithotomy
PCNL is the most powerful option — used for large or very hard stones. A small (1 cm) puncture is made through the skin into the kidney under X-ray or ultrasound guidance. A nephroscope is then used to directly visualise and remove the stone fragments.
Best for: Large stones (over 2 cm), staghorn calculi, or stones that have not responded to other treatments.
What to expect: Performed under general or spinal anaesthesia. Hospital stay of 2–3 days is typical. A nephrostomy tube may be placed temporarily to drain the kidney.
Which Treatment Will My Doctor Choose?
Your urologist will look at your CT scan or X-ray, measure the stone, check its position, and assess your general health before recommending a treatment. Often a combination approach is used — for example, ESWL first for a moderate stone, followed by URSL if fragments remain.
At Prime Hospital, Ramgarh
Our urology team performs all four procedures — ESWL, URSL, RIRS, and PCNL — under one roof. We also have 24×7 pathology, in-house blood bank, and a 10-bed ICU for post-operative care if needed. Most stone procedures are covered under Ayushman Bharat (PMJAY), CGHS, and major TPA insurance policies.
If you are passing a stone, experiencing severe flank pain, or have been told you need surgery, call us on +91 94303-92033 (24×7). Our urologist will review your scans and guide you on the best path forward.
