When is surgery needed for kidney stones?
Not all kidney stones require surgery. However, intervention is indicated when:
- Stone size >6‑7mm (low chance of spontaneous passage).
- Stone causing persistent pain, obstruction, or hydronephrosis.
- Stone associated with fever or infection (emergency).
- Stone in a solitary kidney or causing kidney function decline.
- Failed medical expulsion therapy after 4‑6 weeks.
- Patient preference for definitive treatment.
At Vivekananda Hospital, we offer a full range of minimally invasive stone surgeries. The choice depends on stone size, location, composition, and your anatomy.
Complete comparison of all stone procedures
Here is a side‑by‑side comparison of the five main surgical options:
| Procedure | Best stone size | Incisions | Anaesthesia | Stone‑free rate (1 session) | Recovery time (desk job) | Cost (India) |
|---|---|---|---|---|---|---|
| URS (Ureteroscopy) | 5‑15mm (ureter) | None (via urethra) | Spinal/General | 90‑98% | 2‑3 days | ₹45,000‑70,000 |
| RIRS (Flexible URS) | 5‑20mm (kidney) | None | General | 85‑90% | 2‑4 days | ₹60,000‑90,000 |
| PCNL | >15‑20mm, staghorn | 1cm back incision | General | 95‑98% | 5‑7 days | ₹55,000‑85,000 |
| ESWL | <15mm (upper ureter/kidney) | None | Sedation | 50‑70% | 1‑2 days | ₹25,000‑40,000 |
| Open surgery | Any (rare today) | Large flank incision | General | >95% | 4‑6 weeks | ₹50,000‑80,000 |
URS (Ureteroscopy) – for ureteral stones
Ureteroscopy is the gold standard for stones lodged in the ureter (the tube from kidney to bladder). A thin semi‑rigid or flexible scope is passed through the urethra, bladder, and up into the ureter. A holmium laser fragments the stone into dust or small pieces. No incisions.
Indications: Ureteral stones 5‑15mm, especially lower ureter stones where ESWL is less effective.
Success rate: 95‑98% for stones <15mm.
Recovery: Most patients go home the same day. A stent is often placed for 7‑14 days.
Cost at Vivekananda Hospital: ₹45,000‑70,000.
RIRS – for kidney stones up to 20mm
RIRS (Retrograde Intrarenal Surgery) uses a flexible ureteroscope that can bend 270 degrees to reach stones inside the kidney. It is ideal for stones in the renal pelvis or calyces, including lower pole stones.
Indications: Kidney stones 5‑20mm, especially lower pole or in patients with bleeding disorders.
Success rate: 85‑90% for stones <15mm; 75‑80% for 15‑20mm.
Recovery: Same‑day or next‑day discharge. Stent placed in most cases.
Cost at Vivekananda Hospital: ₹60,000‑90,000.
PCNL – for large or complex stones
PCNL (Percutaneous Nephrolithotomy) is the most effective procedure for large stones (>15‑20mm), staghorn calculi, or stones that have failed RIRS. A 1cm incision is made in the back, and a nephroscope is passed directly into the kidney. The stone is fragmented with laser or ultrasound and suctioned out.
Indications: Stones >15mm, staghorn stones, lower pole stones >15mm.
Success rate: 95‑98% in one session.
Recovery: Hospital stay 2‑3 days. Return to desk work in 1 week.
Cost at Vivekananda Hospital: ₹55,000‑85,000.
ESWL – non‑invasive option
ESWL (Extracorporeal Shock Wave Lithotripsy) uses focused shock waves from outside the body to break stones. It is non‑invasive but has lower success rates, especially for larger or dense stones.
Indications: Stones <15mm in the upper ureter or renal pelvis, with favourable density (<900 HU). Not for lower ureter stones.
Success rate: 50‑70% after one session; often needs repeat.
Recovery: Outpatient, back to work next day.
Cost at Vivekananda Hospital: ₹25,000‑40,000.
Cost comparison in India (2026)
Costs vary by hospital, city, and insurance coverage. Below are approximate ranges at Vivekananda Hospital, Hyderabad (includes surgeon fee, anaesthesia, OT, 1‑2 days stay where applicable):
- ESWL: ₹25,000 – ₹40,000
- URS with laser: ₹45,000 – ₹70,000
- PCNL: ₹55,000 – ₹85,000
- RIRS (flexible ureteroscopy): ₹60,000 – ₹90,000
- Open surgery (rare): ₹50,000 – ₹80,000
Most health insurance policies cover stone surgery. Cashless facility available at Vivekananda Hospital.
Interactive FAQ – Kidney stone operation
There is no single “best” – it depends on stone size, location, and your health. For ureteral stones, URS is best. For kidney stones <15mm, RIRS is excellent. For large stones >15mm, PCNL has the highest success rate.
The surgery itself is painless under anaesthesia. Afterward, URS and RIRS cause mild stent discomfort (urgency, flank pain). PCNL causes some incisional pain. Most patients rate post‑op pain as 2‑4/10, manageable with oral painkillers.
URS/RIRS: back to desk work in 2‑4 days. PCNL: 1 week. ESWL: 1‑2 days. Full physical activity takes 2‑4 weeks for URS/PCNL, 1 week for ESWL.
Yes, but ESWL has lower success (50‑70% vs 95% for URS) and may require multiple sessions. For lower ureter stones, ESWL is not recommended. Discuss with your urologist.
RIRS (flexible ureteroscopy) is typically the most expensive due to the disposable scope cost. PCNL is slightly less. ESWL is the cheapest.
Not always. URS and RIRS often require a stent for 7‑14 days, but some uncomplicated cases do not. PCNL may or may not. ESWL never requires a stent.
95‑98% stone‑free after one session. It is the gold standard for stones that size.
Yes, but you will need to stop blood thinners (aspirin, warfarin, clopidogrel) 5‑7 days before surgery, after consulting your cardiologist. URS and PCNL are safer than ESWL in this setting.
Rarely – less than 1% of cases. It is reserved for very large staghorn stones that cannot be treated with PCNL, or for patients with abnormal anatomy.
Disclaimer: The choice of kidney stone operation should be made with your urologist based on imaging and your health status. At Vivekananda Hospital, we offer all modern minimally invasive options.
