Endoscopic Kidney Stone Removal: The Complete Patient Guide (2026)

What is endoscopic kidney stone removal? (URS and RIRS explained)

Endoscopic kidney stone removal refers to two closely related procedures: Ureteroscopy (URS) for stones in the ureter, and Retrograde Intrarenal Surgery (RIRS) for stones inside the kidney. Both use a thin, flexible scope (about 3mm diameter) inserted through the urethra – no skin incisions. The surgeon either extracts the stone with a tiny basket or breaks it into dust using a holmium laser. This is the gold standard for stones 5mm to 20mm that are not responding to conservative management.

The procedure is performed under spinal or general anaesthesia and typically takes 30–90 minutes. Most patients go home the same day or after one overnight stay.

Exactly who needs this procedure? (Stone size & location chart)

Stone location	Size	Recommended treatment	Why endoscopy?
Lower ureter (near bladder)	5–10 mm	URS with basket	Highest success rate (95%+)
Mid/upper ureter	6–15 mm	URS with laser	ESWL often fails here
Kidney (renal pelvis or calyx)	10–20 mm	RIRS with laser	Avoids PCNL puncture
Any location	>20 mm	PCNL first choice	Endoscopy possible but may need multiple sessions
Any location	<5 mm	Medical expulsion therapy first	Endoscopy only if pain/infection

Step‑by‑step surgical walkthrough (what happens inside the OT)

1. Pre‑operative preparation: You will be asked to fast for 6 hours. A urine test confirms no active infection.
2. Anaesthesia: Spinal anaesthesia (numb from waist down) or general anaesthesia. You feel nothing.
3. Urethral access: The surgeon gently inserts the ureteroscope through the urethra into the bladder.
4. Ureteral navigation: A thin guidewire is passed up the ureter. The scope follows the wire.
5. Stone visualisation: High‑definition camera shows the stone’s exact position, shape, and hardness.
6. Laser fragmentation (if needed): A 200‑micron holmium laser fibre breaks the stone into tiny pieces (<1mm).
7. Extraction: Smaller fragments are removed with a nitinol basket. Dust is left to pass in urine.
8. Stent placement: A double‑J stent (thin tube from kidney to bladder) is placed if the ureter is swollen or to prevent fragment obstruction. It stays for 7–14 days.
9. Recovery room: You are monitored for 1–2 hours. Most patients drink fluids and walk within 6 hours.

Day‑by‑day recovery diary (what actually happens)

Day	Symptoms	Allowed activities	Pro tips
Day 0 (surgery day)	Groggy, mild burning with first urination, pink urine	Bed rest; sips of water	Use a bedpan if spinal anaesthesia hasn't worn off
Day 1	Mild flank pain (stent), frequency/urgency, blood streaks	Walk around house; shower OK	Drink 2 litres water; take prescribed tamsulosin
Day 2–3	Pain decreases, but stent causes urgency and occasional flank twinge	Return to desk work (remote or office)	Avoid heavy lifting (>5 kg)
Day 4–7	Urine clears. Stent awareness: you feel it when you bend or empty bladder	Light exercise (walking, stretching)	Use heating pad for flank discomfort
Day 8–14	Stent removal (clinic procedure – 1 minute). Relief is immediate	Normal non‑contact activities	After stent removal, you may have mild back pain for 1 day
Week 3–4	Complete recovery. No restrictions	Full exercise, swimming, sex	Continue high fluid intake to prevent new stones

Risks and complications – real numbers from 2025 meta‑analysis

• Urinary tract infection: 2‑5% – treated with oral antibiotics.
• Ureteral injury (perforation): <1% – usually heals with stent placement.
• Residual fragments >2mm: 5‑10% for stones >15mm – may need second look.
• Stent discomfort (frequency, urgency, flank pain): 70% – temporary, resolves after removal.
• Stricture (narrowing of ureter): 0.5% – rare, treatable with balloon dilation.

URS vs ESWL vs PCNL vs open surgery – which is best for you?

Procedure	Incisions	Stone size limit	Success rate	Recovery time	Best for
URS / RIRS	None (via urethra)	Up to 20mm	90‑95%	3‑7 days	Ureteral stones, lower pole stones
ESWL (shock wave)	None	<15mm	70‑85%	1‑2 days	Small kidney stones, non‑hard density
PCNL	1cm back incision	>20mm or staghorn	95%	1‑2 weeks	Large or complex kidney stones
Open surgery	Large flank incision	Any	98%	4‑6 weeks	Only for failed endoscopy/anatomical abnormalities

How to prepare for endoscopic kidney stone removal (pre‑op checklist)

• 1 week before: Stop blood thinners (aspirin, clopidogrel, warfarin) after consulting your cardiologist.
• 48 hours before: Urine culture to rule out infection. If positive, antibiotics will be started.
• Night before: Light dinner. No solid food after midnight. Clear fluids allowed up to 2 hours before surgery.
• Day of surgery: Arrive 2 hours early. Bring all medical records, insurance card, and a family member.
• What to pack: Loose clothes, slippers, phone charger, a book (you will be awake most of the day).

Life after stent removal – long‑term stone prevention

Having one stone puts you at 50% risk of another within 5 years. Endoscopy removes the stone but does not change your metabolism. Follow these proven prevention steps:

• Drink 2.5–3 litres of water daily (aim for clear or pale yellow urine).
• Reduce dietary oxalate: limit spinach, nuts, tea, chocolate.
• Normal calcium intake (do not restrict – dietary calcium binds oxalate in the gut).
• Limit sodium to <2,300 mg/day (salt increases urinary calcium).
• If you had calcium oxalate stones, your doctor may prescribe thiazide diuretics or potassium citrate.
• Get a 24‑hour urine test at 3 months post‑op to tailor prevention.
