Procedure overview
What is Retrograde Intrarenal Surgery (RIRS)?
During RIRS, the scope travels through the urethra, bladder and ureter to the urine-collecting part of the kidney. Stones can then be fragmented with a laser and small pieces retrieved when appropriate.
Important. This page provides general education. Your diagnosis, treatment choice and recovery plan must be confirmed in consultation.
When it may be considered
Clinical needs come before technique.
- 01Kidney stones unsuitable for simple observation
- 02Previous unsuccessful stone treatment
- 03Selected patients with bleeding risk or obesity
- 04Stones in locations that need flexible endoscopic access
Diagnosis & preparation
What happens before a decision.
Assessment may include
- A focused history and physical examination
- Urine and blood tests relevant to the condition
- Ultrasound, X-ray, CT, MRI or other appropriate imaging
- Anaesthesia and general-health assessment when surgery is planned
Specific tests vary. Bring existing reports so unnecessary repetition can be avoided where possible.
Potential benefits
Why this option may be discussed.
No external kidney incision
Access to difficult areas within the kidney
Laser fragmentation under direct vision
Often supports a shorter recovery than open surgery
All procedures have potential risks and may not achieve the same result for every patient. Alternatives, risks and expected outcomes should be discussed personally.
Recovery & follow-up
Plan the return to everyday life.
A temporary ureteric stent may be recommended. Mild discomfort can occur after the procedure. Hydration, prescribed medicines and scheduled follow-up help monitor healing and stone clearance.
Contact your care team urgently if advised warning signs occur
These may include fever, worsening pain, heavy bleeding, breathing difficulty or inability to pass urine. Follow the discharge instructions given to you.
