Retrograde Intrarenal Surgery (RIRS)
Retrograde intrarenal surgery (RIRS) is a surgical procedure performed on the kidney using a viewing tube called a fibreoptic endoscope. Through this device, a laser fibre (Holmium laser) is used to treat kidney stones.
How and why is it done?
RIRS is performed to remove stones without making any incisions on the kidney while using a laser and a viewing tube called a fiberoptic endoscope that goes through the urethra into the kidney. It is performed under general, local, or spinal anaesthesia. This surgery can take around 1 to 2 hours. This surgery is required for patients that have kidney stones measuring 1.5cm in diameter.
RIRS is done to remove a stone. The stone is seen through the scope and can then be manipulated or crushed by an ultrasound probe or evaporated by a laser probe or grabbed by small forceps, etc.

Frequently Asked Questions
Is RIRS a Ureteroscopy?
Retrograde intrarenal surgery (RIRS) refers to the surgical management of upper urinary tract pathologies with a retrograde ureteroscopic approach. With the development of new surgical instruments, the deflection mechanism, visuality, and durability of RIRS have improved.
What is the difference between RIRS and URS?
The success of URS was defined as stone-free status after the single procedure while RIRS success rate was considered as the presence of residual stone fragments smaller than 4 mm at the first procedure.
Which is better PCNL or RIRS?
RIRS is more advantageous in terms of fluoroscopy time, fall in haemoglobin, VAS, analgesic use, and hospital stay, while PCNL (Percutaneous Nephrolithotomy - PCNL is a technique used to remove certain stones in the kidney or upper ureter) is better in terms of surgery duration.
