What is the Full Form of RIRS in Medical?

The Full Form of RIRS in Medical term is Retrograde Intrarenal Surgery. Utilizing a flexible ureterorenoscopy, retrograde intrarenal surgery provides a technique used to treat upper urinary system malignancies and gain access to tiny kidney stones. The procedure uses a laser & a viewing tube called a fibreoptic endoscope that passes through the urethra and into the kidney without making an incision on the kidney. Under local, spinal, or general anaesthesia, it is carried out. Using an ultrasound probe, the doctor can visualize the stone and smash it, allowing the stones to be removed.

Process of RIRS:

• A narrow, fiber-optic device called a flexible ureteroscope is used by the surgeon to pass into the urinary tract and reach the kidney.
• After locating the stone, it is shown on a screen and broken up into smaller pieces using specialized instruments.
• The smaller pieces are either allowed to naturally flow along the urinary tract or are extracted using a basket-like device.

Cons of RIRS:

• For stones measuring 2 cm or less, RIRS works best; larger stones might need more than one session.
• The use of devices inside the ureter is uncommon, yet it can infrequently result in strictures or damage.
• Some little pieces might stay inside the kidney and need to be treated further or pass through on their own.
