Retrograde Intrarenal Surgery (RIRS)

Retrograde Intrarenal Surgery (RIRS) is a surgical procedure performed within the kidney using a viewing tube known as a fiberoptic endoscope.

In this procedure, the endoscope is placed via the urethra into the bladder and then passed through the ureter into the part of the kidney where the urine gets collected. In this way, the endoscope is moved up the urinary tract system to a specific position within the kidney.

RIRS is generally performed to remove a stone or a small tumor. The stone can be directly visualized through the endoscope and it can then be fragmented using an ultrasound probe, evaporated with the help a laser probe or grabbed using small forceps. RIRS, an outpatient procedure, is typically performed under general or spinal anesthesia.

Advantages of RIRS

Some of the major advantages of RIRS over open surgery include a speedier solution of the problem, the removal of prolonged pain following the surgery, and faster recovery.

RIRS is recommended for patients who are suffering from kidney stones or in certain cases such as narrowing of the kidney outlet or strictures and tumors in the kidney.

RIRS is mainly used for treating certain difficult conditions such as:

  • Previous treatment attempts which have completely failed
  • Large stones which cannot be removed using ESWL
  • Strictures or tumors
  • Stones in children
  • Patients suffering from bleeding disorders
  • Patients suffering from gross obesity
