Retrograde Intrarenal Surgery (RIRS)

Retrograde Intrarenal Surgery (RIRS) allows the surgeon to do surgery inside the kidney without making an incision. The instrument for RIRS enters through the body's natural opening, through the bladder and the ureter, into the kidney.

RIRS is used for patients with stones in the kidney, narrowing of the outlet of the kidney or within the kidney (strictures) and tumors in the kidney. The RIRS is an outpatient procedure using local, intravenous or general anesthesia.

The Minimally Invasive Urology Institute specializes in using RIRS for difficult-to-treat cases, such as:

  • Failed previous treatment attempts
  • Stones too large for ESWL (lithotripsy)
  • Strictures
  • Tumors
  • Stones in children
  • Patients with bleeding disorders
  • Patients with gross obesity

This procedure is done with flexible ureteroscopy and Laser.
