Retrograde intrarenal surgery (RIRS) is a procedure for doing surgery within the kidney by accessing the kidney from the natural urinary passage.In this procedure, a flexible telescope is used to access each part of the kidney from within. With the help of Holmium laser, the stones are broken into fine particles and removed.
This procedure is preferably done under general anaesthesia.
Preoperative Intravenous Urogram(IVU) is done to check the location of the stone and confirm the functioning of the kidney. Other blood tests and work up to assess fitness for operation are done preoperatively.
