Retro intra-renal surgery (RIRS)


Retro intra-renal surgery (RIRS), a procedure which allows doctors to perform surgery inside the kidney without making an incision. This technique is carried out by using a viewing tube called a fiber optic endoscope.

RIRS is done to remove the stone by using a scope. The stone is seen through the scope which is placed through the urinary opening into the bladder and then through the ureter into the kidney. The scope is then moved up the urinary tract to a position where the stone is crushed by laser or an ultrasound probe or grabbed by small forceps.

 RIRS is used for difficult to treat cases such as:

* Stones too large for ESWL
* Failed previous treatments
* Patients with bleeding disorders and obesity
* Strictures and Tumors

 There are many advantages of this technique over open surgery as it provides:

* Quicker solution to the problem
* Reduces the prolonged pain after the surgery
* Deeper incision
* Fewer traumas
* Much faster recovery

 RIRS is performed by a specialist, a urologist with special expertise in RIRS. The procedure is usually done under general or spinal anesthesia.
