- RETROGRADE INT4RARENAL SURGERY (RIRS)
- It is called retrograde intrarenal surgery (RIRS) and it is, indeed, a procedure for doing surgery within the kidney using a viewing tube called a fiberoptic scope (an endoscope). In RIRS the scope is placed through the urethre (the urinary opening) into the bladder and then through the ureter into the urine-collecting part of the kidney. The scope thus is moved retrograde (up the urinary tract system) to within the kidney (intrarenal).
- Retrograde Intrarenal Surgery (RIRS) allows the surgeon to do surgery inside kidney without making the an incision. The instrument for RIRS enters through the body's natural opening, through the bladder and the ureter, info the kidney.
- When is RIRS used
The Minimally invasive Urology Program specializes in using RIRS for difficult-to-treat cases, cases, such as :
- Stones too large for ESWL (lithotripsy)
- Failed previous treatment attempts
- Stones in children
- Patients with bleeding disorders
- Patients with gross obesity
A combination of RIRS and ESWL a unique treatment option on offer. In allows a wider range of kidney problems to be treated using minimally invasive procedures.
Indications of RIRS for renal stones are
- Failed Extracorporeal shockwave are
- Radiolucent stones
- Concomitant uretereic and renal stones
- Anatomical problems e.g. infundibular stenosis
- Bleeding disorders
- Advantage of RIRS:
- a quicker solution of the problem ,
- elimination of prolonged pain after surgery,
- less trauma
- faster recover.
