Retrograde Intra Renal Surgery (RIRS) is a minimally invasive endoscopic procedure used to diagnose and treat conditions affecting the kidney and upper urinary tract. During this procedure, a thin, flexible endoscope is passed through the urethra and bladder, then up through the ureter to reach the kidney. This approach allows direct visualisation of the kidney’s internal structures without requiring any external incisions.
RIRS primarily addresses kidney stones, particularly those located in difficult-to-reach areas of the kidney or those that may not have responded to other treatments such as shock wave lithotripsy. The procedure enables urologists to fragment stones using laser energy and remove the pieces, or to perform biopsies and treat other kidney abnormalities. The ureteroscope’s flexibility allows access to virtually all parts of the kidney’s collecting system, enabling treatment of multiple stones in different locations during a single procedure.
The procedure can provide both diagnostic and therapeutic benefits. While examining the kidney’s interior, urologists may be able to address identified problems, potentially reducing the need for multiple procedures in some cases.
