A minimally invasive endoscopic procedure that allows a very narrow and flexible instrument, which carries a camera, to be inserted through the urethra and up to the kidney, allowing kidney stones to be pulverized and extracted.
Retrograde Intrarenal Surgery (RIRS stands for RIRS) is a minimally invasive endoscopic surgical procedure that allows the removal of stones, also called kidney stones, using an instrument called a flexible ureteroscope that has a high-definition camera incorporated at its tip and through which a laser fiber can be introduced, with which the lithiasis can be fragmented and pulverized (calculation) extracting small fragments if necessary for chemical analysis.
The procedure is performed under anesthesia, and the patient can usually go home within 24 hours, the next day, or even the same day. It leaves no incisions or external wounds, as it is performed through the urethra and ascends the urinary tract.
This procedure can also be used diagnostically or therapeutically for the conservative treatment of urothelial tumors of the upper urinary tract.
