Retrograde Intrarenal Surgery (RIRS) is a popular procedure performed by an endourologist if the patient suffers from kidney stones. In contrast to the cuts or extrarenal shock methods, the RIRS allows physicians to address the kidney using a urinary system. The surgeon can navigate a flexible ureteroscope to identify the stone and then remove it, or further fragment it to allow it to pass through the ureter with less destruction of the tissues which fastens the RIRS surgery recovery time.
