RIRS (retrograde intrarenal surgery): Retrograde intrarenal surgery (RIRS) is a procedure for doing surgery within the kidney using a viewing tube called a fiberoptic endoscope. In RIRS the scope is placed through the urethra (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).RIRS may be done to remove a kidney stone. The kidney stone is seen through the scope and can then be manipulated or crushed by an ultrasound probe or evaporated by a laser probe or grabbed by small forceps.

The stone is seen through the scope and can then be manipulated or crushed by an ultrasound probe or evaporated by a laser probe or grabbed by small forceps, etc.RIRS is performed by a specialist, a Urologist (endourologist) with special expertise in RIRS. The procedure is usually done under general or spinal anesthesia. The advantages of RIRS over open surgery include a quicker solution to the problem, the elimination of prolonged pain after surgery, and much faster recovery. Retrograde intrarenal surgery (RIRS) is a procedure that is performed to treat kidney stones using a narrow fiber-optic tube with a camera and light source called an endoscope. The endoscope is threaded to the kidneys through the natural opening of the urethra (the tube that passes urine out of the body). The endoscope helps your doctor to view the stones in the kidney. Other instruments can be inserted through the endoscope to destroy the stones. The stones can be removed with forceps, evaporated with a laser probe, or crushed and removed using an ultrasound probe.

A transurethral resection of the prostate (TURP) is a surgical procedure that involves cutting away a section of the prostate. The prostate is a small gland in the pelvis only found in men. It's located between the penis and bladder, and surrounds the urethra (the tube that carries urine from the bladder to the penis).
