The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on laparoscopic deroofing of simple renal cysts.


Solitary cysts in the kidney are common, but rarely cause any symptoms. Multiple cysts are less common and are usually due to polycystic kidney disease, which is an inherited condition. Laparoscopic deroofing involves draining the cyst and removing part of the cyst wall, which is done through small cuts in the abdomen using a fine telescope to see inside the body ('keyhole surgery').
