Arterial access from lower extremity. The common femoral artery is the only access site used in the lower extremity. Catheters used for performing coronary angiography via the femoral artery were developed by Melvin Judkins, MD; thus, the method often is referred to as the Judkins technique. This widely used method requires separate preformed catheters for the right and left coronary arteries (see the images below).
Urethral sounds/play, sometimes called sounding, is basically inserting objects (often steel sounds and catheters) into the urethra for erotic purposes. Sounds painful and unpleasant to most, but some people get a kick out of this.
HOME CLINIC; WHEN THE WATER PIPES MAKE THOSE WEIRD NOISES. WATER pipes that bang, hammer or squeal are not only a nuisance, they may also be an indication of plumbing problems. One of the most common noises is a whistling that occurs when a water valve or faucet is turned on, or when a toilet tank is refilling after flushing.
