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.
What is urethral prolapse? The urethra is the tube that drains urine from the bladder to the outside of the body. Urethral prolapse occurs when the inner lining of the urethra sticks out. When this happens, the opening of the urethra looks like a small pink donut and seems larger than normal.
