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.
The urethra's main job in males and females is to pass urine outside the body. This thin tube also has an important role in ejaculation for men. When a scar from swelling, injury or infection blocks or slows the flow of urine in this tube, it is called a urethral stricture. Some people feel pain with a urethral stricture. The bladder empties through the urethra and out of the body (called voiding). The female urethra is much shorter than the male's.
