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.
Urethral Stricture Disease. The urethra is a tube that carries urine from your bladder out of your body. A urethral stricture occurs when scar tissue in or around your urethra limits or blocks the flow of urine. Inflammation, an injury or an infection can create this scar tissue. Urethral stricture disease is more common in men, but women can develop it, too.
