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 is a medical condition that mainly affects men. According to the National Institutes of Health (NIH), very few women get urethral strictures. In addition, very few individuals are born with this condition (NIH) . Urethral stricture occurs specifically in the urethra. The urethra is a tube that carries urine from the bladder so it can be expelled from the body. In healthy males, the urethra is wide enough for urine to flow freely through it. When the urethra narrows, it is known as a urethral stricture. Urinary flow can be slightly or severely restricted.
