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.
A urethral stricture is scarring in or around the urethra that narrows or blocks the passageway through which urine flows from the bladder. The stricture results from inflammation, infection or injury, and is much more common in men than in women. The scarring can occur anywhere between the bladder and the tip of the penis.
