The urethra is measured with a tool called a Urethra Gauge.
SI Unit of Measurement:
SI unit of Measurement is the most widely accepted means for measurement.
The inner circumference of the urethra can range is size from 2 millimeters to 50 millimeter's.
French Unit of Measurement:
A frequently used system of measurement has been the French Unit of measure which has been around since the 1400's. This unit of measure allows for a fast rough measurement, should not be used for precise measurement.
Most of the Catheters stocked in hospitals are:
[6Fr, 8Fr, 10Fr, 12Fr, 14Fr, 16Fr, 18Fr, 20Fr, 22Fr, 24Fr, 26Fr, 28Fr, 30Fr, 32Fr, 34Fr, 36Fr, 38Fr, 40Fr, 42Fr].
Example:
A person that has a circumferential measurement of the urethra of 9Fr finds themselves in a predicament because most hospitals only stock their hospitals with even sizes, thus the size of catheter available is either an 8 Fr or a 10Fr. Herein lies a potential problem in the availability of necessary equipment for the health care provider.
