Definition : Instruments designed to measure the functional length andor to dilate and measure the lumen of the urethra. These devices are typically manual, handheld instruments consisting of a set of cylindrical (e.g., metallic, plastic) urethral dilators of several sizes and a mechanism that displays the diameter and/or degree of dilation (i.e., expansion) of the urethral conduit on a dial. Instruments intended to measure the functional length of the urethra (urethral profile) are also available. Urethrometers are intended to measure the urethra during procedures such as urethral stricture dilation and urethral abnormality studies.
