Tim Idzenga came up with the idea of using the sound produced by the urinary flow in the urethra as a measure of the urethral resistance. He performed the measurement by placing a microphone against the perineum, between the scrotum and anus. The frequency spectrum of the sound was found to correlate with the narrowing of the urethra. The degree of narrowing can therefore be determined from the recorded urinary sound.
A patent for this invention is being applied for in cooperation with the company IQ+ Medical BV.
So reports Science Daily on April 24, 2008. A 2005 study by Idzenga and colleagues tells of an early version of the work.
(Thanks to investigator Jilly Dybka for bringing this to our attention.)
