A means of measuring bladder pressures during urination, in which urinary flow is interrupted by inflating a pediatric blood pressure cuff placed around the penis. The cuff pressure at which urinary flow stops is an indirect, noninvasive measure of bladder pressure during urination. The test is used to distinguish the causes of urinary hesitancy: men with prostatic hyperplasia have high bladder pressures when they urinate, whereas men with bladder weakness do not.
