The invasive nature of conventional voiding pressure measurement limits routine diagnostic use for men with LUTS and has encouraged research into non-invasive methods of categorising obstruction. We have developed a technique to measure isovolumetric bladder pressure non-invasively, the penile cuff test, which is well tolerated and quick to perform. When combined with flow rate, a sufficiently accurate diagnosis of BOO is made to enable improved prediction of outcome from TTURP for most men tested. In addition, release of penile compression allows derivation of the penile compression/release index, which is also useful for categorisation of detrusor function during voiding.
