The invasive nature of conventional cystometry has encouraged the development of alternative urodynamic techniques that do not require bladder catheterisation. Most non-invasive methods rely on flow interruption during voiding to allow an estimate of isovolumetric bladder pressure. The currently available methods include mechanical interruption at the external meatus using a condom catheter, interruption at the level of the penile urethra using an inflatable cuff and manual compression and release of the penile urethra during voiding. All of these measures seek to differentiate between the urodynamic diagnoses of bladder outlet obstruction (BOO), detrusor hypocontractility (DH) and detrusor overactivity (DO). The present study aimed to validate the penile compression-release manoeuvre described by Sullivan and Yalla (2000) by repeating their study using mechanical interruption of flow with a penile cuff rather than manual compression.
