The penile cuff test: A clinically useful non-invasive urodynamic investigation to diagnose men with lower urinary tract symptoms.
OBJECTIVE
To summarize the development of a novel non-invasive test to categorize voiding dysfunction in men complaining of lower urinary tract symptoms (LUTS) - the penile cuff test.


METHODS
The test involves the controlled inflation of a penile cuff during micturition to interrupt voiding and hence estimate isovolumetric bladder pressure (p(ves.isv)). The validity, reliability, and clinical usefulness of the test were determined in a number of studies in men with LUTS.


RESULTS
The penile cuff test can be successfully performed in over 90% of men with LUTS. The reading of cuff pressure at flow interruption (p(cuff.int)) gives a valid and reliable estimate of invasively-measured p(ves.isv) and when combined with the reading for maximum flow rate obtained during the test (Q(max)) produces an accurate categorization of bladder outlet obstruction (BOO). Use of this categorization prior to treatment allows improved prediction of outcome from prostatectomy.


CONCLUSIONS
The penile cuff test fulfils the criteria as a useful clinical measurement technique applicable to the diagnosis and treatment planning of men with LUTS.
