Abstract
The Authors report their experience of post-voiding contraction (PVC) in 173 consecutive functional studies of the female lower urinary tract. A lack of significant correlations between the various urodynamic pictures was noted on the one hand and between the PVC and their extent on the other. It is suggested that there may be a connection between the presence of PVC and that of two clinical symptoms i.e. enuresis and mixed urinary incontinence; this was observed in 75% and 63.2% of the cases respectively. Considering PVC as not being a true form of detrusorial instability, in the genesis of which a possible reduction in pelvic muscle tone cannot be excluded, the utility of a vesico-sphincteric fuctional study is highlighted. This study aims at defining not only urethral activity, but also that of the pelvic plane musculature, due to the well-known interdependence between perineal and detrusorial activity.
