[Detrusor activity and motor neurons firing during micturition: analysis by means of modeling of urodynamic tracings]

BACKGROUND: To use a computer assisted analysis of urodynamic tracings (VBN method) in order to propose a quantitative description of the relationship between detrusor activity and firing of efferent motor neurons. METHODS: Modeling of the nervous control implies three definitions of the detrusor excitation: (1) related to the contractile force (EF), (2) related to the calcium turnover (ECa) and (3) ratio of firing motor neurons (rr). The associate variables have been computed from each uroflow
