The purpose of research was to examine diagnostic importance of the method of evaluation of the functional status of the lower urinary tract, which is based on daily monitoring of urodynamics. According to the urodynamic monitoring in 9 (75%) of 12 women with symptoms of imperative urination there were detected signs of detrusor instability, characterized by pronounced violation of adaptation functions of the lower urinary tracts, hypertonia of muscle structures, increased reflex excitability with spontaneous contractions of the bladder (from 1 to 12 uninhibited detrusor contractions per bladder filling phase). In other 3 women with imperative disuric symptoms there were not observed signs of detrusor overactivity. UM revealed great sensitivity in comparison with laboratory urodynamics in assessing detrusor activity. This method is particularly valuable in patients with complex forms of dysuria or subclinical manifestations of the disease, when a standard urodynamic study reveals no change and discorrelation of clinical manifestations of the disease and data of additional examinations takes place.
