SUMMARY. The purpose of the study is to increase the effectiveness of treatment of patients with an overactive bladder on the basis of determining the functional state of the lower urinary tract and developing pathogenetically based treatment methods.
Material and Methods. We have examined and treated 64 patients with an overactive bladder. All patients underwent a comprehensive examination using both generally accepted and special diagnostic methods.
Diagnostics of functional disorders of the urinary bladder was carried out using electromyography (EMG), which was performed on the MERCUR 4000 device. The analysis of biopotentials was carried out based on the average voltage value, which was taken from the detrusor and its sphincter apparatus with the help of special electrodes-catheters. EMG was performed before the start of treatment, as well as after the 1st, 3rd and 6th courses of treatment using electrical stimulation (ES) of the bladder. Electrical stimulation of the lower urinary tract was carried out non-invasively by the percutaneous method using the "Amplipuls" device, taking into account the areas of segmental innervation.
Results. After the end of the treatment, a positive effect and correlation of clinical and electromyographic indicators was noted in 87.1 % of patients. In 12.9 % of cases, positive dynamics were not noted during EMG analysis and evaluation of treatment effectiveness. When evaluating the results of treatment, a gradual decrease in the average value of the difference in detrusor biopotentials was obtained in men by 14.3 % and in women by 15.4 %.
Conclusions. Electromyographic studies of the urinary bladder and its sphincter apparatus made it possible to objectively characterize the functional state of the lower urinary tract, which makes it possible to improve the quality of diagnosis of patients with an overactive bladder and evaluate the effectiveness of treatment.
