Abstract
The urodynamics of the lower urinary tract, the clossure urethral mechanism and EMG activity of the pelvic floor, were studied in the group of patient (n = 14) in consequence with the vaginal delivery. Approximately 6-9 weeks after the delivery a slight decrease of the functional urethral length (P < 0.05) and the transmission factor (P < 0.05) were observed. On the contrary, EMG activity of the pelvic floor was significantly increased (P < 0.05) after the puerperium. - The authors suppose, that the decrease of pelvic floor contractility seems to be a physiological phenomenon given by mechanical, vascular and hormonal factors, that should facilitate the normal vaginal delivery. The relations between the changes of EMG activity and parity, birth weight or labour injury were not verified.
