Sponsor's own description
Purpose To measure the impedance of the bladder during the urodynamic study to see if changes in the impedance value occur as the bladder volume changes in pediatric patients aged 5-12 years along with its leg time. In addition, during the urodynamics test, the heart rate is measured at the same time to confirm the pulse change due to the filling of the bladder. -Background of the study (Method of identifying urinary bladder using impedance) In order to overcome the limitation of the method of checking the urinary volume in the bladder using ultrasound, the measurement of the impedance in the bladder is proposed as an alternative. Impedance measurement is non-invasive, very low cost, easy to measure and has a great advantage that it can be continuously measured in everyday life. In fact, early studies suggest that impedance measurement in the bladder is helpful in identifying urinary bladder capacity. On the other hand, there are two disadvantages to the urinary bladder identification method using impedance. One is the relative aspect that the impedance value changes according to the patient, and the other is the time lag time from the measurement point to the point when the impedance change appears. * In order to overcome this problem of impedance-based urinary bladder identification method, we measured impedance change according to real-time change of urinary volume in bladder during urodynamic study. * Background of the Invention (Pulse changes due to changes in urinary volume in bladder) It is known that when the urine enters the urinary bladder, the autonomic nervous system detects and regulates the heart rhythm, and the change of heart rate has not been reported in pediatric patients.
