Abstract
The present relates to a method, system and a device for non-invasive detection of urine flow from the bladder into the kidney(s). The method, system and device rely on measurements made at distinct time points and can be used to detect Vesicoureteral reflux. The method, system and device are designed to detect changes in urine volume in the ureter(s), bladder and/or kidney(s). The method and device measure conductivity changes by bioelectrical impedance or electrical impedance tomography technology.
