A wearable bladder monitoring device is disclosed (1) comprising securing means (27, 29) for securing the device to a subjects (40) body a phased array (11) of ultrasound transducers (10) having configurable output frequencies a configurable phased array controller (13) adapted to control the phased array to direct ultrasound beams (30, 30, 30") into the subjects body under a plurality of discrete beam angles and to collect echo signals (31, 31, 31") of said ultrasound beams, wherein the phased array controller (13) is adapted to direct a set of ultrasound beams (30, 30, 30") into the subjects body for at least a subset of said discrete beam angles in response to a configuration instruction defining the respective output frequencies of the ultrasound beams in said set and a device communication module (21) for communicating data pertaining to said echo signals to a remote device (5) to facilitate the remote processing of said data and to receive said configuration instruction from the remote device. Also disclosed is a wearable bladder monitoring system adapted to generate such a configuration instruction for the estimation of the degree of turbidity of urine contained in the monitored bladder with the wearable bladder monitoring device, as well as a computer-implemented method and computer program product for facilitating such urine turbidity estimation.
