This bladder scanner reminds us of the higher ability and versatility to monitor beyond normal and postoperative urinary retention. It reconstructs the bladder shape and measures its volume using multi-plane scanning in an automatic process. No sonographer is required for operation. This allows the assessment of individual situations with some level of details. It will help determine appropriate care, assist bladder retraining, improve the quality of life of older adults and preserve their dignity. This bladder scanner is, currently, a device widely used in elderly homes, hospitals, and NGOs.
