An intelligent wearable device based on electrical impedance tomography for dynamic and accurate monitoring of voiding function in patients with benign prostatic hyperplasia: protocol for a single-centre self-controlled diagnostic consistency study

Benign prostatic hyperplasia (BPH) is a common condition that causes lower urinary tract symptoms (LUTS) in middle-aged and elderly men. Existing bladder function monitoring methods, such as ultrasound and urodynamic studies (UDS), have limitations including invasiveness, lack of dynamic capability, poor portability, and susceptibility to psychological interference. Electrical impedance tomography (EIT) technology, with its potential for non-invasiveness, non-ionizing during monitoring, portability, and real-time dynamic imaging, offers a new approach to address this clinical challenge.
