简要总结
Benign Prostatic Hyperplasia (BPH) is a common condition that can cause bothersome urination problems and reduce quality of life. Accurately measuring how the bladder empties is important for diagnosis and treatment, but current methods like uroflowmetry can be inconvenient and are done only at a clinic.
This study aims to test a new, non-invasive smart wearable device that uses Electrical Impedance Tomography (EIT) to monitor bladder function in patients with BPH. The device is worn on the lower abdomen. In this study, participants will use this EIT device while also undergoing the standard uroflowmetry test. The main goal is to see how well the measurements from the new device (like urine flow rate and volume) agree with those from the standard test.
The study hopes to show that this wearable device can accurately and comfortably track bladder function over time. If successful, it could lead to a new tool for doctors to better monitor patients with BPH, even potentially at home.
详细描述
Background: Benign Prostatic Hyperplasia (BPH) is a prevalent cause of Lower Urinary Tract Symptoms (LUTS). Current objective assessment tools like uroflowmetry have limitations, including single-point measurement and the need for a clinical setting. Electrical Impedance Tomography (EIT) is a non-invasive, radiation-free imaging technique that shows promise for dynamic, real-time monitoring of internal organs. Preliminary work by our team has developed a wearable EIT system capable of 3D reconstruction.
Objectives: The primary objective is to evaluate the accuracy and agreement of the EIT wearable device in determining key uroflowmetry parameters (maximum flow rate, average flow rate, voided volume) against traditional uroflowmetry as the reference standard. Secondary objectives include assessing its capability for dynamic bladder volume monitoring and exploring an AI-based analysis framework.
Study Design: This is a single-center, self-controlled, diagnostic consistency trial.
Inclusion criteria:
- Patients with BPH who need urodynamic tests to further evaluate the underlying pathophysiology of LUTS prior to invasive treatment.
- Patients who understand and agree with the written informed consent, and voluntary to participate in the study. .
