This research aims to establish normal reference ranges for urodynamics parameters in healthy adults aged 18 to 45 using the Glean Urodynamics System. The study is open-label and interventional, focusing on evaluating bladder and abdominal pressure measurements among participants without known urinary tract conditions. Participants will have the Glean Urodynamics System inserted, which includes a bladder pressure sensor, abdominal pressure sensor, an in-clinic uroflowmeter, and software applications. After an in-clinic ambulatory monitoring period, participants will be discharged with the bladder sensor in place for continued monitoring outside the clinic for up to 24 hours. The sensor will be removed within 24 hours after insertion. During the study, participants will undergo in-clinic monitoring followed by home monitoring with the sensor. A follow-up phone call will occur 7 days after sensor removal. Researchers will measure vesical pressure ranges during the procedure and monitor participants for any changes or issues related to the device. The total participation time includes the monitoring period plus follow-up contact to ensure safety and data completeness.

This table compares participation in this trial with other options available for this condition. The information is drawn from published research and the trial’s study details and is provided for educational purposes only.
| Factors | Glean Urodynamics System | Standard catheter‑based urodynamics |
|---|---|---|
| What it is | A catheter‑free, ambulatory system measuring bladder and abdominal pressures along with uroflowmetry using wearable sensors and software apps in a clinic setting. | The current clinical standard involves catheter‑based invasive urodynamic testing following International Continence Society good urodynamic practice. |
| Role in study | Used as the investigational device to establish normative urodynamic parameter ranges in healthy adults. | Not part of this trial; serves as external reference for diagnostic norms and clinical context. |
| Primary use | Recording normative bladder and abdominal pressure parameters during natural voiding in healthy adults. | Assessing lower urinary tract physiology to diagnose dysfunction through catheter‑based cystometry and pressure‑flow studies. |
| How it is performed | Sensors placed non‑invasively in clinic to capture pressures and flow during natural filling and voiding without urethral catheter. | Requires insertion of urethral and abdominal catheters with controlled bladder filling for cystometry and pressure‑flow studies. |
| Evidence status | Evidence being generated for normative ranges in healthy adults; feasibility and safety reported in a preliminary study. | Widely validated diagnostic method with standardization by the International Continence Society. |
| Important risks | Safety profile under evaluation; early feasibility study reports acceptable safety in healthy adults. | Known risks include discomfort, urethral injury, infection associated with catheter insertion. |
| Important limitations | Normative data from a healthy, age‑limited sample; not yet validated in broader or patient populations. | Invasive nature may alter bladder behavior; requires controlled filling that might not reflect natural voiding. |
| Patient impact | May offer more natural voiding conditions and improved comfort compared with invasive catheter testing. | Provides direct diagnostic information but can be uncomfortable and less reflective of natural voiding behavior. |
