Study summary

The goal of this prospective trial is to evaluate the feasibility, efficacy, and safety of the Glean Urodynamics System (GUS) for use in the clinic to collect vesical pressure data in adult males and females with lower urinary tract symptoms.

The main question[s] it aims to answer are:

  • What is the feasibility, efficacy, and safety of GUS for use in clinical to collect vesical pressure data in adult males and females with lower urinary tract symptoms?

Participants will undergo a planned conventional urodynamics exam after which the Glean Sensor will be inserted and ambulatory urodynamics will be performed with the sensor indwelling in the bladder after which the sensor will be removed.

What researchers measure

Primary outcomes

  1. Percentage of Participants With Insertion Success

    Percent of insertion attempts of the Glean sensor deemed successful

    Time frame: during the insertion procedure of a device

  2. Percentage of Participants With a Device-related SAE

    Device-related serious adverse events

    Time frame: up to 2 weeks

  3. Percentage of Participants With Removal Success

    Percent of removal attempts of the Glean sensor deemed successful

    Time frame: during the removal procedure of a device

Secondary outcomes

  1. Percentage of Participants Rating Overall Comfort of Glean Urodynamics as Comfortable or Extremely Comfortable

    Number of participants rating the overall comfort of Glean Urodynamics at comfortable or extremely comfortable

    Time frame: asked at end of Glean Urodynamics procedure

Results

Posted Dec 18, 2025
Limitations and caveats
Study not powered for any outcome or any comparisons; small sample size limits validity, generalizability, and applicability; order of procedures (i.e., conventional UDS occurring before Glean UDS) and the variability of standard-of-care may have influenced results such as attribution of harm; and participant recall bias due to the removal of the Glean sensor being the last procedure experienced (Kim, 2025).
