Glean™ Urodynamics System: Introducing a New Era of Ambulatory Urodynamics – Summary
Why Watch: This presentation introduces the Glean™ Urodynamics System, a groundbreaking, wireless, catheter‑free ambulatory solution for measuring bladder function. Dr. Jason M. Kim, MD, demonstrates how it addresses key limitations of conventional urodynamics, offering enhanced patient comfort, workflow efficiency, and diagnostic accuracy—making it highly relevant for clinicians aiming to modernize bladder diagnostics.
In this presentation, Dr. Jason M. Kim, MD, Director of Women’s Pelvic Health & Continence Center and Professor of Urology at Stony Brook Medicine, Stony Brook, New York, outlines the limitations of traditional urodynamic testing—namely, non‑physiologic rapid bladder filling, catheter‑induced discomfort, frequent voiding failures, and intense resource demands.
He introduces the Glean™ System, a compact, wireless bladder pressure sensor inserted via a sheath into the bladder. A retrieval string remains outside (taped appropriately), enabling easy removal—typically in under 6 seconds. The device transmits data via Bluetooth, allowing patients to go home and perform natural activities, potentially including overnight monitoring.
In a prospective, single‑arm, multicenter study (the MUSE trial), 33 participants underwent standard urodynamics followed by Glean™ testing. Successful sensor placement occurred in 97% (32/33), with a median insertion time of around 34 seconds and removal in about 6 seconds. All patients could void with the device in place—a significant advantage over conventional testing. Minor, self‑limiting adverse events occurred; no serious events were reported.
Clinician feedback was overwhelmingly positive: 81% found insertion easy or very easy, and 97% found removal easy or very easy. Patient-reported comfort improved, and the Glean™ system achieved a positive net promoter score (22.6), whereas conventional urodynamics scored negatively.
Dr. Kim highlights the device’s practical advantages: low capital cost, portability, and minimal training requirements. These enable urodynamics to be performed across more clinic locations and reduce wait times.
