Why
  1. The study's listed conditions name Urinary Incontinence, Urge, a narrower term within Urinary Incontinence.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

UCon is a medical device for treatment of the symptoms of OAB and fecal incontinence (FI). It electrically stimulates the DGN through the skin to obtain modulated behaviour of the bladder musculature e.g., suppress undesired bladder activity to relieve the symptoms of the patient. This clinical investigation is a randomized, cross-over, single-site, prospective, early feasibility study, which is used to evaluate Ucon with respect to its initial clinical safety and device performance in a small number of males with OAB.

Read the detailed description

The purpose of the current investigation is to obtain information about the type of stimulation that Ucon provide (time limited vs. urge stimulation), would be the most effective and feasible for the treatment of non-neurogenic OAB symptoms in males.

Exclusion criteria

Exclusion Criteria:

  2. Subject has a Post Void Residual (PVR) of more than 100 ml or a Bladder Voiding Efficiency (BVE) of less than 75% (measured by uroflowmetry as the ratio of voided volume (VV) and total bladder capacity (VV+PVR)).
  3. Subject has an active infection in the genital area incl. skin infections and urinary tract infection.
  4. Subject has had botulinum toxin (BOTOX) treatment in the pelvic region within 6 months.
  5. Subject has used antimuscarinics or β3 agonists within 14 days weeks*.
  6. Subject has an implanted pacemaker, implantable drug pump or other active medical device (any medical device that uses electrical energy or other source of power to make it function).
  7. Subject is enrolled or planning to enrol in another clinical investigation or was enrolled in an drug study or medical device investigation within four weeks to enrolment.
  8. Subject has neuropathy to a degree that is presumed to diminish the effect of the electrical stimulation.
  9. Subject has a history of cancer in the pelvic region, are currently receiving cancer treatment, or has radiation-induced damage to the pelvic region.
  10. Subject has addictive behaviour defined as abuse of alcohol, cannabis, opioids, or other intoxicating drugs.
  11. Subject does not speak and understand Dutch.

    • If a subject is currently being treated with antimuscarinics or β3 agonists, he is allowed to be included in the investigation, however, a of 14 days is required before baseline can be established.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Washout period

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.

Study arms

  • Other
    Group A (Urge and Time limited)

    The participant self-administer electrical stimulation to the dorsal genital nerve (DGN) using UCon with a stimulation mode that is activated for 60 seconds by the participant when he experience urgency (urge stimulation).The urge stimulation can be activated repeatedly during the day as the participant wears the device from morning to evening at home for 14 days. Following a stimulation wash-out period (14 days), the participants then stimulates with UCon for another 14 days using the time limited stimulation mode.

    Device: Urge stimulation · Device: Time limited stimulation

  • Other
    Group B (Time limited and Urge)

    The participant self-administer electrical stimulation to the dorsal genital nerve (DGN) using UCon with a stimulation mode that is activated for 30 minutes once a day, at a time that is convenient for the participant. The participant uses the device at home for 14 days. Following a stimulation wash-out period (14 days), the participant then stimulates with UCon for another 14 days using the urge stimulation mode.

    Device: Urge stimulation · Device: Time limited stimulation

Interventions

  • DeviceUrge stimulation

    Participants will receive stimulation for 60 seconds, when they feel an urgency.

    Also known as: DGN stimulation, Neurostimulation

  • DeviceTime limited stimulation

    Participant will receive the stimulation as provided in time limited sessions (Range: 15 min - continuous), whenever it suits the participant during the day.

    Also known as: DGN stimulation, Neurostimulation

What researchers measure

Primary outcomes

  1. PRIMARY SAFETY: To evaluate adverse events [initial safety] of UCon for treatment of OAB symptoms in a home setting.

    Characterization of adverse events and anticipated adverse device effects associated with the use of UCon during the investigational period.

    Time frame: After 44 days (end of study)

  2. PRIMARY PERFORMANCE: To evaluate the ratio of treatment change [performance] of OAB symptoms using UCon in a home setting

    Ratio of subjects with at least 50% change in their OAB symptoms from baseline. Participants shall complete a 3-day bladder diary to report their symptoms. The symptoms related to OAB: * Urinary urgency is measured by number of urgency episodes/day. * Urinary frequency is measured by number of voidings/day. * Urgency urinary incontinence is measured by number of leaks preceded by urgency/day. * Nocturia is measured by number of voidings/night.

    Time frame: Change from baseline at 14 days, 30 days and 44 days (study end)

Secondary outcomes

  1. SECONDARY SAFETY: To identify the number of subjects experiencing adverse events associated with the use of UCon during the investigational period.

    Number of subjects experiencing adverse events and anticipated adverse device effects. Subjects will report on any experience associated with the use of UCon.

    Time frame: After 44 days (end of study)

  2. SECONDARY SAFETY: To evaluate the severity of adverse events associated with the use of UCon during the investigational period.

    Severity of adverse events and anticipated adverse device effects.The severity will be evaluated from the subjects' report on any experience associated with the use of UCon.

    Time frame: After 44 days (study end)

  3. SECONDARY PERFORMANCE: To evaluate whether subjects using UCon experience a change in their quality of life.

    Ratio of subjects with a change in their OAB quality of life measures as assessed by specific QoL questionnaires related to OAB condition (ICIQ-OAB, AOBq). An overall score with greater values indicates a worse symptom outcome.

    Time frame: Change from baseline at 14 days and 44 days (end of study)

  4. SECONDARY PERFORMANCE: To evaluate whether subjects using UCon experience a change in their treatment outcome (i.e. symptoms) after therapy.

    Ratio of subjects with a change in their treatment outcome (i.e. symptoms) assessed by the 7-point Patient Global Impression of Improvement (PGI-I) scale. Higher scores indicates a worse treatment outcome.

    Time frame: Change from baseline at 14 days and 44 days (end of study)

  5. SECONDARY PERFORMANCE: To evaluate the device and treatment acceptability of UCon.

    Ratio of subjects that accept UCon and DGN stimulation as assessed by a satisfaction survey recorded after each stimulation period.

    Time frame: After 44 days (study end)
