About this study

Official title: PROSPECTIVE STUDY EVALUATING THE SAFETY AND EFFECTIVENESS OF ADJUSTABLE CONTINENCE THERAPY (ACT) BALLOONS FOR THE MANAGEMENT OF URINARY INCONTINENCE IN CHILDREN WITH BLADDER EXSTROPHY OR INCONTINENT EPISPADIAS

The purpose of this study is to evaluate the effectiveness and safety of a minimally invasive surgical procedure with ACT (Adjustable Continence Therapy) balloons implantation for the treatment of urinary incontinence in children with bladder exstrophy or isolated epispadias.

The ACT therapy consists of two small adjustable silicone balloons connected with a tubing to a port, surgically placed around the bladder neck, one on each side of the urethra.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ACTDevice

    Implantation of ACT balloon, Uromedica (Irvine, CA, USA) periurethrally at the bladder neck. The ACT system is a permanent implant designed for the correction of incontinence in patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of the clinical impact of ACT balloon on urinary continence with pad weight

    Therapeutic success will be based on whether patients demonstrate at least a 50% reduction in 24 hour Pad weight at 6, 12 and 24 months follow-up compared to the pad weight results at baseline.

    Measured: 24 months

Secondary outcomes (4)
  1. Number of pads per day (voiding diary)

    Change of number of peds changed per day from baseline to 6, 12 and 24 months (the best : 0 pads changed a day).

    Measured: 6, 12 and 24 months

  2. Number of incontinence episodes per day (voiding diary)

    Change in number of incontinence episodes per day from baseline to 6, 12 and 24 months (the best : 0)

    Measured: 6, 12 and 24 months

  3. PIN-Q questionnaire

    Change on validated incontinence quality of life questionnaire from baseline to 6, 12 and 24 months

    Measured: 6, 12 and 24 months

  4. Incidence of urethral stricture and device erosion after ACT implantation

    Cumulative incidence of ACT related clinically relevant urethral structure and device erosions (the best : 0)

    Measured: 6, 12 and 24 months

Questions about this trial

What is this clinical trial studying?

A study testing ACT in people with Bladder Exstrophy, run by Assistance Publique Hopitaux De Marseille at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 28 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluation of the clinical impact of ACT balloon on urinary continence with pad weight (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Oct 2026.
