About this study

This study assessed the effect of different InterStim rate settings on voiding diary outcomes. Specifically, the study evaluated how 3 different rate settings affected the number of urinary incontinent episodes per day collected through a voiding diary. The study also evaluated how the 3 different rate settings affected other voiding diary measures including number of voids per day, degree of urgency before each void, number of pads used per day, and number of fecal incontinent episodes, questionnaires, and adverse events.

Being tested
InterStim Therapy at rate 5.2 Hz, InterStim Therapy at rate 14 Hz, InterStim Therapy

What participants receive

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

  • InterStim Therapy at rate 5.2 HzDevice

    All subjects enrolled in this study were programmed to this rate setting for a 1-week period.

  • InterStim Therapy at rate 14 HzDevice

    All subjects enrolled in this study were programmed to this rate setting for a 1-week period.

  • InterStim TherapyDevice

    All subjects enrolled in this study were programmed to each rate setting (low, medium, high) for a 1-week period.

What is being measured

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

  1. Number of Urinary Incontinent Episodes Per Day

    In a diary, subjects are asked to rate each urine leaking episode at 'None', 'Slight', 'Moderate' or 'Heavy'. The urinary incontinence was counted if there is any degree of leaking, from 'Slight' to 'Heavy'. The total number of urinary incontinence was calculated per day.

    Measured: three weeks

Secondary outcomes (2)
  1. Number of Voids Per Day

    In a diary, subjects are asked clarify each void as 'urine', 'fecal' or 'both'. Either 'urine' or 'both' are counted as void for this analysis. The total number of voids was calculated per day.

    Measured: three weeks

  2. Number of Pads Per Day

    In a diary, subjects are asked to provide number of pads they used per day.

    Measured: three weeks

Questions about this trial

What is this clinical trial studying?

A study testing InterStim Therapy at rate 5.2 Hz, InterStim Therapy at rate 14 Hz and InterStim Therapy in people with Urgency Frequency and Urinary Urge Incontinence, run by MedtronicNeuro at 1 site in United States.

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 10 inclusion and 18 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: finished, as of the sponsor's last update on 27 May 2013. 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 United States. 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?

Yes. Results are posted in the registry (first posted 2 May 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Urinary Incontinent Episodes Per Day (time frame: three weeks). 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 27 May 2013.
