Functional Outcomes of the Miami Pouch Continent Cutaneous Urinary Diversion: A Quality of Life Study (MiaDIG)

November 6, 2026 updated by: Hospices Civils de Lyon

Functional Urinary and Digestive Outcomes After Miami Pouch: A Quality-of-Life Study (MIADIG)

The Miami Pouch is a continent cutaneous urinary diversion using the plicated right colon and the ileocecal valve as a catheterizable continent stoma. Despite its long history, functional outcomes remain poorly reported, with no consensus on continence definition or standardized assessment tools.

This single-center cross sectional cohort study evaluates functional outcomes in patients who underwent Miami Pouch urinary diversion at Hôpital Lyon Sud (Hospices Civils de Lyon, France) between 2015 and 2025. Patients were identified through institutional medical coding (PMSI) and contacted by telephone to complete validated patient-reported outcome measures.

The primary objective is to assess stomal continence using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF).

Hypothesis: The Miami Pouch provides acceptable long-term stomal continence with limited impact on digestive function.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Consecutive patients who underwent Miami Pouch continent cutaneous urinary diversion at the Urology Department of Hôpital Lyon Sud, Hospices Civils de Lyon, Pierre-Bénite, France, between 2015 and 2025. 35 patients estimation.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Miami pouch

Adult patients who underwent Miami Pouch continent cutaneous urinary diversion at the Urology Department of Hôpital Lyon Sud (HCL) between 2015 and 2025, with a minimum postoperative follow-up of 6 months
Other: Patient reported outcome measures

Patients completed four validated questionnaires by telephone: the ICIQ-SF (urinary symptom frequency and impact), the SF-Qualiveen (urinary quality of life in neurogenic and non-neurogenic patients), a modified 20-item Gastrointestinal Quality of Life Index (digestive quality of life), and the Bristol Stool Scale (stool consistency)

Other: 24-Hour Stomal Pad Test

Patients performed a self-administered 24-hour stomal pad test at home. Absorbent pads were weighed before and after placement over the stoma. Total pad weight gain (grams) over 24 hours was used as an objective measure of stomal urinary leakage.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Stomal Continence Rate
Time Frame: 6 months post-surgery

Stomal continence classified into three categories based on ICIQ-SF questionnaire :

  • No Leakage
  • Occasional Leakage
  • Daily Leakage. Social continence defined as No Leakage or Occasional Leakage.
6 months post-surgery

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
