9000 URETHRA STUDY: a Study About Urethroplasty for Urethral Stricture Disease

January 2, 2024 updated by: University Hospital, Ghent

9000 URETHRA STUDY: a Prospective, Observational Study About Urethroplasty for Urethral Stricture Disease

It has been demonstrated that urethroplasty should be considered the gold standard treatment for urethral stricture disease as it yields higher long-term success rates than endoscopic treatment options such as direct vision internal urethrotomy (DVIU) or dilation. Many data about these procedures exist, although most of the publications about urethroplasty are retrospective and involve a tremendous risk of bias. To address these issues, this study is designed to prospectively gain evidence about this matter in all patient subgroups facing a potential treatment with urethroplasty: native men, native women, transmen, transwomen and children.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

6 years to 100 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Native men, native women, transmen, transwomen and children with urethral stricture disease.

Description

Inclusion Criteria:

  • Voluntarily signed written informed consent according to the rules of Good Clinical Practice (Declaration of Helsinki) and national regulations.
  • Patient age ≥ 6 years.
  • If a patient reaches the age of 18 years, he or she will have to provide a new voluntarily signed written informed consent. All patients reaching the age of 18 years will be contacted by the Principal Investigator or Subinvestigator to provide a new voluntarily signed written informed consent.

Exclusion Criteria:

- Absence of signed written informed consent and thus a patient unwilling to participate.

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
Failure-free survival
Time Frame: From date of surgery until the date of stricture recurrence or date of death from any cause, whichever came first, assessed up to 120 months postoperatively
Interval between operation and latest follow-up moment at which the patiënt remains failure-free
From date of surgery until the date of stricture recurrence or date of death from any cause, whichever came first, assessed up to 120 months postoperatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in erectile function
Time Frame: From the date of preoperative questionnaire completion until 24 months postoperatively.
Assessment preoperatively and postoperatively using the IIEF-5 (International Index of Erectile Function) questionnaire (a 5-item questionnaire, total score on 25, higher score indicating better erectile function).
From the date of preoperative questionnaire completion until 24 months postoperatively.
Change in ejaculatory function
Time Frame: From the date of preoperative questionnaire completion until 24 months postoperatively.
Assessment preoperatively and postoperatively using the MSHQ-EjD (Male Sexual Health Questionnaire - Ejaculatory Dysfunction) short form questionnaire (a 3-item questionnaire, total score on 15, higher score indicating better ejaculatory function)
From the date of preoperative questionnaire completion until 24 months postoperatively.
Change in urinary function
Time Frame: From the date of preoperative questionnaire completion until 24 months postoperatively.
Assessment preoperatively and postoperatively using the ICIQ-MLUTS (International Consultation on Incontinence Questionnaire - Male Lower Urinary Tract Symptoms) module questionnaire (a 6-item questionnaire, total score on 24, higher score indicating more urinary bother)
From the date of preoperative questionnaire completion until 24 months postoperatively.
Change in urinary continence
Time Frame: From the date of preoperative questionnaire completion until 24 months postoperatively.
Assessment preoperatively and postoperatively using the ICIQ-UI (International Consultation on Incontinence Questionnaire - Urinary Incontinence) short form questionnaire (a 3-item questionnaire, total score on 21, higher score indicating more incontinence).
From the date of preoperative questionnaire completion until 24 months postoperatively.
Change in quality of life
Time Frame: From the date of preoperative questionnaire completion until 24 months postoperatively.
Assessment preoperatively and postoperatively using the EQ-5D-3L questionnaire (a 5-item questionnaire generating a digit score, each of the 5 items can be scored with 1, 2 or 3 (e.g. 11213), higher digit score indicating lower quality of life).
From the date of preoperative questionnaire completion until 24 months postoperatively.
Change in general quality of life
Time Frame: From the date of preoperative questionnaire completion until 24 months postoperatively.
Assessment preoperatively and postoperatively using the EQ-VAS (Visual Analogue Scale) (a numeric scale ranging from 0 to 100, higher score indicating better quality of life).
From the date of preoperative questionnaire completion until 24 months postoperatively.
