Early Foley Catheter Removal After Diverticular Colovesical Fistula Repair

February 19, 2026 updated by: Karim Alavi
Patients undergoing surgical repair of colovesical fistula will have have "early" (post-operative day 3) cystogram and removal of bladder catheter. Outcomes from the "early" group will be compared to historical "late" group data to determine if early bladder catheter removal is safe.

Study Overview

Status

Status

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

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.

Detailed Description

There is defined time for foley/bladder catheter removal after colovesical fistula repair in the current surgical literature. This study will be a prospective cohort study evaluating outcomes after early foley catheter removal (on post-operative day 3), specifically bladder leak, 30-day readmissions and adverse events. This cohort will be compared to a retrospective "late" group, who had foley catheter removal later in their hospital course.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Description

Inclusion Criteria:

  • Adults aged 18 and over
  • Undergoing surgical repair of diverticular colovesical fistula

Exclusion Criteria:

  • Patients with active and untreated genitourinary cancers
  • Subjects with known or suspected Inflammatory Bowel Disease as the cause of colovesical fistula.
  • Individuals who are not expected to regain normal bladder function after surgery as defined by either pre-existing bladder dysfunction with chronic indwelling urinary catheter, supra-pubic catheter, or surgical urinary diversion
  • Individuals who require re-operation prior to Foley removal

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Foley catheter removal day 2 or 3 post-operative procedure
According to review of internal clinical practices, the average duration of catheterization after Colovesical Fistula (CVF) repair is 10.8 days after CVF repair. The intervention in this study removes the Foley Catheter at 2 to 3 days post CVF repair.
Procedure: Removal of Foley Catheter 2 to 3 days post Colovesical Fistula (CVF) repair surgery
According to review of internal clinical practices, the average duration of catheterization after Colovesical Fistula (CVF) repair is 10.8 days after CVF repair. The intervention in this study removes the Foley Catheter at 2 to 3 days post CVF repair.

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
Presence of positive urine leak on post-operative day 3 cystogram
Time Frame: up to 3 days post surgery
Participants cystograms will be reviewed to detect positive urine leak, 2 to 3 days post surgery.
up to 3 days post surgery

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
