Randomized Study of Silq Urinary Catheter

Not Applicable

Completed

• Conditions: Biofilm Formation; UTI
• Interventions: Device: Long-term indwelling Foley catheter

• Registration Number: NCT04841226
• Lead Sponsor: Silq Technologies Corporation

Brief Summary

To assess the ability of the Silq ClearTract™ 100% Silicone 2-Way Foley Catheter to reduce biofilm formation in subjects that require a long-term indwelling Foley catheter when compared to other commercially available urinary catheters.

Detailed Description

A prospective, randomized, multi-center, post-market study in subjects that require a long-term indwelling Foley catheter.

A randomly assigned catheter will be inserted using standard techniques. Non-surgical subjects will rate the level of pain associated with the insertion procedure using the visual analog scale (VAS). A urine sample will be collected immediately after catheter insertion, in order to generate a baseline urinalysis and urine culture.

Follow-up visits will be performed on Day 28, or upon catheter removal, whichever occurs first. The catheter will be removed on Day 28 or earlier if clinically indicated. The removed catheter will be processed and sent to the core laboratory for analysis. Urine will be collected immediately prior to catheter removal in order to conduct urinalysis and urine culture. Subject will rate level of pain associated with the removal procedure using the VAS. The subject will also fill out a questionnaire about their experience with the catheterization immediately after catheter removal. Subjects will then be exited from the study.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 158

Inclusion Criteria

1. Male or female age ≥ 18 years old;
2. Requiring indwelling 16Fr Foley catheter for at least 7 days;
3. Able and willing to comply with study procedure; and,
4. Able and willing to give informed consent.

Exclusion Criteria

1. Allergy or sensitivity to any catheter materials used in this study;
2. Known urethral stricture which, in the opinion of the investigator, could influence the subject's evaluation of the catheter;
3. Planned Prophylactic use of antibiotics for CAUTI or any other infection beyond day 1 of the study (catheter implantation);
4. Symptomatic UTI being treated with antibiotics (as determined by the study PI, including at least one of the following: fever, chills, headache, burning sensation, burning of urethra or genital area, blood in urine, foul smelling urine and ≥ 10,000 cfu/mL);
5. Any other infection being treated with antibiotics at the time of catheter implantation;
6. Subjects requiring bladder irrigation during the study (an active voiding trial in surgical subjects prior to catheter removal is allowed);
7. Currently enrolled in another interventional clinical trial;
8. Any other condition that, in the opinion of the investigator, precludes study participation or poses a significant hazard in case of study participation; and
9. Females who are pregnant or breastfeeding or who plan to become pregnant during the study.
