Brief Summary
-----------------
The aim of this study is to determine if the Sharklet catheter, with its unique surface micropattern, reduces infections in participants, when compared to a standard silicone catheter.

Official Title
-----------------
Does Micropattern on Urinary Catheter Surface Reduce Urinary Tract Infections?

Conditions
-----------------
Catheter Associated Urinary Tract Infections

Intervention / Treatment
-----------------
* Device: Sharklet Catheter insertion
* Device: Silicone Foley Catheter insertion


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Patient requires a chronic indwelling Foley catheter for at least 3 days. Catheters will not remain indwelling greater than 30 days at a time Patient is more than 18 years of age Patient is able to give informed consent Patient is able to attend follow-up sessions Exclusion Criteria: Patient is less than 18 years of age Patient is pregnant Patient with a known allergy to silicone Patient has urinary tract anatomic abnormality that would prevent placement of a standard Foley catheter Patient unable to accommodate the catheter Patient has an active urinary tract infection (UTI) or other diagnosed infection that is untreated. Patient currently taking (or expected to take) more than a single dose of antibiotics for prevention of other infections during the catheter indwell period Patient has uncontrolled fecal incontinence (uncontrolled stool/poop passage) Patient is unable to feel and/or communicate their symptoms Informed consent is unable to be obtained Patient is unable or unwilling to comply with the study follow-up schedule Patient has a medical condition or disorder that would limit life expectancy to less than 30 days or that may cause non-compliance with the protocol or confound the data analysis Any other reason that if in the opinion of the investigator would make the patient unsuitable for enrollment in the study

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Catheter scrapings examined for colonization/biofilm burden and compared to the urine screen collected from the participant (cfu/mL) | Determine if there will be less adherent bacteria/biofilm to the Sharklet catheter compared to the controls. | 12 weeks | 
| Number of symptomatic Urinary tract infections (UTIs) determined by urine culture. | Determine number of symptomatic UTIs between the 2 groups as determined by urine culture. | 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of bacteremia | Incidence of bacteremia following CA-SUTI | 12 weeks | 
| Incidence of Crustation | Incidence of catheter obstruction/encrustation requiring removal | 12 weeks | 
| Incidence of Discomfort | Incidence of significant discomfort/pain requiring removal | 12 weeks | 
| Surface analysis of the type of bacteria found on each catheter | Surface analysis (e.g., Scanning Electron Microscopy) of removed catheters for qualitative assessment of bacterial colonization | 12 weeks | 
| Surface analysis of the amount of encrustation | Surface analysis (e.g., Scanning Electron Microscopy) of removed catheters for qualitative assessment of encrustation | 12 weeks | 
| Surface analysis of the biofilm formation | Surface analysis (e.g., Scanning Electron Microscopy) of removed catheters for qualitative assessment of biofilm formation | 12 weeks |
