Urinary Catheters
Urinary catheters are hollow tubes inserted through the urethra into the bladder to drain urine. The tubing is firm enough to advance but flexible enough to follow the urethral pathway. Catheters help people who are unable to empty their bladder on their own. When the bladder does not empty regularly, urine can build up, cause discomfort, and increase the risk of complications, including kidney problems.
Catheter use is often temporary, such as after surgery or an acute illness. Some injuries or chronic urologic conditions, however, may require long-term or even permanent catheterization. Catheters are available in many sizes, materials, and designs so clinicians can match the device to each patient’s needs.
The following sections review how modern urinary catheters are constructed, how they are used, and how different designs compare, including features found in Cure catheters. A side-by-side comparison chart highlights several widely used catheter models.
Indications
Urinary catheters are generally used when normal bladder emptying is not possible or safe.
- Prolonged immobilization
- Loss of voluntary bladder control
- Urinary incontinence
- Acute urinary retention
- Bladder outlet obstruction
- To aid healing of open perineal or sacral wounds
- To help prevent skin breakdown from constant moisture
- Urologic surgical procedures
- Prolonged surgical procedures
- Surgeries with large-volume infusions or diuretics
Contraindications
Certain findings suggest that catheter insertion may be unsafe.
- Suspected urethral trauma
- Scrotal hematoma
- Pelvic fracture with possible urethral injury
- High-riding prostate on exam
- High suspicion of a urethral tear
- Blood at the urethral meatus
Inappropriate Uses
Catheters should not be used when safer alternatives are available.
- Substitute for routine nursing care in individuals with incontinence
- Obtaining urine samples when the person can urinate voluntarily
Catheter Construction
Urinary catheters are most often made from three materials: polyvinyl chloride (PVC), silicone, and latex. Silicone and latex are the most common materials used for indwelling urinary catheters. Many models also have a surface coating to make insertion smoother and to help lower infection risk. Common coatings include hydrophilic layers, silicone-elastomer, polytetrafluoroethylene (PTFE), silver-based finishes, and PTFE-type Teflon. These coatings reduce friction during use and may help decrease irritation and inflammation.
PVC
Polyvinyl chloride (PVC) is a medical-grade plastic used in many healthcare products, including tubing, exam gloves, urine leg bags, and blood collection bags. In catheter form, PVC is clear, which allows staff to see urine color and flow. It is soft and pliable enough to pass through the urethra while remaining firm enough to guide into the bladder.
Advantages
- Smooth eyelets or drainage holes to reduce resistance during insertion
- Clear material for visual observation
- Latex-free construction
- Color-coded funnels to identify French size
- Funnels that support gripping and drainage control
Disadvantages
- May contain plasticizers such as DEHP or DiNP, which are under review for potential health risks
- Manufacturing and disposal can impact the environment
- Concerns exist about long-term exposure to some plasticizers in sensitive populations

Silicone
Silicone is an inert synthetic polymer used widely in long-term medical devices. It is flexible, stable in a range of temperatures, and resistant to many chemicals. Silicone catheters are biocompatible, meaning the material is designed to limit interaction with body fluids and tissues. This helps support comfort and durability during use.
Advantages
- Firm yet flexible shaft for controlled insertion
- Resists reaction with body fluids
- Biocompatible material
- Less likely to irritate cells and tissues
- Less prone to mineral deposits on the surface
- Surface that can be less favorable to bacterial adherence
- Latex-free construction
- Often selected for longer indwelling use when clinically appropriate
Disadvantages
- Softer structure can be more prone to kinking or deformation in some situations
- Rare reports of catheter tip damage or breakage
- May not be suitable for all patients, depending on individual sensitivity
- Typically higher cost than latex options

Latex
Latex catheters are soft and highly flexible, which can support comfort and ease of placement. They are often a lower-cost option. Many latex catheters include an outer coating, such as silicone, silicone elastomer, or hydrogel, to help reduce friction and limit surface irritation.
Advantages
- Very flexible material
- Generally easy to insert when properly lubricated
- Often less expensive than other materials
- Commonly used for short- to moderate-duration catheterization when appropriate
Disadvantages
- Surface can be prone to mineral deposits or encrustation over time
- Encrustation may increase friction and discomfort during removal
- Latex allergy or sensitivity is common in some patient groups
- Higher risk of hypersensitivity reactions in individuals with latex sensitivity
- May be more irritating to the urinary tract than latex-free options in some cases

Catheter Coatings
Coatings
Urinary catheters are commonly used in chronic care facilities and senior facilities throughout the world. Many of the problems associated with catheters include infection, encrustation, tissue trauma, and inflammation. These issues can be correlated to the catheter surface. Many of the shortcomings with catheter surfaces can be alleviated by simply adding a friction-reducing coating. Several coatings are now in use, including hydrogel, Teflon,® and silicone. Hydrophilic coatings appear to be the best option. Hydrogel provides a smooth, soft surface with lubricating properties.21
Hydrophilic
A hydrophilic surface coating is a polymer layer that readily absorbs liquid. When immersed in water, it swells to a smooth, slick film. The film provides for easier insertion into the body. A hydrogel-coated latex urinary catheter has a smooth surface with fissures, ripples, and furrows filled with a slick cover. The topography of the hydrophilic coated latex surface compares with a 100% silicone catheter.22
Silicone
A silicone coating provides a smooth surface. A silicone outer layer on a latex catheter provides a smooth covering to help reduce patient discomfort and irritation during insertion.
Silicone-Elastomer
A silicone-elastomer coating is a hydrophobic material that repels moisture. This layer helps to protect the urethral from irritation. It offers a glassy surface for a less painful insertion.
Polytetrafluoroethylene
Polytetrafluoroethylene (PTFE) or Teflon is a fluorocarbon-based polymer that lines the catheter to reduce friction by providing a smooth surface. PTFE coatings increase torque control, flexion, and stiffness to provides easier insertion.
Antimicrobial Agents
Silver is an antibacterial agent. Adding silver or another antimicrobial such as chlorhexidine, Triclosan, enzymes, nitric oxide, or liposomes to the coating reduces the risk of infection and inflammation. Antimicrobial coatings help protect from urinary tract infections (UTI) that often plaque long-term catheterization patients.
More than 75% of hospital-acquired or nosocomial urinary tract infections began by urinary catheters. These devices treated 15 to 25% of hospitalized patients. Among other purposes, urinary catheters are primarily used for draining urine after surgeries and for urinary incontinence. During catheter-associated urinary tract infections, bacteria travel up to the bladder and cause infection.23

The Cure Medical Catheter Difference
Having discussed what catheterization is, the indications for use, contraindications, construction, phthalates, and the various coating options, we will now turn to the role of Cure catheters and how they compare with the other brand offerings. Cure catheters offer significant advantages over other branded products. These advantages include PVC construction but without the use of DEHP, DINP, BPA, or natural rubber latex.
