Urinary Catheter: Types, Care, and Healthcare Guidance
A urinary catheter is a narrow tube inserted into the bladder to drain urine when a person cannot urinate naturally. It is a common medical device used across healthcare settings—for surgery, bladder retention, severe incontinence, or end-of-life comfort. Understanding types, proper care, and potential risks helps patients and caregivers make informed decisions and reduce complications. This article explains how catheters work, when they are used, how they affect the bladder, and where to seek professional support or supplies in your area.
What is a urinary catheter?
A urinary catheter is a flexible tube that transports urine from the bladder to an external collection bag or directly out of the body. Common types include indwelling (Foley) catheters that remain in place, intermittent (in-and-out) catheters used periodically, and external (condom) catheters for men. Catheters are made from materials like silicone or latex; selection depends on duration of use, allergies, and clinician preference. Sizes are measured in French (Fr). As a medical device, placement and removal are performed by trained professionals or instructed caregivers to maintain safety.
How does a urinary catheter help with incontinence?
For people with severe or complex incontinence, a catheter can provide reliable urine control when other interventions fail or are impractical. Indwelling catheters manage continuous leakage, while intermittent catheterization can be part of a bladder-training or neurogenic bladder program. Catheters may also be used temporarily after surgery or during recovery. However, they are not always the first-line option because they carry risks such as infection and skin irritation. Healthcare teams evaluate individual needs, consider alternatives (absorbent products, behavioral therapies, devices), and weigh benefits against potential complications.
What precautions are needed for this medical device?
Using a urinary catheter safely requires strict attention to hygiene and technique. Handwashing, maintaining a closed drainage system, securing the catheter to prevent tugging, and keeping the collection bag below bladder level are basic precautions. Regular catheter care includes cleaning the insertion site as advised, emptying the bag frequently, and monitoring for signs of infection: fever, cloudy or foul-smelling urine, or pain. Healthcare providers schedule routine changes for indwelling catheters and train patients or caregivers on intermittent catheterization technique. Supplies and training are available through local services and home healthcare agencies.
How does a urinary catheter affect the bladder?
A catheter changes normal bladder mechanics by bypassing voluntary control and natural filling/sensation cycles. Short-term use typically causes minimal lasting effects, but long-term indwelling catheters can increase the risk of catheter-associated urinary tract infections (CAUTIs), bladder irritation, and formation of mineral encrustations. Intermittent catheterization tends to preserve bladder function better than continuous drainage because it allows periodic filling and emptying. Clinicians monitor residual urine, bladder capacity, and complications, and they revisit the need for continued catheterization regularly to prevent unnecessary bladder dysfunction.
Where to find healthcare support and supplies?
Several healthcare professionals can help with urinary catheter management: urologists, primary care clinicians, continence nurse specialists, and home health nurses. Many clinics and hospitals offer continence services or education programs. For ongoing supplies—catheters, drainage bags, securement devices—home healthcare providers, medical supply companies, and some pharmacies offer delivery or local services in your area. Telehealth appointments can be useful for follow-up questions or troubleshooting. Always confirm that suppliers and caregivers follow current clinical guidance and infection-control practices.

In summary, urinary catheters are valuable medical devices that provide necessary urine drainage in a range of clinical situations. Choosing the right type, following proper care protocols, and maintaining regular communication with healthcare providers reduce risks and support bladder health. Decisions about catheter use should be individualized, reassessed over time, and supported by trained clinicians and reliable local services.
