Careful hygiene is essential to prevent urinary tract infections and other complications associated with long-term catheter use.
Foley catheters are often used in hospitalized patients, those undergoing surgeries, or individuals with specific medical needs.

Intermittent Catheters:

Intermittent catheterization involves inserting a catheter into the bladder to drain urine when needed, and then removing it.
These catheters are typically used for short-term purposes, such as when patients have difficulty urinating or need to manage urinary retention.
Intermittent catheterization is performed at regular intervals, ensuring the bladder does not become overly distended.
This method helps reduce the risk of infection compared to indwelling catheters and is more suitable for patients who can learn and perform the procedure themselves.
Intermittent catheters are available in various lengths, materials, and types, including closed systems that minimize the risk of contamination.

Urinary catheters are used in various clinical scenarios.

Post-Surgery: After certain surgeries, patients may have difficulty urinating due to anesthesia or other factors. Catheters help prevent urinary retention and maintain bladder function.
Urinary Incontinence: For patients with urinary incontinence, indwelling catheters can help manage constant leakage of urine.
Urinary Retention: Individuals with conditions such as prostate enlargement or neurological disorders may experience difficulty emptying their bladder. Catheters can ensure complete drainage.
Chronic Medical Conditions: Patients with conditions like spinal cord injuries, multiple sclerosis, or certain neurological disorders may require long-term urinary catheterization.
Monitoring Output: In critical care settings, urinary catheters help monitor urine output to assess kidney function and fluid balance.
Patient Convenience: Some patients prefer intermittent catheterization because it allows them to control the timing of bladder emptying and reduces the need for a permanent catheter.

Central Venous Catheters (CVCs):

Types of Central Venous Catheters.

Peripherally Inserted Central Catheters (PICCs):
