katétru

Katétru is a term that appears to be a misspelling or a less common variation of "catheter." A catheter is a medical device that is typically a thin, flexible tube inserted into a body cavity, duct, or vessel to withdraw fluids or introduce fluids.

The most common uses of catheters involve the urinary tract. A urinary catheter is used to drain the bladder when a person is unable to do so on their own, often due to medical conditions like urinary retention, prostate enlargement, or during surgical procedures. These can be inserted through the urethra or surgically placed through the abdominal wall.

Beyond urinary applications, catheters are also used in various other medical fields. In cardiovascular medicine, catheters are crucial for procedures like angioplasty and stenting, where they are guided through blood vessels to open blockages or deliver medication. They can also be used for diagnostic purposes, such as measuring pressure within certain vessels.

Other applications include gastrointestinal catheters for feeding or draining the stomach, and epidural catheters for pain management during labor or surgery. The material of a catheter varies depending on its intended use, but is typically made of medical-grade silicone, rubber, or plastic to ensure biocompatibility and flexibility. Proper insertion and maintenance are vital to prevent infection and complications.
