Metal catheters are no longer widely used for females due to the discomfort and potential risks associated with them. However, they may still be used in specific surgical procedures.
 
Here are some details about metal catheters:
Material: Typically made from high-quality stainless steel.
Reusable: They can be sterilized and reused multiple times.
Disadvantages:
Can be uncomfortable to insert and wear.
Increase the risk of urethral irritation and infection.
For routine urinary drainage, soft, flexible catheters made of silicone or latex are preferred because they are much more comfortable and have a lower risk of complications.
If you are looking for information on catheters for urinary drainage, it is recommended to consult with a doctor or search for information on soft, flexible catheters.
