Virtsakatetoinnissa

Virtsakatetointi, also known as urinary catheterization, is a medical procedure involving the insertion of a tube, called a catheter, through the urethra into the bladder. This allows urine to drain from the bladder. It is a common procedure performed in various healthcare settings, including hospitals, clinics, and even at home under medical guidance.

The primary indications for urinary catheterization include the inability to urinate naturally due to conditions like bladder outlet obstruction, urinary retention, or neurological issues affecting bladder control. It is also used to monitor urine output accurately in critically ill patients, to empty the bladder before or after surgery, and to obtain a sterile urine sample for diagnostic testing.

There are different types of urinary catheters, with the most common being the Foley catheter, which is a self-retaining catheter held in place by a balloon inflated within the bladder. Intermittent catheters are designed for single use, inserted to drain the bladder and then removed. Indwelling catheters remain in the bladder for extended periods, typically connected to a drainage bag.

While generally safe, urinary catheterization carries potential risks, including urinary tract infections (UTIs), bladder spasms, discomfort, and, less commonly, trauma to the urethra. Proper sterile technique during insertion and diligent care of the catheter and drainage system are crucial to minimize these risks. The duration of catheterization depends on the underlying medical reason, and removal is typically performed as soon as it is no longer medically necessary.
