Common indications for urinary catheterization include acute or chronic urinary retention (which can damage the kidneys) from conditions such as benign prostatic hyperplasia, orthopedic procedures that may limit a patient's movement, the need for accurate monitoring of input and output (such as in an ICU), urinary incontinence that may compromise the ability to heal wounds, and the effects of ...
When a Foley catheter becomes clogged, it must be flushed or replaced. There is currently not enough adequate evidence to conclude whether washouts are beneficial or harmful. [13] There are several risks in using a Foley catheter (or catheters generally), including: The balloon can break as the healthcare provider inserts the catheter.
The insertion of a plastic cannula and withdrawal of the needle was introduced as a technique in 1945. [11] The first disposable version to be marketed was the Angiocath, first sold in 1964. In the 1970s and 1980s, the use of plastic cannulas became routine, and their insertion was more frequently delegated to nursing staff. [12]
Intermittent catheters come in a variety of designs and differ depending on the user's genitals, with a catheter for a penis being longer and a catheter for a vulva being shorter. The catheter is inserted into the urethra by the patient or a carer and can either be directed down a toilet or, if measurement of volume is required, into a ...
Although catheter use should be minimized in all patients, particularly those at higher risk of CAUTI and mortality (e.g. the elderly or those with impaired immunity), [2] a meta analysis suggests there is insufficient evidence to determine the value of different policies for replacing long term urinary catheters on patient outcomes. [3]
Placement of a catheter into a particular part of the body may allow: Draining urine from the urinary bladder as in urinary catheterization, using intermittent catheters or Foley catheter inserted through urethra. When the urethra is damaged, suprapubic catheterisation is used instead. The suprapubic catheter is inserted through the lower part ...

Diagram of a Foley catheter. Foley first described the use of a self-retaining balloon catheter in 1929, to be used to achieve hemostasis after cystoscopic prostatectomy. [2] He worked on development of this design for use as an indwelling urinary catheter, to provide continuous drainage of the bladder, in the 1930s.
