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 ...
[1] [2] Diagnosis is typically based on measuring the amount of urine in the bladder after urinating. [1] Treatment is typically with a catheter either through the urethra or lower abdomen. [1] [3] Other treatments may include medication to decrease the size of the prostate, urethral dilation, a urethral stent, or surgery. [1]
A Foley catheter can also be used to ripen the cervix during induction of labor. When used for this purpose, the procedure is called extra-amniotic saline infusion . [ 9 ] In this procedure, the balloon is inserted behind the cervical wall and inflated, for example with 30-80 mL of saline. [ 9 ]
Urodynamic testing or urodynamics is a study that assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests can help explain symptoms such as:
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]
Using urinary catheters as little and as short of time as possible and appropriate care of the catheter when used prevents catheter-associated urinary tract infections. [46] They should be inserted using sterile technique in hospital however non-sterile technique may be appropriate in those who self catheterize. [ 48 ]
This is a relatively rare diagnosis that is usually sparked by patients and healthcare providers noticing that a patient's urine collection bag from a catheter has become discolored and turned a purple hue. Upon visual inspection, the patient's urine is typically still clear and has no discoloration.
[8] [10] It is more common in women, in the elderly, in residents of long-term care facilities, and in people with diabetes, bladder catheters, and spinal cord injuries. [11] People with a long-term Foley catheter always show bacteriuria. Chronic asymptomatic bacteriuria occurs in as many as 50% of the population in long-term care.
