What are appropriate indications for using indwelling urinary catheters?

Using indwelling urinary catheters, also known as Foley catheters, is appropriate in certain clinical circumstances. One clear indication is managing acute urinary retention, which is when a patient cannot voluntarily urinate, potentially leading to pain, bladder distension, or further complications. In this case, a catheter can help relieve the retained urine and prevent bladder damage or infection.

While managing prolonged immobilization could be a valid reason for catheter use, it is important to consider that this is not universally endorsed, as it can increase the risk of urinary tract infections (UTIs) and other complications. Routine urinary samples for all residents are not appropriate, as catheters should only be used when necessary, considering the associated risks. Similarly, using catheters for managing urinary incontinence, particularly in the elderly, is generally discouraged unless other treatment options are unsuitable, as it can contribute to increased UTI risk and other issues.

In summary, the appropriate use of indwelling urinary catheters is specifically indicated for managing acute urinary retention, highlighting the need for careful consideration of the risks versus the benefits in clinical practice.
