This article describes how to safely remove an indwelling urinary catheter and ensure good patient care before, during and after the procedure Show
This article, the final part of our six-part series on urinary catheters, discusses how to remove an indwelling urethral catheter, and patient care before, during and after the procedure.

Author: Ann Yates is director of continence services, Cardiff and Vale University Health Board. Urinary catheterisation is associated with a number of complications including catheter-associated urinary tract infection (CAUTI), tissue damage, and bypassing and blockage. The risk of complications means catheters should only be used after considering other continence management options, and should be removed as soon as clinically appropriate (Loveday et al, 2014). It is important to understand the reason for removal and whether the catheter is being removed permanently or in a planned or unplanned change due to problems encountered by the patient, such as a blocked catheter. The procedure differs depending on whether the insertion site is urethral or suprapubic. The removal of a urinary catheter should be a simple, uncomplicated procedure but there are recognised competencies. Nurses removing a catheter must be aware of:

Box 1. Foley catheters Foley catheters have an inflatable balloon that anchors the catheter in the bladder. The catheter has two channels – one drains urine while the other is used to inflate and deflate the balloon. Balloons are inflated with sterile water/or using liquid in syringes supplied by manufacturers. The water is usually inserted and removed using a syringe that is attached to a valve on the catheter. Balloons vary in size but adults usually require a 5-10ml balloon. Always check manufacturers’ instructions. Balloons must not be overinflated as they can rupture, leaving fragments in the bladder (Dougherty and Lister, 2015). Patient anxietyPatients may be anxious about pain and discomfort during the procedure, and about passing urine afterwards. In particular, those who have previously failed a trial without their catheter may be concerned about passing urine independently. Some may also be anxious about bladder control and urinary incontinence. These concerns may be heightened if the catheter has been in place for a long period of time. Nurses need to discuss with patients the procedure and the possible complications that can occur after catheter removal (Royal College of Nursing, 2012). They should also ensure patients know who to contact if they experience problems. Box 2 lists the complications that can occur following catheter removal.
Box 2. Complications following catheter removal Urinary retention (inability to pass urine) - Symptoms include:
If retention is suspected, it is important to perform a bladder ultrasound (Yates, 2016) and recatheterise the patient if indicated. Dysurea (pain when passing urine) - Stinging and burning may occur when passing urine; symptoms can last for a few days. It is important that patients drink 2-3L of fluids a day to dilute their urine. Frequency (need to urinate more often than usual) and urgency (sudden and compelling urge to urinate) - These symptoms can occur immediately after catheter removal. It is important that patients can reach the toilet or are supplied with appropriate aids, such as a urinal, and are able to call for assistance if required. Symptoms usually resolve in a few days but if they persist or are accompanied by signs of urinary tract infection or urinary retention, they will require further investigation. Patients with frequency and/or urgency may be reluctant to drink but should be advised that concentrated urine can irritate the bladder and cause unwanted contractions/spasms. Drinking fluids, especially water, will dilute the urine so the bladder will become less irritable and tolerate holding urine for longer periods. Haematuria (bloodstained urine) - This can occur following catheter removal but if it persists or gets worse, the patient should report it to a heath professional for further assessment. Incontinence - Patients may experience continence problems immediately after catheter removal; these may settle within a few days or take longer, depending on how long the catheter has been in situ. Patients may need management aids such as absorbent pads temporarily to help them remain dry; however, this should not be considered a long-term solution. If symptoms persist the patient should be assessed and referred for specialist support. If the catheter has been in situ for a long period of time, the patient may need bladder retraining instruction. Routine urethral catheter removalTiming of catheter removalCatheters are routinely removed early in the morning. This means that any problems, such as urinary retention, will normally present during the day and can be dealt with by appropriate health professionals (Dougherty and Lister, 2015). Equipment
