Blocked urinary catheters: can they be better managed?

The role of the district nurse in managing blocked urinary catheters

This article will investigate the district nurse's role in managing urinary catheter blockages, looking at why people require long-term catheterisation and the causes of blockages and then reviewing treatment methods. Current practice will be critically analysed and compared to the most up to date research and literature to inform district nurses of best evidence-based practice in the hopes of improving service user outcomes and quality of life and reducing the impact this problem has upon district nursing services with regards to time and resources.

Use of indwelling catheters and preventing catheter-associated urinary tract infections

Indwelling urinary catheters are considered an important healthcare intervention for many patients. However, these devices must be used with caution because they are associated with a risk of various potential complications such as catheter-associated urinary tract infections (CAUTIs), as well as a financial burden for healthcare organisations. This article outlines the various types of indwelling catheter that are available, explains the reasons for their use, and details the care required to prevent associated complications, particularly CAUTIs.

British Association of Urological Surgeons (BAUS) and Nurses (BAUN) consensus document: management of the complications of long-term indwelling catheters

OBJECTIVE

To look at best evidence and expert opinion to provide advice in the form of a consensus statement lead by Female, Neurological and Urodynamic Urology (FNUU) section of the British Association of Urological Surgeons (BAUS) in conjunction with the British Association of Urological Nurses (BAUN).

METHODS

Initially a literature search was performed with incorporation of aspects of the existing guidance and further informed by UK best practice by core members of the group. The document then underwent reviews by the FNUU Executive Committee members, the BAUN executive committee, a separate experienced urologist and presented at the BAUS annual meeting 2020 to ensure wider feedback was incorporated in the document.

RESULTS

Complications of long-term indwelling catheters include catheter-associated urinary tract infections (CAUTI), purple urine bag syndrome, catheter blockages, bladder spasms (causing pain and urinary leakage), loss of bladder capacity, urethral erosion ("catheter hypospadias")/dilatation of bladder outlet and chronic inflammation (metaplasia and cancer risk).

CONCLUSIONS

We have provided a list of recommendations and a troubleshooting table to help with the management of the complications of long term catheters.

Care of patients undergoing removal of an indwelling urinary catheter

An indwelling urinary (Foley) catheter may be used in the management of various urological conditions, such as intractable incontinence and urinary retention, or as part of treatment regimens such as chemotherapy. Although some catheters may be required for long-term use, healthcare practitioners should regularly assess whether the device is still necessary and if it can be removed. This is because urinary catheters are a highly invasive intervention and their use is associated with a range of potential complications, including healthcare-associated infection and trauma to the neck of the bladder. This article outlines the procedure for the safe removal of a urinary catheter, including the patient care and monitoring required before, during and after this procedure. It also explains the complications that are associated with catheter removal and how these can be prevented and managed.

Managing complications associated with the use of indwelling urinary catheters

The insertion of an indwelling urethral urinary catheter is an invasive procedure that is commonly undertaken in healthcare settings. However, there are several risks and potential complications associated with these devices, so their use should be avoided where possible. It is important that nurses are equipped with the necessary knowledge and skills not only to assess if a patient requires a catheter, but also to minimise the risk of associated complications and to understand how these can be managed. This article discusses some of the common complications that can occur with the use of indwelling urinary catheters, including: catheter-associated urinary tract infections; catheter blockages; encrustation; negative pressure; bladder spasm and trauma; and, in men, paraphimosis. It also explains the steps that nurses can take to reduce the risk of these complications and how to manage them effectively.

Prevention and management of urinary catheter blockages in community settings

Self-management of long-term urinary catheters can be challenging for patients, and recurrent catheter blockages may cause concern among patients, carers and healthcare professionals. Catheter blockages are a significant challenge for nurses practising in community settings, because frequent and unplanned catheter changes can be costly to healthcare services in terms of time and resources. This article details evidence-based recommendations for the assessment and diagnosis of catheter blockages, as well as the identification of risk factors. It also explains the interventions that can be used to prevent and manage catheter blockages and describes the role of the nurse in supporting patients with a long-term catheter in situ in community settings.
