Abnormal deviation in the measurement of residual urine volume using a portable ultrasound bladder scanner: a case report

In addition to being suitable for the assessment of residual urine volume, the use of a portable bladder scanner can also assist medical staff in developing a reasonable urination plan. Portable scanners can help medical personnel to estimate the height and/or relaxation of the bladder neck for pelvic floor muscle training, assist in the efficacy evaluation of muscarinic antagonists in patients with neurogenic detrusor overactivity, and even determine whether the urine in the bladder of pediatric patients meets the criteria for catheterization to obtain urine samples. However, in the case described herein, we encountered abnormal deviation between the data measured by a portal bladder scanner and actual catheterization. The patient was a 65-year-old male suffering spinal nerve dysfunction due to tuberculous meningitis. He had functional dysuria and a history of liver cirrhosis, accompanied by a large amount of ascites. We therefore deduced that the deviation in the scanning data was attributable to the ascites. After the patient’s ascites had resolved, the residual urine volume obtained via scanning evaluation was comparable to that obtained through catheterization. Our case shows that in the event of abnormal deviation in portable bladder scanner measurements, clinical judgements should be made based on the patient’s condition rather than the scanning results alone.

Preventing catheter-related problems in community settings

Catheter-associated bladder pain: it's not always infection

This article is a case study examining the diagnosis and management of bladder dysfunction and catheter-associated pain in an older woman with diabetes and a hypotonic bladder. The incidence of diabetes has reached epidemic proportions. Although people with diabetes frequently develop lower urinary tract symptoms and voiding difficulties, this is often an unrecognised problem. As the incidence of diabetes grows, the incidence of diabetes-related bladder dysfunction will also increase. It is important that community nurses are aware of how diabetes affects bladder function and how to enable people with diabetes to manage bladder dysfunction well.

The effects of a catheter clamping protocol on bladder function in neurosurgical patients: a controlled trial

There is scant evidence-based literature on the best strategies for short-term urinary catheter removal. This clinical trial explored the effects of an early urinary catheter clamping protocol on bladder function in neurosurgical patients. Eligible patients were divided into observation and control groups. Those in the observation group had their catheter clamped postoperatively on return to the ward and unclamped at dedicated intervals. The control group received standard care; the catheter was on free drainage during the entire time in situ. The mean catheter indwelling time was 2.6 days. Compared with the control group, the observation group experienced shorter time to first postoperative urination, less residual urine volume and better subjective perception during their first postoperative urination. For patients undergoing neurosurgery and associated short-term indwelling urinary catheterization, an early catheter clamping protocol is effective in facilitating bladder function, reducing the rate of dysuria and making patients feel more comfortable after catheter removal.

Sacral region massage as an alternative to the urinary catheter used to prevent urinary retention after cesarean delivery

OBJECTIVE

The aim of the study was to determine the effect of massage to the sacral region after cesarean delivery instead of employing a urinary catheter for the prevention of urinary retention.

STUDY DESIGN

Cross sectional study.

MATERIAL AND METHODS

This interventional study population consisted of 60 women who were divided into two intervention groups and one control group. For the first intervention group, the sacral region was massaged every hour 10-15 minutes after cesarean delivery and every 30 minutes after a voiding sensation for the second intervention group. No interventions were made in the control group, although routine hospital services were provided. Socio-demographic data were collected using a questionnaire developed by the researchers. Other data were collected via observation.

RESULTS

Fifteen percent (15%) of the women in the first intervention group needed to void 2 hours after cesarean delivery, 35% after 3 hours, and the mean time to void after delivery was 3.4±0.8 hours. Forty percent (40%) of the women in the second intervention group needed to void after 5 hours, and the mean time to void after delivery was 5.5±0.8 hours. Sixty percent (60%) of the women in the control group needed to void 6 hours later, and the mean time to void after delivery was 6.2±0.7 hours. Urinary retention was not observed in the first intervention group. Our statistical analysis showed a significant difference between the three groups in terms of mean times to void after cesarean delivery (p<0.05).

CONCLUSION

In order to facilitate voiding and to prevent urinary retention, which is seen as a post-cesarean complication, massaging the sacral region could be recommended instead of urinary catheter insertion. Additional studies with larger groups are also recommended.

Urinary incontinence: providing respectful, dignified care

People are living longer than ever before and ageing and illness associated with ageing can affect a person's ability to remain continent. In many cases, the older person can benefit from rehabilitation and continence promotion. In some cases, this is not possible and the nurse's role is to work with the older person to help the person manage continence problems. It is vital that nurses work with individuals to provide person-centred continence care. This paper examines some of the difficulties older people can experience and how the nurse can enable the individual to have the best possible quality of life.

Intermittent self-catheterisation: past, present and future

In the past, the only way to drain a bladder was to use intermittent catheterisation. For four millennia, intermittent self-catheterisation (ISC) was used to treat bladder dysfunction. That changed in the 20th century when Foley redesigned and improved on 19th century designs for an indwelling urethral catheter. While some patients benefit from indwelling catheters, long- and short-term indwelling catheters can increase infection risks and contribute to bladder dysfunction. NICE guidance on infection control recommends that intermittent catheterisation should be used in preference to an indwelling catheter if it is a clinically appropriate and practical option for the patient. NICE also recommends that patients should be offered a choice of either single-use hydrophilic or gel reservoir catheters for intermittent self-catheterisation. Voiding problems increase the risks of infection, bladder and renal dysfunction, and can impair quality of life. Individuals who have reasonable bladder capacity and sufficient dexterity and motivation can regain bladder control using ISC, which can make a huge difference to their health and wellbeing.

Should antibiotics be prescribed when urinary catheters are removed?

Each year around one million urinary catheters are inserted in NHS hospitals. In around 60% of cases prophylactic antibiotics are prescribed prior to removal. This practice aims to reduce infection risks, but is not supported by evidence. Inappropriate prescribing increases antibiotic resistance, already a serious and worsening problem, and exposes patients to the hazards of antibiotic prescribing. This practice also costs an estimated £1.35-£2.7 million pounds annually. Nurses at all levels can have a huge influence on catherterization rates and catheter management. This can reduce the risks of harm and infection and improve quality of care.

Preventing infection with long-term indwelling urinary catheters

This article sets out to inform readers on the care and management of indwelling catheters. The reason for urinary catheter insertion is discussed and the decision to use a long-term indwelling urinary catheter is explained. This article focuses on the risk of urinary tract infections (UTI) associated with the use of long-term indwelling catheters and how these may be avoided. Examples of current products are detailed and how the selection of the right product may be achieved is also outlined.
