Bladder scanner how does it work

A simple residual bladder scan, using a scanner set up for this purpose, requires minimal technical skills but training is required to interpret the results Lehman and Owen, Although these images may reveal potentially serious bladder abnormalities - for example, stones, diverticulae, ovarian cysts and tumours - they are not intended for use as a diagnostic instrument for bladder pathology. If the scan is unclear or inconclusive, or if an abnormality is identified, the patient should be referred for further investigation.

A quality assurance programme QAP is required to ensure safe practice to protect patients and staff from misdiagnosis and malpractice. This requires a programme of training that provides basic-level skill in the use of ultrasound, leading to clinical competency. Continuing professional development is key to delivering highly effective health care and supporting clinical governance. Bladder scanning courses run by local specialists are recommended as a minimum training requirement.

Healthcare professionals should have medical indemnity insurance; this is usually provided by their professional body. All employers must provide liability insurance for all staff for practice in any clinical environment. A comprehensive insurance cover for the scanner and transducers should also be in place in case of damage or theft. Equipment should be treated with care and stored safely.

The battery should always be charged and care should be taken to avoid overheating the scanner or the probe. A maintenance programme should be in place with the manufacturers. Scanners should be checked and calibrated regularly. Contingency plans must be in place in case a scanner is out of commission because of servicing, recalibration or an unforeseen fault.

Nurses should not be afraid to use an ultrasound scanner but instead consider whether its use enhances the care they can provide see Box 1. There is a view that bladder ultrasound requires a high level of expertise. This is not the case as long as clinicians are well trained. Real-time images are easy to interpret and provide valuable results. This evolving technology represents a significant challenge to the nursing profession and we need to ensure we are well trained and supervised to implement the change in practice.

Urethral catheterisation has been superseded by ultrasound scanning of the bladder and there is strong evidence to recommend its use as an alternative to catheterisation Choe et al, Alivizatos, G. International Journal of Urology ; 11; 12, Choe, J.

Fedorkow, D. Journal of Obstetrics and Gynaecology Canada; 10, Gilbert, R. Nursing Times; 2, Lehman, C. SCI Nursing ; 2, Martin, J. Neurourology and Urodynamics ; , Mathew, S. Journal of Obstetrics and Gynaecology; 6, After the urethra is cleaned, a thin, flexible tube called a catheter is placed through and into the bladder.

The liquid with radioactive material is moved through the tube to fill the bladder and you feel the fullness. The bladder is then scanned, and images are taken of the bladder and kidneys.

You may also be asked to urinate during the test. You may have some pain when the catheter is used. There is also a small chance of a urinary tract infection as with any use of a catheter. You may feel some pain when you urinate for a few hours after the test. Category: FutureLearn Local , Learning.

A post void bladder scan is a non-invasive method of assessing bladder volume using ultrasonography and should be undertaken on first contact with all individuals with consent. Clinical Practice Point. Remember that some individuals can present with a normal voiding pattern but have a significant post void residual.

A delay could result in the individual suffering long term bladder damage with potential associated complications. If residual urine is found in the bladder discuss this with the individual, request them to try to void again and re-scan. If the PVR is between ml give advice to promote more effective bladder emptying — sit down with feet well supported, take time, lean forward, use double voiding.
