Bladder Scanning
Non-invasive bladder volume assessment to check urine retention and ensure optimal post-catheterisation bladder function.
Bladder scanning is a non-invasive ultrasound test that measures the amount of urine left in the bladder after you pass urine (post-void residual). It helps assess how well the bladder is emptying and guides further care decisions.
Symptoms of incomplete emptying (urgency, weak stream, dribbling).
After catheter removal to check bladder function.
For monitoring patients with bladder dysfunction or long-term catheters.
During a trial without catheter (TWOC) to prevent bladder over-distension.
A trained nurse places a small probe over your lower abdomen using ultrasound gel.
You may be asked to void first, then be scanned to measure remaining urine.
The scan is quick, painless, and avoids invasive catheter measures when possible.
Results inform whether monitoring, further intervention, or no action is needed.
Reduces unnecessary catheterisations and their risks.
Provides clear, objective measurements to guide your care.
Offers reassurance and helps plan appropriate next steps.
High residual volumes may indicate retention and require further assessment.
Certain factors (for example, obesity or prior abdominal surgery) can affect scan accuracy.
