What should be measured to assess bladder retention?

To assess bladder retention effectively, measuring the volume of urine in the bladder is crucial. This approach allows healthcare providers to determine if there is an abnormal accumulation of urine, indicating retention. When the bladder cannot empty fully, it can lead to complications such as infection, bladder distention, or damage to the bladder wall.

Measuring the volume directly gives a clear indication of urine retention, whereas other methods such as bladder pressure can provide some insights but do not quantify urine accumulation effectively. Monitoring fluid intake is important for understanding hydration status, but it does not directly indicate bladder retention. Urine color can reflect hydration and the presence of certain conditions, but it is not a direct measure of bladder retention. Thus, assessing the volume in the bladder directly answers the clinical need to evaluate whether urinary retention is present.
