What is the primary function of a bladder scanner?

The primary function of a bladder scanner is to measure urine volumes and assess urinary retention. This non-invasive device uses ultrasound technology to determine the amount of urine present in the bladder, providing important information about a patient's urinary health. It is particularly useful in clinical settings for diagnosing conditions such as urinary retention, helping healthcare professionals make informed decisions regarding further interventions or treatments. The ability to quickly and accurately assess bladder volume is essential in managing patient care effectively, making bladder scanners a vital tool in many healthcare environments.

The other options pertain to different medical imaging technologies or devices: real-time imaging for procedures relates to other types of ultrasound, the creation of soft tissue images using radio waves refers to MRI machines, and regulating gas flow during surgical procedures involves anesthetic equipment. Each of these serves distinct, specialized functions unrelated to urinary volume assessment.
