What advantage does using a bladder scanner provide in medical practice?

Using a bladder scanner provides the significant advantage of reducing unnecessary catheterization. This non-invasive tool allows healthcare professionals to accurately measure the volume of urine in the bladder without the need for inserting a catheter. By obtaining precise measurements, it helps determine whether a patient truly needs catheterization, effectively minimizing the risks and discomfort associated with the procedure, such as urinary tract infections or bladder irritation. This approach aligns with best practices in patient care by promoting comfort and reducing potential complications.

The other options focus on imaging techniques associated with different medical practices. They involve imaging modalities better suited for diagnostic imaging or surgical contexts, which are not the primary functions of a bladder scanner. Thus, the bladder scanner's main benefit lies in preventing unnecessary procedures through accurate assessment of bladder volume.
