    This study explored using ultrasound to measure post-void residual urine, offering a more comfortable alternative to catheterization for assessing bladder emptying function.

    Area of Science:

    • Urology
    • Medical Imaging

    Background:

    • Bladder emptying function is crucial for urinary health.
    • Traditional post-void residual urine measurement via transurethral catheterization can be uncomfortable for patients.
    • There is a need for non-invasive and patient-friendly methods to assess bladder emptying.

    Purpose of the Study:

    • To evaluate the utility of combined uroflowmetry and transabdominal ultrasound scanning for assessing bladder emptying function.
    • To determine if ultrasound can reliably detect post-void residual urine in patients with dysuria.

    Main Methods:

    • Seven patients with dysuria underwent combined uroflowmetry and sector transabdominal ultrasound scanning.
    • Post-void residual urine volume was detected and estimated using ultrasound.
    • Bladder volume estimation assumed an ellipsoidal shape.

    Main Results:

    • Detection of post-void residual urine was successful in all seven patients.
    • While volume estimation accuracy was limited by the ellipsoidal assumption, the method proved effective for detection.
    • The combined approach demonstrated feasibility for evaluating bladder emptying.

    Conclusions:

    • Combined uroflowmetry and transabdominal ultrasound scanning is a useful, non-invasive method for evaluating bladder emptying function.
    • This technique offers a more patient-accepted alternative to transurethral catheterization for post-void residual urine measurement.
    • Further refinement of ultrasound-based volume estimation could enhance its diagnostic accuracy.
