Uroflowmetry is the most reliable initial test for evaluating lower urinary tract obstruction, helping avoid misdiagnosis and unnecessary treatments. Other methods like symptomatology have interpretative limits.

Area of Science:

  • Urology
  • Diagnostic Imaging

Background:

  • Lower urinary tract obstruction (LUTO) evaluation relies on multiple parameters.
  • Current methods include symptomatology, post-micturition residual urine, bladder trabeculation, and uroflowmetry.
  • Each parameter presents unique interpretative limitations.

Purpose of the Study:

  • To critically review accredited parameters for assessing lower urinary tract obstruction.
  • To identify the most reliable diagnostic tool for suspected infravesical obstruction.

Main Methods:

  • Critical review of existing literature and clinical data.
  • Comparative analysis of diagnostic accuracy for various LUTO parameters.

Main Results:

  • Symptomatology, post-micturition residual urine, and bladder trabeculation show interpretative limits.

  • Uroflowmetry is identified as the most reliable parameter for initial LUTO assessment.
  • Uroflowmetry effectively identifies equivocal cases requiring further investigation.

    • Conclusions:

    • Uroflowmetry should be the first diagnostic step for suspected infravesical obstruction.
    • Pressure-flow studies are valuable for confirming equivocal findings from uroflowmetry.
    • Utilizing uroflowmetry first helps prevent false-positive diagnoses and inappropriate therapies.
