Uroflowmetry is a noninvasive diagnostic screening that calculates the flow rate of urine to assess bladder and sphincter function.

What Does Uroflowmetry Involve?

For this test, a patient urinates into a special receptacle that measures the amount and flow rate of urine and time required to completely void their bladder. These assessments can help doctors evaluate how well the lower urinary tract is functioning or identify any obstruction of urine flow.

What Other Tests Are Typically Done With Uroflowmetry?

Uroflowmetry is often used with other tests to diagnose obstructed urinary outflow or urinary tract dysfunction, including:

  • Cystometry
  • Cystography
  • Retrograde cystography
  • Cystoscopy

What Conditions Can Uroflowmetry Help Diagnose?

Uroflowmetry provides valuable feedback about lower urinary tract health. It can be helpful with diagnosing a number of urologic conditions, including:

  • Benign prostatic hypertrophy (BPH)
  • Prostate cancer
  • Bladder cancer
  • Incontinence
  • Urinary obstruction 
  • Neurogenic bladder dysfunction
  • Urinary Tract Infections (UTIs)
