Uroflowmetry measures the flow of urine. It tracks how fast urine flows, how much flows out, and how long it takes. It’s a diagnostic test to assess how well the urinary tract functions. Your doctor may suggest uroflowmetry if you have trouble urinating, or have a slow stream.
By measuring the average and top rates of urine flow, this test can show an obstruction in your urinary tract such as an enlarged prostate. When combined with the cystometrogram (CMG) it can help find problems like a weak bladder.
