Urine flow study is a diagnostic procedure to evaluate the rate of urine flow when a patient voluntarily empties the bladder (voids).
- History of urethral stricture
- Prior surgery on the prostate or urethra Procedure
- Difficult or incomplete bladder emptying
In a procedure room, the patient either sits or stands (depending upon his or her usual voiding habit) over a special measuring device and voids into a container just as he or she normally would at home. The device then measures the amount voided and how long this takes. The urine flow rate is then calculated, and the urine that remains in the bladder is measured.
