A normal value is no reflux or other abnormal urine flow, and no obstruction to the flow of urine occurs. The bladder empties completely.
What abnormal results mean
Abnormal results may be due to:
- Abnormal bladder response to pressure -- could indicate a nerve problem or other disorder
Urethral obstruction-- most commonly related to an enlarged prostate gland
Vesicoureteric reflux(backflow of urine)
