A catheter placed through the urethra and into the bladder can show how much urine remains in the bladder after the patient urinates--a measure of how severe the obstruction is.
Typically you would have to start the 24 hr urine test over unless it was a very scant amount of urine that was missed. If you voided and forgot to measure, you'd have to start over.
