Has not passed urine. But is the bladder full?

Is bladder volume of concern to the perioperative team when the patient is undergoing a procedure not related to the same anatomical area? A common scenario is that the patient is requested to void prior to leaving the ward and their word taken that they have done so. The patient then enters the theatre environment and the only time that urinary function is taken into account is if the blood pressure falls and kidney function needs to be monitored.
