Polyuria is a condition of excessive production of urine. Polyuria may be defined as an output exceeding 3 l/day in adults and 2 l/m2/day in children. This definition is not entirely adequate for the perioperative period, since it is often necessary to recognize and treat polyuria before 24 hours of urine has been collected. Although no single definition of perioperative polyuria has been universally accepted, urine output exceeding 4 to 5 ml/kg/hr is excessive. The differential diagnosis of polyuria is unique after surgery and relatively narrow.
