Description
Disturbances in sodium and water balance are common following pituitary surgery. Accurate, repeated assessments of fluid balance and electrolytes are vital to avoid preventable complications. Shorter in-patient stays following surgery mean such assessments may be difficult and incomplete. We present a patient who developed cranial diabetes insipidus following transfrontal resection of a pituitary adenoma in whom the problem was only detected when he presented in urinary retention.
