[Postoperative polyuria after laparoscopic adrenalectomy for pheochromocytoma]

Disturbances of osmoregulation leading to polyuria are well known complications after operations in the sella region. In contrast, increased urinary output following adrenalectomy is rare. We report a case of postoperative polyuria after laparoscopic adrenalectomy for pheochromocytoma with urine output up to 15 l per day. Treatment included careful monitoring of the patient and intravenous and oral replacement of fluids and electrolytes. In our case a normalisation of the urine output was observed after few days. A further treatment with vasopressin was not undertaken as the osmolality at all times was in normal range.
