Unilateral dependant pulmonary edema during laparoscopic donor nephrectomy: report of three cases.

Unilateral pulmonary edema of the dependant lung was observed in three patients during laparoscopic donor nephrectomy. Patients were treated with O2 supplementation by face mask, fluid restriction and diuretic. All the patients were relieved of symptoms with radiological improvement. The possible causes of this unusual complication following laparoscopic surgery appear to be prolonged lateral decubitus position and high intraoperative fluid infusion.
