Unilateral pulmonary edema after laparoscopic donor nephrectomy: report of two cases.

Unilateral pulmonary edema of the dependent lung presented after laparoscopic living-donor nephrectomy in two patients. Treatment with O(2) supplementation and diuretics resulted in relief of symptoms and radiographic improvement. The presumed causes of this previously unreported complication of laparoscopic living donor nephrectomy include prolonged lateral decubitus positioning and high fluid requirements.
