Lipiduria after intralipid infusion of a lipid emulsion in a boy with an abdominal trauma.

A 4-year-old boy with an abdominal trauma had lipiduria following treatment with total intravenous nutrition for 4 days. Renal function was normal throughout the course and the lipiduria ceased after withdrawal of the intravenous nutrition. The lipids were possibly excreted through the kidneys or entered the urine through a traumatic communication between the lymphatic vessels and the urinary system. Control of renal function and lipiduria after 1 year revealed normal conditions.
