title: Good response of low-fat/high-protein diet in a patient with chyluria.
abstract: Chyluria is an inappropriate urinary excretion of chyle that turns the urine milky. A nutritional approach based on low-fat/high-protein content diet associated or not with medium-chain triglyceride (MCT) showed to be an efficient conservative treatment to improve the milky urine appearance in a patient with chyluria.
  
  
  METHODS
  A 30-year-old female patient was admitted with chyluria of unknown etiology. An ureteropyeloscopy revealed a single lesion in each kidney, both with linear aspect and measuring 5 mm in extension. These lesions were located close to the renal papillae and were leaking a cloudy and milky fluid. Both lesions were laser cauterized followed by improvement of the milky urine. However, the chyluria relapsed after few months and a low-fat/high-protein content diet with 10 g of soybean oil to meet the requirements essential fatty acids (EFA) and with MCT from coconut oil as alternative to prepare foods was started. Few weeks later the patient returned reporting consistent improvement of the milky urine appearance related with the use of the diet. However since the diet was tasteless and time consuming to prepare, she reported low compliance to diet with MCT and the milky urine relapsed. The MCT was discontinued and the diet with EFA source was maintained with better compliance. Since then the chyluria remains in remission. In conclusion, the dramatic improvement of the milky urine with low-fat/high-protein diet with EFA source observed in our patient demonstrates that this nutritional approach is efficient with fast results to treat chyluria during long term.
