One hundred patients with chyluria were studied with lymphography and 80 cases were followed up for a period varying between six months to two and one half years. 2. There was preponderance of left sided lesions. The site of fistulations were mostly in the region of pelvis and calyces of the kidney. 3. It was observed that lymphography was very useful in treatment of chyluria. Thirty-eight patients (48%) with chyluria were completely free from symptoms and after lymphography, 23 (28%) of them had relief and 19 (24%) of the patients did not have any beneficial effect after lymphography. This procedure was of great help in demonstrating the site of fistulations which could be surgically corrected, in certain situations. 4. Lymphographic appearances of thoracic duct was helpful in deciding the operation of thoracic duct jugular vein anastomosis in some cases. 5. Lymphatico venous anastomosis was done in 3 patients at the root of the scrotum in whom retrograde flow of contrast material occurred into the testicular lymphatics on lymphography.
