To discuss the role of direct lymphangiography in the diagnosis of primary chyluria.


Iodized oil was infused into lymphatic vessel of unilateral foot in 25 cases. The condition of lymphatic system imaging was dynamically observed via Innova 2100-IQ digital flat-panel angiography system.


All of them underwent direct lymphangiography. The results revealed unilateral (n = 18) or bilateral (n = 7) renal reflux of contrast media. Among 22 stenotic cases, there were partial (n = 18) or whole (n = 4) cervical section of thoracic duct, no imaging in cervicothoracic section of thoracic duct (n = 1); thin imaging in cervical section and partial thoracic section (n = 2); retroperitoneal lymphangictasia & tortuous lymphatic vessels (n = 21); reflux of contrast medium to pelvic and/or contralateral sacroiliac part (n = 13).


Capable of acquiring dynamic images of chyle (lymph) circulation, direct lymphangiography provides accurate estimation for the location, scope, extent of lesions of renal chylous reflux in primary chyluria so as to guide surgery. Stenotic cervical section of thoracic duct plays an important etiologic role in primary chyluria.
