Résumé
Chyluria is characterized by the presence of chyle in the urine. The most common cause of non-parasitic chyluria is the upstream obstruction of the thoracic duct and reflux of the chyle into the renal collecting system. Traditional treatments include dietary modifications and surgery. The recently developed new interventional technique to treat chyluria. Here, we firstly reported one case of chyluria caused by thoracic duct obstruction in China, which was successful treated with intranodal lymphangiography combined by percutaneous balloon plasty. The symptoms of chyluria were completely relieved after our operation, which provides a minimally invasive, safe and effective method for patients with ineffective chyluria after conservative treatment or surgery.
