Abstract

Overview: Chyluria is a rare condition that is predominantly found in developing countries in tropical regions. The cause of the disease has been identified as the communication between the abdominal lymphatic branches and the urinary tract, but there is no documented mechanism explaining this communication. Objective: to describe the MRI radio imaging and intranodal lymphangiography in patient with chyluria to detail the hypotheses that the cause of chyluria may be the obstruction of thoracic duct. Materials and methods:  A study was conducted on 33 patients with chyluria. All patients were undergone MR lymphangiography and intranodal lymphangiography. Results: an average age of 66.1 years, with a female-to-male ratio of 2:1. The majority had communication between the lymphatic branches and the left kidney (72.7%). Magnetic resonance imaging showed a patent thoracic duct in 100% of cases, but only 84.8% showed communication with the excretory tract, while intranodal lymphangiography showed the thoracic duct in only 51.5% of cases, but all patients showed communication between the lymphatic branches and the renal pelvis. All patients had delayed lymphatic circulation, supporting the hypothesis that thoracic duct obstruction increases the pressure in the abdominal lymphatic vessels, leading to communication with the kidney as the cause of chyluria.
