Urinothorax (pl. urinothoraces) means urine in the fluid-filled cavity that surrounds the lungs.[1] It is a rare cause of pleural effusion secondary to obstructive uropathy whereby urine forms a collection in the pleural cavity. The urine arrives in the pleural space either retroperitoneally under the posterior diaphragm, or via the retroperitoneal lymphatics. It remains a rare, possibly under-diagnosed, differential in the case of transudative pleural effusion. Respiratory symptoms are usually mild.[2] Handa et al.,[3] described 47 cases between 1967 and 2007, noting that it was more prevalent in males, generally ipsilateral to the obstruction, and in most of the cases it is relieved by clearance of the obstruction.

Symptoms[edit]

Symptoms include difficulty breathing, abdominal pain, chest pain, and reduced urination.[4]
