Urinothorax (pl. urinothoraces) is defined as urine in the fluid-filled cavity that surrounds the lungs.[1] It is usually caused by obstructive uropathy. It is mainly diagnosed by analyzing the pleural fluid. Treatment involves treating the underlying condition, which typically results in resolution of the urinothorax. It is an extremely rare cause of pleural effusion.[2]
