Although pleural effusion is indicative of an intrathoracic problem, it can also result from a number of extrathoracic cause, such as hypoproteinemia, Meig's syndrome, pancreatitis, urinothorax. Urinothorax is a rare cause of pleural effusion secondary to obstructive uropathy or a leakage from the urinary tract. Urinoma, retroperitoneal inflammatory or malignant diseases, renal biopsy, blunt trauma, percutaneous renal and endoscopic ureteral intervention are the reported causes of urinothorax. It is believed that the urine moves retroperitoneally into the pleural space, and the effusion resolves quickly with removal of the obstruction. Pleural fluid smells like urine, pleural fluid's biochemical characteristics, and renal scan can aid the diagnosis of urinothorax. Most cases are diagnosed retrospectively, that is when pleural effusion resolves following urinary diversion.
I report a case of urinothorax due to a leakage from the urinary tract in a cervical cancer patient. She had right sided pleural effusion which demonstrated as urinothorax. The effusion disappeared within a few days after urinary drainage had been established.
