Urinothorax: An uncommon case of pleural effusion

Urinothorax is classically described as the formation of urinoma as a result of retroperitoneal leakage and accumulation of urine in the pleural cavity. Since respiratory manifestations could be uncommon or rare and dominated by urological signs, which could be due to secondary or obstructive uropathy; the diagnosis of urinothorax warrants high clinical suspicion. We report such an uncommon case of urinothorax in a patient with chronic kidney disease admitted to a tertiary industrial hospital and treated successfully. Increased awareness among the physicians of such a rare clinical entity may facilitate prompt diagnosis and appropriate clinical management.
