Urinothorax: A rare cause of severe respiratory distress.

A case of massive right pleural effusion in a postoperative patient of percutaneous nephrolithotomy leading to severe respiratory distress is reported. A high degree of clinical suspicion and prompt intervention by insertion of an intercostal drainage tube prevented the patient from going in to respiratory failure. The development of arrhythmias confused the picture increasing the morbidity of the patient.
