title: Urinothorax: a rare finding after urinary intervention.
abstract: BACKGROUND
  We report a case in our center of unilateral urinothorax that occurred post percutaneous nephrolithotomy as a rare cause of pleural effusion and acute dyspnea.
  
  
  METHODS
  Report of a case.
  
  
  RESULTS
  Initial chest CT showed massive left sided pleural effusion from which biochemical investigations revealed exudative effusion and urinothorax. The effusion was drained by central venous pressure catheter and urologic problem was resolved.
  
  
  CONCLUSIONS
  urinothorax should be suspected as a cause of pleural effusion in obstructive uropathy and post renal and ureteric maneuvers.
