Urinothorax: A rare complication of spontaneous bladder rupture

Urinothorax (UT) is an uncommon cause of pleural effusion where urine collects in the pleural cavity that is usually caused by trauma or urinary obstruction. Spontaneous bladder rupture is another rare condition that is commonly caused by underlying bladder wall pathology and exacerbated by binge alcohol consumption, malignancy, autoimmune disorders, radiation, and obstructive or neurogenic pathology. We present a case of urinothorax caused by spontaneous bladder rupture in an adult patient successfully recognized and treated.
