urinothorax

Urinothorax (pl. urinothoraces) is defined as urine in the fluid-filled cavity that surrounds the lungs. It is usually caused by obstructive uropathy. It is mainly diagnosed by analyzing the pleural fluid. Treatment involves treating the underlying condition, which typically results in resolution of the urinothorax. It is an extremely rare cause of pleural effusion.

== Signs and symptoms == The characteristics of people affected by urinothorax are poorly defined. Urological symptoms tend to occur, while the respiratory symptoms are typically nonexistent or mild. Difficulty breathing, occurring in moderate to large pleural effusions, is the most common respiratory symptom. Other symptoms include fever, abdominal pain, chest pain, and reduced urination. It typically occurs within hours of the causative condition.
