• Urinothorax
• Pleural effusion
• Renal biopsy

Background: Urinothorax is defined as the presence of urine in the pleural space and is a rather rare cause of transudate pleural effusion. The potential etiologies are urinary tract obstruction and trauma. Diagnosis requires a high index of clinical suspicion and the condition is completely reversible following relief of underlying disease.
Case presentation: We report a 27-year-old man who developed urinothorax after renal biopsy. Urine leakage was confirmed with (99)mTc DTPA (diethylenetriaminepentacetate) and single-photon emission computed tomography scans and retrograde pyelography. The pleural effusion was completely resolved by removing the leakage with a Foley catheter and a double J stent.
Conclusions: Urinothorax has not been reported in patients doing renal biopsy in the literature. Based on our experience, urinothorax should be suspected, diagnosed, and managed appropriately when pleural effusion occurred after renal biopsy.
