Urinothorax is a rare cause of pleural effusion and often occurs unilaterally. In a urinothorax, the pleural fluid has the color and odor of urine, and the ratio of pleural fluid creatinine to serum creatinine is greater than one. In this report, a case of urinothorax after prostate cancer is presented. The patient is a 79-year-old man with a history of BPH who presented with urinary retention, nausea, and dyspnea. Laboratory tests revealed high serum creatinine, hypercalcemia and hyperkalemia. Ultrasound revealed moderate left-sided hydronephrosis, moderate ascites and massive left-sided pleural effusion on chest X-ray. Thoracentesis and aspiration of ascitic fluid were performed, and the ratio of creatinine in pleural fluid and ascitic fluid to serum creatinine was greater than one. The patient underwent bilateral nephrostomy, after which the pleural effusion and ascites resolved without further aspiration. A prostate examination revealed an enlarged and firmer prostate than normal. The patient's PSA level was checked and found to be over 100, and a prostate biopsy diagnosed adenocarcinoma of the prostate. The patient received the first cycle of chemotherapy and was discharged from hospital in good general health.
