An accurate and early diagnosis is crucial as resolution of the underlying pathology is the mainstay of treatment. We report the case of a 69-year-old man who was admitted to the Internal Medicine ward due to obstructive acute kidney injury of unknown origin. The patient was submitted to urinary catheterization and to right percutaneous nephrostomy. Two weeks after admission he developed a large left pleural effusion; a left urinoma was also visible on computed tomography. After thoracentesis, pleural fluid analysis demonstrated a paucicellular transudate with pH &lt;7.40 and pleural fluid\/serum creatinine ratio &gt;1.0. The diagnosis of urinothorax was made and further study allowed the diagnosis of prostate cancer as the aetiology of the obstruction. When bilateral percutaneous nephrostomy was performed, resolution of the urinothorax and normalization of renal function occurred.<\/jats:p>","DOI":"10.12890\/2020_001865","type":"journal-article","created":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T09:52:37Z","timestamp":1621936357000},"source":"Crossref","is-referenced-by-count":1,"title":["Pleural Effusion Secondary to Obstructive Uropathy: A Case of Urinothorax"],"prefix":"10.12890","volume":"7","author":[{"given":"Andreia","family":"Freitas","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Centro Hospitalar Vila Nova de Gaia\/Espinho, Vila Nova de Gaia, Portugal"}]},{"given":"Telmo","family":"Coelho","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Centro Hospitalar Vila Nova de Gaia\/Espinho, Vila Nova de Gaia, Portugal"}]},{"given":"Sara","family":"Be\u00e7a","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Centro Hospitalar Vila Nova de Gaia\/Espinho, Vila Nova de Gaia, Portugal"}]},{"given":"Tiago","family":"Greg\u00f3rio","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Centro Hospitalar Vila Nova de Gaia\/Espinho, Vila Nova de Gaia, Portugal"}]}],"member":"10397","published-online":{"date-parts":[[2020,9,16]]},"reference":[{"key":"10.12890\/2020_001865_ref1","doi-asserted-by":"crossref","unstructured":"<li>Kelley M, Spieler B, Rouse C, Karl B, Marshall R, Carbonella G.
