Urinothorax Following Blunt Trauma to the Kidney

An unusual cause of pleural effusion, urinothorax in a child with urinary stone disease

“…In this case, abdominal USG showing obstructive hydronephrosis, urinoma and elevated urea nitrogen of the pleural fluid confirmed the diagnosis, so we did not need these invasive procedures. We think that renal calculi resulted in obstructive uropathy in the present case [1,2,5,7].…”

“…Urinothorax is known to be a manifestation of retroperitoneal urinary leakage and may be secondary to urinary obstruction, trauma, retroperitoneal inflammation or malignant diseases or after surgical procedures that may cause a fistula between kidney and pleural space [1,2,4,5]. Urinothorax develops in the affected obstructed side [2].…”

“…Lahiry et al have described lymphatic drainage as the cause of pleural effusion after abdominal trauma [5]. Oguzulgen et al reported a patient with urinothorax who underwent extracorporeal shockwave lithotripsy for nephrolithiasis [7].…”

Bilateral perirenal urinoma with mediastinal extension

“…Although a limitation of superior borders of perirenal spaces by the diaphragm is widely accepted, intrathoracic extension of perirenal urinomas has been demonstrated [11][12][13]. The most c o m m o n form of this extension is pleura1 fluid (urine) associated with perirenal urinoma.…”
