title: [A Case Report of Pyothorax Due to Pyonephrosis].
abstract: A 77-year-old woman was referred to our hospital with complaints of fever and left chest pain. Computed tomography showed left pyothorax and left pyonephrosis with left ureter calculus. After admission, drainage of the left thoracic cavity was performed and she was treated with antibiotics. On the third hospital day, debridement for pyothorax was performed because her condition had not improved. During surgery, we found perforation of the diaphragm, and abscess appeared from the perforated area. We suspected that perforation of the diaphragm from the left pyonephrosis caused left pyothorax, and performed left nephrectomy. After the operation, relapse of the pyothorax and surgical wound infection occurred, but her condition improved and she discharged on the 46 th hospital day. Relapse of the abscess has not occurred.
