Seventeen cases of peritonitis due to rupture of a pyonephrosis have been reported. The majority of these cases occur secondary to renal stones. Only two cases of ruptured pyonephrosis with concurrent kidney neoplasm have been described and only one of these presented as an acute peritonitis. In this presentation we discuss an unusual case of a 68 year old man with a chronic history of bilateral nephrolithiasis and recent pyonephrosis. He presented acutely with peritonitis and was later found to have a carcinosarcoma of the kidney. The case highlights the importance of recognizing the possibility of underling renal carcinoma in patients presenting with a ruptured pyonephrosis and discuss steps to avoid this serious complication.

已有 17 例因脓肾破裂导致腹膜炎的病例报告。这些病例多数继发于肾结石。仅描述了两例并发肾肿瘤的脓肾破裂病例，其中只有一例表现为急性腹膜炎。在本次报告中，我们讨论了一例不常见的病例，患者为 68 岁男性，有双侧肾结石的慢性病史和近期脓肾病史。他表现为急性腹膜炎，随后发现患有肾癌肉瘤。该病例强调了在出现脓肾破裂的患者中认识到潜在肾癌的可能性的重要性，并讨论了避免这种严重并发症的措施。
