慢性腎不全患者の腎結石に合併した腎盂扁平上皮癌の1例 : 本邦170例の臨床的検討

Abstract

血液透析中の腎結石患者に発生した腎盂扁平上皮癌の1例(59歳男)を報告し, 本邦170例について臨床的考察を行った

A case of squamous cell carcinoma of the left renal pelvis associated with chronic renal failure on hemodialysis is reported. The patient, a 59-year-old man, had undergone bilateral nephrolithotomy, in 1966, followed by right ureterolithotomy and bilateral percutaneous nephrolithotripsy, but residual stones existed. He suffered from left flak pain and fever, and computed tomography (CT) and magnetic resonance imaging (MRI) revealed left perirenal abscess in July 1994. Percutaneous drainage and antibacterial chemotherapy were performed, but his symptoms did not improve. Three months later, CT and MRI revealed a mass in the left perirenal space and destruction of the 12th thoracic vertebra, which were considered to be infectious changes. On November 9, 1994, left nephrectomy was performed. Histopathological diagnosis was moderately differentiated squamous cell carcinoma, grade 2, INF-gamma, pT4, pR1, pL0 and pV1. In spite of irradiation therapy, he died on January 19, 1995.
