動脈硬化が原因と考えられた腎自然破裂の1例

Abstract

44歳男, 被膜下血腫を伴った腎自然破裂後患側腎の機能回復のみられなかった1例

A case of spontaneous renal rupture with subcapsular hematoma was reported. The patient was a 44-year old man complaining of a sudden left flank pain without any recent history of trauma. His abdominal ultrasonography (US), computerized tomography (CT) and renal angiography demonstrated left renal rupture with subcapsular renal hematoma. Cytological examination of left upper urinary tract revealed a suspicion of a neoplasma of renal pelvis and left renal function was not recovered. Therefore, left total nephro-uretectomy was performed, and histological examination revealed hemorrhage and infarct due to the severe arteriosclerosis and intestinal nephritis without malignancy. Sixty-three cases of non-traumatic subcapsular renal hematoma reported previously in the Japanese literature are reviewed with some statistical analyses.
