title: [A case of renal cell carcinoma in a horseshoe kidney].
abstract: A-50-year-old patient visited our hospital to have further examination for left renal mass. Drip infusion pyelography revealed a cluster of calculi in the upper pole of the left kidney. Computed tomography and magnetic resonance imaging revealed a heterogeneous mass on the left side of a horseshoe kidney. Left nephrectomy was performed through an abdominal transperitoneal approach. An operation for dividing isthmus was simultaneously done using a microwave tissue coagulator. Histopathological findings showed grade 1 > 2, pT1aN0M0, clear cell subtype, renal cell carcinoma. Convalescence was uneventful and the patient was free of tumor at one year postoperatively.
