馬蹄鉄腎に合併した腎孟移行上皮癌の1例

Abstract

A case of transitional cell carcinoma of the renal pelvis in a horseshoe kidney was reported. The patient was a 27-year-old man who came with the chief complaint of gross hematuria, and intravenous pyelography demonstrated a horseshoe kidney with nonfunctioning left kidney. On admission he received several urological examinations, and additionally translumbar pyelography for the left kidney was performed and at that time the urine sample was collected from the left renal pelvis. The cytological examination of the urine by Papanicolaou's stain revealed atypical transitional epithelial cells. We diagnosed as transitional cell carcinoma of the renal pelvis in a horseshoe kidney before the operation and performed left hemi-nephrectomy and total ureterectomy with partial cystectomy. Histologically, tumors in the left renal pelvis were papillary transitional cell carcinoma. After the operation the patient received 60Co irradiation and now he is in good general health without signs of recurrence or metastasis. In Japan 14 cases of renal tumor associated with a horseshoe kidney were reported until 1973 and our case was the 15th case.
