異所開口で逆流を伴う完全重複腎盂尿管に発生した腎盂扁平上皮癌の1例

Abstract

Squamous cell carcinoma of the renal pelvis is a relatively rare disease. Recently, we observed a case of squamous cell carcinoma of the renal pelvis with vesicoureteral reflux in a 49-year-old female patient. Her main symptom was abdominal pain on the left side. The complete duplications of uretero-pelvis on both sides, and vesicoureteral reflux in the upper left part of the kidney were recognized by means of various examinations. During the operation, a tumor was found in the upper left renal pelvis, and in the ureter belonging to the upper left renal pelvis. Pathologically, it was diagnosed as a squamous cell carcinoma. After the extraction of the left uretero-pelvis, 50 Gy of radiotherapy was administered to the patient. However, she died four months after the operation.
