尿管鏡下に切除した尿管ポリープの2例

Abstract

症例1(70歳女性).左水腎症の精査目的に著者らの施設へ紹介となった.症例2(59例女性).無症候性肉眼的血尿を主訴とした.いずれも自然尿細胞診はclass IIで, 排泄性尿路造影にて左尿管ポリープと診断し, 尿管鏡下に腫瘍切除術を行った.病理組織学的に線維上皮性ポリープで, 術後7～9ヵ月経過した現在, 再発はなく経過良好である

Two cases of ureteral polyp resected by a transurethral approach are presented. Case 1: A 70-year-old woman was referred to our clinic because of hydronephrosis incidentally found. Excretory urography demonstrated a filling defect with a long and round smooth contour in the left lower ureter without hydroureter. Urine cytology was negative for malignant cells. Under the clinical diagnosis of left ureteral polyp, polyp was resected transurethrally. The pathological diagnosis was fibroepithelial polyp. Case 2: A 59-year-old woman was referred to our clinic with a chief complaint of macroscopic hematuria. Excretory urography revealed a filling defect with a long and round smooth contour in the left upper ureter. Because urine cytology was negative for malignant cells, left ureteral polyp was suspected. After the operation by tranthurethral approach, the pathological diagnosis was fibroepithelial polyp. No intraoperative complication was observed in either case. Ureteral polyps resected by a transurethral approach are relatively rare. We reviewed and discussed 46 cases of ureteral polyp resected transurethrally, reported in Japan including our two cases.
