A CASE OF INVERTED PAPILLOMA OF THE URETER

　85歳の男性にみられた左尿管のinverted papillomaの1例について報告した。主訴は肉眼的血尿で，順行性腎盂撮影などにて左尿管腫瘍と診断し，尿管下端切除＋尿管膀胱新吻合術を施行した。病理組織学的にinverted papillomaと診断された。自験例は文献上本邦第3例目の尿管発生inverted papillomaと思われる。

A 85-year old male was admitted to the hospital because of macroscopic hematuria. Excretory urogram and left antegrade pyelogram showed left hydronephrosis with a sharp-edged defect at the lower end of left ureter. Considering his age and renal function, ureteroneocystostomy with partial uretere-ctomy was performed. Pathological examination revealed inverted papilloma of the left ureter. This seems the third case of inverted papilloma of the ureter reported in Japan.
