| Popis: | 1)尿管腫瘍が泌尿器科外来および入院患者に占める割合は, それぞれ0.22%, 1.65%であった.2)年齢は45歳から83歳にわたっており, 平均年齢は59.14歳であった.3)性別では男:女の比率は2.5:1であった.4)患側は左側に多く, 発生部位は下部尿管1/3に多かった.5)臨床症状としては側腹部痛がもっとも多く, 肉眼的血尿がこれについだ.6) IVPでは5/7に水腎症または無機能腎を, 2/7では腫瘍部分の陰影欠損のみで水腎症は認めなかった.7)逆行性腎盂尿管造影では, 全例に腫瘍部尿管の閉塞ないし狭窄像を認めた.8) CTは全例に施行したが, 腫瘍が描出されたのは1例のみ(14.3%)であった.9)尿細胞診の陽性率は3/7 (42.8%)であり, 腫瘍のgradeと細胞診の結果は平行しなかった.10) 7例中6例に腎尿管全摘除術兼膀胱部分切除術を施行した.11)病理組織学的には, gradeとstageは相関した.high grade, high stageであるほど予後が悪かった Seven cases of primary ureteral tumors treated at Nagaoka Koseiren Chuo General Hospital in 1983 were reviewed retrospectively. The incidence of primary ureteral tumors among the out-patients in the urologic clinic of the hospital was 0.22% and the incidence among the in-patients was 1.65%. The patient's age ranged from 45 to 83 years (average: 59.14 years old). The ratio of male to female was 2.5: 1.0. The left ureter and the lower third of the ureter were involved more frequently than the others. The most common symptom was colicky flank pain (57% of the cases), which was followed by macroscopic hematuria. On IVP, 5 of the 7 cases showed a non-functioning kidney or hydronephrosis, but the others showed filling defects in the ureteral lumen without hydronephrosis. Diagnostic accuracy of CT was 14.3%. Diagnostic accuracy of urine cytology was 42.9% and the false negative rate was the same. Six of the 7 cases underwent total nephroureterectomy with bladder cuff excision. The higher the grade and stage of the tumor, the poorer the prognosis tended to be. |
