腎嚢胞に対する経皮的povidone iodine注入療法 - 臨床成績の検討 -

Abstract

23例の腎嚢胞患者に対して, 超音波ガイド下に穿刺後, 10%povidone iodineを注入した.自覚症状のあった14症例中12例で術後に症状が消失した.また, 顕微鏡的血尿を認めた1例では術後に血尿が消失した.術後平均観察期間143日で, 超音波検査あるいはCT scanにて, 腎嚢胞の消失あるいは著明な縮小を認めた(平均縮小率86.6%).合併症としては, povidone iodineの腎周囲への漏出という手技的な原因と考えられるperinephritisによる発熱を1例に認めたが, 他の症例では特に合併症を認めず, またpovidone iodineによると思われる副作用も認めなかった

Percutaneous puncture followed by instillation with 10% povidone iodine was performed on 23 patients with benign renal cysts. All patients showed remarkable reduction (mean: 86.6%) in size of renal cyst on sonography or computed tomography within a short time (mean: 143 days). Twelve (85.7%) of the 14 symptomatic patients due to the disease were relieved of subjective symptoms such as lumbago after instillation. In a 71 year-old man, microscopic hematuria disappeared after this treatment. There were no complications with this treatment except in one patient who suffered from perinephritis due to a technical problem. This treatment seems to be a safe and effective way to prevent recurrence of cystic fluid.
