| Abstract | 「要旨」 99mTc-DTPA連続腎シンチグラフィーを施行した700症例中, シンチグラム上, 光子欠損腎を呈した12症例について, その成立機序と臨床的意義について検討した. 内訳は水腎症7例, 一側性多発性腎嚢胞症1例, 嚢胞腎4例といずれも良性疾患に起因するものであった. 大きさについては12例中10例(83%)に腫大を認め, 残り2例は正常範囲であった. 同期間中の腎悪性腫瘍症例15例中12例(80%)に腫大を認めるも, 光子欠損腎は認めなかった. したがって光子欠損腎となるには血流が無いかきわめて乏しい病変で, 光子を十分に吸収するに足りるだけ腫大していることが必要であることが分った. 腎孟造影法や99mTc-DMSA静態腎シンチグラフィーで患側腎が描出されない症例において99mTc-DTPA連続腎シンチグラフィーで光子欠損腎を呈した場合には良性病変による可能性が最も考えられる. |

| Abstract | [Summary] Serial renal scintigraphy with 99mTc-DTPA is widely used to assess perfusion, filtration and excretion. During a first few minutes, the tracer is distributed to the organs n proportion to the amount of blood flow. Of 700 patients with 99mTc-DTPA series, we noticed 12 cases of a photon-deficient kidney, corresponding to the entire missing kidney on an IVP. Etiology and mechanism of photon-deficient kindneys were discussed in comparison with 15 cases of renal malignancy in the same duration. Etiologies include 7 hydronephrosis, 1 unilateral multicystic kidney, 4 polycystic kidneys. In 10 cases, photon-deficient kidneys were significantly enlarged. The rest two cases revealed normal sized kidneys. In 12 of 15 renal malignant cases, the diseased kidneys were significantly enlarged. The rest three cases showed no enlargement. However no photon-deficient kidneys were noted in renal malignant Cases. In conclusions, 1)Etiologies of photon-deficient kidneys are most likely to be benign disorders, 2)Their mechanism could be due to nonfunctioning avascular enlargement of kidney, sufficient to absorb gamma ray. 3)No significant information was obtained with 99mTc-DMSA static scintigraphy in photon-deficient kidneys. |
