| Abstract | 「要旨」 男性不妊症の原因として精索静脈瘤が疑われた20症例に, 99mTc-HSA 20mCiを用いて陰嚢部のシンチグラフィを施行した. 片側性精索静脈瘤13症例については, シンチグラフィで全例に精索静脈瘤を認めたが, 超音波検査で精索静脈瘤を検出したのは12例であった. 両側性精索静脈瘤2症例については, 超音波検査では2例とも両側に精索静脈瘤を検出しえたのに対し, シンチグラフィでは両側に精索静脈瘤を検出したのは1例のみであった. また, RIアンギオグラフィによる精索静脈瘤の検出率は, 15例中2例 (13%) にすぎず, 静態イメージでは, 立位における検出率が, 15例中14例 (93%) と最も高く, 臥位および立位バルサルバのイメージでは, 9例 (60%) であった. 以上, シンチグラフィは, 超音波検査とともに精索静脈瘤の検出に有用な検査法と思われた. |

| Abstract | [Summary] The usefulness of scrotal scintigraphy was evaluated to detect the varicoceles in the infertile men. In 20 patients who were clinically suspected of having varicoceles, scrotal scintigraphy was performed using a small-field gamma camera and 20mCi of 99mTc-HSA. Radionuclide studies were done both in the dynamic and static images. In the dynamic study, serial sixteen 5-sec. images were obtained 15 sec. after injection. Static images were obtained 3 min. after injection (1) at the supine position without Valsalva maneuver, (2) at the erect position without Valsalva maneuver and (3) at the erect position with Valsalva maneuver. In 5 of 20 patients, varicoceles were diagnosed by physical examination alone. Fourteen patients with varicoceles were easily demonstrated by ultrasonography and 15 patients by scrotal scintigraphy. Dynamic images detected the varicoceles in 2 (13%) of 15 patients. Static images detected the varicoceles in 9 (60%) at the supine position, in 14 (93%) at the erect position without Valsalva maneuver, and in 9 (60%) of 15 patients at the erect position with Valsalva maneuver. In radionuclide studies, the static images at the erect position without Valsalva maneuver detected varicoceles with the highest sensitivity. Scrotal scintigraphy and ultrasonography were suggested to be useful for the detection of varicoceles in the infertile men. |
