摘要
选本地健康成年犬20只(体重为10.5～25.0kg),在全麻状态下取腹背位评定,主要采用腹部压迫法摄取造影片。结果:(1)kVP=体厚(cm)+55,mAs=50(中速钨酸钙增感屏);(2)以跖外静脉及隐静脉为注射部位,60％复方泛影葡胺(0.50～0.75mL/kg在1min左右注完);(3)摄取肾实质、肾盂及全尿路的最佳时机分别为1、15及30min左右;(4)肾脏位于脊柱两侧T_(13)～L_4水平处。肾长径约为横径的2倍,约为L_2长度的3倍。肾盂属于肾内型,多呈漏斗状或三角形。肾盂的髓质边缘处有6～8对锯齿状肾盂盲囊。个别犬的输尿管有迂曲现象。
The intravenous urography was made on twenty generalanaesthetized adult dogs. Ventrodorsal view radiographys were taken withcompression method principally. The results are as follows: Exposurefactors: KVP=body thickness (cm) + 55 and mAs=50 (midspeedintensifying screens with calcium tungstate). The contrast medium (60 %Co. meglumine diatrizoate) at dosage of 0.50～0. 75 mL/kg was injectedinto external metatarsal or saphenous veins within one minute or so. Theoptimum time for radiographing the renal parenchymas, renal pelves andwhole urinary tract are about 1, 15 and 30 minutes, respectively. Theleft kidney is commonly at the level of L_(2-4) while the right one is at thelevel of L_(1-5). The length of left kidney is 8.06±0.91 cm and that ofright kidney is 7.78±0.94 cm. The width of left kidney is 4.91±0.74 cmcomparing with the right one 4.58±0.57 cm. The kidneys are roughlythree times of the length of the second lumbar vertebrae (L_2). Both theureters are about 20～25 cm in length and 0.2～0.4 cm in width.
