对26例急性管型坏死患者的肾做超声图象研究,男19例,女7例,年龄在13～83岁(54.2±18.4 mean±SD)。 患者取俯卧位,用直径13mm,频率3.5MH_2的换能器在背部矢状扫查,获得肾的纵切面的最大范围。超声技师在这个断面测量肾最大前后径(H)、长径(L)和H/L比率,超声技师不知患者的实验资料。对照组采用无肾、心血管疾病26人的52个肾超声图作对比。患者入院的第一天获得生化资料,并规定从急性肾衰到痊愈每2～3天检验血清肌氨酸肝和血钾水平。
26 cases of acute tubular necrosis of the kidney in patients with ultrasound image study, 19 males and 7 females, aged 13 to 83 years (54.2 ± 18.4 mean ± SD). Patients take the prone position, with a diameter of 13mm, 3.5MH_2 frequency transducer in the back of the sagittal scan to obtain the maximum range of the longitudinal section of the kidney. Ultrasound technicians measured the maximum anterior-posterior diameter (H), long diameter (L), and H / L ratio of the kidney in this section. Ultrasound technicians did not know the experimental data of the patients. Control group with no kidney, cardiovascular disease, 26 of 52 renal ultrasound contrast. Patients were admitted to the first day of biochemical data, and provides for recovery from acute renal failure to check serum sarcosine liver and potassium levels every 2 to 3 days.
