A group of 516 patients was studied using the routine renographic method. It can be admitted that 3 min after registration of maximum radioactivity in the kidney the curve of the radionephrogram in the interval of 7 min and that of radioactivity in the cardiac area within the same time interval are similar. Proceeding from this supposition coefficients of intensity of hippuran comparative outflow from the kidneys (K), from the kidney and blood (D) have been proposed. Using K and D coefficients the criteria of an extent of urinary passage delay from the upper urinary tract were determined. It has been established that renal function increases with age; therefore, age should be taken into consideration while assessing renographic results. In nephroptosis due to kidney forward shift the renal function index is to be understated. Renography has been shown advantageous in the evaluation of urine function and passage before chromocystoscopy in cancer patients.
采用常规肾图检查法对516例患者进行了研究。可以认为，在肾脏放射性活度达到最大值记录后3分钟，7分钟内放射性肾图曲线与同一时间间隔内心脏区域的放射性活度曲线相似。基于这一假设，提出了马尿酸从肾脏的相对流出强度系数（K）、从肾脏和血液的相对流出强度系数（D）。利用K和D系数确定了上尿路尿液通过延迟程度的标准。已经确定肾功能随年龄增长而增强；因此，在评估肾图检查结果时应考虑年龄因素。在因肾脏向前移位导致的肾下垂中，肾功能指标会被低估。肾图检查已被证明在评估癌症患者膀胱镜检查前的尿液功能和尿液通过情况方面具有优势。
