项目摘要

On treating infants with presumed ureteropelvic junction obstruction (UPJO), obstructive state should be evaluated clinically but the precise method to describe the degree of obstruction of infantile UPJO has not been established. This study was carried out to evaluate urinary flow as well as the renal function on these conditions by using advanced image processing technology on data of diuretic renography and to reflect the result for their management. During the scheduled period from 2000 to 2001, new visualization technique was attempted for infantile UPJOs using purchased instruments and softwares (AVS) to evaluate their urinary flow. We also published the results of the previous clinical analysis. After diuretic renographic data were formated to be visualized by the AVS system, the urinary flow was visualized by animation, 3-dimensional image, which made one to understand the flow more visually. The urinary analysis was done by creating the subtraction images and they were suggested to be useful for analyzing the flow. Basic volume visualization research was also carried out by using volumerendering technique for multe-dimesional time space. This technique is a new technique which evaluate the direction of the urinary flow. These results can be applied to the large number of cases to realize the nature of the infantile hydronephrosis and to improve the management of the patients with the disease.

在治疗婴幼儿肾盂输尿管连接部梗阻(UPJO)时，应对梗阻状态进行临床评估，但目前尚无确切的方法来描述婴幼儿UPJO的梗阻程度。本研究应用先进的图像处理技术，对利尿性肾造影术后的尿流量及肾功能进行评价，并将结果反映出来，为临床处理提供依据。在2000年至2001年期间，使用购买的仪器和软件(AVS)对婴儿UPJO进行了新的可视化技术的尝试，以评估他们的尿流。我们还发表了之前的临床分析结果。通过AVS系统对利尿剂肾图数据进行可视化处理后，通过动画、三维图像对尿流进行可视化，使患者对尿流有更直观的了解。尿液分析是通过创建减影图像进行的，它们被认为是分析流动的有用工具。并利用多维时空的体绘制技术进行了基础体可视化研究。这项技术是一种评估尿流方向的新技术。这些结果可应用于大量病例，以了解婴幼儿肾积水的性质，提高对本病患者的治疗水平。
