Relationship between vesico-ureteral reflux and trigonal configuration was studied by using three dimensional mapping device that was developed and patented by me. (Japan. Pat. 4-95002, USA Pat. 5228429 EPC pat 92100009.7) Methods :Three dimensional mapping device and software was developed for this purpose. This device consists of multi-linked plural arms and angle sensors. Software was developed by using programming language "C" to calculate the three-dimensional co-ordinate of the trigon.Angle data from the sensors were transferred to the computer and trigonal configuration was displayd by the software.Results :The ureteral orifices were not fixed but moving extensively with filling of the bladder. Therefore, trigonum were stretched and transformed with filling of the bladder. We compared the stretching rates between VUR and non-VUR cases. The result shows that treigonum stretched only longitudinally in non-VUR case however in VUR case stretched equally between longitudianl and lateral direction. This fact suggests that muscular development between bilateral ureteral orifices plays an important role to prevent VUR.So stretching direction deferent between VUR and non-VUR groups appears to have a remarkable importance in VUR diagnosis.

应用自行研制并申请专利的三维标测装置，研究膀胱输尿管反流与三角构型的关系。(日本。帕特。邮编：4-95002，美国帕特5228429 EPC PAT 92100009.7)方法：为此研制了三维标测装置及软件。该装置由多联多臂和角度传感器组成。结果：输尿管开口不是固定的，而是随着膀胱的充盈而广泛移动。因此，三角区随着膀胱的充盈而伸展和变形。我们比较了VUR和非VUR患者的伸展率。结果表明，在非输尿管返流病例中，海绵体仅在纵向上伸展，而在输尿管返流病例中，其伸展方向在纵横两个方向上是相等的。提示双侧输尿管开口之间的肌肉发育在预防VUR中起着重要作用，因此VUR组与非VUR组伸展方向的差异对VUR的诊断具有重要意义。
