This invention, offers the internal organs form measurement methods and that measuring device, the urination obstacle measure system, and can be applied to these the ultrasonic probe which precision can measure the form of the internal organs such as bladder threely-dimensional well from the opening where it is limited. This invention making use of the ultrasonic probe where the plural sensors by the ultrasonic oscillator are arranged, from each sensor the ultra wave, when the opening of internal, for example it is bladder form measurement, transmits in the gap between the peritoneum and the pubis, crosses threely-dimensional and expands, receiving the ultra wave which is reflected in the front wall and the rear wall of the internal organs which are measured with each sensor, in order to measure the three-dimensional form of the internal organs, forms. In the urination obstacle measure system, measuring the urine quantity from three-dimensional form of the bladder which was measured in this way, it informs about the necessity of urination.本発明は、限られた隙間から膀胱等の臓器の形状を立体的に精度よく計測できる臓器形状計測方法とその計測装置、排尿障害対策システム、並びにこれらに適用できる超音波探触子を提供する。本発明は、超音波振動子による複数のセンサが配置された超音波探触子を用い、各センサから超音波を、体内の隙間、例えば膀胱形状計測の場合には腹膜と恥骨間の間隙に透過し、立体交差して広げ、計測される臓器の前壁及び後壁で反射した超音波を各センサで受信して、臓器の立体形状を計測するようになす。排尿障害対策システムでは、このようにして測定された膀胱の立体形状から蓄尿量を計測して排尿の必要を知らせる。
