THE ROENTGEN DEMONSTRATION OF TIME PREVFSICAL SPACE (SUPPLEMENTORY REPORT)

Abstract

I have studied the various prevesical radiograms in normal persons and urological patients, injecting “Sugiuron” radiopaque dye) diluted twice as much by physiological saline into the prevesical space.
1) In the normal bladder, when the bladder is empty, the prevesical radiogram is emerged as a symmetrized crescent-shape with a downward convex surface around the symphisis ossium pubis, and when iilled, it comes into sight as a round ring figure.
2) In the tuberculous bladder, when the capacity of bladder is 200cc or more, the prevesical radiogram is alomost same with a normal bladder, but when it is lesa than 200cc, I recognized the radiograms as follows.
a) when capacity is 100-200cc, the upper brim is apt to be in disorder.
b) when capacity is 100cc or less, the upper brim is unsymmetrized convex and the contrast medium stays plentifully in the side of affected kindney.
3) In the bladder tumor, if the tumor grows up to a certain size, a lacune is noticed at the tumid part in empty bladder, and if the tumor is malignanti, the ring figure is crooked remarkably in full bladder.
4) In the prostatic hypertrophy the prevesical radiogram appears to be a symmetrized spindel figure and a lacune caused by the hypertrophied prostate is recognized in empty bladder.
