The lateral roentgenograms of the bladder, urethra, uterus and vagina in 34 normal women, 20 to 55 years of age, were taken under the same condition. In order to make geometrical measurements of the roentgenograms taken under strictly the same position, I believe that it is most rational to consider the anatomical conjugation (conjugata anatomica) as the baseline. l. The bladder roentgenogram shows that the rate of enlargement of the anterior, or abdominal, wall of the bladder, is larger than that of the posterior, or trterovesical, wall depending on the position and condition. 2. The position of the external (urethral) meatus can be located by the lateral roentgenogram as follows: take a point on the line extending the anatomical conjugation 4.6±3.6mm inferiorly from the superior border of the symphysis pubis, and from there drop a vertical line 69.7±2.1mm posteriorly toward the sacrum. The end of the vertical line shows the external meatus. 3. The position of the internal meatus can be located by the lateral roentgenogram as follows: take a point on the anatomical conjugation 26.7±2.1mm from the superior border of symphysis toward sacral promontory and drop a vertical line 40.1±1.8rnm posteriorly toward the sacrum. The end of the vertical line indecates the internal meatus. The measurements reported above are considered average for the Japanese women. 4. The position of the external meatus approaches the vaginal orifice with age, and the internal urethra has a tendency to occupy a mare inferior position toward the outer genitalia. 5. The external and the internal meatuses vary their position with change of body position and with pressure. The range of mobility of the internal meatus in a vertical direction toward the anatomical conjugation, i.e. in a sagittal direction to the body, is greater than that of the external meatus. The range of mobility of the external meatus in a horizontal direction to the anatomical conjugation i.e. in an upper and lower direction to the body, is greater than that of the internal meatus.
