Abstract:
Pelvic organs are generally sufficiently outlined by extraperitoneal fat, and there is a relative absence of physiologic motion. Computed tomography(CF) of the pelvic cavity is advantageous to demarcate anatomical features. It is important to standardize localization and volumetric measurement of intrapelvic organs in each plane of pelvic computed topography image. Forty four cases without pelvic pathology were studied in other to determine the normal morphology of the prostate and seminal vesicles on CT with the standard plane of greater trochanter to be appeared. The shape of pelvic cavity had android type in three-fifths and the size had 60.0~ 153.6mm(mean 95.3+/-17.7 mm) in anteroposterior diameter and 87.6~158.3 mm (mean 102.5+/-13.5 mm) in transverse. About four-fifths of the shape of the prostate had round type on the level of appearing to the largest prostate. About four-fifths of number of appearing plane of prostate on pelvic CT had 3 planes. The mean volume of the prostate was 32.6+/-7.2 ml and the volume of the prostate was well correlated with age(p<0.000). The mean anterior and lateral space of Retzius were 12.0+/-11.8 mm, 16.1+/-14.1 mm respectively. According to patient`s body weight and height, space were not correlated to body weight & height. About a half and one-third of the shape of the seminal vesicles had bow-tie and crescent type on the level of appearing to the largest seminal vesicles. About three-Fifths and one-fifth of number of appearing plane of seminal vesicles on pelvic CT had 2 and 3 planes. The mean length of right and left seminal vesicles was 40.4+/-5.2 mm and 38.7+/-6.1 mm respectively.
