|
The purpose of this study was to determine and compare prostate size using ultrasound and computedtomography (CT). The prostate gland was evaluated in eight normal Beagle dogs. Length, depth, and width of theprostate gland were measured by ultrasound and volume of the prostate was obtained from the two ellipsoid formula(US1, US2). Height, length, width, area, and volume of the prostate gland were measured by CT. Ratios of prostaticheight, length, and width to the sixth lumbar vertebral body length were calculated. There was no significant differencebetween the US1 and US2 method, and between US2 and CT method, respectively. The prostatic volume calculatedby US1 method was significantly lower than those with CT (p = 0.029). The Upper limits of ratios of prostate length,height, and width to the length of the sixth lumbar vertebra were 1.3, 1.1, and 1.7, respectively. Among these prostatedimensions, prostate length and height could be a useful index in estimating prostate size regardless of body weight.
