[Comparative study of prostatic dimensions by plain radiography, urethrocystogra-phyand necropsy]

ABSTRACT

The Prostate gland is the major accessory gland in male dogs. Prostate disease is a common problem in older intact male dogs. The aim of this study was to determine prostatic dimensions by plain radiography and urethrocystography in dogs and compare them with actual sizes. Plain radiography and urethrocystography were performed on 10 intact young adult male dogs. After necropsy length, width, height, volume and weight of prostate glands were measured. All statistical analyses paired t test, linear regression and correlation coefficient were performed. Prostate glands of 9 dogs could be evaluated with urethrocystography and reliable length and height of prostate gland were measured. Means of prostatic length and height were smaller than their actual sizes but still had significant correlation [p<1=0.05]. Equations between prostatic and actual lengths and depths in urethrocystography were L=0.91 x l + 0.57 [R[2] = 0.84] and Z= 1.36 x z - 0.79 [R[2] = 0.76] respectively. The results of this investigation were showed that urethrocystography could be used for prostatic measurement. This method can be as a reliable technique, whenever ultrasonography can not be performed
