A retrospective analysis of radiographs from 24 healthy young adult male Beagles is presented. The ventrodorsal and craniocaudal prostate gland dimensions were measured, and expressed as a ratio of the distance between the cranial aspect of the pubic bone and the sacral promontory. The largest acceptable prostatic dimension, as visualized on the lateral radiographic view was 70% of the pubic-promontory distance. In 30 cases of canine prostatic disease, prostatomegaly was not specific for the cause of prostatic disease, except if the apparent parenchymal dimensions were 90% of the pubic-promontory distance where neoplasia, abscess, and paraprostatic cysts were the principle considerations. Narrowing of the prostatic portion of the urethra was observed only in association with abscess, neoplasm, or noninflammatory nonneoplastic disease (possibly benign hypertrophy/hyperplasia), whereas widening of this part of the urethra was not observed. Asymmetric distribution of the prostatic parenchyma around the urethra was not specific for type of disease, but was indicative of focal or regional (rather than diffuse) parenchymal disease. Destruction or distortion of the prostatic urethra was observed only as a result of neoplasia, but appearance was insufficient to differentiate prostatic from nonprostatic cell types.
