The present study assessed the canine prostate gland using B-mode real-time ultrasonography and correlated these findings with corresponding histologic sections. The prostate glands of 10 dogs were suspended in a saline bath and were scanned with an ultrasound probe. The glands were fixed and histologic sections were made. The sonograms were visually compared with the histologic sections. Areas having high collagenous tissue content appeared hyperechoic on the ultrasound scans. This hyperechogenicity was seen in the diffusely hyperechoic immature gland, the hyperechoic periurethral stroma, and the hyperechoic butterfly-shaped area seen on transverse scans. The butterfly-shaped area was isoechoic, with an elongated oval area seen on transverse scans. Areas of glandular epithelial content appeared hypoechoic on ultrasound scans. No zones comparable to the human prostate were observed.
