Contrast-Enhanced Ultrasound Evaluation of Canine Prostatic Hyperplasia Before and After Osaterone Acetate Therapy: Preliminary Results

This study investigates the effects of osaterone acetate (OSA) treatment on benign prostatic hyperplasia (BPH) in 15 dogs using contrast-enhanced ultrasonography (CEUS). The study measures canine prostate-specific esterase (CPSE) levels and prostate volume before and after treatment. Results show significant reductions in CPSE and prostate volume after 21 days of OSA treatment, with increased wash-in and wash-out times of the contrast agent, indicating reduced prostatic perfusion. These preliminary findings suggest that CEUS is a promising tool for monitoring BPH in dogs.
