Summary

This summary is machine-generated.

Canine prostate involution after castration continues long-term. Ultrasound shows reduced perfusion and minimal volume decrease over six years in neutered dogs, indicating ongoing prostatic changes.

Area Of Science

  • Veterinary Medicine
  • Diagnostic Imaging
  • Canine Urology

Background

  • Ultrasound imaging is standard for canine prostate assessment.
  • The role of castration in prostatic neoplasia is known, but long-term changes in neutered dogs are understudied.
  • No data exist on prostatic changes beyond 90 days post-castration.

Purpose Of The Study

  • To document long-term ultrasonographic changes in the canine prostate after castration.
  • To evaluate B-mode and contrast-enhanced ultrasound (CEUS) features of the prostate in neutered dogs over time.

Main Methods

  • Ten neutered dogs underwent B-mode and CEUS of the prostate at two time points, six years apart (T0 and T1).
  • Prostate volume was calculated using Atalan's formula.
  • CEUS assessed prostatic perfusion using SonoVue, measuring peak enhancement (PPI) and time to peak (TTP).

Main Results

  • Prostate morphology and echotexture remained similar on B-mode US, with a minimal volume decrease over six years.
  • Prostate perfusion significantly decreased between T0 and T1.
  • Mean PPI decreased from 54.9% to 29.6%, and mean TTP increased from 26.3s to 47s.

Conclusions

  • These findings provide baseline B-mode and CEUS data for the canine prostate in neutered dogs.
  • Prostatic involution following castration is a prolonged process, continuing for several months to years.
