Determination of canine prostatic volume using transabdominal ultrasonography

Area of Science:

• Veterinary Medicine
• Diagnostic Imaging
• Canine Anatomy

Background:

• Accurate measurement of canine prostate volume is crucial for diagnosing and monitoring prostatic diseases.
• Traditional methods like water displacement can be time-consuming and destructive.
• Ultrasonography offers a non-invasive alternative for volumetric assessment.

Purpose of the Study:

• To compare prostatic volume measurements obtained via ultrasonography with those from water displacement.
• To determine the specific gravity of the canine prostate gland.
• To develop a predictive formula for canine prostatic volume based on ultrasound-derived dimensions.

Main Methods:

• Prostatic glands from 12 intact adult male dogs were utilized.
• Transabdominal ultrasonography (4-7 MHz transducer) was performed to obtain prostate dimensions (L, W, D).
• Prostatic volume was calculated using ellipsoid and box formulas, and measured via water displacement post-excision.

Main Results:

• The mean specific gravity of the canine prostate was 1 ± 0.05 g/cm³.
• A strong positive correlation (R² = 0.94) was found between ultrasound-derived and water displacement volumes.
• A predictive formula was established: VM = [1/2.6 (L x W x D)] + 1.8 (cm³).

Conclusions:

• Ultrasonography provides a reliable and accurate method for determining canine prostate volume.
• The developed formula enables accurate prediction of prostatic volume using simple ultrasound measurements.
• This non-invasive technique aids in the clinical assessment and management of canine prostatic conditions.
