The present study was conducted to measure the various indices of Testicular and Prostatic Artery in Dogs at Different Age using Colour-coded and pulsed Doppler Sonography.
Colour-coded and pulsed Doppler sonography was used to study the blood flow of the testes and prostate gland in a total of 6 mongrel male dogs at different age starting from 4 weeks of age. After detection of the vessels by colour-coded Doppler sonography, the blood flow patterns were determined by pulsed Doppler sonography and measured the Peak systolic Velocity (Vmax), the end-diastolic velocity (Ved), the pulsatile index (PI) and resistance index (RI) in relation to their age.
Results: The physiological testicular flow pattern was monophasic with a high diastolic flow While the prostatic blood flow pattern was biphasic. Vmax, Ved, PI and RI of testicular artery show variation with age of mongrel dogs.
The results of the present investigation demonstrate that the colour-coded and pulsed Doppler sonography give additional valuable information which improves the andrological diagnostics in the dog.
