Two-dimesionanl ultrasound in combination with colour-coded and pulsed Doppler sonography was used to study the blood flow of the testes and prostate gland in 12 male dogs. After detection of the vessels by colour-coded Doppler sonography, the blood flow patterns were determined by pulsed Doppler sonography measuring and describing the systolic and diastolic peak velocity (SPV, DPV), the end-diastolic velocity (EDV), the time-averaged maximum velocity (TAMAX), the pulsatility (PI) and resistance index (RI), as well as the ratios of the systolic peak velocity and en-diastolic velocity (A/B) and the systolic and diastolic peak velocities (S/D). The blood flow of the testicular artery was measured in within the pampiniform plexus. The prostatic blood supply was measured in the prostatic artery. The physiological testicular flow pattern was monophasic with a high diastolic flow. Under physiological conditions the prostatic blood flow pattern was biphasic. The present results give basal information on the perfusion in healthy reproductive organs of the male dog and demonstrated that the colour-coded and pulsed Doppler sonography give additional valuable information which improves the andrological giagnostics in the dog.

Abstract
Two-dimesionanl ultrasound in combination with colour-coded and pulsed Doppler sonography was used to study the blood flow of the testes and prostate gland in 12 male dogs. After detection of the vessels by colour-coded Doppler sonography, the blood flow patterns were determined by pulsed Doppler sonography measuring and describing the systolic and diastolic peak velocity (SPV, DPV), the end-diastolic velocity (EDV), the time-averaged maximum velocity (TAMAX), the pulsatility (PI) and resistance index (RI), as well as the ratios of the systolic peak velocity and en-diastolic velocity (A/B) and the systolic and diastolic peak velocities (S/D). The blood flow of the testicular artery was measured in within the pampiniform plexus. The prostatic blood supply was measured in the prostatic artery. The physiological testicular flow pattern was monophasic with a high diastolic flow. Under physiological conditions the prostatic blood flow pattern was biphasic. The present results give basal information on the perfusion in healthy reproductive organs of the male dog and demonstrated that the colour-coded and pulsed Doppler sonography give additional valuable information which improves the andrological giagnostics in the dog.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
