| The purpose of this study was to evaluate the variation of peak velocities of deep cavernosal arteriesaccording to sampling location in duplex Doppler ultrasound of the penis. Duplex Doppler ultrasound was performedfollowing an injection of prostaglandin E1 into a corpus cavernosum in 32 patients with erectile dysfunction.Doppler spectrum was obtained at two points in eacg deep cavernosal artery, one at the most proximal pont and theother at the most distal visible point in the straight course of the artery in penile shaft. The average peakvelocities at proximal portion was 40.15m/sec on right side, 37.88m/sec on left side, and 39.02cm/sec on bothsides. Those at distal portion were 21.41cm/sec on right, 17.88cm/sec on left, and 19.64% on both sides. The %ratio of peak velocity at distal portion devided by that at proximal portion was 55.2% on right, 48.0% on left,51.6% on both sides. The authors conclude that the peak velocities of deep cavernosal arteries are variableaccording to its Doppler sampling location and that the sampling location should be standardized and clarifiedwhen on perform duplex Doppler ultrasound of deep cavernosal arteries. |
