Evaluation of vascular changes in cavernous arteries by penile doppler ultrasound in patients undergoing laparoscopic radical prostatectomy.

Erectile Dysfunction

A prospective database of 83 patients undergoing LRP was analysed. PDUS were performed at baseline and twelve months after surgery. International Index of Erectile Function (IIEF) and Erectile Hardness Score (EHS) questionnaires were also evaluated. A 12-month decrease in all hemodynamic parameters of both cavernous arteries was found except for the end diastolic velocity (EDV) on the left cavernous artery.
