[Value of degree diagnosis with color Doppler flow imaging in the treatment of male erectile dysfunction].
OBJECTIVE
To study the value of degree diagnosis with color Doppler flow imaging (CDFI) in the treatment of male erectile dysfunction (ED).


METHODS
After CDFI and intracavernosal vasoactive agent injection (ICI) with papaverine 60 mg and prostaglandin E(1) 10 microg, 198 male ED patients were divided into 4 groups by their penile stiffness based on the Schramek criterion. The therapeutic methods such as antibiotics for prostatitis, sexual behavior therapy, sildenafil, vacuum constriction device (VCD), vena fistula repairing operation, prosthetic implantation and enhanced external counterpulsation (EECP) were recommended to the patients according to their different penile stiffness degree and their different preferences.


RESULTS
Prior to ICI, there was no significant difference in the cavernosa artery peak systolic velocities (PSV), end diastolic velocities (EDV), resistant indexes (RI), dorsal artery PSV, EDV, RI and deep dorsal vein velocity (V) (P > 0.05). After ICI, the cavernosa artery PSV, EDV and RI were significantly different (P < 0.05) while other indices were not (P > 0.05). The patients were treated differently according to their preferences. The selective goal-oriented therapy increased the satisfactory rate to 91.91% (182/198).


CONCLUSIONS
Based on the penile stiffness degree with CDFI plus ICI, different therapeutic methods yield a better clinical outcome.
