The role of colour Doppler imaging in the management of Peyronie's disease.
OBJECTIVE
To determine the role of colour Doppler imaging (CDI) in the investigation of erectile dysfunction in patients with Peyronie's disease.


METHODS
Fifty consecutive patients (age 35-75 years) with Peyronie's disease who were considered suitable for surgical treatment were investigated using CDI to determine the haemodynamic variables of penile vasculature after an intracorporeal injection of 20 microg of alprostadil (with manual self-stimulation). A clinician independently recorded the quality of erection and the deformity.


RESULTS
Twenty of 50 patients (40%) considered they had normal erectile function despite their penile deformity and all had normal responses, although they tended to exaggerate the degree of penile deformity. Of the 30 remaining patients, 21 who considered themselves to have erectile dysfunction had normal clinical and CDI haemodynamic responses to alprostadil. The remaining nine patients had a variety of erectile problems and whilst CDI showed altered haemodynamic values, in no case did CDI alter the proposed treatment based on the clinically apparent features of those patients.


CONCLUSIONS
Colour Doppler imaging of the penis after pharmacologically induced erection gives anatomical and functional information in patients with Peyronie's disease but does not provide useful additional information to aid the selection of surgical treatment for the disease.
