title: [Analysis of Doppler ultrasonography in penile artery].
abstract: OBJECTIVE
  To study nomal valuels of PI, RI and S/D in healthy male penile dorsum artery (DA) and cavernosal artery (CA).
  
  
  METHODS
  257 healthy mature men were divided into 5 groups by age. Group 1: <30, n=65; Group 2: 30-39, n=83; Group 3: 40-49, n=61; Group 4: 50-59, n=38; Group 5: > or = 60, n=10. Hibateral PI, RI and S/D values of penile dorsum artery and cavernosal artery were examined by Logidop(r)2 Type Digital Doppler Ultrasonography.
  
  
  RESULTS
  There were no significant difference for PI, RI and S/D of penile dorsum artery and cavernosal artery not only in personal left and right artery but also in different age groups. Normal values advised: (1)LDA:PI 1.43-3.43, RI 0.72-0.92, S/D 2.68-10.56. (2)RDA PI 1.47-3.47, RI 0.73-0.93, S/D 3.27-10.09. (3)LCA:PI 1.49-3.21, RI 0.74-0.90, S/D 3.17-9.55. (4)RCA:PI 1.93-3.27, RI 0.72-0.90, S/D 3.22-9.42.
  
  
  CONCLUSIONS
  Doppler ultrasonography is a favorable method in filtering penile arterial function.
