title: [Dynamic infusion cavernosometry and cavernosography for the diagnosis and classification of venous erectile dysfunction].
abstract: OBJECTIVE
  To explore the procedures of dynamic infusion cavernosometry and cavernosography (DICC) and their application in the diagnosis and classification of venous erectile dysfunction (VED).
  
  
  METHODS
  This study included 103 ED patients, aged 20 to 43 years, highly suspected of VED, with disease courses of 4 months to 6 years. DICC was performed and analyses were made on the results, especially the parameters of flow-to-maintain (FTM) and pressure decay (PD) in the corpus cavernosum.
  
  
  RESULTS
  Based on the parameters of FTM and PD, 21 of the patients were normal, 5 were suspected of VED, 39 had mild VED, 25 had moderate VED, and 13 had severe VED. Penile subcutaneous hematoma was found in 4 of the patients, all recovered after 3 to 5 days, with no other complications.
  
  
  CONCLUSIONS
  DICC is a reliable, safe and minimally invasive method for the diagnosis and classification of VED.
