title: [Long-term results of venous surgery for cavernous erectile dysfunction].
abstract: BACKGROUND
  It is well known that the effectiveness of venous surgery declines during the follow-up period. The onset of recurrence after surgery varies greatly among patients. There are only a few studies which have evaluated the effectiveness of venous surgery with objective tests.
  
  
  METHODS
  We treated 123 cases of cavernous erectile dysfunction with venous surgery, and evaluated the results objectively. We performed intracavernous injection tests using 20 micrograms of prostaglandin E1 every 3 months until the recurrence of cavernous erectile dysfunction.
  
  
  RESULTS
  Mean follow up period was 32 months (0.2-134.0 months). According to the Kaplan-Meier analysis, the effectiveness of surgery at 1 year, 3 years, 5 years, and 10 years was 85%, 61%, 30%, and 26%, respectively.
  
  
  CONCLUSIONS
  There was no statistically significant difference between the outcomes following deep dorsal vein surgery and crural ligation surgery. Operative complications were more frequent, however in deep dorsal vein surgery.
