This treatment is effective in providing adequate erections

• patients are told to void to make sure the urethra is moist
• the pellet is inserted into the urethra via a small applicator and the penis massaged
• in clinical practice only the higher dosages of 500 µg and 1000 µg are effective
• erection occurs in under 10 minutes following insertion of transurethral alprostadil and lasts for 20-60 minutes
• the incidence of priapism is lower than with intracavernosal alprostadil (1)
• the long-term side effects and efficacy of transurethral alprostadil are uncertain
• transurethral alprostadil is less invasive and less effective and works more slowly than injection therapy

  • penile pain (30-40%) and dizziness (2-10%)
