Comparative Study
[Intracavernous injection of lipo prostaglandin E1 for the diagnosis of impotence: a comparative study with prostaglandin E1-CD].
Intracavernous injection of 20 micrograms prostaglandin E1-CD (PGE1-CD, 8 cases), 5 micrograms lipo prostaglandin E1 (Lipo PG-E1, 8 cases) or 10 micrograms Lipo PGE1 (9 cases) was performed in patients with functional impotence in order to comparatively analyze the diagnostic efficacy of these drugs. Full erection was observed in all patients who received intracavernous injection of 20 micrograms PGE1-CD or 10 micrograms Lipo PGE1. However, full erection was observed in 4 out of 8 patients administered 5 micrograms Lipo PGE1. ⋯ With regard to these RigiScan data and duration of erection, there were no significant differences among the 3 groups. There were no severe side effects in any of the patients. These findings indicate that 10 micrograms Lipo PGE1 and 20 micrograms PGE1-CD have similar effects and that Lipo PGE1 may be an effective drug for the diagnosis and treatment of impotence.
