Purpose:
A prospective, randomized, double-blind study was done to determine whether alkalization of prostaglandin E1 decreases pain associated with intracavernous injection.
Materials And Methods:
Ten subjects with a history of pain following at least 70% of injections of prostaglandin E1 received 2 injections of prostaglandin E1, 1 with and 1 without sodium bicarbonate. Patients reported the duration and intensity of pain following each injection.
Results:
Comparing injections of prostaglandin E1 with and without bicarbonate, there were no significant differences in number of subjects reporting pain, or duration and intensity of pain.
Conclusions:
Addition of sodium bicarbonate does not alleviate penile pain associated with injection of prostaglandin E1.
