To evaluate the efficacy, safety and patients' preference of different treatment modalities of ED in men with SCI. Sixty SCI men with ED were included in the study. They were divided into three groups. Group A received sildenafil, group B received intracorporal injection (ICI) and were then shifted to sildenafil and group C used vacuum constriction devices (VCD) and were then shifted to sildenafil. Erection was evaluated before and after each treatment. Ninety percent of patients reported improvement of erection after sildenafil and ICI treatment according to IIEF-EF and only 70% of patients reported improvement in erection with VCD. However, 14 patients reported that they preferred sildenafil due to the easier route of administration. In men with SCI, sildenafil is the most effective treatment and is widely accepted. ICI, VCD therapy in SCI patients should be used according to patient's preference and choice.
The objective of this study is to evaluate the side effects of intracavernous vasoactive agents on clinical and sonographic basis. Two groups of patients were included, group I included 168 ED patients trained on self-injection therapy using one of the three protocols. Protocol A: papaverine; protocol B: PGE1; and protocol C: trimix (papaverine, phentolamine and PGE1). Patients were followed up clinically, sonographically and by laboratory investigations for 6 months to evaluate the occurrence of side effects. Group II included 21 patients presenting to our department for the first time with a complication of intracavernous injection pharmacotherapy (ICI) initiated elsewhere. In all, 168 patients of group I completed the study. Patients on papaverine had the highest incidence of complications concerning prolonged erection, subcutaneous hematoma and penile fibrosis. Postinjection penile pain was observed more with groups B and C than group A. No systemic side effects were reported. Duplex ultrasound was beneficial in detecting mild clinically impalpable fibrosis. In total, 10 patients of group II presented with prolonged erection, seven with penile fibrosis, three with cavernositis and one with intracavernous needle breakage. We conclude that although ICI therapy is an effective second-line treatment option, patients on a self-injection program should be followed up both clinically and sonographically both at the initiation phase and on regular follow-up visits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
