Abstract

Hypothesis / aims of study 
PDE5Is are the first line of conservative treatment for ED in general, and an effective treatment for neurogenic ED also, such as SCI individuals. Based on that, a real life cohort study was performed to evaluate the adherence to PDE5Is as well as the dropout rate, almost 10 years after the initiation of treatment.
Study design, materials and methods 
97 SCI patients suffering from ED that were treated with PDE5Is were evaluated in 2015. Concomitant
cardiovascular diseases, hormonal and psychiatric disorders were excluded. Efficacy was evaluated with IIEF5 and SEP2 & SEP3 questions.
We re evaluate our data now in order to assess the adherence to PDE5Is, almost 10 years after the initial treatment.
Results 
10 years after the initial treatment, we collected data from 81 patients out of the original 87 responders.

From the sildenafil group, 18 out of 31 responders are still on, 6 on daily us tadalafil, 1 on intra cavernosal
injections (ICI), 1 died, 2 were lost in follow up, 2 are off treatment due to lack of sexual partner and 1 stopped the medication due to other comorbidities.

From the vardenafil group, 5 out of 13 patients  are still on therapy, 2 have changed to sildenafil, 2 on  daily tadalafil, 1 on ICI, 1 without partner and 2 patients have stopped due to comorbidities..

From the avanafil group, 3 out of 7 patients are still on treatment, 1 have changed to sildenafil and 2 on daily tadalafil.

From the on demand tadalafil group, 7 out 22 patients are still on treatment, 5 have changed to daily tadalafil, 2 on sildenafil, 2 were lost in follow up, 1 died, 1 on ICI, 2 don't have a sexual partner and 2 stopped due to other comorbidities.

From the daily tadalafil group, 9 patients are still on, 1 died, 1 on ICI, 2 have changed to sildenafil, 1 underwent penile prosthesis implantation and 1 stopped the medication due to other comorbidities.
Interpretation of results 
After almost 10 years of follow up, the majority of our SCI patients remained on PDE5 inhibitors, either the one prescribed initially or a different one. The medication dropout rate, in our cohort, is approximately 20%, while other comorbidities and lack of sexual partner were the major reasons for withdrawal.
Concluding message 
PDE5Is consist the first line of conservative treatment for ED. They are very well tolerated by men with neurogenic ED, especially by men with SCI, which is depicted by the high level of adherence they demonstrate during the years.
