Intracavernous injections of prostaglandin E1 for erectile dysfunction: patient satisfaction and quality of sex life on long-term treatment.
BACKGROUND
Since the availability of oral type 5 phosphodiesterase (PDE5) inhibitors for the treatment of erectile dysfunction (ED), patients' views on the use of intracavernous injections (ICI) of prostaglandin E1 (PGE1) may have changed.


OBJECTIVE
To assess the satisfaction of patients with long-term ICI.


METHODS
Patients with ED (>18 years old) who had used ICI of PGE1 for at least 3 months were asked to complete the "EASY" (Evaluation de l'Acceptation des injectionS dans la dYsfonction érectile) questionnaire.


METHODS
Overall patient satisfaction with ICI, impact on quality of life, ease of use, satisfaction with the quality of erections, and perceived partner satisfaction.


RESULTS
Overall, 596 questionnaires met our inclusion criteria. Mean patient age was 62.1 years, mean duration of ED was 61 months, and mean duration of ICI treatment was 35 months. Before using ICI, 43% of patients had taken at least one PDE5 inhibitor; 81% discontinued PDE5 for want of efficacy. The overall satisfaction rate with ICI was 78.3%. ICI met expectations each time in 78.6% of patients and at least half the time in 90% of patients; 86% were ready to recommend ICI to friends. Patients noted improvements in their sex life (70.1%), relationship with their partner (50%), quality of life (44.8%), and confidence in attempting sexual intercourse (80.3%). The mean number of injections was 4.4 per month. Most patients (81.1%) found the injections easy to use. The mean score for pain on injection was 2.09/10 and for pain on erection was 2.15/10. Three-quarters of patients (73.1%) thought that their partners were satisfied with ICI.


CONCLUSIONS
Patients on long-term ICI/PGE1 can recover a very satisfying sex life. ICI met patients' expectations in terms of efficacy, ease of use, tolerance, and improved sex life. These results should encourage physicians and patients to use ICI when PDE5 fails, is not well tolerated, or is contraindicated.
