    Author: Chen J, Mabjeesh NJ, Greenstein A.
    Journal: J Urol; 2001 Nov; 166(5):1779-81. PubMed ID: 11586223.
    Abstract:
    PURPOSE: We evaluated the preference of patients with erectile dysfunction who had been effectively treated with a vacuum erection device and then switched to sildenafil. MATERIALS AND METHODS: A total of 52 patients with erectile dysfunction who achieved satisfactory erectile function according to the International Index of Erectile Function (IIEF) while using a vacuum erection device were switched to an increasing dose of sildenafil (range 25 to 100 mg.) until satisfactory erection was maintained at least twice a week for at least 1 month. The 2 treatment methods were not used concomitantly. A total of 36 patients with a mean age of 59 years (range 35 to 77) who claimed to have achieved satisfactory erections with a vacuum erection device and sildenafil reported their preference to continue sildenafil or resume the use of a vacuum erection device, reasons for the choice and any adverse side effects. RESULTS: Of the 36 participants in whom the efficacy of sildenafil was similar to that of a vacuum erection device according to the IIEF scores (mean plus or minus standard deviation 61.6 +/- 10.4 and 62.5 +/- 6, respectively), 12 (33.3%) decided to resume use of a vacuum erection device (group 1) while 24 (66.6%) preferred to continue sildenafil (group 2). There were no statistically significant differences between the groups regarding patient age or the etiology and duration of erectile dysfunction. The increase in the IIEF score while using a vacuum erection device was higher in group 1 than 2, with a mean of 66.75 versus 60.4, respectively (p = 0.002). The adverse side effects of sildenafil were the main reasons for preferring a vacuum erection device. Fewer ejaculatory difficulties, efficacy, comfort and ease of use were the main reasons for choosing sildenafil. CONCLUSIONS: Even in an era of effective oral medication, the vacuum erection device remains a preferred treatment option for a substantial number of patients with erectile dysfunction.
