[Small-dose vardenafil restores erectile function after penile surgery].

Objective:To investigate the impact of penile surgery on the erectile function of the patient and to evaluate the role of small-dose vardenafil in restoring the impaired penile erection.Methods: Sixty cases of penile cavernosum surgery were equally and randomly divided into a vardenafil and a control group,the former treated 5-7 days after surgery with 10 mg vardenafil every other day,while the latter given vitamin E at 100 mg once a day,both for 12 weeks.The penile erectile function of the patients was evaluated with the IIEF-5 questionnaire before surgery and at 3 and 6 months after vardenafil medication.Results: The mean IIEF-5 scores of the vardenafil group were 18.83 ± 2.98 and 20.13 ± 2.98 at 3 and 6 months after vardenafil medication,significantly higher than 14.21 ± 3.62 before surgery(P0.05),while that of the control group was significantly decreased at 3 months as compared with the preoperative score(13.38 ± 2.82 versus 15.80 ± 3.02,P0.05).The vardenafil group showed the highest IIEF-5 score after surgery(P0.05).Conclusion: Long-term administration of small-dose vardenafil after penile surgery helps to restore and maintain penile erectile function.
