title: [Causes of erectile dysfunction after transurethral resection of hyperplastic prostate and its prophylaxis].
abstract: The study was made of 60 sexually active patients with prostatic hyperplasia after monopolar transurethral operations (mean age 61.3 years). 30 patients entered a control group, 30 ones--the study group. The latter received 10 mg vardenafil each other day for 7 weeks after the intervention. The patients filled in questionnaire, underwent dopplerography and electromyography of the penis. Questionnaire said that erection was worse after operation in 6 (20%) patients (p < 0.01) of the control group and none of the study group. The latter also showed better circulation. All the men with postoperative erectile dysfunction (ED) had electromyographic signs of impaired autonomic innervation of the penis. Thus, ED after transurethral operations for prostatic hyperplasia is primarily neurogenic and is seen in 20% operated patients. Early vardenafil therapy is effective in prevention of postoperative ED.
