Long-term results of therapy with intracavernousal injections and penile venous surgery in chronic erectile dysfunction.

Author information

Urology Section, VA Hospital, Madison, WI.


A follow up study of 603 patients with chronic erectile failure was carried out concerning the long term effects of intracavernous injection therapy with papaverine/phentolamine (n = 172 evaluable) and venous surgery (n = 134 evaluable). Injection therapy was effective in 95.8% of injections. Side effects included prolonged erections in 0.15% of injections and fibrotic palpable indurations in 3.4%. Acceptance of therapy was high among patients and their partners and improvement of self image or partnership was reported in 77.8% and 79.5% respectively. Results of venous surgery were not satisfactory. Only 19.4% of patients achieved sufficient spontaneous erections and 35.1% needed adjuvant injections. Spongiosolysis yielded better results. Patients with neurological impairment, diabetes mellitus, postoperative onset of erectile dysfunction and age above 40 years showed poorer surgical results. Venous surgery should only be offered to a highly selected group of patients.
