Vasoactive intracavernous pharmacotherapy--the nursing role in teaching self-injection therapy.

Our physician-nurse team management of a program in vasoactive intracavernous pharmacotherapy to treat male impotence has provided a high degree of patient and partner satisfaction. Nurses participate in the assessment of the ability of a patient or partner to master the self-injection technique, and the potential of a couple for compliance with and commitment to the program, all of which are key factors for successful home therapy. A nurse also teaches the self-injection technique. Audiovisual materials and handouts are used as teaching aids to ensure that complete and consistent information is given. The patient or partner is required to perform a self-injection under nursing supervision before a prescription for home use written. Initial followup visits are scheduled with a nurse at 1 to 2-week intervals. At these visits the nurse identifies possible patient errors in self-injection technique, dose or frequency, and answers questions about the therapy. After the couple has mastered and is comfortable with home injection, followup appointments are scheduled with the physician at 4-week intervals to monitor for possible changes in response to treatment and for an examination of the phallus.

Intracavernous drug-induced erections in the management of male erectile dysfunction: experience with 100 patients.

A total of 100 men with organic impotence underwent a trial of intracavernous drug-induced erections with a mixture of papaverine (25 mg./ml.) and phentolamine (0.8 mg./ml.). The response rates, that is functional erections, were 100 per cent in patients with neurogenic impotence, 65.7 per cent in those with vasculogenic impotence, 90 per cent in the undetermined group and 64.7 per cent in the neurogenic/vascular impotence group. Of the responders 79.5 per cent elected to practice self-injection as a method to restore erectile function. The dose required to obtain functional erections in the purely neurogenic impotence group was significantly lower than that required in other groups. Complications were few and included 4 patients with sustained erections that required intervention. Intracavernous injection of vasoactive drugs appears to have promising value in the treatment and differential diagnosis of erectile dysfunction.

Evaluation of new nonadhesive urostomy system.

The new Vance nonadhesive urostomy system has several advantages over established systems, including ease of assembly, cleanliness, large and less visible storage capacity, and security from leakage. We studied 44 patients using this system, including those who were previously satisfied with more established ostomy systems and those with stomal problems. We found the new system to be superior in most of the patients.
