Measure
PRN Sildenafil
Placebo QHS (blinded) and sildenafil 100mgs (open-label) as required for sexual relations. The placebo will be omitted on nights that 100mgs is used. Placebo will start within 24-48 hours post-surgery. Placebo QHS and sildenafil and questionnaires: Pts will be offered sildenafil 100 mg to be used before intercourse on an as-required basis. They will be given six 100 mg doses, per month, for a 12-month duration. Each patient in this group will use a placebo pill (blinded) each night, except on a nights that 100mg is taken for the purpose of sexual relations. Patients will be evaluated in the clinic and will complete the questionnaires at baseline (pre-treatment evaluation), 3, 6, 9, 12, 18 and 24 months after the operation. At 12 months postoperatively, all patients will stop treatment. Visits 3, 6, 9, 12, 18, and 24 months will have ±2 week window.
Nightly Sildenafil Arm
Patients will be instructed to take sildenafil 50 mg QHS (blinded) except on nights that they are interested in sexual relations, they will then be instructed to use sildenafil 100mgs (open-label) and skip the 50mg dose. Sildenafil treatment will start within 24-48 hours post-surgery. Sildenafil and questionnaire: Patients will be instructed to take sildenafil 50 mg QHS (blinded) except on nights that they are interested in sexual relations, they will then be instructed to use sildenafil 100mgs (open-label) and skip the 50mg dose. Sildenafil treatment will start within 24-48 hours post-surgery. Patients will be evaluated in the clinic and will complete the questionnaires at baseline (pre-treatment evaluation), 3, 6, 9, 12, 18 and 24 months after the operation. At 12 months postoperatively, all patients will stop treatment. Visits 3, 6, 9, 12, 18, and 24 months will have ±2 week window
Combination Therapy Arm
Trimix combination (Papavarine 30mg/mL Phentholamine 1mg/mL Prostaglandin E1 10 mcg/mL), at initial dose of 5 units (0.05ml) will be given; the first 2 injections will be done in the MSKCC urology outpatient clinic (if needed, the investigator can determine appropriate amount of injections for patient training). Trimix combination (Papavarine 30mg/mL Phentholamine 1mg/mL Prostaglandin E1 10 mcg/mmL) and questionnaires: Intracavernous injections of a trimix combination (Papaverine 30mg/mL Phentholamine 1mg/mL Prostaglandin E1 10 mcg/mL) will be injected three times a week, and sildenafil 50mg taken on the other four (non-injection) nights. Injection therapy can be used for the purpose of sexual relations. Patients will be evaluated in the clinic and will complete the questionnaires at baseline (pre-treatment evaluation), 3, 6, 9, 12, 18 and 24 months after the operation. At 12 months postoperatively, all patients will stop treatment. Visits 3, 6, 9, 12, 18, and 24 months will have ±2 week window.
