This section includes three papers, two of which describe the use of drug treatment for erectile dysfunction in special situations. The authors from New York and Chicago write about sildenafil in patients with a penile prosthesis in situ. Authors from Zurich have used apomorphine in patients with spinal cord injury and erectile dysfunction. It is often helpful to readers with an interest in the area of erectile problems to explore the use of commonly prescribed drugs in somewhat less common situations.OBJECTIVETo assess the efficacy of sildenafil in increasing penile glans tumescence and improving patient satisfaction in men with a penile prosthesis, as this remains a major treatment for erectile dysfunction but a common complaint is the lack of glans engorgement.PATIENTS AND METHODSTo determine whether sildenafil combined with a penile prosthesis improves satisfaction, patients used an implant alone for at least 1 month, after which they completed the International Index of Erectile Function (IIEF) questionnaire. The same patients were then given sildenafil citrate and completed the IIEF questionnaire after using the sildenafil/implant combination.RESULTSPatients who responded to sildenafil with glans engorgement reported significantly greater satisfaction scores than with an implant alone.CONCLUSIONWe currently offer sildenafil citrate after implantation to all men who have a penile prosthesis placed.

To our knowledge this study is the largest published, single center cohort of patients treated with injection and followed for an analysis of dropout rates. Based on study data a reduction in dropout rates may be achieved by keeping the cost of therapy low, and ensuring patient and partner education as well as continued support throughout treatment.
