title: What is the current role of intracavernosal injection in management of erectile dysfunction?
abstract: The emerging of intracavernosal injection (ICI) of vasoactive materials was a major breakthrough in the treatment of erectile dysfunction (ED). However, the current state and future direction of ICI role in the armamentarium of diagnosis, prevention and treatment of ED are not well defined. The aim of this study was to address the current place of ICI in the armamentarium of ED diagnosis and treatment. An English-language MEDLINE review for the utilization of 'intracavernosal injection & erectile dysfunction' was performed from 1990 to present time. Four hundred forty-eight articles were analyzed and classified according to the current utilization of ICI in the following conditions; diagnosis of ED, phosphodiesterase-5 inhibitor (PDE5I) non-responders, diabetes, post radical prostatectomy (RP), stem cells and gene therapy, new intracavernosal drugs, adverse effects and couple satisfaction. This paper is not a standard systematic review; it is eventually a literature review of original peer-reviewed manuscripts and clinical trials reported in Medline. The comprehensive analyses of all the reviewed data were not possible as the level of evidence for utility of ICI in each topic was not available. Current date have established the role of ICI of vasoactive materials as a very common alternative domain in treatment of severe ED particularly in diabetic patients, post-RP, PDE5I non-responders. Further, new studies have denoted the potential future role of intracavernosal treatment for ED in the era of stem cells and gene therapy. ICI of vasoactive material continues to be a highly effective and safe treatment tool for men with wide varieties of ED etiologies. Several experimental and clinical studies are currently investigating new ICI materials. Hopefully in the near future, we might witness evolved molecules and innovative strategies that could help to treat ED patients with different etiologies.
