MRI of the penis

British Journal of Radiology (Impact Factor: 2.03). 11/2012; 85(special_issue_1):S86-S93. DOI: 10.1259/bjr/63301362


MRI of the penis is an expensive test that is not always superior to clinical examination or ultrasound. However, it shows many of the important structures, and in particular the combination of tumescence from intracavernosal alprostadil, and highresolution T2 sequences show the glans, corpora and the tunica albuginea well. In this paper we summarise the radiological anatomy and discuss the indications for MRI. For penile cancer, it may be useful in cases where the local stage is not apparent clinically. In priapism, it is an emerging technique for assessing corporal viability, and in fracture it can in most cases make the diagnosis and locate the injury. In some cases of penile fibrosis and Peyronie's disease, it may aid surgical planning, and in complex pelvic fracture may replace or augment conventional urethrography. It is an excellent investigation for the malfunctioning penile prosthesis.

    ABSTRACT: Introduction We reviewed retrospectively the use of penile prostheses, including the indications and complications of penile prosthesis surgery. Methods We identified publications and the reported advances in penile prosthesis surgery between 1987 and 2012 in Pub-Med, and published information from American Medical Systems, Inc. (Minnetonka, MN, USA) and Coloplast Corporation (Humlebaek, Denmark), using the keywords ‘penile prosthesis’, ‘erectile dysfunction’, ‘mechanical reliability’, ‘complications’ and ‘infection’. Results We describe the novel indications for the use of penile prostheses, the significant advances in implant designs with improved mechanical reliability, the changing landscape of device infection, and the current management of complications. Sixty-eight publications with a grade A, B and C level of evidence are cited. Conclusion The clinical indications to implant a penile prosthesis have expanded beyond organic erectile dysfunction. With the many different devices currently available, the choice of which device to implant can be tailored based on an individual’s unique medical conditions, manual dexterity and expectations, and surgeon preference. There must be a conscious effort to prevent device infection, in the light of the development of increasingly virulent organisms. Penile prosthesis surgery is an integral part of the treatment of erectile dysfunction when non-surgical options fail or are contraindicated.

    ABSTRACT: Introduction: Erectile dysfunction (ED) affects over 150 million men worldwide. Oral phosphodiesterase-5 (PDE5) inhibitors are currently used as a first-line therapy and a second-line therapy with either intracavernosal (Caverject) or intraurethral (MUSE) alprostadil is required for a few men who show poor response or intolerance to PDE5 inhibitors. Areas covered: This article reviews the pharmacology, pharmacokinetics, medical applications, efficacy and safety of alprostadil in the treatment of men with ED. The goal of this article is to review the currently published clinical data of alprostadil to establish its potential role in managing men, in particular, those who fail to respond to traditional PDE5 inhibitors. Relevant articles and abstracts were reviewed from PUBMED and conference proceedings. Expert opinion: Alprostadil, a synthetic form of prostaglandin E1, is used as second-line therapy in managing men with ED. It has a unique role in men with ED secondary to diabetes and ED secondary to radical pelvic surgery (e.g., radical prostatectomy). In view of these new indications, the role of alprostadil is being redefined. Both intracavernosal and intraurethral alprostadil are approved for use in all countries, and following positive results from recent Phase III trials, topical alprostadil has gained approval in Canada.
