To review the current literature on early penile prosthesis implantation in patients with refractory ischemic priapism (IP).
A systematic search for the terms "penile prosthesis", "priapism", "impotence", "fibrosis", "downsized prosthesis cylinders", and "patient satisfaction" has been carried out in PubMed, EMBASE, Cochrane, SCOPUS and Science Citation Index databases.
Cavernosal tissue damage in IP is time related. Conservative measures and aspiration with or without intracorporeal instillation of α-adrenergic agonists are usually successful in the early stages. Shunt surgery in patients remains debatable, as the lack of response to aspiration and instillation of α-adrenergic agonists indicates that irreversible changes in the cavernosal smooth muscle are likely to have already occurred. Immediate penile prosthesis implantation in patients with refractory IP settles the priapic episode, maintains the long term rigidity necessary to engage in penetrative sexual intercourse and prevents the otherwise inevitable penile shortening. Although complication rates after penile prosthesis implantation in acute priapism are higher than in virgin cases, they are still lower than after implantation in patients with severe corporal fibrosis due to chronic priapism. Regardless of the complication rates, penile prosthesis implantation in refractory IP should be preferred as it allows the preservation of penile length, which is one of the main factors influencing postoperative patient's satisfaction following surgery.
回顾目前关于难治性缺血性阴茎异常勃起(IP)患者早期阴茎假体植入的文献。
在PubMed、EMBASE、Cochrane、SCOPUS和科学引文索引数据库中,对“阴茎假体”“阴茎异常勃起”“阳痿”“纤维化”“小型化假体柱体”和“患者满意度”等术语进行了系统检索。
IP中的海绵体组织损伤与时间相关。保守措施以及在有或没有体内注射α-肾上腺素能激动剂的情况下进行抽吸,在早期通常是成功的。患者进行分流手术仍存在争议,因为对抽吸和注射α-肾上腺素能激动剂无反应表明海绵体平滑肌可能已经发生了不可逆的变化。难治性IP患者立即植入阴茎假体可解决阴茎异常勃起发作,维持进行插入式性交所需的长期硬度,并防止不可避免的阴茎缩短。尽管急性阴茎异常勃起患者阴茎假体植入后的并发症发生率高于初次植入者,但仍低于慢性阴茎异常勃起导致严重海绵体纤维化患者植入后的并发症发生率。无论并发症发生率如何,难治性IP患者应首选阴茎假体植入,因为它能保留阴茎长度,而阴茎长度是影响术后患者满意度的主要因素之一。
