Shared-decision making is crucial in today’s society. Although penile prosthesis surgery has had significant improvements regarding technique and materials over the last few decades – with the highest satisfaction rate in erectile dysfunction treatment at present time -, dissatisfaction can occur because of bad preoperative counseling with the creation of unrealistic expectations. This paper includes a small narrative review regarding the most important preoperative variables to be discussed in the preoperative setting. Literature search was conducted in December 2023 using PubMed. Additionally, our own standardized flowchart for preoperative counseling was added. The most important aspects of preoperative counseling include a description of the pathophysiology of erectile dysfunction as well as alternative treatments. Information should be given about which implant categories exist. Additionally, some information about the procedure itself as well as the financial aspect should be communicated. The most frequent and most important complications should be illustrated. Last but not least, the patient’s expectations should be evaluated. Our added standardized flowchart with figure acts as a practical guideline for professionals as well as for patients. Our standardized approach for preoperative counseling emphasizes reasonable postoperative expectations aiming for a well-informed patient with high postoperative satisfaction. Our general strategy is to underpromise and overdeliver.© 2024. The Author(s), under exclusive licence to Springer Nature Limited.
