Over the years penile prosthesis surgery has become increasingly safe owing to improvements such as antibiotic usage, coated devices, and surgical techniques. However, infection remains a dreaded complication during prosthesis surgery. Efforts to minimize risk of infection in the perioperative period have been extensively studied. Herein, we performed a narrative review on preoperative, intraoperative, and postoperative strategies for infection prevention during placement of a penile prosthesis with a comparison of infection prevention strategies to other surgical fields.</p><p><strong>Methods: </strong>A literature review was performed using PubMed and Google Scholar.

The key outcomes were overall improvement, patients reported satisfaction and complication rate.</p><p><strong>Results: </strong>A total of 88 patients between December 2016 and December 2019 have been enrolled in this trial. Improvement was defined as a reduction in pad usage per day (p/d) over 50% compared to baseline. In total, 70 (88%) patients were reported to be improved. Treatment success according to the definition of 0-1 p/d was accomplished in 56 (70%) patients. Urethral erosion, infection or mechanical failure occurred in 4 (5%), 4 (5%) and 1 (1.3%) patient respectively. Explantation of the device was mandatory in 6 patients due to erosion, infection or mechanical failure.</p><p><strong>Conclusions: </strong>In this series, a continence rate of 70% was achieved with an acceptable complication-rate. These results together with a high satisfaction rate demonstrate effectiveness and safety of the Victo system in mid-term follow-up for the treatment of male SUI.</p>","PeriodicalId":23270,"journal":{"name":"Translational andrology and urology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11399051/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142296200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
