However, infection, erosion, mechanical failure, atrophy, and balloon deterioration cause device malfunction in approximately half of patients by 10 years after implantation. Many patients desire to regain urinary continence and require revision surgery (RS), including device removal and simultaneous or delayed implantation. Patients for whom RS is considered should be examined physically and by interview for signs of infection. Urethral erosion should be assessed using cystoscopy. If there is infection or erosion, all devices should be removed first, and a new device should be implanted several months later. During the RS, after strong adhesion around the urethra, transcorporal cuff implantation is a safe choice. Device removal and simultaneous implantation can be performed in the absence of infection or erosion. If a long time has passed since device implantation, the entire device should be replaced due to device aging and deterioration; however, if the time is short, only the defective component need be replaced. Intraoperative assessment of urethral health is necessary for device removal and implantation. If the urethra is healthy, a new cuff can be placed in the same position as the old cuff was removed from; however, if the urethra is unhealthy, the cuff can be implanted in a more proximal/distal position, or a transcorporal cuff implant may be chosen.

Several guidelines recommend extended PLND for patients with these cancers. However, the therapeutic benefits of extended PLND are unclear. One major reason is that the extent of PLND is not clearly defined. Thus, the working group for standardization of robot-assisted PLND, including nine experienced urologists for PLND in Japan, was launched in January 2023 by the Japanese Society of Endourology and Robotics. This study summarized the discussions to define the individual extent of PLND in urological surgery in a consensus meeting among these experienced urologists. The consensus meeting determined the extent of PLND based on arteries (veins) and anatomical membrane structures rather than a vague concept or approach toward PLND. This concept is expected to allow surgeons to implement the same extent of PLND. Finally, after a total of 10 online web conferences were held, we determined the extent of PLND for the obturator lymph node (LN) area, the internal iliac LN area, the external and common iliac LN area, and the presacral LN area according to the above rules. The extent of PLND suggested here currently does not have a clear therapeutic rationale. Therefore, the extent of our proposed PLND is by no means mandatory. We hope our definition of the extent of PLND will be supported by further evidence of therapeutic benefits for urologic cancers.</p>","PeriodicalId":14323,"journal":{"name":"International Journal of Urology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142035836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
