Within 10 years of sling placement, about 1 in 20 women undergo subsequent surgery to revise their mesh, in which the mesh is cut or partially excised ( Obstet Gynecol . 2019;133:1099-1108). Translabial ultrasound (TLUS) has been described as a sensitive technique for viewing MUS, although few studies have evaluated its ability to view surgically revised MUS ( Radiology . 2018;289(3):721-727). Understanding the anatomy of the MUS is critical to urologists and urogynecologists striving to optimize management of patients presenting with lower urinary tract symptoms and history of MUS. To assess the clinical utility and reliability of TLUS as a diagnostic tool in its detection of MUS discontinuity, we conducted a retrospective analysis on patients who underwent TLUS at a tertiary care center between September 2017 and May 2020 for indication of lower urinary tract symptoms and history of MUS placement. Performance of TLUS was evaluated by comparing findings with operative or clinical records. Among the 81 women included, detection of MUS revision, which was defined as a discontinuity in sling material, had a sensitivity of 84.6% and specificity of 97.1%. Translabial ultrasound is an inexpensive, nonirradiating, and noninvasive modality that is effective at visualizing MUSs. It is a reliable identifier of previous MUS revision, in which it detects a midline discontinuity of the hyperechoic mesh with an average 10 mm gap.</p>","PeriodicalId":49116,"journal":{"name":"Ultrasound Quarterly","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10065043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To simulate the blood perfusion characteristics of human renal cell carcinoma (RCC) longitudinally in the process of tumor growth, multimodal ultrasound examination was performed on 40 orthotopic xenograft RCC mouse models. According to tumor maximum diameter ( d ), tumor growth progress was divided into 3 steps: d ≤ 5 mm, 5 mm < d ≤ 10 mm, and d > 10 mm. Color Doppler flow imaging (CDFI), superb microvascular imaging (SMI), and contrast-enhanced ultrasound were administered to monitor tumor perfusion characteristics. The abundance of tumor vascularity on CDFI and SMI was divided into grades 0 to III in ascending order, and their distribution range was categorized into types I to IV. As a result, heterogeneous echogenicity and irregular shape were more common in tumors d > 10 mm than those d < 10 mm ( P < 0.001 for both). Tumor perfusion grade and type on both CDFI and SMI made statistic difference among different growth steps, with higher ratio of hypervascular characteristic in bigger ones (all P < 0.05). Tumor in the same growth step had a higher perfusion grade on SMI than that on CDFI ( P < 0.001). On contrast-enhanced ultrasound, heterogeneous enhancement was more common in those >10 mm ( P < 0.001).
