Importance Vaginal fibroblast function is altered in people with pelvic organ prolapse. Thus, it is important to study vaginal fibroblasts to better understand the pathophysiology of prolapse. Objective This study aimed to compare 3 culturing methods of primary vaginal fibroblasts. Study Design This was an in vitro study. Patients who were undergoing surgery for vaginal prolapse were recruited. Excess vaginal epithelial tissue that would have otherwise been discarded was collected. The vaginal fibroblasts from each participant were cultured via (1) 3-hour digest, (2) coverslip, and (3) gelatin-coat methods. Differences in the efficiency of cell isolation, expression of known fibroblast-associated genes, and cellular function were compared between the 3 methods using one-way analysis of variance and Tukey test for post hoc pairwise comparisons ( P < 0.05). Results Five patients with pelvic organ prolapse were recruited. Fibroblasts cultured via the 3-hour digest method became confluent within 3–5 days in a 100-mm dish compared to 2–3 weeks in a 6-well dish for the coverslip and gelatin-coat methods. Cells from all culture methods expressed similar amounts of vimentin and α smooth muscle actin. There were no significant differences in morphology; gene expression levels of MMP1 , MMP2 , ACTA2 , COL1A1 , COL3A1 , and LOXL1 on qPCR; cell viability; proliferation; and migration between the 3 culturing methods. Conclusion Culturing primary vaginal fibroblasts via the 3-hour digest, coverslip, and gelatin-coat methods similarly resulted in reliable primary vaginal fibroblast growth and function.

Importance A sequelae of the removal of pelvic organ prolapse (POP) transvaginal mesh products from the U.S. market is that current and future women's health providers may be unfamiliar with mesh products historically used to treat pelvic floor disorders. Objectives Our goal was to create an easily accessible resource to address this knowledge gap. Study Design An online database of mesh products used to treat POP and urinary incontinence was created with information, photographs, and videos collated from internet searches; manufacturer materials; and other primary sources. The database was then linked to a free smartphone application. Results This smartphone application includes, to the best of our knowledge, all mesh products used in the United States for the treatment of POP and stress urinary incontinence through December 2020. Included in the application are product descriptions of mesh color, size, design, and attachment points. Photographs and videos, when available, are included. The application is organized by mesh product name, but it is also searchable by other categories, such as manufacturer name and color. To download the application to a smart phone, go to vaginalmeshcatalogue.glideapp.io/ on a web browser or access via the QR code. Once the website is loaded, you can interact with the mesh catalog as a website or save it to the phone's home screen as an application. Conclusions Health care providers of all experience levels can use this free application for educational and clinical purposes to better understand patients' histories, improve preoperative planning, and enhance patient counseling.
