The host reaction to collagen sling over time. Typical fields of views taken from H&E (hematoxylin and eosin) and MT (Masson’s trichrome) stained sections demonstrating de novo tissue deposition in the interstitial regions of retrieved sling materials. Sections are taken in the frontal plane and fields of view are taken in the mid-urethral regions. (A) Longer axes of slings are oriented horizontally. C: Collagen sling residuals. The scale bar for H&E images is 1 mm. The scale bar for MT images is 200 μm. (B) Results for percentage of total area occupied by collagen sling threads using the point counting method in the suburethral area. (C) Percentage of total area occupied by interstitial collagen in the suburethral area was significantly greater at 12 months. (D) Thickness of the fibrous capsule around collagen slings declined significantly by 12 months.
