FIGURE 3.

Picrosirius red-stained section under cross-polarized imaging conditions to visualize the alignment of collagen deposition in the interstitial regions of retrieved sling materials. C: Collagen thread, L: Lynx, P: Polypropylene thread in the wing section. Sections are taken in the frontal plane and fields of view are taken in the mid-urethral regions of slings except for 1 year and 3-weeks PP images that were taken from the proximal end-regions of slings. The longer axis of slings is indicated with a double-sided yellow arrow.
