Characterization of the host inflammatory response following implantation of prolapse mesh in rhesus macaque

The host response to mesh consists predominantly of activated, proinflammatory M1 macrophages at 12 weeks postsurgery. However, this response is attenuated with implantation of lighter-weight, higher-porosity mesh. While additional work is required to establish causal relationships, these results suggest a link among the host inflammatory response, mesh textile properties, and clinical outcomes in the repair of pelvic organ prolapse.
