This case-control study supports the findings that retroperitoneal fibrosis persists longer than previously thought, and progression might even occur. Formerly uninvolved organs might become included in the process despite regression of the layer, leading to considerable problems if the condition is not treated in institutions familiar with this complex disease. We advocate a moderated follow-up scheme, as in the case of ordinary abdominal aortic aneurysm, and the need for long-term surveillance of inflammatory aneurysms.

Recent implant crises have highlighted the need for robust registries. This article argues the importance of securing at least 90 percent data capture, which is achievable through the opt-out consent model. Since adopting this model, the Australian Breast Device Registry has increased data capture from 4 percent to over 97 percent. Simultaneously, it is important to foster international collaboration from the outset to avoid duplication of efforts and enable the development of effective international early warning systems.
