Relatively quick. In general your renal arteries 'recover' right away, e.g. If you had renal hypertension due to stenosis it is resolved with the percutaneous revascularization. The recovery is for the groin access: most people stay overnight and restrict (some) activities for 1-2 weeks. A week is usually sufficient.
Short. Some do these as outpatients, but most admit overnight. Light lifting and activity for 3-5 days is typical if there are no complications.
Few days. My patients stay one night in the hospital. Some doctors send patients home same day. Light activity one week so no bleeding at groin puncture site.
