Granulomatosis with polyangiitis (renal manifestations)

Dr Craig Hacking and Dr Henry Knipe et al.

The renal manifestations of granulomatosis with polyangiitis (GPA) (previously known as Wegener's granulomatosis) are occult on imaging, especially when compared to the pulmonary changes. Approximately half of GPA patients have kidney disease at presentation. Granulomatosis with polyangiitis (Wegener granulomatosis), is a multi-system systemic necrotizing non-caseating granulomatous vasculitis affecting small to medium-sized arteries, capillaries and veins.

Clinical presentation

Reduced renal function, proteinuria and haematuria. 


GPA affects the kidneys with the development of necrotising glomerulonephritis in ~60% (range 39-80%) of patients.
