Abstract

CALDERON VALVERDE, Gabriel  and  CHEN, Yu Ya Lin. Hydronephrosis as an unusual and distracting manifestation in the diagnosis of ANCA-positive vasculitis. Rev. argent. reumatolg. [online]. 2023, vol.34, n.1, pp.37-39. ISSN 0327-4411.  http://dx.doi.org/10.47196/rar.v34i1.717.

Obstructive nephropathy is considered an unusual presentation in ANCA-associated vasculitis. The following case describes a 38-year-old male with granulomatosis with polyangiitis and unilateral hydronephrosis, as well as a literature review. A 38-year-old male with an unremarkable medical background presents with a 3-week history of odynophagia, constitutional symptoms and anuric kidney injury. Initially managed as an obstructive nephropathy due to a left hydronephrosis finding, the patient eventually develops a diffuse alveolar hemorrhage, acute respiratory distress and perishes due to granulomatosis with polyangiitis.

Obstructive nephropathy is an unusual manifestation of ANCA-associated vasculitis. Diagnostic suspicion is important in these multisystem pictures so as not to delay immunosuppressive treatment together with the rest of the required therapies.

Keywords : ANCA-associated vasculitis; granulomatosis with polyangiitis; hydronephrosis.
