The diagnosis and treatment of patients with pulmonary renal syndromes or any rapidly progressive glomerulonephritis is a medical emergency. Patients should be hospitalised to allow for rapid diagnosis and treatment. Urgent consultation with a nephrologist is essential to expedite diagnosis and treatment, as lung haemorrhage can be rapidly fatal and earlier treatment may prevent irreversible renal destruction. If treatment is delayed, the chances of renal recovery are low. So, where clinical suspicion is high, it may be appropriate to begin treatment before the results of diagnostic testing are available.
