A very rare cause of oliguric acute kidney disease: crescentic C3 glomerulopathy

We emphasize the importance of proteinuria evaluation in patients with oligo-anuric AKD even when polyuria phase begins which means that the recovery period of AKD is initiated. Therefore, crescentic C3G should be considered in such patients. Monoclonal gammopathy and genetic factor H defects should be investigated to determine the underlying etiology in C3G patients. Monthly cycles of cyclophosphamide infusion (a total of 6 cycles) are beneficial for these patients.
