Is renal cortical necrosis a disappearing entity in obstetric acute kidney injury in developing countries : our three decade of experience from India? Context: Obstetrical complications are the commonest causes of Renal Cortical Necrosis (RCN). However, the overall incidence of RCN in obstetric acute kidney injury in developing countries has been decreasing in recent years. The aim of this study was to evaluate the changing profile of RCN in obstetric AKI over the last three decades. This single center study included patients with biopsy proven renal cortical necrosis over a period of 32 years from 1982 to 2014. The diagnosis of RCN was suspected in patients with prolonged AKI (>4 weeks) with absolute anuria in the setting of hemorrhage, hypotension and sepsis; and was confirmed by renal biopsy. The changing pattern in the incidence, etiology and outcome of RCN in patients with obstetric AKI was compared in the three study periods, namely 1982-1991, 1992-2002 and 2003-2014. Over a period of 32 years, RCN was diagnosed in 15/259(5.8%) cases of obstetric AKI. Diffuse and patchy cortical necrosis were noted in 8(53.3%) and 7(46.7%) patients, respectively. RCN occurred in 17%(11/65), 2.4%(3/125) and 1.44%(1/69) patients in 1982-1991, 1992-2002 and 2003-2014, respectively. Septic abortion was commonest cause of RCN in the first two study periods but no case was observed in last decade. The decrease in incidence of RCN over the three decades was statistically significant (p-value < 0.001). Maternal mortality decreased to zero in 2003-2014 from 72.7% in 1982-1991.

The incidence of RCN in obstetric AKI in developing countries has declined low enough to label it as a disappearing entity. Final Decision: yes
