Abstract

Management of obstetrical acute renal failure remains a challenging task. We present data of 100 cases of obstetrical-related acute renal failure of 3-year duration (2007-2009) from Department of Nephrology & Hypertension, Lady Reading Hospital, Peshawar, Pakistan. The study is aimed to look at overall mortality and relationship of oliguria/anuria at presentation to dialysis dependency and renal cortical necrosis (RCN). Evaluation of comorbidity to dialysis dependency and RCN was also considered. While 91 Patients required hemodialysis, 9 were managed conservatively, 57 were dialysis dependent whereas 43 remained dialysis independent on discharge, 47 Patients had oliguria, 30 had anuria, and 23 had an output of > 800 mL per 24 h on admission. RCN was seen in 30 cases, all biopsy confirmed, among these, 26 cases (86.67%) were associated with oliguria/anuria and dialysis dependency right from the beginning (p < 0.0001). However, four (13.33%) with RCN had output > 800 mL per 24 h but remained dialysis dependent. Our data showed that out of 30 Patients who presented with anuria, only 10 Patients (33.33%) were dialysis independent on discharge, whereas out of 47 oliguric Patients, 21 Patients (44.6%) were dialysis independent upon discharge. Thus dialysis dependency does not correlate with anuria or oliguria at presentation (p = 0.133). Mortality of 7% was recorded, 23% were discharged with normal renal function. Septicemia, operative interventions, retained product of conception, post-partum hemorrhage, and RCN remained important comorbid conditions with regard to survival and dialysis dependency.
