Background: Pregnancy-related acute kidney injury (PR-AKI) is a rare yet serious problem during pregnancy. In the recent years, the incidence of PR-AKI has decreased in developed countries to only 1% to 2.8%. However, PR-AKI is still frequent in developing countries. The true incidence of obstetrics related AKI in developing countries like Pakistan and the change in incidence is not much known. The aim of this study is to explore the magnitude of acute kidney injury in pregnancy in our setup.

Objective: To determine the frequency of pregnancy related acute kidney injury.

Study Design: Cross sectional study

Place and Duration of Study: Department of Obstetrics and Gynecology, Saidu Group of Teaching Hospitals Swat from 1st April 2019 to 31st March 2020.
