Introduction: Acute kidney injury (AKI) causes 2–5 % of acute care hospital admissions and 20 – 30 % admissions to intensive care unit. AKI may be community acquired or hospital acquired. To evaluate the causes, clinical profile of AKI in this study.

  Material and Methods: it is a cross sectional observational study of 100 patients with AKI. Complete patient history, physical examination, routine and specific laboratory investigations were done to find out the etiology, clinical features and outcome of AKI.

  Results:  Maximum incidence (22%) of AKI was seen in the age group between 25– 34 years. The most common clinical features were vomiting (92%), oliguria (80%), and fever (70%). The incidence of prerenal, renal and postrenal AKI was 20%, 76%, 4% respectively; Malaria (34%) was the predominant cause of AKI in our study. In our study mortality was seen in 10% of the patients, of which most of the patients had septicemia and associated complications like respiratory failure.

  Conclusion: Good survival rate depends on early diagnosis and early intervention.
