Abstract
Introduction: Acute kidney injury (AKI) is defined as a rapid loss of kidney function occurring over few hours or days. In intensive care unit settings, acute kidney injury (AKI) is a very prevalent condition as most of the patients who are admitted in intensive care units are critically ill. The incidence of acute kidney injury is increasing throughout the world mainly because of aging population and comorbidities which are associated with aging. In intensive care unit settings, the incidence of AKI may reach up to 67%. Though AKI effects depend on clinical situation yet associated with high morbidity and mortality. Objective: To determine the frequency of etiology of acute kidney injury in medical intensive care unit of KRL Hospital. Setting: Medical ICU, KRL Hospital, Islamabad. Duration: six months from 17th May 2017 to 17th November 2017. Study design: Descriptive case series. Material and method: In this study 118 patients were observed. After screening and application of exclusion criteria, a total of 118 patients who were fulfilling the inclusion criteria were selected as the study sample and were included in the final analysis regarding prevalence of risk factors associated with AKI. AKI was further classified using acute kidney injury network (AKIN) classification system. Patient age, gender, serum creatinine, etiology and outcome in form of recovery or mortality was recorded on specific proforma. Results: Overall incidence of AKI in ICU settings in this study was 37.8%(n=118) .Out of 118 patients who had AKI, 59.3%(n=70) were male , whereas 40.7% (n=48) were females. Most common risk factor associated with development of AKI was sepsis secondary to infectious illnesses and 39% (n=46) of the patients who developed AKI were suffering from infectious illnesses. Gastrointestinal, drugs and cardiac causes constitutes the 32.2% (n=38), 18.6% (n=22) and 10.2% (n=12) respectively of the AKI in ICU settings. Conclusion: Our study concludes that the frequency of etiology including infectious causes was 39%, cardiac pathology 10%, GI causes 32%, drugs was 19%.

Summary
Acute kidney injury (AKI) is defined as a rapid loss of kidney function occurring over few hours or days. Acute kidney injury (AKI) is defined as a rapid or abrupt loss of kidney function occurring over few hours or days [1]. The clinical features of acute kidney injury (AKI) are very variable and there may be decrease in urine output or qualitative differences in urine solute concentrations in the absence of oliguria. In 50-60% of the patients diagnosed as having acute kidney injury (AKI), there is no decrease in urine output. Presence or absence of oliguria is related to prognosis of acute kidney injury (AKI). Complications of Acute kidney injury (AKI) include increase potassium level, metabolic acidosis, body fluid imbalance, uremia and patient may require dialysis
