RÉSUMÉ
Background: Acute kidney injury (AKI) is defined as abrupt and rapid decline in renal filtration function. We have studied cases of AKI in which there was no primary renal involvement. Materials and methods: A hospital based retrospective study of 50 indoor patients was carried out at B J Medical college and Civil Hospital, Ahmedabad to study the cases of acute kidney injury in patients with no primary kidney involvement and their incidence with relation to age, gender, comorbidities, substance abuse and treatment modalities. Results: Total 50 patients of acute kidney injury were analyzed. Peak incidence was found in fourth decade with overall male: female ratio 2:1. The most common etiology was acute gastroenteritis 24% (n=12) followed by infections 40% (n=20). Most of the patients 28% (n=14) who presented with renal failure on admission, resolved with proper fluid resuscitation and antibiotics. Hemodialysis was required in only 6% (n=3) of the patients. Conclusion: Acute gastroenteritis was the most common etiology of acute kidney injury in our study with median age of 45 years with male preponderance.
