Background: Stroke is serious and often complicated. The aim of this study was to identify the various factors associated with acute kidney injury (AKI) in stroke patients treated atRegional Teaching Hospital of Borgou Alibori (Benin)the in 2024.

Methods: This was a cross-sectional study with prospective data collection from July 1, 2024 to September 30, 2024, carried out in the neurology department of the said hospital and concerned patients admitted for a stroke. Patients at least 18 years of age, hospitalized for a recent stroke (less than one month), with impaired renal function and having given free and informed consent (themselves or the patient’s caretaker) were included. AKI was selected according to KDIGO 2012 criteria. Associated factors were identified and the significance threshold was p<0.05.

Results: Of the 70 patients hospitalized for stroke, 33 had had acute kidney injury and 22 (66.7%) were in stage 1. The mean age of the patients was 60.09 ± 3.97 years and the sex- ratio was 1.34. Factors identified were speech disorders (p=0.028), hypochloremia (p=0.004) and bladder catheterization (p=0.018).

Conclusion: The frequency of renal impairment in patients hospitalized for stroke is high. Many factors are associated with it, and corrective measures are urgently needed to prevent its occurrence.
