Introduction: Hypertension is an overwhelming finding in chronic kidney disease (CKD), but data on hypertension prevalence in acute kidney injury (AKI) are scarce. The aim: The study aimed to assess the prevalence of hypertension in patients with AKI regarding its cause: prerenal, renal, or postrenal.. Material and Methods: We retrospectively analyzed the medical documentation of 215 patients with AKI. Results: Among them, 35% required acute hemodialysis due to either clinical or biochemical indications. Prevalence of hypertension was 70%, with the highest rate in post-renal AKI (85%), followed by renal AKI (75%) and pre-renal AKI (30%). Dialyzed patients were older, had higher blood pressure, and required more hypotensive drugs. Conclusions: Hypertension is prevalent in AKI; however, it depends upon its origin. Uncontrolled hypertension, together with edema and pulmonary congestion are the indications for dialysis initiation. However, caution should be exercised during dialysis to avoid hypotensive episodes.
