Contrast media-induced oliguric renal failure.

Area of Science:

• Nephrology
• Radiology
• Pharmacology

Background:

• Contrast media administration is common in diagnostic imaging.
• Acute kidney injury (AKI) is a potential complication of contrast media.
• Risk factors for contrast-induced nephropathy are not fully elucidated.

Purpose of the Study:

• To report cases of acute oliguric renal failure following contrast media procedures.
• To identify predisposing factors for contrast media-induced renal failure.
• To highlight the incidence and clinical course of contrast media-induced AKI.

Main Methods:

• Retrospective case series of seven patients who developed acute oliguric renal failure.
• Review of patient demographics, pre-procedure conditions, and contrast media used (Diatrizoate meglumine).
• Analysis of the timing, duration, and recovery of renal failure, along with serum creatinine levels.

Main Results:

• Seven patients (average age 63) developed acute oliguric renal failure post-angiography.
• Common predisposing factors included diabetes mellitus, negative fluid balance, renal insufficiency, and hypertension.
• Renal failure onset was within 24 hours, persisting for an average of 72 hours; six patients recovered fully.

Conclusions:

• Contrast media-induced oliguric renal failure may be more prevalent than generally recognized.
• Diabetes mellitus, advanced age, and underlying renal insufficiency are significant predisposing factors.
• These findings underscore the importance of risk assessment before contrast media administration.
