Abstract
Acute Phosphate Nephropathy is a clinical and pathological finding characterized by acute and subsequent chronic renal failure following the use of intestinal cleansers containing sodium phosphate. The pathophysiology of Acute Phosphate Nephropathy occurs due to the increase of sodium and water absorption in the proximal tubules due to hypovolemia, and the accumulation of calcium phosphate load in the distal tubules in the collector and distal canals. Renal biopsy findings include acute and chronic tubular damage with tubular and interstitial calcium phosphate deposits. Prevention of Acute Phosphate Nephropathy can be achieved by hydration before and after the use of calcium phosphate in risky patients, minimizing the sodium phosphate dose, and having 12-hour intervals between sodium phosphate applications. In this article, we aimed to present the patients who used sodium phosphate for colonoscopy and developed Acute Phosphate Nephropathy.
