Your healthcare provider may prescribe Urocrit K for managing kidney conditions like renal tubular acidosis (RTA) with kidney stones, hypocitraturic calcium oxalate nephrolithiasis, or uric acid lithiasis with or without calcium stones. Urocrit K works by increasing how alkaline the blood is, increasing urine pH. Subsequently, greater amounts of citrate are excreted through the kidneys. Urocrit K also increases potassium in the blood and kidneys. The overall effect is that stones are less likely to form in the kidneys.
