Final answer:
The best management for calcium oxalate stones in a patient with ileal resection is Potassium citrate which helps prevent new stone formation by increasing urinary citrate and alkalinizing the urine.
Step-by-step explanation:
Patients with ileal resection may develop calcium oxalate stones due to malabsorption issues that lead to increased oxalate absorption and excretion into the urine. Preventive measures for kidney stones resulting from oxalate accumulation include dietary modifications and potential pharmacological interventions. For instance, reducing intake of oxalate-rich foods, such as chocolate, nuts, soybeans, rhubarb, and spinach, and ensuring an adequate intake of dietary calcium can help. Additionally, maintaining hydration to achieve 2 to 2.5 liters of urine output per day is important.
In terms of medication, Potassium citrate is often used to help prevent stone formation by alkalinizing the urine and reducing the saturation of calcium oxalate. This medication serves to increase urinary citrate excretion, which can bind to calcium and prevent the formation of stones. Hydrochlorothiazide, a thiazide diuretic, is used to treat kidney stones by reducing urinary calcium excretion. Thus, the answer to managing calcium oxalate stones in a patient with an ileal resection is (C) Potassium citrate, to help prevent new stone formation.
