When a patient is diagnosed with urolithiasis, dietary adjustments are advised based on the specific type of kidney stone. This guidance comes from the head of the urology department at the Scientific Center No. 2 of the Russian Scientific Surgical Center, Dr. BV Petrovsky, a highly experienced urologist. The emphasis is clear: stone composition matters for effective management.
The key point is that kidney stones differ in chemical makeup. They fall into categories such as oxalate stones, which contain calcium salts and oxalic acid; urate stones, formed from uric acid salts; and phosphate stones, composed of phosphoric acid salts. Each stone type benefits from tailored dietary patterns designed to reduce recurrence and support overall kidney health.
For oxalate stones, a higher fluid intake is essential, with a daily goal of about 2 to 2.5 liters. In some cases, limiting certain foods is recommended to minimize oxalate load. Specific items to monitor include dairy products, salty snacks, chocolate, figs, currants, blueberries, sweets, jam, candy, cocoa, and strong coffee. The aim is to strike a balance between hydration and oxalate control while maintaining appetite and nutrition.
In the case of phosphate stones, the diet emphasizes the consumption of robust, savory dishes that support calcium metabolism and urinary pH balance. It is beneficial to pay attention to fruits, vegetables, and berries that act as natural diuretics. Examples include watermelon, eggplant, bananas, pears, cantaloupe, strawberries, cabbage, cranberries, gooseberries, carrots, lettuce, currants, zucchini, and dill. These foods help promote urine flow and may assist in reducing mineral saturation.
For urate stones, the approach prioritizes lean protein sources and careful selection of dairy and grain-based foods. Young animal meats and certain cheeses with high salt content are generally avoided, and legumes are kept in check. The recommended intake shifts toward lean meats, fish, cereals, and soups, paired with a hydration strategy that supports stone dissolution and prevents crystal formation. On occasion, it can be helpful to include fasting days every seven to ten days, during which dairy products, vegetables, and fruits are consumed, while fluid intake remains elevated to maintain urine dilution.
Understanding symptoms, diagnostic pathways, and treatment options for urolithiasis helps patients engage in informed conversations with their healthcare team. Contemporary management focuses on personalized dietary plans, hydration strategies, and, when appropriate, medical or interventional therapies. This article summarizes how stone type guides dietary recommendations and overall kidney health, reflecting current clinical practice and research in urology.
