It is recommended that patients eat more diuretic foods and fruits, such as apples, pears, peaches, oranges, and especially watermelon, which can produce a large amount of urine, flush the urethra, and possibly carry out small stones. Also, it is important to drink plenty of water every day, more than two liters, especially before going to bed—at least 500 milliliters—so that the urine volume is greater the next morning, making it easier to flush out the stones. Furthermore, patients are advised not to eat spicy and irritating foods, not to drink alcohol, especially strong spirits, and not to eat seafood, as urinary stones can easily lead to symptoms of urinary infection, and consuming these spicy and irritating foods can worsen the symptoms of infection.
