Patients attending urology specialist clinics contain a large proportion of stone patients, and the pain caused by the disease makes them eager to understand how the lifestyle can prevent the generation and recurrence of stones, now combined with clinical experience to make a little summary, I hope to help the majority of patients. As we all know, with the industrialization of information in the world, people’s lifestyles have also undergone radical changes. The latest studies from China, the United States, Germany, Italy and Japan have shown an increase in the incidence of urinary stones, which is also reflected in the patients attending our urology clinic. First of all, the reduction of fluid intake is one of the most important dietary factors in stone formation. Several studies have been conducted to confirm the correlation between reduced fluid intake and increased stone formation. It is important to note that common soft drinks such as cola can cause a decrease in urine pH and increase the risk of stone formation, but caffeine has a protective effect on stone formation, so stone patients should consume more neutral drinks (e.g. tap water, mineral water with less minerals and fruit/herbal teas) or alkaline drinks (e.g. water rich in bicarbonate). Another dietary factor that contributes to increased stone formation is excessive protein/purine intake. The intake of animal protein (especially meat and seafood) leads to increased urinary calcium and uric acid levels, which increases the risk of stone formation. Obesity is also a risk factor for stone formation, as patients with high BMI (Body Mass Index = weight/height squared) have a tendency to have increased uric acid, urinary sodium/phosphorus, urinary ammonium levels, and decreased pH, all of which can lead to increased stone formation. As the diet of our population becomes increasingly westernized, it is equally important to understand the impact of these factors on stone formation. As doctors, here we also remind patients of the feasible ways to prevent stones: 1. drink >2700ml of water daily 2. add a glass of water before going to bed 3. can consume 2-3 sweet oranges daily, which contain a large amount of sodium citrate, which can melt stones, according to outpatient observations, stones smaller than 6mm have a 61% chance of melting within 3 months.
