Urethral stones drinking cola may promote the discharge of stones, but it is not that drinking cola can cure stones, but after drinking cola will increase the amount of body fluids into the body, increasing the volume of urine to play the role of urine flushing stones out. At the same time, cola is a drink with high sugar content, which can play the role of osmotic diuretic after entering the body, increasing the volume of urine to discharge stones, but not cola itself has the function of dissolving stones or discharging stones. The effect of drinking cola and water is the same, drinking the same amount of water to produce more urine, through the flushing of urine will be carried out of the body by stones. However, for patients who have phosphate stones in their bodies, they need to reduce cola because cola is a carbonated drink that can lead to an increase in bicarbonate when drunk into the body, which can increase the probability of having phosphate stones. Patients with stones need to refrain from taking large amounts of cola for a long time, as cola can lead to a higher probability of stone development, but during stone removal, they need to drink more water and urinate more, and drinking more cola for a short period of time can play a diuretic role to promote stone removal.
