To remove a kidney stone naturally, one would first have to identify the size and position of the stone in the urinary system. Stones larger than 10 mm are generally difficult to pass spontaneously and require surgery. If the stone is blocked in a kidney cavity, it will also be more difficult to pass spontaneously, and waiting too long would allow the stone to grow and make its natural expulsion even more complicated, with a risk of renal colic.
First and foremost, if you have a kidney stone, you should consult your urologist. If the stone is smaller than 10 mm and is located in the lower part of the urinary system, i.e., closer to the bladder, then you have a high probability of being able to pass it naturally and spontaneously.
For certain types of stones, such as uric acid or struvite stones, it is possible to facilitate their dissolution, reduction in size, and expulsion by modulating urine pH. This can be achieved by using alkalizing agents in the case of uric acid, such as sodium bicarbonate or citrate, or acidifying agents like L-methionine for struvite stones. This process, called chemolytic treatment, is always carried out under medical supervision.
Your doctor may recommend an "Expulsive Medical Treatment." This treatment involves prescribing alpha-blocker medications, which will help relax the ureter muscles to facilitate stone passage, as well as pain relievers and drinking plenty of water.
Staying adequately hydrated and engaging in regular physical activity will help naturally eliminate the stone. It may also be useful to take supplements that contain crystallization inhibitors to prevent stone growth or the formation of other stones at the same time.
