JAKARTA - Kidney stones can occur to anyone in various sizes. One of the questions that is often related to kidney stones is related to their expenditure through urine.

Quoted from the Cleveland Clinic, on Thursday, October 9, 2025, kidney stones are solid mass or crystals formed from various substances such as minerals, acids, and salt found in the kidneys. The size of kidney stones can be very small to large, which reaches the size of a golf ball.

This stone is formed when urine contains too many substances and too little body fluids, so the substance crystallizes and forms. Related to the release of kidney stones through urine, it can occur if it is small in size.

The size of the kidney stone that may come out through urine is 3-5 cm. urologist Ryan L. Steiberg said that kidney stones can come out of urine by increasing liquid consumption so that urine production increases.

The process can be assisted with medicines prescribed by doctors to relieve pain and facilitate the release of kidney stones during urine disposal.

If kidney stones try to get out, they will come out on their own with increased hydration. So, a lot of urinating (with a lot of water consumption) to help push the stone out and maybe some medicines can help, "explained Steinberg.

Another way to help the process of removing kidney stones through urine is by consuming lemon juice. This is because lemon contains a sitrate that can prevent the formation of calcium stones and help break down small stones to get out more easily.

Light physical activity, such as walking, yoga, or leisurely cycling can also help remove kidney stones through the urinary tract. However, it is recommended to avoid strenuous exercise that can cause greater pain.

However, if the kidney stone does not come out for six weeks after doing these various methods, it is recommended to carry out medical procedures.

If it doesn't come out in six weeks, it's likely that the kidney stone won't come out alone. So medical action needs to be taken to get it out, "concluded Steinberg.
