Whether bladder stones can be expelled from the body depends on the size of the stones. If the diameter of the bladder stone is less than 7 millimeters, in this case, by drinking more water and urinating frequently, relying on the flushing action of urine, the stones can be expelled from the bladder in most cases. However, if the stone is larger, with a diameter of 1 centimeter or more, it is difficult to expel the stone through conservative treatment and often requires surgical intervention, such as extracorporeal shock wave lithotripsy or holmium laser lithotripsy under cystoscopy to first crush the stone, then expel it through conservative treatment, or remove the crushed stones directly during the surgery.

Diet for Patients with Bladder Stones

The components of bladder stones are mostly calcium oxalate stones. Dietary precautions include: First, drink more water to increase urine output, promote the expulsion of stones, and prevent further enlargement of the stones. Second, you can drink water with lemon slices to increase the citric acid content in the urine, inhibit the formation of stones, and prevent recurrence. Third, you can consume oranges and other citrus fruits to alkalinize the urine and prevent the stones from growing larger. Fourth, it is recommended to maintain a balanced diet to keep the concentration of various substances in the body stable and in proper proportion, avoiding an increase in the concentration of certain stone-forming substances in the urine.

How to effectively treat bladder stones?

The treatment of bladder stones should be based on the specific size and volume of the stones in the patient. For bladder stones smaller than 1.5 centimeters, extracorporeal shock wave lithotripsy can be used. After the treatment, the patient should drink plenty of water and urinate frequently at home to facilitate the expulsion of the stones. One week later, the patient should return to the hospital for a follow-up ultrasound to observe the condition of the stone expulsion. For bladder stones larger than 1.5 centimeters, surgery is often required.

Clinical manifestations of bladder stones

Generally speaking, a typical clinical manifestation of bladder stones is the sudden interruption of urination. That is, the patient may start to urinate normally, but then suddenly becomes unable to urinate midway through. Urination can resume once the patient changes position. Therefore, this sudden interruption of urination is a classic symptom of bladder stones. Of course, bladder stones can also cause other urinary tract irritation symptoms, such as frequent urination, urgency, pain during urination, and hematuria (blood in urine).

Can bladder stones be crushed?

Whether bladder stones can be treated with lithotripsy depends on their size. If the stone is relatively small, less than 1.5 cm, it can be treated with extracorporeal shock wave lithotripsy. For larger stones, the effectiveness of extracorporeal shock wave lithotripsy is often not very good, and surgical treatment is required, generally for stones larger than 1.5 cm. Currently, the surgical approach involves a minimally invasive procedure using ureteroscopy with holmium laser lithotripsy, and the typical hospital stay is usually less than a week.
