Bladder stones are stones formed inside the bladder, including both primary and secondary bladder stones. The typical symptoms of bladder stones are pain and hematuria, often accompanied by interrupted urine flow, which is a distinctive manifestation of bladder stones. Through ultrasound examination of the urinary system, the size, shape, and number of stones inside the bladder can be detected. For the treatment of bladder stones, small stones can typically pass through the urethra on their own, generally if they are less than 0.6 centimeters. Larger bladder stones can be treated with intravesical lithotripsy. Methods of lithotripsy include extracorporeal shock wave lithotripsy and transurethral lithotripsy to break and remove the stones. Additionally, individuals with bladder stones should drink plenty of water, urinate frequently, and avoid spicy and irritating foods.

How big must a bladder stone be to require surgery?

Bladder stones are a common type of urinary system calculus. Generally, stones with a diameter greater than 1.5 centimeters require surgical treatment. Currently, minimally invasive surgery is performed, which is transurethral ureteroscopic holmium laser lithotripsy. This involves inserting a ureteroscope through the urethra into the bladder, locating the bladder stones under direct vision, and using a holmium laser fiber to fragment them, while simultaneously extracting the broken pieces.

Are bladder stones easy to pass?

Patients with bladder stones, if the stones are less than 0.5 cm in size, can promote the natural expulsion of the stones by drinking more water and urinating frequently. If the stones are larger, over 0.5 cm in size, treatment may require extracorporeal shock wave lithotripsy or surgery. For patients undergoing extracorporeal shock wave lithotripsy, generally, if the stones are between 0.5-1.5 cm in size, this treatment can be performed. After the treatment, it is also necessary to drink more water and urinate frequently to facilitate the expulsion of the stones. For larger stones, over 1.5 cm, surgical treatment is required.

Can bladder stones be expelled?

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.

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).

Do bladder stones cause nausea?

Patients with bladder stones will not experience nausea symptoms; a systemic examination is needed to identify the specific cause of the nausea. The main symptoms of bladder stones include frequent urination, urgent urination, and painful urination, and some patients may also experience visible blood in the urine. If the size of the bladder stone is less than 2 centimeters, it can be treated with extracorporeal shock wave lithotripsy. If the stone is larger, over 2 centimeters, minimally invasive surgery is required for treatment.
