Kidney stone

Manifestations of renal calculi

Patients with kidney stones often suffer from pain when urinating. Blood streaks or small stones can be found in urine. The whole body may have fever, chills and other manifestations, and some may also have colic in the back or lower abdomen, nausea and vomiting.

Treatment of renal calculi

According to the composition and size of the stones, the treatment methods for kidney stones are different.

1. Medication

Patients with stones less than 0.6 cm, no obvious symptoms and no renal function damage can choose drug therapy. Drug therapy mainly includes drinking more water and increasing urine volume. Control of infection; Promote ureteral peristalsis and accelerate stone discharge.

2. Extracorporeal shock wave lithotripsy

Extracorporeal shock wave lithotripsy is mainly suitable for kidney stones less than 2.5 cm. When the stone volume is too large, multiple lithotripsy is required, the stone removal time is long, and the stone is easy to remain.

3. Percutaneous nephrolithotomy

Percutaneous nephrolithotripsy is currently the most widely used minimally invasive surgical method for the treatment of kidney stones. This method is to make a small hole with a diameter of about 0.6 cm in the waist of the patient, establish a channel between the skin and the kidney, then extend an endoscope with the thickness of chopsticks into the stone part of the kidney, and finally smash and take out the stone.
