Is extracorporeal ureteral lithotripsy dangerous?

After suffering from ureteral stones, there are many treatment methods. If these are relatively small, certain medications can be used to promote the excretion of stones. However, if the stones are relatively large and cannot be excreted normally, extracorporeal lithotripsy can be used for treatment. Generally speaking, this is also a relatively safe treatment method, which does not cause much harm to patients and has a relatively good treatment effect.

The indications and treatment range of the extracorporeal shock wave lithotripsy are as follows: (1) For various kidney stones and ureteral stones less than 1.2 cm, the extracorporeal shock wave lithotripsy should be the first choice for stone removal treatment; because there is no renal damage, the stone removal is thorough, safe and painless, and there is no secondary damage of impact lithotripsy; if the stone diameter is greater than 1.2 cm, the extracorporeal impact lithotripsy can be used first to crush the stone, and then the extracorporeal shock wave lithotripsy can be used for thorough stone removal treatment; to achieve complementary advantages. (2) This device is particularly suitable for acute ureteral stones and the hydronephrosis, renal pelvic dilatation, hydroureter, ureteral dilatation, renal colic, etc. caused by it; it can quickly remove ureteral stones, immediately relieve pain, and quickly relieve the above symptoms; it is currently the preferred treatment for ureteral stones. (3) For patients with multiple kidney stones and ipsilateral ureteral stones, the ureteral stones should be removed first, and then the multiple kidney stones should be removed to prevent the formation of ureteral "stone streets".

Contraindications: Theoretically, except for uncorrectable bleeding diseases and lumen obstruction distal to the stone, which are absolute contraindications for extracorporeal lithotripsy, other conditions can be controlled within the scope of extracorporeal shock wave lithotripsy. However, during clinical treatment, the following situations require special treatment. 1. Pregnant women with stones are generally not suitable for lithotripsy, especially those with lower ureteral stones. This is to avoid the adverse effects of shock waves and radiation on the fetus. Lithotripsy can be performed after delivery. For mid- and upper-ureteral stones that cause unbearable pain, ESWL treatment can be performed under strict control. There are many research reports on ESWL treatment of pregnant women at home and abroad, but no effect of ESWL treatment on the baby has been found. 2. Patients with diabetes mellitus are not suitable for lithotripsy if their condition is not under control, so as to avoid uncontrollable infection after lithotripsy. 3. Patients with severe or acute infection should consider carefully before lithotripsy. ESWL may aggravate the severity of infection and cause serious symptoms such as bacteremia and toxemia. 4. High-risk patients and patients with poor single or multiple organ function, such as patients with heart failure, renal insufficiency, or solitary kidney, can undergo EWSL treatment in an emergency under the control of the medical conditions at the time. In case of complications, they must be treated in a timely manner. 5. Obese patients may not be able to undergo lithotripsy due to positioning difficulties.
