Are there any side effects after undergoing extracorporeal shock wave lithotripsy (ESWL)?


After my father underwent extracorporeal shock wave lithotripsy, he now experiences tremors when using a spoon to drink soup (he did not have this issue before the procedure).
Is this a side effect of the procedure, or could it be a symptom of another condition? Additionally, he has persistent lower back pain.
How long might these symptoms last?

Hello: The common side effects of extracorporeal shock wave lithotripsy include hematuria, back pain, or gastrointestinal symptoms.
I have not heard of any cases involving tremors.
It is advisable for the patient to undergo a detailed examination by a neurologist.
Thank you!

More Info


After undergoing Extracorporeal Shock Wave Lithotripsy (ESWL), it is not uncommon for patients to experience a variety of side effects, including tremors and back pain. These symptoms can be concerning, especially if they are new and have not been experienced before the procedure.
Firstly, tremors can occur for several reasons post-ESWL. One possibility is that the procedure itself can cause temporary muscle spasms or tension in the body, particularly in the back and abdominal areas, which may lead to involuntary shaking or tremors when performing fine motor tasks, such as holding a spoon. Additionally, the stress of the procedure and the body's response to pain can also contribute to tremors. If your father is experiencing significant anxiety or discomfort, this could exacerbate the tremors as well.

Back pain is another common side effect following ESWL. The shock waves used during the procedure can cause some degree of trauma to the surrounding tissues, leading to inflammation and discomfort. This pain may be felt in the lower back, where the kidneys are located, or in other areas due to muscle tension or guarding as the body tries to protect itself from pain. It is important to note that this pain is usually temporary and should gradually improve over time.

In terms of duration, the side effects of ESWL, including tremors and back pain, can vary from person to person. Typically, these symptoms may last from a few days to a couple of weeks as the body heals from the procedure. However, if the symptoms persist beyond this timeframe or worsen, it is crucial to consult with a healthcare provider. They can assess whether these symptoms are indeed related to the ESWL or if there may be other underlying issues that need to be addressed.

It is also worth considering that other factors, such as dehydration, electrolyte imbalances, or even medication side effects, could contribute to tremors and back pain. If your father is taking any medications for pain management or other conditions, it would be wise to review these with his doctor to rule out any potential interactions or side effects.

In summary, while tremors and back pain can be common after ESWL, it is essential to monitor these symptoms closely. If they persist or are accompanied by other concerning signs, such as severe pain, changes in urinary habits, or fever, seeking medical attention is advisable. A healthcare professional can provide a thorough evaluation and determine the best course of action to alleviate these symptoms and ensure a smooth recovery.

Dr. Tu Xiuhong reply Urology
Hello: 1. The tingling sensation in the right calf should consider issues related to the sciatic nerve and whether it is associated with shock wave lithotripsy. 2. The lower back pain must be evaluated at a hospital to determine if there is a recurrence of kidney stones.
