Can Kidney Stones Be Passed After Shock Wave Treatment? - Urology

Kidney stones can indeed be passed after shock wave lithotripsy (SWL), but the success of this treatment can vary based on several factors, including the size, location, and composition of the stones. Shock wave lithotripsy is a non-invasive procedure that uses sound waves to break kidney stones into smaller pieces, making it easier for them to pass through the urinary tract. However, not all stones are successfully fragmented during the procedure, and some may remain intact or only partially broken.

In your case, it seems that you have undergone SWL for a kidney stone located in your right kidney, and you are still experiencing intermittent pain. This could indicate that the stone has not been completely passed or that there may be residual fragments that are causing discomfort. It is also possible that the pain you are experiencing is related to other factors, such as urinary tract irritation or inflammation.

To determine whether the kidney stone has been completely passed or if there are remaining fragments, follow-up imaging studies, such as ultrasound or CT scans, are often recommended. These tests can help your healthcare provider assess the status of the stone and decide on the next steps for treatment.

Regarding your question about hydration, drinking plenty of fluids is crucial for kidney stone management. It helps dilute the urine, which can reduce the concentration of stone-forming substances and promote the passage of stones. The type of water you drink—whether it is from a water dispenser, purified water, or warm water—does not significantly impact stone passage. The key is to ensure you are adequately hydrated. Aim for at least 2 to 3 liters of water daily, or more if you are physically active or live in a hot climate.

In addition to hydration, some studies suggest that potassium citrate, which can be found in lemon juice, may help in the dissolution of certain types of stones and promote their passage. Drinking lemon juice or taking potassium citrate supplements may be beneficial, but it is essential to discuss this with your healthcare provider before starting any new supplements.

If the stone has not passed and continues to cause pain, your doctor may recommend additional treatments. Options may include:
1. Repeat Shock Wave Lithotripsy: If the stone is still present and is of a size that can be treated with SWL, your doctor may suggest repeating the procedure. However, it is often recommended to wait a certain period (usually around a month) before repeating SWL to allow for healing and to assess the stone's status.

2. Ureteroscopy: If the stone is located in the ureter and is causing significant obstruction or pain, ureteroscopy may be performed. This procedure involves inserting a small scope through the urethra and bladder into the ureter to directly visualize and remove the stone or to use laser lithotripsy to break it up.

3. Percutaneous Nephrolithotomy (PCNL): For larger stones or those that cannot be treated effectively with SWL or ureteroscopy, PCNL may be recommended. This is a minimally invasive surgical procedure that involves making a small incision in the back to remove the stone directly from the kidney.

In conclusion, while kidney stones can be passed after shock wave treatment, the success of the procedure and the subsequent management depend on various factors. It is essential to maintain good hydration, monitor your symptoms, and follow up with your healthcare provider for appropriate imaging and treatment options. If you continue to experience pain or have concerns about your kidney stones, do not hesitate to seek medical advice for further evaluation and management.
