After kidney stones?


Hello Doctor: I discovered I had kidney stones around April or May.
I experienced intermittent hematuria and pain for a long time, and I took medication.
It wasn't until mid-August that I had a CT scan and underwent ESWL (Extracorporeal Shock Wave Lithotripsy).
Two weeks post-surgery, I returned for a follow-up and had an X-ray, which showed a light-colored area at the stone site (3 cm from the lower ureter to the bladder), indicating it had been fragmented.
The doctor said not to worry, as it would eventually pass.
Since the ESWL, I have been drinking at least 1500 ml of water daily, and I no longer experience kidney swelling or hematuria.
However, yesterday I felt a brief twitching sensation in my urethra, and today, after working out, I suddenly had hematuria again, but without pain.
I would like to know if this could be due to the formation of new stones or if the previous fragments are slowly passing.
Do fragments remain in the body for such a long time (almost two months) after being broken up? Since I am currently abroad, it is not convenient to arrange for an examination.
I would like to ask for some maintenance methods.
Thank you!

Hello: Some fragments or powder from kidney stones may take a while to pass, sometimes several months.
If you are under 40 years old, it's advisable to drink plenty of water and schedule a follow-up appointment.
If you are over 40 years old and have hematuria, further evaluation is necessary to rule out other causes.
Aim for light-colored urine as an indicator of adequate hydration.
If you are sweating a lot and your urine is dark, increase your fluid intake.
Regular movement is beneficial for stone passage, while prolonged sitting is not recommended.
Additionally, beverages such as coffee, tea, and cola should be consumed in moderation, with plain water being the primary choice.
There are no significant dietary restrictions, but it is best to avoid excessive salt.

Wishing you good health.

More Info


After undergoing Extracorporeal Shock Wave Lithotripsy (ESWL) for kidney stones, it is common to experience a range of symptoms and concerns regarding recovery and the potential for new stone formation. Based on your description, it seems you have been proactive in managing your hydration and monitoring your symptoms, which is crucial in the post-ESWL recovery process.

Firstly, the presence of blood in your urine (hematuria) after ESWL can occur for several reasons. It is not uncommon to see blood in the urine shortly after the procedure, as the shock waves used to break up the stones can cause some irritation and minor trauma to the urinary tract. The fact that you experienced blood in your urine after exercising could be related to physical activity, which may have caused some movement of the residual stone fragments or irritation in the urinary tract. If the blood is transient and not accompanied by pain, it may not be a cause for immediate concern, but it should be monitored.

Regarding the sensation of "twitching" in the urethra, this could be related to the healing process of the urinary tract following the ESWL procedure. As the fragments of the stone begin to pass, they can cause sensations of discomfort or movement. It is also possible that the fragments may take some time to fully pass, and they can remain in the urinary tract for several weeks or even months after the procedure.
In terms of new stone formation, it is important to understand that kidney stones can recur, especially if the underlying causes are not addressed. Factors such as dehydration, dietary habits, and metabolic issues can contribute to the formation of new stones. Since you are already drinking at least 1500 mL of water daily, you are on the right track. However, increasing your fluid intake to at least 2000 mL per day, if possible, can further help dilute your urine and reduce the risk of new stone formation.

As for your concern about the timing of follow-up imaging, it is generally recommended to have a follow-up appointment and imaging (such as X-ray or ultrasound) about 4-6 weeks after ESWL to assess the status of the stone fragments and ensure they are passing as expected. However, since you are currently abroad and may not have access to immediate medical care, it is essential to monitor your symptoms closely. If you experience significant pain, persistent hematuria, or any signs of infection (such as fever or chills), you should seek medical attention promptly.

In the meantime, here are some additional self-care tips to help manage your recovery:
1. Hydration: Continue to drink plenty of fluids, aiming for at least 2000 mL per day if possible. This will help flush out any remaining stone fragments and reduce the risk of new stones forming.

2. Dietary Adjustments: Depending on the type of stones you had, consider dietary changes. For example, if you had calcium oxalate stones, reducing foods high in oxalates (like spinach, nuts, and chocolate) may be beneficial. Consulting with a dietitian who specializes in kidney stones can provide personalized guidance.

3. Pain Management: If you experience discomfort, over-the-counter pain relievers like ibuprofen or acetaminophen can help. However, consult with a healthcare provider before taking any medication, especially if you have other health conditions.

4. Physical Activity: While moderate exercise is beneficial, avoid high-impact activities that may exacerbate discomfort or cause injury to the urinary tract.

5. Monitoring Symptoms: Keep a log of your symptoms, including any changes in urine color, presence of blood, pain levels, and any other unusual sensations. This information can be valuable for your healthcare provider when you are able to have a follow-up appointment.

In summary, while some symptoms post-ESWL can be concerning, they are often part of the healing process. Continue to stay hydrated, monitor your symptoms, and seek medical attention if necessary. Once you return home, ensure to schedule a follow-up appointment to evaluate your recovery and discuss any further preventive measures to avoid future stone formation.
