Kidney Stones: Symptoms, Treatments, and Urine Color Changes - Urology

Understanding kidney stones is crucial for managing symptoms, treatments, and the implications of urine color changes. Kidney stones, or nephrolithiasis, can cause a variety of symptoms, including hematuria (blood in urine), pain during urination, and changes in urine color. These stones can vary in size and composition, which influences the treatment approach.

In your case, the presence of blood in your urine and subsequent imaging studies indicating a blockage in the left kidney suggest that you may have a kidney stone lodged in the ureter. The fact that you experienced swelling in the kidney (hydronephrosis) indicates that the stone is likely obstructing the flow of urine, which can lead to increased pressure and potential damage to the kidney if not addressed promptly.

The use of medications like "優暢粒劑" (which I assume is a formulation aimed at dissolving or aiding in the passage of stones) can sometimes help in managing smaller stones, particularly those made of uric acid. However, it’s important to note that the effectiveness of such medications can vary based on the stone's composition and size. The color changes in your urine—dark pink in the afternoon and normal later—could be attributed to several factors, including the concentration of urine, hydration levels, or even the medication itself. It’s unlikely that significant stone dissolution would occur within such a short time frame, but movement of the stone could lead to temporary changes in urine color.

If the stone remains lodged in the ureter, surgical intervention may be necessary. Options include:
1. Extracorporeal Shock Wave Lithotripsy (ESWL): This non-invasive procedure uses shock waves to break the stone into smaller pieces that can be passed more easily. It is typically effective for stones that are not too large or too hard.

2. Ureteroscopy: This is a minimally invasive procedure where a small scope is inserted through the urethra and bladder into the ureter to directly visualize and remove the stone. This method is often used for stones that are obstructing the ureter and causing significant symptoms.

3. Percutaneous Nephrolithotomy (PCNL): For larger stones or those that cannot be treated with ESWL or ureteroscopy, this procedure involves making a small incision in the back to remove the stone directly.

Given that you have been experiencing symptoms for nearly two months, it is advisable to discuss with your healthcare provider the possibility of undergoing a ureteroscopy or repeating the ESWL, especially if you continue to experience discomfort or if imaging suggests that the stone has not passed. Delaying treatment could lead to further complications, including kidney damage.

In summary, while the medication may assist in managing your condition, close monitoring and timely intervention are essential to prevent potential complications. Make sure to maintain adequate hydration, as this can help facilitate the passage of stones and reduce the risk of further complications. Always consult with your healthcare provider for personalized advice and treatment options based on your specific situation.
