Ureteral issues


Hello doctor, last Friday I suddenly experienced severe pain in my lower left abdomen.
I went to the emergency room and was diagnosed with kidney stones.
After that, I consulted a doctor who performed a ureteroscopy and mentioned that my ureter is too narrow, and even the smallest instruments could not be inserted.
Then I underwent extracorporeal shock wave lithotripsy, but the doctor said the X-ray was unclear and was hesitant to proceed with the treatment.
Now, I feel like my left kidney is constantly swollen, and drinking too much water causes pain.
What should I do now?

Regarding the treatment options for ureteral stones: 1.
For small stones (<0.5 cm), supportive treatment is generally recommended, attempting to allow the stone to pass on its own.
2.
For larger stones (>0.5 cm) or in cases of intolerable renal colic or associated infections, the current treatment methods primarily include extracorporeal shock wave lithotripsy (ESWL) or ureteroscopy with stone removal.
3.
If neither of these methods is effective, traditional ureterotomy for stone extraction may be considered.

It sounds like you are experiencing a challenging situation with your ureteral issues and kidney stones. Based on your description, you have been diagnosed with kidney stones and have encountered complications related to a narrowed ureter, which can significantly affect your urinary function and overall kidney health.
When it comes to managing kidney stones, especially in the context of a narrowed ureter, there are several important considerations. First, it's crucial to understand that kidney stones can vary in size, composition, and location, which can influence the treatment options available. In your case, the fact that your ureter is too narrow for even the smallest instruments to pass through complicates the situation. This narrowing, known as ureteral stricture, can lead to obstruction, causing hydronephrosis (swelling of the kidney due to urine buildup) and potentially damaging kidney function if not addressed.

Given that you are experiencing persistent pain and swelling in your left kidney, it is essential to take proactive steps. Here are some recommendations based on medical knowledge and practices:
1. Follow-Up with a Urologist: Since you have already seen a urologist, it is crucial to maintain regular follow-ups. They can monitor your kidney function and the status of the stones. If your symptoms persist or worsen, further imaging studies, such as a CT scan, may be warranted to assess the situation more accurately.

2. Consider Ureteral Stenting: If your ureter is too narrow for standard procedures, your urologist may recommend placing a ureteral stent. This is a small tube that can help keep the ureter open, allowing urine to flow from the kidney to the bladder. It can relieve pressure and pain associated with hydronephrosis.

3. Extracorporeal Shock Wave Lithotripsy (ESWL): If the stones are not visible on X-ray due to their composition (e.g., they may be less dense or composed of materials that do not show up well), your doctor may consider alternative imaging techniques or methods to break the stones. ESWL is a non-invasive procedure that uses shock waves to break stones into smaller pieces that can be passed more easily.

4. Hydration and Pain Management: While you are experiencing pain when drinking more fluids, staying hydrated is still essential. It can help flush out smaller stones and prevent new ones from forming. Discuss with your doctor about pain management strategies that can help you tolerate increased fluid intake.

5. Surgical Options: If non-invasive methods fail, or if the stones are causing significant obstruction and pain, surgical intervention may be necessary. This could involve ureteroscopy, where a small camera is inserted into the ureter to remove or break up stones directly.

6. Monitoring Kidney Function: Regular blood tests to monitor kidney function (such as serum creatinine levels) are important, especially if you are experiencing hydronephrosis. This will help your healthcare provider assess any potential damage to your kidneys.

7. Lifestyle Modifications: Depending on the type of stones you have, dietary changes may be beneficial. For example, reducing salt intake, limiting animal protein, and increasing fruits and vegetables can help manage certain types of stones.

In summary, managing ureteral issues and kidney stones requires a comprehensive approach involving regular medical follow-up, potential interventions like stenting or surgery, and lifestyle modifications. It is essential to communicate openly with your healthcare provider about your symptoms and concerns, as they can tailor the treatment plan to your specific needs. Your health and comfort are paramount, and addressing these issues promptly can help prevent further complications.
