Ureteral Stricture: Symptoms, Diagnosis, and Treatment Options - Urology

More Info

---

Ureteral stricture is a condition characterized by the narrowing of the ureter, which can lead to various urinary symptoms and complications. Understanding the symptoms, diagnosis, and treatment options for ureteral stricture is crucial for effective management and improving the quality of life for affected individuals.


Symptoms of Ureteral Stricture
The symptoms of ureteral stricture can vary depending on the severity and location of the stricture. Common symptoms include:
1. Hematuria: The presence of blood in the urine, which can be microscopic (not visible to the naked eye) or gross (visible).

2. Dysuria: Painful urination, often described as a burning sensation.

3. Urinary Frequency and Urgency: Increased need to urinate, often with a sense of urgency.

4. Flank Pain: Pain in the side or back, which may indicate kidney involvement.

5. Hydronephrosis: In severe cases, the stricture can lead to swelling of the kidney due to urine buildup, although in your case, it was noted that there was no hydronephrosis.


Diagnosis of Ureteral Stricture
Diagnosis typically involves a combination of clinical evaluation and imaging studies. Key diagnostic tools include:
1. Urinalysis: To check for blood, infection, or other abnormalities in the urine.

2. Ultrasound: To visualize the kidneys and urinary tract, assessing for hydronephrosis or other structural issues.

3. CT Urogram: A more detailed imaging study that can help identify strictures and their locations.

4. Ureteroscopy: A direct visualization of the ureter using a thin, flexible tube, which can also allow for interventions like dilation of the stricture.


Treatment Options for Ureteral Stricture
The treatment for ureteral stricture depends on several factors, including the severity of the stricture, symptoms, and whether there are complications such as hydronephrosis. Common treatment options include:
1. Observation: If the stricture is mild and not causing significant symptoms or complications, regular monitoring may be sufficient.

2. Ureteral Dilation: This procedure involves widening the narrowed section of the ureter, which can be done during ureteroscopy.

3. Stenting: A ureteral stent may be placed to keep the ureter open and allow urine to flow freely.

4. Surgical Intervention: In cases where dilation or stenting is not effective, surgical options such as ureteral resection and reconstruction may be necessary.


Addressing Your Specific Questions
1. Need for Further Surgery: Since your recent ultrasound indicated no hydronephrosis, and you are experiencing microscopic hematuria, it may not be immediately necessary to undergo another ureteroscopy. However, regular follow-up is essential to monitor your symptoms and any changes in your condition. If symptoms worsen or if you develop hydronephrosis, further intervention may be warranted.

2. Use of Buwecon (0.125mg): Buwecon is an anticholinergic medication often used to treat bladder overactivity and urinary incontinence. However, it is contraindicated in patients with obstructive urinary symptoms. Given your history of ureteral stricture and the potential for urinary obstruction, it would be prudent to consult your physician before taking this medication. They can provide personalized advice based on your current symptoms and overall health status.


Conclusion
Ureteral stricture can lead to significant urinary symptoms and complications if not managed appropriately. Regular follow-up with your healthcare provider is crucial to monitor your condition and determine the best course of action. If you experience worsening symptoms, such as increased pain, changes in urination, or new symptoms, do not hesitate to seek medical attention. Your healthcare provider can guide you through the appropriate diagnostic and treatment pathways tailored to your specific situation.
