This topic is about a 69-year-old woman who is experiencing severe vaginal irritation and burning after having a ureteric stent placed to bypass scar tissue. Despite various treatments and consultations, she continues to suffer from discomfort that affects her daily life. Here are some insights and advice that might help:

1. If it's medically safe, consider temporarily removing the stent to see if the symptoms improve. This could help determine if the stent is causing the irritation. During this time, alternative drainage methods, like an external pad, might be used.

2. Check how long the current stent has been in place. Sometimes, leaving a stent in for too long can increase irritation, so it's important to monitor its duration.

3. Make sure that any swab samples taken are thoroughly cultured and speciated. This ensures that if there is an infection, the prescribed antibiotics will effectively target the specific organism.

4. You might want to try a tea tree oil vaginal suppository. It has antimicrobial and soothing properties, but be cautious if the mucosa is broken, as it can cause a burning sensation.

5. Consider the possibility of an allergic reaction to the material of the stent. Discuss with your urologist whether there are alternative stent materials that might be less irritating.

These steps might provide some relief or at least help identify the root cause of the discomfort.
