Doing dilation can speed up the recovery process from severe vaginal atrophy.
However, dilation exercise is physically like a sexual intercourse. You will need to pee immediately after each exercise to prevent UTI. Urination can flush out any bacteria that entered into the bladder during the dilation exercise. Otherwise, UTI may occur.
Please stop doing the dilation exercise until the UTI is completely recovered.
When you restart using the dilators, please start with the smaller size first. It is important to move up the sizes gradually, and one size at a time. You may need to allow 2-3 weeks or longer time for each sized dilator.
It is understandable that you wish to move up the sizes quickly to get a more rapid recovery. However, recovery of vaginal atrophy is a slow process. Moving up the dilator sizes too quickly or skipping sizes can cause stretching injuries. Please do not skip the sizes and try the largest dilator first. Please be patient and doing the exercise with a stepwise increment. Reversal vaginal atrophy takes time.
About UTI, if your UTI is acute and the pain is unbearable, you may need to see a doctor to get some prescription drugs to stop the infection and pain.
However, if your UTI is chronic and the pain is bearable, you can control the UTI by drinking a lot of water and taking D-Mannose: https://www.neueve.com/products/corsaria

Tips about using dilators:
1) Avoid overstretching. It is understandable that one may wish to move up the sizes quickly to get a more rapid recovery. However, this can be counterproductive. The recovery of vaginal atrophy is a slow process. Moving up the dilator sizes too quickly or skipping sizes can cause overstretching, which in turn can tear the atrophied tissue to cause injuries. Please do not skip the sizes and try the largest dilator first. Please be patient and do the exercise with a stepwise increment to avoid possible injuries due to overstretching. Please give one size dilator at least 3-4 weeks to allow tissue to catch up the growth before moving up to the next size.
2) Preventing UTI. Physically, dilation exercise is like sexual intercourse. The penetration movement can mobilize bacteria normally on the skin into the bladder to cause UTI. You will need to pee immediately after each exercise to prevent UTI. Urination can flush out any bacteria that entered the bladder during the dilation exercise. Therefore, drinking a lot of water before exercise helps build up the urinating flushing pressure and prevent UTI.
