I also have it. very upsetting I can't believe this.
I found this scientific article about one compound they are using to cure the bladder epithelial cells, but I have no idea how to get my hands on it. if you know how, please let me know
its called Extracellular signal-regulated kinase, it has to be activated
I can't post the article I read about it because links are not allowed. if you google "Activation of ERK accelerates repair of epithelial cells" you will probably find the research article I read
