I just completed the six week of Jelmyto treatments for low grade urethane papillary urothelial carcinoma. I did not have any major side effects, after the 5 and 6 treatments I developed a very itchy rash mostly on my hands and feet, it was uncomfortable for 48 hrs and cleared completely after 5 days. Waiting to see the urologist in two weeks to find what is next. Not sure if the nephroureteral tube will be removed.
