My husband had RARP in 2014, no side effects, all good until 2023 when PSA began to rise. Did 33 salvage radiation treatments last year. 6 month retest PSA undetectable, this month came in at .11. Recheck and new scans end of January. His biggest challenge during the radiation was “empty bowel, full bladder”, as someone has mentioned. When we began eating dinner earlier and eliminated some foods (such as salad, sweet potatoes) he did fine. His appointments were at 9:30 am so he also got up around 6 to get all the necessary matters done. He has been lucky with no incontinence or bowel issues. Best of luck to you!
