Hello @nosurgery
I can understand your concern about having surgery or not, since you have just the one kidney. I would like you to post the question you just asked to another discussion group about diverticulosis. Here is the link, https://connect.mayoclinic.org/discussion/diverticulosis/?orderby=DESC#chv4-comment-stream-header
This discussion group is larger and has more recent posts. There are a number of Members in that discussion group who discuss both surgical and non-surgical methods for dealing with diverticulitis. While I have personally had a number of episodes of diverticulitis I have never had any perforations, so I've not had surgery. Just meds and dietary changes.
Since you have the complication of one kidney have you considered getting another opinion at a multi-disciplinary medical center, like Mayo or a university medical school? (Mayo has clinics in Minnesota, Florida and Arizona). They might be a good place for you to visit.
In the meantime, please look at the link I provided above and feel free to post your question there or if you prefer you can "Reply" to any of the posts there or ask any questions of the people who have posted.
Will you let me know how you are doing with your decision making process?
1 opinion - have surgery, 2ond opinion- have another attack then surgery. Try to manage medically. This is ruining my life. I don't want to risk infection and access or further perforation. I'm so confused because doc who said wait has the most experience!?
I don't want to doctor shop...
