Hello and welcome to HCM.
Thank you for your query.
TURP is a good and effective procedure. Recovery period ranges from 7-10 days after surgery. You should be completely fine after this. The reason why I would recommend a one time treatment of your
enlarged prostate is firstly because, the enlargement of prostrate is an age-related development. Thus, there is a chance this might further enlarge with age.
Secondly, due to side-effects of the medications, which not always but can cause
erectile dysfunction, reduced
liver function, and a long list of other effects on other systems.
As you are a diabetic, all that would be required before a physician gives you the fitness approval for surgery would be to have a check on your blood pressure. You are otherwise safe and fit for surgery.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
Best wishes.
