“Is prostatectomy a high-risk surgery?”

Not atall. It’s actually very low risk in terms of serious life threatening events. However it can cause incontinence, pain , infection and erectile issues in some cases. Many newer forms of prostate surgeries are now available- using laser - which even very low complication risk. If you really need a prostatectomy- as in for prostate CA- you should go for it.
Thx

Yes, it is.
