For me, issues started in my early 50s in the form of dribbling after peeing. It was hard to keep my pants dry so I used pads. The urologist ascribed it to BPH and a stricture in my urethra.
Then, at age 60, with rising PSA and a family history of prostate cancer I was biopsied and diagnosed with prostate cancer. The tumors were big enough that I had an unilateral nerve sparing radical prostatectomy (nerves were spared only on one side). Nerve damage and the re-arrangement of the urinary tract with the prostatectomy left me incontinent. Currently, I am 64 so this has gradually become my new normal. Often I can't tell that my bladder is full and if it is full, it will empty when I stand up. Also, I have stress incontinence (pee when I sneeze, cough, stand up, exercise, etc.).
