PSA, as the name states, is an antigen the body produces, not a hormone or an enzyme. It can be elevated for a number of reasons, including enlarged prostate (BPH - benign prostate hyperplasia), infection, cancer, etc. After an episode of prostatitis a couple of years ago, mine was elevated to 19, when measured, but probably was higher before I saw a doctor. Informative, if you can get the info, is the number of free PSA, the higher the number the more likely it is cancer. But the only way to tell is by biopsy.
I assume you meant that he still wasn’t able to void, so the Foley cathether was put back in.
Last November, after surgery for an avulsed Achilles’ tendon, I had the same problem: not being able to void. I knew I had BPH, but was taking saw palmetto for it. I was catheterized in the hospital, but no Foley was put in. I was still unable to void (I was discharged in that condition), saw my primary physician two days later, who gave me Flowmax and was upset that I wasn’t taking the Flowmax (taking saw palmetto instead - which my urologist said was OK), but that didn’t help and I had to go to the ER, where a Foley was inserted. To make a long story short (or is it too late for that), I had to undergo laser surgery on the prostate and still had to use the Foley for a few days later. I had to wait two weeks for the laser, so I had the Foley in for about three weeks. After it was removed, and I was finally able to void, I had irritation you wouldn’t believe. My penis hurt like hell when I touched it or when I urinated. In addition, I had incontinence when farting or sneezing. Those symptoms slowly abated. I am now symptom-free, but with still a little pain around the prostate when doing abdominal exercises.
But the point is that your father cannot keep the Foley in indefinitely. The doctor said it was an enlarged prostate. That is not necessarily cancer. Most men’s prostates become enlarged after the age of 50 or so. The only way to tell is by the biopsy, and your father simply must have that done. It is a simple procedure, without the use of any anesthesia, and takes only a few minutes. It is, however, quite painful, as 6 needles are inserted through the rectum into the prostate. If he doesn’t have cancer, laser surgery is something that he simply must have, as he cannot, I repeat, keep a Foley in forever. He must have that done and take medicine for the prostate.
