ANSWER: Howard

Frequent urination does not damage the kidneys or bladder, but the underlying prostate problem can. This does typically take time; usually months. An infection should be easy to identify from a urine sample.  Proscar and climax are the standard treatments. If they are not worming, the Flomax can be increased to 2 daily. If this also does not work, then prostate surgery may be needed. If.this problem is not adequately created, it can eventually damage the kidneys.

QUESTION: if there is no infection but juse frequent urination due to enlarged prostate whould kidneys get badly damaged from frequent urination or more likely infection. have been taking proc-scar and it must have shrank my prostate or else I would not urinate as much.if kidneys are damaged you urinate less

As stated earlier, the kidneys are not damaged by frequent urination by itself but by the underlying cause.  If there is blockage from the prostate, then the bladder has to squeeze harder. This is what can cause kidney damage.

It is not necessarily true that kidney damage causes you to urinate less.  Even people with significant levels of renal failure can still make urine but the urine is much like water and may not contain the same level of waste products that normal urine would have.  

Proscar can shrink the prostate, but it typically takes at least 6 months to work.
