My urologist said my prostate was slight enlarged after a sonogram. he ordered a psa, semen culture, and kub x-ray. is this normal? what are they looking for?

See remark: What were your symptoms to have PSA? At your tender age no one expects prostate cancer.Did you have symptoms of frequency,burning,irritation to have the tests. To visit a urologist you must have had urinary complaints, warranting investigation I assume nothing positive was found ! They were LOOKING FOR CAUSE FOR YOUR COMPLAINT....

Here are some ...: Did you have recurrent urinary tract infections (UTI), or just have some recent or long change in how you urinate? Ordering PSA, semen culture, & KUB is to see if your prostate has infection-related inlammation or if you may have urinary stone since all documented UTI in men should always be considered as complicated UTI. So, she/he wants to see what may be the underlying reasons for your symptoms
