my dad is unable to urinate out from his penis since four days .what is the best drug for such infection? what may be the problem?

Go to the doctor! I would assume that he is able to urinate another way, correct? 4 days is a pretty long time to hold it!

lol

urinary retention due to enlarged prostate is the most likely reason . urinary tract infection is less likely.
