Suggest Remedy For Frequent And Weak Stream Of Urination

Hi. I ve been on tamasulin and finasteride for six months with no improvement other than a reducing my PSA. My urologist is going to do a bladder scan in a couple of weeks. Not really looking forward to that. I m a 58 year old male and I have had urination problems for what seems like forever. Week stream and frequent urination are at the top of the list. I m up every 3 - 4 times at night and during the day am urinating as often as twice an hour. What exactly will he be looking for?
