HI, The #1 question is--what is the diagnosis? Do you have a UTI, a prostatitis, an enlarged prostate blocking the urethra, or overactive bladder? It is possible for a male with a small prostate to still have bothersome symptoms. It's not so much the size as it is the configuration of the prostate and whether it's causing an obstruction separate from it's size. You need a urodynamic evaluation where pressures are measured in your bladder thru a very small catheter while the bladder is filled with water and during voiding.
If there is no obstruction, an infection in the prostate (prostatitis) could give you these symptoms, and the treatment is a month of antibiotics. If your shhincter doesn't relax, then pelvic floor muscle physical therapy is needed. If your bladder is overactive that can be treated with medications. If there is an obstruction, and your symptoms are bothering you enough, options would include a few deep cuts in your prostate to open it up vrs the standard TURP using cutting or with a laser. The bottom lne is, you need the urodynamic test to sort out for these problems, then consider the appropriate treatment. Good Luck
