What's wrong with girls wanting to pee after they pee?

After urinating, I still want to urinate. This suggests that there are two possibilities in the later stage of urination: first, there is still no urine in the late stage of urination, such as 450mL urine in the bladder, 350mL urine after urination, and 100mL in the bladder. The treatment of bladder neck sclerosis, drug treatment has tamsulosin, there are some can be operated on, similar to male prostate hyperplasia surgery. Second, urinary tract infection or bladder inflammation, not really do not urinate, is the test shows that has been urinated, but feel not enough urine. In this case can be controlled with drugs, such as M receptor blockers and alpha blockers combined application.
