hi, there can be several causes of urgency, including infection in urine or prostate
. however, 'prostate growth spurt' is not a cause for the same, it happens in all male teens at puberty
. Prostate growth occurring after 50 yrs of age can cause problems, not at your age. If you are not satisfied with current treatment, consult a urologist
. Also, avoid fizzy drinks/tea/coffee, keep fluid intake to upto 8-10 glasses/day. More fluid intake means more trips to the toilet. Try diverting your mind when your urgency begins, gradually you may be able to hold urine for longer time. good luck.
