Hi, whether or not you should get Surgery would depend upon the problems you are facing. If you face crippling frequency or dribbling or bleeding or recurrent infections then you should go in for Surgery. Otherwise, you can continue medicines. Secondly, one concern is that 105cc is quite large and you should discuss with your Urologist about the effectiveness of Surgery. Also, you should get your PSA levels done if they have not been already done. It is a blood test and should be done before medicines or surgery. Take care, Dr Rishi, New Delhi, India.
