 Hi, I am Dr. Amrit Rao. I am a urologist and a robotic surgeon working at Manipal Hospital, Bangalore. After examination of the patient, I routinely request an ultrasound scan which will give me the size of the prostate gland, the amount of urine that is left behind in the bladder and also the status of the kidney. I also request blood tests to look at the kidney function and also a special blood test for the prostate gland known as PSA which stands for prostate specific antigen. This will give me information with regards to the risk that a person will have harboring prostate cancer. I also request urine tests such as urine routine and urine microscopy to rule out any infection. The patient will also carry out a flow rate which measures the force with what you pass urine. So these are the investigations that are done for any patient suspicious of having prostate gland enlargement.
