DRE
Another diagnostic test that your doctor might use is the DRE or digital rectal examination. It is basically a physical check of the prostate. You need to lie on your side or lean over the table while holding the knees near to the chest. After that, the physician will insert his or her finger into your rectum to examine the prostate gland. If this organ is enlarged, it might obstruct your bladder and cause a kidney infection. A DRE is a safe procedure that does not require anesthesia. [5]
