Cystoscopy lets the doctor look directly at the prostate and bladder. In cystoscopy, a small tube is inserted into the penis, through the urethra, and into the bladder. Some men may have discomfort during and after the test. An x-ray called a urogram lets the doctor see blockage in the urinary tract. A dye injected into a vein makes the urine show up on the x-ray.
Some men are allergic to the dye.
Ultrasound lets the doctor see the prostate , kidneys, and bladder without a catheter or x-rays. The echoes result in pictures of the prostate , kidneys, or bladder on a TV screen. This test is not harmful or painful. A special probe put in the rectum can give a better view of the prostate when the doctor wants to check for prostate cancer.
