When should you have a bladder scan?
A bladder scan should be considered for use with patients exhibiting acute or chronic urinary dysfunction.

Can ultrasound detect bladder problems?
Ultrasound. Ultrasound uses sound waves to create pictures of internal organs. It can be useful in determining the size of a bladder cancer and whether it has spread beyond the bladder to nearby organs or tissues. It can also be used to look at the kidneys.
