How is a Bladder Diverticulum Diagnosed?

Bladder diverticula can be found with an x-ray test of the bladder. The test is done by filling the bladder with a dye that shows up well in x-rays (called a "contrast") and taking pictures. Your health care provider may also look into your bladder with a cystoscope, a long, thin telescope with a light at the end. This is to check for bladder tumors in the diverticulum. A pressure test called "urodynamics" may also be done to see how well the bladder works and check for blocks. Your health care provider may use ultrasound, which takes pictures of your organs by bouncing sound waves off them, to see how any blocks affect your kidneys.
