Why Is This Test Done?

Your healthcare provider may recommend this test if you have symptoms like frequent urination, pain during urination, or unexplained bladder issues. It can also be part of evaluating bladder cancer screening or monitoring conditions like interstitial cystitis.

What to Expect Before the Test

You may need to follow specific instructions, such as fasting or avoiding certain medications. A bladder catheter might be inserted to collect urine for analysis while measuring wall thickness.

During the Procedure

The test involves inserting a thin, lighted tube (cystoscope) into your bladder. Ultrasound waves are used to measure the bladder wall thickness. This is generally painless but may cause mild discomfort.

After the Procedure

You may experience mild discomfort or bleeding for a few days. Avoid strenuous activities and follow any post-procedure care instructions provided by your healthcare team.
