What Is a Bladder Scan?
A bladder scan is a quick, noninvasive ultrasound test that measures how much urine is in the bladder. Healthcare providers use it to determine whether the bladder is emptying properly or retaining urine after urination. Unlike catheterization, a bladder scan does not require inserting any instruments into the body.
The procedure is painless, takes only a few minutes, and provides immediate results.
Why a Bladder Scan Matters
A bladder scan helps identify urinary retention, evaluate bladder function, and guide treatment decisions while reducing the need for unnecessary catheterization and lowering the risk of urinary tract infections.
Why Your Healthcare Provider May Order a Bladder Scan
- Difficulty emptying the bladder
- Urinary retention
- Frequent urinary tract infections
- Monitoring after surgery
- Evaluation of urinary incontinence
- Neurological disorders affecting bladder function
How Is a Bladder Scan Performed?
A small handheld ultrasound device is placed on the lower abdomen after applying a small amount of gel. The device uses sound waves to estimate the amount of urine in the bladder, and results are available immediately.

- Noninvasive
- Painless
- Quick results
