Significance. The bladder, not normally palpable, may only be palpated when it is grossly enlarged in the setting of urinary retention.

When can bladder be palpated?

Palpation and percussion. It is generally possible to palpate or percuss the bladder above the level of the symphysis pubis if it contains 150 mL or more of urine (Figure 2-3).

What causes palpable bladder?

An enlarged bladder is a relatively common condition. There are many possible causes. One of the most common causes is an obstruction of the urinary system. This can occur in the ureters that connect the kidney to the bladder, or in the urethra which passes urine from the bladder to exit the body.
