Bladder percussion

Bladder percussion is an examination method used to determine the extent of bladder inflation. Bladder examination is an auxiliary examination method to check whether the abdominal bladder is normal. When the bladder is empty, because there is an intestine above the pubic bone, the percussion is drum sound, and the outline of the bladder cannot be found. When the bladder is filled with urine, the percussion above the pubic bone presents a circular dullness. Through this examination, you can determine the lesion site and the corresponding symptoms.
