Cotton swab test

The cotton swab test is a supplementary test method used to check whether urination is normal. The purpose of the cotton swab test is to determine whether the anatomical relationship of the bladder is normal by measuring the angle of the urethra. After the urethral bladder angle disappears and the abdominal pressure increases, the urethral sphincter is stretched and opened by the bladder wall, resulting in urinary incontinence. It is an auxiliary examination method to check whether the urination function is normal.
