During suprapubic aspiration, a needle is inserted through the skin into the bladder to withdraw a urine sample. Local anesthesia may first be used to numb the area.
This method is often used to obtain a urine sample from a young child or infant to confirm or rule out the possibility of a urinary tract infection. It helps ensure a clean urine sample because urine that is withdrawn directly from the bladder is less likely to be contaminated with bacteria from the skin.
