Can using unclean paper to wipe after urinating cause infection?

In general, wiping after urination with unclean paper may not lead to infection, but it could potentially cause infection depending on the specific circumstances. Details are as follows:

1. No infection

If unclean paper is used only occasionally for wiping after urination, infection may not occur. Urine has certain antibacterial properties, and this self-cleaning ability can help reduce the risk of infection. Additionally, the body's immune system helps defend against invasion by bacteria and other pathogens. If the immune system is functioning normally and the individual is healthy, it can typically resist potential infections.

2. Infection possible

If unclean paper is frequently used for wiping after urination, infection may occur. Unclean paper may carry bacteria or other pathogens, which could enter the urethra upon contact with the urethral opening or skin, then travel upward into the bladder and other urinary tract organs, leading to a urinary tract infection.

It is recommended to avoid using unclean paper for wiping after urination to prevent health problems. If discomfort occurs, seek medical attention promptly and follow standardized treatment under a doctor's guidance, which can help promote recovery.
