Can povidone-iodine be applied to the urethral opening?

Generally, povidone-iodine can be used to clean the urethral meatus. However, its use should follow medical advice. The detailed explanation is as follows:

The urethral meatus is the opening of the urinary system to the outside and is susceptible to invasion by various bacteria, viruses, and other pathogens. Povidone-iodine can effectively kill common pathogens such as Escherichia coli, Staphylococcus aureus, and Candida albicans. Wiping the urethral meatus with povidone-iodine can significantly reduce the number of bacteria around the area and lower the risk of urinary tract infections, such as urethritis and cystitis.

Povidone-iodine is well tolerated by human tissues and causes minimal irritation to the mucous membranes of the urethral meatus. Because the mucous membrane in this area is delicate, a mild disinfectant is required for cleaning and disinfection. While effectively disinfecting, povidone-iodine does not cause adverse reactions such as pain, redness, swelling, or burns to the mucous membrane, nor does it damage the integrity or normal physiological function of the mucous membrane, thereby minimizing adverse effects on the body.

When wiping, handle gently. Use a clean cotton swab dipped in an appropriate amount of povidone-iodine and wipe in a spiral motion from the center of the urethral meatus outward, avoiding excessive force that may damage the mucous membrane.
