Meatitis

Inflammation of the urethral meatus, characterized by erythema, tenderness, and sometimes erosions or crusting at the external urethral opening, which may cause dysuria and irritative voiding symptoms. Possible causes are chemical irritation (ammonia in diapers, soap), mechanical friction (diaper, bicycling, catheterization), and infection (gonorrhea, chlamydia, mycoplasma, strep, candida).
