title: Pulmonary migration following periurethral polytetrafluoroethylene injection for urinary incontinence.
abstract: We report a case of clinically significant migration of polytetrafluoroethylene (Teflon) paste particles to the lungs after periurethral injection. These particles were identified by standard and polarized light microscopy. Since the long-term effects in humans are not sufficiently known, we strongly warn against the use of polytetrafluoroethylene paste in children or young adults with a normal life expectancy.
