Pulmonary migration following periurethral polytetrafluoroethylene injection for urinary incontinence

J Urol. 1989 Sep;142(3):821-2. doi: 10.1016/s0022-5347(17)38903-6.


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.
