Ae. Lopez et al., TRANSURETHRAL POLYTETRAFLUOROETHYLENE INJECTION IN FEMALE-PATIENTS WITH URINARY CONTINENCE, The Journal of urology, 150(3), 1993, pp. 856-858
We present our results with the use of transurethral injection of poly
tetrafluoroethylene (Teflon) in 128 female patients with moderate to s
evere urinary incontinence from 1964 to 1991. Of the patients 60% had
undergone previous surgical treatment for the incontinence. The etiolo
gies included stress incontinence, neurogenic bladder, congenital anom
alies, trauma and others. More than 73% of the patients improved (54.3
% were totally dry). The failure rate was 27%. Complications were mini
mal. Urinary tract infection and temporary urinary retention occurred
in 7 and 6 patients, respectively. Mean followup was 31 months. This s
tudy demonstrates that transurethral polytetrafluoroethylene injection
is a useful treatment of moderate to severe urinary incontinence in f
emale patients. Polytetrafluoroethylene is particularly useful for pat
ients with failed previous incontinence procedures and poor surgical c
andidates. Failures are more likely in patients with periurethral fibr
osis secondary to a previous urethral operation.
