Complications of Teflon injection for stress urinary incontinence.

Four significant complications of Teflon injections for stress urinary incontinence are reported in 22 women and eight men. Three of the complications included periurethral abscess, urethral diverticulum, and periurethral Teflon granuloma with urethral wall prolapse occurred in women. These complications needed surgical excision and further surgery for stress incontinence, in two patients the outcome was good. Among the female patients the cure rate for stress incontinence with Teflon injection was only 18% in the 5-year follow-up. One other complication, a Teflon cyst, occurred in a male who had previously undergone radical retropubic prostatectomy. Only two of the eight men (25%) who received Teflon injections had maintained improvement after 1 year.
