Transurethral Polytetrafluoroethylene Injection for Post-Prostatectomy Urinary Incontinence

Transurethral polytetrafluoroethylene (Teflon) injections were performed on 69 men with incontinence following prostatectomy. The etiology of incontinence was transurethral resection of the prostate in 27 patients (group 1), open prostatectomy in 15 (group 2) and radical prostatectomy in 27 (group 3). All patients had been incontinent for more than 1 year and had failed to improve with conservative management. Cure or improvement occurred in 85.1 per cent of the patients in group 1, 79.9 per cent in group 2 and 48.1 per cent in group 3. Reasons for failure included severe bladder instability, severe periurethral fibrosis and leakage of paste. Clinically significant particle migration was not observed.
