Transurethral polytetrafluoroethylene injection for post-prostatectomy urinary incontinence
The Journal of Urology
|September 1, 1984
Summary
Transurethral polytetrafluoroethylene (Teflon) injections effectively treated post-prostatectomy incontinence in most men. Success rates varied by prostatectomy type, with significant improvement observed in over 79% of patients.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Urologic Oncology
Background:
- Post-prostatectomy incontinence affects a significant number of men.
- Conservative management often fails for long-term incontinence.
- Transurethral injection of bulking agents is a treatment option.
Purpose of the Study:
- To evaluate the efficacy of transurethral polytetrafluoroethylene (Teflon) injections for post-prostatectomy incontinence.
- To compare outcomes based on the type of prostatectomy performed.
Main Methods:
- 69 men with incontinence post-prostatectomy received transurethral Teflon injections.
- Patients were categorized into three groups based on prostatectomy type: transurethral resection, open prostatectomy, and radical prostatectomy.
- Incontinence duration exceeded 1 year, and conservative treatments had failed.
Main Results:
- Overall cure or improvement was achieved in 85.1% (group 1), 79.9% (group 2), and 48.1% (group 3) of patients.
- Failure reasons included severe bladder instability, periurethral fibrosis, and paste leakage.
- No clinically significant particle migration was observed.
Conclusions:
- Transurethral Teflon injections offer a viable treatment for post-prostatectomy incontinence, particularly after transurethral or open prostatectomy.
- Patient selection is crucial, considering factors like bladder instability and fibrosis.
- Teflon injections demonstrate a favorable safety profile regarding particle migration.
