Summary
The AMS-800 artificial sphincter is effective for treating urinary incontinence from sphincter incompetence, though complications occur. Post-prostatectomy patients achieve the best outcomes with this device.
Area of Science:
- Urology
- Medical Devices
- Surgical Innovation
Context:
- Urinary incontinence secondary to sphincteric incompetence presents a significant clinical challenge.
- Artificial urinary sphincter implantation is a treatment option for severe cases.
- The AMS-800 device has been utilized for over two decades.
Purpose:
- To evaluate the efficacy and complication rates of the AMS-800 artificial sphincter in patients with sphincteric incompetence.
- To analyze outcomes based on the etiology of incontinence and device placement.
- To compare results across different patient subgroups.
Summary:
- A review of 63 patients with sphincteric incompetence treated with the AMS-800 artificial sphincter was conducted.
- Complications included malfunction, infection, and rejection, with 39 reoperations in 28 patients.
- Successful functional results were achieved in 48 patients, with 15 failures.
Impact:
- The AMS-800 is an effective treatment for urinary incontinence due to sphincteric incompetence, particularly post-prostatectomy.
- Neurogenic incontinence cases exhibit higher complication rates and poorer outcomes.
- Alternative techniques are preferred for female patients due to ease and cost-effectiveness.
