Summary
The transcorporal artificial urinary sphincter (TC AUS) has higher revision rates but comparable explantation, continence, and quality of life outcomes versus other AUS. TC AUS shows lower infection and erosion risks, making it a viable option for complex cases.
Area of Science:
- Urology
- Prosthetic Surgery
- Medical Device Research
Background:
- Artificial urinary sphincter (AUS) devices are used to manage urinary incontinence.
- Transcorporal (TC) AUS represents a specific surgical approach for AUS implantation.
- Understanding the comparative outcomes of TC AUS is crucial for clinical decision-making.
Purpose of the Study:
- To systematically review and meta-analyze survival and functional outcomes of TC AUS compared to other AUS approaches.
- To evaluate revision rates, explantation, continence, quality of life, infection, and erosion associated with TC AUS.
Main Methods:
- Systematic review and meta-analysis of Medline and Embase databases up to January 2024.
- Inclusion of 20 studies (8 comparative, 12 non-comparative).
- Risk of bias assessment using ROBINS-I and EAU tools.
Main Results:
- TC AUS demonstrated significantly higher revision rates (OR 2.99) but not explantation rates (OR 1.41).
- Continence and quality of life outcomes were comparable between TC AUS and other approaches.
- TC AUS showed significantly lower infection (OR 0.33) and erosion rates (OR 0.35), even in high-risk populations.
Conclusions:
- TC AUS exhibits higher revision rates but comparable explantation and functional outcomes.
- The lower infection and erosion rates suggest TC AUS is a viable option, particularly in complex cases and high-risk populations.
- TC AUS may offer an alternative approach with a potentially improved safety profile regarding infection and erosion.
