Single-incision slings effectively treat stress urinary incontinence (SUI), but success rates decrease with age. Identifying risk factors like intrinsic sphincter deficiency is crucial for older women.
Area of Science:
- Urogynecology
- Minimally Invasive Surgery
- Geriatric Medicine
Background:
- Stress urinary incontinence (SUI) significantly impacts women's quality of life.
- Single-incision sling (SIS) procedures offer a minimally invasive option for SUI treatment.
- Age-related differences in treatment outcomes for SUI are not fully understood.
Purpose of the Study:
- To evaluate age-related outcomes of single-incision sling (SIS) procedures for SUI.
- To identify predictors of treatment failure in elderly women undergoing SIS procedures.
Main Methods:
- Retrospective multicenter cohort study including 646 women with urodynamically confirmed SUI.
- Patients were stratified into young (≤64 years), elderly (65-74 years), and old (≥75 years) age groups.
- SIS procedures utilized fixed-length or adjustable-length devices via a transvaginal approach.
Main Results:
- Overall objective and subjective cure rates at one year were 89.3% and 87.0%, respectively.
- Cure rates significantly declined with increasing age (objective: 93.7% to 70.6%; subjective: 92.2% to 64.7%, p < 0.001).
- Obesity, asthma, low maximal urethral closure pressure (MUCP), and short functional urethral length (FUL) were risk factors for failure in elderly women, with intrinsic sphincter deficiency (ISD) being the strongest predictor.
Conclusions:
- SIS is an effective treatment for SUI, but its efficacy diminishes with advancing age.
- Risk factors for treatment failure in older women include ISD, low MUCP, and short FUL.
- Optimizing patient selection and counseling based on these risk factors is essential for improving outcomes in elderly SUI patients.
