What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores two different surgeries to address stress urinary incontinence, a condition where urine leaks during activities like coughing or exercising. The researchers aim to determine the frequency of pelvic pain six months post-surgery and the number of people cured of incontinence five years later. They also examine other factors, such as pain medication use and mental and sexual health after surgery. This trial suits women over 60 who have tried other treatments for urinary incontinence without success and are ready for surgery. As an unphased trial, it offers a unique opportunity to contribute to research that may enhance surgical outcomes for others.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that both autologous fascia slings and tension-free vaginal tape (TVT) are generally safe treatments for stress urinary incontinence. Studies indicate a moderate complication rate of 20% for the autologous fascia sling, but most side effects are manageable and don't cause long-term issues. Temporary problems like difficulty urinating can occur but usually resolve on their own.

Long-term studies confirm the high safety and effectiveness of tension-free vaginal tape. About 80% of patients experience significant improvement in their symptoms. The chance of needing additional surgery is low, ranging from 0% to 19% over five years. Both treatments have strong safety records, making them good options for managing stress urinary incontinence.12345

Why are researchers excited about this trial?

Researchers are excited about these treatments for urinary incontinence because they offer different surgical approaches to provide support to the urethra. The autologous fascia sling uses tissue from the patient's own body, which may reduce the risk of rejection and complications associated with synthetic materials. On the other hand, tension-free vaginal tape, a synthetic option, is known for being less invasive and typically allows for a quicker recovery time. These two options provide varied benefits, allowing for personalized treatment based on a patient's specific needs and circumstances.

What evidence suggests that this trial's treatments could be effective for urinary incontinence?

This trial will compare the effectiveness of two treatments for stress urinary incontinence: the autologous fascia sling (AFS) and tension-free vaginal tape (TVT). Research has shown that both AFS and TVT effectively treat this condition. Participants in the AFS arm may achieve complete bladder control in about 78.3% of cases, indicating significant symptom management. Meanwhile, those in the TVT arm may experience strong long-term outcomes, with up to 76.3% of patients showing lasting improvements even after 20–25 years. Both treatments have similar success rates, but AFS usually takes longer to perform. Overall, strong evidence supports both options in reducing symptoms of stress urinary incontinence.12346

Are You a Good Fit for This Trial?

This trial is for women over 60 who have stress urinary incontinence, have finished having children, and can attend clinic visits for up to five years. They should be able to undergo either tension-free vaginal tape or autologous fascia sling surgery after not improving with non-surgical treatments.

What Are the Treatments Tested in This Trial?

Interventions

  • Autologous Fascia Sling
  • Tension-free Vaginal Tape

Trial Overview

The study compares two surgeries: a synthetic mesh sling known as tension-free vaginal tape (TVT) and an autologous fascia sling (AFS), made from the patient's own tissue. It looks at pain six months later and if incontinence is cured after five years, along with opioid use and mental health outcomes.
