In an exclusive interview with Middle East Health, Dr. Manal Elredy of Sheikh Shakhbout Medical City details the advantages of the Single-Incision Sling – Tension-Free Vaginal Tape (SIS-TVT) procedure, a minimally invasive surgical technique that’s showing promising outcomes in treating stress urinary incontinence. With comparable effectiveness to traditional methods but featuring reduced recovery times and lower complication rates, this innovative approach is emerging as a preferred option for suitable candidates, offering success rates of 70-90% in the short term while requiring just a single incision under local anaesthesia.
Middle East Health: Can you explain what the SIS-TVT (single-incision sling – tension-free vaginal tape) procedure is and how it differs from traditional sling procedures for stress urinary incontinence?
Dr Manal Elredy: The SIS-TVT (Single-Incision Sling – Tension-Free Vaginal Tape) procedure is a minimally invasive surgical technique designed to treat stress urinary incontinence in women. Here’s a breakdown of how it works and how it differs from traditional sling procedures:
SIS-TVT Procedure
Single Incision: As the name suggests, this procedure involves a single incision, usually made in the vaginal wall. This contrasts with traditional sling procedures, which may require multiple incisions.
Tension-Free Approach: The tape used in the SIS-TVT is placed under the mid-urethra and is tension-free, which helps support the urethra without applying unnecessary pressure. This can potentially lead to fewer complications and a faster recovery.
Minimally Invasive: The SIS-TVT is performed with smaller instruments, leading to less tissue trauma and quicker recovery times for patients.
Differences from Traditional Sling Procedures
Incision Size and Number: Traditional sling procedures often involve two incisions (one in the vaginal wall and one in the abdomen), whereas SIS-TVT uses just one incision.
Surgical Technique: Traditional procedures like the mid-urethral sling (e.g., tension-free vaginal tape or TOT) may have variations in how the mesh is anchored, often resulting in a different placement method compared to SIS-TVT.
Recovery and Outcomes: Because SIS-TVT is less invasive, patients typically experience shorter recovery times, less postoperative pain, and a quicker return to normal activities.
Complications: Some studies suggest that SIS-TVT may have lower rates of certain complications (like mesh erosion) compared to traditional sling techniques, although individual outcomes can vary.
Overall, the SIS-TVT procedure aims to provide effective treatment for stress urinary incontinence with fewer risks and a more comfortable recovery process compared to traditional sling methods.
MEH: What specific patient characteristics or factors make someone an ideal candidate for the SIS-TVT procedure?
Dr Manal Elredy: Ideal candidates for the SIS-TVT (Single-Incision Sling – Tension-Free Vaginal Tape) procedure typically exhibit the following characteristics and factors:
Patient Characteristics
Diagnosis of Stress Urinary Incontinence: Patients should have a confirmed diagnosis of stress urinary incontinence, characterized by involuntary leakage of urine during activities that increase abdominal pressure (e.g., coughing, sneezing, exercise).
Moderate to Severe Symptoms: Candidates often have moderate to severe symptoms that significantly impact their quality of life and daily activities.
MEH: What are the advantages of the SIS-TVT procedure compared to other similar procedures?
Dr Manal Elredy: The SIS-TVT (Single-Incision Sling – Tension-Free Vaginal Tape) procedure offers several advantages compared to other surgical options for treating stress urinary incontinence, including traditional sling procedures and other surgical interventions. Here are some key benefits:
