What is the optimal length for single-incision tape?

Area of Science:

• Urology
• Gynecology
• Surgical Innovation

Background:

• Urinary incontinence is a common condition affecting many women.
• Midurethral tape procedures are standard treatments for stress urinary incontinence.
• Single-incision midurethral tape (SIMS) offers a less invasive approach.

Purpose of the Study:

• To assess the required length of the adjustable single-incision midurethral tape (SIMS; Ajust) for secure fixation to the obturator membrane.
• To deduce the optimal length of SIMS based on intra-operative measurements.
• To compare the effective tape lengths of SIMS (Ajust) and traditional tension-free vaginal tape obturator (TVT-O).

Main Methods:

• Intra-operative data from a randomized trial comparing Ajust and TVT-O were analyzed.
• The length of the Ajust tape was calculated using a specific formula accounting for components.
• The length of the TVT-O tape was calculated based on snipped portions.
• Correlation between tape length and biometric parameters (height, weight, BMI) was assessed.

Main Results:

• The mean length of the Ajust tape within the body was 11.6 cm (SD 0.9), ranging from 9.6 cm to 14.6 cm.
• The mean length of the TVT-O tape within the body was 20.3 cm (SD 2.1), ranging from 14.8 cm to 24.5 cm.
• Data from 50 women in each group (Ajust and TVT-O) were utilized.

Conclusions:

• Achieving continence with single-incision tape necessitates varied tape lengths.
• Inappropriate SIMS length can lead to treatment failure, attributable to the tape itself, not the surgical technique.
• Understanding optimal SIMS length is vital for successful surgical outcomes in treating stress urinary incontinence.
