Importance

The proper placement of a midurethral sling (MUS) is the key factor for a successful surgical outcome.

Objective

This study aimed to evaluate the relationship of perineal ultrasonographic measures of the tape location with subjective and objective outcomes after MUS surgery at midterm follow-up of women.

Methods

The tape percentile (TP; total urethral length/bladder neck tape distance×100) and urethra tape distance (UTD; the shortest distance from the longitudinal smooth muscle complex of the urethra to the midpoint of the tape) were correlated with midterm surgical success. Patient satisfaction measured with the visual analog scale (VAS) was considered as the primary outcome. The presence of stress urinary incontinence on direct questioning, the Urinary Distress Inventory 6 (UDI-6) scores, findings of the cough stress test, free uroflowmetry, postvoid residual volume, and single-cycle voiding ambulatory urodynamic monitoring (AUM) were the other outcomes.

Results

Seventy-eight women were evaluated at a mean follow-up of 4.4 ±3.3 years. Women who were highly satisfied (VAS ≥ 8) had a significantly higher TP (64.7% vs 50.8%, P < 0.001) and lower UTD (3.6 vs 4.5 mm, P = 0.018). Irritative, stress, and obstructive scores at UDI-6 increased as the tape was located closer to the bladder neck (P < 0.001, P < 0.001 and P = 0.044, respectively), and stress symptoms decreased with a tape closer to the urethra (P < 0.001). Women with detrusor overactivity at AUM were found to have a lower TP (P < 0.001).

Conclusion

The perineal ultrasonographic evaluation of tape location with UTD and TP seems to be well correlated with the women's midterm MUS surgical outcomes.
