Abstract

Objective

The aim of this study was to evaluate patient-reported outcomes after sling release for obstructive voiding after sling operation for female stress urinary incontinence.

Methods

All female patients who had sling release for obstructive voiding at Mayo Clinic in Rochester, Minnesota, from January 1, 2000, through October 31, 2008, were identified and mailed a survey including validated questions for voiding symptoms. A composite outcome for surgical success was chosen in which participants reported global improvement (at least “much better”) and complete satisfaction on a 7-point Likert scale. Logistic regression analysis was used to identify clinical and surgical predictors of this outcome.

Results

In total, 101 women were identified, of which 98 were alive at the time of mailing, and 55 women (56.1%) responded to the survey. Surgery before sling release was a synthetic midurethal sling in 62 patients and biologic sling in 39 patients. Clinical characteristics among mailing responders and nonresponders were similar aside from time from revision surgery to survey (median, 38.8 vs 54.6 months; P = 0.05). Overall, 23 (41.8%) of the 55 responding patients met the predefined criteria for surgical success. Multivariable analysis identified age younger than 60 years (odds ratio [OR], 4.22; P = 0.02), absence of overactive bladder symptoms before sling release (OR, 3.99; P = 0.04), and type of sling release (sling incision or loosening vs partial or complete excision) (OR, 3.78; P = 0.05) as predictors of success.

Conclusions

Of responders, 23 (41.8%) reported global improvement and satisfaction. Younger age, lack of documented overactive bladder symptoms before sling release, and performing sling release with sling incision or loosening rather than partial or complete excision were associated with better satisfaction and patient-reported improvement.
