Long-term outcomes of patients who failed to attend following midurethral sling surgery--a comparative study and analysis of risk factors for non-attendance

Background and aims: To assess long-term subjective cure and subjective complication rates of women who underwent midurethral sling (MUS) for stress urinary incontinence (SUI) in those who failed to attend (FTA) versus those who attended for postoperative follow-up. Predictive factors for non-attendance were identified. Methods: A total of 1225 consecutive women with urodynamic SUI had a synthetic MUS at our institution between 1999 and 2007. Patients were interviewed via phone call with a structured questionnaire. Comparison between FTA and non-FTA patients was performed and multivariate analysis was utilised to identify risk factors for non-attendance. Results: Univariate analysis revealed that the FTA rate was lower in patients who underwent concomitant prolapse surgery (29 vs. 84 , P <0.001), FTA patients were younger (mean age 56 vs. 67 years, P <0.001) and more depressed (14 vs. 4 , P <0.05). At a mean follow-up of 50 ? 24 months, the subjective cure rate was similar between the two groups (84 vs. 86 , NS). The incidence of overactive bladder symptoms was significantly higher in the non-FTA patients (34 vs. 6 P <0.001). Isolated sling procedure (OR = 2.71, P <0.01) and age
