摘要：The objective of the study was to compare detrusor overactivity and urge urinary incontinence rates after midurethral slings versus bladder neck slings. Study design: Three hundred forty subjects underwent midurethral slings or bladder neck slings. Comparisons were made using Student s t test and χ 2 test. Multivariate analysis was performed to detect confounding factors. Results: More patients in the midurethral sling group resolved detrusor overactivity than in the bladder neck sling group (38% versus 15% , P < .001). In addition, subjects in the midurethral sling group had significantly lower rates of de novo detrusor overactivity than subjects in the bladder neck sling group (29% versus 62% , P = .002). The only significant predictors of postoperative detrusor overactivity were preoperative detrusor overactivity (P < .001) and sling type (P < .001). After adjusting for preoperative detrusor overactivity, bladder neck slings significantly increased the risk for persistent detrusor overactivity (odds ratio 3.9). Conclusion: Midurethral slings have increased rates of resolution of detrusor overactivity and lower rates of de novo detrusor overactivity than transvaginal bladder neck sling procedures.
