摘要
Mid-urethral synthetic slings (MUSS) have grown in acceptance and popularity to gain a foremost position in stress urinary incontinence (SUI) surgery.
There are numerous studies that provide a large amount of Level 1 and 2 evidence that support the concept of a sling placed at the level of the mid-urethra.
Long-term follow-up has been published for the original tension-free vaginal tape (TVT) procedure with the most recent publication providing Level 2 evidence with mean follow-up of 11.5 years of 69/91 (77%) of patients from the original series. There was objective cure was in 90% of women and 77% considered themselves subjectively cured, based on the Patient Global Impression of Improvement.
Level 1 evidence with long-term follow-up has been provided comparing colposuspension to TVT at 2 and 5 years. At 5 years for the primary efficacy variable of a negative 1 h stress pad test, there was no difference in success (81% vs 90%).
Two recent meta-analyses provide Level 1 evidence comparing outcomes for retropubic vs transobturator MUSS. One included 18 studies, randomized and cohort: cohort studies had a 12.3% failure rate for transobturator and 13.7% failure for the retropubic approach, randomized studies showed 5.7% failure in the transobturator vs 7.8% in the retropubic group. The other meta-analysis included 11 studies published 2008-2009, which found that the short-term cure rate was borderline inferior for the transobturator tape group (odds ratio 0.62; 95% confidence interval 0.37-1.00), nearly reaching statistical significance (P = 0.05).
This review details further comparator evidence and evidence for use in specific patient groups (elderly, obese, intrinsic sphincter deficiency, mixed UI).
