Mini-slings non-inferior to mid-urethral slings for female stress urinary incontinence: NEJM
USA: A recent study in the New England Journal of Medicine showed single-incision mini-slings to be noninferior to standard mid-urethral slings in women with stress urinary incontinence with regards to patient-reported success at 15 months. Also, at the 36-month follow-up, the percentage of patients reporting success remained similar in the two groups.
Synthetic mid-urethral slings (made of mesh or tape) are the standard surgical treatment globally for female stress urinary incontinence in cases of failure of conservative management. However, there is a lack of data comparing the safety and effectiveness of newer single-incision mini-slings with those of standard mid-urethral slings. To fill this knowledge gap, Mohamed Abdel-Fattah and colleagues performed a pragmatic, multicenter, noninferiority, randomized, controlled trial (the SIMS trial) comparing outcomes of adjustable anchored mini-slings with those of tension-free mid-urethral slings in women with stress urinary incontinence at 21 U.K. hospitals during 36 months of follow-up.
Patient-reported success defined as a response of very much or much improved on the Patient Global Impression of Improvement questionnaire at 15 months after randomization (approximately 1 year after surgery) was the primary outcome. The noninferiority margin was 10 percentage points.
298 women were assigned to receive mini-slings and 298 were assigned to receive mid-urethral slings.
Key findings of the study include:
To conclude, single-incision mini-slings were noninferior to standard mid-urethral slings with respect to patient-reported success at 15 months, and the percentage of patients reporting success remained similar in the two groups at the 36-month follow-up.
