Abstract

Abstract: Objective: We aimed to evaluate the efficacy, surgical outcomes, and adverse events of the adjustable midurethral sling I‐stop‐mini in women with intrinsic sphincter deficiency (ISD)–type stress urinary incontinence. We compared this new sling system with the Obtryx transobturator midurethral sling system. Methods: This retrospective cohort study was conducted at a single center from June 2017 to December 2020. A total of 141 women who underwent placement of an I‐stop‐mini or Obtryx and were followed up for at least 1 year were enrolled. ISD was defined as a Valsalva leak point pressure of ≤60 cmH2 O or a maximal urethral closure pressure of ≤20 cmH2 O. Student t test was used to compare continuous variables, and chi‐square test was used to compare the distribution of categorical data. Results: In terms of objective success, I‐stop‐mini and Obtryx showed no significant differences in the postoperative 1‐month, 6‐month, and 12‐month. The two devices showed similar effectiveness regardless of the ISD definition. The I‐stop‐mini group had a significantly shorter operative time, whereas the adverse event rates were similar. Conclusion: The subjective cure rate, objective success, and adverse event rate did not differ in the two devices. I‐stop‐mini had a significantly shorter operative time. Synopsis: I‐stop‐mini, a new adjustable midurethral sling, showed similar efficacy to the transobturator midurethral sling Obtryx in women with stress urinary incontinence and intrinsic sphincter deficiency.
