Predictors and outcomes of Mid-urethral sling continence surgeries for stress urinary incontinence among Taiwanese women: What works best?

Abstract

Abstracts: Mid urethral sling (MUS) surgery is a widely accepted and safe procedure performed for stress urinary incontinence (SUI) with excellent cure rate besides its minimal complications. There are various types of MUS which can be offered. In this review we collated published data on MUS surgery performed among Taiwanese women with SUI in search for the best techniques and its outcome. We reviewed 77 articles, searched using PubMed platform related to MUS in USI among Taiwanese women from 1998 to 2023.24 articles, total 2733 participants with at least 12 months follow up after MUS. Objective cure rate for trans-obturator tape (TOT), retropubic sling (TVT, tension vaginal tape), single incision sling (SIS) (Solyx) and SIS (MiniArc) are 80%–92%, 88%–94%, 87%–90% and 87%–91% respectively, while subjective cure is 60%–90% in TOT, 86% in SIS (Solyx) and almost 90% in SIS (MiniArc), Predictors for surgical failure analyzed in 5 papers of 1006 women. Identifiable risk includes low maximal urethral closure pressure, intrinsic sphincter deficiency, previous anti SUI or prolapse surgery, presence of neurogenic disease, constipation, decreased bladder sensation, age >65 years, high pad test, Diabetes, detrusor overactivity, post-menopausal, reduced postoperative urethral mobility and tape percentile. Subsequently we dwell into complications of each type of MUS. This review showed the evolution of MUS and its comparable therapeutic efficacy. However, with certain complication rates and predictors for failure. This will add value in preoperative counselling while taking into accounts patients’ factors in choosing the appropriate types of MUS. Future research is needed on long term effectiveness and risk of future recurrence.
