Objective: This study evaluates the outcomes of modified transvaginal mesh (TVM) Surelift in managing advanced pelvic organ prolapse (POP) over a 3-year follow-up period, focusing on surgical success, functional improvement, and sonographic findings.

Methods: A retrospective review was conducted on 99 women who underwent Surelift System surgery for advanced POP Stage III and IV between July 2018 to January 2020. Objective evaluation included Pelvic Organ Prolapse Quantification (POP-Q), multichannel urodynamic (UDS), and introital 2D ultrasonographic measurement.

Objective: Low Maximal Urethral Closure Pressure (MUCP) is linked to unfavourable outcome of anti-incontinence surgery, however the cut-off value varied within studies. This study aimed to predict the cut-off value of MUCP that contributes to poor outcome of Mid-Urethral Sling (MUS) surgery in Urinary Stress Incontinence (USI) patients.

Materials And Methods: Records of 729 women underwent MUS procedure from January 2004 to April 2017 reviewed.

This study aims to assess the medium-term outcomes of UPHOLD-LITE system for treatment of advanced pelvic organ prolapse (POP) and its complications, and lower urinary tract symptoms.

Methods: This is a retrospective case series of 53 months follow-up of 123 consecutive patients who underwent UPHOLD-LITE system.

Introduction And Hypothesis: Our primary objective was to study outcomes of patients with intrinsic sphincter deficiency (ISD) following mid-urethral slings (MUS) at 1-year. Our secondary objective was to delineate factors affecting success in these patients.

Methods: Six hundred eighty-eight patients who had MUS between January 2004 and April 2017 were reviewed retrospectively; 48 women were preoperatively diagnosed with ISD.

Introduction And Hypothesis: Mixed urinary incontinence (MUI) is defined as symptomatic complaint of involuntary leakage associated with urgency and also with exertion, effort, sneezing or coughing. The paucity of research, especially on the surgical management of MUI, limits its best management.

Methods: This is a retrospective study to determine the outcomes of mixed urinary incontinence after mid-urethral sling surgery with two groups, urodynamic stress incontinence (USI) with urgency and urodynamic mixed urinary incontinence (MUI-UD; USI and detrusor overactivity [DO]).

Introduction And Hypothesis: To study the surgical outcomes and risk factors for failure of three types of mid urethral slings(MUS) surgeries in elderly and old age women with urodynamic stress incontinence(USI).

Methods: Three different types of MUS surgeries [single incision sling(SIS), trans-obturator tape(TOT), retro-public mid-urethral sling-tension-free vagina tape (TVT)]were performed among three age groups of women (young <64 yr, elderly 65-74 yr and old >75 yr) with USI. They were followed up for 1 year.

Objective: To compare the ultrasonographic positional changes of mid-urethral sling(MUS) tape in relation to symphysis pubis, and the different clinical outcomes among women who underwent MUS insertion with MiniArcTM or MonarcTM for the treatment of stress urinary incontinence 3 years after.

Materials And Methods: A retrospective follow-up study on patients with clinically confirmed stress urodynamic incontinence and urodynamic stress incontinence who had undergone MiniArc or Monarc surgery. Data regarding preoperative evaluation, intraoperative complications and post-operative follow-ups were collated.

Introduction And Hypothesis: Our primary objective is to determine the presence of SUI at 6-12 months after surgery. The secondary objective is to determine the objective and subjective outcomes of POP.

Methods: A retrospective study conducted between February 2015 and July 2016 at Chang Gung Memorial Hospital.

Objective: To compare the clinical efficacy, recurrence, complications and quality of life changes 3 years after Elevate-A/single incision mesh surgery anterior apical (SIM A) and sacrospinous ligament fixation (SSF) in the management of pelvic organ prolapse (POP).

Materials And Methods: A prospective cohort study, 139 women, underwent transvaginal surgery for anterior and/or apical POP > stage 2, 69 patients had SIM A and 70 patients had SSF. The objective cure was defined as POP ≤ stage 1 anterior, apical according to POP-Q.

Aim: By investigating the association of urodynamics and urogenital nerve growth factor (NGF) levels in vaginal mesh surgery, we may be able to associate the likelihood of postoperative lower urinary tract symptoms developing as a result of synthetic mesh implanted for pelvic floor reconstructive surgery.

Methods: Thirty-eight female Sprague-Dawley rats were divided into three groups: mesh, sham (no mesh), and control. Urodynamic study and NGF analysis of the urogenital tissues were done and results were compared among all groups.

Objective: Voiding dysfunction following a midurethral sling procedure is still a relevant consequence that can affect patients' quality of life. Various invasive methods have been described to manage this problem. We hypothesize that we if we could diagnose the condition early using noninvasive tools, we would be able to offer appropriate effective management.

Introduction And Hypothesis: We hypothesized that transobturator tape (TOT) is safe and efficacious for the treatment of urodynamic stress incontinence in the long term.

Methods: We conducted a prospective study of patients with confirmed urodynamic stress incontinence (USI) who underwent a Monarc TOT procedure in a tertiary center between February 2006 and March 2009 without other concurrent surgical procedures. Urodynamics were conducted at 1 and 3 years postoperatively.

Objective: To evaluate the sonologic and clinical outcome of collagen coated (CC) versus non-collagen coated (NC) anterior vaginal mesh (AVM) for pelvic organ prolapse (POP) surgery.

Study Design: The study is a prospective observational study which included 122 patients who had symptomatic POP stage III and IV. AvaultaPlus™ (collagen coated, CC group) was compared to Perigee™ (non collagen coated, NC group).

Introduction And Hypothesis: To study the outcomes following repeat midurethral sling (MUS) surgery in patients with persistent or recurrent stress urinary incontinence after failure of primary MUS surgery and risk factors for surgical failure.

Methods: The medical records of 24 patients who underwent repeat MUS surgery at a single tertiary center from January 2004 to February 2014 were reviewed. The types of MUS used for the repeat surgey were transobturator, retropubic and single incision slings.

Introduction: To clinically and sonographically evaluate the influence of anterior vaginal mesh (AVM) surgery with concomitant mid-urethral sling surgery (MUS) for stress urinary incontinence (SUI).

Materials And Methods: Women with severe symptomatic pelvic organ prolapse (POP) stage III or IV with concomitant SUI were divided into two groups: Group I had transobturator tape (TOT) and AVM surgery and Group II underwent TOT without AVM surgery. Clinical outcome was assessed pre-operatively and 1 year post-operatively, while ultrasound evaluations were performed after one year.

Objective: The objective of this study was to estimate the association of vaginal sacrospinous ligament fixation with anterior-transobturator mesh repair surgery for advanced pelvic organ prolapse in patients of two different age groups.
