Analysis of the Completely Dry Rate Over Time After Mid-urethral Sling in a Real-world Clinical Setting

The impact of partially absorbable midurethral slings in stress urinary incontinence surgery: a cohort study

OBJECTIVES

To evaluate the performance of retropubic midurethral slings (MUS) for the treatment of female stress urinary incontinence (SUI) of a certified continence center and to identify risk factors for sling failure.

METHODS

This was a single-center cohort study including women, who underwent retropubic MUS procedure for SUI between 2012 and 2019 with a follow-up of 12 months. Primary endpoint was cure of SUI assessed by the validated questionnaire International Consultation of Incontinence-Questionnaire-Urinary Incontinence-Short Form. Univariate and multivariate analyses were applied to identify risk factors for sling failure. Wilcoxon signed-rank tests were used as paired samples tests. The significance level was set at 5%.

RESULTS

662 women with a median age of 65 (IQR 19) were included in the investigation. 523 (79.0%) presented with complicated SUI. Cure was reported by 213 (32.2%) women. Independent predictors for failure were obesity, pharmacotherapy for overactive bladder, postoperative sling adjustment and the utilization of partially absorbable mesh (PAS). PAS correlated with a 56% decrease in the odds for achieving cure.

CONCLUSIONS

This investigation questions the role of partially absorbable mesh for stress urinary incontinence procedures and hereby scrutinizes the utilization of implants with inadequate clinical evidence.

Long-term outcomes of transobturator suburethral tapes for female stress urinary incontinence

AIMS

The aim is to evaluate long-term effectiveness and safety of transobturator midurethral slings (TO-MUS) for treating female stress urinary incontinence (SUI). Possible risk factors for failure and complications are also evaluated.

METHODS

A descriptive retrospective study was performed among women with SUI treated at a tertiary urogynecology unit between January 2004 and December 2006. Women with stress-predominant mixed urinary incontinence or with associated pelvic organ prolapse were also included. Postoperative follow-up was performed at 1, 6, and 12 months and yearly thereafter. Outcomes were classified as cured, improved or failed.

RESULTS

Of 896 women operated on over the study period, 565 were suitable for the analysis. Of them, 327 women completed the 5-year, 225 the 7-year, and 172 the 10-year follow-up periods. Success rates were 77.6%, 73.8%, and 73.2% at 5, 7, and 10 years, respectively. On multivariate Cox regression models age, body mass index, and previous incontinence surgery were related to failure. Complications of any type were described in 24.9% of patients, although most of them were mild. Only concomitant prolapse surgery was related to intraoperative and peroperative complications and the inside-out route to an increased odds of groin pain (odds ratio = 4.0).

CONCLUSIONS

This study showed that TO-MUS is an effective and safe procedure in the long-term. The expected outcomes and possible side effects profile should be discussed in detail during the counseling process before opting for a treatment option.

Outcomes collected in female pelvic floor surgical procedure registries and databases: a scoping review

INTRODUCTION AND HYPOTHESIS

The objective was to overview the literature on the existing pelvic floor procedure registries and databases and to identify patient demographic, clinical and/or patient-reported data items for inclusion in the Australasian Pelvic Floor Procedure Registry (APFPR) Minimum Data Set (MDS).

METHODS

We conducted a literature search on the MEDLINE, Embase, CINAHL and PsycINFO databases in addition to Google Scholar and grey literature to identify studies in the period January 2008 to January 2020. All were English studies of registries and databases on female adults undergoing surgery for pelvic floor disorders including stress urinary incontinence (SUI) and pelvic organ prolapse (POP). Studies were assessed on demographic and clinical patient characteristics, procedure or treatment type, health-related quality of life, adverse events and safety outcomes, captured by pelvic floor procedure registries or databases that have been established to date.

RESULTS

From 1662 studies, 29 publications describing 22 different pelvic floor registries and databases were included for analysis, 12 (55%) of which were multicentre. Six (27%) registries and databases involved solely SUI, eight (36%) were regarding POP, and the remaining eight (36%) focussed on both conditions. The majority of registries and databases captured similar details on patient characteristics, comorbidities and other clinical features, procedure or treatment type, health-related quality of life, adverse events, safety and efficacy.

CONCLUSION

The findings of this scoping review will assist in determining the MDS for the APFPR, an initiative of the Australian government, to improve health and quality of life outcomes of women who undergo pelvic floor reconstructive procedures.

Predictors of further anti-incontinence interventions or transvaginal urethrolysis after a pubovaginal sling procedure in women with and without neurologic disorders

BACKGROUND/PURPOSE

The impact of neurologic disorders on the clinical outcome of suburethral sling procedures has seldom been studied. Our aim is to elucidate factors predicting further anti-incontinence interventions or transvaginal urethrolysis after a re-adjustable pubovaginal sling procedure (PVS), especially in patients with neurologic disorders.

METHODS

Medical records of all consecutive women who underwent re-adjustable PVS for stress urinary incontinence (SUI) were reviewed.

RESULTS

A total of 589 women were enrolled, 152 (25.8%) women were found to have persistent or recurrent SUI after surgery, and 39 (6.6%) women underwent further anti-incontinence interventions. Postoperative voiding dysfunction was found in 46 (7.8%) women, and 23 women (3.9%) underwent transvaginal urethrolysis. Low body mass index (hazard ratio = 0.92) and low functional bladder capacity (dL, hazard ratio = 0.83) were factors predicting the presence of persistent/recurrent SUI. However, the presence of spinal cord disorder (hazard ratio = 8.91) and a history of prior surgery for pelvic organ prolapse (hazard ratio = 2.51) were factors predicting further anti-incontinence interventions. A high post-void residual volume (PVR, dL, hazard ratio = 1.52) and preoperative bladder outlet obstruction (BOO, hazard ratio = 5.39) were factors predicting postoperative voiding dysfunction. Similarly, a high PVR (dL, hazard ratio = 1.50) and preoperative BOO (hazard ratio = 5.38) were factors predicting transvaginal urethrolysis. A PVR >1.51 dL was an optimal cut-off value for predicting transvaginal urethrolysis.

CONCLUSION

The presence of spinal cord disorder and prior surgery for pelvic organ prolapse were predictors of further anti-incontinence interventions after re-adjustable PVS. In addition, a large PVR and preoperative BOO were predictors of transvaginal urethrolysis after re-adjustable PVS.

Long-term outcomes of transobturator midurethral slings: A critical evaluation of a real-world population

AIMS

The American Urological Association/Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction stress urinary incontinence (SUI) guidelines strongly recommend the midurethral sling (MUS) for the index female patient with SUI. While numerous studies report long-term outcomes and complications for the retropubic MUS, these are largely absent for the transobturator MUS and are assessed in this study.

METHODS

This is an Institutional Review Board approved retrospective chart review of all women who underwent a transobturator MUS at a single institution from 2004 to 2010. Pre- and postoperative assessment included a cough-stress test, SEAPI assessment, and validated quality-of-life (QoL) questionnaires. SUI resolution was defined as no subjective or objective SUI, and no additional surgery to achieve stress continence.

RESULTS

Of 437 women, 305 (70%) had a minimum follow-up of 48 months (mean 88; median 92). SUI was resolved in 69% of the entire cohort and 58% of the 78 women who had MUS only. The median time to SUI recurrence was 38 months in the entire cohort and 18 months in the MUS only group. Perioperative complications were infrequent and typically associated with concomitant surgery. A statistically significant improvement was observed in SEAPI scores and all QoL indices postoperatively.

CONCLUSIONS

Long-term resolution of SUI after the transobturator MUS is achieved by 69%, which is commensurate with success rates reported in the literature. Overall, women experience a significant improvement in their QoL after transobturator MUS; however, late recurrences and delayed sequelae may occur. Thus, long-term follow-up is warranted in this population.
