The evolution of surgical treatment for female stress urinary incontinence: era of mid-urethral slings

A modified Altis® mid-urethral sling that allows immediate post-operative adjustment: experience in 197 patients

OBJECTIVES

The transobturator mid-urethral Altis^® "mini-sling" uses a static and a dynamic anchor on either end of a pulley suture for intraoperative tension adjustment. Given the potential for incorrect tensioning with sling placement, we adopted a modification for post-operative adjustment should stress urinary incontinence (SUI) persist. The objective is to describe technique, rate of postoperative adjustment driven by patient symptoms, and impact of preoperative/intraoperative variables.

METHODS

In this single-surgeon experience, retrospective chart review, demographic and clinical data were collected on patients who received the Altis^® sling for SUI between 2014 and 2019. We used descriptive statistics and three-group comparison tests to assess difference in variables among tightening, loosening, or no adjustment.

RESULTS

Altis^® sling placement was performed on 197 female patients with an average age of 58.7 years. Eighty-four percent (165/197) did not receive post-operative adjustment. Of the 32 patients with post-operative adjustment, 8 (4.1%) had loosening and 24 (12.2%) had tightening at an average of 10.5 days post-operatively. All tightening procedures were done in the clinic. Of the 8 patients with post-operative loosening, 6 were performed in clinic and 2 in the operating room. Preoperative and intraoperative variables were not significantly different among tightening, loosening, and no adjustment cohorts.

CONCLUSIONS

This modification of the Altis^® sling provides surgeons with the ability to tighten and loosen the sling for persistent SUI. All tightening and most loosening procedures were able to be performed in the clinic. The ability to easily tighten a sling in the early post-operative period may be a critical advantage.

Long-Term Results after Suprapubic ARC Procedure for the Treatment of Stress Urinary Incontinence in Women: A Retrospective Data Analysis

INTRODUCTION

The aim of this study was to evaluate long-term safety and efficacy of the suprapubic arc (SPARC) procedure for the surgical treatment of stress urinary incontinence (SUI).

MATERIALS AND METHODS

139 female patients treated by SPARC were included in this retrospective analysis, whereby 126 patients were available for follow-up after 1 year, 70 after 6 years, and 41 after 9 years. The cough test, pad test, uroflowmetry, and post-void residual volume measurements were performed. Severity of bother (visual analogous scale [VAS] 0-10), continence, and the satisfaction rate were assessed. Objective cure was defined as a negative cough test and pad weight ≤1 g, subjective cure as no urine loss during daily activities and no usage of pads. The VAS, pad weight, number of pads per day, and maximal flow rate were compared preoperatively and postoperatively.

RESULTS

Objective cure rates at 1, 6, and 9 years were 78.6, 71.4, and 70.7% and subjective cure rates were 72.2, 55.7, and 65.8%, respectively. The VAS, pad weight, number of pads, and maximal flow rate decreased significantly. Study limitations include a relatively small sample size and the retrospective fashion of the analysis.

CONCLUSIONS

In the long-term context, SPARC showed to represent an efficient and safe procedure for treatment of female SUI.

Endoscopic holmium laser fragmentation and retrieval of migrated intravesical prolene mesh

A 52-year-old man presented with lower urinary tract symptoms and intermittent haematuria for the last 6 months. He had undergone totally extraperitoneal right inguinal hernia repair a decade ago. The ultrasonography and an X-ray of the pelvis suggested a large radio-opaque shadow in the bladder. However, CT revealed an encrusted intravesical extension of the migrated mesh along the right anterolateral wall. The entire intravesical part of the migrated mesh with encrustations was successfully retrieved by endourological approach using holmium laser. The patient symptomatically improved and at follow-up, cystoscopy showed a complete re-epithelisation of the bladder mucosa. The intravesical extension of migrated mesh is a rare but challenging complication following mesh hernioplasty and can be successfully managed with a complete endoscopic approach.

Obesity as a risk factor for poor outcomes after sling surgery in women with stress urinary incontinence: A systematic review and meta-analysis

PURPOSE

Obesity is one of the main risk factors for stress urinary incontinence (SUI) and has also been associated with worse surgical outcomes. However, the literature is heterogeneous and inconclusive. The goal of this study was to perform a systematic review and meta-analysis to evaluate cure rates and perioperative complications in obese women.

MATERIALS AND METHODS

A literature search of OVID, MEDNAR, Embase, Scopus, Web of Science, PubMed, and CENTRAL databases was conducted. Randomized controlled trials comparing cure rates and failure of treatment in normal and obese patients, who underwent mid-urethral sling surgery, were identified. A systematic review of subjective and objective cure rates, and complications was performed. Meta-analyses of dichotomous data under the random-effects model were applied using Review Manager 5.3. Nonrandomized comparative studies and gray literature were excluded.

RESULTS

A total of 219 studies were identified. Four randomized controlled trials were included for evaluation. The risk of bias evaluation was performed according to the Cochrane Handbook for Systematic Reviews of Interventions. One study was excluded due to missing data on the outcomes. Patients were stratified according to their body mass index as obese (>30 kg/m² ) and nonobese (<30 kg/m² ). Complications could not be meta-analyzed. The meta-analysis of subjective (risk ratio [RR] = 1.69 [95% confidence interval [CI]: 1.32-2.16]) and objective (RR = 1.62 [95% CI: 1.26-2.07]) cure rates disfavored obese women.

CONCLUSIONS

This meta-analysis shows that obesity is a risk factor for the nonsuccessful treatment of SUI with tension-free mid-urethral sling. Differences in regards to the surgical approach and its association with obesity could not be established with the current evidence.

Outcomes of transurethral resection (TUR) of intravesical mesh after suburethral slings in the treatment of urinary stress incontinence

OBJECTIVE

The objective of this study was to determine the efficacy as well as the complications associated with transurethral removal (TUR) of intravesical mesh after suburethral sling, transobturator tape-TOT (Monarc™) or "minisling" (MiniArc(®)), in the treatment of female urinary stress incontinence (USI).

MATERIAL AND METHODS

retrospective and consecutive study on 9 women with bladder perforation after midurethral slings (3 Monarc™ and 6 MiniArc®) placement for urinary stress incontinence. To remove the mesh, transurethral resection with an electrode loop (TUR-E) was used. The technique included: location and total removal of mesh with bipolar resectoscope up to healthy tissue.

RESULTS

The median age was 61 years (49-70 years). The median time between midurethral sling placement and onset the sympltoms was 13 months (1-79 months). and between sling placement and mesh removal was 16 months (1-91 months). Five women (55.5%) developed bladder stones. Mean operating time was 29.4 ± 10.4 minutes and mean length of hospital stay was 2.6 ± 0.5 days. The median follow-up after mesh removal was 38 months (range, 14 to 109 months). No complications were found.

CONCLUSIONS

The use of transurethral resection of intravesical mesh after suburethral slings is easy and the results obtained by our surgical team are excellent.

Adjustable vs. ordinary transobturator tape for female stress incontinence. Is there a difference?

Objectives

To determine whether there are any significant differences in complications and success rate between adjustable transobturator tape (TOA) and ordinary transobturator tape (TOT) in the treatment of female stress urinary incontinence (fSUI), as the TOA was recently introduced for the treatment of female SUI, its advantage being the ability to adjust the tape after surgery to address over- or under-correction.

Patients and methods

In all, 96 women with SUI (mean age 53 years, SD 10) were included in the study. Patients were randomised into two equal groups (group 1, TOA, vs. group 2, TOT). The operative duration, blood loss, intra- and post-operative complications, and the success rate, were compared between the groups.

Results

There was no statistically significant difference between the groups in cure rates (83% vs. 80%, groups 1 and 2, respectively) or in postoperative stay. The mean operative duration in group 2 was significantly shorter than in group 1. No intraoperative bleeding requiring a blood transfusion was recorded, and there were no bladder injuries. Postoperative adjustment of the tape was only required in three patients in group 1.

Conclusions

The TOA is a safe and accurate method for treating fSUI, but with experienced surgeons there was no difference in the cure rate and postoperative outcome between TOA and TOT.

One-year outcomes of mid-urethral sling procedures for stress urinary incontinence according to body mass index

Purpose

The purpose of our study was to investigate the safety and efficacy of the suprapubic arch (SPARC) sling operation and the transobturator tape (MONARC) sling operation according to body mass index (BMI).

Materials and Methods

Between January 1, 2004, and July 12, 2009, a retrospective clinical trial was performed with 284 patients treated by the SPARC sling procedure and 49 patients treated by the MONARC sling procedure. The women were classified into 3 groups by BMI according to the WHO Expert Consultation: normal weight (A, BMI 18.5 to 22.9 kg/m²), overweight (B, BMI 23 to 27.5 kg/m²), and obese (C, BMI>27.6 kg/m²). Patients' characteristics and clinical outcomes of the operation were analyzed according to BMI at 1 year after surgery via questionnaires and interviews with the patients about their voiding symptoms and medical records.

Results

There were 103 patients in group A, 186 in group B, and 34 in group C. The objective cure rates for groups A, B, and C after the SPARC procedure were 94.4%, 96.7%, and 96.8%, respectively (p=0.321), and the subjective cure rates were 94.4%, 96.1%, and 96.8%, respectively (p=0.222). The objective cure rates for groups A, B, and C after the MONARC procedure were 100.0%, 90.9%, and 66.7%, respectively (p=0.742), and the subjective cure rates were 92.3%, 93.9%, and 66.7%, respectively (p=0.779). The complication rates were similar among the three study groups.

Conclusions

Mid-urethral sling procedures for urinary incontinence result in similar objective and subjective cure rates and postoperative complications irrespective of BMI.

Proper Mesh Placement Using the Outer Cylinder of a Ballpoint Pen in the Transobturator Adjustable Tape Sling Procedure for Female Stress Urinary Incontinence

Purpose

The transobturator adjustable tape (TOA) sling operation is an effective procedure that allows for correction of postoperative incontinence or obstruction through adjustment of the mesh tension. During the operation, the outer cylinder of a ballpoint pen was used for proper mesh placement with less dissection. We evaluated the efficacy and safety of the TOA sling operation with the use of the outer cylinder of a ballpoint pen.

Materials and Methods

A total of 127 consecutive women with stress urinary incontinence underwent the TOA sling operation with the use of the outer cylinder of a ballpoint pen. The preoperative evaluations included a stress cough test, urodynamic study, and questionnaires related to quality of life. The mesh tension was adjusted 1 day after the operation. Postoperative evaluation was done at 1 month and included a stress cough test, uroflowmetry, questionnaires, and asking about satisfaction. At 1 year, we evaluated the patients with a stress cough test and by asking about their satisfaction with the procedure.

Results

The overall cure rate was 95.3% at 1 month and 96.8% at the 1-year follow-up. Postoperative adjustment of the mesh tension was done for 22 patients (17.3%). Eight patients needed increased tension for remaining stress urinary incontinence, and 14 patients needed reduced tension for urinary obstruction. The maximal flow rate was decreased significantly. However, the residual urine volume was not increased significantly. The total score on the questionnaires increased significantly.

Conclusions

Results were excellent compared with outcomes of the traditional TOA sling procedure. Proper mesh placement by use of the outer cylinder of a ballpoint pen with less dissection and tension adjustment could improve the success rate of the TOA sling operation.

Outcomes of transurethral removal of intravesical or intraurethral mesh following midurethral sling surgery

Purpose

To present outcomes of transurethral removal (TUR) of intravesical or intraurethral mesh after midurethral slings.

Materials and Methods

This was a retrospective chart review of 23 consecutive women: 20 with intravesical mesh and 3 with intraurethral mesh.

Results

To remove the mesh, transurethral resection with an electrode loop (TUR-E) was used in 16 women and transurethral resection with a holmium laser (TUR-H) was used in 7. The median follow-up was 2.1 months. Twenty-six percent of the women (6/23) had a mesh remnant: 6.2% (1/16) of the women treated with TUR-E and 71.4% (5/7) of the women treated with TUR-H. Of the 5 women treated with TUR-H, 3 underwent concomitant transvaginal removal. On the follow-up cystoscopic exam, a mesh remnant was observed in 3 women (1 treated with TUR-E and 2 treated with TUR-H). Vesico-vaginal fistulas were found in 2 women during and after TUR-E, respectively. Stress urinary incontinence recurred in 1 woman.

Conclusions

TUR-E has a high success rate but carries a risk of bladder perforation. Complete resection using TUR-H depends on the location of the mesh and the range of motion of the instrument.

Methicillin-resistant Staphylococcus aureus pelvic abscesses in a female after gynecologic pelvic surgery

Pelvic abscesses occurring after gynecologic pelvic surgery are uncommon. We describe the case of a woman who, after undergoing such a procedure, was found to have pelvic abscesses infected with methicillin-resistant Staphyloccocus aureus. The purpose of this report is to raise awareness of a life-threatening complication of gynecologic pelvic surgery.

Transobturator adjustable tape for severe stress urinary incontinence and stress urinary incontinence with voiding dysfunction

INTRODUCTION AND HYPOTHESIS

This prospective multicenter study was conducted to evaluate the efficacy and safety of an adjustable mid-urethral sling (MUS) using transobturator adjustable tape (TOA) in women with severe stress urinary incontinence or combined stress urinary incontinence (SUI) and voiding dysfunction (VD).

METHODS

One day after placement of TOA, the tension was adjusted. Six months after surgery, changes in several questionnaires and uroflowmetry (UFM) parameters were evaluated.

RESULTS

Among the 65 women enrolled in the study, 27 (41.5%) required postoperative tension readjustments. At 6 months, the complete cure rate of SUI was 84.4%, and patient satisfaction with the operation was 86.2%. There was improvement in the total scores on several questionnaires. There were no significant changes in postoperative UFM parameters.

CONCLUSION

Our results support the use of TOA as an effective modality for the treatment of SUI in women at risk for persistent postoperative SUI or obstructive symptoms.

Comparison of TOA and TOT for Treating Female Stress Urinary Incontinence: Short-Term Outcomes

PURPOSE

The transobturator adjustable tape (TOA) sling operation is a new procedure that allows for the adjustment of tension after surgical intervention, thus permitting correction of postoperative incontinence or obstruction. The aim of this study was to compare the efficacy and safety of TOA with that of the transobturator tape (TOT) procedure.

MATERIALS AND METHODS

Between 2008 and 2009, women with stress urinary incontinence (SUI) underwent TOT (n=63) or TOA (n=40). The preoperative evaluation included history taking, physical examination, voiding diary, stress and 1-hour pad tests, and a comprehensive urodynamic examination. Postoperative evaluation was performed at the 1-week and 3-month postoperative follow-up visits.

RESULTS

The overall cure rate was 90.0% for the TOA group and 85.7% for the TOT group. The rate of satisfaction was higher in the TOA group than in the TOT group (95.0% vs. 85.6%). Four patients in the TOA group needed reduced tension as the result of urinary obstruction. The tension of the mesh was tightened in 1 patient because of a certain degree of continuing incontinence. The residual urine volume was significantly lower in the TOA group than in the TOT group (7.8 ml vs. 43 ml, p=0.01).

CONCLUSIONS

TOA allowed postoperative readjustment for a number of days after surgical intervention, which allowed for good short-term treatment outcomes. These data suggest that better subjective and objective results and residual urine volume can be obtained in the TOA group than those achieved with the traditional non-adjustable mesh and without significant postoperative complications.
