Long-term Outcomes of 100 Transobturator Tape Procedures

Aim Satisfactory short-term outcomes of transobturator tapes (TOTs) are recognized, yet a lack of long-term data exists. We investigated long-term patient-reported outcomes of TOTs. Methods A retrospective review was performed of 100 female patients post TOT insertion by a single surgeon (2005-2010). Results and postoperative complications were identified. At long-term follow-up, patients completed ICIQ-Short Form, PGI-S and PGI-I questionnaires. Results Mean age was 51.7 years (33-75), mean follow-up 9.4 years (7.25 - 12.75). Clinically, 68/100(68%) had mixed and 32/100(32%) pure stress urinary incontinence (SUI). Short-term cure/significant improvement in SUI was seen in 98/100(98%). Grade >2 Clavien-Dindo complications occurred in 10/100(10%) within 6 months of surgery. Long-term questionnaire response rate was 76/100(76%). 62/76 (81.57%) described current urinary condition as "much" or "very much" "better." No new complications emerged at long-term follow-up. Conclusion TOTs demonstrate high success rates in treatment of SUI, with no late-onset complications identified in our study. Recent concerns surrounding use of polypropylene tapes make reporting of long-term outcomes both desirable and necessary.

[Short-term evaluation of Altis® single-incision sling in women stress urinary incontinence]

INTRODUCTION

Midurethral slings are the main surgical treatment of stress urinary incontinence. Altis is a minimally invasive single-incision sling system. The aim of this study is to report the safety and efficacity results during a year of follow up.

MATERIALS AND METHODS

This single-centre and retrospective study has been performed in a university hospital, between February 2015 and May 2018. We included women aged more than 18, complaining a stress urinary incontinence with a urethral hypermobility and positive support maneuvers, who had failed from non surgical treatment. A prospective data collection has been done at the moment of inclusion, peroperative time, at 6 weeks, 6 months and a year after the procedure. The main evaluation criteria was the cure rate at twelve months.

RESULTS

Thirty patients were included in our study. The mean age was 45,4±12,9 years old, the mean ICIQ-UI score was 13,5±4,06 and the median pad test was at 12g. Ninety three percent of the procedures were done as ambulatory surgery. The average operating time was at 22,2minutes. Overall, 75% of our patients were objectively cured and 14,2% were in fail of this treatment.

CONCLUSION

The short term results show a good efficacity and safety of this procedure. But its place remains to be defined in relation to other techniques, TVT, TOT and non-prosthetic techniques.

A comprehensive look at risk factors for mid-urethral sling revision surgery

INTRODUCTION

The objective of this study was to identify risk factors and urodynamic parameters predictive of mid-urethral sling (MUS) revision surgery that can be used for counseling patients and individualizing risk prediction.

METHODS

Retrospective case-control analysis of 40 sling revisions performed during the 12-year study period were compared to 123 control cases that did not require revision to obtain a 1:3 case-to-control ratio. Demographic, perioperative, and urodynamic data were analyzed, with p < 0.05 as significant. Independent predictors of sling revision were assessed by binary logistic regression models, with risk expressed as adjusted odds ratios.

RESULTS

After multiple regression analysis, younger age at time of index MUS placement (aOR 0.93, 95% CI 0.88-0.97), increasing number of cesarean deliveries (CD) (aOR 2.00, 95% CI 1.01-3.96), and concomitant apical prolapse repair during index MUS procedure (aOR 4.63, 95% CI 1.34-15.93) were significant predictors of sling revision.

CONCLUSIONS

Young age at the time of placement, multiple CD, and concomitant apical prolapse repair were independent factors predictive of sling revision. Giving consideration to risk factors could improve patient counseling and surgical candidate selection.

Radical excision of a complicated transobturator tape

AIM OF THE VIDEO

In this video, we present the case of a late-detected sinus formation 4 years after a TOT placement.

METHOD

A combined surgical approach (transvaginal and transcutaneous routes) performed by a urogynecologist and an orthopaedic surgeon was chosen to carry out a radical en bloc excision of the sinus tract with the right half of the tape. This combined approach has the advantage of completely removing the biofilm adhered to the surface of the tape and the surrounding tissues, thus making antibiotic therapy more effective.

CONCLUSION

Surgical removal of these microbial commmunities is very important for the resolution of device-related infections. Severe infectious complications of transobturator slings should be managed by a tertiary multidisciplinary team to optimize patient care.

Long-term outcomes of retropubic tension-free vaginal tape for stress urinary incontinence after a transobturator tape failure: a retrospective study

INTRODUCTION AND HYPOTHESIS

Management of stress urinary incontinence (SUI) after a transobturator tape (TOT) failure is a controversial issue. There are few long-term data on the different treatment options. The aim of this study is to evaluate the long-term effectiveness and safety of retropubic suburethral slings (RP-TVT) in this setting.

METHODS

A descriptive retrospective study was performed among women with persistent/recurrent SUI treated at the Vall d'Hebron University Hospital between January 2006 and December 2014. All women were preoperatively evaluated to rule out complications of the first sling. Postoperative follow-up was performed at 1, 6 and 12 months and yearly thereafter. Outcomes were classified as cured, improved or failed.

RESULTS

Forty-one women were operated on over the study period. The median follow-up time was 103.2 months. Likelihood to be cured or improved at 3, 5, 7 and 10 years was 78.0%, 75.4%, 71.9% and 67.4%, respectively. Absence of urethral hypermobility was the only variable related to RP-TVT failure. Complications during follow-up were observed in 39% of patients, although most of them were mild. However, two cases (4.9%) of vaginal exposure and three (7.3%) of lower urinary tract extrusion were observed. De novo urgency occurred 17.1% of women.

CONCLUSIONS

RP-TVT showed reasonable long-term effectiveness but had a high overall complication rate in the treatment of persistent/recurrent SUI after TOT. Expected outcomes and possible side effects should be discussed in detail during counseling before opting for a treatment option.

Multidimensional outcomes of suburethral synthetic midurethral sling removal

PURPOSE

To report multidimensional outcomes encompassing pain, dyspareunia, and recurrent urinary tract infections (UTIs), following suburethral sling removal (SSR) of synthetic midurethral slings (MUS) placed for female stress urinary incontinence.

METHODS

We reviewed a prospectively maintained, IRB-approved database of women undergoing SSR at our institution. Demographic data, type of sling, and symptoms along with Urogenital Distress Inventory-Short Form (UDI-6) scores both before and after SSR were analyzed. Success was defined using several modalities including patient-reported symptoms (ideal outcome) and UDI-6 questionnaire.

RESULTS

From 3/2006-2/2017, 443 women underwent SSR of which 230 met study criteria with median overall follow-up of 23 months (mean 30 months). 180/230 (78%) patients reported 3 or more symptoms at presentation. Median most recent post-SSR total UDI-6 score was 38 vs. 50 at baseline (p < 0.0001). By UDI-6, 53% of patients achieved success post-SSR. An ideal outcome was attained in 22/230 (10%) patients. A modified outcome allowing for one minimally invasive anti-incontinence procedure and excluding sexual activity classified 112/230 (49%) patients as successes.

CONCLUSIONS

While patients with MUS present with multiple symptoms, following SSR, there is sustained improvement in multiple symptom domains, including pain and urinary incontinence. Allowing for minimally invasive anti-incontinence procedures (not inclusive of subsequent suburethral sling), the rate of success was 49%, which was comparable to that derived from UDI-6 scores (53%).

Mesh induced fibrosis: The protective role of T regulatory cells

Polypropylene mesh is widely used in urogynecologic surgery, but complications rates (pain and exposure) approach 10%. Emerging evidence implicates the adaptive immune system in regulating the foreign body response to mesh, particularly regulatory T cells (T_regs), which modify macrophage differentiation and down-regulate CD8⁺ effector T cells. We hypothesize that T_regs protect against a profibrotic response, a likely mechanism of pain complications. Here, thin sections of mesh-tissue complexes removed for the primary complaint of pain (N = 14) or exposure (N = 15) were labeled for CD8, CD4 (T_h), and FoxP3 (T_regs) via immunofluorescence. The same sections were analyzed for localized collagen deposition via a customized semi-quantitative assessment (0.25 mm² grid) after trichrome staining. TGF-β1 concentrations were determined by enzyme-linked immunosorbent assay. Fewer T_reg and CD4⁺ cells were found in fibrotic areas versus non-fibrotic areas (503 and 550/cm² fewer, respectively, both P < 0.001). TGF-β1 was higher in mesh samples compared to autologous control biopsies. TGF-β 1 inversely correlated with age, r -0.636(p = 0.008). No differences were found in T cell subgroups or fibrotic indices between pain and exposure groups. A moderate inverse relationship was found between TGF-β1 and T_regs (r -0.402, P = 0.009)_. T_regs were present up to 12 years after mesh implantation, challenging the assumption that the adaptive immune response to a foreign body is transient. In conclusion, the inverse relationship between fibrosis and T_regs, and TGF-β1 and T_regs points to a protective role of these cells. Similar immunologic responses in patients with pain and exposure suggest these complications exist along a spectrum. STATEMENT OF SIGNIFICANCE: The use of polypropylene mesh has been associated with improved outcomes in urogynecologic surgery, but is associated with significant complications, including pain and exposure through the vaginal epithelium. The host immune response features a prolonged inflammatory reaction containing innate immune cells and T lymphocytes clustered in capsules around the mesh fibers. This study uncovers the inverse relationship between T regulatory cells and the extent of fibrosis around the mesh, suggesting an anti-fibrotic effect. In addition, concentrations of T regulatory and T effector cells and levels of fibrosis connect these two most common complications into one mechanistic pathway. These new insights into the immune response to implanted mesh are an important step in understanding the causes of these surgical complications.

Management of Occult Urinary Incontinence with Prolapse Surgery

PURPOSE OF REVIEW

The purpose of this paper is to review (1) the epidemiology and pathophysiology of pelvic organ prolapse (POP) and occult stress urinary incontinence (SUI), (2) examine the data on combined operative management of POP and occult SUI, (3) discuss the approaches to clinical decision making, and (4) present future therapies.

RECENT FINDINGS

Prospective data on many approaches to concomitant treatment of prolapse and occult stress urinary incontinence, such as minimally invasive sacrocolpopexy and midurethral sling, or older approaches that have regained favor among patients and clinicians wishing to avoid synthetic mesh, such as native tissue prolapse repair and pubovaginal sling, are limited. Safe durable treatments with absorbable graft materials that promote a beneficial host response are intriguing but may be far from clinical implementation. Stem cell therapy for the treatment of stress urinary incontinence has demonstrated benefit in phase I/II trials but has not been studied in the setting of concomitant treatment of occult SUI with POP surgery and remains in the preclinical phase for the treatment of POP. A personalized approach to concomitant SUI surgery that incorporates individual risk assessment as well as informed patient preferences likely optimizes the risk/benefit ratio and patient satisfaction. Novel therapies, including graft materials and cellular therapies that stimulate a regenerative response, may improve or maintain continence outcomes while mitigating risk and alter the approach to both POP and SUI surgery.

Should we combine vaginal prolapse surgery with continence surgery?

The risk of postoperative stress urinary incontinence (SUI) can be reduced by combining prolapse repair with continence surgery. However, more women face a serious adverse event (SAE) after vaginal prolapse surgery combined with a midurethral sling (MUS). It is difficult to predict a woman's individual postoperative SUI and SAE risk; therefore, weighing the benefits and risks of combination surgery is complex. We offer a concept that might help in considering combination surgery. According to this concept, women whose risk of needing subsequent surgery for postoperative SUI is on average 9% are likely to benefit from combination surgery.

National BSUG audit of stress urinary incontinence surgery in England

Introduction and hypothesis

The aim of the British Society of Urogynaecology (BSUG) 2013 audit for stress urinary incontinence (SUI) surgery was to conduct a national clinical audit looking at the intra- and postoperative complications and provide outcomes for these procedures. This audit was supported by the Healthcare Quality Improvement Partnership (HQIP) and National Health Service (NHS) England.

Methods

Data were collected for all continence procedures performed in 2013 through the BSUG database. All clinicians in England performing SUI surgery were invited to submit data to a central database. Outcomes data for the different continence procedures were collected and included intraoperative and postoperative complications and the change in continence scores at postoperative follow-up Changing trends in stress incontinence surgery were also assessed.

Results

We recorded 4993 urinary incontinence procedures from 177 consultants at 110 centres in England: 94.6% were midurethral slings; 86.7% (4331) were submitted by BSUG members with the remaining 13.3% submitted by non-BSUG members. Postoperative follow-up data were available for 3983 (80%) patients: 92.3% (3676) were very much better/much better postoperatively, and 4806 (96.3%) proceeded with no reported complications. There were 187 cases (3.7%) in which a perioperative complication was recorded. Pain persisting >30 days was reported in 1.9% of all patients.

Conclusions

Surgery for SUI has good outcomes in the short term. Midurethral synthetic slings have been shown to be safe and effective as a treatment option, with >90% being very much/much better at their postoperative follow-up.

An Internet-based survey to evaluate the comfort and need for further pubovaginal sling training

INTRODUCTION AND HYPOTHESIS

The pubovaginal sling (PVS) dates to the 1940s as an efficacious surgical treatment for stress urinary incontinence (SUI). Recently, it has been replaced by the midurethral sling (MUS). Since 2008, international regulatory agencies increased regulation and issued warnings on vaginal mesh for repair of pelvic organ prolapse (POP), which has led to increased scrutiny of the MUS. Thus, the need for surgical comfort with PVS is resurfacing. We sought to evaluate the surgical practice patterns among international urogynecologists for the treatment of SUI and identify whether a need and interest for more training exists.

METHODS

We developed a short, Internet-based survey for members of the International Urogynecological Association (IUGA). Descriptive analyses, binomial and multivariate logistic regressions were calculated to determine significant associations.

RESULTS

Among 556 members who responded to the survey, 72% did not offer PVS in practice. Among those who did, there was as significant relationship between offering PVS and practicing in the United States, board-certification in urogynecology, PVS exposure in training, increasing number of PVS performed during training, and comfort with PVS. Members interested in further PVS training were younger, less comfortable with PVS, performed fewer PVS, or had no exposure in training.

CONCLUSION

Most IUGA members do not offer PVS in clinical practice. As would be expected, members who performed more PVS in training and were more comfortable with PVS were likely to offer it to patients. Our results highlight a learning gap, especially among younger providers who are not comfortable with PVS and desire further training in this procedure.

Road to recovery after transvaginal surgery for urethral mesh perforation: evaluation of outcomes and subsequent procedures

INTRODUCTION AND HYPOTHESIS

Urethral injury resulting from transvaginal mesh slings is a rare complication with an estimated incidence of <1%. Our objective was to review the surgical management and functional outcomes of women presenting with urethral mesh perforation following midurethral sling (MUS) placement.

METHODS

This was a retrospective multicenter review of women who from January 2011 to March 2016 at two institutions underwent mesh sling excision for urethral perforation with Female Pelvic Medicine and Reconstructive Surgery fellowship-trained surgeons. Data comprising preoperative symptoms, operative details, and postoperative outcomes were collected by telephone (n 13) or based on their last follow-up appointment.

RESULTS OBTAINED

Nineteen women underwent transvaginal sling excision for urethral mesh perforation. Eight (42%) patients had undergone previous sling revision surgery. Sixty percent of women had resolution of their pelvic pain postoperatively. At follow-up, 92% reported urinary incontinence (UI), and three had undergone five additional procedures for vaginal prolapse mesh exposure (n 1), incontinence (onabotulinum toxin injection n 1, rectus fascia autologous sling n 1), prolapse (colpopexy n 1), and pain (trigger-point injection n 1). Patient global impression of improvement data was available for 13 patients, of whom seven (54%) rated their postoperative condition as Very much better or Much better.

CONCLUSIONS

The management of urethral mesh perforation is complex. Most women reported resolution of their pelvic pain and a high rate of satisfaction with their postoperative condition despite high rates of incontinence.

Robotic-assisted Sacrocolpopexy with versus without Concomitant Midurethral Sling: A 2-year Follow-up of Urinary Symptoms and Quality of Life

OBJECTIVE

The objective of this study was to assess long-term postoperative urinary incontinence (UI) symptoms and quality of life (QOL) in patients after robotic-assisted sacrocolpopexy (RASC) with or without concomitant midurethral sling (MUS).

MATERIALS AND METHODS

This is a cross-sectional survey of patients comparing long-term postoperative urinary symptoms and QOL measurements in women who underwent RASC with or without MUS. We included all patients from 2011 to 2014 who had RASC with or without MUS. All patients had preoperative urodynamic testing (UDS). Patients who demonstrated stress UI on UDS underwent MUS at the time of RASC. Urinary symptoms and QOL were assessed through the validated Urinary Distress Inventory-6 (UDI-6) and Incontinence Impact Questionnaire-7 (IIQ-7) patient questionnaires.

RESULTS

Sixty-eight patients met inclusion criteria, 46 patients completed follow-up questionnaires, and were included in the final analysis. Average length of time to follow-up from surgery was 24 months (range: 6-36 months). A statistically significant difference in UDI-6 scores between the two groups (RASC vs. RASC + MUS) was observed. Median (25th and 75th percentiles) scores for UDI-6 were 22.92 (8.33 and 32.29, respectively) for the RASC group and 4.17 (0 and 13.54, respectively) for the RASC + MUS group (P = 0.0017). Median scores for IIQ-7 were 0 (0 and 29.73 for the 25th and 75th percentiles, respectively) for the RASC group and 0 (0 and 0, respectively) for the RASC + MUS group (P = 0.1691).

CONCLUSION

Patients who underwent RASC + MUS scored significantly lower on the UDI-6, indicating fewer urinary distress symptoms. Although not statistically significant, patients in the RASC + MUS group had lower IIQ-7 scores, indicating less negative impact on QOL, compared to the RASC-only group.

Management of post-midurethral sling voiding dysfunction. International Urogynecological Association research and development committee opinion

Voiding dysfunction following midurethral sling procedures is not a rare event. There is no current consensus regarding management of this complication. Although it is often transient and self-limiting, chronic post-midurethral sling voiding dysfunction may lead to irreversible changes affecting detrusor function. Initial management includes intermittent catheterization, and addressing circumstantial factors interfering with normal voiding, such as pain. Early sling mobilization often resolves the dysfunction, and is associated with minimal morbidity. Sling incision or excision at a later stage, although fairly effective, could be associated with recurrence of stress urinary incontinence. There is insufficient evidence to justify urethral dilatation in this context.

Informed consent checklists for midurethral slings: a common-sense approach

INTRODUCTION AND HYPOTHESIS

Following the US Food and Drug Administration's (FDA's) warning about the use of transvaginal mesh to treat pelvic organ prolapse (POP) and the use of single-incision slings to treat incontinence, the number of lawsuits for medical negligence regarding the use of any polypropylene mesh in the vagina has increased tremendously.

METHODS

This same FDA document did not question the use of polypropylene midurethral slings and polypropylene for sacrocolpopexies. Surprisingly, despite all the evidence and recommendations from respected international scientific societies, we are constantly being called upon by our patients to defend the use of midurethral slings. The most common reasons for the new rash of medicolegal proceedings involving midurethral slings has to do with "breach of duties" resulting from undisclosed postoperative complications on the consent form and/or the lack of information in the medical records confirming that all possible alternative treatment options were presented to and discussed with the patient.

RESULTS

One response to these lawsuits involves the addition of preoperative checklists when performing informed consent with patients electing surgical correction of stress urinary incontinence (SUI).

CONCLUSIONS

This clinical opinion provides an expert clinician's perspectives and legal point of view on this controversial topic and discusses the role of a preoperative checklist supplementary to the standard informed consent form.

One normal void and residual following MUS surgery is all that is necessary in most patients

INTRODUCTION AND HYPOTHESIS

There is considerable variation worldwide on how the assessment of voiding function is performed following midurethral sling (MUS) surgery. There is potentially a financial cost, and reduction in efficiency when patient discharge is delayed. Using our current practice of two normal void and residual (V&R) readings before discharge, the aim of this retrospective study was to evaluate the likelihood of an abnormal second V&R test if the first V&R test was normal in order to determine if a policy of discharge after only one satisfactory V&R test is reasonable.

METHODS

Data from 400 patients who had had MUS surgery with or without other procedures were collected. Our unit protocol included two consecutive voids of greater than 200 ml with residuals less than 150 ml before discharge. The patients were divided into the following groups: MUS only, MUS plus anterior colporrhaphy (AR) plus any other procedures (MUS/AR), and MUS with any non-AR procedures (MUS+).

RESULTS

Complete datasets were available for 335 patients. Once inadequate tests (low volume voids <200 ml) had been excluded (28% overall), the likelihood of an abnormal second V&R test if the first test was normal was 7.1% overall, but 3.6% for MUS, 11.5% for MUS/AR and 8.6% for MUS+.

CONCLUSION

The findings in the MUS-only group indicate that it is probably safe to discharge patients after one satisfactory V&R test, as long as safety measures such as 'open access' are available so that patients have unhindered readmission if problems arise.

Effects of Transobturator Midurethral Sling Surgery on Sexual Functions: One-Year Follow-Up

AIM

To evaluate sexual functions of women having stress urinary incontinence (SUI) preoperatively and 6 months and 12 months after undergoing a transobturator tape (TOT) ± pelvic organ prolapse (POP) surgery.

METHODS

One hundred-ninety-five women with SUI ± POP were recruited and 150 sexually active women who had clinical ± urodynamic SUI and underwent TOT ± POP surgery were included in this prospective study. Urogynecologic symptoms were evaluated preoperatively, at 6 months, and 12 months by Female Sexual Function Index (FSFI).

RESULTS

One hundred fifty women completed the study. Seventy-four underwent TOT-only and 76 underwent TOT + concomitant surgery. Mean total scores of FSFI were 21.7 ± 7.8, 22 ± 8.7, and 22.1 ± 8 in the preoperative period, postoperative 6, and 12 months, respectively. There was significant improvement in desire and total scores in the TOT-only group, whereas there was no significant difference in the TOT + concomitant surgery group except for significant worsening in the lubrication domain. The frequency of sexual intercourse increased while that of coital incontinence decreased after surgery.

CONCLUSIONS

In our study, TOT was associated with decrease in coital incontinence and significant improvement in desire. In addition, there was significant improvement in FSFI desire and total scores in the TOT-only group, whereas no significant difference was observed in the TOT + concomitant surgery group except for the worsening of lubrication.

Efficacy and safety of a readjustable midurethral sling (Remeex system) for stress urinary incontinence with female voiding dysfunction

Purpose

We investigated the efficacy and safety of a readjustable midurethral sling (Remeex system) for stress urinary incontinence with female voiding dysfunction.

Materials and Methods

From May 2007 to December 2015, 151 women received the Remeex system. We excluded patients who presented with pelvic organ prolapse and/or who missed the regular follow-up. Finally, 102 patients were included in the study, and we divided them into 2 groups: group A (n=74), who did not present with female voiding dysfunction and group B (n=28), who presented with female voiding dysfunction. Female voiding dysfunction was defined as a maximal flow rate≤12 mL/s when the voided volume was ≥150 mL on preoperative uroflowmetry. We retrospectively reviewed the patients' medical records and compared surgical outcomes between groups A and B.

Results

There were no significant differences in subjective surgical outcomes and patient satisfaction between the 2 groups. Postoperative uroflowmetry showed that the maximal flow rate and voided volume decreased and the postvoid residual urine volume increased in both groups, and these changes were not significantly different between groups. The overall complication rate was 21.6% (22 of 102), and the complication rate was not significantly different between the 2 groups according to the modified Clavien-Dindo classification.

Conclusions

The Remeex system is efficacious and safe for stress urinary incontinence with female voiding dysfunction.

Mesh removal after vaginal surgery: what happens in the UK?

INTRODUCTION AND HYPOTHESIS

There is little objective evidence regarding complication rates for mesh procedures outside clinical trials. Current coding poorly collects complications of prolapse and continence surgery using mesh. This survey was designed to identify surgeons performing mesh removal and reporting patterns in the UK.

METHODS

An electronic questionnaire was sent to all members of the Royal College of Obstetricians and Gynaecologists and members of the Section of Female Neurological and Urodynamic Urology of the British Association of Urologists in the UK. The questionnaire aimed to identify the number of procedures performed for mesh complications and whether they were reported to the Medicines and Healthcare products Regulatory Agency (MHRA) and the patterns of referral and treatment RESULTS: Referral to a colleague in the same hospital was common practice (69 %). Only 27 % of respondents stated that they reported all removals to the MHRA. The numbers of surgical procedures were low, with most respondents performing between one and three procedures each year and many not performing any surgery for a specific mesh complication in the previous year.

CONCLUSIONS

Removal of exposed, eroded and/or painful vaginally inserted mesh is performed by many different surgeons in a variety of hospital settings in the UK.

Five years after midurethral sling surgery for stress incontinence: obesity continues to have an impact on outcomes

INTRODUCTION AND HYPOTHESIS

The objective was to evaluate the impact of preoperative body mass index ≥30 on objective and subjective cure rates 5 years after midurethral sling surgery.

METHODS

Secondary analysis of the 5-year results of a randomized clinical trial evaluating tension-free vaginal tape vs transobturator tape surgery. Women (n = 176) were classified as obese or non-obese based on preoperative height and weight. Women self-reported symptoms and quality of life, and underwent standardized physical examinations and pad-testing. Categorical data were analyzed using Chi-squared or Fisher's exact tests, continuous data by Mann-Whitney U test. Primary outcome was objective cure defined as <1 g urine lost on pad-test at 5 years post-surgery. Secondary outcomes were subjective cure of incontinence, urinary urge incontinence symptoms, and quality of life scores.

RESULTS

Non-obese women had a higher rate of objective cure, 87.4 % (n = 83 out of 95) compared with 65.9 % (n = 29 out of 44) in the obese group (P = 0.003, risk difference [RD] 21.5 %, 95 % CI 5.9-37.0 %). Subjectively, non-obese women also reported higher rates of cure, 76.7 % (n = 89 out of 116) compared with 53.6 % (n = 30 out of 56) of obese women (P = 0.002, RD 23.2 %, 95 % CI 8.0-38.3 %). Overall rates of urge incontinence symptoms were similar in the two groups, but rates of bothersome symptoms were higher for obese women (58.9 % vs 42.1 %, P = 0.039, RD 16.8 % 95 % CI 1.1-32.6).

CONCLUSIONS

Five years after surgery, obese women continued to experience lower rates of cure compared with non-obese women.

Learning curves of a resident surgeon performing transobturator tape procedures for stress urinary incontinence

OBJECTIVE

To evaluate the number of procedures necessary for an untrained resident surgeon to learn transobturator tension-free vaginal tape (TVT-O) procedures for treatment of stress urinary incontinence (SUI).

METHODS

A prospective study was performed among patients aged 18-75 years who underwent TVT-O procedures at a center in Rome, Italy, between March 2, 2009, and November 30, 2012. The TVT-O procedure was performed by a right-handed resident surgeon working under the supervision of an expert surgeon. Total and partial operative times were recorded.

RESULTS

Among 18 patients included in analysis, the mean operative time was 22.2minutes (range 7-44). All total operative times fell within the confidence interval after the 10th procedure, with a difference between the mean times recorded in the first nine and the last eight procedures (29.5 vs 13.1minutes; P<0.001). The resident surgeon required nine procedures to learn right tunneling and 13 to learn left tunneling.

CONCLUSION

Ten procedures were required for a resident surgeon to learn TVT-O procedures for SUI.

Five-year follow-up study of Monarc transobturator tape for surgical treatment of primary stress urinary incontinence

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^TM 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. Subjective evaluation included Incontinence Impact Questionnaire (IIQ-7), Urinary Distress Inventory Questionnaire (UDI-6), and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Objective cure was defined as no urinary leakage demonstrable on provocative filling cystometry and/ or 1-h pad test of <2 g. Subjective cure was based on a negative response to question 3 in UDI-6. Paired-samples t test, chi-square, and Fisher exact tests were applied; p < 0.05 was considered significant. The log-rank tests were used to compare event-free survival.

RESULTS

Sixty patients were enrolled, and 56 were evaluated at 5 years postoperatively. The majority were middle aged, postmenopausal, and overweight. Mean operating time was 31.1 ± 8.9 min, intraoperative complications were minor, and median period of follow-up was 80.3 ± 9.6 months. At 5 years of follow-up, objective and subjective cure rates were 89.3 % and 87.5 %, respectively. No mesh-related complications were seen. One patient needed a repeat midurethral sling procedure, and one patient each had bladder and bowel cancer.

CONCLUSION

Monarc TOT was safe and retained its high cure rate in the short- and long-term treatment of stress urinary incontinence.
