Autologous Transobturator Urethral Sling Placement for Female Stress Urinary Incontinence: Short-term Outcomes

Autologous versus synthetic midurethral transobturator sling: A systematic review and meta-analysis of outcomes

INTRODUCTION

There have been concerns around the use of synthetic mesh for stress urinary incontinence (SUI) surgery with a renewed interest in the use of autologous tissues. Recently, an autologous transobturator sling (aTOT) has been described, but the comparative data with synthetic transobturator sling (sTOT) is limited. The objective of this systematic review and meta-analysis was to assess the outcome of aTOT and compare it with sTOT.

METHODS

A systematic search of PubMed, Scopus, and Web of Science databases was performed and all articles available up to December 31, 2023 were screened. Studies reporting on the outcomes of aTOT and those comparing aTOT with sTOT were included. This review was performed as per Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

RESULTS

Eleven studies evaluating 323 patients that met the criteria were included in the final analysis, of which 6 were single arm (155 patients) and 5 were comparative. In single-arm studies, the pooled success rate, defined as negative cough stress test at 12 months follow-up was 96.8%, 3.8% had postoperative urinary retention, 6.1% had graft site-related complications and 7.6% required additional intervention for persistent SUI. The overall complication rate was 20.6% and there were no Clavien III-V complications. aTOT had similar success and complication rates when compared with sTOT but had a significantly longer operative time (weighted mean difference: 22.35 min, p < 0.00001) and superior sexual function outcomes.

CONCLUSIONS

aTOT, at short-term follow-up (12 months), has similar efficacy and complication rates when compared to sTOT. However, given that the data is limited and not of very good quality, and the fact that long-term follow-up is not available, further studies are required to better define the role of aTOT in the management of female patients with SUI.

Enhancing the autologous fascial sling procedure: A novel fixation method for treating stress urinary incontinence in female patients

BACKGROUND

Synthetic mid-urethral sling surgery has long been the standard surgical treatment for stress urinary incontinence (SUI) worldwide. Using an autologous fascial sling is an alternative to reduce adverse events. We evaluated the treatment outcomes of a novel fixation method applied to the autologous transobturator fascial (TOF) sling procedure for female patients with SUI.

METHODS

A retrospective study was conducted between 2017 and 2020, including 33 patients with SUI who underwent mid-urethral TOF sling surgery with the novel fixation method. We used a self-locking feature (V-LOC™) that was fixed to each side of skin layer above the obturator foramen, and the tension of the fascia sling was adjusted by manipulating the V-LOC™ suture. We analyzed all data collected through questionnaires, including Urinary Distress Inventory-Short Form (UDI-6), Incontinence Impact Questionnaire-Short Form (IIQ-7), Overactive Bladder Symptom Score (OABSS), and Clinical Global Impressions of Improvement (CGI-I). Adverse events were also recorded.

RESULTS

This study included 33 female patients aged 39 to 79 (mean 59.76 years). Following the procedure, there was a significant reduction in the total scores of UDI-6, IIQ-7, and OABSS (preoperative 9.73 ± 4.35, 10.21 ± 5.79, 6.06 ± 4.03 and postoperative 3.52 ± 3.41, 0.85 ± 3.67, 3.06 ± 2.90, respectively) ( p < 0.001). Further analysis of each sub-score of the questionnaires revealed significant improvement in certain symptoms. The mean total score of CGI-I was 2.00 ± 0.80. The maximum flow rate was documented for 18 patients, and no significant reduction was observed after the procedure ( p = 0.804). Complications reported included voiding dysfunction in two patients (6.1%), inguinal pain in one patient (3.0%), and mild delayed wound healing in one patient (3.0%).

CONCLUSION

This modified TOF sling surgery with a novel fixation method by V-LOC™ suture offers feasibility and adjustability as its main advantages. Our study demonstrated significant improvements in patient outcomes.

A modified mid-urethral sling technique for stress urinary incontinence: Three-year results of a prospective randomized trial in comparison with original transobturator tape procedure

INTRODUCTION AND HYPOTHESIS

Stress urinary incontinence (SUI) is the most common subtype of urinary incontinence, which causes many social, psychological, and economic problems. Mid-urethral sling (MUS) surgery is popular worldwide for the treatment of SUI. We aimed to define a new modified mid-urethral sling technique (mMUS) in SUI treatment and to compare it with transobturator tape (TOT) surgery in terms of safety and efficiency.

METHODS

A prospective, randomized study was planned with 126 women suffering from SUI. The patients were randomly divided into two groups, TOT and mMUS. In mMUS, the obturator membrane was not perforated. The objective and subjective symptoms, pain, quality-of-life measures, and side effect profiles were assessed in a 3-year follow-up. The visual analogue scale (VAS) was used for postoperative pain assessment. The International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) and Patient Global Impression of Improvement (PGI-I) were used for cure assessment scales.

RESULTS

In total, 96 patients completed 3-year follow-up (TOT, n = 49 and mMUS, n = 47). There was no statistical difference between the procedures in terms of cure rates (87.75% and 87.23%, respectively; p = 0.614). Mean VAS scores at 8 and 24 h postoperatively were significantly higher in the TOT group (p < 0.05). There was no significant difference between the groups in VAS scores after 24 h. There was no significant difference between groups in terms of pad test results, ICIQ, or PGI scores at baseline and 36 months after surgery.

CONCLUSIONS

We showed that the mMUS procedure was as safe and effective as TOT, with less postoperative groin pain and complications.

Comparison of Autologous Rectus Fascia and Synthetic Sling Methods of Transobturator Mid-Urethral Sling in Urinary Stress Incontinence

Objective: This study aims to compare the efficacy and complications between mesh obtained from the autologous rectus fascia and synthetic mesh used in transobturator tape procedure in the surgical treatment of urinary stress incontinence.

Methods: A total of 62 female patients who underwent operation due to urinary stress incontinence were included in the study. From these, 31 patients underwent autologous rectus fascia with mid-urethral sling (Group 1), and the remaining 31 patients underwent the same operation using synthetic multilaminar propylene sling (Group 2). The groups were compared preoperative and postoperative according to results of Urogenital Distress Inventory-Short Form (UDI-6) and Incontinence Impact Questionnaire-Short Form (IIQ-7). Demographic characteristics, surgical features, and complications were also compared between the groups. P < 0.05 values were considered statistically significant.

Results: The mean age was found as 54.74 ± 0.87 in Group 1 and 55.58 ± 0.76 in Group 2. There was no significant difference between the groups in terms of the preoperative and postoperative UDI-6 results ​​(p=0.258, p=0.349). Similarly, the preoperative and postoperative IIQ-7 results did not show a significant difference between the groups (p=0,483, p=0,367). There was also no significant difference in demographic characteristics and complications between the groups. Only the mean operational time was significantly longer in Group 1 (p=0.029).

Conclusion: Transobturator tape procedure with autologous rectus fascia is as effective and safe as synthetic mesh. This procedure provides an inexpensive and consumable option without posing a risk of mesh erosion and with low complication rates.

Long-term postoperative follow-up results of transobturator autologous rectus fascial sling versus transobturator tension-free vaginal tapes for female stress urinary incontinence: Randomized controlled clinical trial

AIMS

To evaluate the outcomes of a new surgical technique for the treatment of stress urinary incontinence (SUI).

METHODS

This randomized study included 132 index patients from January 2017 to May 2021, 60 applied with autologous facia and 60 with transobturator tension-free vaginal tape (TVT-O). The primary endpoint was dryness (negative stress test and 0 pad use per day) and this was assessed at 3, 6, 12, and 24 months. The secondary endpoints were the International Consultation on Incontinence Questionnaire short form (ICIQ-SF) and the urinary incontinence quality of life (QoL) at 3, 6, 12, and 24 months.

RESULTS

The dryness rate at 24 months was 92.4% (49/53) for patients with transobturator autologous rectus fascial sling (TO-AFS) and 94.6% (53/56) for those with TVT-O (p = 0.47). No difference was determined between the TO-AFS and TVT-O groups in respect of the ICIQ-SF and QoL scores at 2 years postoperatively (p = 0.87). There were five postoperative complications in the TO-AFS group (one urinary retention, one hematoma at suprapubic incision line, and three intermittent groin pains) and four in the TVT-O group (four persistent groin pain) (p = 0.98).

CONCLUSIONS

The objective cure rates of the 24-month outcomes of TO-AFS indicate that this novel surgical technique seems to be a highly effective, safe, and feasible procedure for the treatment of SUI, but further studies including long-term follow-up are mandatory to confirm these preliminary data.

"Mesh free" autologous transobturator mid urethral sling placement for predominant stress urinary incontinence: A pilot study

AIMS

To assess the efficacy and safety of autologous mid-urethral sling (MUS) in women with predominant stress urinary incontinence (SUI).

MATERIALS AND METHODS

This prospective cohort study included adult women with predominant SUI seen in our urology clinic between January 2018 and March 2019. Patients with: negative cough stress test, history of prior incontinence surgery, urogenital malignancy, pelvic radiation, neurological disease, body mass index more than 40 kg/m² , the presence of more than Stage I pelvic organ prolapse, active urinary tract infection, maximum flow rate less than 15 ml/sec, postvoid residual urine more than 100 ml, abdominal leak point pressure less than 60 cm of H₂ O, and pregnant women were excluded. Eligible patients underwent a transobturator MUS procedure using rectus fascia as a sling. Before the procedure, patients filled the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptom (ICIQ-FLUTS) and the Female Sexual Function Index (FSFI) questionnaire. Urinary outcomes were assessed at 3- and 12-months while sexual outcomes were assessed at 12-months.

RESULTS

Thirty patients with median age of 44.5 years were included. All patients had a negative cough stress test during follow up. A significant improvement was noted in the ICIQ-FLUTS scale, bother scale, filling and incontinence subscales at 3 and 12 month follow-up. A significant improvement was also noted in the FSFI full scale score and FSFI domains of mean sexual desire, arousal and lubrication at 12 months follow-up. Two patients developed voiding dysfunction requiring urethral dilatation.

CONCLUSION

Autologous transobturator MUS surgery appears to be safe and efficacious in the short term. More research is needed to clarify its role in the surgical management of SUI in women.

Autologous transobturator midurethral sling

OBJECTIVE

The aim of this study is to describe a novel transobturator midurethral sling surgery technique by using rectus abdominis fascia.

MATERIAL AND METHODS

A 54-year-old woman complaining of urinary leakage during effort was diagnosed as pure stress urinary incontinence after detailed questioning, pelvic examination, uroflowmetry and measurement of residual urine volume. She was anxious about complications related to synthetic meshes. However, she was not interested in relatively morbid surgeries such as colposuspension and pubovaginal sling. Autologous transobturator midurethral sling was discussed with the patient. The patient approved the surgery and the surgery was planned. A 5 cm rectus fascia was harvested via suprapubic incision and non-absorbable stay sutures were placed on its' both edges. Anterior vaginal incision together with paravaginal dissection was performed, as in classical transobturator sling surgery. Groin puncture and blind dissection of adipose tissue was performed. C-shaped trocars were inserted, and advanced through groin punctures and brought up to midurethral incision by finger guidance. Stay sutures were transported via C-shaped trocars to the groin puncture in both sides. Graft was positioned on the midurethral part without any tension and stay sutures were tied to create a tissue bridge on obturator membrane. Incisions were closed and vaginal tampon was placed. Patient was discharged at the first postoperative day.

RESULTS

At postoperative third and sixth months, patient was totally dry and did not have any voiding complaints. Small abdominal and vaginal incisions were clean, as well.

CONCLUSION

Autologous transobturator midurethral sling surgery is a safe, effective and feasible surgical option for stress urinary incontinence in the era which mesh-related concerns are rising. Studies with larger volume and long-term follow up periods are needed.

Optimising the tension of an autologous fascia pubovaginal sling to minimize retentive complications

AIM

To determine the optimal degree of pubovaginal slings (PVS) tension, measured by lax sling dimensions to minimize the risk of urinary retention.

METHODS

This prospective study analyzed female patients undergoing PVS for stress urinary incontinence (SUI) by two surgeons over 24 months from January 2016. Intra-operative measurements of lax sling dimensions tented over rectus fascia were recorded. Logistic regression was used to analyse the likelihood of urinary retention (more than 3 months of intermittent self-catheterisation (ISC) or surgical revision) for given PVS dimensions. The secondary analysis assessed for an association between PVS measurements and persistent SUI.

RESULTS

Fifty-one patients were recruited with a median age of 53 (34-78) and follow-up of 11 (3-20) months. All but one patient reported improvement of SUI. Ten (19.6%) patients developed postoperative urinary retention. Five (9.8%) resolved after a temporary period of ISC. The other five (9.8%) required ongoing ISC or sling division. A strong association existed between short sling height and prolonged urinary retention (P = 0.00). Receiver operating characteristic (ROC) curve analysis showed a sling height of 40 mm had a sensitivity of 100% and specificity of 51% for retentive complications (area under curve [AUC]  = 0.90). Lax sling height up to 60 mm was not associated with persistent SUI.

CONCLUSIONS

Stretching the sling suspension sutures at least 40 mm above the rectus fascia was associated with a lower risk of urinary retention than less than 40 mm. This simple technique would appear to be worth evaluating in a larger sample. A looser sling did not compromise the cure of SUI at a mean follow-up of 11 months.
