Clinical efficacy of tension-free vaginal tape-ischiopubic ramus versus transobturator tension-free vaginal tape in the management of female stress urinary incontinence.

BACKGROUND: Stress urinary incontinence (SUI), a prevalent condition among middle-aged and elderly women in China, is characterized by the involuntary leakage of urine during instances of increased abdominal pressure [1]. Although SUI is not life-threatening, it substantially impacts patients' physical and psychological well-being, impairs their social interactions, and diminishes their overall quality of life. OBJECTIVE: The aim of this study was to evaluate and compare the clinical efficacy of tension-free vaginal tape-ischiopubic ramus (TVT-IR) and transobturator tension-free vaginal tape (TVT-O) in the treatment of female stress urinary incontinence (SUI). METHODS: A retrospective analysis of clinical data from 83 female SUI patients was conducted, dividing them into a TVT-IR group (n= 41) and a TVT-O group (n= 42) based on the surgical procedures employed. Perioperative indices, surgical efficacy, complications, symptom improvement pre- and post-operation (3 months), urodynamic measurements, and indices related to pelvic floor function and quality of life were compared between the two groups. RESULTS: The TVT-IR group had significantly shorter operative time than the TVT-O group (P< 0.05). Three months after surgery, both groups had significantly lower frequency of incontinence, incontinence score, and number of nocturnal urination, significantly higher Pdet, ALPP, Qmax, and MUCP, significantly higher class I and class II fiber muscle strength and muscle potential, and significantly higher I-QOL scores (P< 0.05). The aforementioned indicators were superior in the TVT-IR group compared to the TVT-O group three months after surgery (P< 0.05). CONCLUSION: Both TVT-IR and TVT-O are effective in treating SUI, with comparable complication rates.

A comparative study of autologous rectus fascia pubovaginal sling surgery and synthetic transobturator vaginal tape procedure in treatment of women with urodynamic stress urinary incontinence.

OBJECTIVE: To compare short term results of autologous rectus fascia pubovaginal sling surgery with synthetic transobturator vaginal tape procedure in treatment of female stress urinary incontinence (SUI) STUDY DESIGN: It was a comparative study on 30 women between 25-65 years of age with urodynamic proven SUI who were randomly allocated to autologous rectus fascia pubovaginal sling surgery (Group I)(15 women) and synthetic transobturator vaginal tape procedure (Group II) (15 women). Preoperative and postoperative ICIQ (International Consultation on Incontinence Questionnaire) score, urodynamic study and serum CRP and IL-6 were done in all cases. RESULTS: The baseline characteristics in terms of age, body mass index (BMI), parity, mean ICIQ score and mean preoperative CRP and IL-6 levels were similar in two groups. Mean operative time was significantly longer (55.60 ± 5.77 vs 25.27 ± 4.32 minutes, p = 0.001) in group I than group II. Mean hospital stay of 7.1 ± 1.2 vs 1.2 ± 0.4 days, mean duration of catheterization 5.8 vs 1.2 day (<0.01) and postoperative urinary retention requiring recathterization were all significantly higher in group I than II. Wound infection was more in group I than in group II (p = 0.01) while groin pain was significantly more in group II (p = 0.01). One patient developed vesicovaginal fistula, while one patient required cutting of tape in group I. Pdet at Q max (Detrusor pressure at peak urine flow) increased significantly in both the groups after surgery. ICIQ score was zero in both the groups indicating 100 % success. Surgical trauma was more in group I as shown by significantly higher CRP levels. CONCLUSION: The success rate of the two groups was similar but, autologous rectus fascia sling surgery took longer, had more complications and urinary retention as compared to transobturator vaginal tape procedure.

Two new mini-slings compared with transobturator tension-free vaginal tape for treatment of stress urinary incontinence: A 1-year follow-up randomized controlled trial.

AIM: The aim of this study was to compare the outcome of two single-incision mini-slings (the Contasure-Needleless [C-NDL] and the endopelvic free anchorage) with the standard midurethral transobturator tension-free vaginal tape (TVT-O) procedure. METHODS: A double blind randomized controlled study was conducted at Ain Shams University Maternity Hospital from August 2014 until July 2015. A total of 209 patients were randomized into three groups. The first group underwent the TVT-O procedure, the second group underwent the endopelvic free anchorage procedure and the third group underwent the C-NDL procedure. Patients were followed up for 12 months in terms of subjective cure, objective cure, and complications rate. RESULTS: After 12 months of follow-up, there were no differences among the three groups in terms of objective cure rate, subjective cure rate, patient satisfaction, or incidence of complications (de novo urge, hemorrhage, infection, and mesh erosion). The C-NDL was associated with a shorter operative time (P < 0.001) and less blood loss (P = 0.021) than the standard TVT-O. CONCLUSION: The new single-incision mini-slings showed similar efficacy and patient acceptance to that of the standard TVT-O for up to 12 months postoperatively with no difference in the complications rate. The C-NDL is associated with shorter operative time and less blood loss.

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.

[Approach and complications associated with suburethral synthetic slings in women: Systematic review and meta-analysis]. / Voies d'abord et complications des bandelettes sous-urétrales synthétiques chez la femme : revue systématique de la littérature et méta-analyse.

INTRODUCTION: We aim to assess the complications associated with different approaches used in female suburethral sling surgery. METHOD: We performed a research on Medline using the following keywords: "suburethral slings", "complications", "safety" and "randomized". Only randomized clinical trials including women and reporting intra- and postoperative complications associated with the retropubic (RP) approach; TOT and/or TVT-O were included. The meta-analysis was conducted using the Review Manager (RevMan 5.3) software delivered by the "Cochrane Library". RESULTS: Out of 176 articles, 23 were included in synthesis. Risks of bladder perforation during surgery (60/1482 vs 5/1479; OR=6.44; 95% CI [3.32-12.50]) and postoperative urinary retention (48/1160 vs 24/1159; OR=1.93; 95% CI [1.26-3.12]) were significantly higher with the RP approach, when compared with the transobturator (TO) approach (TOT or TVT-O). Conversely, the risk of prolonged postoperative pain was significantly lower after RP approach, when compared with TO approach (24/1156 vs 69/1149; OR=0.36; 95% CI [0.23-0.56]). Risks of intraoperative urethral injury, postoperative erosion and de novo overactive bladder were comparable between the two approaches. Data regarding the comparison between TOT and TVT-O were scarce and did not allow us to conclude about complications associated with. CONCLUSION: The RP approach was associated with a significant risk of bladder perforation and postoperative urinary retention. The TO approach was associated with a higher risk of prolonged postoperative pain.

Evaluation of transobturator tension-free vaginal tapes in the surgical management of mixed urinary incontinence: 3-year outcomes of a randomized controlled trial.

PURPOSE: We evaluate the clinical effectiveness of transobturator tension-free vaginal tape procedures in the surgical management of mixed urinary incontinence in women at 3-year followup. MATERIALS AND METHODS: In this secondary analysis of a prospective, single-blind, randomized controlled trial 83 of 341 women (24%) with mixed urinary incontinence were randomized to undergo an outside-in (Aris® transobturator sling system 42) or inside-out (TVT™-O 41) transobturator tension-free vaginal tape procedure. Patients were contacted by postal questionnaire at a minimum of 3 years postoperatively. The primary outcome was the patient reported success rate, defined as very much improved/much improved on the PGI-I (Patient Global Impression of Improvement). Secondary outcomes included improvement in quality of life, impact on preoperative urgency/urgency incontinence and repeat surgical treatment for stress urinary incontinence. Outcomes at 3 years were compared between groups (outside-in vs inside-out) and to 1-year outcomes. Analysis was performed using SPSS® version 20 with significance levels set at p = 0.05. RESULTS: A total of 66 women with mixed urinary incontinence completed the 3-year followup (outside-in 35 vs inside-out 31). In each group 2 women underwent further continence surgery. The patient reported success rate was 73.8% with no significant differences between the groups (OR 1.035, 95% CI 0.342-3.134, p = 0.951). Overall 34 (50.1%) and 26 women (56.5%) reported cure of preoperative urgency and urgency incontinence, respectively, and 52 women (86.7%) had a clinically significant improvement in quality of life (18 points or more in total KHQ [King's Health Questionnaire] score) compared to baseline. CONCLUSIONS: Transobturator tape procedures are associated with a good (73.8%) patient reported success rate at a minimum of 3 years of followup in the surgical management of mixed urinary incontinence in women with predominant stress urinary incontinence symptoms. Nearly half of the women reported cure of urgency/urgency incontinence.
