The prevalence of voiding difficulty after TVT, its impact on quality of life, and related risk factors

Narrow Vagina as a Predictor of Obstructive Voiding Dysfunction after Transobturator Sling Surgery

BACKGROUND

Voiding dysfunction (VD) is a potential complication after female midurethral sling operations.

OBJECTIVES

Our goal was to assess the rate of obstructive VD after -transobturator tension-free tape (TOT) procedures and to find perioperative risk factors (RFs) predicting postoperative voiding problems.

METHODS

We have retrospectively evaluated the perioperative data of 397 women who underwent TOT operations. Significant post-void residual (PVR) (>50 mL) was considered as the primary (objective) end point of the study, the voiding difficulty as the secondary (subjective) 1. First univariate analysis and then multivariate logistic regression were performed, with a 5% significance level.

RESULTS

Significant PVR was present in 51 (12.8%) women; catheterization was needed in 21 (5.3%) and reoperation in 3 (0.8%) cases. Seventy women (17.6%) experienced postoperative voiding difficulty. Narrow vagina (<2 cm), older age >70 years, and preoperative voiding difficulty were independent RFs for significant PVR (odds ratio: 5.07, 2.14, 5.38, respectively, p < 0.05). Preoperative overactive bladder syndrome and previous pelvic organ prolapse surgery were considered independent RFs for postoperative voiding difficulty.

CONCLUSIONS

Older age, narrow vagina, or preoperative voiding difficulty increases the chance for significant postoperative PVR. These patients should be chosen and counseled appropriately.

Predictors of early postoperative voiding dysfunction and other complications following a midurethral sling

BACKGROUND

The rates reported for postoperative urinary retention following midurethral sling procedures are highly variable. Determining which patients have a higher likelihood of failing a voiding trial will help with preoperative counseling prior to a midurethral sling.

OBJECTIVE

The objective of the study was to identify preoperative predictors for failed voiding trial following an isolated midurethral sling.

STUDY DESIGN

A retrospective, multicenter, case-control study was performed by including all isolated midurethral sling procedures performed between Jan. 1, 2010 to June 30, 2015, at 6 academic centers. We collected demographics, medical and surgical histories, voiding symptoms, urodynamic evaluation, and intraoperative data from the medical record. We excluded patients not eligible for attempted voiding trial after surgery (eg, bladder perforation requiring catheterization). Cases failed a postoperative voiding trial and were discharged with an indwelling catheter or taught intermittent self-catheterization; controls passed a voiding trial. We also recorded any adverse events such as urinary tract infection or voiding dysfunction up to 6 weeks after surgery. Bivariate analyses were completed using Mann-Whitney and Pearson χ² tests as appropriate. Multivariable stepwise logistic regression was used to determine predictors of failing a voiding trial.

RESULTS

A total of 464 patients had an isolated sling (70.9% retropubic, 28.4% transobturator, 0.6% single incision); 101 (21.8%) failed the initial voiding trial. At follow-up visits, 90.4% passed a second voiding trial, and 38.5% of the remainder passed on the third attempt. For the bivariate analyses, prior prolapse or incontinence surgery was similar in cases vs controls (31% vs 28%, P = .610) as were age, race, body mass index, and operative time. Significantly more of the cases (32%) than controls (22%) had a Charlson comorbidity index score of 1 or greater (P = .039). Overactive bladder symptoms of urgency, frequency, and urgency incontinence were similar in both groups as was detrusor overactivity in those with a urodynamic evaluation (29% vs 22%, P = .136), but nocturia was reported more in the cases (50% vs 38%, P = .046). Mean (SD) bladder capacity was similar in both groups (406 [148] mL vs 388 [122] mL, P = .542) as was maximum flow rate with uroflowmetry and pressure flow studies. Cases were significantly more likely to have a voiding type other than detrusor contraction: 37% vs 25%, P = .027, odds ratio, 1.79 (95% confidence interval, 1.07-3.00). There was no difference in voiding trial failures between retropubic and transobturator routes (23.1% vs 18.9%, P = .329). Within 6 weeks of surgery, the frequency of urinary tract infection in cases was greater than controls (20% vs 6%, P < .001; odds ratio, 3.51 [95% confidence interval, 1.82-6.75]). After passing a repeat voiding trial, cases were more likely to present with acute urinary retention (10% vs 3%, P = .003; odds ratio, 4.00 [95% confidence interval, 1.61-9.92]). For multivariable analyses, increasing Charlson comorbidity index increased the risk of a voiding trial failure; apart from this, we did not identify other demographic information among the patients who did not undergo urodynamic evaluation that reliably forecasted a voiding trial failure.

CONCLUSION

The majority of women will pass a voiding trial on the first attempt after an isolated midurethral sling. Current medical comorbidities are predictive of a voiding trial failure, whereas other demographic/examination findings are not. Patients failing the initial voiding trial are at an increased risk of postoperative urinary tract infection or developing acute retention after passing a subsequent voiding trial.

Clinical risk factors and urodynamic predictors prior to surgical treatment for stress urinary incontinence: a narrative review

INTRODUCTION AND HYPOTHESIS

Knowledge about clinical risk factors and the value of urodynamic testing is important to optimize treatment strategy and secure true informed consent.

METHODS

We reviewed the relevant literature to clarify the evidence regarding clinical risk factors and the predictive value of urodynamic testing in patients with urinary incontinence, where surgery is considered. Because of the paucity of evidence based on randomized controlled trials, we conducted a narrative review of the published literature.

RESULTS

Clinical risk factors in terms of mixed urinary incontinence, previous incontinence surgery, body mass index (BMI) ≥ 35, age ≥ 75, and presence of diabetes mellitus were significantly related to decreased outcome of incontinence surgery. Furthermore, noninvasive and invasive urodynamic parameters indicating detrusor overactivity, voiding difficulties, low urethral pressure, and bladder-neck immobility were related to poorer outcome of surgery.

CONCLUSIONS

This study summarized the available evidence regarding preoperative clinical risk factors and urodynamic parameters indicating decreased or adverse outcome of surgery, and this report also provides clinical recommendations.

[Stress urinary incontinence treatment using Surgimesh® Sling, evolution on patient quality of life and sexual activity during 12 months follow-up]

INTRODUCTION

Evaluation of quality of life (QOL) and sexual activity after using sub-urethral Surgimesh® Sling for female stress urinary incontinence (SUI).

METHODS

Study with a total duration of 12 months. One hundred and sixty-eight patients presenting a SUI underwent surgery for a Surgimesh® Sling implantation.

RESULTS

QOL was significantly improved on the International Consultation Continence Questionnaire (ICIQ) scale with an increase of the average score from 2.79±1.75 to 8.48±1.7 at 12 months (P<0.05). The percentage of patients undergoing sexual intercourses remains at a high level during the study (76.87% versus 78.33%). The number of patients with pain during sexual intercourse significantly decreased (15% versus 2.1%). The QOL score is significantly better in post-operation conditions (7.84 versus 9.20; P=0.001). In terms of continence at 12 months, 75.6% of women declared recovery and 23.53% observed improvements.

CONCLUSION

SUI correction using Surgimesh® Sling induces a very significant improvement in patients' QOL and sexual activity.

Outcome and complications of retropubic and transobturator midurethral slings translated into surgical therapeutic indices

OBJECTIVE

We sought to determine and compare surgical therapeutic indices (STIs) of the retropubic tension-free vaginal tape (TVT) and 2 kinds of transobturator tape (TOT), Monarc (American Medical Systems, Minneapolis, MN), and tension-free vaginal tape obturator.

STUDY DESIGN

This was a retrospective cohort study. Patients with predominant stress urinary incontinence who underwent retropubic (TVT, n = 257) or TOT (n = 180) procedures were included. STIs for both groups were calculated by dividing cure by complication rate at, respectively, 2 and 12 months.

RESULTS

Two months after surgery the STI was significantly higher after TOT whereas 12 months after surgery results of STIs were equal. The explanation is more durable cure rates and declining long-term side effects after TVT procedures.

CONCLUSION

Both surgical approaches seem to have their own benefits. Based on the STI, the balance between cure rate and complications is on the short term in favor of TOT but on the long term similar for TOT and retropubic TVT.

Female voiding dysfunction: prevalence and common associations

The understanding of voiding dysfunction has been greatly assisted by the current introduction of clear definitions for its diagnosis and for the abnormalities of urine flow rates and postvoid residuals that are its basis. Its prevalence in women with symptoms of pelvic floor dysfunction is up to 40%. Most of the recent research has centered on the associations of voiding dysfunction with age, pelvic organ prolapse, and prior continence surgery. The effects of parity, medications, and pelvic tumors have also been explored.

The benefit of early mobilisation of tension-free vaginal tape in the treatment of post-operative voiding dysfunction

INTRODUCTION AND HYPOTHESIS

The aim of this study was to assess the outcome of early mobilisation of tension-free vaginal tape (TVT) in cases of post-operative voiding dysfunction.

METHODS

Thirty-three consecutive cases of early mobilisation of TVT to treat post-operative voiding dysfunction were analysed retrospectively. In each case, the TVT was mobilised and loosened without dividing it, under general anaesthesia, within 2 weeks after the original procedure.

RESULTS

Voiding function subsequently returned to normal in 29 out of 33 women with no recurrence of original stress incontinence. The four remaining women had the tape divided.

CONCLUSIONS

The study shows that early mobilisation of the TVT allows rapid resolution of post-operative voiding dysfunction without compromising the outcome of the original continence procedure.

Initial experience with a short, tension-free vaginal tape (the tension-free vaginal tape secur system)

OBJECTIVE

The aim of this study is to present our first experience with a novel modification of the tension-free sling idea and to evaluate the safety and efficacy of this new procedure for the treatment of stress urinary incontinence in women.

STUDY DESIGN

Eighty-five women with previously untreated stress urinary incontinence were recruited to participate in a clinical study. The efficacy of this surgical procedure was evaluated perioperatively and 3 months (+/-1 week) after operation--objectively by cough test and subjectively by the questionnaires Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire and the International Consultation on Incontinence Questionnaire-Short Form. All data were processed and statistical analyses performed in statistical environment R, version 2.5.1.

RESULTS

From our results we conclude that there were no perioperative complications, objectively 62% of these patients were completely dry and 25% of patients improved. We observed a higher proportion of vaginal wall erosion (7/85) and urgency de novo (5/85) in the learning period group with respect to the routine period group.

CONCLUSIONS

Our first experience with the tension-free vaginal tape secur system procedure is that it has a low percentage of perioperative complications. The learning curve has to be taken in account with reference to postoperative complications.

Resolution of elevated postvoid residual volumes after correction of severe pelvic organ prolapse

We hypothesized that elevated postvoid residual volume (PVRV) would resolve postoperatively in women with severe pelvic organ prolapse (POP) and investigated risk factors that might hamper its resolution. Retrospectively, we enrolled 57 patients undergoing surgery for severe POP. All patients had preoperative PVRV > or = 100 ml documented by ultrasound and catheterization. Presurgical voiding difficulty, urodynamic and cystoscopic data, and surgical outcome were analyzed. The incidence of postsurgical elevated PVRV was 15.8% and 3.5% was symptomatic. Patients with postsurgical elevated PVRV had larger preoperative residual volume than those with normal postsurgical PVRV (P = 0.037). By multivariable analysis, concomitant anti-incontinence surgery was the single independent predictor of postsurgical elevated PVRV (odds ratio = 5.38, P = 0.031). A majority of patients with severe POP had their elevated PVRV resolved postoperatively. Although concomitant anti-incontinence surgery increased the risk of developing elevated PVRV after repair, most remained asymptomatic.

Tension-free vaginal tape and autologous rectus fascia pubovaginal sling for the treatment of urinary stress incontinence: a medium-term follow-up

OBJECTIVES

To compare two different procedures, tension-free vaginal tape (TVT) and autologous rectus fascia sling, according to their medium-term subjective and objective outcomes and satisfaction rates in the treatment of urinary stress incontinence in women.

SUBJECTS AND METHODS

One hundred women with type II urinary stress incontinence were randomized to be treated with either TVT or autologous rectus fascia sling. They were evaluated by means of a cough-induced stress test, 1-hour pad test, Incontinence Impact Questionnaire (IIQ), and urodynamic study. They were reevaluated postoperatively every 6 months, and the collected data of more than 1 year's follow-up were compared with preoperative assessments.

RESULTS

All patients completed the full 6-month postoperative assessment. However, of the 100 patients, only 61 (25 in the TVT and 36 in the sling group) were followed for more than 1 year. Mean follow-up time was 38.5 and 40 months in the TVT and sling group, respectively. Objective cure was achieved in 22 (88%) of the TVT group and in 30 (83%) of the sling group (p = 0.78) using a cough-induced stress test, and in 76 and 75% of the women in the TVT versus sling group (p = 0.83), respectively, using a 1-hour pad test. Postoperative mean IIQ scores were 44.3 (range 35.5-61.5) and 48.5 (range 38.5-69.7) in the TVT versus sling group (p = 0.46). Five (20%) and 11 (30%) of the TVT and sling group, respectively, reported some changes in the voiding pattern or posture at more than 1 year's follow-up.

CONCLUSION

There is no significant difference between the TVT and autologous rectus fascia sling procedures in the treatment of urinary stress incontinence at medium-term follow-up. There were changes in the voiding pattern for patients in both groups at more than 1 year postoperatively, which were not evident at early follow-up.
