Concomitant surgical correction of occult stress urinary incontinence by TOT in patients with pelvic organ prolapse

Unilateral levator avulsion increases the risk of de novo stress urinary incontinence after cystocele repair

INTRODUCTION

Patients without concurrent baseline stress urinary incontinence (SUI) can develop de novo SUI after transvaginal mesh surgery (TVM) for cystocele repair. Surgeons should be aware of de novo SUI risk factors after TVM.

METHODS

A total of 1124 women who were underwent TVM surgeries were recruited and assessed for eligibility from January 1, 2012 to April 30, 2021. All data related to patients and surgeries was collected, which included general conditions, clinical examination, surgery records, and follow-up results. Patients were divided into three groups according to follow-up results and data were compared with each group. The relative risk (RR) of de novo SUI with levator avulsion was also calculated.

RESULTS

Three hundred thirty-six patients were included in this study. They were divided into no complication group (n = 249), de novo SUI group (n = 68), and other complications group (n = 19). It seemed elder or obese women had a higher risk of de novo SUI after TVM (p < 0.05). In de novo SUI group, incidence of levator avulsion before surgery were higher than the other two groups (p = 0.001). TVM can significantly change a prolapse to point Aa and Ba on POP-Q quantification system (p < 0.05). RR ratios of de novo SUI with unilateral avulsion group is 2.60 (95% confidence interval [CI] 1.39-4.87), and 2.58 (95%CI 0.82-8.15) for bilateral group.

CONCLUSION

Unilateral levator avulsion, instead of bilateral levator avulsion, is a risk factor of de novo SUI after cystocele repair surgery.

International Urogynecology consultation chapter 2 committee 3: the clinical evaluation of pelvic organ prolapse including investigations into associated morbidity/pelvic floor dysfunction

INTRODUCTION AND HYPOTHESIS

This manuscript from Chapter 2 of the International Urogynecology Consultation (IUC) on Pelvic Organ Prolapse (POP) reviews the literature involving the clinical evaluation of a patient with POP and associated bladder and bowel dysfunction.

METHODS

An international group of 11 clinicians performed a search of the literature using pre-specified search MESH terms in PubMed and Embase databases (January 2000 to August 2020). Publications were eliminated if not relevant to the clinical evaluation of patients or did not include clear definitions of POP. The titles and abstracts were reviewed using the Covidence database to determine whether they met the inclusion criteria. The manuscripts were reviewed for suitability using the Specialist Unit for Review Evidence checklists. The data from full-text manuscripts were extracted and then reviewed.

RESULTS

The search strategy found 11,242 abstracts, of which 220 articles were used to inform this narrative review. The main themes of this manuscript were the clinical examination, and the evaluation of comorbid conditions including the urinary tract (LUTS), gastrointestinal tract (GIT), pain, and sexual function. The physical examination of patients with pelvic organ prolapse (POP) should include a reproducible method of describing and quantifying the degree of POP and only the Pelvic Organ Quantification (POP-Q) system or the Simplified Pelvic Organ Prolapse Quantification (S-POP) system have enough reproducibility to be recommended. POP examination should be done with an empty bladder and patients can be supine but should be upright if the prolapse cannot be reproduced. No other parameters of the examination aid in describing and quantifying POP. Post-void residual urine volume >100 ml is commonly used to assess for voiding difficulty. Prolapse reduction can be used to predict the possibility of postoperative persistence of voiding difficulty. There is no benefit of urodynamic testing for assessment of detrusor overactivity as it does not change the management. In women with POP and stress urinary incontinence (SUI), the cough stress test should be performed with a bladder volume of at least 200 ml and with the prolapse reduced either with a speculum or by a pessary. The urodynamic assessment only changes management when SUI and voiding dysfunction co-exist. Demonstration of preoperative occult SUI has a positive predictive value for de novo SUI of 40% but most useful is its absence, which has a negative predictive value of 91%. The routine addition of radiographic or physiological testing of the GIT currently has no additional value for a physical examination. In subjects with GIT symptoms further radiological but not physiological testing appears to aid in diagnosing enteroceles, sigmoidoceles, and intussusception, but there are no data on how this affects outcomes. There were no articles in the search on the evaluation of the co-morbid conditions of pain or sexual dysfunction in women with POP.

CONCLUSIONS

The clinical pelvic examination remains the central tool for evaluation of POP and a system such as the POP-Q or S-POP should be used to describe and quantify. The value of investigation for urinary tract dysfunction was discussed and findings presented. The routine addition of GI radiographic or physiological testing is currently not recommended. There are no data on the role of the routine assessment of pain or sexual function, and this area needs more study. Imaging studies alone cannot replace clinical examination for the assessment of POP.

Concomitant transobturator tape and anterior colporrhaphy versus transobturator subvesical mesh for cystocele-associated stress urinary incontinence

INTRODUCTION AND HYPOTHESIS

Stress urinary incontinence (SUI) and cystocele often occur concomitantly and thus may potentially be treated via a single surgical procedure. This study evaluated the efficacy and safety of concomitant transobturator tape (TOT) with anterior colporrhaphy versus subvesical transobturator mesh (TOM) for cystocele-associated SUI.

METHODS

This prospective, clinical trial included women with cystocele-associated SUI. Patients were randomly allocated into either group I (anterior colporrhaphy with concomitant TOT "in-out" fixation) or group II (implantation of a subvesical four-armed TOM). All patients were followed up at 1, 3, 6, 9, and 12 months postoperatively. Statistical tests were performed to compare the group outcomes based on objective, subjective, and anatomical variables.

RESULTS

There were 81 patients in group I and 83 in group II. Median follow-up duration was 12 months. The demographic data and baseline clinical characteristics of both groups were comparable. There were no significant differences between groups regarding the success rates of SUI and cystocele repair. Groups I and II had similar cure rates of SUI (82.9 and 88.4%, respectively; p = 0.369) and incidences of successful cystocele repair (85.4 and 97.7%, respectively; p = 0.055). No urethral or bladder injuries or mesh erosions were reported. Both groups had comparable postoperative complications, except the greater incidence of micturition difficulty in group I than group II, during the early follow-up (12.2% vs. 0.0%; p = 0.024).

CONCLUSIONS

Transvaginal mesh was not superior to native tissue repair. Anterior colporrhaphy and TOT may be an appropriate alternative to four-armed TOM application for concomitant correction of SUI and cystocele.

[Treatment of Urinary incontinence associated with genital prolapse: Clinical practrice guidelines]

INTRODUCTION

Prolapse and urinary incontinence are frequently associated. Patente (or proven) stress urinary incontinence (SUI) is defined by a leakage of urine that occurs with coughing or Valsalva, in the absence of any prolapse reduction manipulation. Masked urinary incontinence results in leakage of urine occurring during reduction of prolapse during the clinical examination in a patient who does not describe incontinence symptoms at baseline. The purpose of this chapter is to consider on the issue of systematic support or not of urinary incontinence, patent or hidden, during the cure of pelvic organs prolapse by abdominal or vaginal approach.

MATERIAL AND METHODS

This work is based on an systematic review of the literature (PubMed, Medline, Cochrane Library, Cochrane database of systematic reviews, EMBASE) for meta-analyzes, randomized trials, registries, literature reviews, controlled studies and major not controlled studies, published on the subject. Its implementation has followed the methodology of the HAS on the recommendations for clinical practice, with a scientific argument (with the level of evidence, NP) and a recommendation grade (A, B, C, and professional agreement).

RESULTS

In case of patent IUE, concomitant treatment of prolapse and SUI reduces the risk of postoperative SUI. However, the isolated treatment of prolapse can treat up to 30% of preoperative SUI. Concomitant treatment of SUI exposed to a specific overactive bladder and dysuria morbidity. The presence of a hidden IUE represents a risk of postoperative SUI, but there is no clinical or urodynamic test to predict individually the risk of postoperative SUI. Moreover, the isolated treatment of prolapse can treat up to 60% of the masked SUI. Concomitant treatment of the hidden IUE therefore exposes again to overtreatment and a specific overactive bladder and dysuria morbidity.

CONCLUSION

In case of overt or hidden urinary incontinence, concomitant treatment of SUI and prolapse reduces the risk of postoperative SUI but exposes to a specific overactive bladder and dysuria morbidity (NP3). The isolated treatment of prolapse often allows itself to treat preoperative SUI. We can suggest not to treat SUI (whether patent or hidden) at the same time, providing that women are informed of the possibility of 2 stages surgery (Grade C). © 2016 Published by Elsevier Masson SAS.

Occult Stress Urinary Incontinence in Women With Pelvic Organ Prolapse: Is the One Step Surgical Approach a Risky Choice?

OBJECTIVES

Occult stress urinary incontinence (SUI, OSUI) is defined as the demonstration of SUI after pelvic organ prolapse (POP) reduction. The aim of this study was to evaluate the effectiveness and complication rates of the 1-step surgical approach for treating women with POP and OSUI.

METHODS

Retrospective study of women with POP and OSUI who underwent a concomitant prolapse and midurethral sling procedure was conducted. Main outcome measures were absence of postoperative urodynamic stress incontinence (USI) and absence of postoperative SUI at 12 months. Secondary outcome measures included evaluation of objective and subjective parameters related to the lower urinary tract function and assessment of the quality of life.

RESULTS

Of the 244 women, 205 women (84%) attended the 12-month postoperative follow-up visit and were included in the study. Overall, 87.8% (180/205) of the patients had absence of postoperative urodynamic stress incontinence, whereas 95.1% (195/205) did not report postoperative SUI. Evaluation of parameters related to the postoperative lower urinary tract dysfunction showed that (a) 43% of women with preexisting urgency symptoms continued to have urgency, (b) 16.7% of patients presented de novo urgency, (c) de novo detrusor overactivity occurred in 9.3% of patients, and (d) 4.9% of women with preoperative obstructive voiding symptoms continued to have obstructive voiding symptoms after combined surgery. King's Health Questionnaire data analysis showed a statistically significant improvement in all domains.

CONCLUSIONS

This 1-step approach is both safe and effective and could be offered as a valid operative choice for those women who wish or should avoid a repeat surgical procedure for postoperative SUI.

Clinical Guideline for Female Lower Urinary Tract Symptoms

The "Japanese Clinical Guideline for Female Lower Urinary Tract Symptoms," published in Japan in November 2013, contains two algorithms (a primary and a specialized treatment algorithm) that are novel worldwide as they cover female lower urinary tract symptoms other than urinary incontinence. For primary treatment, necessary types of evaluation include querying the patient regarding symptoms and medical history, examining physical findings, and performing urinalysis. The types of evaluations that should be performed for select cases include evaluation with symptom/quality of life (QOL) questionnaires, urination records, residual urine measurement, urine cytology, urine culture, serum creatinine measurement, and ultrasonography. If the main symptoms are voiding/post-voiding, specialized treatment should be considered because multiple conditions may be involved. When storage difficulties are the main symptoms, the patient should be assessed using the primary algorithm. When conditions such as overactive bladder or stress incontinence are diagnosed and treatment is administered, but sufficient improvement is not achieved, the specialized algorithm should be considered. In case of specialized treatment, physiological re-evaluation, urinary tract/pelvic imaging evaluation, and urodynamic testing are conducted for conditions such as refractory overactive bladder and stress incontinence. There are two causes of voiding/post-voiding symptoms: lower urinary tract obstruction and detrusor underactivity. Lower urinary tract obstruction caused by pelvic organ prolapse may be improved by surgery.
