Specific Tips for General Controversies in Sacral Neuromodulation.

The field of Sacral Neuromodulation is continually evolving and still in its infancy. Common dilemmas experienced with this therapy will be discussed in this article, including ways to avoid and manage them. The focus will be on test evaluations performed with either peripheral nerve evaluation (PNE) or staged procedure, the clinical effectiveness and safety of unilateral versus bilateral test stimulation for both the PNE and staged procedures, and best methods to determine the success of the trial phase. We will also discuss how to deal with the problem of declining efficacy of the device over time. The article presents a discussion on future technological innovations to enhance techniques and mode of positioning and use of leads, which along with a refined understanding of how neuromodulation is effective for different problems, will lead to better outcomes.

Midurethral slings versus the standard pubovaginal slings for women with neurogenic stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: Preliminary reports show promising data on tension-free vaginal tape (TVT) in women with lower motor neuron lesion (LMNL) presenting with stress urinary incontinence (SUI). We compared efficacy and safety of TVT to pubovaginal sling (PVS) in treating SUI in women with LMNL. METHODS: This was a pilot, nonrandomized clinical trial evaluating women with SUI associated with pathology at or below S2 spinal segment. Failure was defined as leakage of urine during cough test at 250 ml bladder volume. Primary outcome was time to treatment failure based on positive cough stress test. Other outcomes were Urogenital Distress Inventory Short Form-6 (UDI-6), Incontinence Impact Questionnaire Short Form-7 (IIQ-7) and urodynamics. Regression models were used to adjust for confounders. RESULTS: The study evaluated 40 women: 20 TVT and 20 PVS, and cure rates were 80 and 85 %, respectively. Time to treatment failure in the TVT group was comparable with the PVS group, with an unadjusted hazard ratio (HR) of 2.90 [95 % confidence interval (CI), 0.61-15.42, P = 0.154]. After adjusting for confounders, adjusted HR for treatment failure was 1.04 (95 % CI, 0.12-8.66, likelihood ratio chi-square P = 0.973). Both groups showed significant reductions in UDI-6 and IIQ-7 scores after surgery. One patient had mesh erosion in the TVT group. CONCLUSIONS: TVT is feasible, effective and safe for women with LMNL presenting with SUI, with comparable treatment outcomes to PVS. TVT might be of benefit to women who do not use clean intermittent catheterization (CIC) at baseline.

Arabic validation of the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR).

INTRODUCTION AND HYPOTHESIS: Our aim was to translate then assess the reliability of the culturally adapted Pelvic Organ Prolapse/Incontinence Sexual Function Questionnaire, International Urogynecological Association (IUGA)-Revised (PISQ-IR) to assess sexual health among Arabic-speaking women with pelvic floor disorders. METHODS: PISQ-IR was modified to consider cultural characteristics of the Middle East. The final reliability study included 172 women with urinary incontinence (UI) and/or pelvic organ prolapse (POP). Participants completed the questionnaire twice: at enrollment and 2 weeks later. RESULTS: Among sexually active women, good internal consistency was observed for five of the six scales in the adapted instrument: Global Quality (Cronbach's coefficient α = 0.86), Condition Impact (α = 0.87), Desire (α = 0.82), Condition Specific (α = 0.74), and Partner Related (α = 0.75). Internal consistency was acceptable for the Arousal Orgasm subscale (α = 0.66). However, among not sexually active women, internal consistency was poor (α <0.6) for all four scales. Lin's concordance correlation coefficient measuring agreement between test and retest measurements [Lin's concordance correlation coefficient (CCC); a value of 1 represents perfect agreement] ranged from 0.81 to 0.87 for the not sexually active scales, except for condition impact (CCC = 0.63.) For sexually active women, CCC was typically stronger, ranging from 0.85 to 0.96. CONCLUSIONS: PISQ-IR questionnaire is easy to administer and reliable for assessing sexual function in sexually active Arabic women with POP and UI, but internal consistency is poor for Arabic women not sexually active.

Coital incontinence: relation to detrusor overactivity and stress incontinence.

AIMS: The aim was to assess functional (demographic, clinical, and urodynamic) and anatomical (described by MRI) abnormalities associated with coital incontinence (CI). METHODS: All consecutive sexually active women with urinary incontinence (UI) were invited. Women were asked if they experience urine leakage during sex; and its timing: during penetration (CIAP) versus during orgasm (CIAO). All women were studied with urodynamics. Pelvic MRI was done for selected group of women. MRI examination was done using 1.5 T superconducting magnet, supine, and during two phases: static and dynamic, using multiplanar T2-weighted turbo spin-echo and single short T2-wighted images. RESULTS: Ninety women with UI; 60 had CI while 30 had no CI. Prevalence of CI was significantly higher among women with stress incontinence (SUI) (89.4%) compared to those with detrusor overactivity (DOA) (33.3%); P = 0.000. Factors significantly associated with CI were parity, prolapse, and SUI. Among studied MRI variables, no factor was significantly associated with CI. CI showed significant positive correlation with severity of SUI (r = 0.327, P = 0.05) and significant negative correlation with Abdominal leak point pressure (r = -0.362, P = 0.01). Amplitude of unstable detrusor contraction as measured by urodynamics did not correlate with severity of CI. CONCLUSIONS: CI seems to be in the spectrum of SUI and POP. CI is almost invariably a symptom of SUI with urethral sphincter incompetence, even when it occurs during orgasm. Many women with DOA leak during sex; however, the potential role of associated urethral incompetence should be considered.

Measuring the barriers against seeking consultation for urinary incontinence among Middle Eastern women.

BACKGROUND: Existing questionnaires to assess barriers against consultation for urinary incontinence (UI) are not appropriate for use in the Middle East culture. The aim of this study was to explore barriers against seeking help for UI and introducing a questionnaire that assess these barriers among those women. This is important before proceeding to any educational programs or having interval clinical audits to help incontinent women. METHODS: 1- Screening for UI. Women - aged 20 years and older, attending the outpatient Urology and Gynaecology clinics were invited to participate and interviewed by a research nurse. The UDI-6 was administered to assess the presence and type of UI. Women with UI as their chief complaint were excluded. 2- Interviewing study subjects for possible barriers. Subjects who had UI - as determined by the UDI-6-were first asked an open question "what prevented you from seeking medical consultation for urine leakage?"." They were then asked the proposed questions to assess possible barriers. We developed a preliminary questionnaire based on a review of reasons for not seeking incontinence care from the literature and the response of UI sufferers to the open question in this study. The questionnaire was modified many times to reach this final form. 3- Pilot Study to assess characteristics of the questionnaire. Validity and reliability of the final version of the questionnaire were assessed in a small pilot study including 36 women who completed questionnaire at initial visit and again after 2 weeks. RESULTS: Of the 1231 subjects who agreed to participate in the study, 348 reported having UI. About 80% of incontinent women have never sought medical advice. Factors significantly associated with seeking help were husband encouragement, prayer affection and having severe UI. Common barriers were embarrassment and assuming UI as a normal part of aging. A pilot study included 36 women to assess the psychometric properties of the questionnaire after modifying it. The number of missing or not interpretable responses per item ranged from 2.2% to 8.7%. Internal consistency of the items was good. The test-retest reliability of individual items of the questionnaire was variable, with weighted kappa statistics ranging from 0.32 to 0.94 (median, 0.76, p 0.000). CONCLUSIONS: Preliminary data on our proposed questionnaire show that it is an easy to administer, stable and suits the Middle Eastern culture.

Arabic validation of the Urogenital Distress Inventory and Adapted Incontinence Impact Questionnaires--short forms.

AIMS: The purpose of this study was to adapt the IIQ-7 to suit the Egyptian culture and then to assess validity and reliability of the adapted and translated IIQ-7 and UDI-6. METHODS: IIQ-7 was modified to suit Egyptian culture. Linguistic validation of the two questionnaires was done. Initial test-retest reliability and internal consistency of adapted translated questionnaires were done in a pilot study. The final validity, test-retest reliability and internal consistency study included 204 women with urinary incontinence (UI). Participants completed the two questionnaires at enrollment and after 2 weeks. All participants underwent urodynamics. Baseline urodynamic diagnosis was compared with diagnoses made by questionnaires to assess validity. RESULTS: Test-retest reliability was excellent for both the IIQ-7 and UDI-6. For the UDI-6, the mean difference (SD) between first and second visits was -1.63 (7.0), and the 95% CI for the mean difference was -2.6 and -0.68. The 95% limits of agreement were -15.3 and 12.0. Lin's concordance correlation coefficient (LCCC) (95% CI) for the UDI was 0.89 (0.85 and 0.91). For the IIQ-7, the mean difference (SD) was 0.37 (7.1), and the 95% CI for the mean difference was -0.60 and 1.3. The 95% limits of agreement were -13.5 and 14.2. LCCC (95% CI) for the IIQ was 0.90 (0.87 and 0.92). Internal consistency as assessed using Cronbach's alpha was 0.32 and 0.31 for the UDI-6 and IIQ-7, respectively. Validity assessments indicated that both IIQ and UDI scales can distinguish objective disease states. CONCLUSIONS: UDI-6 and the modified IIQ-7 are easy to administer, test-retest reliable, and valid questionnaires, with relatively low internal consistency.

Patient reported and anatomical outcomes after surgery for pelvic organ prolapse.

AIM: Primary aim was to modify Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ) to assess pelvic organ prolapse (POP) in Arabic Muslim women. Secondary aim was to compare functional and anatomical outcomes of POP repair. METHODS: Questionnaire. A characteristic (prayer) was added to PFIQ. Linguistic validation of questionnaires was then done. Twenty cases were enrolled in a pilot study to test internal consistency and reliability. Subsequent study. Prospective study included women with symptomatic POP >or= stage II. History, examination by POP-Q, and administration of PFDI and PFIQ, were done before and 6 months after surgery. RESULTS: Questionnaire. Internal consistency of added question was good (Cronbach alpha = 0.78). Test-retest reliability of individual PFIQ items was variable. Subsequent Study. Between September 2004 and February 2007, 78 consecutive women were included. Cystocele, rectocele, and no site predominated in 74.4%, 17.9% and 7.7% of cases, respectively. Preoperatively 19.2%, 15.4% and 47.4% reported stress, urge, and mixed incontinence, respectively. Overall and individual urinary symptoms scores improved significantly after surgery. There were significant improvements in individual symptoms of constipation, splint to defecate and losing not well formed stools. Low self-esteem was most negative impact of prolapse on quality of life (QoL) followed by prayer. After surgery 90% of subjects had anatomical cure. After surgery, QoL issues are significantly related to anatomic location of prolapse as determined by POP-Q. CONCLUSIONS: Modified PFIQ and PFDI are suitable to assess POP among Muslim women. Postoperatively, many prolapse-related symptoms and QoL significantly improve after surgery on the short term with an anatomic cure rate of 90%.

Sacral neuromodulation for female pelvic floor disorders.

Objective: To systematically review available studies on the effectiveness and safety of sacral neuromodulation (SNM) in women with various pelvic floor disorders not responding to more conservative treatment, as SNM is indicated in such women. Methods: Data source: We did a systematic review through the PubMed and the Cochrane Library according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement from 1998 to 2018 in English using the keywords 'Sacral Neuromodulation' and 'Sacral Nerve Stimulation'. Study selection: Randomised controlled trials and prospective studies were selected, with a minimum sample size of 20 patients and ≥6 months of follow-up. Results: We identified 19 articles. A ≥50% reduction in symptoms qualifies the patient for a permanent implant. Several advances have been introduced into SNM to decrease the invasiveness of the procedure, including a smaller implantable pulse generator battery (improved comfort) and better localisation of the lead wire (improved outcome). The literature reports success for overactive bladder (OAB) to range between 56% and 68% (up to 80%). We report a 5-year therapeutic success rate of 67%. In our previous studies, 38% of our patients with urge urinary incontinence achieved complete continence at 60-months follow-up, with a therapeutic response rate of 57%. Effectiveness in patients with urinary retention and faecal incontinence are about 70% and 85%, respectively. Effectiveness in interstitial cystitis/bladder pain syndrome appears to be lower compared with OAB. Conclusion: SNM is a safe and effective therapy for women with various pelvic floor disorders. Abbreviations: BONT: botulinum toxin; FDA: USA Food and Drug Administration; FS: Fowler's syndrome; FI: faecal incontinence; IC/BPS: interstitial cystitis/bladder pain syndrome; ICIQ-OABqol: International Consultation on Incontinence Modular Questionnaire-Overactive Bladder Symptoms Quality of Life; INS: implantable neurostimulator; OAB: overactive bladder; PET: positron emission tomography; PNE: peripheral nerve evaluation; PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; PTNM: posterior tibial nerve modulation; PVR: post-void residual urine; QoL: quality of life; RCT: randomised controlled trial; SNM: sacral neuromodulation; (U)UI: (urgency) urinary incontinence.

Update on vesicovaginal fistula: A systematic review.

Objective: To conduct a systematic review of the literature on vesicovaginal fistula (VVF), including reporting on the aetiology, in both developed and underdeveloped countries; diagnosis; intraoperative prevention; and management. Methods: We conducted a systematic review of the literature on VVF through the PubMed and the Cochrane Library according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The search was conducted from 1985 to 2018 in English, using the keywords 'fistula' and 'vesicovaginal fistula'. Prospective studies were preferred; however, retrospective studies and case reports were used when no prospective studies were available. All authors' extracted relevant data related to the proposed review of VVF and carefully examined collected articles. Results: In all, 116 relevant articles were identified and 43 articles were included in this systematic review. The outcome of surgical reconstruction was >90%, but the outcome may be suboptimal in radiotherapy (RT)-induced VVFs. Absolute indications for an abdominal approach included: ureteric involvement, the need for concomitant bladder augmentation, severe vaginal stenosis, and an inability to tolerate the dorsal lithotomy position (e.g. due to muscular spasticity). Typically, it was recommended to wait at least 3 months to allow the inflammatory response to subside before definitive surgery. Early fistula repair can be performed in the absence of infection and in patients who have not received pelvic RT. Conclusion: VVF is rare in developed countries. Surgical treatment is the primary method of repair. The outcome of surgical reconstruction exceeds 90%, but the outcome may be suboptimal in RT-induced VVFs. Abbreviations: PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; RT: radiotherapy; (S)UI: (stress) urinary incontinence; UVF: ureterovaginal fistula; VVF: vesicovaginal fistula.

The satisfaction of patients with refractory idiopathic overactive bladder with onabotulinumtoxinA and augmentation cystoplasty.

OBJECTIVE: To assess the satisfaction of patients with refractory idiopathic overactive bladder (OAB) with two treatment methods, onabotulinumtoxinA (oBTX) and augmentation ileocystoplasty (AC). PATIENTS AND METHODS: This prospective study included patients with refractory idiopathic OAB for >6 months and a urodynamic diagnosis of OAB. Oral pharmacotherapy had failed in all patients. Patients with any suspected neurological disorder were excluded. Before the procedure, patients completed the Urogenital Distress Inventory (UDI-6) and modified Incontinence Impact Questionnaire (IIQ-7), a neurological evaluation, a urodynamic study and their postvoid residual urine volume was measured. Patients were assigned to receive oBTX or AC, depending on patient's preference. Follow-up visits were at 6 weeks and 3 and 6 months after the procedure. The OAB Satisfaction questionnaire (OAB-SAT-q) was used to assess satisfaction after the procedure. RESULTS: In all, 31 patients with refractory OAB were included, 16 in the oBTX group and 15 in the AC group. There was no significant difference between the groups in mean age, baseline OAB symptoms and urodynamic values. There were significant improvements in urinary symptoms (UDI-6) and quality of life (IIQ-7) after both procedures (except in the domain enquiring about difficulty, which significantly worsened after AC). Of the 16 patients, 15/16 and seven of 15 were completely dry after AC and oBTX, respectively. The overall and individual scores of the OAB-SAT-q were significantly higher among patients treated with AC than with oBTX. The incidence of the de novo need to use clean intermittent catheterisation after oBTX and AC was two of 16 and four of 15, respectively. CONCLUSIONS: Both procedures are effective in improving the symptoms of OAB and of quality of life, but patients were more satisfied with AC than oBTX therapy.

The prevalence and risk factors of urinary incontinence and its influence on the quality of life among Egyptian women.

AIMS: The exact magnitude of the problem of urinary incontinence (UI) in Egypt is not yet reported. We studied the prevalence and potential risk factors associated with UI among a group of Egyptian women as taken from a representative sample from the population. DESIGN: A cross-sectional, community-based study. SETTING: Assiut, Upper Egypt, Egypt. PARTICIPANTS: women, aged 20 years and older, selected randomly from the population. MEASUREMENTS: PARTICIPANTS completed a previously validated questionnaire; Urogenital Distress Inventory-short form (UDI-6). RESULTS: A total of 1,652 women were included. The prevalence of UI among our study subjects is 54.8%. Aging, low educational level, menopause, higher parity (>3), vaginal delivery, and previous multiple abortions (>3) were found to be significantly associated with UI. The prevalence of urge, stress and mixed incontinence, mutually exclusive of each other, was 15%, 14.8%, and 25%, respectively. The prevalence of severe incontinence is 8.4%. Regarding the quality of life, the most distressing issues for sufferers were their inability to pray (90%). CONCLUSIONS: UI is quite common in Egypt and prevalence rates are higher when compared to other reports.
