    INTRODUCTION AND HYPOTHESIS: Pregnancy and childbirth are risk factors for the development of stress urinary incontinence (SUI). Urinary continence depends on normal urethral support, which is provided by normal levator ani muscle function. Our objective was to compare mean echogenicity and the area of the puborectalis muscle between women with and those without SUI during and after their first pregnancy. METHODS: We examined 280 nulliparous women at a gestational age of 12 weeks, 36 weeks, and 6 months after delivery. They filled out the validated Urogenital Distress Inventory and underwent perineal ultrasounds. SUI was considered present if the woman answered positively to the question "do you experience urine leakage related to physical activity, coughing, or sneezing?" Mean echogenicity of the puborectalis muscle (MEP) and puborectalis muscle area (PMA) were calculated. The MEP and PMA during pregnancy and after delivery in women with and without SUI were compared using independent Student's t test. RESULTS: After delivery the MEP was higher in women with SUI if the pelvic floor was at rest or in contraction, with effect sizes of 0.30 and 0.31 respectively. No difference was found in the area of the puborectalis muscle between women with and those without SUI. CONCLUSIONS: Women with SUI after delivery had a statistically significant higher mean echogenicity of the puborectalis muscle compared with non-SUI women when the pelvic floor was at rest and in contraction; the effect sizes were small. This higher MEP is indicative of a relatively higher intramuscular extracellular matrix component and could represent diminished contractile function

    Contains fulltext : 88897.pdf (publisher's version ) (Closed access)INTRODUCTION AND HYPOTHESIS: The aim of the study was to report anatomic and functional outcome of midline fascial plication under continuous digital transrectal control and to identify predictors of anatomic failure. METHODS: Prospective observational cohort. Anatomic success defined as POP-Q stage or= II underwent midline fascial plication under continuous digital transrectal control. Median follow-up was 14 months (12-35 months), and anatomic success was 80.3% (95% CI 75-86). Independent predictors of failure were posterior compartment POP stage >or= III [OR 8.7 (95% CI 2.7-28.1)] and prior colposuspension [OR 5.6 (95% CI 1.1-27.8)]. Sixty-three percent of patients bothered by obstructed defaecation experienced relief after surgery. CONCLUSIONS: Anatomic and functional outcomes were good. Risk factors for anatomic failure were initial size of posterior POP (stage >or= III) and prior colposuspension.1 juni 201

    Contains fulltext : 96237.pdf (publisher's version ) (Open Access)BACKGROUND: Pelvic organ prolapse (POP) is a condition affecting more than half of the women above age 40. The estimated lifetime risk of needing surgical management for POP is 11%. In patients undergoing POP surgery of the anterior vaginal wall, the re-operation rate is 30%. The recurrence risk is especially high in women with a levator ani defect. Such defect is present if there is a partially or completely detachment of the levator ani from the inferior ramus of the symphysis. Detecting levator ani defects is relevant for counseling, and probably also for treatment. Levator ani defects can be imaged with MRI and also with Translabial 3D ultrasonography of the pelvic floor. The primary aim of this study is to assess the diagnostic accuracy of translabial 3D ultrasonography for diagnosing levator defects in women with POP with Magnetic Resonance Imaging as the reference standard. Secondary goals of this study include quantification of the inter-observer agreement about levator ani defects and determining the association between levator defects and recurrent POP after anterior repair. In addition, the cost-effectiveness of adding translabial ultrasonography to the diagnostic work-up in patients with POP will be estimated in a decision analytic model. METHODS/DESIGN: A multicentre cohort study will be performed in nine Dutch hospitals. 140 consecutive women with a POPQ stage 2 or more anterior vaginal wall prolapse, who are indicated for anterior colporapphy will be included. Patients undergoing additional prolapse procedures will also be included. Prior to surgery, patients will undergo MR imaging and translabial 3D ultrasound examination of the pelvic floor. Patients will be asked to complete validated disease specific quality of life questionnaires before surgery and at six and twelve months after surgery. Pelvic examination will be performed at the same time points. Assuming a sensitivity and specificity of 90% of 3D ultrasound for diagnosing levator defects in a population of 120 women with POP, with a prior probability of levator ani defects of 40%, we will be able to estimate predictive values with good accuracy (i.e. confidence limits of at most 10% below or above the point estimates of positive and negative predictive values).Anticipating 3% unclassifiable diagnostic images because of technical reasons, and a further safety margin of 10% we plan to recruit 140 patients.

    OBJECTIVE: To compare postoperative pain scores and assess efficacy between an adjustable single-incision sling and a standard transobturator sling for stress urinary incontinence (SUI). METHODS: This single-blinded randomized controlled trial involved 156 women with clinically proven SUI. Women were allocated to receive either an adjustable single-incision or a transobturator sling. The primary outcome was postoperative pain score on a visual analog scale. Secondary outcomes were objective and subjective cure rates at 12 months, symptom bother scores, quality of life, and complications. RESULTS: The mean pain score in the first week postoperatively was significantly lower at all time points in the adjustable single-incision sling group compared with the transobturator sling group. Maximum difference in pain score was reported on the evening of the day of surgery; median pain score was 1.0 (interquartile range 2.0) in the adjustable sling group and 3.0 (interquartile range 4.5) in the transobturator sling group (Mann Whitney U test P<.001). There was no statistical difference in analgesic use. The objective cure rates in the adjustable single-incision sling and in the transobturator sling group were 90.8% and 88.6% (P=.760), and the subjective cure rates were 77.2% and 72.9% (P=.577), respectively. No difference in the complication rate was found. CONCLUSION: An adjustable single-incision sling for the treatment of SUI is associated with lower early postoperative pain scores but shows comparable cure rates with a transobturator at 12 months of follow-up.

    OBJECTIVE: To evaluate the association between mean echogenicity of the puborectalis muscle, measured using transperineal ultrasonography, in women during their first pregnancy and the subsequent mode of delivery. METHODS: This is a secondary analysis of a prospective observational study on the association between stress urinary incontinence and levator muscle avulsion after delivery of a first pregnancy. In this study, 280 nulliparous women with singleton pregnancies were examined with transperineal ultrasound examination at 12 and 36 weeks of gestation. Patients were recruited from an obstetrics practice associated with the university medical center in Utrecht, the Netherlands. Mean echogenicity of the puborectalis muscle values were measured at rest, in pelvic floor muscle contraction, and during the Valsalva maneuver. The subsequent mode of delivery was classified into five categories: spontaneous vaginal delivery, instrumental vaginal delivery, elective cesarean delivery, cesarean delivery resulting from nonreassuring fetal status, and cesarean delivery resulting from failure to progress. Mean echogenicity of the puborectalis muscle values according to mode of delivery were compared by analysis of variance and Tukey's post hoc test. RESULTS: Of the 254 women included, 157 had spontaneous vaginal delivery, 47 underwent cesarean delivery (11 elective, 36 emergency), and 45 had vacuum operative vaginal delivery; in five patient files, the mode of delivery was not recorded. Of the analyzed women, those who delivered by cesarean because of failure to progress had a significantly lower mean echogenicity of the puborectalis muscle in pelvic floor contraction at 12 weeks of gestation (mean echogenicity of 116±14) than women who had spontaneous vaginal delivery (132±21; Tukey's post hoc test, P=.03), instrumental vaginal delivery (138±21; P=.004), and cesarean delivery resulting from nonreassuring fetal status (139±20; P=.02). CONCLUSION: Lower mean echogenicity of the puborectalis muscle values in pelvic floor contraction during the first pregnancy at 12 weeks of gestation is associated with subsequent cesarean delivery as a result of failure to progress

No difference was found in the area of the puborectalis muscle between women with and those without SUI. CONCLUSIONS: Women with SUI after delivery had a statistically significant higher mean echogenicity of the puborectalis muscle compared with non-SUI women when the pelvic floor was at rest and in contraction; the effect sizes were small. This higher MEP is indicative of a relatively higher intramuscular extracellular matrix component and could represent diminished contractile function

    INTRODUCTION AND HYPOTHESIS: Internal closure of the urethral sphincter is one of the mechanisms in maintaining continence. Little is known about changes in the urethral sphincter during pregnancy. We designed this study to develop a reliable method to measure the area and mean echogenicity of the midurethra during and after pregnancy and to assess changes over time. METHODS: Two observers independently segmented the urethra as follows: in the sagittal plane, the urethra was positioned vertically, the marker was placed in the middle section of the lumen of the urethra, and eight tomographic US images of 2.5 -mm slices were obtained. The central image was selected, and area and mean echogenicity were calculated automatically. Intra- and interobserver reliability were determined by intraclass correlation coefficients (ICC) and their 95% confidence intervals (CI). Two hundred and eighty women underwent TPUS at 12 weeks and 36 weeks of gestation and 6 months postpartum, and 3D/4D transperineal ultrasound (TPUS) images of 40 pregnant nulliparous women were used for the reliability study. Paired t tests were used to assess changes in echogenicity and area. RESULTS: The ICC for measuring the area was substantial, at 0.77 and for measuring mean echogenicity was almost perfect, at 0.86. In the total study group (n = 280), midurethral area and mean echogenicity were significantly lower 6 months after delivery compared with 12 and 36 weeks of gestation. CONCLUSIONS: Our protocol for measuring area and mean echogenicity of the midurethra is reliable. This study indicates that structural changes in the midurethraoccur during pregnancy

    Objective: The aim of this study was to evaluate a new-generation, single-incision transvaginal mesh (TVM) procedure on anatomical and functional outcomes and complication rates in women with symptomatic cystoceles. Materials and Methods: Sixty-five patients with symptomatic cystoceles (POP-Q stage ≥2) were included in a prospective, multicenter study in the Netherlands to evaluate the TVM procedure using the Nuvia® Anterior Device (Bard Medical, Crawley, UK). The primary endpoint was anatomical cure after 12 months (Pelvic Organ Prolapse Quantification [POP-Q] points Aa and Ba at-2 cm or higher). Secondary endpoints were subjective reduction of pelvic organ prolapse (POP) noted on 3 disease-specific quality-of-life (QoL) questionnaires (Urogenital Distress Inventory [UDI], Incontinence Impact Questionnaire [IIQ], and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire [PISQ-12]); complications; and serious adverse events during and after surgery up to 12 months later. Repeated-measurement analyses were used for POP-Q scores and QoL outcomes. Results: Anterior and apical measurements improved after surgery with anatomical success rates of 70.6% and 60.8% after 6 and 12 months, respectively. Four patients (7.7%) developed vaginal mesh exposure and 2 (3.8%) developed significant pain related to the mesh. Three (5.7%) needed reintervention due to these complications. The apical recurrence rate was 4%, and 2 patients underwent repeat POP surgery. Functional outcomes on UDI, IIQ, and PISQ-12 were satisfactory with significant improvements in QoL reported on all questionnaires. Conclusions: This study demonstrated significant improvement in anatomical and functional outcomes with low complication rates. The single-incision approach to TVM surgery can be a valid option for patients with complex recurrent prolapse

    To assess the diagnostic performance of translabial three-dimensional ultrasonography in detecting major levator ani defects in women with pelvic organ prolapse compared with magnetic resonance imaging (MRI) and to assess the interobserver agreement in detecting levator ani defects with translabial three-dimensional ultrasonography. In a multicenter cohort study, 140 women indicated for primary surgery of pelvic organ prolapse quantification stage II or more cystocele were included. Patients undergoing mesh surgery or concomitant stress incontinence surgery were excluded. All consenting patients underwent translabial three-dimensional ultrasonography and MRI of the pelvic floor before surgery. Two observers (out of a pool of four observers) assessed translabial three-dimensional ultrasound images; two other observers (out a pool of five observers) assessed MRIs for levator ani muscle damage. In case of disagreement, the images were discussed in a consensus meeting. Of the 135 scans, 45 major levator ani defects were detected on ultrasonogram (33.3%) and 32 were confirmed at MRI (23.7%). Of the 41 major levator ani defects detected on MRI, nine were missed at translabial three-dimensional ultrasonogram. Sensitivity was 0.78 (32 of 41) (95% confidence interval [CI] 0.65-0.91) and specificity was 0.86 (81 of 94) (95% CI 0.79-0.93) in detecting major levator ani defects with translabial three-dimensional ultrasonography compared with MRI. There was good agreement scoring levator ani defects on translabial three-dimensional ultrasonography, with a κ of 0.67 (95% CI 0.58-0.76); agreement in recognizing major levator ani defects was moderate, with a κ of 0.53 (95% CI 0.37-0.69). Translabial three-dimensional ultrasonography shows reasonable agreement with MRI in detecting major levator defects. Because of the moderate interobserver agreement, it will be difficult to implement ultrasonography in daily practice. Netherlands Trial Register, www.trialregister.nl, NTR222
