Postpartum sexual function; the importance of the levator ani muscle.

INTRODUCTION AND HYPOTHESIS: Pelvic floor muscle function plays an important role in female sexual functioning. Smaller genital hiatal dimensions have been associated with sexual dysfunction, mainly dyspareunia. On the other hand, trauma of the levator ani muscle sustained during childbirth is associated with increased genital hiatus, which potentially can affect sexual functioning by causing vaginal laxity. This study aims to determine the association between levator hiatal dimensions and female sexual dysfunction after first vaginal delivery. METHODS: This is a secondary analysis of a prospective observational study. Two hundred four women who had a first, spontaneous vaginal delivery at term between 2012 and 2015 were recruited at a minimum of 6 months postpartum. Thirteen pregnant women were excluded. We analyzed the association of total PISQ-12 score, as well as individual sexual complaints (desire, arousal, orgasm and dyspareunia), with levator hiatal dimensions at rest, with maximum Valsalva and during pelvic floor muscle contraction as measured by 4D transperineal ultrasound. Statistical analysis was performed using linear regression analysis and Mann-Whitney U test. RESULTS: One hundred ninety-one women were evaluated at a median of 11 months postpartum. There was no significant association between total PISQ-12 score and levator hiatal dimensions. Looking at individual sexual complaints, women with dyspareunia had significantly smaller levator hiatal area and anterior-posterior diameter on maximum Valsalva. By using multivariate logistic regression analysis however we found dyspareunia was not independently associated with levator hiatal dimensions. CONCLUSIONS: After first vaginal delivery sexual dysfunction is not associated with levator hiatal dimensions as measured by 4D transperineal ultrasound.

Association of levator injury and urogynecological complaints in women after their first vaginal birth with and without mediolateral episiotomy.

BACKGROUND: Pelvic organ prolapse is a common health problem in women and has a negative influence on quality of life. A major cause of pelvic organ prolapse is levator injury. OBJECTIVE: The objective of the study was to evaluate the association of mediolateral episiotomy with levator injury (levator avulsion, ballooning, or combined) and urogynecological complaints. STUDY DESIGN: A prospective observational cohort study was performed in 204 primiparous women with a spontaneous vaginal delivery without anal sphincter tear in a general hospital between 2012 and 2015. One hundred three of these women had had a mediolateral episiotomy. Validated urogynecological questionnaires and transperineal 3-dimensional/4-dimensional ultrasound were completed after delivery. Outcome measures were levator avulsion, ballooning (hiatal area of more than 25 cm2), and urogynecological questionnaire scores. Statistical analysis was performed using univariate and multiple logistic regression analysis. RESULTS: The median time at investigation after vaginal delivery was 13 months (range 6-33). Levator injury (avulsion, ballooning, or combined) was identified in 35 of the 103 women who had undergone mediolateral episiotomy (40.0%) and 33 of the 101 women without episiotomy (32.7%) (P = .69). No differences were found in the incidence of levator avulsion 27 (26.7%) vs 23 (22.8%) (P = .53) or in levator ballooning (20 [19.4%] vs 23 [22.8%] (P = .58) between both groups. There was an association between longer duration of the second stage of labor and the incidence of levator avulsion (odds ratio, 1.24 [95% confidence interval, 1.01-1.52]). Nonocciput anterior fetal position increased the risk of levator ballooning and levator injury (odds ratio, 10.19 [95% confidence interval, 1.89-54.91] and odds ratio, 12.16 [95% confidence interval, 1.41-104.38], respectively). No differences in urogynecological complaints were found. CONCLUSION: Mediolateral episiotomy is not associated with the occurrence of levator injury or urogynecological complaints in women with a spontaneous vaginal delivery who did not obtain an anal sphincter injury. Levator injury was associated with a prolonged second stage of labor and a nonocciput anterior fetal position.

Validation of the Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7) in a Dutch population.

AIMS: The Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7) assess symptom distress and the impact on daily life of urinary incontinence. The UDI-6 has not been validated before in males. Our aim was to validate the UDI-6 and IIQ-7 in Dutch men and women. METHODS: The translation to Dutch followed standardized procedures. We validated the IIQ-7 with and without an additional gender-neutral item (IIQ-SF). Adults with urinary incontinence for at least 3 months, completed the measures at inclusion; 1-week after inclusion to evaluate the test-retest reproducibility; and 6 months after inclusion with the addition of the RAND-36 health transition item to assess responsiveness and interpretability. To assess the discriminate ability, a reference population was enrolled. To assess construct validity, the urodynamic diagnosis was used. RESULTS: Questionnaire data of 160 patients were analyzed. Patients reported more symptoms and bother than the reference population (P < 0.001). The internal consistency was good in the IIQ-SF baseline scores (Cronbach's alphas 0.86-0.92), though moderate in the UDI-6 (Cronbach's alphas 0.44-0.66). Both measures showed good reproducibility at the test-retest (Intraclass Correlations Coefficients 0.75-0.85). Construct was adequate with 75% confirmed hypotheses of urodynamic data with measure scores. The measures were responsive after treatment with smaller measurement errors than the minimal important change. No floor or ceiling effects were observed in baseline data. CONCLUSIONS: The Dutch UDI-6 and IIQ-7 are reliable, valid, and responsive instruments for assessing symptom distress of urinary incontinence and its impact on daily life in both men and women.

The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12): validation of the Dutch version.

OBJECTIVES AND HYPOTHESIS: To establish the reliability and validity of the Dutch version of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) in women with pelvic floor dysfunction. METHODS: The PISQ-12 was translated into Dutch following a standardized translation process. A group of 124 women involved in a heterosexual relationship who had had symptoms of urinary incontinence, fecal incontinence and/or pelvic organ prolapse for at least 3 months were eligible for inclusion. A reference group was used for assessment of discriminative ability. Data were analyzed for internal consistency, reproducibility, construct validity, responsiveness, and interpretability. An alteration was made to item 12 and was corrected for during the analysis. RESULTS: The patient group comprised 70 of the 124 eligible women, and the reference group comprised 208 women from a panel representative of the Dutch female population. The Dutch PISQ-12 showed an adequate internal consistency with a Cronbach's alpha of 0.57 - 0.69, increasing with correction for item 12 to 0.69 - 0.75, for the reference and patient group, respectively. Scores in the patient group were lower (32.6 ± 6.9) than in the reference group (36.3 ± 4.8; p = 0.0001), indicating a lower sexual function in the patient group and good discriminative ability. Reproducibility was excellent with an intraclass correlation coefficient for agreement of 0.93 (0.88 - 0.96). A positive correlation was found with the Short Form-12 Health Survey (SF-12) measure representing good criterion validity. Due to the small number of patients who had received treatment at the 6-month follow-up, no significant responsiveness could be established. CONCLUSIONS: This study showed that the Dutch version of the PISQ-12 has good validity and reliability. The PISQ-12 will enable Dutch physicians to evaluate sexual dysfunction in women with pelvic floor disorders.

Validation of the Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7) in a Dutch population.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to validate the Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7) in Dutch women. METHODS: Patients with pelvic floor dysfunction completed the Dutch questionnaires at (1) inclusion to evaluate internal consistency, (2) 1 week later to assess test-retest reliability, and (3) 6 months later to assess responsiveness and interpretability of change. To assess validity, floor and ceiling effects and construct validity were tested. A population-based sample (reference group) completed the questionnaires once. RESULTS: Data of 111 patients and 283 reference group participants were analyzed. Internal consistency of baseline scores in patient and reference groups was moderate (Cronbach's alpha 0.52-0.60) to adequate in the PFDI-20 (Cronbach's alpha 0.71-0.84) and adequate in the PFIQ-7 (Cronbach's alpha 0.88-0.94). Both measures presented adequate test-retest reliability (intraclass correlation coefficient 0.79-0.91) and adequate responsiveness (area under the receiver-operating characteristic curve both 0.77). Interpretability was adequate for PFDI-20 and acceptable for PFIQ-7 with a clinically relevant minimally important change of -23 and -29 points, respectively. At baseline, the scales of the PFIQ-7 showed floor effects (44-55 %) in patients, though the PFIQ-7 summary score did not. No ceiling effects were observed. Construct validity was adequate with all predefined hypotheses confirmed regarding subgroup discrimination using pooled patient and reference group baseline data. CONCLUSIONS: For assessing distress and health-related quality of life of pelvic floor dysfunction, the Dutch PFDI-20 and PFIQ-7 are reliable and valid in the general Dutch population, and also responsive and interpretable among tertiary care-seeking women.

Can magnetic resonance imaging at 3.0-Tesla reliably detect patients with endometriosis? Initial results.

AIM: The aim of this study was to determine whether an optimized 3.0-Tesla magnetic resonance imaging (MRI) protocol is sensitive and specific enough to detect patients with endometriosis. MATERIAL AND METHODS: This was a prospective cohort study with consecutive patients. Forty consecutive patients with clinical suspicion of endometriosis underwent 3.0-Tesla MRI, including a T2-weighted high-resolution fast spin echo sequence (spatial resolution=0.75 ×1.2 ×1.5 mm³) and a 3D T1-weighted high-resolution gradient echo sequence (spatial resolution=0.75 ×1.2 × 2.0 mm³). Two radiologists reviewed the dataset with consensus reading. During laparoscopy, which was used as reference standard, all lesions were characterized according to the revised criteria of the American Fertility Society. Patient-level and region-level sensitivities and specificities and lesion-level sensitivities were calculated. RESULTS: Patient-level sensitivity was 42% for stage I (5/12) and 100% for stages II, III and IV (25/25). Patient-level specificity for all stages was 100% (3/3). The region-level sensitivity and specificity was 63% and 97%, respectively. The sensitivity per lesion was 61% (90% for deep lesions, 48% for superficial lesions and 100% for endometriomata). The detection rate of obliteration of the cul-the-sac was 100% (10/10) with no false positive findings. The interreader agreement was substantial to perfect (kappa=1 per patient, 0.65 per lesion and 0.71 for obliteration of the cul-the-sac). CONCLUSIONS: An optimized 3.0-Tesla MRI protocol is accurate in detecting stage II to stage IV endometriosis.

Detection of anal sphincter defects in female patients with fecal incontinence: a comparison of 3-dimensional transperineal ultrasound and 2-dimensional endoanal ultrasound.

BACKGROUND: Endoanal ultrasound is widely used for the detection of external and internal anal sphincter defects in patients with fecal incontinence. Recently, 3-dimensional transperineal ultrasound has been introduced as a noninvasive imaging method for the detection of these sphincter defects. OBJECTIVE: This study was designed to assess agreement between 3-dimensional transperineal ultrasound and 2-dimensional endoanal ultrasound regarding the detection of anal sphincter defects in women with fecal incontinence. DESIGN: This study was designed as a prospective observational study. SETTINGS: The study took place in a university hospital. PATIENTS: Between October 2008 and June 2009, all women with concerns of fecal incontinence underwent 2-dimensional endoanal ultrasound as well as 3-dimensional transperineal ultrasound. MAIN OUTCOME MEASURES: The main outcome measures are the presence of external and internal anal sphincter defects. RESULTS: Fifty-five patients were included. External and internal anal sphincter defects were observed with 2-dimensional endoanal ultrasound in 27 (49%) and 15 (27%) patients. Three-dimensional transperineal ultrasound detected an external and internal sphincter defect in 19 (35%) and 16 (29%) patients. The Cohen κ coefficient for the detection of external (κ = 0.63) and internal (κ = 0.78) anal sphincter defects was good. LIMITATIONS: This study's limitations include the absence of a surgical examination as the reference standard in the determination of sphincter defects. CONCLUSION: This study shows good agreement between 3-dimensional transperineal ultrasound and 2-dimensional endoanal ultrasound regarding the detection of anal sphincter defects. Based on these data, 3-dimensional transperineal ultrasound might be considered as a valuable alternative noninvasive investigation method.

MRI evaluation of urethral diverticula and differential diagnosis in symptomatic women.

OBJECTIVE: The purpose of this study was to evaluate the role of MRI in the diagnosis and differential diagnosis of urethral diverticula in symptomatic women. MATERIALS AND METHODS: Women referred for MRI at a single institution because of suspicion of urethral diverticula were included. All MRI examinations were independently evaluated by two radiologists and compared with patients' follow-up data. Sensitivity and specificity of MRI for urethral diverticula were calculated using surgery and clinical confirmation as the reference standards. Image quality of the urethra and periurethral region performed with the endoluminal coil was compared with the pelvic phased-array coil. RESULTS: From a study group of 60 patients (mean age, 44 years), 20 patients (33%) had urethral diverticula and 28 (47%) had an alternative diagnosis, of which 13 (46%) were visualized with MRI. In the remaining 12 patients (20%) no abnormalities were found. For urethral diverticula, MRI had both sensitivity and specificity of 100%. Twenty patients had a total of 27 diverticula; these were mostly locally round (n = 12) with sharp margins (n = 25) and high (n = 19) homogeneous (n = 16) signal intensity on T2-weighted sequences. The ostium of urethral diverticula was identified in 23 diverticula (85%) by both readers. Agreement was 93% with κ = 0.72. Endoluminal coil placement in the vagina showed the best image quality of the urethra and periurethral region. CONCLUSION: Dedicated MRI is an excellent imaging modality for urethral diverticula; furthermore, MRI will show the alternative diagnosis in almost one half of the remaining patients.

Anterior sphincteroplasty for fecal incontinence: is the outcome compromised in patients with associated pelvic floor injury?

INTRODUCTION: It has been shown that vaginal delivery may result not only in sphincter defects, but also in pelvic floor injury. However, the influence of this type of injury on the etiology of fecal incontinence and its treatment is unknown. The present study was aimed to assess the prevalence of pelvic floor injury in patients who underwent anterior sphincteroplasty for the treatment of fecal incontinence and to determine the impact of this type of injury on the outcome of this procedure. METHODS: Women who underwent anterior sphincteroplasty in the past were invited to participate in the present study. With transperineal ultrasound, which has been developed recently, pelvic floor integrity was examined in 70 of 117 patients (60%). Follow-up was obtained from a standardized questionnaire. RESULTS: The median time period between anterior sphincteroplasty and the current assessment was 106 (range, 15-211) months. Pelvic floor injury was diagnosed in 43 patients (61%). Despite the prior sphincteroplasty, an external anal sphincter defect was found in 20 patients (29%). Outcome did not differ, neither between patients with and those without pelvic floor injury, nor between patients with and those without an adequate repair. However, patients with an adequate repair and an intact pelvic floor did have a better outcome than patients with one or both abnormalities. CONCLUSION: The majority of female patients with incontinence who were eligible for anterior sphincteroplasty have concomitant pelvic floor injury. Based on the present study, it seems unlikely that this type of injury itself has an impact on the outcome of anterior sphincteroplasty.

Is sacral neuromodulation for fecal incontinence worthwhile in patients with associated pelvic floor injury?

PURPOSE: It has been shown that vaginal delivery may result in pelvic floor injury. Until now it is unknown whether this type of injury plays a role in the etiology of fecal incontinence and whether it affects the outcome of treatment. The aim of the present study was to assess the prevalence of pelvic floor injury in patients with fecal incontinence who were eligible for sacral neuromodulation and to determine whether sacral neuromodulation is worthwhile in patients with pelvic floor injury. METHODS: All women with fecal incontinence who were eligible for sacral neuromodulation in the past were invited to participate in the present study. With transperineal ultrasound, which has been developed recently, pelvic floor integrity was examined in 46 of the 66 patients (70%). Follow-up was obtained from a standardized questionnaire. RESULTS: Pelvic floor injury was found in 29 of the 46 participants (63%). No differences regarding the efficacy of sacral neuromodulation were found between patients with and those without pelvic floor injury. Successful test stimulation was obtained in 86% of the patients with pelvic floor injury and in 71% of the patients without pelvic type injury. After implantation of a definitive pulse generator, a successful outcome was found in 84% of the patients with pelvic floor injury and in 75% of the patients with an intact pelvic floor. CONCLUSION: Pelvic floor injury is present in the majority of incontinent patients who were eligible for sacral neuromodulation. This type of injury seems to have no detrimental effect on the treatment outcome.

Prevalence of major levator abnormalities in symptomatic patients with an underactive pelvic floor contraction.

INTRODUCTION AND HYPOTHESIS: Major levator ani abnormalities (LAA) may lead to abnormal pelvic floor muscle contraction (pfmC) and secondarily to stress urinary incontinence (SUI), prolapse, or fecal incontinence (FI). METHODS: A retrospective observational study included 352 symptomatic patients to determine prevalence of LAA in underactive pfmC and the relationship with symptoms. On 2D/3D transperineal ultrasound, PfmC was subjectively assessed as underactive (UpfmC) or normal (NpfmC) and quantified. LAA, defined as a complete avulsion of the pubic bone, was analyzed using tomographic ultrasound imaging. RESULTS: LAA were found in 53.8% of women with UpfmC versus 16.1% in NpfmC (P < 0.001). Patients with UpfmC were less likely to reduce hiatal area on pfmC (mean 7% reduction vs 25% in NpfmC (P < 0.001)). An UpfmC was associated with FI (P = 0.002), not with SUI or prolapse of the anterior and central compartment. CONCLUSION: An underactive pfmC is associated with increased prevalence of LAA and FI.

Endometriosis of the Bartholin gland: a case report and review of the literature.

BACKGROUND: In this case report we present a case of endometriosis in the Bartholin gland without surgery in the perineal area. So far, only five cases concerning endometriosis in the Bartholin gland, which may or may not be an isolated finding, have been reported in the literature. CASE PRESENTATION: A 31-year-old Indo-surinamese woman with primary infertility presented at our out-patient clinic with cyclical vulvar pain. On gynecological examination, a cyst of 1 × 2 cm was found in the right gland of Bartholin. A transvaginal ultrasound revealed normal gynecological anatomy and did not reveal any contributing information. Due to the recurring pain of the cyst, surgery was scheduled. During surgery, the marsupialization of the cyst resulted in drainage of a chocolate-colored fluid. Pathological examination revealed stroma lined with non-typical columnar epithelium with hemosiderin pigments, which confirmed a diagnosis of endometriosis in the Bartholin gland. CONCLUSION: Our findings revealed a case of endometriosis outside the pelvis, without any deep intraperitoneal involvement. So far, only five cases concerning endometriosis in the Bartholin gland, which may or may not be an isolated finding, have been reported in literature.

Which women are most affected by delivery-related changes in pelvic organ mobility?

OBJECTIVE: Vaginal childbirth is a risk factor for female pelvic organ prolapse and stress incontinence. Imaging studies have suggested that vaginal delivery leads to increased anterior vaginal wall mobility. The authors intended to define the relationship between antepartum pelvic organ mobility and delivery-related changes in these parameters. STUDY DESIGN: Prospective observational clinical study conducted on 200 nulliparous women recruited from antenatal clinic. Patients were assessed by translabial ultrasound in late pregnancy and 2-5 months postpartum. RESULTS: Vaginal childbirth resulted in highly significant changes to all parameters used to describe pelvic organ mobility. These alterations were more marked in those women with limited pelvic organ mobility prior to childbirth, and these negative correlations were highly significant (anterior compartment r=-0.519, P<0.0001, central compartment r=-0.539, P<0.0001, posterior compartment r=-0.604, P<0.0001). CONCLUSIONS: Women with little pelvic organ mobility before childbirth appear to be those that show most marked delivery-related changes.

The biology behind fascial defects and the use of implants in pelvic organ prolapse repair.

Implant materials are increasingly being used in an effort to reduce recurrence after prolapse repair with native tissues. Surgeons should be aware of the biology behind both the disease as well as the host response to various implants. We will discuss insights into the biology behind hernia and abdominal fascial defects. Those lessons from "herniology" will, wherever possible, be applied to pelvic organ prolapse (POP) problems. Then we will deal with available animal models, for both the underlying disease and surgical repair. Then we will go over the features of implants and describe how the host responds to implantation. Methodology of such experiments will be briefly explained for the clinician not involved in experimentation. As we discuss the different materials available on the market, we will summarize some results of recent experiments by our group.

Antenatal pelvic organ mobility is associated with delivery mode.

OBJECTIVE: Relaxation of pelvic ligaments may facilitate parturition in certain animal species. Biomechanical properties of pelvic connective tissue may also influence progress of labour in the human female. This study was designed to test whether peripheral joint mobility or pelvic organ mobility as measures of connective tissue biomechanical properties are associated with progress in labour and delivery mode. DESIGN: Prospective clinical observational study. SETTING: Tertiary obstetric service. SAMPLE: 200 nulliparous women recruited in antenatal clinic. METHODS: Translabial ultrasound was used to obtain data on third trimester pelvic organ mobility. Upper limb joint mobility was assessed clinically. MAIN OUTCOME MEASURES: Gestational length, length of first and second stage of labour, delivery mode. RESULTS: Pelvic organ mobility was significantly associated with total length of second stage (P = 0.034 to P = 0.002). This was mainly due to the length of passive, not active second stage. There also was a statistically significant association between delivery mode and pelvic organ descent (P = 0.007 to P = 0.001), with the lowest mobility seen in women who required a Caesarean section in second stage. Joint mobility did not correlate with delivery data. CONCLUSION: Third trimester pelvic organ mobility is associated with duration of second stage and delivery mode.

Pilot study of botulinum toxin type A in the treatment of chronic pelvic pain associated with spasm of the levator ani muscles.

OBJECTIVE: To investigate whether botulinum toxin type A (BOTOX) injected into the levator ani muscles of women with objective pelvic floor muscle spasm decreases pain symptoms and improves quality of life. DESIGN: A prospective cohort study. SETTING: Outpatient clinic in a tertiary referral centre, Sydney, Australia. SAMPLE: Twelve women, aged 18-55 years, with objective pelvic floor muscle hypertonicity and a minimum 2-year history of chronic pelvic pain were recruited. METHODS: All women completed visual analog scale pain assessments; questionnaires relating to bladder and bowel symptoms and quality of life; and specific examinations. Forty units of BOTOX at three different dilutions were given bilaterally into the puborectalis and pubococcygeus muscles under conscious sedation. RESULTS: Median visual analog scale scores were significantly improved for dyspareunia (80 vs 28; P=0.01) and dysmenorrhea (67 vs 28; P=0.03), with non-significant reductions in non-menstrual pelvic pain (64 vs 37) and dyschesia (47 vs 29). Pelvic floor muscles manometry showed a 37% reduction in resting pressure at week 4 and a 25% reduction was maintained at week 12 (P <0.0001). Quality of life scores (EQ-5D and SF-12) were improved from baseline at week 12, but did not reach statistical significance. Sexual activity scores were markedly improved, with a significant reduction in discomfort (4.8 vs 2.2; P=0.02) and improvement in habit (0.2 vs 1.9; P=0.03). These results were not influenced by dilution. CONCLUSION: There is evidence from the present pilot study suggesting that women with pelvic floor muscles hypertonicity and pelvic pain may respond to BOTOX injections into the pelvic floor muscles. Further research into this novel treatment of chronic pelvic pain is strongly recommended.
