Levator Ani Avulsion in Ultrasound Increases Recurrence in Sacrospinous Fixation.

IMPORTANCE: Pelvic floor translabial ultrasound (TLUS) can identify levator ani muscle (LAM) avulsion and ballooning, which some studies have shown to be possible risk factors for prolapse recurrence. Our group uses TLUS to counsel patients preoperatively. If any of these risk factors exist, we offer sacrocolpopexy over vaginal repair. However, some patients, even though they have these possible risk factors, prefer to undergo vaginal surgery. OBJECTIVE: The objective of this study was to determine if TLUS LAM avulsion and/or ballooning are risk factors for composite outcome recurrence in patients undergoing sacrospinous ligament fixation for pelvic organ prolapse. STUDY DESIGN: This was a retrospective observational study. All patients with vaginal apical repair with sacrospinous ligament fixation with preoperative TLUS were included. Demographics, clinical characteristics, and follow-up were analyzed. Multivariable logistic regression analysis was performed for composite outcome that included TLUS risk factors, age, Pelvic Organ Prolapse Quantification System measurements and stage, and variables with P < 0.1 in the univariate analysis. RESULTS: Eighty-two patients were included. All patients had symptomatic vaginal bulge; 65.4% had stage III prolapse. Concomitant hysterectomy was performed in 54.3%. Median follow-up was 20 months (interquartile range, 8-35 months); 19.8% had LAM avulsion, and 43.2% had ballooning. Anatomic recurrence rate was 23.5%, symptomatic was 22.2%, and reoperation was 1.2%. The composite recurrence rate was 29.6%. In the multivariable logistic regression analysis, unilateral/bilateral avulsion in TLUS was found to be a significant risk factor for composite outcome with an odds ratio of 4.33 (confidence interval, 1.219-15.398; P = 0.023). CONCLUSIONS: Composite outcome of recurrence in our study was 29.6%. Avulsion on TLUS increased the risk of recurrence of pelvic organ prolapse by fourfold.

Trastornos sensitivos genitales y maltrato psicológico en la relación de pareja: una revisión bibliográfica / Sensitive genital disorders and psychological abuse in the couple relationship: a bibliographic review

INTRODUCCIÓN: Los trastornos sensitivos genitales y su relación con el maltrato psicológico en la pareja es un tema poco tratado en la literatura y, sin embargo, presente en la entrevista médica y psicológica. Aplica para aquellos casos en que no se aprecia alteración en la exploración física suficiente como para atribuirlo a causas orgánicas. OBJETIVO: Recopilar e integrar diferentes visiones acerca del síntoma de insensibilidad genital durante las relaciones sexuales, definir si este síntoma corresponde a una disfunción sexual e indagar sobre su relación con la violencia psicológica en la relación de pareja. MÉTODO: Revisión bibliográfica. Resultados: Los trastornos sensitivos cuya base orgánica es descartada no corresponderían a una disfunción sexual, sino más bien a una alteración sensorial disociativa como respuesta a una situación de violencia psicológica acompañada de violencia sexual en todos los casos. CONCLUSIONES: La insensibilidad genital es un tema que debe ser considerado al hacer la anamnesis de una paciente, para así ser derivada a un especialista con la intención de abordarlo de forma interdisciplinaria y, por ende, evaluar y diferenciar los elementos orgánicos y funcionales del síntoma.

INTRODUCTION: Genital sensory disorders and how they relate to psychological abuse in the couple is a topic that is scarcely address in the literature, however present it might be in medical and psychological interviews. It is often found in cases where there is no perceived sufficient alteration in physical examinations in order to attribute it to organic causes. OBJECTIVE: To collect and integrate different views regarding the symptom of genital insensitivity during sexual intercourse, define whether this symptom relates to sexual dysfunction and inquire about its connection with psychological violence in the couple. METHOD: Bibliographic assessment. Results: Sensory disorders, whose organic basis is ruled out, do not relate to sexual dysfunction but rather to a dissociative sensory alteration in response to a situation of psychological violence accompanied, in all cases, by sexual violence. CONCLUSIONS: Genital insensitivity is an issue that must be taken into account at the time of taking the patients medical history. This way, it can be referred to a specialist with the intention of addressing it in an interdisciplinary way and, therefore, evaluate and differentiate the organic and functional elements of the symptom.

5,926 hysterectomies: complications described by Clavien-Dindo classification.

Hysterectomy is the most common major gynaecological surgery. Due to its high volume, the analysis of its results is relevant. The objective of this study was to describe intraoperative complications and reoperations, for both benign and malignant causes, using the Clavien-Dindo classification (approved by local ethics committee, number 100220). Between 2000 and 2019, 5926 elective hysterectomies were performed, of which 90.2% were for benign aetiology and 9.8% for malignant causes. The abdominal route was 52.7%, vaginal 40.1% and laparoscopic 7.2%. Intraoperative complications and reoperations (grade III Clavien-Dindo) were 4% and 2.1%, respectively. Oncological surgery had significantly more intraoperative complications (10% vs. 3.4%) and reoperations (3.6% vs. 1.9%) than benign procedures. Noteworthy, intraoperative complications required a new operation in only 3.4% for malignant and 2.8% for benign surgery. Our data showed the relevance of detecting and rectifying intraoperative complications during surgery, which consequently leads to a lower reoperation rate, minimising postoperative morbidity and mortality for patients.Impact StatementWhat is already known on this subject? The surgical complications of hysterectomy, both intraoperative and postoperative, are extensively described. However, this information is not well systematised, in which elective and emergency surgery are mixed. In addition to the above, there are few documents comparing the results of hysterectomies due to benign versus malignant causes.What the results of this study add? Using the Clavien-Dindo classification, this study adds an organised description of intraoperative complications and reoperations of hysterectomy in the context of elective surgery. In addition, it provides information on the comparison between surgery for benign versus malignant causes, as well as information on intraoperative complications requiring a new operation.What the implications are of these findings for clinical practice and/or further research? These findings provide clear and orderly data about the risks of elective hysterectomy and showed the relevance of detecting and rectifying intraoperative complications during the procedure. This is useful for specialists to preoperatively identify the risks for each hysterectomy group and provide their patients with more detailed information during informed consent.

Incidence of occult uterine sarcoma and other unexpected pathologies in patients having surgery for presumed myomas: A retrospective observational study.

OBJECTIVE: To determine the incidence of occult uterine sarcomas and other unexpected pathologies in patients undergoing hysterectomies or myomectomies with a pre-operative diagnosis of uterine leiomyomas. STUDY DESIGN: Retrospective study. SETTING: Tertiary hospital in Santiago, Chile. POPULATION: 921 women who underwent surgery for presumed myomas. Database analysis of surgical and pathological notes, from January 2007 to December 2017 with a preoperative diagnosis of uterine leiomyoma. MAIN OUTCOME MEASURES: number of patients with uterine sarcoma confirmed on histology. RESULTS: During this period, a total of 921 gynecological surgeries were performed for benign uterine fibroids of which 787 were hysterectomies and 134 were myomectomies. We found four cases of malignant neoplasms (0,43 %). Two were uterine leiomyosarcoma (LMS), one mixed epithelial and mesenchymal tumor, and one case of incidental cervical cancer. This gives an LMS incidence of 1 in 460 and 1 in 921 of mixed epithelial and mesenchymal tumor. There were seven cases of unexpected benign pathology. This included six atypical myomas and one leiomyoblastoma epithelioid myoma. If we combine the malignant and benign cases, we would have an incidence of 1.2 % of unexpected pathology. CONCLUSION: In our series of patients undergoing myomectomies or hysterectomies for presumed myomas the incidence of LMS was 1 in 460. The incidence of any unexpected pathology including benign ones in presumed myomas was 1 in 83 (six atypical myomas, one leiomyoblastoma epithelioid myoma, two LMS, one mixed epithelial and mesenchymal tumor, one incidental cervical cancer).

Prevalence of anal sphincter defects and association with anal incontinence in women scheduled for pelvic organ prolapse surgery.

AIMS: Some women with pelvic organ prolapse (POP) have concomitant symptoms of anal incontinence. Our aim was to assess the prevalence of anal sphincter defects and the association with incontinence in women undergoing POP surgery. METHODS: Cross-sectional study of 200 women scheduled for POP surgery. They answered yes/no and graded any symptoms of fecal and flatal incontinence on a visual analog scale (0-100). 3D/4D transperineal ultrasound was used to assess internal (IAS) and external anal sphincter (EAS) defects. A defect of ≥30° in ≥4 of 6 slices on tomographic imaging was regarded significant. The association between incontinence and sphincter defects was tested with multivariable logistic regression analysis. RESULTS: The prevalence of any sphincter defect was 50/200 (25%). Combined IAS/EAS defect was found in 19/200 (9.5%) women, 8/200 (4.0%) had isolated IAS, and 23/200 (11.5%) had isolated EAS defects. In women with defect and intact IAS, 37% and 11% reported fecal incontinence, respectively, adjusted odds ratio (aOR) 2.3 (95% confidence interval [CI], 0.7-7.0), p = .147 and in women with defect versus intact EAS, 36% and 9% had fecal incontinence, aOR 4.0 (95% CI, 1.5-10.8), p = .005. In women with defect and intact IAS, 85% versus 43% reported flatal incontinence, aOR 5.2 (95% CI, 1.6-17.2), p = .007 and in women with defect versus intact EAS, 71% versus 43% had flatal incontinence, aOR 1.9 (95% CI, 0.8-4.5), p = .131. CONCLUSIONS: One of four women scheduled for POP surgery had an anal sphincter defect. EAS defects were associated with fecal incontinence and IAS defects were strongly associated with flatal incontinence.

Levator ani muscle injury and risk for urinary and fecal incontinence in parous women from a normal population, a cross-sectional study.

AIMS: To study possible associations between levator ani muscle (LAM) injury and urinary incontinence (UI) and fecal incontinence (FI) and possible associations between bladder neck descent (BND), urethral funneling, and UI. METHODS: A cross-sectional study of 608 women with first delivery in 1990 to 1997 assessed in 2013 to 2014. The Urinary Distress Inventory (UDI-6) and Colorectal Anal Distress Inventory (CRADI-8) were used to quantify symptoms (range, 0-100). The proportion of women with UI and FI was calculated. LAM injury, BND ≥25 mm, and funneling were diagnosed with transperineal ultrasound. Women with LAM injury, BND, and urethral funneling were compared to those without, using the Mann-Whitney U test (symptom scores) and multiple logistic regression analysis (UI and FI). RESULTS: Four-hundred ninety-three (81%) women had intact LAM and 113 (19%) had LAM injury. They had similar median (range) UDI-6 score 8.3 (0-75) vs 4.2 (0-62.5), P = .35, and CRADI-8 score 6.3 (0-78.1) vs 6.3 (0-62.5), P = .90. Three hundred eleven out of six hundred (52%) women had UI and 65 of 594 (11%) had FI. This was similar for women with intact vs injured LAM; UI 53% vs 49%, P = .67; FI 11% vs 12%, P = .44 and with and without BND; stress UI 42% vs 42%, P = .93; urge UI 29% vs 35%, P = .34. Stress UI was more common in women with urethral funneling (50% vs 40%), odds ratio 1.56 (95% confidence interval: 1.03-2.37), P = .04. CONCLUSION: We found no associations between LAM injury and symptoms of UI and FI 15 to 24 years after the first delivery, but urethral funneling was associated with stress UI.

Atraumatic normal vaginal delivery: how many women get what they want?

BACKGROUND: Trauma to the perineum, levator ani complex, and anal sphincter is common during vaginal childbirth, but often clinically underdiagnosed, and many women are unaware of the potential for long-term damage. OBJECTIVE: In this study we use transperineal ultrasound to identify how many women will achieve a normal vaginal delivery without substantial damage to the levator ani or anal sphincter muscles, and to create a model to predict patient characteristics associated with successful atraumatic normal vaginal delivery. STUDY DESIGN: This is a retrospective, secondary analysis of data sets gathered in the context of an interventional perinatal imaging study. A total of 660 primiparas, carrying an uncomplicated singleton pregnancy, underwent an antepartum and postpartum interview, vaginal exam (Pelvic Organ Prolapse Quantification), and 4-dimensional translabial ultrasound. Ultrasound data were analyzed for levator trauma and/or overdistention and residual sphincter defects. Postprocessing analysis of ultrasound volumes was performed blinded against clinical data and analyzed against obstetric data retrieved from the local maternity database. Levator avulsion was diagnosed if the muscle insertion at the inferior pubic ramus at the plane of minimal hiatal dimensions and within 5 mm above this plane on tomographic ultrasound imaging was abnormal, ie the muscle was disconnected from the inferior pubic ramus. Hiatal overdistensibility (microtrauma) was diagnosed if there was a peripartum increase in hiatal area on Valsalva by >20% with the resultant area ≥25 cm2. A sphincter defect was diagnosed if a gap of >30 degrees was seen in ≥4 of 6 tomographic ultrasound imaging slices bracketing the external anal sphincter. Two models were tested: a first model that defines severe pelvic floor trauma as either obstetric anal sphincter injury or levator avulsion, and a second, more conservative model, that also included microtrauma. RESULTS: A total of 504/660 women (76%) returned for postpartum follow-up as described previously. In all, 21 patients were excluded due to inadequate data or intercurrent pregnancy, leaving 483 women for analysis. Model 1 defined nontraumatic vaginal delivery as excluding operative delivery, obstetric anal sphincter injuries, and sonographic evidence of levator avulsion or residual sphincter defect. Model 2 also excluded microtrauma. Of 483 women, 112 (23%) had a cesarean delivery, 103 (21%) had an operative vaginal delivery, and 17 (4%) had a third-/fourth-degree tear, leaving 251 women who could be said to have had a normal vaginal delivery. On ultrasound, in model 1, 27 women (6%) had an avulsion and 31 (6%) had a residual defect, leaving 193/483 (40%) who met the criteria for atraumatic normal vaginal delivery. In model 2, an additional 33 women (7%) had microtrauma, leaving only 160/483 (33%) women who met the criteria for atraumatic normal vaginal delivery. On multivariate analysis, younger age and earlier gestation at time of delivery remained highly significant as predictors of atraumatic normal vaginal delivery in both models, with increased hiatal area on Valsalva also significant in model 2 (all P ≤ .035). CONCLUSION: The prevalence of significant pelvic floor trauma after vaginal child birth is much higher than generally assumed. Rates of obstetric anal sphincter injury are often underestimated and levator avulsion is not included as a consequence of vaginal birth in most obstetric text books. In this study less than half (33-40%) of primiparous women achieved an atraumatic normal vaginal delivery.

Can pelvic floor trauma be predicted antenatally?

INTRODUCTION: Levator trauma is a risk factor for the development of pelvic organ prolapse. We aimed to identify antenatal predictors for significant damage to the levator ani muscle during a first vaginal delivery. MATERIAL AND METHODS: A retrospective observational study utilizing data from two studies with identical inclusion criteria and assessment protocols between 2005 and 2014. A total of 1148 primiparae with an uncomplicated singleton pregnancy were recruited and assessed with translabial ultrasound at 36 weeks antepartum and 871 (76%) returned for reassessment 3-6 months postpartum. The ultrasound data of vaginally parous women were analyzed for levator avulsion and microtrauma. The former was diagnosed if the muscle insertion at the inferior pubic ramus in the plane of minimal hiatal dimensions and within 5 mm above were abnormal on tomographic ultrasound imaging. Microtrauma was diagnosed in women with an intact levator and if there was a postpartum increase in hiatal area on Valsalva by >20% with the resultant area ≥25 cm2 . RESULTS: The complete datasets of 844 women were analyzed. Among them, 609 delivered vaginally: by normal vaginal delivery in 452 (54%), a vacuum birth in 102 (12%) and a forceps delivery in 55 (6%). Levator avulsion was diagnosed in 98 and microtrauma in 97. On multivariate analysis, increasing maternal age, lower body mass index and lower bladder neck descent were associated with avulsion. Increased bladder neck descent and a family history of cesarean section (CS) were associcated with microtrauma. CONCLUSIONS: Maternal age, body mass index, bladder neck descent and family history of CS are antenatal predictors for levator trauma.

Intrapartum predictors of maternal levator ani injury.

INTRODUCTION: Damage to the pelvic floor during vaginal childbirth is common, and may take the form of levator avulsion or irreversible overdistension of the levator hiatus (microtrauma). Such trauma is a major risk factor for pelvic organ prolapse later in life. In this study we aimed to identify intrapartum risk factors for levator trauma. MATERIAL AND METHODS: This is a retrospective analysis of data obtained in two perinatal studies on primiparous women. Between 2005 and 2014, 1148 women carrying an uncomplicated singleton pregnancy in the late third trimester were seen for 4D pelvic floor ultrasound and an interview. They were invited for a repeat assessment at three months postpartum. RESULTS: Of 1148 women, 871 (76%) returned for assessment at a mean of five months postpartum. The datasets of 844 women were analyzed due to missing data or concurrent pregnancy in 27. In all, 452 (54%) had a normal vaginal delivery, 102 (12%) a vacuum, 55 (6%) a forceps, and 235 (28%) a cesarean section. On multivariate analysis forceps, length of second stage and obstetric anal sphincter tears were significantly associated with levator avulsion. There were no significant predictors identified for irreversible overdistension. CONCLUSIONS: The use of forceps, a prolonged second stage, and obstetric anal sphincter tears were associated with levator avulsion. There were no associated intrapartum predictors for hiatal overdistension.

Predicting levator avulsion from ICS POP-Q findings.

INTRODUCTION AND HYPOTHESIS: Levator avulsion is a common consequence of vaginal childbirth. It is associated with symptomatic female pelvic organ prolapse and is also a predictor of recurrence after surgical correction. Skills and hardware necessary for diagnosis by imaging are, however, not universally available. Diagnosis of avulsion may benefit from an elevated index of suspicion. The aim of this study was to examine the predictive value of the International Continence Society Pelvic Organ Prolapse Quantification (ICS POP-Q) for the diagnosis of levator avulsion by tomographic 4D translabial ultrasound. METHODS: This is a retrospective analysis of data obtained in a tertiary urogynaecological unit. Subjects underwent a standardised interview, POP-Q examination and 4D translabial pelvic floor ultrasound. Avulsion of the puborectalis muscle was diagnosed by tomographic ultrasound imaging. We tested components of the ICS POP-Q associated with symptomatic prolapse and other known predictors of avulsion, including previous prolapse repair and forceps delivery with uni- and multivariate logistic regression. A risk score was constructed for clinical use. RESULTS: The ICS POP-Q components Ba, C, gh and pb were all significantly associated with avulsion on multivariate analysis, along with previous prolapse repair and forceps delivery. A score was assigned for each of these variables and patients were classified as low, moderate or high risk according to total score. The odds of finding an avulsion on ultrasound in patients in the "high risk" group were 12.8 times higher than in the "low risk" group. CONCLUSION: Levator avulsion is associated with ICS POP-Q measures. Together with simple clinical data, it is possible to predict the risk of avulsion using a scoring system. This may be useful in clinical practice by modifying the index of suspicion for the condition.

The prevalence of abnormal posterior compartment anatomy and its association with obstructed defecation symptoms in urogynecological patients.

INTRODUCTION AND HYPOTHESIS: Symptoms of obstructive defecation (OD) are common in women. Transperineal ultrasound (TPUS) has been used for the evaluation of defecatory disorders. The aim of our study was to determine the overall prevalence of anatomical abnormalities of the posterior compartment and their correlations with OD in women seen in a tertiary urogynecology clinic. METHODS: This is a retrospective study on 750 women seen at a tertiary urogynecological unit who had undergone a standardized interview, clinical examination, and 4D TPUS. Univariate and multivariate logistic regression analyses were undertaken to study the association between examination findings and symptoms of OD. This study was approved by the local human research ethics committee (Nepean Blue Mountains Local Health District Human Research Ethics Committee, IRB approval no. 13-16). RESULTS: The datasets of 719 women were analyzed. Mean age was 56.1 (18.4-87.6) years. Ninety-seven patients (13 %) reported fecal incontinence, 190 (26 %) constipation, and 461 (64 %) symptoms of OD. On examination, 405 women (56 %) were diagnosed with significant posterior compartment prolapse (POP-Q ≥ stage 2), which was associated with symptoms of OD (p < 0.0001). On ultrasound, 103 (14 %) patients had an enterocele, 382 (53 %) a true rectocele and 31 (4.3 %) had rectal intussusception. On multivariate analysis true rectocele (p = 0.003) and rectal intussusception (p = 0.004) remained significantly associated with symptoms of OD. CONCLUSION: Both symptoms of OD and anatomical abnormalities of the posterior compartment are highly prevalent in urogynecological patients. Ultrasound findings of a true rectocele and rectal intussusception are significantly associated with obstructed defecation.

Digitation associated with defecation: what does it mean in urogynaecological patients?

INTRODUCTION AND HYPOTHESIS: Obstructed defecation is a common symptom complex in urogynaecological patients, and perineal, vaginal and/or anal digitation may required for defecation. Translabial ultrasound can be used to assess anorectal anatomy, similar to defecation proctography. The aim of the present study was to determine the association between different forms of digitation (vaginal, perineal and anal) and abnormal posterior compartment anatomy. METHODS: A total of 271 patients were analysed in a retrospective study utilising archived ultrasound volume datasets. Symptoms of obstructed defecation (straining at stool, incomplete bowel emptying, perineal, vaginal and anal digitation) were ascertained on interview. Postprocessing of stored 3D/4D translabial ultrasound datasets obtained on maximal Valsalva was used to diagnose descent of the rectal ampulla, rectocoele, enterocoele and rectal intussusception at a later date, blinded to all clinical data. RESULTS: Digitation was reported by 39 % of our population. The position of the rectal ampulla on Valsalva was associated with perineal (p = 0.02) and vaginal (p = 0.02) digitation. The presence of a true rectocoele was significantly associated with perineal (p = 0.04) and anal (p = 0.03) digitation. Rectocoele depth was associated with all three forms of digitation (P = 0.005-0.02). The bother of symptoms of obstructed defecation was strongly associated with digitation (all P < = 0.001), with no appreciable difference in bother among the three forms. CONCLUSION: Digitation is common, and all forms of digitation are associated with abnormal posterior compartment anatomy. It may not be necessary to distinguish between different forms of digitation in clinical practice.

Defect-specific rectocele repair: medium-term anatomical, functional and subjective outcomes.

BACKGROUND: Rectocele is a herniation of the anterior wall of the rectal ampulla through a defect in the rectovaginal septum causing protrusion of the posterior vaginal wall. Common symptoms include symptoms of prolapse and obstructed defecation. AIMS: To describe subjective, anatomical and functional results of defect-specific rectocele repair. MATERIALS AND METHODS: This is an internal audit of 137 women who underwent defect-specific rectocele repair. Pre- and post-operative assessment included a standardised interview, clinical examination and 3D/4D transperineal ultrasound. Outcome measures were symptoms of obstructed defecation, recurrent prolapse symptoms, clinical posterior compartment recurrence and rectocele recurrence on ultrasound. RESULTS: At a mean follow-up of 1.4 years, 117 (85%) of women considered themselves cured or improved. Thirty-four (25%) complained of recurrent prolapse symptoms and 47 (34%) symptoms of obstructed defecation, a significant reduction (P < 0.0001). Clinical recurrence (Bp ≥ -1) was seen in 19 women (14%) and recurrence on ultrasound in 27 (20%). The mean depth of recurrence was 16.6 mm (10.3-25.1). We tested multiple potential predictors of recurrence, including age, BMI, vaginal parity, previous hysterectomy and/or prolapse surgery, follow-up time, pre-operative clinical and ultrasound findings. Only hiatal area on Valsalva (OR 0.95 for sonographic recurrence, P = 0.01) and enterocele (for clinical and sonographic recurrence, OR 4.03, P = 0.01 and OR 2.72, P = 0.02, respectively) reached significance. CONCLUSION: Defect-specific rectocele repair is effective both in restitution of normal anatomy and in resolving prolapse and obstructed defecation symptoms at a mean follow-up of 1.4 years.

Does childbirth play a role in the etiology of rectocele?

INTRODUCTION AND HYPOTHESIS: Rectoceles are common among parous women and they are believed to be due to disruption or distension of the rectovaginal septum as a result of childbirth. However, the etiology of rectocele is likely to be more complex since posterior compartment prolapse does occur in nulliparous women. This study was designed to determine the role of childbearing as an etiological factor in true radiological rectocele. METHODS: This was a secondary analysis of the data from 657 primiparous women recruited as part of a previously reported study and another ongoing prospective study. Women were invited for antenatal and postnatal appointments comprising an interview, clinical examination and translabial ultrasonography. The presence and depth of any rectocele were determined on maximum Valsalva maneuver, as was descent of the rectal ampulla. Potential demographic and obstetric factors as predictors of rectocele development were evaluated using either multiple regression or logistic regression analysis as appropriate. RESULTS: A true rectocele was identified in 4% of women antenatally and in 16% after childbirth (P < 0.001). Mean rectocele depth was 13.5 mm (10 - 23.2 mm). The mean antepartum position of the rectal ampulla on Valsalva maneuver was 4.39 mm above and it was 1.64 mm below the symphysis pubis postpartum (P < 0.0001). De novo appearance of true rectocele was significantly associated with a history of previous <20 weeks pregnancy and fetal birth weight. Body mass index and length of the second stage were associated with rectocele depth increase. CONCLUSIONS: Childbirth seems to play a distinct role in the pathogenesis of rectocele. Both maternal and fetal factors seem to contribute.

Negative urodynamic testing in women with stress incontinence.

INTRODUCTION: A minority of women with a subjective complaint of stress urinary incontinence will have negative urodynamic stress incontinence (USI) findings. AIM: To test clinical and ultrasound measures as predictors of an unexpected absence of USI. We hypothesised that unexpectedly negative USI would be more common in young women with good pelvic floor and urethral function. METHODS: A retrospective study analysing 398 data sets from women attending a urogynaecology clinic for evaluation of lower urinary tract and pelvic floor dysfunction. Clinical, urodynamic and translabial ultrasound data were tested as possible predictors of negative USI findings. RESULTS: Women with unexpectedly negative USI findings were younger, had less anterior compartment prolapse and had a higher maximum urethral pressure. Measures of pelvic floor muscle function were not predictive. CONCLUSIONS: Women with unexpectedly negative USI are younger and have better urethral function, but voluntary pelvic floor muscle function seems unrelated to this phenomenon.

Impact of levator trauma on pelvic floor muscle function.

INTRODUCTION AND HYPOTHESIS: Levator trauma is common after vaginal delivery, either as macrotrauma, i.e., levator avulsion, or microtrauma, i.e., irreversible overdistension of the levator hiatus. The effect of microtrauma on muscle function is unknown. We tested the hypothesis that levator trauma is associated with reduced contractile function of the levator ani. METHODS: Pregnant nulliparous women were recruited and seen before and after childbirth. All underwent an interview, a clinical examination including pelvic floor muscle (PFM) assessment using the Modified Oxford scale (MOS) [as an optional component] and translabial ultrasound. Sonographic and clinical parameters of PFM function were assessed before and after childbirth. RESULTS: Out of 560 women, 446 returned at a median of 5 months after childbirth and 433 were suitable for analysis. There was a significant reduction in all measures of PFM function except for MOS. Change in MOS was associated with delivery mode [analysis of variance (ANOVA) P = 0.006). Forty-seven (15 %) vaginally parous women were diagnosed with levator avulsion, which was associated with a reduction in PFM contractility on sonographic parameters and MOS. However, only clinical assessment reached statistical significance. Sixty-five of 312 (21 %) women were diagnosed with microtrauma. We found no evidence of impairment in PFM contractility on ultrasound, but there was a statistically significant reduction in MOS. CONCLUSIONS: Both levator avulsion (macrotrauma) and irreversible overdistension (microtrauma) are associated with reduced contractile function. This effect is more easily detected by palpation than by sonographic indices of levator function.

Pelvic floor dysfunction--does menopause duration matter?

OBJECTIVE: To explore the effect of menopause and hormone replacement therapy on pelvic organ prolapse and pelvic floor muscle function. METHODS: The records of patients who attended a tertiary urogynaecological center were reviewed retrospectively. A standardised interview included menopausal age, i.e. years since last period or onset of menopausal symptoms, current or previous hormone use. The clinical examination included prolapse assessment (POP-Q) and palpation of the levator ani muscle. 4D transperineal ultrasound, supine and after voiding, was performed in all patients. Volume data sets were analysed for pelvic organ descent and measures of contractility and distensibility of the pelvic floor at a later date, blinded to all clinical data. RESULTS: Of 311 women seen during the inclusion period, 65% were postmenopausal. Current systemic or local hormone use was reported by 7% and 6%, respectively. 163 women (52%) reported prolapse symptoms with a mean bother of 5.7/10. Significant pelvic organ prolapse was found on clinical examination (POP-Q stage≥2) in 77%, and diagnosed on ultrasound in 61%. On multivariate analysis, controlling for calendaric age, parity and levator avulsion, there was no evidence for menopausal age as an independent predictor of any symptom and sign of pelvic organ prolapse and pelvic floor muscle function. Local oestrogen use and past or present hormone replacement therapy had no detectable effect on any pelvic floor parameter. CONCLUSIONS: Hormone deficiency following menopause is unlikely to play a major role in pelvic organ support and levator ani function. Hence, both do not appear to be substantially influenced by local or systemic hormone replacement therapy.
