Abstract
AIMS The aim of this retrospective study was to try to find correlations between different diagnoses established by clinical examination, anorectal manometry and MRI-defecography and, the association with psychiatric disorders. METHODS 44 patients (median age 53.81 years) presenting with intestinal motility disorders and who underwent clinical, biological and psychiatric examination, dynamic defecographic-MRI (resting, squeezing, straining, defecation and evacuation phases), anorectal manometry, colonoscopy. MRI was performed using the 1,5 T. RESULTS MRI-defecography revealed the following changes: anismus (16), rectocele (12), pelvic floor dysfunction (6), peritoneocele (2), cervical-cystic-ptosis (1), rectal prolapse (6), and in 1 case the examination was normal. Hypertonic anal sphincter (16) and lack of defecation reflex (12) at anorectal manometry correlated with anismus in all patients at MRI-defecography. Lack of inhibitor anal reflex (6) was associated with rectocele (4), cervix-cysto-ptosis (1) and peritoneocele (2). Anxiety (11), depression (6) and anxiety-depressive disorders (10) were found in 27/44, somatization disorders in 9/44 and no psychiatric changes in 8/44 cases. CONCLUSION As multiparous women are at risk for outlet obstruction constipation, MRI-defecography is suggested in this category. There is good correlation between diagnosis using anorectal manometry and MRI-defecography in patients with terminal constipation and anismus. Lower defecation dysfunction is often associated with psychiatric disorders.

Abstract
BACKGROUND Pelvic organ prolapse (POP) is clinically assessed and staged commonly by the pelvic organ prolapse quantification (POP-Q) system. Dynamic magnetic resonance imaging (MRI) of the pelvic floor is an emerging modality for anatomical and functional assessment of the pelvic floor and staging of POP. The purpose of this study was to correlate the dynamic MRI findings with POP-Q examination for the staging of POP in each pelvic compartment by comparing various anatomic points. METHODS A prospective observational study of the comparative cross-sectional design was conducted among patients who underwent MRI of the pelvic floor and POP-Q at our institute. A total of 50 patients were included. Anatomical landmarks in the three compartments were analyzed in relation to standard reference lines on dynamic MRI and compared with POP-Q measurements. RESULTS Most of our patients had multicompartment disease (70%). When compared to POP-Q, MRI has a strong correlation for quantification of anterior (0.723) and middle (0.525) compartments and a weak correlation (0.232) for posterior compartment prolapse. CONCLUSION POP-Q examination is based on the various points within the vaginal canal, and all the points do not represent a true anatomic landmark. MRI, on the other hand, is based on a true anatomical plane and gives detailed information about various structures in all three compartments. Thus, MRI also helps bridge the gap between various referring specialties in treating pelvic floor disorders.

Abstract
INTRODUCTION AND HYPOTHESIS We aimed to develop a deep learning-based multi-label classification model to simultaneously diagnose three types of pelvic organ prolapse using stress magnetic resonance imaging (MRI). METHODS Our dataset consisted of 213 midsagittal labeled MR images at maximum Valsalva. For each MR image, the two endpoints of the sacrococcygeal inferior-pubic point line were auto-localized. Based on this line, a region of interest was automatically selected as input to a modified deep learning model, ResNet-50, for diagnosis. An unlabeled MRI dataset, a public dataset, and a synthetic dataset were used along with the labeled image dataset to train the model through a novel training strategy. We conducted a fivefold cross-validation and evaluated the classification results using precision, recall, F1 score, and area under the curve (AUC). RESULTS The average precision, recall, F1 score, and AUC of our proposed multi-label classification model for the three types of prolapse were 0.84, 0.72, 0.77, and 0.91 respectively, which were improved from 0.64, 0.53, 0.57, and 0.83 from the original ResNet-50. Classification took 0.18 s to diagnose one patient. CONCLUSIONS The proposed deep learning-based model were demonstrated feasible and fast in simultaneously diagnosing three types of prolapse based on pelvic floor stress MRI, which could facilitate computer-aided prolapse diagnosis and treatment planning.

Abstract
Aims FemiCushion (FC) is a supportive device for pelvic organ prolapse (POP), but its effectiveness has not been evaluated with imaging studies. This study utilized magnetic resonance imaging (MRI) to evaluate the anatomic changes induced by FC use in patients with severe POP. Methods This prospective study examined patients with stage 3 or 4 POP who underwent treatment with FC and received a diagnostic MRI. Measurements were made in the midsagittal plane at rest and during straining with and without FC. The vertical distances from the lowest points of the anterior and posterior vaginal wall (A; P), uterine cervix or vaginal stump (C), and perineal body (PB) to the Pelvic Inclination Correction System line were measured, along with the lengths of the urogenital (UGH) and levator hiatus (LH). Results Twelve patients were included in the study. The median age was 72 (range, 56–84) years. All reference points were positioned significantly higher with the FC than without the FC (median ΔA: 11 mm, p = 0.005; ΔC: 14 mm, p = 0.011; ΔP: 6 mm, p = 0.008; ΔPB: 7 mm, p = 0.002). Median UGH and LH lengths during straining were significantly shorter with the FC than without the FC (UGH: 44 mm vs. 53 mm, p = 0.002; LH: 60 vs. 65 mm, p = 0.021). Conclusions This is the first report on the use of MRI to measure the performance of FC. Our study demonstrates that FC effectively repositioned the organs involved in POP.

Abstract
Complete rectal prolapse or rectal procidentia is a debilitating disease that presents with fecal incontinence, constipation, and rectal discharge. Definitive surgical techniques described for this disease include perineal procedures such as mucosectomy and rectosigmoidectomy, and abdominal procedures such as rectopexy with or without mesh and concomitant resection. The debate over these techniques regarding the lowest recurrence and morbidity rates, and the best functional outcomes for constipation or incontinence, has been going on for decades. The heterogeneity of available studies does not allow us to draw firm conclusions. This article aims to review the surgical techniques for complete rectal prolapse based on the current evidence base regarding surgical and functional outcomes.

Abstract
BACKGROUND When Rectocele is part of a complex pelvic organ prolapse, a full repair is recommended. The aim of this study was to evaluate the clinical and radiological results after laparoscopic surgery in patients with symptomatic rectocele and III/IV stage vaginal vault prolapse METHODS: This is a prospective cohort study of women with symptomatic rectoceles and middle compartment prolapse operated on between 2013 and 2015, who underwent a laparoscopic sacrocolpoperineopexy with synthetic Y mesh attached to puborectalis muscles, the anterior and posterior vagina wall and the sacrum. The clinical outcomes measured were symptoms of prolapse, obstructive defecation syndrome and quality of life. Radiological outcomes were distance of the vaginal vault below pubococcigeal line and depth of rectovaginal wall protrusion in dynamic pelvic resonance. RESULTS 33 patients were included. 32 of them remained asymptomatic after a three years follow-up. Significant differences were shown in the obstructed defecation score and quality of life after 6, 12 and 36 months compared to preoperatively. No differences were identified when the postoperative results were compared. Significant differences were shown in preoperative vaginal vault prolapse (3.2 cms ± 0.8 SD below the pubococcigeal Line) and rectocele size, compared with 1 and 3 years after surgery. There were no significant differences in vaginal vault prolapse when compared after 1 and 3 years. When rectocele size after 1 and 3 years was compared, significant differences were shown, but only one clinical recurrence (3%) was identified after a mean follow-up of 47 months. CONCLUSIONS Laparoscopic sacrocolpoperineopexy in patients with symptomatic rectocele and III/IV vaginal vault prolapse solves the constipation and obstructed defecation with an excellent quality of life and low clinical recurrences. Radiological deterioration, especially in rectocele size, was identified in the mid-term follow-up without clinical significance.

Abstract
Abstract
Background
Obstructed defecation syndrome is associated with varying combinations of a host of ano-rectal abnormalities, and no physical examination can demonstrate these abnormalities. The present study was aimed to evaluate the spectrum of various pelvic floor abnormalities in obstructed defecation syndrome (ODS).
Results
Of the total 302 patients imaged with age range of 18–72 years (mean age 54 years), 218 were females, and 84 were males. Ano-rectal junction descent was the commonest abnormality observed in 273 (90.3%) patients followed by rectocele (232) (76.8%), rectal intussusception (93) (30.7%), and cystocele (92) (30.4%). Cervical descent was observed in 78 (35.7%) of female patients. Spastic perineum was seen in 27 (8.9%) patients.
Conclusion
MRD serves as single stop shop for demonstrating and grading a gamut of pelvic organ abnormalities underpinning ODS which in turn helps in choosing the best treatment plan for the patient.

Abstract
We aimed to investigate the prevalence of true rectocele and obstructed defecation (OD) in patients with pelvic organ prolapse (POP), to investigate the correlation between true rectocele and OD, and to understand the diagnostic value of translabial ultrasound (TLUS) in the diagnosis of true rectocele. The patients who scheduled for POP surgery were enrolled in this study. Patients who had previous reconstructive pelvic surgery or repair of rectocele were excluded. Birmingham Bowel and Urinary symptoms questionnaires and Longo's obstructed defecation syndrome scoring system were used to assess the bowel symptoms of patients. TLUS was used to evaluate anatomical defects. P value <0.05 was considered statistically significant, and confidence intervals were set at 95%. 279 patients were included into this study. The prevalence rate of OD was 43%, and the average value of ODS score was 6.67. 17% patients presented straining at stool, 33% presented incomplete emptying, 13% presented digitations, and 12% required laxatives or enema. The prevalence rate of true rectocele was 23%. Defecation symptoms were significantly correlated with age, levator-ani hiatus, levator-ani muscle injury and true rectocele. Logistic regression showed that true rectocele and increased levator-ani hiatus were independent risk factors of OD. True rectocele was significantly correlated with straining at stool, digitation, incomplete emptying and requirement of laxatives or enema.In POP patients, the prevalence rate of true rectocele and OD was 23% and 43%, respectively. True rectocele was related to OD. TLUS was a valuable approach in anatomical evaluation of POP.

Abstract
Reporting MR imaging of pelvic floor dysfunction can be made easy if radiologists understand the aim of each MR sequence and what to report in each set of MR images. For an MR imaging report that is critical in decision making for patient management, it is of paramount importance to the radiologist to know what to look for and where to look for it. This article presents a new term, integrated MR analytical approach. A reporting template is included in which all MR findings are presented in a schematic form that can be easily interpreted by clinicians from different subspecialties.

Abstract
STUDY DESIGN A prospective single arm study. OBJECTIVES Previously we have demonstrated that magnetic resonance (MR) defecography is feasible in participants with complete spinal cord injury (SCI). The main aim of this study is to evaluate whether MR defecography can provide objective parameters correlating with the clinical manifestations of neurogenic bowel dysfunction (NBD) in participants with SCI. SETTING A monocentric study in a comprehensive care university hospital Spinal Cord Injury Center. METHODS Previously published MR defecography parameters (anorectal angle (ARA), hiatal descent (M-line) and hiatal width (H-line)) of twenty participants with SCI were now compared to a standardized clinical assessment of NBD. Descriptive statistics, correlations and t-tests for independent samples were calculated. RESULTS The significantly higher values for the ARA at rest and M-line at rest in participants with SCI correlated with the clinical assessment of bowel incontinence. Furthermore, in nearly half of the investigated SCI cohort the normally positive difference between ARA, M-line and H-line at rest and during defecation became negative suggesting pelvic floor dyssynergia as a potential mechanism underlying constipation in people with complete SCI. In fact, these participants showed a more severe clinical presentation of NBD according to the total NBD score. CONCLUSIONS MR defecography provides objective parameters correlating with clinical signs of NBD, such as constipation and bowel incontinence. Therefore, MR defecography can support pathophysiology-based decision-making with respect to specific therapeutic interventions, which should help to improve the management of NBD.

Abstract
Pelvic floor dysfunctions represent a range of functional disorders that frequently occur in adult women, carrying a significant burden on the quality of life, and its incidence tends to increase attending to the expected aging of the population. Pelvic floor dysfunctions can manifest as incontinence, constipation, and prolapsed pelvic organs. Since pelvic floor weakness is frequently generalized and clinically underdiagnosed, imaging evaluation is of major importance, especially prior to surgical correction. Given some interobserver variability of soft-tissue measurements, MR defecography allows a noninvasive, radiation-free, multiplanar dynamic evaluation of the three pelvic compartments simultaneously and with high spatial and temporal resolution. Both static/anatomic and dynamic/functional findings are important, since pelvic disorders can manifest as whole pelvic floor weakness/dysfunction or as an isolated or single compartment disorder. Imaging has a preponderant role in accessing pelvic floor disorders, and dynamic MR defecography presents as a reliable option, being able to evaluate the entire pelvic floor for optimal patient management before surgery. The purpose of this article is to address the female pelvic anatomy and explain the appropriate MR Defecography protocol, along with all the anatomic points, lines, angles, and measurements needed for a correct interpretation, to later focus on the different disorders of the female pelvic floor, illustrated with MR defecography images, highlighting the role of this technique in accessing these pathologic conditions.

Abstract
Rectal prolapse, rectal procidentia, "complete" prolapse or "third-degree" prolapse is the full-thickness prolapse of the rectal wall through the anal canal and has a significant impact on quality of life. The incidence of rectal prolapse has been estimated to be approximately 2.5 per 100,000 inhabitants with a clear predominance among elderly women. The aim of this consensus statement was to provide evidence-based data to allow an individualized and appropriate management and treatment of complete rectal prolapse. The strategy used to search for evidence was based on application of electronic sources such as MEDLINE, PubMed, Cochrane Review Library, CINAHL and EMBASE. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Gastroenterology's Chronic Constipation Task Force. Five evidence levels were defined. The recommendations were graded A, B, and C.

Abstract
PURPOSE To evaluate the utility of a defecography phase (DP) sequence in dynamic pelvic floor MRI (DPMRI), in comparison to DPMRI utilizing only non-defecography Valsalva maneuvers (VM). MATERIALS AND METHODS Inclusion criteria identified 237 female patients with symptoms and/or physical exam findings of pelvic floor prolapse. All DPMRI exams were obtained following insertion of ultrasound gel into the rectum and vagina. Steady-state free-precession sequences in sagittal plane were acquired in the resting state, followed by dynamic cine acquisitions during VM and DP. In all phases, two experienced radiologists performed blinded review using the H-line, M-line, Organ prolapse (HMO) system. The presence of a rectocele, enterocele and inferior descent of the anorectal junction, bladder base, and vaginal vault were recorded in all patients using the pubococcygeal line as a fixed landmark. RESULTS DPMRI with DP detected significantly more number of patients than VM (p<0.0001) with vaginal prolapse (231/237, 97.5% vs. 177/237, 74.7%), anorectal prolapse (227/237, 95.8% vs. 197/237, 83.1%), cystocele (197/237, 83.1% vs. 108/237, 45.6%), and rectocele (154/237, 65% vs. 93/237, 39.2%). The median cycstocele (3.2cm vs. 1cm), vaginal prolapse (3cm vs. 1.5cm), anorectal prolapse (5.4cm vs. 4.2cm), H-line (8cm vs. 7.2cm) and M-line (5.3cm vs. 3.9cm) were significantly higher with DP than VM (p<0.0001). CONCLUSIONS Addition of DP to DPMRI demonstrates a greater degree of pelvic floor instability as compared to imaging performed during VM alone. Pelvic floor structures may show mild descent or appear normal during VM, with marked prolapse on subsequent DP images.

Abstract
OBJECTIVE To compare dynamic magnetic resonance imaging (dMRI) defecography phase findings with physical examination (PE) grading in the evaluation of pelvic organ prolapse (POP). METHODS We retrospectively reviewed 274 consecutive patients who underwent dMRI with defecography. Baden-Walker grading of POP, absolute dMRI values, and grading by dMRI were collected for anterior, apical, and posterior compartments. Anatomically significant POP on PE was defined as Baden-Walker Grade ≥3 and on dMRI by dMRI Grade ≥2. A Spearman's Rank correlation was performed between absolute dMRI values and respective POP grades. RESULTS A total of 178 female patients were included. Anatomically insignificant and significant cystoceles had a 26.4% (19/72) and 84.6% (66/78) agreement respectively. Anatomically insignificant and significant apical prolapse had a 2.0% (2/100) and 62.9% (17/27) agreement respectively. Anatomically insignificant and significant posterior prolapse had a 49.5% (51/103) and 78.7% (59/75) agreement respectively. PE detected only 30% (9/30) of total dMRI detected enteroceles and misdiagnosed 10% (3/30) of these patients with a rectocele. CONCLUSION The dMRI defecography phase correlated well for anatomically significant prolapse in anterior and posterior compartments. dMRI was superior to PE for enterocele detection and was better able to distinguish an enterocele from a rectocele. Thus, dMRI may have the greatest diagnostic value in cases where the presence of an enterocele is unclear in apical and/or posterior compartments.

Abstract
INTRODUCTION AND HYPOTHESIS The objective was to evaluate the diagnostic potential of digital rectal examination in the identification of a true rectocele. METHODS This is a retrospective observational study utilising 187 archived data sets of women presenting with lower urinary tract symptoms and/or pelvic organ prolapse between August 2012 and November 2013. Evaluation included a standardised interview, ICS-POPQ, rectal examination and 4D translabial ultrasound. The main outcome measure was the diagnosis of rectocele by digital rectal palpation on Valsalva manoeuvre. This diagnosis correlated with the sonographic diagnosis of rectocele to determine agreement between digital examination and ultrasound findings. RESULTS Complete data sets were available for 180 participants. On imaging, the mean position of the rectal ampulla was 11.07 (-36.3 to 44.3) mm below the symphysis pubis; 42.8% (77) had a rectocele of a depth of ≥10 mm. On palpation, a rectocele was detected in 60 women (33%). Agreement between palpation and imaging was observed in 77%; the kappa was 0.52 (CI 0.39-0.65). On receiver operator characteristic analysis, the area under the curve was 0.854 for the relationship between rectocele pocket depth and the detection of rectocele on palpation. CONCLUSION Moderate agreement was found between digital rectal examination for rectocele and translabial ultrasound findings of a "true rectocele". Digital rectal examination may be used to identify these defects in clinical practice. Extending the clinical examination of prolapse to include rectal examination to palpate defects in the rectovaginal septum may reduce the need for defecatory proctograms for the assessment of obstructive defecation and may help triage patients in the management of posterior compartment prolapse.

Abstract
Aims: The aim was to establish an official interdisciplinary guideline, published and coordinated by the German Society of Gynecology and Obstetrics (DGGG). The guideline was developed for use in German-speaking countries. In addition to the Germany Society of Gynecology and Obstetrics, the guideline has also been approved by the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). This is a guideline published and coordinated by the DGGG. The aim is to provide evidence-based recommendations obtained by evaluating the relevant literature for the diagnostic, conservative and surgical treatment of women with female pelvic organ prolapse with or without stress incontinence. Methods: We conducted a systematic review together with a synthesis of data and meta-analyses, where feasible. MEDLINE, Embase, Cinahl, Pedro and the Cochrane Register were searched for relevant articles. Reference lists were hand-searched, as were the abstracts of the Annual Meetings of the International Continence Society and the International Urogynecological Association. We included only abstracts of randomized controlled trials that were presented and discussed in podium sessions. We assessed original data on surgical procedures published since 2008 with a minimum follow-up time of at least 12 months. If the studies included descriptions of perioperative complications, this minimum follow-up period did not apply. Recommendations: The guideline encompasses recommendations for the diagnosis and treatment of female pelvic organ prolapse. Recommendations for anterior, posterior and apical pelvic organ prolapse with or without concomitant stress urinary incontinence, uterine preservation options, and the pros and cons of mesh placements during surgery for pelvic organ prolapse are presented. The recommendations are based on an extensive and systematic review and evaluation of the current literature and include the experiences and specific conditions in Germany, Austria and Switzerland.

Abstract
Pelvic Floor Disorders (PFD) are a major public health problem in the world and decrease seriously the patient's quality of life. In case of recurrence after surgery or complex prolapse, imaging techniques can be used. Dynamic MRI, introduced in the early 1990s, offers information of the four compartments of the pelvis with a high resolution and a direct visualization of muscles and fascias in multiple planes. But for a practical use, such an expensive exam should be well correlated to symptoms and clinical examination or change surgical approach. The aim of our review was to precise the evidence regarding techniques, and indication of dynamic MRI in the assessment of pelvic floor disorders in daily practice. The first part is a review of available studies on methods of carrying out the dynamic MRI. The second part consists on the comparison of dynamic MRI to other assessment methods in case of pelvic floor disorders. Results emphasize the lack of strong level studies about the interest of dynamic MRI in the diagnosis and surgical management of pelvic organ prolapse. Although dynamic MRI appears highly reproducible between examiners, especially for the anterior compartment, its correlation with the degree of prolapse or the symptoms appears low. The most interesting field of application seems the detection of levator ani (LA) avulsion with a higher risk of prolapse and recidive in case of LA defects. More prospective, randomized, comparative studies have to be done.

Abstract
"Functional" imaging of anorectal and pelvic floor dysfunction has assumed an important role in the diagnosis and management of these disorders. Although defecography has been widely practiced for decades to evaluate the dynamics of rectal emptying, debate concerning its clinical relevance, how it should be done and interpreted continues. Due to the recognition of the association of defecatory disorders with pelvic organ prolapse in women, the need to evaluate the pelvic floor as a unit has arisen. To meet this need, defecography has been extended to include not only evaluation of defecation disorders but also the rest of the pelvic floor by opacifying the small bowel, vagina, and the urinary bladder. The term "dynamic cystocolpoproctography" (DCP) has been appropriately applied to this examination. Rectal emptying performed with DCP provides the maximum stress to the pelvic floor resulting in complete levator ani relaxation. In addition to diagnosing defecatory disorders, this method of examination demonstrates maximum pelvic organ descent and provides organ-specific quantification of organ prolapse, information that is only inferred by means of physical examination. It has been found to be of clinical value in patients with defecation disorders and the diagnosis of associated prolapse in other compartments that are frequently unrecognized by history taking and the limitations of physical examination. Pelvic floor anatomy is complex and DCP does not show the anatomical details pelvic magnetic resonance imaging (MRI) provides. Technical advances allowing acquisition of dynamic rapid MRI sequences has been applied to pelvic floor imaging. Early reports have shown that pelvic MRI may be a useful tool in pre-operative planning of these disorders and may lead to a change in surgical therapy. Predictions of hypothetical increase cancer incidence and deaths in patients exposed to radiation, the emergence of pelvic floor MRI in addition to questions relating to the clinical significance of DCP findings have added to these controversies. This review analyses the pros and cons between DCP and dynamic pelvic floor MRI, addresses imaging and interpretive controversies, and their relevance to clinical management.

Abstract
BACKGROUND Therapeutical outcome after prolapse surgery is evaluated using a standardized grading system based on maximum prolapse extent, which might not provide the full picture of the patient's subjective outcome. We therefore applied an evaluation method, which is detached from a grading system. PURPOSE To evaluate the impact of pelvic organ mobility in dynamic magnetic resonance imaging (MRI) before and after mesh-repair surgery in patients with symptomatic pelvic organ prolapse. MATERIAL AND METHODS To obtain measurements, we performed parasagittal T2-weighted turbo spin echo sequence at rest (TR, 3460 ms; TE, 85 ms; matrix, 512; slice thickness [ST], 5 mm), parasagittal T2-weighted true fast imaging with steady-state precession (TrueFISP) single-shot sequence during straining (TR, 397.4 ms; TE, 1.5 ms; matrix, 256; ST, 8 mm), and parasagittal T2-weighted TrueFISP sequence at maximum strain (TR, 4.3 ms; TE, 2.15 ms; matrix, 256; ST, 5 mm) at 1.5 T MRI. Pelvic organ prolapse (anatomical landmarks: bladder, cervix, pouch, rectum) was measured perpendicularly with reference to the pubococcygeal and the midpubic line. Pelvic organ mobility was defined as the difference between the measured distance at rest and at maximum strain for each anatomical landmark. All patients underwent mesh-repair procedure. Eighty patients could be included in this short-term follow-up study. Due to the physical diagnosis of pelvic organ prolapse, 51 underwent anterior mesh repair, 16 underwent posterior mesh repair, and 13 underwent total mesh repair. Surgery was performed by one surgeon, using mesh implants from several manufacturers. RESULTS Median values of maximum organ prolapse for bladder, cervix, pouch, and rectum preoperatively were 2.54 cm, 0.33 cm, 2.47 cm, and 0.32 cm, respectively, and 12 weeks postoperatively 0.87 cm, -1.79 cm, 1.49 cm, and 0.49 cm, respectively. Highly significant improvement (P < 0.001) of pelvic organ mobility was observed in the treated compartment at 4- and 12-week follow-up. Physical evaluation 12 weeks after mesh-repair showed an asymptomatic POP-Q stage I, if any. CONCLUSION Dynamic MRI is useful in visualizing the maximum extent of pelvic organ prolapse, as the evaluation of pelvic organ mobility documents the intraindividual therapeutic outcome detached from a grading system based on maximal prolapse values.

Abstract
PURPOSE This study prospectively compared the diagnostic capabilities of magnetic resonance (MR) imaging with conventional defecography (CD) in outlet obstruction syndrome. MATERIALS AND METHODS Nineteen consecutive patients with clinical symptoms of outlet obstruction underwent pelvic MR examination. The MR imaging protocol included static T2-weighted fast spin-echo (FSE) images in the sagittal, axial and coronal planes; dynamic midsagittal T2-weighted single-shot (SS)-FSE and fast imaging employing steady-state acquisition (FIESTA) cine images during contraction, rest, straining and defecation. MR images (including and then excluding the evacuation phase) were compared with CD, which is considered the reference standard. RESULTS Comparison between CD and MR with evacuation phase (MRWEP) showed no significant differences in sphincter hypotonia, dyssynergia, rectocele or rectal prolapse and significant differences in descending perineum. Comparison between CD and MR without evacuation phase (MRWOEP) showed no significant differences in sphincter hypotonia, dyssynergia or enterocele but significant differences in rectocele, rectal prolapse and descending perineum. Comparison between MRWEP and MRWOEP showed no significant differences in sphincter hypotonia, dyssynergia, enterocele or descending perineum but significant differences in rectocele, rectal prolapse, peritoneocele, cervical cystoptosis and hysteroptosis. CONCLUSIONS MR imaging provides morphological and functional study of pelvic floor structures and may offer an imaging tool complementary to CD in multicompartment evaluation of the pelvis. An evacuation phase is mandatory.

Abstract
PURPOSE This study was undertaken to explore the capabilities of an open-configuration, low-field, tilting, magnetic resonance (MR) system for investigating pelvic floor disorders and to compare the results obtained with the patient in the semiorthostatic and supine positions. MATERIALS AND METHODS Eighteen female patients with a diagnosis of pelvic floor disorder (physical examination and conventional defecography) underwent dynamic MR defecography (MRD) with a 0.25-T tilting MR system (G-scan, Esaote). Images were obtained after administration of contrast agent into the rectum, bladder and vagina in both the orthostatic and supine positions. Three-dimensional T2-weighted hybrid contrast-enhanced (HYCE) sequences and dynamic T1-weighted gradient echo (GE) sequences were acquired at rest, during maximal contraction of the anal sphincter, straining and defecation. RESULTS Good image quality was obtained in 15/18 patients; three presented severe artefacts due to motion, and three had incontinence, which hampered the functional studies. Better anatomical detail was obtained with MRD compared with conventional defecography. Three prolapses were observed in the semiorthostatic position only, and seven were found to be more severe in the orthostatic than in the supine position. CONCLUSIONS Dynamic MRD with an open-configuration, low-field, tilting MR system is a feasible and promising tool for studying the pelvic floor. Larger series are necessary to assess its real diagnostic value.

Abstract
The clinical treatment of patients with anorectal and pelvic floor dysfunction is often difficult. Dynamic cystocolpoproctography (DCP) has evolved from a method of evaluating the anorectum for functional disorders to its current status as a functional method of evaluating the global pelvic floor for defecatory disorders and pelvic organ prolapse. It has both high observer accuracy and a high yield of positive diagnoses. Clinicians find it a useful diagnostic tool that can alter management decisions from surgical to medical and vice versa in many cases. Functional radiography provides the maximum stress to the pelvic floor, resulting in levator ani relaxation accompanied by rectal emptying-which is needed to diagnose defecatory disorders. It also provides organ-specific quantificative information about female pelvic organ prolapse-information that usually can only be inferred by means of physical examination. The application of functional radiography to the assessment of defecatory disorders and pelvic organ prolapse has highlighted the limitations of physical examination. It has become clear that pelvic floor disorders rarely occur in isolation and that global pelvic floor assessment is necessary. Despite the advances in other imaging methods, DCP has remained a practical, cost-effective procedure for the evaluation of anorectal and pelvic floor dysfunction. In this article, the authors describe the technique they use when performing DCP, define the radiographic criteria used for diagnosis, and discuss the limitations and clinical utility of DCP.

Abstract
PURPOSE The aim of the study was to evaluate the utility of magnetic resonance imaging (MRI) pelvic landmark angles and lines in the assessment of apical vault prolapse. METHODS Seventeen women were evaluated as part of a prospective surgical trial. Baseline data are presented as a pilot study of the utility of MRI in addition to this evaluation of 6 nulliparous volunteers without prolapse and 11 parous women with symptomatic ≥ stage II uterine prolapse. Each patient underwent assessment for pelvic organ prolapse quantification (POPQ) and pelvic MRI. Pelvic landmark angles and lines were measured. Mann-Whitney Rank sum test and Spearman's Rank order correlation test were used to assess agreement. RESULTS Women with prolapse had a significantly larger h angle, g angle, and e angle at rest than those without prolapse. Correlation between apical vault descent was measured clinically by POPQ point C with MRI measurements: h angle (r = 0.61, p = 0.01), g angle (r = 0.64, p = 0.005), and e angle (r = 0.62, p = 0.007). CONCLUSION MRI measurements of pelvic landmark angles reliably differentiate between women with and without uterine prolapse and correlate best with POPQ point C.

Abstract
INTRODUCTION The purpose of the study was to assess the usefulness of dynamic MRI in patients with pelvic organ prolapse after pelvic floor repair with polypropylene mesh. MATERIALS AND METHODS Fifteen consecutive patients (mean age 66.5 years) who were scheduled for either anterior (n=9) or posterior (n=6) pelvic floor repair were prospectively evaluated by clinical assessment and dynamic MRI 1 day before and 3 months after surgery. MRI diagnoses and MRI measurements of relevant anatomical points at rest and on straining were analysed before and after surgery. RESULTS At follow-up assessment 93.3% of all patients were clinically cured. Dynamic MRI showed newly developed (n=6) or increased (n=6) pelvic organ prolapse in 80% (n=12) of all patients 3 months after pelvic floor repair. Most of them (n=11; 91.7%) affected the untreated pelvic floor compartment. On straining anatomical points of reference in the anterior pelvic floor compartment were significantly (p<0.05) elevated after anterior repair and rectal bulging was significantly (p=0.036) reduced after posterior pelvic floor repair. CONCLUSIONS In this study dynamic MRI could verify the effective support of anterior and posterior pelvic floor structures by anterior and posterior polypropylene implant respectively. But dynamic MRI demonstrates if one compartment of the pelvic floor is repaired another compartment frequently (73.3%) develops dysfunction. These results did not correspond to clinical symptoms on short-term follow-up (3 months). Studies with long-term follow-up are necessary to prove if dynamic MRI can reliably identify clinically significant pelvic organ prolapse after pelvic floor repair before the onset of symptoms.

Abstract
AIM To compare defecographic abnormalities in symptomatic men and women and to analyze differences between men and age- and symptom-matched women. METHODS Sixty-six men (mean age: 55.4 years, range: 20-81 years) who complained of constipation and/or fecal incontinence and/or pelvic pain underwent defecography after intake of a barium meal. Radiographs were analyzed for the diagnosis of rectocele, enterocele, intussusception and perineal descent. They were compared with age- and symptom-matched women (n = 198) who underwent defecography during the same period. RESULTS Normal defecography was observed in 22.7% of men vs 5.5% of women (P < 0.001). Defecography in men compared with women showed 4.5% vs 44.4% (P < 0.001) rectocele, and 10.6% vs 29.8% (P < 0.001) enterocele, respectively. No difference was observed for the diagnosis of intussusception (57.6% vs 44.9%). Perineal descent at rest was more frequent in women (P < 0.005). CONCLUSION For the same complaint, diagnosis of defecographic abnormalities was different in men than in women: rectocele, enterocele and perineal descent at rest were observed less frequently in men than in women.

Abstract
Pelvic floor function and structure are complex, and imaging (integrated with an understanding of physiology) is central to guiding the clinician in managing patients with incontinence, constipation, difficult rectal evacuation and pelvic organ prolapse. Multimodal imaging techniques such as static and dynamic imaging techniques (sometimes combined in a single sitting) have revolutionised our understanding of functional anatomy. The advent of endo-luminal imaging has increased our spatial resolution by its closer proximity to the area of interest. Dynamic imaging gives us a near physiological data set which helps us to simulate what is likely to happen in real life and gives us a better understanding of the multifactorial causes, and consequences, of pelvic floor dysfunction.

Abstract
Pelvic floor dysfunctions involving some or all pelvic viscera are complex conditions that occur frequently and primarily affect adult women. Because abnormalities of the three pelvic compartments are frequently associated, a complete survey of the entire pelvis is necessary for optimal patient management, especially before surgical correction is attempted. With the increasing use of magnetic resonance (MR) imaging in assessing functional disorders of the pelvic floor, familiarity with normal imaging findings and features of pathologic conditions are important for radiologists. Dynamic MR imaging of the pelvic floor is an excellent tool for assessing functional disorders of the pelvic floor such as pelvic organ prolapse, outlet obstruction, and incontinence. Findings reported at dynamic MR imaging of the pelvic floor are valuable for selecting patients who are candidates for surgical treatment and for choosing the appropriate surgical approach. This pictorial essay reviews MR imaging findings of pelvic organ prolapse, fecal incontinence, and obstructed defecation.

Abstract
Pelvic floor dysfunction (PFD) is a hidden women's health epidemic in the United States, with over 10% of women having a lifetime risk for undergoing a surgical repair for this problem. Given the paucity of understanding of PFD pathophysiology and the high rate of recurrence and repeat surgery, imaging plays a major role in its clinical management, especially for the preoperative assessment of patients with multicompartment defects and failed surgical repairs. The recent development of fast magnetic resonance (MR) imaging sequences allows noninvasive, radiation-free, rapid, high-resolution evaluation of the entire pelvis in one examination. The H line, M line, organ prolapse (HMO) classification system, which is applied to dynamic MR images, allows consistent standardization and grading of various forms of PFD. In addition, the HMO system clearly defines and differentiates between the two main components of PFD: pelvic floor relaxation and pelvic organ prolapse. In addition to serving as an objective diagnostic tool in patients with surgical PFD, MR imaging has tremendous potential to be used as a research tool in trying to understand the pathophysiology of these complex disorders.

Abstract
The purpose of this study was to assess the impact of new technology on both the understanding of the underlying pathophysiology and treatment of solitary rectal ulcer syndrome (SRUS). This study is a retrospective review of patients with a histologic diagnosis of SRUS (1993 to 2007) complimented with a prospective database of those patients studied with defecography and dynamic pelvic MRI. Thirty patients were available for evaluation. A polyp or mass was present in 74 per cent. Ulcers were found in only 23 per cent. All 12 patients undergoing defecography demonstrated rectorectal intussusception. Dynamic MRI of the pelvis revealed pronounced anorectal redundancy and lack of mesorectosacral fixation with mild to severe pelvic floor descent in all four patients studied. Fiber with or without stool softeners was the initial treatment in all patients with resolution of symptoms in 65 per cent. One patient with refractory symptoms underwent a stapled transanal rectal resection with complete resolution of symptoms. Occult rectorectal intussusception appears to be the operant anatomic pathology in SRUS. Anorectal redundancy with lack of mesorectosacral fixation may contribute to the process. All patients should be studied with defecography and dynamic MRI. Stapled transanal rectal resection may offer a promising surgical option.

Abstract
Several imaging modalities are available ranging from fluoroscopic techniques to ultrasonography and MRI for the evaluation of patients with pelvic floors disorders. High-resolution ultrasonography and MRI not only provide superior delineation of the pelvic floor anatomy but also reveal pathology and functional changes. This article focuses on standard imaging procedures including defecography, ultrasonography, and MRI and discusses its use in clinical practice by illustrating both normal and abnormal patterns.
