Patients presenting with primary evacuatory difficulty have a multiplicity of pelvic floor and perineal soft tissue anomalies. The radiological assessment of these patients requires modalities which monitor the dynamic interaction of pelvic organs during provocative manoeuvres such as straining and simulated defaecation. The advantages and disadvantages of these complementary modalities, (dynamic magnetic resonance imaging, dynamic transperineal sonography and dynamic 2- and 3-dimensional endoanal sonography) are provided in this position paper.

Objectives This study aimed to examine the validity and reliability of a Web-based version of the epidemiology of prolapse and incontinence questionnaire (EPIQ). Methods Participants included 876 women age 38 to 65 years attending primary care clinics in the Salt Lake Valley. Women completed a single Web- or paper-based version of the symptom bother questions from EPIQ, and a subset repeated the same or opposite method at 2 separate time points. To assess subscales for the Web-based version factor, analysis of the 22 EPIQ items related to pelvic floor disorder symptoms was performed using principal components analysis and varimax rotation. Internal consistency was assessed using coefficient α. Test-retest and intermethod reliability were assessed using intraclass correlation coefficients for domain scores. Correlations above 0.70 were considered acceptable. Results Overall, 384 and 492 women completed at least 1 Web and 1 paper EPIQ and 93% were white with mean age of 50 (7) years. Of these, 63 completed Web-Web, 57 Web-paper, 47 paper-Web, and 109 paper-paper test-retest. Overall, factor analyses were consistent with the 7 domains of the original EPIQ. Cronbach α for the 4 symptomatic pelvic floor disorder domains and range of test-retest reliability for the various administration methods were similar to the original EPIQ instrument. Correlations for domain scores were above 0.70, except the anal incontinence scale (intraclass correlation coefficients, 0.68.) Conclusions Web administration of the EPIQ has similar psychometric properties with comparable internal consistency and test-retest reliability when administered in the same modality. Reliability between both methods of administration is acceptable.

The paper by Kaysan et al. [1] is timely, given the vast increase in the eroded and transected urethras which are increasingly being reported as a consequence of the midurethral sling operation. A Martius transposition graft is an important tool for management of such problems. From a practical perspective, a vascularized fat graft without the bulbocavernosus muscle attached is sufficient as an interposition flap. Deeper dissection and transposition of the bulbocavernosus only creates the potential for bleeding, hematomas, and infections. It is not necessary in our experience. We would draw attention to the “skin–on” Martius graft which offers several advantages to the simple fat graft, not least of which is restoration of vaginal skin volume and elasticity, an absolute requirement in patients who have the “Tethered Vaginal Syndrome” [2–4]. In patients with radiation necrosis, adding healthy skin to the fat graft may be helpful to the healing process. In regards to damage inflicted by the TVT to the urethra, a “skin–on” Martius graft allows another tape to be applied over the skin to cover the urethra after the urethral fistula has been repaired [5]. A “skin–on” Martius graft is especially helpful in patients with the “Tethered Vaginal Syndrome”, Figure 1. The “Tethered Vaginal Syndrome” is not a well recognized condition. It was first reported in 1990 [2]. It is an entirely iatrogenic condition that needs to be considered in patients with scarring after vaginal operations or after Burch colposuspension. The incontinence is severe. Urinary stress incontinence is very mild or absent. It is somewhat equivalent to ‘motor detrusor instability’ (MDI). The classical symptom is commencement of uncontrolled urine leakage as soon as the patient's foot touches the floor, indeed, often commencing as the patient rolls over to get out of bed. The patient does not complain of bed–wetting during the night. The symptoms are caused by loss of elasticity in the bladder neck area of the vagina: the ‘zone of critical elasticity’ (ZCE). Because scar tissue contracts with time, it may present twenty years after vaginal repair or bladder neck elevation. This condition can be cured by plastic surgery, whose aim is to restore elasticity to the bladder neck area of the vagina. Figure 1 Zone of critical elasticity (ZCE) allows for separate function of the three directional vectors for urethral closure [4]. Figure 1 illustrates why elasticity at the ZCE is necessary for the separate function of urethral (U) and bladder neck (BN) closure ... Pathogenesis of the tethered vagina syndrome This condition is entirely iatrogenic and is caused by excessive tightness in the bladder neck area of the vagina [2, 3]. It is far more common in regions where surgeons are taught to remove significant amounts of vaginal skin during vaginal repairs. Often, there is very little stress incontinence. The reason is that cough creates short and sharp fast–twitch contractions, which may provide sufficient elasticity at the ZCE to prevent urine leakage on coughing. Getting out of bed in the morning stretches ZCE far more, as the pelvic floor contracts to support all the intra–abdominal organs. This explains the classical symptom: commencement of uncontrolled urine leakage as soon as the patient's foot touches the floor. A scar at the ZCE ‘tethers’ the more powerful backward forces (arrows, Figure 1) to the weaker forward forces, so the bladder is pulled open as in micturition. Specific clinical findings Generally, the tightness in the bladder neck area of the vagina is obvious on speculum examination. Often no urine loss is evident during coughing or even straining. On ultrasound there is generally very little descent of the bladder neck, perhaps only 2 to 3 mm. One provocative test, which may be useful, is to grasp the bladder base part of the vagina gently with Littlewood's forceps and press backwards while asking the patient to cough. This removes any residual elasticity at the ZCE, and very frequently a spurt of urine comes out when there was previously no urine loss on coughing. This test is specific for low elasticity at the ZCE, not necessarily for the tethered vagina per se. Care must be taken not to clamp the forceps. This may cause severe pain, a consequence of the visceral nerve innervation of the vagina. Skin–on Martius flap surgery, Figure 1 The aim is to restore elasticity in the bladder neck area of the vagina, the ZCE, so that oppositely acting vectors can act independently of each other. No matter what technique is used, it is essential to dissect the vagina from the bladder neck and urethra, and then to free all scar tissue from urethra, bladder neck (‘urethrolysis’), and pubic bones. The surgical principle applied is that fresh vaginal tissue must be brought to the bladder neck area of vagina. If there is a severe shortage of tissue, the only solution is a skin graft. This can be a free graft, a Martius labium majus skin graft, or a split labium minus flap graft. A free graft can be problematic as up to one third may not ‘take’ or shrink excessively. Labium minus or Martius grafts are technically challenging, but bring their own blood supply. Cure rates reported with this operation exceed 80% [6]. ZCE and the urethral (U) and bladder neck (BN) closure mechanisms. ZCE extends from mid–urethra to the bladder neck area of the vagina. A scar at the ZCE tethers the PCM (pubococcygeus) muscle vector to the levator plate/longitudinal muscle of the anus (LP/LMA) vectors. As LP/LMA are more powerful, the posterior urethral wall is pulled open, from C to O, resulting in uncontrolled urine loss. C = closed urethra; O = open urethra; PUL = pubourethral ligament; PS = pubic symphysis.

Web-based questionnaires are increasingly employed for clinical research. To investigate whether web-based and paper versions of the Pelvic Floor Distress Inventory 20 (PFDI-20) and Pelvic Floor Impact Questionnaire 7 (PFIQ-7) yield similar results, we compared results obtained with these two modes of administration. Women with pelvic floor disorders completed both versions of these questionnaires. Scores between modes of administration were compared using the paired t test and the intraclass correlation coefficient (ICC). Among the 52 participants, there were no significant differences in scores or scale scores between the web-based and paper questionnaires. The ICC was 0.91 for the PFDI-20 score and 0.81 for the PFIQ-7 score (p < 0.001 for each). The web-based format was preferred by 22 participants (53%), ten (24%) preferred the paper format, and nine (21%) had no preference. The acceptability and score equivalence recommend these web-based questionnaires as an alternative to paper questionnaires for clinical research.

Stress urinary incontinence (SUI) is defined as a complaint of inadvertent loss of urine occurring as a result of an increase in intraabdominal pressure, in the absence of a detrusor muscle contraction [1]. Estimates of the prevalence vary widely in the published literature, due in part to differing terminologies, diagnostic approaches, and populations studied [1–3]. It has been reported that SUI affects up to 14% of premenopausal women and up to 35% of postmenopausal women [4, 5], unfavourably affecting quality of life (QoL), sexual function, and mental health [6, 7]. Pathophysiologically, SUI is caused by urethral deficiency and impairment of supportive structures such as the levator ani muscle, endopelvic fascia, and pubourethral ligament [8]. The beneficial effect of pelvic floor muscle training (PFMT) on female urinary incontinence and pelvic organ prolapse was first described in 1948 by Arnold Kegel, who reported an astonishing success rate of 84% [9]. More recent studies have demonstrated somewhat lower success rates of PFMT than those reported by Kegel, but still in the impressive range from 56 to 75% based on improved clinical outcomes [10]. Strong evidence and grade A recommendations support the use of PFMT as the first-line conservative treatment for SUI [11]. Although alternative exercise regimens for SUI have been investigated, their clinical implementation is not yet recommended [12]. Other conservative therapeutic options for SUI include vaginal cones, bladder training, as well as electrical or magnetic stimulation. Extracorporeal magnetic stimulation (EMS) is a non-invasive, effective, acceptable, and safe therapeutic modality for SUI [6, 7]. In EMS, induction of a changing magnetic field results in a flow of electrons within the field, controlled depolarisation of the adjacent nerves, and subsequent muscular contraction [13]. Although the optimal frequency and duration of treatment are not yet established, findings of a systematic review have suggested that higher frequency and pulse duration provide an adequate modality for achieving treatment efficacy [14]. At our clinic, which is the largest Croatian urogynaecological referral centre, EMS is routinely offered as an alternative to women who are not willing to perform Kegel exercises. Considering that a direct comparison of these two common conservative methods is lacking, we decided to perform a randomized controlled trial comparing the efficacy of PFMT versus EMS for the treatment of SUI. In this paper we describe the protocol of the study.

Objective To assess the predictive value of measures of levator hiatal distension at rest and on maximum Valsalva maneuver for symptoms of vaginal laxity. Methods This was a retrospective study of women seen at a tertiary urogynecological unit. All women underwent a standardized interview, clinical examination and four‐dimensional translabial ultrasound examination. Area, anteroposterior diameter (APD) and coronal diameter (CD) of the levator hiatus were measured at rest and on maximum Valsalva maneuver in the plane of minimal hiatal dimensions using the rendered volume technique, by an operator blinded to all clinical data. The association between levator hiatal measurements and vaginal laxity was assessed, and receiver‐operating‐characteristics (ROC)‐curve analysis was used to determine their predictive value. Results Data from 490 patients were analyzed. Mean age was 58 (range, 18–88) years, and vaginal laxity was reported by 111 (23%) women. Measurements obtained on maximum Valsalva were significantly larger in women who reported vaginal laxity than in those who did not, with mean levator hiatal area, APD and CD of 30.45 ± 8.74 cm2, 7.24 ± 1.16 cm and 5.60 ± 0.89 cm, respectively, in the vaginal‐laxity group, compared with 24.84 ± 8.63 cm2, 6.64 ± 1.22 cm and 5.01 ± 0.97 cm in the no‐laxity group (P

Objectives To measure the length, width and area of the urogenital hiatus (UH), and the length and mean echogenicity (MEP) of the puborectalis muscle (PRM), automatically and observer‐independently, in the plane of minimal hiatal dimensions on transperineal ultrasound (TPUS) images, by automatic segmentation of the UH and the PRM using deep learning. Methods In 1318 three‐ and four‐dimensional (3D/4D) TPUS volume datasets from 253 nulliparae at 12 and 36 weeks' gestation, two‐dimensional (2D) images in the plane of minimal hiatal dimensions with the PRM at rest, on maximum contraction and on maximum Valsalva maneuver, were obtained manually and the UH and PRM were segmented manually. In total, 713 of the images were used to train a convolutional neural network (CNN) to segment automatically the UH and PRM in the plane of minimal hiatal dimensions. In the remainder of the dataset (test set 1 (TS1); 601 images, four having been excluded), the performance of the CNN was evaluated by comparing automatic and manual segmentations. The performance of the CNN was also tested on 117 images from an independent dataset (test set 2 (TS2); two images having been excluded) from 40 nulliparae at 12 weeks' gestation, which were acquired and segmented manually by a different observer. The success of automatic segmentation was assessed visually. Based on the CNN segmentations, the following clinically relevant parameters were measured: the length, width and area of the UH, the length of the PRM and MEP. The overlap (Dice similarity index (DSI)) and surface distance (mean absolute distance (MAD) and Hausdorff distance (HDD)) between manual and CNN segmentations were measured to investigate their similarity. For the measured clinically relevant parameters, the intraclass correlation coefficients (ICCs) between manual and CNN results were determined. Results Fully automatic CNN segmentation was successful in 99.0% and 93.2% of images in TS1 and TS2, respectively. DSI, MAD and HDD showed good overlap and distance between manual and CNN segmentations in both test sets. This was reflected in the respective ICC values in TS1 and TS2 for the length (0.96 and 0.95), width (0.77 and 0.87) and area (0.96 and 0.91) of the UH, the length of the PRM (0.87 and 0.73) and MEP (0.95 and 0.97), which showed good to very good agreement. Conclusion Deep learning can be used to segment automatically and reliably the PRM and UH on 2D ultrasound images of the nulliparous pelvic floor in the plane of minimal hiatal dimensions. These segmentations can be used to measure reliably UH dimensions as well as PRM length and MEP. © 2018 The Authors.

Introduction Pelvic floor muscles dysfunction is one of the most important etiologies of coccydynia; therefore, manual therapies have been proposed as the first line of treatment. The purpose of this study was to investigate the effect of biofeedback as a new approach in the treatment of coccydynia. Methods Thirty women were randomized into two groups. Both groups were injected with the corticosteroid. One group received pelvic floor muscle exercises plus biofeedback while the other group only performed exercises. The patient's pain was measured using the Visual Analog Scale (VAS) in the first visit and after 1, 2, and 6 months of follow-up as well as Dallas pain and SF-36 quality of life questionnaires before and 2 months after the treatment. Results Pain had improved significantly after 1, 2, and 6 months in both groups compared to the baseline. However, the amount of change was not different between the groups at any time interval. The results were the same for the Dallas pain scale and SF-36 quality of life questionnaire. Conclusion Adding biofeedback to pelvic floor muscle exercises did not lead to any further improvement in the management of chronic coccydynia. Further studies with larger sample sizes may reveal the effect of biofeedback more clearly.

Urinary incontinence in the general population occurs in 7% of non-pregnant women under 39 years old, 17% of those 40 to 59 years old, and 23–32% of those over 60 years old. In athletes the prevalence is higher, especially in high-impact training and gravity sports. Pelvic floor muscles (PFM) have two important roles; they serve as the support for abdominal organs and are crucial for closure of the urethra, vagina and rectum. We present the proper mechanisms of PFM caudal contractions with proper abdominal muscle control to avoid excessive intra-abdominal pressure. Pelvic floor sonography is discussed as the only objective method for pelvic floor examination among sportswomen and a tool which should be used routinely by urophysiotherapists and urogynecologists. A multidisciplinary individualized approach to stress urinary incontinence among athletes is presented including: physiotherapy, diagnostic imaging, use of a pessary, tampons, pharmacologic and surgical treatment. We present guidelines for stress urinary incontinence treatment in sportswomen of different age.

The anatomical positions of pelvic floor organs are maintained mainly by ligaments and muscles. Long-term excessive mechanical tension stimulation of pelvic floor tissue beyond the endurance of ligaments or muscles will lead to the occurrence of pelvic organ prolapse (POP). In addition, cytoskeletal reconstitution is a key process by which cells respond to mechanical stimulation. The aim of the present study was to investigate the protective effect of actin cytoskeleton to resist mechanical stretching (MS)-induced apoptosis in parametrial ligament fibroblasts (PLFs) and the underlying mechanisms. MS provided by a four‑point bending device could significantly induce apoptosis of PLFs from non-POP patients, which exhibited an apoptosis rate close to that of PLFs from POP patients, and the apoptosis rate was higher following latrunculin A (Lat-A, a potent inhibitor of actin) treatment. In addition, Nr4a1 and Bax expression was increased while Bcl-2 and caspase-3 expression was clearly decreased after treatment with MS and Lat-A. However, the apoptosis induced by MS was reduced when the expression of Nr4a1 was downregulated by siRNA. These outcomes reveal a novel mechanism that links the actin cytoskeleton and apoptosis in PLFs by Nr4a1; this mechanism will provide insight into the clinical diagnosis and treatment of POP.

Objectives The introduction of three‐dimensional (3D) analysis of the puborectalis muscle (PRM) for diagnostic purposes into daily practice is hindered by the need for appropriate training of observers. Automatic segmentation of the PRM on 3D transperineal ultrasound may aid its integration into clinical practice. The aims of this study were to present and assess a protocol for manual 3D segmentation of the PRM on 3D transperineal ultrasound, and to use this for training of automatic 3D segmentation method of the PRM. Methods The data used in this study were derived from 3D transperineal ultrasound sequences of the pelvic floor acquired at 12 weeks' gestation from nulliparous women with a singleton pregnancy. A manual 3D segmentation protocol was developed for the PRM based on a validated two‐dimensional segmentation protocol. For automatic segmentation, active appearance models of the PRM were developed, trained using manual segmentation data from 50 women. The performances of both manual and automatic segmentation were analyzed by measuring the overlap and distance between the segmentations. Intraclass correlation coefficients (ICCs) and their 95% CIs were determined for mean echogenicity and volume of the puborectalis muscle, in order to assess inter‐ and intraobserver reliabilities of the manual method using data from 20 women, as well as to compare the manual and automatic methods. Results Interobserver reliabilities for mean echogenicity and volume were very good for manual segmentation (ICCs 0.987 and 0.910, respectively), as were intraobserver reliabilities (ICCs 0.991 and 0.877, respectively). ICCs for mean echogenicity and volume were very good and good, respectively, for the comparison of manual vs automatic segmentation (0.968 and 0.626, respectively). The overlap and distance results for manual segmentation were as expected, showing an average mismatch of only 2–3 pixels and reasonable overlap. Based on overlap and distance, five mismatches were detected for automatic segmentation, resulting in an automatic segmentation success rate of 90%. Conclusions This study presents a reliable manual segmentation protocol and automatic 3D segmentation method for the PRM, which will facilitate future investigation of the PRM, allowing for the reliable measurement of potentially clinically valuable parameters such as mean echogenicity. © 2017 The Authors.

Background App-based treatment for urinary incontinence is a proven effective and cost-effective alternative to care as usual, but successful implementation requires that we identify and address the barriers and facilitators associated with app use. Objective The goal of the research was to explore the factors influencing app-based treatment for urinary incontinence and identify which barriers or facilitators are associated with treatment success or failure. Methods We used a sequential explanatory mixed methods design to connect the results of a randomized controlled trial with data from semistructured interviews. This previous RCT had shown the noninferiority of app-based treatment compared with care as usual for urinary incontinence over 4 months. Participants who reported success or failure with app-based treatment, as measured by the change in International Consultation on Incontinence Modular Questionnaire Urinary Incontinence Short Form symptom score, were selected for telephone interview by purposive sampling (n=17). This study reports mainly on the qualitative component of our mixed methods study. Qualitative analyses were conducted in two ways. First, we analyzed the qualitative data of all interviewed participants and discussed the relationships between the main themes. Second, the experiences between the success (n=9) and failure group (n=8) were compared and contrasted to explore factors that were positively or negatively associated with the quantitative effect of app-based treatment. These factors were then interpreted as barriers to and facilitators of successful app-based treatment. Results Four interrelated themes were identified as affecting the app based treatment effect: adherence, personal factors, app factors, and awareness. Qualitative analyses of the relationships between the themes showed that adherence-related factors directly influenced treatment effect in both a positive and negative matter. In turn, adherence was also positively and negatively influenced by the other 3 themes. Additionally, awareness was positively influenced by the treatment effect. Within these themes, several factors were identified that acted as barriers (eg, unrealistic expectation of time investment and interfering personal circumstances), facilitators (eg, strict integration of exercises and prior pelvic floor muscle therapy), or both (eg, personality traits and increased awareness of symptoms). Conclusions This study shows that the effect of app-based treatment for urinary incontinence is mainly influenced by adherence, which in turn is affected by personal factors, app-based factors, and awareness. The identified factors could function as both facilitators and barriers depending on the user and interaction with other themes. Insight into these facilitators and barriers could lead to improved implementation and increased treatment effectiveness by targeting women most likely to benefit and through further development of the app. International Registered Report Identifier (IRRID) RR2-10.1002/nau.23507

Introduction: This article reports the prevalence of self-reported voiding complaints and the relationship with other pelvic floor and bladder dysfunctions (PFD).Materials and Methods: Women with a variety of PFDs were referred to the pelvic care center. A standardised questionnaire on 6 PFDs was used. Frequencies of patient characteristics, PFDs and voiding complaints were calculated. Cross tabulation was used to investigate correlations and Pearson correlation coefficients to reveal the strength of the association between PFDs and self-reported voiding complaints.Results: Data of 4470 women were included. Prevalence of (self-reported) voiding Lower urinary tract symptoms was 59.5%. Incomplete bladder emptying is the most prevalent voiding complaint. Self-reported voiding complaints are weakly correlated to age (r = 0.15, p < 0.01) and have moderate correlation with self-reported recurrent urinary tract infections (r = 0.34, p < 0.01), pelvic floor, bladder and bowel complaints. However, the correlation between the feeling of incomplete bladder emptying and the presence of recurrent urinary tract infections is weak (r = 0.06, p = 0.02).Conclusion: Voiding complaints have a high prevalence and symptom bother in women visiting a pelvic care center.

Background Persistent genital arousal disorder/genito-pelvic dysesthesia (PGAD/GPD) is a highly distressing yet poorly understood condition characterized by persistent genito-pelvic sensations, often described as “genital arousal,” which occur in the absence of sexual desire. PGAD/GPD is associated with significant impairment in psychosocial and daily functioning; however, there are currently no empirically validated treatment algorithms for PGAD/GPD. Pelvic floor physical therapy exercises have been found to be effective at reducing other forms of genito-pelvic discomfort, such as vulvodynia, and may also be beneficial to those experiencing PGAD/GPD. Many individuals with PGAD/GPD report difficulty finding a health care provider who is knowledgeable about PGAD/GPD; therefore, pelvic floor education and exercises in an online format may have the potential to reach more individuals in need. Objective This study examined the feasibility of an online pelvic floor group education program; descriptively assessed outcomes related to distress, discomfort, catastrophizing, and mood; and obtained feedback from participants in order to inform the development of improved online group programs. Methods Fourteen women with current symptoms of PGAD/GPD attended an online, 8-session pelvic floor group education program. Participants completed questionnaires of symptoms (ie, symptom distress, discomfort) and psychosocial well-being (ie, depression, anxiety, symptom catastrophizing) prior to the group sessions (Time 1), immediately after the final group session (Time 2), and 6 months following the final group session (Time 3). Participants also completed an anonymous feedback questionnaire immediately following the group program. Results Overall, participants who attended a larger number of the group sessions (>5 sessions, n=7) appeared to report lower baseline (Time 1) symptoms and psychosocial impairment than those who attended fewer sessions ( Conclusions Online interventions provide an opportunity to reach international participants who may otherwise struggle to access a knowledgeable provider for their PGAD/GPD symptoms. Addressing barriers may help to increase participants’ abilities to engage in the program. Future programs may seek to integrate a greater focus on relaxation strategies and cognitive-affective strategies for managing PGAD/GPD symptoms.

This study examined the effects of different training loads on pelvic floor muscle (PFM) activity in swimming. Twelve female swimmers were included in this study (23.71±1.44 y.o.; 167±5.89 cm; 62.05±8.89 kg). They took part in an experiment with two different stages of load in swimming training. For the pelvic floor muscle assessment the Glazer Protocol was used. To assess swimming technique, David Pyne's Stroke Mechanics Test was used. A statistically significant increase in surface electromyography (sEMG) values appeared in the fifth R (rest after contraction) in the quick flick stage of the measurement protocol of PFM at the third measurement time (7.71±4.49 μV) compared to the first measurement time (6.25±4.43 μV) with p≤0.05. Increasing the training load may cause unwanted changes in the level of electrical activity of pelvic floor muscles.

Purpose: Hartmann’s procedure is a well-established alternative in colorectal surgery when a primary anastomosis is contraindicated. However, the rectal remnant may cause complications. This study was designed to investigate the occurrence of pelvic sepsis after Hartmann’s procedure and identify possible risk factors. Methods: All patients who underwent Hartmann’s procedure between 2005 and 2012 were identified by the in-hospital registry. Information about pelvic sepsis and potential preoperative, perioperative, and postoperative risk factors was obtained by review of the medical records. Results: 172 patients were identified (97 females); they were aged 74 ± 11 years. Surgery was performed due to cancer (49%) or diverticulitis (35%) and other benign disease (16%). Rectal transection was carried out anywhere between the pelvic floor and the promontory. Pelvic sepsis developed in 6.4% (11/172) of patients. Pelvic sepsis was associated with preoperative radiotherapy (p = 0.03) and Hinchey grade III and IV (p = 0.02) in those patients who underwent Hartmann’s procedure for diverticular disease. Conclusion: Hartmann’s procedure is a safe operation when an anastomosis is contraindicated since the incidence of pelvic sepsis is low. Preoperative radiotherapy and Hinchey grade III and IV may be risk factors for the development of pelvic sepsis.

Methods: We retrospectively investigated the data of 168 patients diagnosed with recurrent pelvic cancer treated at Fudan University Shanghai Cancer Center between January 2008 and December 2012. The following were collected depending on availability: operative report, histological report, specimen photographs, initial preoperative images, images confirming local recurrence, and clinical history. Results: A total of 203 lesions of local recurrence were identified. The most common sites of pelvic recurrence were the mesorectum, including the anastomotic stoma in 53.0% of cases; presacral space in 27.4%, and pelvic floor and perineum in 21.4% the cases. Recurrence was most common in the lower pelvic region (i.e., below the upper border of the acetabulum), accounting for approximately 76.2% (128 cases) of cases. In patients with mid-rectal and distal rectal carcinoma

Introduction: Implants used to treat patients with urogynecological conditions are well visible in US examination. The position of the suburethral tape (sling) is determined in relation to the urethra or the pubic symphysis. Aim of the study: The study was aimed at assessing the accuracy of measurements determining suburethral tape location obtained in pelvic US examination performed with a transvaginal probe. Material and methods: The analysis covered the results of sonographic measurements obtained according to a standardized technique in women referred for urogynecological diagnostics. Data from a total of 68 patients were used to analyse the repeatability and reproducibility of results obtained on the same day. Results: The intraclass correlation coefficient for the repeatability and reproducibility of the sonographic measurements of suburethral tape location obtained with a transvaginal probe ranged from 0.6665 to 0.9911. The analysis of the measurements confirmed their consistency to be excellent or good. Conclusions: Excellent and good repeatability and reproducibility of the measurements of the suburethral tape location obtained in a pelvic ultrasound performed with a transvaginal probe confirm the test’s validity and usefulness for clinical and academic purposes.

BackgroundThe postpartum period is a vulnerable time for the pelvic floor. Early implementation of pelvic floor muscle exercises, appropriately termed as pelvic floor muscle training (PFMT), in the postpartum period has been advocated because of its established effectiveness. The popularity of mobile health (mHealth) devices highlights their perceived utility. The effectiveness of various mHealth technologies with claims to support pelvic floor health and fitness is yet to be substantiated through systematic inquiry. ObjectiveThe aim of this study was to determine the acceptability, feasibility, and potential effect on outcomes of an mHealth device purposed to facilitate pelvic floor muscle training among postpartum women. MethodsA 16-week mixed methods pilot study was conducted to evaluate outcomes and determine aspects of acceptability and feasibility of an mHealth device. All participants received standardized examination of their pelvic floor muscles and associated instruction on the correct performance of PFMT. Those randomized to the iBall intervention received instructions on its use. Schedules for utilization of the iBall and PFMT were not prescribed, but all participants were informed of the standard established recommendation of PFMT, which includes 3 sets of 10 exercises, 3 to 4 times a week, for the duration of the intervention period. Quantitative data included the measurement of pelvic floor muscle parameters (strength, endurance, and coordination) following the PERFECT assessment scheme: Incontinence Impact Questionnaire scores and the Urogenital Distress Inventory (UDI-6) scores. Aspects of acceptability and feasibility were collected through one-to-one interviews. Interview transcripts were analyzed using Thorne’s interpretive description approach. ResultsA total of 23 women with a mean age of 32.2 years were randomized to an intervention group (n=13) or a control group (n=10). Both groups improved on all measures. The only statistically significant change was the UDI-6 score within both groups at 16 weeks compared with baseline. There was no statistically significant difference between the intervention group and control group on any outcomes. Most participants using the iBall (n=10, 77%) indicated value in the concept of the mHealth solution. Technical difficulties (n=10, 77%), a cumbersome initiation process (n=8, 61%), and discomfort from the device (n=8, 61%) were reasons impeding intervention acceptability. Most participants (n=17, 74%) indicated that the initial assessment and training was more useful than the mHealth solution, a tenet that was echoed by all control group participants. ConclusionsOur pilot study demonstrated the potential for mHealth solution–enhanced PFMT in the early postpartum period. Usability issues in hardware and software hindered feasibility and acceptance by the participants. Our findings can inform the redesign of mHealth solutions that may be of value if acceptability and feasibility issues can be overcome.

Near-infrared spectroscopy (NIRS) muscle oxygenation data are relied on in sports medicine. Many women with urinary incontinence (UI) have dysfunctional pelvic floor muscles (PFMs) but their evaluation lacks such measures; a transvaginal NIRS interface would enable the PFM to be interrogated. Paired miniature fiber-optic cables were configured on a rigid foam insert so their emitter detector arrays with an interoptode distance of 20 mm apposed the right and left inner sides of a disposable clear plastic vaginal speculum, and linked to a standard commercial NIRS instrument. Measurement capability was assessed through conduct of three maximum voluntary contractions (MVCs) and one sustained maximum voluntary contraction of the PFM with calculation of HbDiff (½RT), a validated muscle reoxygenation kinetic parameter. In all four asymptomatic controls, mean age 40, mean BMI 21.4, MVCs were associated with changes in PFM oxyhemoglobin (O2Hb), deoxyhemoglobin (HHb) concentration, and their difference (HbDiff) comparable to those in voluntary muscle sports medicine studies. NIRS data during recovery (reoxygenation) allowed calculation of HbDiff (½RT). New techniques are called for to evaluate UI. This NIRS interface warrants further development as the provision of quantitative reoxygenation kinetics offers more comprehensive evaluation of patients with PFM dysfunction.

Objective To measure the long‐term impact of surgical treatment for vulval cancer upon health‐related quality of life and pelvic floor outcomes during the first year of therapy. Methods Prospective, longitudinal, mixed‐methods study. Twenty‐three women aged >18 years with a new diagnosis of vulval cancer were recruited. The EORTC QLQ C30, SF‐36 and an electronic pelvic floor assessment questionnaire (ePAQ‐PF) were administered at baseline (pre‐treatment) and 3, 6, 9 and 12 months post‐treatment. Mixed effects repeated measures models (all adjusted for age and BMI) were used to investigate changes over time and differences between cancer stage. Qualitative interviews were carried out with 11 of the women and analysed using a thematic approach. Results Mean age was 59.9 years (SD = 15.3; range = 23.8–86.6 yrs). Mean BMI was 30.0 (SD = 4.5; range = 24.4–38.2). Sixteen women had early (Stage 1 to 2B), and seven women had advanced stage disease (Stage 3 to 4B). Questionnaire scores revealed that physical and social functioning, fatigue, pain and general sex life were significantly worse at 12 months than pre‐treatment (p = < 0.05). Qualitative analysis revealed multiple treatment side effects which were perceived as severe and enduring. Women with advanced vulval cancer had significantly worse SF‐36 mental health scores at 12 months compared to women with early stage disease (p = 0.037). Conclusions Surgery for vulval cancer has long‐term implications which can be persistent 12 months post‐treatment. High rates of morbidity relating to lymphoedema and sexual function re‐enforce the need for specialist clinics to support women who suffer these complications. © 2015 The Authors.

Background Many women experience urgency (UUI) and mixed (MUI) urinary incontinence but commonly hesitate to seek care. Treatment access and self-management for these conditions can be supported through eHealth approaches. Objective This study aimed to investigate the efficacy of the mobile app Tät II for self-management of UUI and MUI in women. Methods This randomized controlled trial included women ≥18 years old with UUI or MUI and ≥2 leakages per week. Those with red-flag symptoms were excluded. Participants were recruited via analog and digital advertisements and screened for initial selection through a web-based questionnaire. Data were collected using another questionnaire and a 2-day bladder diary. A telephone interview confirmed the symptom diagnosis. Participants were randomized (1:1) to receive access to a treatment app (including pelvic floor muscle training, bladder training, psychoeducation, lifestyle advice, tailored advice, exercise log, reinforcement messages, and reminders) or an information app (control group), with no external treatment guidance provided. The primary outcome was incontinence symptoms at the 15-week follow-up, measured using the International Consultation on Incontinence Questionnaire (ICIQ)−Urinary Incontinence Short Form (ICIQ-UI SF). Urgency symptoms were assessed using the ICIQ−Overactive Bladder Module (ICIQ-OAB) and quality of life using the ICIQ−Lower Urinary Tract Symptoms Quality of Life Module (ICIQ-LUTSqol). Incontinence episode frequency (IEF) was calculated per bladder diary entries. Improvement was measured using the Patient’s Global Impression of Improvement. All outcomes were self-reported. Cure was defined as no leakages per the bladder diary. Intention-to-treat analysis was performed. Results Between April 2017 and March 2018, 123 women (mean age 58.3, SD 9.6 years) were randomized to the treatment (n=60, 2 lost to follow-up) or information (n=63) group. Of these, 35 (28%) women had UUI, and 88 (72%) had MUI. Mean ICIQ-UI SF score at follow-up was lower in the treatment group than in the information group (estimated difference −3.1, 95% CI −4.8 to −1.3). The estimated between-group difference was −1.8 (95% CI −2.8 to −0.99) for mean ICIQ-OAB score and −6.3 (95% CI −10.5 to −2.1) for the mean ICIQ-LUTSqol score at follow-up. IEF reduction from baseline to follow-up was greater in the treatment group (−10.5, IQR −17.5 to −3.5) than in the information group (P Conclusions The treatment app was effective for improving urgency and mixed incontinence in women. When self-management is appropriate, this app may be a good alternative to pharmacological treatment or other conservative management, thus increasing access to care.

The role of ultrasound imaging in urogynecology is not clearly defined. Despite significant developments in visualization techniques and interpretation of images, pelvic ultrasound is still more a tool for research than for clinical practice. Structures of the lower genitourinary tract and pelvic floor can be visualized from different approaches: transperineal, introital, transvaginal, abdominal or endoanal. According to contemporary guidelines and recommendations, the role of ultrasound in urogynecology is limited to the measurement of post-void residue. However, in many instances, including planning and audit of surgical procedures, management of recurrences or complications, ultrasound may be proposed as the initial examination of choice. Ultrasound may be used for assessment of bladder neck mobility before anti-incontinence procedures. On rare occasions it is helpful in recognition of pathologies mimicking vaginal prolapse such as vaginal cyst, urethral diverticula or rectal intussusception. In patients subjected to suburethral slings, causes of surgery failure or postsurgical voiding dysfunctions can be revealed by imaging. Many reports link the location of a tape close to the bladder neck to unfavorable outcomes of sling surgery. Some postoperative complications, such as urinary retention, mesh malposition, hematoma, or urinary tract injury, can be diagnosed by ultrasound. On the other hand, the clinical value of some applications of ultrasound in urogynecology, for example measurement of the bladder wall thickness as a marker of detrusor overactivity, has not been proved.

Methods: We retrospectively analyzed medical records of all patients with low rectal cancer who underwent the ELAPE procedure using biological mesh for perineal repair at the Gastrointestinal Surgery of Nanjing Drum Power Hospital between January 2013 and September 2015. All patients were closely followed up to now. Results: A total of 17 patients underwent ELAPE for low rectal cancer was screened. Of these, 15 patients had primary rectal cancer, 1 had local recurrent rectal cancer, and 1 had malignant melanoma. All patients underwent ELAPE successfully without intestinal perforation and got stage I healing in perineum wound without incision infection, dehiscence, cystocele perinealis, urethral dysfunction or intestinal obstruction. Perineum wound hematoma developed in just one patient and had successful percutaneous drainage in one week. During the follow-up, there was no recurrence, perineal hernia, sexual dysfunction, urinary retention, or bowel obstruction. Two patients described slight pain in the sacrococcygeal region without special handling. Conclusion: ELAPE is applicable to low rectal cancer. Biological mesh reconstruction of perineal defect seems to be safe and effective, with high patient compliance.

OBJECTIVE: To investigate the performance of MR-defecography (MRD) in lateral body position as an alternative to supine position. METHODS: 22 consecutive patients (16 females; mean age 51 ± 19.4) with obstructed defecation and 20 healthy volunteers (11 females; mean age 33.4 ± 11.5) underwent MRD in a closed-configuration 3T-MRI in supine and lateral position. MRD included T(2) weighted images at rest and during defecation after filling the rectum with 250 ml water-based gel. Measurements were performed in reference to the pubococcygeal line and grade of evacuation was assessed. Image quality (IQ) was rated on a 5-point-scale (5 = excellent). RESULTS: In patients grades of middle and posterior compartment descent were similar in both body positions (p > 0.05). Grades of anterior compartment descent were significantly higher in lateral position (21/22 vs 17/22 patients with normal or small descent, p < 0.034). In volunteers grades of descent were similar for all compartments in supine and lateral position (p > 0.05). When attempting to defecate in supine position 6/22 (27%) patients showed no evacuation, while in lateral position only 3/22 (14%) were not able to evacuate. IQ in patients was equal at rest (4.4 ± 0.5 and 4.7 ± 0.6, p > 0.05) and slightly better in supine compared to the lateral position during defecation (4.5 ± 0.4 vs 3.9 ± 0.9, p < 0.017). IQ in volunteers was equal in supine and lateral position (p > 0.05). CONCLUSION: In lateral position, more patients were able to evacuate with similar grades of pelvic floor descent compared to supine position. MRD in lateral position may be a valuable alternative for patients unable to defecate in supine position. ADVANCES IN KNOWLEDGE: In lateral position, more patients were able to evacuate during MRD. MRD in lateral position may be an alternative for patients unable to defecate in supine position.

Aim: To evaluate the efficacy of early duloxetine therapy in stress urinary incontinence occurring after radical prostatectomy (RP). Material and Method: Patients that had RP were randomly divided into 2 groups following the removal of the urinary catheter. Group A patients (n = 28) had pelvic floor exercise and duloxetine therapy. Group B patients (n = 30) had only pelvic floor exercise. The incontinence status of the patients and number of pads were recorded and 1-hour pad test and Turkish validation of International Consultation on Incontinence Questionnaire-Short Form test were applied to the patients at the follow-up. Results: When the dry state of the patients was evaluated, 5, 17, 3, and 2 of 28 Group A patients stated that they were completely dry in the 3rd, 6th, 9th and 12th month respectively and pad use was stopped. There was no continence in 30 Group B in the first 3 months. Twelve, 6, and 8 patients stated that they were completely dry in the 6th, 9th and 12th month, respectively. But 3 of 4 patients in whom dryness could not be provided were using a mean of 7.6 pads in the first day and a mean of 1.3 pads after 1 year. When pad use of the patients was evaluated, the mean monthly number of pad use was determined to be 6.2 (4-8) in the initial evaluation, 2.7 (0-5) in the in 3rd month, 2 (0-3) in the 6th month and 1.6 (0-2) pad/d in the 9th month in the group taking medicine. The mean monthly number of pads used was determined to be 5.8 (4-8) in the initial evaluation, 4.3 (3-8) in the 3rd month, 3 (0-6) in the 6th month and 1.6 (0-6) pad/d in the 9th month in the group not taking medicine. Conclusion: According to the results, early duloxetine therapy in stress urinary incontinence that occurred after RP provided early continence.

Because levator ani (LA) muscle injuries occur in approximately 13% of all vaginal births, insights are needed to better prevent them. In Part I of this paper, we conducted an analysis of the bony and soft tissue factors contributing to the geometric “capacity” of the maternal pelvis and pelvic floor to deliver a fetal head without incurring stretch injury of the maternal soft tissue. In Part II, we quantified the range in demand, represented by the variation in fetal head size and shape, placed on the maternal pelvic floor. In Part III, we analyzed the capacity-to-demand geometric ratio, g, in order to determine whether a mother can deliver a head of given size without stretch injury. The results of a Part I sensitivity analysis showed that initial soft tissue loop length (SL) had the greatest effect on maternal capacity, followed by the length of the soft tissue loop above the inferior pubic rami at ultimate crowning, then subpubic arch angle (SPAA) and head size, and finally the levator origin separation distance. We found the more caudal origin of the puborectal portion of the levator muscle helps to protect it from the stretch injuries commonly observed in the pubovisceral portion. Part II fetal head molding index (MI) and fetal head size revealed fetal head circumference values ranging from 253 to 351 mm, which would increase up to 11 mm upon face presentation. The Part III capacity-demand analysis of g revealed that, based on geometry alone, the 10th percentile maternal capacity predicted injury for all head sizes, the 25th percentile maternal capacity could deliver half of all head sizes, while the 50th percentile maternal capacity could deliver a head of any size without injury. If ultrasound imaging could be operationalized to make measurements of ratio g, it might be used to usefully inform women on their level of risk for levator injury during vaginal birth.

Objective: To evaluate the use of palpation of the coccyx (the coccygeal movement test, CMT) as a possible objective screening tool for the assessment of adequate localization of the pelvic floor muscles (PFMs). Subjects and Methods: Twenty-four healthy female volunteers, known to be able to locate their PFMs, were given instructions (allocated at random) to perform a ‘correct contraction', ‘straining' or ‘nothing' when examined by six independent assessors using the CMT. The assessors were blinded to the instructions and to the test results recorded by other assessors. Data were available for 137 observations, and these were dichotomized into either ‘able to contract' (‘correct contraction') or ‘not able to contract' (‘straining' or ‘nothing'). This information was used to calculate the sensitivity, specificity and positive and negative predictive values for the CMT. Results: The CMT correctly identified 56/58 observations when women did not perform the contraction of the PFMs compared to 61/79 observations when they did. Hence, the sensitivity and specificity were 97 and 77%, respectively. Conclusion: This study showed that the CMT was a useful test to identify women who were able to localize their PFMs compared to those who were not, making it a potentially useful initial screening test in structured training programmes for the PFMs.

Several key steps essential for the reduction of vaginal prolapse in patients undergoing laparoscopic hysterectomy are reported., Background and Objectives: Today, laparoscopic intrafascial hysterectomy and laparoscopic supracervical hysterectomy are well-accepted techniques. With our multimodal concept of laparoscopic hysterectomy for benign indications, preservation of the pelvic floor as well as reconstruction of pelvic floor structures and pre-existing prolapse situations can be achieved. Methods: The multimodal concept consists of 3 steps: Intrafascial hysterectomy with preservation of existing structures Technique 1: Primary uterine artery ligationTechnique 2: Classic intrafascial hysterectomyA technique for the stable fixation of the vaginal or cervical stumpA new method of pectopexy to correct a pre-existing descensus situation Results and Conclustion: This well-balanced concept can be used by advanced endoscopic gynecologic surgeons as well as by novices in our field.

This study investigated the morphology and structure of pelvic floor in 50 nulliparous and 95 postpartum women (47 vaginal delivery, 48 Cesarean section) using translabial three-dimensional (3D) ultrasound. All the primiparae underwent ultrasound examination within one week after their first delivery. Volume datasets were acquired and analyzed to determine the alterations of levator hiatus after childbirth. Significant differences were observed in the levator hiatus of postpartum women compared with that of nullipara women. In postpartum women, the levator hiatus, with their dimensions increased, expanded into a circular shape. Puborectalis was avulsed in eight cases (accounting for 8.42% of all) and pelvic organ prolapse was found in 12 cases (accounting for 12.63%). The hiatal dimensions were larger and the incidence of pubrectalis muscle avulsion (17.02% vs. 0%) and pelvic organ prolapse (21.28% vs. 4.17%) was significantly higher in Vaginal delivery group than Cesarean section group. In summary, 3D ultrasound is an effective tool to detect the pelvic floor of postpartum women who present with morphological abnormalities, and such abnormalities are more likely to show in vaginal delivery women compared to Cesarean section.

The frequency of female pelvic floor reconstruction surgery with synthetic materials has been systematically rising for the last 30 years. Nowadays, they are widely used in urogynecology with a high cure rate, and a statistically significant better outcome compared to classical vaginal repair procedures. This type of operation progressed in some areas from an indication for recurrent prolapse to that of using them in primary procedures. Nevertheless, implantation of synthetic material is associated with the occurrence of specific complications and side-effects. The number and type of complications varies, depending on the study, reaching as much as 10% in some centers. The International Continence Society (ICS) and International Urogynecological Association (IUGA) have introduced an interesting tool for the evaluation of complications related directly to the insertion of prostheses and grafts in the female pelvic floor. The purpose of this classification is to describe possible complications with numbers and letters which together form a code containing comprehensive information about the complication. This article presents the clinical and practical aspects of this classification and first comments about its usability. The presented classification may serve as a tool for the development of national and international registries of urogynecological procedures that would be a great source of information on the number and type of operations performed, their effectiveness and potential complications.

Objectives We present a new surgery based on the round ligament anatomy that is called laparoscopic abdominopexy, which uses a synthetic mesh without fixation at any pelvic point. The aim of this study is to provide a step-by-step description of the laparoscopic abdominopexy technique and present the first anatomical and functional results of the procedure. Methods This prospective cohort study included patients with apical and anterior vaginal prolapse who were subjected to laparoscopic abdominopexy. Before and after surgery, the Pelvic Organ Prolapse Quantification (POP-Q) scale, Overactive Bladder Questionnaire-Short Form (OABq-SF), and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) were used to evaluate the vaginal prolapse stage, storage, and sexual symptoms, respectively. The surgical technique is described step by step. Results Twenty patients were included with follow-up times between 6 and 25 months. The mean surgical time was 78.4 minutes. A statistically significant improvement was observed in the Aa (P ≤ 10-5), Ba (P ≤ 10-5), C (P = 5 × 10-5), D (P = .002) and tvl (P = .02) POP-Q points and in OABq-SF (22.2%; P = .02). Successful surgery was observed in 100% of patients for the apical compartment and 90% of patients for the anterior compartment. Conclusion Laparoscopic abdominopexy is a quick, safe, and reproducible surgical technique with beneficial anatomical and functional results that preserve the pelvic floor anatomy.

The objective of this study was to evaluate the morphological and immunohistochemical alterations of tissue removed from the upper third of anterior vaginal wall in a sample group of the female population presenting homogenous risk factors associated with Pelvic Organ Prolapse (POP). The case study consisted of 14 patients with POP and there were 10 patients in the control group. Patient selection was carried on the basis of specific criteria and all of the patients involved in the study presented one or more of the recognized POP risk factors. Samples were taken from POP patients during vaginal plastic surgery following colpohysterectomy, and from control patients during closure of the posterior fornix following hysterectomy. Samples were processed for histological and immunohistochemical analyses for Collagen I and Collagen III, α-Smooth Muscle Actin (α-SMA), Platelet-Derived-Growth-Factor (PDGF), matrix metalloproteinase 3 (MMP3), Caspase3. Immunofluorescence analyses for Collagen I and III and PDGF were also carried out. In prolapsed specimens our results show a disorganization of smooth muscle cells that appeared to have been displaced by an increased collagen III deposition resulting in rearrangement of the muscularis propria architecture. These findings suggest that the increase in the expression of collagen fibers in muscularis could probably due to a phenotypic switch resulting in the dedifferentiation of smooth muscle cells into myofibroblasts. These alterations could be responsible for the compromising of the dynamic functionality of the pelvic floor.

The present study investigated the morphology and structure of pelvic floor in 50 nulliparous and 50 pelvic organ prolapse (POP) women using translabial three-dimensional (3D) ultrasound. The levator hiatus in POP women was significantly different from that in nullipara women. In POP women, the size of pelvic floor increased, with a circular shape, and the axis of levator hiatus departed from the normal position in 36 (72%) cases. The puborectalis was avulsed in 18 (36%) cases and the pelvic organs arranged abnormally in 23 (46%) cases. In summary, 3D ultrasound is an effective tool to detect the pelvic floor in POP women who presented with abnormalities in the morphology and structure of pelvic floor.

Incontinent women have low rates of care seeking and treatment, some of which may be explained by their beliefs about the causes of their own urine loss. As little is known about these beliefs, our aim was to qualitatively assess what women perceive as the etiology of their urinary incontinence (UI).In a written survey on urinary symptoms administered to female HMO enrollees aged 30-90 years, incontinent women were asked the open-ended question: "Why do you think you lose urine?" Qualitative analyses of the responses identified themes, which were quantified and organized into major categories. Subjects were assigned multiple themes/categories as indicated. Relationships between major categories and subject/incontinence characteristics were explored.Of the 1458 women with incontinence who completed the survey, 1192 (82%) responded to the open-ended question. Qualitative analyses identified 23 themes, with 5 themes cited byor=10% of subjects: pelvic floor/bladder muscles (31%), pregnancy/childbirth (18%), age (14%), exertional triggers (12%), and waiting too long to void (10%). The 23 themes were organized into 5 major categories: pelvic floor/bladder related (53%), uncontrollable factors (23%), part of being female (21%), personal/lifestyle attributes (21%), and don't know (12%). Subjects expressed a range of 1-4 themes/categories. Major categories differed by age, and significant associations were seen between major categories and incontinence severity.Women attribute their UI to a number of causes, which can be condensed into workable themes and categories. By understanding women's beliefs about the etiology of incontinence, clinicians may improve their ability to educate, counsel, and treat women with incontinence.

Objectives To determine the feasibility and acceptability of traditional Chinese medicine (TCM) acupuncture and pelvic floor muscle training (PFMT) in reducing symptoms and bothersomeness in women with mixed urinary incontinence (MUI); and to estimate the sample size for a full scale trial. Methods Thirty-four women with MUI were randomly assigned to either 12 sessions of TCM acupuncture, 12 sessions of PFMT, or to a waiting list control group. Outcome measures included an assessment of interest to participate in the trial, identification of successful recruitment strategies, the appropriateness of eligibility criteria, and compliance with treatment. Clinical outcomes were assessed at baseline and 12 weeks, and included the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI SF), expectations of treatment effect, and adverse events. Results Recruitment was feasible and randomisation worked adequately by means of SurveyMonkey. SurveyMonkey does not permit stratification by ICIQ-UI SF baseline score. Fourteen of 22 women found the treatment options acceptable. The dropout rate was high, especially in the control group (6/12). Outcome forms were completed by 20 of 34 women. The median (IQR) changes of the ICIQ-UI SF scores in the acupuncture, physiotherapy, and waiting list group were 5.5 (2.3 to 6.8), 1.0 (−3.0 to 4.5), and 1.5 (−1.5 to 3.0), respectively, suggesting the need for a full scale trial. Conclusions Women with MUI were willing to participate in this study. There is a need for adjusting eligibility criteria. A sample size of 129 women, 43 in three arms, is required. No major adverse events occurred.

Pelvic floor disorders, a group of conditions affecting adult women, include pelvic organ prolapse and urinary incontinence. Vaginal childbirth and aging are risk factors, and weakening of the pelvic support structures is a major aspect of the pathology. However, the underlying molecular mechanism remains unknown. Female reproductive organs are rich in elastic fibers that turn over slowly in most adult tissues but undergo massive remodeling in the reproductive organs through pregnancy and birth. Here we show that a failure to maintain elastic fiber homeostasis in mice causes pelvic floor disorders. Lysyl oxidase-like-1 (LOXL1), a protein essential for the postnatal deposition of elastic fibers, was highly expressed and regulated in the reproductive tract of the mouse, and its expression was diminished during aging. LOXL1 deficiency caused an inability of reproductive tissues to replenish elastic fibers after parturition, leading to pelvic organ prolapse, weakening of the vaginal wall, paraurethral pathology, and lower urinary tract dysfunction. These data demonstrate the importance of elastic fibers for maintaining structural and functional integrity of the female pelvic floor. Our findings raise the possibility that a failure of elastic fiber homeostasis, either due to genetic predisposition or advancing age, could underlie the etiology of pelvic floor dysfunction in women.

Pelvic floor dysfunction has resulted in 11% of American women undergoing surgery during their lifespan [1]. Over 200,000 prolapse operations are performed each year; this is as many as for breast cancer and more than twice as many as for prostate cancer [2]. The annual estimated cost for prolapse surgery exceeds US $1 billion [3]. Pelvic organ support involves the dynamic interaction between support provided by the levator ani muscles and the connective tissues that attach the organs to the pelvic walls [4]. Vaginal birth can damage those muscles (e.g., Ref. [5]), and it has been noted that pelvic organ prolapse typically occurs in women 20–30 years after having delivered children vaginally [6]. It is possible that repetitive loading and age-related deterioration of the connective tissues loaded over that time might contribute to the subsequent failure. Although subject to debate, many clinicians will support the fact that most women complain of worsening prolapse symptoms at the end of an active day [7]. Therefore, it is important to understand the material properties of the connective tissue in a time- and load history-dependent mechanical setting. This can help us better understand risk factors for prolapse, such as in women who perform repetitive heavy lifting, the effect of the second stage of labor, as well as the fact that pelvic organ prolapse develops rather late in a woman's life and is likely multifactorial in nature. The uterine suspensory tissue, comprised of the cardinal and uterosacral ligaments, is thought to play an important role in resisting pelvic organ prolapse [8]. The CL and USL constitute part of the level I support for the pelvic floor [9]. The CL originates from the pelvic side wall at the top of the greater sciatic foramen to its insertion on the genital tract, centered on the cervix and upper vagina [10]. The USL originates from sacrum and sacrospinous ligament-coccygeus muscle and inserts on the genital tract [10]. There are four ligament structures in total: one CL and one USL on either side of the uterus (Fig. ​(Fig.11). Fig. 1 Anatomy of female uterine suspensory tissue in a 3D model based on MRI of a healthy control.
