RESUMO
Exceptional points (EPs) in the polarization space were observed in reflection on helically structured thin films. These films have form anisotropy at the nanoscale introduced through dynamic control of crystalline growth geometry by changing the orientation of the substrate with respect to the impinging vapor. They are simpler alternatives to metasurfaces, because they can be produced at low cost using conventional thin-film deposition techniques. The EPs were experimentally confirmed by eigenstate swapping on a closed circuit surrounding them and were predicted by numerical calculations. Reflective surfaces operating at an EP could be used to make ultrasensitive sensors.
RESUMO
AIMS: We aimed to assess the value of the Valsalva urethral profile (VUP) in case of stress urinary incontinence (SUI). METHODS: Six hundred and ninety-four women without pelvic organ prolapse were included in this prospective monocentric study. SUI was diagnosed from symptoms using the International Continence Society definition, and severity using two validated questionnaires (USP and ICIQ-SF). The urodynamic parameters studied were maximal urethral closure pressure (MUCP) and functional length (FL). Both were performed at rest, during a Valsalva maneuver (v-MUCP and v-FL) and again at rest. Correlation analyses and ROC curves were used to assess the value of the clinical and urodynamic measurements. RESULTS: In our population, based on the questionnaires, 172 (24.8%) women were diagnosed with pure SUI on symptoms, 71 (10.2%) with urgency urinary incontinence and 392 (56.5%) with mixed urinary incontinence; 59 (8.5%) women were continent. The v-MUCP was the most correlated parameter to the severity of SUI (ρ: -0.63) and the most predictive of SUI risk, with a threshold value of 35 cm H2 O (Se = 0.82, Sp = 0.86). The v-FL was significantly shortened in case of SUI. CONCLUSIONS: The v-MUCP and v-FL are global measurements of urethral resistance during stress. With a threshold value of 35 cm H2 O, the v-MUCP was the most discriminating parameter for the diagnosis of SUI, with a good reliability.

INTRODUCTION AND HYPOTHESIS: We aimed to evaluate the medium-term results of laparoscopic sacropexy (LSP) with validated self-administered questionnaires of symptoms and quality of life and to identify pre-, intra-, and postoperative predictors of postoperative dissatisfaction. METHODS: The study included 152 women who had LSP for stage 2 or higher pelvic organ prolapse (POP). The study population comprised women who had completed the preoperative symptom questionnaire (including the PFDI-20 and ICIQ-SF). Postoperative questionnaires included those questionnaires as well as the PFIQ-7 and EQ-5D questionnaires, PISQ-12 sexual function questionnaire, and PGI-I questionnaire (to assess patient satisfaction). RESULTS: In all, 92 women (60.5%) responded in the postoperative period; 75 (81.5%) had anterior and posterior mesh and 17 (18.5%) anterior mesh alone. Moreover, 14 women (15.2%) had a concomitant suburethral sling and 18 (19.6%) a concomitant subtotal hysterectomy. The mean follow-up time was 50.5 (± 20.3) months (4.2 years). PFDI-20 scores had improved significantly at 4 years (median: 47.4 before surgery vs. 34.4 afterwards, p = 0.002), and patient satisfaction was quite clear (PGI-I score = 1.8 ± 1.1). Nine women (9.8%) described recurring vaginal bulge symptoms, and 12 patients were reoperated during follow-up. Recurrence [odds ratio (OR) 8.11, 95% confidence interval (95% CI) 2.28-28.9] and postoperative constipation (OR = 3.47, 95% CI 1.02-11.8) were strongly associated with poorer postoperative satisfaction, as was concomitant UI surgery (OR = 12.5, 95% CI 2.32-67.0). CONCLUSIONS: LSP improved women's symptoms and quality of life. Postoperative constipation, sensation of prolapse recurrence, and concomitant UI surgery were strongly associated with postoperative dissatisfaction.

INTRODUCTION AND HYPOTHESIS: Ultrasound measurement of urethral mobility is an attractive approach to directly visualize bladder neck descent (BND) during stress. BND assessed by transperineal ultrasound appears to be associated with stress urinary incontinence (SUI) severity. This study evaluated the inter- and intra-observer reliability of ultrasound BND measurement and its correlation with clinical examination. METHODS: We included 50 women from the multicenter randomized 3PN study ("Prenatal Perineal Prevention"). BND was measured by two operators either during pregnancy (at 20 weeks of gestation) or 2 months after delivery. Two measurements were taken by each operator. Intra-class coefficient correlations were used for analysis. Urethral mobility was clinically assessed by measuring the point Aa of the POP-Q classification during maximum strain (Valsalva maneuver) with an empty bladder. RESULTS: Ultrasound analysis showed high intra-observer reliability in the overall population: intraclass correlation coefficients (ICC) = 0.75 (0.59-0.85) and 0.73 (0.55-0.84) for each operator. Intra-observer agreements were considered moderate to high in the post- and antepartum groups. Inter-observer agreements were moderate in the antepartum period [ICC = 0.58 (0.26-0.78) for the first measurement and 0.68 (0.42-0.84) for the second] but low in the postpartum period [ICC = 0.15 (0.10-0.41) and 0.21 (0.10-0.58)]. Correlations between ultrasound and clinical measurements were considered low to moderate (Spearman coefficient, rho = 0.34 and 0.50 for post- and antepartum periods, respectively). CONCLUSIONS: Inter-observer reliability of ultrasound urethral mobility measurements by the transperineal route is moderate antepartum and low postpartum. The correlation with point Aa is low to moderate.

Importance: Safety of hysteroscopic sterilization has been recently questioned following reports of general symptoms such as allergy, tiredness, and depression in addition to associated gynecological results such as pelvic pain, perforation of fallopian tubes or uterus, and unwanted pregnancy. Objective: To compare the risk of reported adverse events between hysteroscopic and laparoscopic sterilization. Design, Setting, and Participants: French nationwide cohort study using the national hospital discharge database linked to the health insurance claims database. Women aged 30 to 54 years receiving a first hysteroscopic or laparoscopic sterilization between 2010 and 2014 were included and were followed up through December 2015. Exposures: Hysteroscopic sterilization vs laparoscopic sterilization. Main Outcomes and Measures: Risks of procedural complications (surgical and medical) and of gynecological (sterilization failure that includes salpingectomy, second sterilization procedure, or pregnancy; pregnancy; reoperation) and medical outcomes (all types of allergy; autoimmune diseases; thyroid disorder; use of analgesics, antimigraines, antidepressants, benzodiazepines; outpatient visits; sickness absence; suicide attempts; death) that occurred within 1 and 3 years after sterilization were compared using inverse probability of treatment-weighted Cox models. Results: Of the 105â¯357 women included (95.5% of eligible participants; mean age, 41.3 years [SD, 3.7 years]), 71â¯303 (67.7% ) underwent hysteroscopic sterilization, and 34â¯054 (32.3%) underwent laparoscopic sterilization. During the hospitalization for sterilization, risk of surgical complications for hysteroscopic sterilization was lower: 0.13% for hysteroscopic sterilization vs 0.78% for laparoscopic sterilization (adjusted risk difference [RD], -0.64; 95% CI, -0.67 to -0.60) and was lower for medical complications: 0.06% vs 0.11% (adjusted RD, -0.05; 95% CI, -0.08 to -0.01). During the first year after sterilization, 4.83% of women who underwent hysteroscopic sterilization had a higher risk of sterilization failure than the 0.69% who underwent laparoscopic sterilization (adjusted hazard ratio [HR], 7.11; 95% CI, 5.92 to 8.54; adjusted RD, 4.23 per 100 person-years; 95% CI, 3.40 to 5.22). Additionally, 5.65% of women who underwent hysteroscopic sterilization required gynecological reoperation vs 1.76% of women who underwent laparoscopic sterilization (adjusted HR, 3.26; 95% CI, 2.90 to 3.67; adjusted RD, 4.63 per 100 person-years; 95% CI, 3.38 to 4.75); these differences persisted after 3 years, although attenuated. Hysteroscopic sterilization was associated with a lower risk of pregnancy within the first year of the procedure but was not significantly associated with a difference in risk of pregnancy by the third year (adjusted HR, 1.04; 95% CI, 0.83-1.30; adjusted RD, 0.01 per 100 person-years; 95% CI, -0.04 to 0.07). Risks of medical outcomes were not significantly increased with hysteroscopic sterilization compared with laparoscopic sterilization. Conclusions and Relevance: Among women undergoing first sterilization, the use of hysteroscopic sterilization was significantly associated with higher risk of gynecological complications over 1 year and over 3 years than was laparoscopic sterilization. Risk of medical outcomes was not significantly increased over 1 year or over 3 years. These findings do not support increased medical risks associated with hysteroscopic sterilization.

INTRODUCTION AND HYPOTHESIS: Obstetric trauma during childbirth is considered a major risk factor for postpartum urinary incontinence (UI), particularly stress urinary incontinence. Our aim was to investigate the relation between postpartum UI, mode of delivery, and urethral descent, and to define a group of women who are particularly at risk of postnatal UI. METHODS: A total of 186 women were included their first pregnancy. Validated questionnaires about urinary symptoms during pregnancy, 2 and 12 months after delivery, were administered. Urethral descent was assessed clinically and by ultrasound at inclusion. Multivariate logistic regression analysis was used to determine the risk factors for UI during pregnancy, at 2 months and 1 year after first delivery. RESULTS: The prevalence of UI was 38.6, 46.5, 35.6, and 34.4 % at inclusion, late pregnancy, 2 months postpartum, and 1 year postpartum respectively. No significant association was found between UI at late pregnancy and urethral descent assessed clinically or by ultrasound. The only risk factor for UI at 2 months postpartum was UI at inclusion (OR 6.27 [95 % CI 2.70-14.6]). The risk factors for UI at 1 year postpartum were UI at inclusion (6.14 [2.22-16.9]), body mass index (BMI), and urethral descent at inclusion, assessed clinically (7.21 [2.20-23.7]) or by ultrasound. The mode of delivery was not associated with urethral descent. CONCLUSIONS: Prenatal urethral descent and UI during pregnancy are risk factors for UI at 1 year postpartum. These results indicate that postnatal UI is more strongly influenced by susceptibility factors existing before first delivery than by the mode of delivery.

Single-material interference filters are obtained from magnetron sputtered alternating layers of WO3 deposited at different pressures. The stop band is investigated with respect to the refractive index contrast and the total number of layers. Some features of rugate filters are also investigated. We show experimentally that a sine-wave index profile modulation can be used to suppress the harmonic stop bands located at odd fractional wavelengths. We also show experimental evidence that sidelobes near the stop band can be attenuated by using a sine-wave index profile that has a variable amplitude.
RESUMO
Women's preoperative perceptions of pelvic-floor disorders may differ from those of their physicians. Our objective was to specify women's hopes and fears before cystocele repair, and to compare them to those that surgeons anticipate. We performed a secondary qualitative analysis of data from the PROSPERE trial. Among the 265 women included, 98% reported at least one hope and 86% one fear before surgery. Sixteen surgeons also completed the free expectations-questionnaire as a typical patient would. Women's hopes covered seven themes, and women's fears eleven. Women's hopes were concerning prolapse repair (60%), improvement of urinary function (39%), capacity for physical activities (28%), sexual function (27%), well-being (25%), and end of pain or heaviness (19%). Women's fears were concerning prolapse relapse (38%), perioperative concerns (28%), urinary disorders (26%), pain (19%), sexual problems (10%), and physical impairment (6%). Surgeons anticipated typical hopes and fears which were very similar to those the majority of women reported. However, only 60% of the women reported prolapse repair as an expectation. Women's expectations appear reasonable and consistent with the scientific literature on the improvement and the risk of relapse or complication related to cystocele repair. Our analysis encourages surgeons to consider individual woman's expectations before pelvic-floor repair.
RESUMO
BACKGROUND: Laparoscopic promontofixation is the gold standard to treat apical defects but the dissection of the anterior compartment is variable since based on surgical judgment only. We therefore evaluate the placement of the anterior mesh using an ultrasonographic measurement after promontofixation. DESIGN: A prospective cohort study (Canadian Task Force Classification II-1) was conducted between January 2015 and September 2015. 63 women that underwent a promontofixation for prolapse were included. Pelvic floor descent was evaluated with POP-Q. The distance between the bladder neck, and the anterior mesh was measured by ultrasound at the end of surgery. The placement of the mesh was subsequently correlated to the anatomical repair 1â¯month after surgery, and the occurrence of de novo symptoms as stress urinary incontinence. RESULTS: Ultrasound permitted to measure the distance between bladder neck and Mesh (BMDâ¯=â¯Bladder neck-Mesh Distance) in all patients with variation between repeated measurements ranging for 0.6 to 1.2â¯mm. The BMD was highly variable from 0 to 13â¯mm (mean⯱â¯SD; 5.3⯱â¯3.1â¯mm). The BMD inversely correlated with the difference between C (Pâ¯=â¯0.01) and Bp (Pâ¯=â¯0.04) after and before surgery respectively, with the complication rate (Pâ¯=â¯0.01) but not with the difference of Ba. A BMD of more than 6â¯mm predicted the absence of postoperative de novo symptoms. De novo" stress urinary incontinence occurred in 23.8%. CONCLUSION: BMD can be accurately measured by ultrasound. BMD predicts the apical repair but not the anterior repair. A short BMD predicted postoperative de novo stress urinary incontinence.

BACKGROUND: Laparoscopic mesh sacropexy (LS) or transvaginal mesh repair (TVM) are surgical techniques used to treat cystoceles. Health authorities have highlighted the need for comparative studies to evaluate the safety of surgeries with meshes. OBJECTIVE: To compare the rate of complications, and functional and anatomical outcomes between LS and TVM. DESIGN, SETTING, AND PARTICIPANTS: Multicenter randomized controlled trial from October 2012 to April 2014 in 11 French public hospitals. Women with cystocele stage ≥2 (pelvic organ prolapse quantification), aged 45-75 yr, without previous prolapse surgery. INTERVENTION: Synthetic nonabsorbable mesh placed in the vesicovaginal space, sutured to the promontory (LS) or maintained by arms through pelvic ligaments (TVM). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Rate of surgical complications ≥grade II according to the modified Clavien-Dindo classification at 1 yr. Secondary outcomes were reintervention rate, and functional and anatomical results. RESULTS AND LIMITATIONS: A total of 130 women were randomized in LS and 132 in TVM; five women withdrew before intervention, leaving 129 in LS and 128 in TVM. The rate of complications ≥grade II was lower after LS than after TVM, but did not meet statistical significance (17% vs 26%, treatment difference 8.6% [95% confidence interval, CI -1.5 to 18]; p=0.088). The rate of complications of grade III or higher was nonetheless significantly lower after LS (LS=0.8%, TVM=9.4%, treatment difference 8.6% [95% CI 3.4%; 15%]; p=0.001). LS was converted to TVM in 6.3%. The total reoperation rate was lower after LS but did not meet statistical significance (LS=4.7%, TVM=10.9%, treatment difference 6.3% [95% CI -0.4 to 13.3]; p=0.060). There was no difference in symptoms, quality of life, improvement, composite definition of success, anatomical results rates between groups except for the vaginal apex and length, and dyspareunia (in favor of LS). CONCLUSIONS: LS is a valuable option for primary repair of cystocele in sexually active patients. LS is safer than TVM, but may not be feasible in all cases. Both techniques offer same functional outcomes, success rates, and anatomical outcomes, but sexual function is better preserved by LS. PATIENT SUMMARY: Our study demonstrates that laparoscopic sacropexy (LS) is a valuable option for primary repair of cystocele. LS offers equivalent success rates to vaginal mesh procedures, but is safer with a lower rate of complications and reoperations, and sexual function is better preserved.

PURPOSE: Maintaining urinary continence at stress requires a competent urethral sphincter and good suburethral support. Sphincter competence is estimated by measuring the maximal urethral closure pressure at rest. We aimed to study the value of a new urodynamic measure, the urethral closure pressure at stress (s-UCP), in the diagnosis and severity of female stress urinary incontinence (SUI). METHODS: A total of 400 women without neurological disorders were included in this observational study. SUI was diagnosed using the International Continence Society definition, and severity was assessed using a validated French questionnaire, the Mesure du Handicap Urinaire. The perineal examination consisted of rating the strength of the levator ani muscle (0-5) and an assessment of bladder neck mobility using point Aa (cm). The urodynamic parameters were maximal urethral closure pressure at rest, s-UCP, Valsalva leak point pressure (cm H2O), and pressure transmission ratio (%). RESULTS: Of the women, 358 (89.5%) were diagnosed with SUI. The risk of SUI significantly increased as s-UCP decreased (odds ratio [OR], 0.92; 95% confidence interval, 0.88-0.98). The discriminative value of the measure was good for the diagnosis of SUI (area under curve>0.80). s-UCP values less than or equal to 20 cm H2O had a sensitivity of 73.1% and a specificity of 93.0% for predicting SUI. The association between s-UCP and SUI severity was also significant. CONCLUSIONS: s-UCP is the most discriminative measure that has been identified for the diagnosis of SUI. It is strongly inversely correlated with the severity of SUI. It appears to be a specific SUI biomarker reflecting both urethral sphincter competence and urethral support.
RESUMO
OBJECTIVE: To investigate if leakage circumstances collected using the Urinary Leakage Circumstances Questionnaire (ULCQ) are correlated with physician diagnosis and urodynamic results and resolve after surgery. MATERIALS AND METHODS: The ULCQ was developed to investigate leakage circumstances encountered by women with incontinence. Women completed both the ULCQ and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form before clinical and urodynamic examination. Those who underwent a suburethral sling procedure completed both questionnaires postoperatively. We performed a principal component analysis and evaluated the questionnaire's external properties including construct validity and responsiveness. RESULTS: One hundred and eighty-six women were included in the validation phase, and 168 underwent suburethral sling procedure. Mean postoperative follow-up was 51 months. Principal component analysis identified 4 dimensions from the 23 leakage circumstances listed in the ULCQ: effort, stimulation, postural, and intercourse; the internal consistency of each dimension was excellent (Cronbach alpha: 0.87, 0.86, 0.82, and 0.79, respectively). Effort (+0.39), stimulation (+0.24), and postural (+0.47) dimensions were correlated with the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form score; the effort dimension was correlated with greater stress incontinence severity assessed by the physician; the stimulation dimension with urgency and urge incontinence severity assessed by the physician, and with lower volumes during cystometry; and the postural dimension with higher age and lower urethral closure pressure. Each dimension recorded a significant improvement after surgery, with the largest effect size for effort dimension (2.29 [confidence interval 95%: 1.96-2.62]). CONCLUSION: The ULCQ is a useful tool for investigating female urinary incontinence and detecting changes after surgery.

PURPOSE: To map the vascular anatomy of the obturator foramen using fixed anatomic landmarks. METHOD: Twenty obturator regions were dissected in 10 fresh female cadavers after vascular blue dye injection in five cadavers (50%). Furthermore, 104 obturator regions were reconstructed by angiotomodensitometry from 52 women under investigation for suspected arterial disease. The anatomy of the obturator region was mapped by measuring the distance of vascular structures from the middle of the two branches of the ischiopubic bone, which were used as fixed landmarks. RESULTS: The bifurcation of the obturator artery was at a mean (SD) distance of 30.0 mm (4.5) from the middle of the ischiopubic branch (MISP). The anterior branch of the obturator vessels was 15.2 mm (10.1) from the MISP. The posterior branch of the obturator vessels was 5.5 mm (4.0) and 23.6 mm (8.7) from the middle of the outer edge of the obturator foramen (MOE) and the MISP, respectively. Using 5° and 95° percentiles of these measurements we defined a central avascular triangle. CONCLUSIONS: Our data show that, beyond inter-individual variations, a central triangular avascular area can be identified in the obturator foramen between the posterior and anterior obturator artery using fixed landmarks.

OBJECTIVE: To compare, in an unselected population of nulliparous pregnant women, the postnatal effect of prenatal supervised pelvic floor muscle training with written instructions on postpartum urinary incontinence (UI). METHODS: In a randomized controlled trial in two parallel groups, 282 women were recruited from five university teaching hospitals in France and randomized during the second trimester of pregnancy. The physiotherapy group received prenatal individually supervised exercises. Both groups received written instructions about how to perform exercises at home. Women were blindly assessed at baseline, end of pregnancy, and 2 and 12 months postpartum. The primary outcome measured was UI severity, assessed with an International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form score (range 0-21; 1-5 is slight UI) at 12 months postpartum; other outcomes were UI prevalence and pelvic floor troubles assessed using self-administered questionnaires. To give a 1-point difference in UI severity score, we needed 91 women in each group (standard deviation 2.4, α=0.05, ß=0.20, and bilateral analysis). RESULTS: Between February 2008 and June 2010, 140 women were randomized in the physiotherapy group and 142 in the control group. No difference was observed between the two groups in UI severity, prevalence, or pelvic floor troubles at baseline, end of pregnancy, and at 2 and 12 months postpartum. At 12 months postpartum, the primary outcome was available for 190 women (67.4%); mean UI severity was 1.9 in the physiotherapy group compared with 2.1 in the control group (P=.38). CONCLUSION: Prenatal supervised pelvic floor training was not superior to written instructions in reducing postnatal UI.

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.

BACKGROUND: Natural orifice translumenal endoscopic surgery is an emerging surgical phenomenon. Although the development of "pure" natural orifice translumenal endoscopic surgical techniques in humans has been slowed by major technical hurdles, "hybrid" or combined variants have been increasingly reported. Laparoscopic sleeve gastrectomy (SG) is a commonly performed treatment of morbid obesity. We have developed a combined variant of SG for patients with morbid obesity. Our aim was to assess the feasibility and safety of such an approach, which could eventually reduce the postoperative pain, preserve the abdominal wall, and enhance cosmesis. METHODS: Combined, transvaginal and abdominal SG was attempted in 20 patients. The inclusion criteria were morbid obesity (body mass index <50 kg/m(2)), female gender, an absence of gynecologic disorders, and the absence of major previous abdominal surgery. The local ethical committee approved the present study. The technique was performed using a vaginal incision with 1 or 2 abdominal ports. RESULTS: The procedure was a success in 14 patients (70%). In 6 patients, conversion to a more conventional laparoscopic SG was required, with ≥ 1 abdominal ports added. The mean operative time was 116 minutes (range 54-231). The postoperative complication rate was 5% (1 patient developed pneumonia). No hemorrhage, surgical site infection, or fistula was encountered. The mean length of hospital stay was 72 hours (range 24-144). CONCLUSION: Our combined, transvaginal and abdominal variant of laparoscopic SG was sure and feasible in a small series of selected patients with morbid obesity.

Epidermoid cysts are benign tumors that can develop in any part of the human body. Pelvic cysts adjacent to the rectum develop rarely, and few cases have been described in the literature. We report the case of a 58-year-old woman who underwent laparoscopic and perineal excision of a giant pararectal cyst that was discovered during laparoscopy performed for preoperative provisional diagnosis of an adnexal mass detected on an imaging study. To our knowledge, this is the second case of a pararectal cyst excised using combined laparoscopic and perineal approaches. In the hands of skilled laparoscopic surgeons, we suggest a combined laparoscopic and perineal approach for excision of giant pararectal cystic tumors to avert laparotomy.

Urinary incontinence is a frequent affliction in women and may be disabling and costly {LE1}. When consulting for urinary incontinence, it is recommended that circumstances, frequency and severity of leaks be specified {Grade B}. The cough test is recommended prior to surgery {Grade C}. Urodynamic investigations are not needed before lower urinary tract rehabilitation {Grade B}. A complete urodynamic investigation is recommended prior to surgery for urinary incontinence {Grade C}. In cases of pure stress urinary incontinence, urodynamic investigations are not essential prior to surgery provided the clinical assessment is fully comprehensive (standardised questionnaire, cough test, bladder diary, post-void residual volume) with concordant results {PC}. It is recommended to start treatment for stress incontinence with pelvic floor muscle training {Grade C}. Bladder training is recommended at first intention in cases with overactive bladder syndrome {Grade C}. For overweight patients, loss of weight improves stress incontinence {LE1}. For surgery, sub-urethral tape (retropubic or transobturator route) is the first-line recommended technique {Grade B}. Sub-urethral tape surgery involves intraoperative risks, postoperative risks and a risk of failure which must be the subject of prior information {Grade A}. Elective caesarean section and systematic episiotomy are not recommended methods of prevention for urinary incontinence {Grade B}. Pelvic floor muscle training is the treatment of first intention for pre- and postnatal urinary incontinence {Grade A}. Prior to any treatment for an elderly woman, it is recommended to screen for urinary infection using a test strip, ask for a bladder diary and measure post-void residual volume {Grade C}. It is recommended to carry out a cough test and look for occult incontinence prior to surgery for pelvic organ prolapse {Grade C}. It is recommended to carry out urodynamic investigations prior to pelvic organ prolapse surgery when there are urinary symptoms or occult urinary incontinence {Grade C}.

Trocar site hernia is a known complication after laparoscopic surgery, especially at 10-mm and larger port sites. Only a few cases of herniation through 5-mm port sites are reported in the literature. We describe 2 cases of bowel herniation and bowel obstruction through 5-mm port sites. The patients were 63 and 74 years old; both had endometrial cancer and underwent an uncomplicated hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy with peritoneal drains left at the lateral 5-mm port sites. Each patient presented symptoms of small bowel obstruction after which the drains were removed and were found to have evisceration through a laterally placed 5-mm port site. The bowel was reduced locally, and a segmental bowel resection was needed in 1 case. Bowel herniation can occur through the fascial defect after placement of a 5-mm port, especially if drains have been placed at the port site.

AIMS: To assess and compare the reliability of dynamic MRI to quantify pelvic organ prolapse (POP) according to the International Continence Society (ICS) using two different reference lines, and to determine which line gives the best concordance with clinical examination. METHODS: Forty-seven patients with genital prolapse underwent physical examination and dynamic MRI. Five nulliparous, symptom-free female volunteers underwent dynamic MRI as control subjects. Two distinct observers performed the MRI measurements of POP according to the ICS using two distinct reference lines: the mid-pubic line and a new one, the perineal line that provides a better match with the hymen plane. Measurements were repeated twice according to each line. The intra-class coefficient was used to estimate intra-observer and inter-observer reliability; the Altman and Bland plot was used to assess the agreement between MRI and clinical measurements. RESULTS: The intra-observer and inter-observer reliability of MRI measurements were in general excellent. Intra-class coefficients were better for the mid-pubic line than the perineal line. Although the MRI measurements correlate significantly with the physical measurements, the Altman and Bland plot shows an unacceptable magnitude of discrepancy between clinical and MRI examinations. CONCLUSIONS: Although dynamic MRI shows excellent inter- and intra-observer reliability, its agreement with clinical examination is poor whatever the line used.
