BJOG 2021; 129:1158-1164. [PMID: 34854216 DOI: 10.1111/1471-0528.17036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2021] [Revised: 10/01/2021] [Accepted: 10/31/2021] [Indexed: 11/27/2022]
Abstract
OBJECTIVE To develop and validate a prediction model for bothersome stress urinary incontinence after prolapse surgery and to compare it with an existing clinical prediction model (CUPIDO model). DESIGN Retrospective cohort study. SETTING Two tertiary hospitals in South Korea. POPULATION A total of 1142 patients who underwent prolapse surgery with or without a concomitant midurethral sling. METHODS To construct a prediction model, we performed logistic regression using both exhaustive and stepwise variable selection, validating the model both internally and externally. MAIN OUTCOME MEASURES Bothersome stress urinary incontinence defined as the presence of bothersome symptoms of stress urinary incontinence and/or subsequent continence procedure one year after surgery. RESULTS Postoperative bothersome stress urinary incontinence occurred in 10% of patients. A model containing six predictors (age, diabetes mellitus, subjective urinary incontinence, prolapse reduction stress test result, type of prolapse surgery, and a concomitant midurethral sling) showed excellent performance for predicting bothersome stress urinary incontinence (area under the curve 0.74, 95% confidence interval 0.62-0.86) and outperformed the CUPIDO model (area under the curve 0.63, 95% confidence interval 0.49-0.76; DeLong's test P = 0.014). CONCLUSIONS This prediction model might be a useful tool to guide patient decision making regarding a concomitant continence procedure at the time of prolapse surgery. The predictive value of this model needs to be validated further in cohorts with different characteristics. TWEETABLE ABSTRACT The proposed prediction model for bothersome stress urinary incontinence after prolapse surgery outperforms an existing model.

Abstract
AIM To determine the prevalence of stress urinary incontinence (SUI) and intrinsic sphincter deficiency (ISD) in women with stage IV pelvic organ prolapse. METHODS Retrospective analysis of women with stage IV prolapse who underwent multichannel urodynamic testing. Abdominal leak point pressures (ALPP) and maximum urethral closure pressures (MUCP) were recorded. ISD was defined as ALPP ≤60 cm of water and/or MUCP ≤20 cm of water. Percentages were used to present the proportion of subjects diagnosed with SUI and ISD. RESULTS A total of 145 patients met inclusion criteria. Mean age was 69 years; most patients were Caucasian (56%). Eighty-two (56%) patients were found to have SUI on urodynamic testing. Thirty-six (44%) of these were asymptomatic and identified as having occult SUI. Sixteen (19.5%) patients were diagnosed with ISD using ALPP and/or MUCP. Six (37%) of the ISD patients had at least one MUCP value ≤20 cm of water and 12 (75%) had observed leakage with at least one ALPP value ≤60 cm of water. The number of patients with leakage at ALPP ≤60 cm of water increased with increasing bladder volumes. Five ISD patients (31%) had ALPP ≤60 cm of water at 200 mL, six (37.5%) had ALPP ≤60 cm of water at 300 mL and seven (43.8%) had ALPP ≤60 cm of water at 400 mL. CONCLUSION Greater than 50% of patients with stage IV pelvic organ prolapse had SUI on urodynamic testing, and 20% were found to have ISD. Of the patients diagnosed with SUI, 40% were asymptomatic. These findings may assist in counseling and preoperative planning for women with stage IV prolapse.

Abstract
INTRODUCTION AND HYPOTHESIS There is no consensus for the evaluation of stress urinary incontinence (SUI) in patients planning pelvic organ prolapse (POP) surgery. We sought to determine the negative predictive value (NPV) of prolapse reduction during preoperative urodynamics (UDS) for postoperative SUI. METHODS We performed a retrospective study of 322 women with preoperative UDS and subsequent POP surgery. Abstracted data included demographics, prolapse stage, prior prolapse or incontinence surgery, preoperative SUI complaint, prolapse reduction method, and length of follow-up. Any woman who reported SUI symptoms within 6 months from surgery was considered a diagnostic UDS failure. The NPV was calculated by dividing the number of patients who did not demonstrate SUI on UDS and had no postoperative SUI by the number of patients who did not demonstrate SUI on UDS. RESULTS Patient characteristics (age, race, parity, prolapse stage, prior surgery, and length of follow-up) were similar among those who had urodynamic-proven SUI and those who did not. The NPV of preoperative UDS for postoperative SUI in patients undergoing any POP repair was 97.9.0% [95% confidence interval (CI) 92.7-99.7%]. The NPV remained high in the subset of patients who underwent an apical suspension-98.6% (95% CI 92.7-100.0%)-as well as those without a preoperative SUI complaint-98.6% (95% CI 92.3-100.0%). In most patients (72.9%), a ring pessary with support combined with intraprocedural manipulation allowed for reliable stress testing. CONCLUSIONS Our study supports using preoperative UDS as a screening tool to avoid unnecessary concomitant continence procedures. Further studies are needed to individualize patient preoperative assessment and surgical counseling.

Abstract
The evaluation of genital prolapse is essentially clinical; however imaging tests such as dynamic MRI or urodynamic explorations may be useful in complex cases, especially before surgical management. Dynamic MRI allows morphological and dynamic analysis of pelvic floor and levator ani function. It can also detect post-obstetric injuries, although the long-term significance of these injuries remains to be discovered. Quantification of the severity of prolapse is possible with MRI; however, the correlation of these measures with clinical examination seems poor. Its interest lies mainly in the qualitative assessment of the three stages of prolapse and the detection of elytroceles, which can be difficult to clinical examination. Urodynamics provides useful information on vesico-sphincteric function, but none of these parameters seems to be decisive in the management of prolapse.

Abstract
Surgery is often necessary after failure of conservative therapy for urinary incontinence. Guidelines recommend urodynamic studies before surgery. A distinction is made between non-invasive (uroflowmetry) and invasive methods (cystometry and pressure-flow study, if necessary as combined videourodynamics, as well as urethral pressure profile). All examinations serve to objectify and quantify the symptoms, to correctly assign symptoms to the pathophysiology and anatomy as well as to identify risk factors, which often have a significant influence on the success of surgical therapy. Given appropriate experience, complications and often significant sequelae of bladder dysfunction affecting the patient's quality of life and life expectancy can be recognized. Urodynamic studies are performed to help narrow down potential diagnoses, to develop therapeutic strategies, and to obtain prognostic parameters. The following article is intended to provide some support.

Abstract
INTRODUCTION The issue addressed in this chapter of recommendations is: What is the clinical and para-clinical assessment to achieve in women with genital prolapse and for whom surgical treatment has been decided. What are the clinical elements of the examination that must be taken into account as a risk factor of failure or relapse after surgery, in order to anticipate and evaluate possible surgical difficulties, and to move towards a preferred surgical technique? MATERIAL AND METHODS This work is based on a systematic review of the literature (PubMed, Medline, Cochrane Library, Cochrane Database of Systemactic Reviews, EMBASE) for meta-analyzes, randomized trials, registries, literature reviews, controlled studies and major not controlled studies, published on the subject. Its implementation has followed the methodology of the HAS on the recommendations for clinical practice, with a scientific argument (with the level of evidence, NP) and a recommendation grade (A, B, C, and professional agreement [AP]). RESULTS It suits first of all to describe prolapse, by clinical examination, helped, if needed, by a supplement of imagery if clinical examination data are insufficient or in case of discrepancy between the functional signs and clinical anomalies found, or in case of doubt in associated pathology. It suits to look relapse risk factors (high grade prolapse) and postoperative complications risk factors (risk factors for prothetic exposure, surgical approach difficulties, pelvic pain syndrome with hypersensitivity) to inform the patient and guide the therapeutic choice. Urinary functional disorders associated with prolapse (urinary incontinence, overactive bladder, dysuria, urinary tract infection, upper urinary tract impact) will be search and evaluated by interview and clinical examination and by a flowmeter with measurement of the post voiding residue, a urinalysis, and renal-bladder ultrasound. In the presence of voiding disorders, it is appropriate to do their clinical and urodynamic evaluation. In the absence of any spontaneous or hidden urinary sign, there is so far no reason to recommend systematically urodynamic assessment. Anorectal symptoms associated with prolapse (irritable bowel syndrome, obstruction of defecation, fecal incontinence) should be search and evaluated. Before prolapse surgery, it is essential not to ignore gynecologic pathology. CONCLUSION Before proposing a surgical cure of genital prolapse of women, it suits to achieve a clinical and paraclinical assessment to describe prolapse (anatomical structures involved, grade), to look for recurrence, difficulties approach and postoperative complications risk factors, and to appreciate the impact or the symptoms associated with prolapse (urinary, anorectal, gynecological, pelvic-perineal pain) to guide their evaluation and their treatment. © 2016 Published by Elsevier Masson SAS.

Abstract
AIMS The Blaivas-Groutz nomogram defines voiding obstruction in women using Qmax from the NIF and the maximum detrusor pressure (Pdetmax ) from the PFS. The aim of this study was to understand the relationship between NIF and PFS maximum flow rates in women with stress incontinence. METHODS We analyzed the UDS of 597 women with stress-dominant urinary incontinence. Each subject underwent a NIF and then a PFS. Mixed model was used to test the hypothesis that the relationship between flow rates and voided volume (VV) were similar for NIF and PFS. RESULTS There were 452 subjects with both NIF and PFS studies that met the inclusion criteria and had max flow rate (Qmax ) for both NIF and PFS. The mean age was 53. Overall, higher VV were observed during PFS compared to NIF and subjects had higher Qmax with NIF compared to PFS. The relationship between Qmax and VV was significantly different between NIF and PFS (P < 0.004). At 200 ml, NIF Qmax was 14% higher than PFS Qmax and this difference increased to 30% at 700 ml. CONCLUSION The difference between PFS Qmax and NIF Qmax increases as VV increase. As a result, values from PFS and NIF cannot be used interchangeably as has been suggested in the Blaivas-Groutz nomogram for obstruction in women.

Abstract
BACKGROUND Urodynamic tests are used to investigate people who have urinary incontinence or other urinary symptoms in order to make a definitive, objective diagnosis. The aim is to help select the treatment most likely to be successful. The investigations are invasive and time consuming. OBJECTIVES The objective of this review was to determine if treatment according to a urodynamic-based diagnosis, compared to treatment based on history and examination, led to more effective clinical care of people with urinary incontinence and better clinical outcomes.The intention was to test the following hypotheses in predefined subgroups of people with incontinence:(i) urodynamic investigations improve the clinical outcomes;(ii) urodynamic investigations alter clinical decision making;(iii) one type of urodynamic test is better than another in improving the outcomes of management of incontinence or influencing clinical decisions, or both. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and MEDLINE In-Process, handsearching of journals and conference proceedings (searched 19 February 2013), and the reference lists of relevant articles. SELECTION CRITERIA Randomised and quasi-randomised trials comparing clinical outcomes in groups of people who were and were not investigated using urodynamics, or comparing one type of urodynamic test against another were included. Trials were excluded if they did not report clinical outcomes. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. MAIN RESULTS Eight trials involving around 1100 people were included but data were only available for 1036 women in seven trials, of whom 526 received urodynamics. There was some evidence of risk of bias. The four deaths and 12 dropouts in the control arm of one trial were unexplained.There was significant evidence that the tests did change clinical decision making. Women in the urodynamic arms of three trials were more likely to have their management changed (proportion with change in management compared with the control arm 17% versus 3%, risk ratio (RR) 5.07, 95% CI 1.87 to 13.74), although there was statistical heterogeneity. There was evidence from two trials that women treated after urodynamic investigations were more likely to receive drugs (RR 2.09, 95% CI 1.32 to 3.31). On the other hand, in five trials women undergoing treatment following urodynamic investigation were not more likely to undergo surgery (RR 0.99, 95% CI 0.88 to 1.12).There was no statistically significant difference however in the number of women with urinary incontinence if they received treatment guided by urodynamics (37%) compared with those whose treatment was based on history and clinical findings alone (36%) (for example, RR for the number with incontinence after the first year 1.02, 95% CI 0.86 to 1.21). It was calculated that the number of women needed to treat was 100 women (95% CI 86 to 114 women) undergoing urodynamics to prevent one extra individual being incontinent at one year.One trial reported adverse effects and no significant difference was found (RR 1.10, 95% CI 0.81 to 1.50). AUTHORS' CONCLUSIONS While urodynamic tests did change clinical decision making, there was some evidence that this did not result in better outcomes in terms of a difference in urinary incontinence rates after treatment. There was no evidence about their use in men, children, or people with neurological diseases. Larger definitive trials are needed in which people are randomly allocated to management according to urodynamic findings or to management based on history and clinical examination to determine if performance of urodynamics results in higher continence rates after treatment.

Abstract
INTRODUCTION/HYPOTHESIS Stress incontinence with vaginal prolapse reduction is less common in women with posterior-predominant prolapse (rectocele) compared with those with anterior-predominant prolapse (cystocele). METHODS This was a secondary analysis of a cohort of prospectively enrolled women with symptomatic pelvic organ prolapse at or beyond the hymen and prolapse-reduced stress urinary incontinence (SUI) testing. Subjects were included if they had anterior- or posterior-predominant prolapse with at least a 1 cm difference in pelvic organ prolapse quantification (POP-Q) points Ba and Bp (N = 214). We evaluated the prevalence and risk factors of post-reduction SUI between the two groups. RESULTS Comparing posterior (n = 45) and anterior (n = 169) prolapse groups, we identified similar rates of post-reduction SUI (posterior: 6/45, 13.3 %; anterior:18/169, 10.7 %; p = 0.52) and SUI without reduction (posterior:4.4 %; anterior:11.2 %; p = 0.26). Maximum prolapse size was slightly larger in anterior than in posterior patients (+3.1 vs +2.0 cm beyond the hymen, p = 0.001), while a higher proportion of posterior subjects reported a prior hysterectomy (p = 0.04). Among posterior subjects, lower maximum urethral closure pressure values (MUCP; p = 0.02) were associated with post-reduction SUI. In contrast, among anterior-predominant prolapse, larger prolapse measured at POP-Q point Ba (p = 0.003) and maximum POP-Q measurement (p = 0.006) were each associated with higher rates of post-reduction SUI and were highly correlated with each other (R = 0.90). CONCLUSIONS We observed similar rates of post-reduction SUI in women with anterior- and posterior-predominant pelvic organ prolapse. Factors affecting the anterior and posterior prolapse groups differed, suggesting different mechanisms of continence protection. These findings suggest that reduction incontinence testing for operative planning would be as relevant to posterior-predominant prolapses as it is to anterior prolapse.

Abstract
PURPOSE The authors of this guideline reviewed the literature regarding use of urodynamic testing in common lower urinary tract symptoms. The findings are intended to assist clinicians in the appropriate selection of urodynamic tests, following an evaluation and symptom characterization. MATERIALS AND METHODS A systematic review of the literature using the MEDLINE® and EMBASE databases (searched from 1/1/90 to 3/10/11) was conducted to identify peer-reviewed publications relevant to using urodynamic tests for diagnosis, determining prognosis, guiding clinical management decisions and improving patient outcomes in patients with various urologic conditions. The review yielded an evidence base of 393 studies after application of inclusion/exclusion criteria. These publications were used to create the evidence basis for characterizing the statements presented in the guideline as Standards, Recommendations or Options. When sufficient evidence existed, the body of evidence for a particular treatment was assigned a strength rating of A (high), B (moderate) or C (low). In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinion. RESULTS The evidence-based guideline statements are provided for diagnosis and overall management of common LUTS conditions. CONCLUSIONS The Panel recognizes that each patient presenting with LUTS is unique. This Guideline is intended to serve as a tool facilitating the most effective utilization of urodynamic testing as part of a comprehensive evaluation of patients presenting with LUTS.

Abstract
Despite technical and procedural advances in urodynamics over the past decade, the role of urodynamics in women with stress urinary incontinence (SUI) remains controversial. Many of these advancements have been the result of multicentric studies in the United States, such as the UITN and PFDN, which will be highlighted in this article. It appears to be the consensus that urodynamics may not be needed in pure stress incontinence. Urodynamics can be valuable in unmasking stress urinary incontinence in prolapse, although its impact on the ultimate management of occult incontinence remains debated. This article reviews the indications for urodynamic testing in women with SUI but will exclude more complex conditions such as mixed or recurrent incontinence which are outside the scope of this review.

Abstract
INTRODUCTION AND HYPOTHESIS The unexpected absence of urodynamic stress incontinence (USI) in women planning surgery for stress urinary incontinence (SUI) is a challenge to surgeons. We examined the prevalence and clinical and demographic factors associated at baseline (preoperatively) with the unexpected absence of USI among study participants of two multicenter randomized clinical trials of surgery for treating SUI. METHODS Women with SUI symptoms and positive stress tests on physical examination enrolled in two separate clinical trials-one comparing the autologous fascial sling with the Burch colposuspension [Stress Incontinence Surgical Treatment Efficacy Trial (SISTEr), and the other comparing the retropubic mid-urethral sling with the transobturator midurethral sling [Trial of Mid-Urethral Slings (TOMUS)]-were evaluated for USI preoperatively. The association of clinical, demographic, and urodynamic parameters was examined in women without USI in univariate and multivariate analyses. RESULTS Overall, 144 of 1,233 women (11.7 %) enrolled in the two studies showed no USI. These women had a significantly lower mean volume at maximum cystometric capacity than those with USI (347.5 vs. 395.8 in SISTEr, p = 0.012), (315.2 vs. 358.2 in TOMUS, p = 0.003) and a lower mean number of daily accidents reported on a 3-day diary (2.2 vs 2.7 in SISTEr, p = 0.030) (1.7 vs 2.7 in TOMUS, p < 0.001). Additionally, those without demonstrable USI were more likely to have Pelvic Organ Prolapse Quantification (POP-Q) stage III/IV (31.7 % vs 14.4 % in SISTEr, p = 0.002), (15.5 % vs 6.9 % in TOMUS, p = 0.025). SUI severity as recorded on the Urogenital Distress Inventory (UDI) correlated strongly with the presence of USI in both studies. CONCLUSIONS We observed that about one of eight women planning surgery for SUI does not show USI. Stage 3/4 POP was strongly associated with the unexpected absence of USI. A diminished urodynamic bladder capacity among women who did not display USI may reflect an inability to reach the limits of capacity during urodynamics, at which these women normally leak.

Abstract
PURPOSE We compared the proportion of women with complex repetitive discharges on urethral sphincter electromyography during filling cystometry among women with and without urinary disorders. MATERIALS AND METHODS After receiving institutional review board approval we recruited community dwelling women without urinary symptoms and women who presented for urinary incontinence treatment. Participants completed the Pelvic Floor Distress Inventory. Women who responded affirmatively to an inventory item ("Do you have difficulty emptying your bladder?" or "Do you experience a feeling of incomplete bladder emptying?") were classified with voiding dysfunction. Women with post-void residual urine greater than 100 ml, active urinary tract infection, prolapse greater than stage II or neuromuscular disease were excluded from study. Participants underwent standardized multichannel urodynamics with continuous concentric needle electromyography of the urethral sphincter throughout filling cystometry. RESULTS In the 31 controls and 56 incontinent participants mean±SD age was 48±15 years and median vaginal parity was 1 (range 0 to 2). The urodynamic diagnosis in the incontinent group included urodynamic stress incontinence in 31 (56%), detrusor overactivity with incontinence in 17 (30%) and mixed urodynamic stress incontinence with detrusor overactivity in 8 (14%). Of the women 26 (32%) met voiding dysfunction criteria with 96% reporting a feeling of incomplete bladder emptying and 53% reporting difficult bladder emptying. Controls were significantly more likely to have complex repetitive discharges than incontinent women (9 of 30 vs 2 of 56, p<0.002). CONCLUSIONS Complex repetitive discharges occur in about a third of women without urinary symptoms.

Abstract
BACKGROUND Urodynamic tests are used to investigate people who have urinary incontinence or other urinary symptoms in order to make a definitive objective diagnosis. The aim is to help to select the treatment most likely to be successful. The investigations are invasive and time consuming. OBJECTIVES The objective of this review was to discover if treatment according to a urodynamic-based diagnosis, compared to treatment based on history and examination, led to more effective clinical care of urinary incontinence and better clinical outcomes. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Trials Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and CINAHL, and handsearching of journals and conference proceedings (searched 24 May 2011), and the reference lists of relevant articles. SELECTION CRITERIA Randomised and quasi-randomised trials comparing clinical outcomes in groups of people who were and were not investigated using urodynamics, or comparing one type of urodynamics against another. Trials were excluded if they did not report clinical outcomes. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality and extracted data. MAIN RESULTS Seven small trials involving around 400 people were included but data were only available for 385 women in five trials, of whom 197 received urodynamics. There was some evidence of risk of bias. The four deaths and 12 dropouts in the control arm of one trial were unexplained.There was some evidence that the tests did change clinical decision making. There was evidence from two trials that women treated after urodynamic investigations were more likely to receive drugs (RR 2.09, 95% CI 1.32 to 3.31) but not, in three trials, surgery (RR 1.75, 95% CI 0.39 to 7.75). Women in the urodynamic arms of two trials were more likely to have their management changed but this did not quite reach statistical significance (proportion with no change in management 76% versus 99%, RR 0.79, 95% CI 0.57 to 1.10).However, there was not enough evidence to demonstrate whether or not this resulted in a clinical benefit. For example there was no statistically significant difference in the number of women with urinary incontinence if they received treatment guided by urodynamics (70%) versus those whose treatment was based on history and clinical findings alone (62%) (e.g. RR for number with incontinence after first year 1.23, 95% CI 0.60 to 2.55).No trials reported whether or not there were any adverse effects. AUTHORS' CONCLUSIONS While urodynamic tests may change clinical decision making, there was not enough evidence to suggest whether this would result in better clinical outcomes. There was no evidence abut their use in men, children or people with neurological diseases. Larger definitive trials are needed, in which people are randomly allocated to management according to urodynamic findings or to standard management based on history and clinical examination.

Abstract
INTRODUCTION AND HYPOTHESIS We examined how preoperative urodynamic findings are related to the urinary problems following surgical repair of pelvic organ prolapse (POP). METHODS The clinical records of 87 women who underwent surgery for POP were reviewed retrospectively. Preoperatively, cough stress test and urodynamic testing, including pressure-flow study, were performed with prolapse reduction. Postoperative evaluation included uroflowmetry, postvoid residuals, and symptom assessment using questionnaires. RESULTS A cough stress test with simple filling was sufficient for diagnosis of occult stress urinary incontinence (SUI). The presence of detrusor overactivity was a good predictor of postoperative persistence of urgency and urge urinary incontinence. Postvoid residuals (PVR) largely increased immediately after surgery, but usually recovered within 1 month. Poor detrusor contractility was the best predictor of large PVR occurrence. CONCLUSIONS Preoperative urodynamic evaluation of SUI and detrusor function was useful for predicting postoperative urinary conditions in POP patients. Its cost-effectiveness remains to be examined.

Abstract
OBJECTIVE Symptoms of urinary incontinence often do not correlate well with the diagnosis provided by urodynamic investigations. Video urodynamics has been described as the "gold standard" investigation for patients with lower urinary tract symptoms. The aim of our study was to determine the concordance of diagnoses made on multi-channel and video urodynamics in women presenting with urinary incontinence to a tertiary care urogynaecology unit. MATERIALS AND METHODS We performed a retrospective chart review of 38 women who had video urodynamics and a multi-channel study completed within a one-year period. All patients had a complete history and pelvic floor assessment. The investigators completing each study were blinded to the clinical diagnoses, the physical findings, and the other urodynamics diagnoses. International Continence Society standards were followed for completion of all urodynamics investigations. Multi-channel studies were completed with the patient lying supine and video studies were performed with the patient sitting on a commode. The level of agreement of the diagnoses was calculated using a kappa (kappa) statistic with 95% confidence intervals (CI). RESULTS The median age of subjects was 61 years (range 14-79), with a median duration of lower urinary tract symptoms of 6.0 years (range 0.5-41). Patients had had a median of two previous bladder surgeries (range 0-5). The level of concordance of the two diagnoses gave a kappa of 0.16 (95% CI 0.06-0.26). CONCLUSIONS There was poor concordance between the diagnoses made on multi-channel and video urodynamics when the two tests were performed on the same patient. Prospective studies are required to evaluate the reproducibility of diagnoses made on cystometry.

Abstract
AIMS To (1) correlate peak and maximum flow rates from non-instrumented flow (NIF) and pressure-flow studies (PFS) in women with pelvic organ prolapse (POP); (2) measure the impact of voided volume and degree of prolapse on correlations. METHODS We compared four groups of women with stages II-IV POP. Groups 1 and 2 were symptomatically stress continent women participating in the colpopexy and urinary reduction efforts (CARE) trial; during prolapse reduction before sacrocolpopexy, Group 1 (n = 67) did not have and Group 2 (n = 84) had urodynamic stress incontinence (USI). Group 3 (n = 74) and Group 4 participants (n = 73), recruited specifically for this study, had stress urinary incontinence (SUI) symptoms. Group 3 planned sacrocolpopexy. Group 4 planned a different treatment option. Participants completed standardized uroflowmetry and pressure voiding studies. RESULTS Subjects' median age was 61 years; median parity 3% and 80% had stage III or IV POP. Based on the Blaivas-Groutz nomogram, 49% of all women were obstructed. NIF and PFS peak and average flow rates had low correlations with one another (0.31, P < 0.001 and 0.35, P < 0.001, respectively). When NIF and PFS voided volumes were within 25% of each other, the peak and average flow rate correlations improved (0.52, P < 0.001 and 0.57, P < 0.001, respectively). As vaginal prolapse increased, correlations between NIF and PFS peak and average flow rates decreased. CONCLUSION Peak and average flow rates are highly dependent on voided volume in women with prolapse. As the prolapse stage increases, correlations between NIF and PFS variables decrease.

Abstract
Female pelvic floor dysfunction (FPFD) is a complex group of conditions that include urinary incontinence and pelvic organ prolapse (POP). In humans, elastin homeostasis has been implicated in the pathophysiology of FPFD. Lysyl oxidase-like 1 knockout (LOXL1-KO) mice demonstrate abnormal elastic fiber homeostasis and develop FPFD after parturition. We compared the lower urogenital tract (LUT) anatomy and function in LOXL1-KO mice with and without POP. LUT anatomy was assessed in LOXL1-KO mice over 28 wk. Pelvic visceral anatomy in LOXL1-KO was evaluated with a 7-Tesla magnetic resonance imaging (MRI) scanner. LUT function was assessed using conscious cystometry and leak point pressure (LPP) testing. Quantitative histological analysis of elastic fibers was performed on external urethral sphincter (EUS) cross sections. By 25 wk of age, 50% of parous LOXL1-KO mice developed POP. LOXL1-KO mice with POP had greater variability in the size and location of the bladder on MRI compared with mice without POP. Parity and POP were associated with lower LPP. Elastin clusters were significantly increased in the EUS of LOXL1-KO mice with POP. Because parity triggers POP in LOXL1-KO mice, LOXL1-KO mice with POP have variable internal pelvic anatomy, and both parity and POP are associated with a decrease in LPP, we conclude that LOXL1 LUT anatomical and functional phenotype resembles FPFD in humans. The increase in elastin clusters in the urethra of LOXL1-KO mice with POP suggests that elastin disorganization may lead to functional abnormalities. We conclude that LOXL1 warrants further investigation in the pathphysiology of FPFD.
