Impact of Concomitant Coronary Artery Bypass Grafting on Postoperative Outcomes in Patients Undergoing Pericardiectomy: A 33 Year Experience. JTCVS OPEN 2022; 13:178-183. [PMID: 37063133 PMCID: PMC10091208 DOI: 10.1016/j.xjon.2022.10.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 10/15/2022] [Accepted: 10/26/2022] [Indexed: 11/17/2022]
Abstract
Objective Concomitant coronary artery bypass grafting (CABG) and pericardiectomy (PC) can be a technically challenging operation. We sought to study the outcomes of patients undergoing concomitant PC and CABG. Methods Between July 1983 and August 2016, 70 patients (median age, 67 years; 88% males) underwent concomitant PC and CABG (PC + CABG group). Multivariable analysis was used to identify predictors of mortality. Matched patients who underwent isolated PC (PC group) were identified, and postoperative outcomes and long-term survival in the 2 groups were compared. Results Compared with the PC group, cardiopulmonary bypass time was significantly longer in the PC + CABG group (82 minutes vs 61 minutes; P < .001). In-hospital mortality was 4% in the PC group and 7% in the PC + CABG group (P = .380). Multivariable analysis identified peripheral vascular disease (hazard ratio [HR], 2.67; 95% CI, 1.06-6.76; P = .04) as a predictor of increased morbidity or mortality and a borderline association with New York Heart Association functional classes III and IV (HR, 2.41; 95% CI, 0.99-5.86; P = .05) with increased morbidity and mortality in the PC + CABG group. Kaplan-Meier estimates demonstrated similar late mortality rates in the 2 groups at a 15-year follow-up (P = .700). Conclusions Concomitant PC and CABG is not associated with increased morbidity or mortality compared with isolated PC. Thus, CABG should not be denied at the time of PC.

Coronary Artery Bypass Grafting in Octogenarians-Risks, Outcomes, and Trends in 1283 Consecutive Patients. Mayo Clin Proc 2022; 97:1257-1268. [PMID: 35738944 DOI: 10.1016/j.mayocp.2022.03.033] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 03/03/2022] [Accepted: 03/31/2022] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To describe the risks, outcomes, and trends in patients older than 80 years undergoing coronary artery bypass grafting (CABG). METHODS We retrospectively studied 1283 consecutive patients who were older than 80 years and underwent primary isolated CABG from January 1, 1993, to October 31, 2019, in our clinic. Kaplan-Meier survival probability and quartile estimates were used to analyze patients' survival. Logistic regression models were used for analyzing temporal trends in CABG cases and outcomes. A multivariable Cox proportional hazards regression model was developed to study risk factors for mortality. RESULTS Operative mortality was overall 4% (n=51) but showed a significant decrease during the study period (P=.015). Median follow-up was 16.7 (interquartile range, 10.3-21.1) years, and Kaplan-Meier estimated survival rates at 1 year, 5 years, 10 years, and 15 years were 90.2%, 67.9%, 31.1%, and 8.2%, respectively. Median survival time was 7.6 years compared with 6.0 years for age- and sex-matched octogenarians in the general US population (P<.001). Multivariable Cox regression analysis identified older age (P<.001), recent atrial fibrillation or flutter (P<.001), diabetes mellitus (P<.001), smoking history (P=.006), cerebrovascular disease (P=.04), immunosuppressive status (P=.01), extreme levels of creatinine (P<.001), chronic lung disease (P=.02), peripheral vascular disease (P=.02), decreased ejection fraction (P=.03) and increased Society of Thoracic Surgeons predicted risk score (P=.01) as significant risk factors of mortality. CONCLUSION Although CABG in octogenarians carries a higher surgical risk, it may be associated with favorable outcomes and increase in long-term survival. Further studies are warranted to define subgroups benefiting more from surgical revascularization.

Abstract
We present a patient with post-infarction posterior ventricular septal defect complicated by cardiogenic shock who was transferred after percutaneous coronary revascularization. A peripheral venoarterial extracorporeal membrane oxygenator was placed as a bridge to definite treatment to stabilize his condition. Patch closure of the ventricular septal defect and tricuspid valve replacement were performed successfully with right atrial approach 3 days after the extracorporeal membrane oxygenation (ECMO) placement and 11 days after the myocardial infarction. The extracorporeal membrane oxygenator was successfully weaned off intraoperatively and the patient was discharged without complications.

Comparative Effectiveness of Mechanical Valves and Homografts in Complex Aortic Endocarditis. Ann Thorac Surg 2020; 111:793-799. [PMID: 32890491 DOI: 10.1016/j.athoracsur.2020.06.082] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Revised: 05/07/2020] [Accepted: 06/17/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND The ideal surgical reconstruction of the aortic root in patients with complex endocarditis is controversial. We compared the short- and long-term outcomes between mechanical valves, bioprostheses, and homografts. METHODS We identified all patients undergoing an operation for active complex aortic endocarditis at our institution between 2003 and 2017. We grouped patients according to those who received a mechanical valve, bioprosthesis, or homograft. We used multiple logistic regression and proportional hazards models. To minimize confounding by indication, we used marginal risk adjustment to simulate that every patient would undergo (contrary to fact) all 3 operations. RESULTS Of 159 patients with complex active endocarditis, 48 (30.2%) had a valve plus patch reconstruction, and 85 (53.4%) had a root replacement. Of all, 50 (31.5%) had a mechanical valve, 56 (35.2%) had a bioprosthesis, and 53 (33.3%) had a homograft. The groups were similar in age, sex, body mass index, comorbid conditions, organism, abscess location, and mitral involvement (all P > .05). However, patients receiving mechanical reconstructions were more likely to have native valve endocarditis (46% vs 37.5% vs 17%; P = .005) and less likely to undergo root replacement (32% vs 28.6% vs 100%; P < .001). Marginal risk-adjusted operative mortality was lowest for mechanical valves (4.8%) and highest for homografts (16.9%; P = .041). Long-term survival after root replacement was worse with homografts than with mechanical valve conduits (adjusted hazard ratio, 2.9; P = .045). CONCLUSIONS In patients with complex endocarditis, mechanical valves are associated with similar, if not better, short- and long-term outcomes compared with homografts, even after adjusting for important baseline characteristics and limiting the analysis to root replacements only.

Abstract
We report a 62-year-old male who had severe aortic insufficiency after a homograft root replacement, requiring venoarterial extracorporeal membrane oxygenation prior to surgery due to profound cardiogenic shock. Severe aortic insufficiency is a contraindication for venoarterial extracorporeal membrane oxygenation, but we were able to stabilize the patient and successfully perform an urgent reoperative surgery.

Abstract
The conventional management of irritative bladder symptoms, namely urgency, urge incontinence, frequency and nocturia, with anticholinergic medication is limited by the side effects of treatment. Acupuncture is shown to be as effective in the management of irritative bladder symptoms as conventional anticholinergic therapy, with few side effects and a high degree of patient acceptability and compliance.

Abstract
Supravalvular aortic stenosis is a less common form of left ventricular outflow tract obstruction (LVOTO); commonest being the valvular aortic stenosis followed by valvular and subvalvular forms respectively. Most of the supravalvular aortic stenosis is associated with Williams syndrome; isolated supravalvular aortic stenosis is further rarer. We present a case of isolated SVAS with infective endocarditis (1.6) as the cause of pyrexia of unknown origin (PUO).

Abstract
CONTEXT Mirabegron, the selective β3-adrenoceptor agonist, heralds the latest development for the treatment of overactive bladder (OAB). OBJECTIVE To present the evidence available on the efficacy and tolerability of mirabegron and to discuss this treatment's potential in our setting. EVIDENCE ACQUISITION We reviewed 11 studies conducted with mirabegron in patients with OAB (2 phase II, 9 phase III), all studies were compared to placebo with 6 studies also including tolterodine as an additional arm. Greater emphasis shall be given to the main phase III trials performed in Europe, the USA and Australia evaluating efficacy and safety after 12 weeks (NCT00662909, NCT00689104, NCT00912964) and safety after 12 months (NCT00688688). The combined analyses of these 12 week studies is also available, with emphasis on global efficacy (FAS), efficacy with regard to incontinence (FAS i) and safety (SAF). More than 50% of patients had previously discontinued anticholinergics medication for OAB, thus allowing us to obtain data on the effectiveness of mirabegron in patients already treated with anticholinergics. EVIDENCE SYNTHESIS Mirabegron is an efficacious drug which presents a statistically significant reduction in the number of incontinence episodes and in urinary frequency as of 4 weeks, with a higher percentage of dry patients and a higher percentage of patients with reduction ≥50% in the number of incontinence episodes than placebo. The efficacy of mirabegron 50 and 100mg in the reduction of incontinence episodes occurs in de novo patients and who have received antimuscarinics, with adjusted mean difference and improvement in urinary frequency greater in treated patients. Its tolerability is very similar to placebo particularly for the adverse effects of the antimuscarinics (dry mouth, constipation and blurred vision). A minimal, non-clinically significant change is observed in systolic and diastolic blood pressure and pulse. Its efficacy is long-term. Mirabegron at the doses of 50 and 100mg presents an improvement versus placebo in patient satisfaction, health-related quality of life (HRQoL), symptom bother and patient's perception of bladder condition (PPBC). In the 12 week Phase III European study tolterodine delivered a lesser degree of improvement than mirabegron versus placebo in patient satisfaction, HRQoL, symptom bother and PPBC. CONCLUSIONS Mirabegron is the first of a new class of compounds with a novel mechanism of action that is different to the antimuscarinics. It presents significant and clinically important efficacy in the treatment of the symptoms of OAB. It has advantages with regard to the results described by the patient in treatment satisfaction. Studies on its combined use with anticholinergics are ongoing.

Abstract
INTRODUCTION To examine pooled efficacy data from three, large phase III studies comparing mirabegron (50 and 100 mg) with placebo, and pooled safety data including additional mirabegron 25 mg and tolterodine extended release (ER) 4 mg results. METHODS This prespecified pooled analysis of three randomised, double-blind, placebo-controlled, 12-week studies, evaluated efficacy and safety of once-daily mirabegron 25 mg (safety analysis), 50 or 100 mg (efficacy and safety analyses) and tolterodine ER 4 mg (safety analysis) for the treatment of symptoms of overactive bladder (OAB). Co-primary efficacy measures were change from baseline to Final Visit in the mean number of incontinence episodes/24 h and mean number of micturitions/24 h. Key secondary efficacy end-points included mean number of urgency episodes/24 h and mean volume voided/micturitions, while other end-points included patient-reported outcomes according to the Treatment Satisfaction-Visual Analogue Scale (TS-VAS) and responder analyses [dry rate (posttreatment), ≥ 50% reduction in incontinence episodes/24 h, ≤ 8 micturitions/24 h (post hoc analysis)]. The safety analysis included adverse event (AE) reporting, laboratory assessments, ECG, postvoid residual volume and vital signs (blood pressure, pulse rate). RESULTS Mirabegron (50 and 100 mg once daily) demonstrated statistically significant improvements compared with placebo for the co-primary end-points, key secondary efficacy variables, TS-VAS and responder analyses (all comparisons p < 0.05). Mirabegron is well tolerated and demonstrates a good safety profile. The most common AEs (≥ 3%) included hypertension, nasopharyngitis and urinary tract infection (UTI); the incidence of hypertensive events and UTIs decreased with increasing dose. For mirabegron, the incidence of the bothersome antimuscarinic AE, dry mouth, was at placebo level and of a lesser magnitude than tolterodine. CONCLUSION The efficacy and safety of mirabegron are demonstrated in this large pooled clinical trial dataset in patients with OAB.

Abstract
BACKGROUND Patients' treatment goals for overactive bladder (OAB) and other lower urinary tract symptoms (LUTS) may not be aligned with their healthcare provider's goals. Successful management of OAB symptoms is improved by individualised treatment plans with attainable treatment goals. Goal attainment setting may facilitate patient-provider interaction and the development of a personalised treatment plan based on realistic, individual goals, thereby increasing patient satisfaction and therapeutic outcomes. The purpose of this study was to validate the utility of the Self-Assessment Goal Achievement (SAGA) questionnaire for LUTS in helping patients identify and achieve realistic treatment goals. METHODS The 2-module SAGA questionnaire consists of nine prespecified (fixed) items and five open-ended items for goal identification and ranking (baseline module) and goal achievement rating (follow-up module). Adult patients in the United States (n = 104) seeking treatment for LUTS, including symptoms of OAB, completed the SAGA baseline module, micturition diary, other patient-reported outcome measures (PROs), and discussed their urinary goals with a clinician at baseline. The SAGA follow-up module was completed 2-4 months later. SAGA was validated based on analyses of face, concurrent, known-groups, and convergent validity and item distribution. RESULTS Among the nine fixed goals of SAGA, four were ranked as very important by > 50% of patients (i.e. reduce night-time frequency, daytime frequency, urine leakage, urgency). Most patients did not change the importance level of their goals after discussion with their healthcare provider. Pearson correlations between SAGA, diary variables and PRO scores were generally of low to moderate strength. The global mean (SD) follow-up SAGA T-score was 32.54 (12.54), indicating that overall goal attainment was not achieved after 3 months. The goal attainment score was significantly different between groups differing in symptom severity, health-related quality of life, bladder control and continence status. CONCLUSIONS The results support the validity of SAGA as a measure of patients' goals and goal achievement for the treatment of LUTS, including symptoms of OAB. SAGA may improve healthcare provider-patient interactions and treatment outcomes in clinical practice.

Abstract
BACKGROUND The complex relationship between bladder and bowel function has implications for treating pelvic disorders. In this systematic review, we discuss the relationship between bladder and bowel function and its implications for managing coexisting constipation and overactive bladder (OAB) symptoms. METHODS Multiple PubMed searches of articles published in English from January 1990 through March 2011 were conducted using combinations of terms including bladder, bowel, crosstalk, lower urinary tract symptoms, OAB, incontinence, constipation, hypermotility, pathophysiology, prevalence, management and quality of life. Articles were selected for inclusion in the review based on their relevance to the topic. RESULTS Animal studies and clinical data support bladder-bowel cross-sensitization, or crosstalk. In the rat, convergent neurons in the bladder and bowel as well as some superficial and deeper lumbosacral spinal neurons receive afferent signals from both bladder and bowel. On a functional level, in animals and humans, bowel distention affects bladder activity and vice versa. Clinically, the bladder-bowel relationship is evident through the presence of urinary symptoms in patients with irritable bowel syndrome and bowel symptoms in patients with acute cystitis. Functional gastrointestinal disorders, such as constipation, can contribute to the development of lower urinary tract symptoms, including OAB symptoms, and treatment of OAB with antimuscarinics can worsen constipation, a common antimuscarinic adverse effect. The initial approach to treating coexisting constipation and OAB should be to relieve constipation, which may resolve urinary symptoms. CONCLUSIONS The relationship between bladder and bowel function should be considered when treating patients with urinary symptoms, bowel symptoms, or both.

Abstract
INTRODUCTION AND HYPOTHESIS Overactive bladder (OAB) has a multifactorial aetiology, and for some women symptoms may be associated with chronic urothelial inflammation secondary to bacterial colonisation. One marker of such inflammation may be urinary nerve growth factor (NGF). We hypothesised that for women with OAB and urothelial inflammation, urinary NGF would be reduced following antibiotic therapy. METHODS Women with overactive bladder and urodynamic diagnosis of detrusor overactivity who were refractory to anticholinergics, and had histological evidence of urothelial inflammation were treated with a 6-week course of rotating antibiotics. Urinary NGF was measured by ELISA before and after treatment. Three-day bladder diaries, the Patients' Perception of Intensity of Urgency Scale, the King's Health Questionnaire and the Patients' Perception of Bladder Condition questionnaire were used to assess subjective and objective outcomes of therapy. RESULTS Thirty-nine women with refractory DO were recruited. The NGF levels decreased significantly after antibiotic therapy (Wilcoxon signed rank test; p = 0.015). There were significant improvements in daytime frequency, nocturia and urgency (p < 0.05), and 74 % of women reported improvement in perception of their bladder condition. CONCLUSIONS Urinary NGF is responsive to antibiotic therapy. Women with refractory overactive bladder and elevated NGF may benefit from antibiotic treatment.

Abstract
Lower urinary tract symptoms (LUTS) have a detrimental effect on quality-of-life (QoL). However, sufferers are often reluctant to seek help. Screening for LUTS will identify patients with bothersome symptoms who may benefit from treatment and allow patients to self-assess their symptoms and the need for medical intervention, potentially saving costly medical time and reducing long-term morbidity. The aim of this study was to compare the value of two validated questionnaires: the Bladder Control Self Assessment Questionnaire (B-SAQ) and the Overactive Bladder Awareness Tool (OAB-V8) as screening questionnaires in clinical practice. A total of 223 women were recruited prospectively from three centres. Participants completed both questionnaires in the waiting area prior to assessment by a clinician, who completed a symptom evaluation sheet. Data were analysed using receiver operating characteristic curves. Both the B-SAQ and the OAB-V8 performed well in detecting symptoms of OAB and mixed urinary symptoms. The B-SAQ performed better in detecting symptoms of stress incontinence than the OAB-V8. The opportunity to screen for haematuria should never be missed and this is an important omission from the OAB-V8.

Abstract
Background: Percutaneous tibial nerve stimulation (PTNS) has been proposed as a new, minimally invasive neuromodulation technique to treat lower urinary tract symptoms (LUTS). Objective: To evaluate efficacy, safety and impact on quality of life (QoL) of PTNS on patients with multiple sclerosis (MS) who have LUTS. Methods: 21 patients (5 men, 16 women) with MS and LUTS unresponsive to anticholinergics were treated with 12 sessions of PTNS. Assessment of LUTS was by validated, self-administered chart and questionnaires, testing the subjective and objective relevance of LUTS for patients and their impact on QoL before and after treatment; the mean post-micturition residual was assessed by trans-abdominal ultrasound scanning. Analysis was by intention to treat. Results: There was a significant reduction of daytime frequency (from 9 to 6, p = 0.04), nocturia (from 3 to 1, p = 0.002) and mean post-micturition residual (from 98 ± 124 ml to 43 ± 45 ml, p = 0.02). The mean voided volume increased from 182 ± 50 ml to 225 ± 50 ml ( p = 0.003). Eighty-nine percent of patients reported a treatment satisfaction of 70%. Significant improvement in QoL was seen in most domains of the King’s Health QoL questionnaire ( p < 0.05). No adverse events were reported. Conclusions: PTNS is an effective, safe and well-tolerated treatment for LUTS in patients with MS.

Abstract
OBJECTIVES To create reference intervals of gestational sac volume (GSV), yolk sac volume (YSV), embryo volume (EV), crown-rump length (CRL) and gestational sac diameter (GSD) in the first trimester of pregnancy using three-dimensional ultrasound. METHODS Women in the first trimester of pregnancy were invited to participate in the study. Inclusion criteria were well-established dates, and that the women were non-smokers and healthy, without any medical disorders. Three-dimensional ultrasound volumetric data (GSV, YSV, EV) were collected together with standard two-dimensional measurements of CRL and GSD. For each measurement separate regression models were fitted to estimate the mean and SD at each gestational age. The 5(th), 50(th) and 95(th) centiles were derived using a combination of these regression models. RESULTS One hundred and sixty-six women at between 6 and 12 weeks' gestation were scanned once. The mean ( +/- SD) maternal age was 29.4 ( +/- 5) years. There were no miscarriages and no congenital abnormalities were noted. Mean gestational age at delivery was 39.3 ( +/- 1.4) weeks and mean birth weight was 3.3 ( +/- 0.4) kg. The CRL centiles fitted a cubic model and the GSD centiles fitted a linear model. The centiles for YSV fitted a quadratic model on the modified log-transformed data. The centiles for GSV and EV were modeled using quantile regression. CONCLUSION Reference intervals and centile charts for first-trimester GSV, YSV and EV have been created in addition to CRL and GSD using rigorous methodology.

Abstract
AIMS To determine if specific pre-operative urodynamic parameters could predict detrusor overactivity following TVT in patients with urodynamic mixed incontinence. METHODS Notes of women with detrusor overactivity (DO) and urodynamic stress incontinence (USI) before undergoing tension-free vaginal tape (TVT) surgery were retrospectively reviewed. Patients underwent clinical evaluation pre-operatively including history, examination, and conventional urodynamic studies and were treated with pelvic floor exercises and anti-cholinergic medication. Those with persistent stress urinary incontinence (SUI) underwent TVT. Patients were re-assessed after at least 6 months post-operatively. Pre- and post-operative opening and closing detrusor pressure, and detrusor pressure at maximum flow were recorded retrospectively from pre-operative urodynamics traces by two clinicians independently and compared to the patients' post-operative symptoms and urodynamic diagnosis. RESULTS Fifty-one women were reviewed. Forty-six of the 51 attended follow-up and 35/51 agreed to conventional urodynamic studies. Seventeen of the 35 reported OAB symptoms, and 18/35 were asymptomatic. Nineteen of the 35 women had DO and 16/35 had normal urodynamic studies (NUDS). The median pre-operative opening detrusor pressure was higher in women with overactive bladder symptoms post-operatively. The median pre-operative opening detrusor pressure in women with DO post-operatively was 33.0 cmH(2)O and the median pre-operative opening detrusor pressure in those with NUDS post-operatively was 16 cmH(2)O (15.0-23.0 cmH(2)O) (P < 0.05 Mann-Whitney U-test). CONCLUSIONS Higher numbers of patients are required to demonstrate the value of opening detrusor pressure in predicting post-operative overactive bladder symptoms. Opening detrusor pressure is predictive of post-operative DO after TVT.

Abstract
OBJECTIVE Anal-sphincter injury may result in faecal incontinence. Sphincteroplasty is usually performed as a primary (immediate) procedure. Delayed sphincteroplasty (DS) can be performed if there is significant trauma or soiling, if the primary procedure has failed, and if the injury was not recognized initially. This study aimed to determine the cost to patient and health service in the event a DS is performed. METHOD Patients with anal-sphincter-injury who underwent primary sphincteroplasty (PS)/DS were identified from the published literature (primary, n = 103; delayed, n = 777) using Medline, Embase, Ovid and Cochrane databases for studies published between 1976 and 2006. Studies included described at least one of the measured outcomes--probability of functional success/failure and quality of life (QOL). An economic model was constructed and decision analysis performed using a decision tree based on a Markov process. Main outcomes were quality-adjusted-life-years (QALYs) gained from each strategy, costs incurred and incremental cost-effectiveness ratio (ICER) over a 10- and 15-year time horizon. RESULTS Over 10 years, primary sphincteroplasty (PS) produced a gain of 5.72 QALYs for an estimated 2750 pounds, giving an ICER of 487 pounds per QALY. DS produced a gain of 3.73 QALYs for a cost of 2667 pounds, giving an ICER of 719 pounds per QALY. Both procedures fell below the 10,000 pounds per QALY willingness-to-pay threshold, but PS produced the highest QALYs. Both procedures performed poorly beyond the 10-year mark. CONCLUSION If DS has to be performed, the resultant cost is greater with concurrently lower QALYs gained. Successful PS substantially improves QOL and reduces overall cost-of-treatment.

Abstract
OBJECTIVE To evaluate the anatomy of the levator ani muscle in women with urogenital prolapse versus matched controls without prolapse using real-time two-dimensional (2-D) ultrasound. DESIGN Prospective observational study. SETTING Tertiary referral urogynaecology unit. POPULATION Forty-three women with pelvic organ prolapse (POP) and 24 women (controls) attending a gynaecology clinic without prolapse. METHODS All participants completed a standardised symptom questionnaire. MAIN OUTCOME MEASURES The morphology of the vagina and paravaginal tissue was recorded at different levels. The thickness of the levator ani and the hiatal area were measured at rest. Reproducibility of the method was assessed by repeated measurements to assess intra-observer variability and inter-observer variability. RESULTS This method showed good intra-observer and inter-observer reproducibility and reliability. In controls, the pubococcygeus muscle showed more regular echogenicity with no evidence of trauma, whereas in women with prolapse the muscle had mixed echogenicity. (P = 0.002). The mean thickness of the pubococcygeus did not differ between groups. The levator hiatal area was significantly larger in women with pelvic floor prolapse versus controls (17.8 cm2 versus 13.5 cm2, P < 0.001). This increase in hiatal area positively and significantly correlated with prolapse severity (P < 0.001). CONCLUSIONS Morphology and hiatal area can be reliably imaged using 2-D ultrasound. Prolapse was related to changes in pelvic floor morphology and increased levator hiatal area. The use of 2-D ultrasound provides an important insight into the pathophysiology of prolapse.

Abstract
OBJECTIVE The purpose of this study was to use magnetic resonance imaging to observe the changes of the position of the levator ani muscle relative to the bladder neck after Burch colposuspension. STUDY DESIGN Women with urodynamic stress incontinence underwent Burch colposuspension. Magnetic resonance imaging was performed 1 week before surgery and 1 year after the operation. The levator ani muscle and the bladder neck were imaged in the parasagittal and sagittal planes, respectively; and their position was measured in relation to the pubococcygeal line. The reproducibility of these measures was investigated. Changes that occurred to levator ani muscle anatomy after the operation were correlated to surgical success. Surgical outcome was assessed objectively at 1 year with urodynamic testing. RESULTS Of the 73 women who were studied, only 28 women were included in the study because the medial edge of the levator ani was visible clearly on a parasagittal magnetic resonance image. At the 1-year follow-up, the objective cure rate was 86%. Measures of bladder neck and levator ani position in relation to the pubococcygeal line were found to be reproducible. Burch colposuspension produces a significant elevation of the levator ani, with a reduced distance between the bladder neck and the levator ani muscle. Surgical success was associated significantly with a shorter distance between bladder neck and levator ani muscle. CONCLUSION The anatomy of the levator ani muscle is changed by colposuspension. The apposition of the levator ani muscle to the bladder neck may play a role in the restoration of continence.

Abstract
BACKGROUND We aimed to determine whether outpatient treatment of miscarriage with vaginal misoprostol is more effective than expectant management in reducing the need for surgical evacuation of retained products of conception (ERPC). METHODS Of 131 eligible women with first trimester miscarriage, 104 agreed to randomization to either 600 microg misoprostol or placebo intravaginally. They were assessed the following day and administered a second dose of their allocated treatment if miscarriage was not complete. Those not successful after two doses were seen on day 7, and, if miscarriage was not complete, an ERPC was performed. RESULTS The success rate of medical management was 88.5% (46/52) compared with 44.2% (23/52) for expectant management. There was no significant difference in success rate (100 versus 85.7%) in women treated with an incomplete miscarriage. Women with early pregnancy failure had a success rate of 87% with misoprostol compared with 29% with expectant management [odds ratio (OR) 15.96; 95% confidence interval (CI) 5.26, 48.37]. The complete miscarriage rate was achieved quicker in the medical group than the expectant group by day 1 (32.7 versus 5.8%) and by day 2 (73.1 versus 13.5%) of treatment. There were no differences in side-effects, bleeding duration, analgesia use, pain score and satisfaction with treatment. Women in the expectant group made more outpatient visits (5.06 versus 4.44%; OR = -0.62, 95% CI -1.04, -0.19). More women in the medical group (90.4 versus 73.1%; OR 1.26, 95% CI 1.05, 1.50) would elect the same treatment in the future. CONCLUSIONS Medical management using 600 microg misoprostol vaginally is more effective than expectant management of early pregnancy failure. Misoprostol did not increase the side-effect profile and patient acceptability was superior to expectant management.

Abstract
Urinary incontinence and lower urinary tract dysfunction remain an important cause of morbidity, affecting at least 14% of women over the age of 30 years. Whilst the etiology and pathophysiology of detrusor instability remains to be elucidated drug therapy remains important in the management of women with the irritative symptoms of urgency, frequency and urge incontinence. The number of drugs which have been developed illustrates the point that none are ideal, often having systemic adverse effects limiting their therapeutic usage and affecting compliance. This review aims to assess the current pharmacological management of detrusor instability as well as examining recent progress in the development of new agents, some of which may prove to be efficacious.

Abstract
OBJECTIVES To measure urethral sphincter volume by three-dimensional (3D) ultrasound. To assess the reproducibility of this measurement technique and to compare volumes obtained using 3D ultrasound with volumes calculated from a formula based on 2D ultrasound measurements. METHODS Women were recruited as part of an ongoing study of changes to the pelvis resulting from pregnancy and childbirth. One hundred and eleven women in the third trimester of pregnancy (between 32 and 41 completed weeks' gestation) underwent a 3D transvaginal ultrasound scan of the urethra. In 10 cases the scan was analyzed twice by different observers to assess the reproducibility of the measurements from the scans and the results were analyzed using limits of agreement. RESULTS The interobserver error was consistent between all the linear, 2D and 3D measurements obtained from the area scanned. There was a significant difference between volumes calculated directly by 3D ultrasound and the approximated volumes from conventional 2D measurements. CONCLUSIONS Three-dimensional ultrasound appears to be a useful tool in measuring urethral sphincter volume. The error is consistent with that of linear and 2D imaging. However, the increase in normal range generated by biological variation in all three planes makes 3D ultrasound a more sensitive method of evaluating change to the urethral sphincter.

Abstract
OBJECTIVES To investigate the impact of colposuspension for stress incontinence on the symptoms and quality of life of women undergoing both primary and repeat surgery for genuine stress incontinence and in addition to assess the use of a condition specific quality of life questionnaire as an outcome measure following surgery. DESIGN Prospective case series: videocystourethrography performed before and between six and twelve months after surgery. Validated condition specific quality of life (QoL) questionnaires completed by women before and six to twelve months after surgery. SETTING A tertiary referral Urogynaecology Unit in a teaching hospital. PARTICIPANTS A consecutive series of 83 women undergoing colposuspension between March 1995 and December 1997. Pre-operative assessment and surgery was performed by, or was under the direct supervision of, the unit director. INTERVENTION Modified Burch colposuspension. MAIN OUTCOME MEASURES Objective results of surgery assessed with videocystourethrography. Subjective results evaluated using a condition specific QoL tool, the Kings Health Questionnaire (KHQ). Symptom severity was evaluated as a component of the condition specific QoL questionnaire. RESULTS Objective cure was demonstrated in 92% of women undergoing primary surgery with an 8% incidence of de-novo detrusor instability and a 10% incidence of voiding difficulties. In the group of women having repeat surgery the objective cure rate was 81% with no de-novo detrusor instability and a 6% incidence of post-operative voiding difficulties. QoL scores improved in 95% of women. Improvements of over 25% were seen in 70% of women and of over 50% in 28%. However, 2.4% of women recorded a deterioration in QoL scores. CONCLUSIONS Colposuspension performed in this setting, assessed using both objective and standardised subjective measures, completed by women themselves, appears to produce good objective and subjective results and leads to enhanced quality of life in the great majority of women.

Abstract
OBJECTIVE To identify abnormal detrusor contractions in asymptomatic women undergoing ambulatory urodynamics, to standardise the investigation technique for women with urinary symptoms for clinical practice. DESIGN Prospective observational study. SETTING Two tertiary referral urogynaecology units: one in London, UK and one in Varese, Italy. METHODS Women without urinary symptoms were recruited into the study. Ambulatory urodynamics was performed according to the King's College Hospital protocol. All the traces were analysed in four different ways: 1. without the second bladder transducer measurements displayed on the screen and without the diary; 2. as in 1. but with the diary; 3. with the second bladder sensor displayed on the screen but without the diary; 4. as in 3. but with the diary. The diary was always interpreted at the end of the test with the woman present. For each method we reported the total number of detrusor contractions and whether the woman would have been diagnosed as having abnormal detrusor contraction. Cochran's Q test was used for statistical analysis. RESULTS Twenty-six women (mean age 31.7 years) were recruited. Ambulatory urodynamic testing lasted an average of 3.57 hour. The diagnosis of abnormal detrusor contraction varied by 65.4% depending on the method of analysis used. The diary and the women's symptoms during the test were the most discriminating factors. A significant difference between the diagnoses was obtained when comparing the four different ways of analysis. According to our protocol only three women (11.5%) had abnormal detrusor contractions. CONCLUSIONS Using our protocol almost 90% of asymptomatic women have a stable bladder on ambulatory urodynamics. This is similar to the results of labouratory urodynamic testing of asymptomatic women but is in contrast to previous reports of ambulatory urodynamics of asymptomatic women. The technique used during ambulatory urodynamics determines the tests ability to detect detrusor instability with an accurate symptom diary being the most important.

Abstract
Urethral function can be assessed using many different techniques and this is very important when applied to women with neurological abnormalities. Urethral pressure profilometry, although not diagnostic for urethral sphincter incompetence, can be used to detect strictures and the ostia leading to urethral diverticula. Urethral instability may be recorded using urethral pressure catheters. The significance of this finding is uncertain but it has been suggested that women with urethral instability and detrusor instability are less responsive to therapy with anticholinergic drugs than those with a stable urethra. Micturition pressure profilometry is useful for determining obstruction during voiding and enables the site of obstruction to be determined. Leak point pressures (LPP) can be classified as detrusor or abdominal. Detrusor LPP are useful in patients with neurological disease. Abdominal LPP are subdivided according to the method used to increase intra-abdominal pressure either the Valsalva manoeuvre or coughing. The technique used to obtain an LPP can alter the measurement obtained and a standardized technique is essential for consistent results. LPP correlate with the urinary incontinence of women with genuine stress incontinence undergoing a pad test but is of no value if the woman does not leak! Tests of urethral function during bladder filling, stress and voiding phases help in assessing lower urinary tract dysfunction in neurourology.

Abstract
OBJECTIVE To image the striated urethral sphincter (rhabdosphincter) using three-dimensional ultrasound and to compare its size in women with genuine stress incontinence and continent controls. METHODS Women with no previous continence or prolapse surgery had transvaginal sonography using a 7.5-MHz mechanical sector endoprobe with real-time and three-dimensional facilities. Three perpendicular planes were displayed simultaneously on the screen. Manipulation of the stored images allowed detailed morphologic assessment of the urethra at different levels using several parallel cross-sectional planes along its length. The length, thickness, and volume of the rhabdosphincter were measured. RESULTS Forty-six women with genuine stress incontinence (27-73 years, mean 48) and 48 continent controls (23-76 years, mean 49) were studied. In the transverse plane, the inner part of the urethra, which consists of urothelium and smooth muscle, appeared hyperechogenic compared with the outer hypoechogenic ring of striated muscle. The two groups studied were not different in age and parity. Women with genuine stress incontinence, compared with continent controls, had a significantly shorter (mean +/- standard deviation 16.9 +/- 1.9 mm compared with 19.2 +/- 3.6 mm; P = .001), thinner (2.1 +/- 0.5 mm compared with 2.5 +/- 0.4 mm; P < .001), and smaller volume (0.8 +/- 0.2 mL compared with 1.2 +/- 0.2 mm; P < .001) of the striated urethral sphincter. There was a close correlation between the urethral sphincter volume and the degree of incontinence assessed on videocystourethrography (r = -.65, P < .001). CONCLUSION Three-dimensional ultrasound allowed examination of the female urethra in planes that could not be visualized by conventional sonography. The rhabdosphincter had a smaller volume in women with genuine stress incontinence than in continent women.
