Translabial ultrasound assessment of the anal sphincter complex: normal measurements of the internal and external anal sphincters at the proximal, mid-, and distal levels.

The purpose of this study was to measure the internal and external anal sphincters using translabial ultrasound (TLU) at the proximal, mid, and distal levels of the anal sphincter complex. The human review committee approval was obtained and all women gave written informed consent. Sixty women presenting for gynecologic ultrasound for symptoms other than pelvic organ prolapse or urinary or anal incontinence underwent TLU. Thirty-six (60%) were asymptomatic and intact, 13 symptomatic and intact, and 11 disrupted. Anterior-posterior diameters of the internal anal sphincter at all levels and the external anal sphincter at the distal level were measured in four quadrants. Mean sphincter measurements are given for symptomatic and asymptomatic intact women and are comparable to previously reported endoanal MRI and ultrasound measurements.

Postpartum genitourinary changes.

Genitourinary changes following childbirth and pregnancy are common, and include urinary and anal incontinence, pelvic pain, sexual dysfunction, and pelvic organ prolapse. At present, it is unclear whether or not these changes are a result of the pregnancy itself or the mode of delivery (cesarean section or vaginal birth). In this article, the authors aim to describe genitourinary postpartum pelvic floor changes, and review the literature regarding the impact of pregnancy or childbirth on these changes. Data is needed that compare the effects of pregnancy alone, cesarean delivery (labored and unlabored), and vaginal birth, so that physicians can better advise patients about the postpartum genitourinary tract changes they might expect.

Evaluating the impact of overactive bladder on sexual health in women: what is relevant?

INTRODUCTION: To assess sexual health, relevant, valid, and reliable questionnaires need to be used. AIM: To assess the relevance and content validity of three sexual health questionnaires in women with overactive bladder (OAB) and urinary incontinence. MAIN OUTCOME MEASURES: Sexual Quality of Life Questionnaire--Female (SQoL-F), Sexual Function Questionnaire (SFQ), and Pelvic Organ Prolapse-Incontinence Sexual Function Questionnaire (PISQ). METHODS: Women with OAB and urinary incontinence were recruited from five urology clinics in the United States; those who were interested in participating were mailed questionnaire packets with instructions. Each questionnaire item was followed by three questions regarding the understandability, relevance, and impact of bladder condition when responding to the question. Patients returned the completed questionnaires by mail; clinical information was obtained from chart review. RESULTS: A total of 129 patients (74% response) returned the questionnaires. The mean age was 56 years; 78% were white; 64% were married. In this sample, 64% had urge incontinence; 32% had mixed incontinence; and 4% had stress incontinence. Participants experienced bladder symptoms for a mean of 12.2 years with the following treatments: surgery (43%), bladder training (26%), exercise/biofeedback (42%), and medications (67%). SQoL-F items were understood by more than 97% of the respondents, more than 89% for SFQ, and more than 82% for PISQ. There were two SQoL-F items, one SFQ item, and 11 PISQ items that less than 60% of the respondents deemed relevant to their bladder condition. Correlations among questionnaire items and relevance to bladder condition ranged from 0.04 to 0.64 for the SQoL-F, 0.04 to 0.47 for the SFQ, and 0.01 to 0.58 for the PISQ. CONCLUSION: Women with OAB found the majority of items on all three questionnaires to be relevant to their bladder condition. Of these questionnaires, the SQoL-F had the highest understandability, fewest questions considered irrelevant, and correlated well with OAB symptoms.

Lifelong learning and the reconstructive pelvic surgeon.

Many challenges face practicing surgeons in today's medical environment. Decreasing revenues create a need for increasing patient volume. Increasing costs of malpractice insurance not only provide financial burdens, but also cause many practitioners to relocate or change the focus of their practice. Technological advancements with the rapid emergence of new procedures and medical devices tax the practicing physician's ability to keep apace of changes. These changes, in combination with increased focus on patient safety and physician competence, place even greater demands on practicing in the surgical subspecialties. In this environment, finding time to improve skills and gain competence in new procedures is a daunting task. This article addresses the topic of surgical competence, provides insight into how to learn to do and prove competence to perform new surgical procedures, as well as reviews the opportunities available for self-evaluation currently available for the practicing surgeon.

A comparison of periurethral blood flow resistive indices and urethral closure pressure of incontinent women.

This study correlated Doppler resistive indices (RIs) with maximum urethral closure pressures (MUCPs) in women with stress urinary incontinence. We hypothesized that urethral blood flow would be inversely correlated to urethral closure pressures. Fifty-three women underwent spectral Doppler waveform analyses of periurethral vasculature to calculate RI. Urethral morphology including pubovesicular length (PVL) with and without cough was measured. MUCPs were obtained according to International Continence Society guidelines. Physical exam and history were also obtained. Correlation coefficients were calculated for comparisons of Doppler measurements and closure pressures. Fifty patients were required to detect a difference between no correlation and a modest correlation of 0.38 with 80% power and alpha of 0.05. Significance is set at p<0.05. Measurements were reproducible between Doppler waveforms and MUCP measurements (all p=NS). RI was not correlated with age, parity, MUCP, Incontinence Impact Questionnaire-7 scores, urethral length, or urethral width (all p=NS). RI and MUCP were likewise not associated with history of diabetes, hypertension, or anterior vaginal prolapse to or beyond the hymen (all p=NS). MUCP was negatively correlated with age (r=-0.33, p=0.01) even when controlled for hormonal status (ANCOVA, p=0.003) and positively correlated with urethral/bladder neck diameter (r=27, p=0.05), PVL (r=0.30, p=0.03), and PVL with cough (r=0.36, p=0.009).

Does sexual function change after surgery for stress urinary incontinence and/or pelvic organ prolapse? A multicenter prospective study.

OBJECTIVE: The purpose of this study was to assess sexual function in women after surgery for stress urinary incontinence and/or pelvic organ prolapse (UI/POP) at 3 and 6 months with the Pelvic Organ Prolapse Urinary Incontinence Sexual Questionnaire (PISQ). STUDY DESIGN: Of 269 eligible women participating in a trial of prophylactic antibiotic use with suprapubic catheters, 102 (37.9%) agreed to participate in a sexual function study. Women underwent a variety of anti-incontinence and reconstructive surgeries. Sexual function and urinary incontinence were assessed preoperatively and at 3 and 6 months, postoperatively, with the PISQ and Incontinence Impact Questionnaires (IIQ-7). Paired t tests compared changes over time. Logistic regression compared worsening PISQ versus other variables. Generalized McNemar test compared individual questions preoperatively and postoperatively. Significance was set at P < .05. RESULTS: Mean age was 47.1 (23-85) years, and 64% of women were premenopausal. Seventy-five (74%) women completed questionnaires at 3 or 6 months. Sexual function scores improved after surgery as did IIQ-7 scores (PISQ 89 vs 95, P < .001; IIQ-7 = 52 vs 13, P < .001). The Behavioral Emotive domain scores did not change at 3 to 6 months compared with preoperative scores P = .57), whereas the Physical domain improved (P < .001). Worsening PISQ scores were independent of age, type of surgery, hysterectomy, complications, or hormonal status (logistic regression, all P < .05). CONCLUSION: Sexual function scores in women improve after surgery for UI/POP as did improvement of incontinence at 3 to 6 months after surgery.

Teaching and evaluating ultrasound skill attainment: competency-based resident ultrasound training for AIUM accreditation.

Modern obstetrics and gynecology practice requires the frequent use of ultrasound and ultrasound training as a required component of obstetrics and gynecology residencies. Although programs do offer training in obstetric ultrasound imaging, education in gynecologic imaging is either absent or limited. This article describes a comprehensive ultrasound curriculum for obstetrics and gynecology residents that has been developed and implemented at the University of New Mexico. The curriculum is competency based and qualifies the graduating resident to seek American Institute of Ultrasound in Medicine laboratory accreditation.

Mental practice and acquisition of motor skills: examples from sports training and surgical education.

Learning surgical skills involves both fine and gross motor skills, and necessitates performance in stressful situations. This environment is similar to the environment in which an athlete performs. Mental imagery has been used successfully in training athletes of all levels of proficiency and enhances both motor skills and motivational skills of performing under stress. The literature of using mental imagery to train surgeons is limited to the teaching of simple surgical skills, but shows promise as another tool to teach technical skills.

Primary repair of obstetric anal sphincter laceration: a randomized trial of two surgical techniques.

OBJECTIVE: This study was undertaken to compare surgical techniques for the primary repair of obstetric anal sphincter lacerations. STUDY DESIGN: Patients with complete third- or fourth-degree lacerations were recruited and randomly assigned to either an end-to-end or overlapping repair. Data collection included demographic data, obstetric history, and intrapartum events. Postpartum, women completed incontinence questionnaires and underwent physical and ultrasound examinations. To detect a 36% difference between groups with an alpha = .05 and beta = .20, 30 patients were required. Data were analyzed with Student t test and chi2 analysis. RESULTS: Forty-one women were randomly assigned; 23 to an end-to-end and 18 to an overlapping repair. Twenty-seven percent of women underwent episiotomy and 61% operative vaginal delivery. Follow-up was limited to 26 of 41 patients. On physical examination, 3 patients had a separated anal sphincter. On ultrasound, overall 85% of patients had intact sphincters, with no difference between groups (all P > .05). Forty-two percent of women complained of anorectal symptoms with no differences between groups (all P > .28). CONCLUSION: We found no difference in anal incontinence symptoms, physical examination, or translabial ultrasonography findings between the 2 groups. Incontinence symptoms were common in both groups.

Diabetes and urinary incontinence in 50- to 90-year-old women: a cross-sectional population-based study.

OBJECTIVE: The purpose of this study was to examine the association between urinary incontinence and diabetes in a large community-based population of women. STUDY DESIGN: The Health and Retirement Study is a large multistage area probability sample of households in the United States. Data were collected from 10,678 women aged 50 to 90 years. Dependent variables were no, mild, and severe incontinence. Independent variables consisted of demographic and health data. Diabetes was dichotomized into insulin-requiring (IRDM) and non-insulin-requiring disease (NIRDM). Survey-based ordered logistic regression was used to simultaneously analyze associations between incontinence groups. RESULTS: Urinary incontinence was reported by 22% (2319/10,678) of women. IRDM was associated with urinary incontinence (odds ratio [OR] 1.63; 95% CI 1.28-2.09), but NIRDM was not (OR 1.20; 95% CI 1.00-1.45). CONCLUSION: IRDM is independently associated with urinary incontinence in women ages 50 to 90 years, independent of patient body mass index, comorbidities, or age.

Significance was set at P <.05. RESULTS: Mean age was 47.1 (23 to 85) years, and 64% of women were premenopausal. Seventy-five (74%) women completed questionnaires at 3 or 6 months. Sexual function scores declined after surgery despite improvement in IIQ-7 scores (PISQ=86 vs 78, P <.001; IIQ-7=52 vs 13, P <.001). Behavioral Emotive domain scores worsened at 3 to 6 months compared with preoperative scores, while the Physical domain improved (all P <.001). Worsening PISQ scores were independent of age, type of surgery, hysterectomy, complications, or hormonal status (logistic regression, all P <.05). CONCLUSION: Sexual function scores in women after surgery for UI/POP do not improve despite improvement of incontinence at 3 to 6 months after surgery.

A randomized, double-blind, placebo-controlled comparison of the effect of nitrofurantoin monohydrate macrocrystals on the development of urinary tract infections after surgery for pelvic organ prolapse and/or stress urinary incontinence with suprapubic catheterization.

OBJECTIVE: The purpose of this study was to determine if antibiotic prophylaxis with nitrofurantoin monohydrate macrocrystals (study drug) after pelvic organ prolapse and/or urinary incontinence surgery with suprapubic catheterization (SPC) decreases urinary tract infection (uti) compared with placebo in a randomized, double-blind, multicenter trial. STUDY DESIGN: Six centers participated in this study. After a negative preoperative urine culture, history, surgical and postoperative course, urine culture and symptoms at SPC removal, and at 6 to 8 weeks postoperative, any other UTI and adherence were recorded. To demonstrate a 50% decrease in the bacteruria rate from 20%, with 80% power and alpha of 0.05, 438 patients were required. Data were evaluated with Student t test and Fisher exact test. RESULTS: Of 449 patients enrolled, 211 randomized to study drug, and 224 randomized to placebo. No pre- or perioperative differences existed between groups (all P>.05). Antibiotic prophylaxis decreased positive urine cultures compared with placebo (46% vs 61%, P=.002), symptomatic UTI at SPC removal (7.2% vs 19.8%, P=.001), and any other symptomatic UTI 6 to 8 weeks postoperatively (18.9% vs 32.6%, P=.002). Antibiotic prophylaxis did not decrease symptomatic UTI at the 6- to 8-week postoperative visit (1.8% vs 5.4%, P=.10). CONCLUSION: Antibiotic prophylaxis with nitrofurantoin monohydrate macrocrystals decreases UTI compared with placebo after pelvic organ prolapse and/or urinary incontinence surgery with suprapubic catheterization.

A short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12).

The aim of this study was to develop the short form of a condition-specific, reliable, validated and self-administered instrument to evaluate sexual function in women with pelvic organ prolapse and/or urinary incontinence. The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire -12 (PISQ-12) was developed from the data of 99 of 182 women surveyed to create the long form (PISQ-31). An additional 46 patients were recruited for further validation. All subsets regression analysis identified 12 items likely to predict PISQ-31 scores. Short form scores underwent correlation analysis with long form, Incontinence Impact Questionnaire - 7 (IIQ-7), Sexual History Form -12 (SHF-12) and Symptom Questionnaire (SQ) scores. Test-retest reliability was checked with a subset of 20 patients. All subsets regression analysis with R>0.92 identified 12 items that predicted PISQ-31 scores. Short form scores were highly correlated with long form scores ( R=0.75-0.95). Correlations of the PISQ-12 with SHF-12 ( R=-0.66 and -0.68) and IIQ-7 ( R=-0.38 and -0.54) scores were similar to correlation of the PISQ-31 with these other measures. Reliability was moderate to high, with weighted kappa values from 0.56 to 0.93. PISQ-12 scores were lower in patients with low sexual function as measured on the SHF-12 ( P <0.001), and lower in women with depression as measured on the SQ ( P <0.001). The PISQ-12 is a validated and reliable short form that evaluates sexual function in women with urinary incontinence and/or pelvic organ prolapse and predicts PISQ-31 scores. It is able to distinguish women with poor sexual function as measured on the SHF-12.

Abdominal hysterectomy for the enlarged myomatous uterus compared with vaginal hysterectomy with morcellation.

OBJECTIVE: The purpose of this study was to compare intraoperative and postoperative complications of abdominal hysterectomy for the enlarged, myomatous uterus with vaginal hysterectomy with morcellation. STUDY DESIGN: Medical records of 139 patients who underwent vaginal hysterectomy with morcellation and 244 patients who underwent total abdominal hysterectomy for an enlarged, myomatous uterus between August 1990 and July 2001 were reviewed. Uterine weights of >982 g were excluded because this was the largest uterus removed vaginally, which left 208 evaluable cases of total abdominal hysterectomy. The perioperative and postoperative course of the two groups was compared. The Student t test was used for continuous variables, and the Fisher exact test was used for binary or categoric data. RESULTS: There were no significant differences between the two groups in surgical or anesthetic risk factors (P>.05). Operative time was similar between the groups (P>.05). Length of hospital stay was increased significantly with total abdominal hysterectomy (mean, 3.9 days vs 2.6 days; P<.001). Perioperative complications were increased with the abdominal route (10% vs 25%, P<.001). CONCLUSION: In this large series, uterine morcellation at the time of vaginal hysterectomy is safe and facilitates the removal of moderately enlarged and well-supported uteri and is associated with decreased hospital stay and perioperative morbidity rate compared with the abdominal route.

Predictors of successful pessary fitting and continued use in a nurse-midwifery pessary clinic.

Women with incontinence and/or pelvic organ prolapse presenting to an urogynecology service were offered referral to a dedicated midwifery pessary clinic. Charts of these women were reviewed for demographic information, physical examination, pelvic floor disorders, and details of pessary-fitting sessions. Successful fitting was defined as a comfortable fit and retention of the pessary with valsalva and voiding. Continuation was defined as a successfully fit patient who returned at least once after the initial fitting with the pessary still in use. Spearman's correlations identified variables associated with successful fitting and continuation of use. Logistic regression identified variables that predicted continued use. Eighty-six percent of women were successfully fit, and 89% continued pessary use for a mean of 6 months. Predictors of unsuccessful fitting included a history of a prior prolapse procedure or hysterectomy (P < or = .001). Severe posterior prolapse was associated with pessary discontinuation after adjustment for patient's age (P < .04). Success rates for treatment of stress urinary incontinence, pelvic organ prolapse, or both were not significantly different (success rates of 94%, 89%, and 81%, respectively; P = .50). Predictors of unsuccessful pessary fitting include history of a prior prolapse procedure and hysterectomy. Severe posterior prolapse was the single predictor of pessary discontinuation.
