A comparison of costs for abdominal, laparoscopic, and robot-assisted sacral colpopexy

The aim of this study was to compare the short-term estimated hospital costs and charges for open, laparoscopic, and robot-assisted sacral colpopexy. The null hypothesis was that there would be no difference in costs and charges. Fifteen comparable cases were reviewed for demographics, surgical information, and estimated hospital charges and costs and then compared with analysis of variance. There were no differences in demographics and surgical variables among the three groups. For estimated hospital charges, minimally invasive sacral colpopexy was most expensive; open was the least expensive approach. The estimated direct costs were significantly higher for robot-assisted compared with open sacral colpopexy, but not different between robot-assisted and laparoscopic sacral colpopexy. Robot-assisted sacral colpopexy produces the highest estimated hospital charges and is more expensive than open sacral colpopexy. The least expensive surgical approach from the hospital costs perspective is open abdominal sacral colpopexy.

Difference in quality of life in women with urge urinary incontinence compared to women with stress urinary incontinence

IntroductionWe evaluated whether women with urge urinary incontinence (UUI) have lower quality of life (QOL) than women with other forms of urinary incontinence.MethodsPatients completed three validated questionnaires when presenting for evaluation at a urogynecology practice and were divided into four groups based on their responses: those with symptoms of stress urinary incontinence (SUI), UUI, both SUI and UUI (mixed UI), and neither SUI nor UUI (controls).ResultsA total of 465 women were included: 53 women with UUI (11.4%), 101 with SUI (21.7%), 200 with mixed UI (43%), and 111 controls (23.9%). Overall, there was a significant difference (p < 0.001) in PFIQ bladder scale scores as a function of UI group, with individual mean PFIQ scores of 17.1 for controls, 22.3 for SUI, 32.7 for UUI, and 36.8 for mixed UI. Individually, all seven questions in the PFIQ bladder domain were significantly different by group (p ≤ 0.001).ConclusionsWomen with UUI and mixed UI have lower QOL scores than women without incontinence or with only SUI.

Resident education and training in urogynecology and pelvic reconstructive surgery: a survey

The aim of the study is to assess satisfaction with urogynecology education among obstetrics and gynecology residents. An Internet-based survey was designed to obtain a cross-sectional sample of third- and fourth-year residents. Didactic and surgical training as well as perceived surgical competency were assessed. Responses were received from 205 residents for this convenience sample. Nearly half (46%) of the respondents were unsatisfied with urogynecology resident education. There was no significant difference between respondents from academic programs and community programs with regard to overall satisfaction, the opportunity to work with the presence of a fellowship-trained urogynecologist or having a dedicated urogynecology rotation. Respondents were more satisfied with their education if they did a urogynecology rotation or worked with a fellowship-trained urogynecologist. Female pelvic medicine and reconstructive surgery fellows were involved in the education of 23.9% of the respondents. Most respondents indicated comfort performing cystoscopy, anterior and posterior repairs, and McCall’s culdoplasty following graduation. Overall, respondents indicated that residency training in urogynecology is less and later than desired, although they did feel competent at some urogynecologic surgeries.

Anterior vaginal wall prolapse and voiding dysfunction in urogynecology patients

We investigated whether women with and without anterior vaginal wall prolapse have voiding differences. Women (n = 109) who presented to a urogynecology practice were categorized into two groups based on anterior vaginal wall prolapse: stages 0 and 1 and stages 2, 3, and 4. Women with prolapse were older than the women without prolapse but the groups were otherwise similar demographically. There was a higher rate of activity-related urine loss and use of wetness protection amongst women without prolapse. There was no significant difference for urgency symptoms or urge incontinence. Urodynamic testing found no significant differences for maximal flow rate or maximal urethral closing pressures. Postvoid residual volume and detrusor overactivity were not different but approached significance. Anterior vaginal wall prolapse of stage 2 or greater was not associated with urge incontinence or voiding function in this population. Women without prolapse were more likely to report stress incontinence.

Use of a beef tongue model and instructional video for teaching residents fourth-degree laceration repair

Introduction and hypothesisThis study seeks to compare the utility of the beef tongue model versus an instructional video in teaching obstetric and gynecology residents how to repair a fourth-degree laceration.MethodsTwenty-seven residents were randomized to participate in a workshop with a beef tongue model or assigned to watch an instructional video on repair of fourth-degree lacerations and read a chapter on the repair. All subjects were tested with a pre- and postintervention written test. These scores were compared with paired t test at 0.05 significance level.ResultsResidents with no prior experience in fourth-degree laceration repairs showed an improvement in knowledge (49.5% versus 64.1%, p < 0.001) on written exams about the repairs.ConclusionsAn instructional video or beef tongue model and textbook chapter on fourth-degree laceration repair can improve skills in repair of a fourth-degree laceration among residents with no experience in these repairs.

The effect of pessaries on the vaginal microenvironment

OBJECTIVE The objective of the study was to evaluate the differences in vaginal culture, microscopy, and Gram stain between postmenopausal women who wear pessaries and those who do not to explain pessary-related, bothersome vaginal discharge. STUDY DESIGN Postmenopausal women not using exogenous estrogen who had either been wearing a pessary for at least 3 months or who were undergoing their first pessary fittings were approached for enrollment. Symptoms were assessed, and vaginal fluid was collected for culture, microscopy, and Gram stain. A cross-sectional analysis was performed, comparing the new and return pessary wearers. The new pessary users were also sampled at 2 weeks, 3 months, and 6 months after fitting. RESULTS Women who wore pessaries were more likely to be bothered by discharge (30.0% vs 2.1%, P < .001). They were also more likely to show microscopic evidence of vaginal inflammation and vaginitis. Prospective data showed that these changes developed during the first 2 weeks of pessary use. Aerobic and anaerobic organisms were nearly identical in women with and without bothersome vaginal discharge in the cross-sectional analysis and at all time points in the prospective analysis. CONCLUSION Pessary-related, bothersome vaginal discharge develops early and may be due to an inflammatory process in the vagina.

Coronary artery vitamin D receptor expression and plasma concentrations of 25-hydroxyvitamin D: their association with atherosclerosis.

Objective The aim of this study was to analyze coronary artery vitamin D receptor (VDR) expression, the plasma concentrations of 25-hydroxyvitamin D3 (25OHD3), and their relationship with coronary artery atherosclerosis. Methods Premenopausal cynomolgus monkeys were fed atherogenic diets containing the equivalent of 1,000 IU/day of vitamin D3. Protein was derived from casein-lactalbumin (C/L, n = 10), soy protein isolate (soy, n = 10), or a combination (n = 19). After 32 months of consuming the diets, each monkey underwent surgical menopause. After 32 postmenopausal months, coronary atherosclerosis was measured in the left circumflex (LCX) artery and left anterior descending (LAD) artery. VDR expression was determined for the LAD, and 25OHD3 concentrations were assessed. Results Both the cross-sectional area of atherosclerotic plaques (in square millimeters) and plaque thickness (in millimeters) in the LCX as well as the LAD arteries were analyzed in these monkeys. Those with higher plasma vitamin D3 concentrations and higher VDR were compared with those with higher plasma 25OHD3 concentrations and lower VDR. Significantly smaller plaque sizes were noted with higher plasma 25OHD3 concentrations and higher VDR. For the LCX artery, there was also a significantly lower plaque size (both plaque thickness and cross-sectional area) in those with higher quantities of VDR and lower 25OHD3 concentrations versus those with lower quantities of VDR and higher plasma concentrations of 25OHD3 (P = 0.009 and P = 0.040, respectively). Conclusions Cynomolgus monkeys with higher quantities of VDR have significantly less atherosclerosis than do those with lower quantities of VDR and higher plasma 25OHD3 concentrations. If these findings translate to human beings, it might explain why some individuals with higher plasma concentrations of 25OHD3 have more coronary artery atherosclerosis.

Is Burch or mid-urethral sling better with abdominal sacral colpopexy?

Introduction and hypothesisThis study aims to compare the post-operative rates of stress urinary incontinence (SUI) after abdominal sacral colpopexy (ASC) with either Burch or mid-urethral sling, tension-free vaginal tape (TVT), or no anti-incontinence procedure. The null hypothesis was there would be no difference in SUI among groups.MethodsA cohort of women who had undergone ASC (n = 150) either alone or with an anti-continence procedure were analyzed to determine the rates of post-operative SUI. Statistically significant differences were evaluated with a Student’s t-test.ResultsA total of 150 subjects were evaluated, with 115 having SUI preoperatively. Post-operatively, 10% (15/150) of all subjects had SUI. Subjects with preoperative SUI who had a Burch were more likely to have post-operative SUI than those who had a TVT (10 versus 0, p = 0.007).ConclusionsBurch and TVT procedures improve SUI symptoms in patients undergoing ASC. Mid-urethral slings performed with ASC have lower rates of post-operative SUI.

Correlation of POP-Q posterior compartment measures with defecatory dysfunction

Introduction and hypothesisThe relationships of Pelvic Organ Prolapse Quantification (POP-Q) items pb and Bp with defecatory dysfunction were evaluated with the hypothesis that increased values for both items would correlate with symptoms of stool trapping.MethodsPelvic Floor Distress Inventory (PFDI-20) results and POP-Q exams from 1,663 urogynecology patients were compiled in a database. Rectocele was defined as POP-Q point Bp > −0.5 and perineocele as pb >3. PFDI-20 questions were used to compare defecatory symptoms and bother in women with and without rectocele and perineocele.ResultsWhile perineocele was not associated with symptoms or bother, women with isolated rectoceles had higher rates of splinting (p < 0.001) and incomplete evacuation (p = 0.001) and higher bother scores (p < 0.001) than those with neither rectocele nor perineocele.ConclusionsThe POP-Q Bp point, but not the pb measurement, correlates with symptoms of defecatory dysfunction.

Factors associated with PISQ-12 completion in an academic urogynecology population

Introduction and hypothesisSome new urogynecology patients who are given the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12) complete it despite stating that they are not sexually active. This study compared sexually active (SA) and non-sexually active (NSA) women who complete the PISQ-12, hypothesizing that these groups differ substantially.MethodsNew patients during the study period were given the PISQ-12 and two other validated questionnaires. Medical and demographic data were collected and analyzed for univariate differences between SA and NSA PISQ-12 completers. Logistical regression identified factors predicting PISQ-12 completion.ResultsOf the 655 new patients during the study period, 399 completed the PISQ-12. Of these, 16.8% were NSA. These women were older, less likely married, and had higher BMI than their SA counterpart. Being sexually active, younger, and married are predictors of PISQ-12 completion.ConclusionsSome NSA women complete the PISQ-12. Instructions should specify that only SA women complete this questionnaire.
