Effects of vaginal conjugated equine estrogens and ospemifene on the rat vaginal wall and lower urinary tract.

Although the positive effects of vaginal estrogens and the selective estrogen receptor modulator, ospemifene (OS), on the vaginal epithelium are well recognized, less is known regarding the effects of these therapies on the lower urinary tract or vaginal muscularis. Clinical evidence suggests that vaginally administered estrogen may improve overactive bladder-related symptoms. The objective of this study was to compare the effects of OS, vaginal conjugated equine estrogens (CEE), or both on the vaginal wall and lower urinary tract in a rat model of menopause. Contractile force of the bladder neck, dome, and external urethral sphincter at optimal field stimulation did not differ significantly among treatment groups. Pharmacologic responses to atropine, carbachol, and potassium chloride were similar among groups. Vaginal epithelial thickness and differentiation were differentially regulated by CEE or OS. Ospemifene altered epithelial differentiation pathways in vaginal epithelium in a unique way, and these effects were additive with local CEE. Unless contraindicated, the beneficial effects of vaginal CEE on the vaginal wall outweigh those of OS.

Effect of vaginal or systemic estrogen on dynamics of collagen assembly in the rat vaginal wall.

The objective of this study was to compare the effects of systemic and local estrogen treatment on collagen assembly and biomechanical properties of the vaginal wall. Ovariectomized nulliparous rats were treated with estradiol or conjugated equine estrogens (CEEs) either systemically, vaginal CEE, or vaginal placebo cream for 4 wk. Low-dose local CEE treatment resulted in increased vaginal epithelial thickness and significant vaginal growth without uterine hyperplasia. Furthermore, vaginal wall distensibility increased without compromise of maximal force at failure. Systemic estradiol resulted in modest increases in collagen type I with no change in collagen type III mRNA. Low-dose vaginal treatment, however, resulted in dramatic increases in both collagen subtypes whereas moderate and high dose local therapies were less effective. Consistent with the mRNA results, low-dose vaginal estrogen resulted in increased total and cross-linked collagen content. The inverse relationship between vaginal dose and collagen expression may be explained in part by progressive downregulation of estrogen receptor-alpha mRNA with increasing estrogen dose. We conclude that, in this menopausal rat model, local estrogen treatment increased total and cross-linked collagen content and markedly stimulated collagen mRNA expression in an inverse dose-effect relationship. High-dose vaginal estrogen resulted in downregulation of estrogen receptor-alpha and loss of estrogen-induced increases in vaginal collagen. These results may have important clinical implications regarding the use of local vaginal estrogen therapy and its role as an adjunctive treatment in women with loss of vaginal support.

Risk factors for ureteral occlusion during transvaginal uterosacral ligament suspension.

INTRODUCTION AND HYPOTHESIS: To determine any risk factors associated with ureteral occlusion during transvaginal uterosacral ligament suspension (USLS). METHODS: A retrospective query to identify patients that underwent transvaginal USLS at a teaching hospital from 2008 to 2013 was performed. Patients in which ureteral occlusion was identified by cystoscopy were identified (cases), and compared with those without occlusion (controls). Medical records were reviewed for data abstraction. Variables compared between cases and controls included demographics, medical history/examination, concomitant procedures, number of suspension sutures placed, estimated blood loss and length of hospital stay. Univariate analyses were performed to identify potential risk factors for ureteral occlusion, followed by multivariate regression analysis to estimate odds ratios for identified predictors. RESULTS: A total of 144 USLS procedures were performed. Thirteen cases of ureteral occlusion were identified (9%). Baseline prolapse stage, body mass index, parity, previous hysterectomy or pelvic surgery of the groups were similar (all P > 0.05). Univariate analysis identified age (P = 0.04), concomitant anterior colporrhaphy (P = 0.01), and use of a suture-capturing device for suture placement (P = 0.04) as significant factors. On multivariate logistic regression analysis, concomitant anterior colporrhaphy increased ureteral occlusion risk (OR 10.5, 95%CI 2.37-74.99, P = 0.001), while use of a suture-capturing device decreased it (OR 0.1, 95%CI 0-0.41, P = 0.01). The mean number of suspension sutures placed per side was similar in the two groups (2.6 [range 2-4] for cases and 2.4 [range 1-4] for controls, P = 0.15). CONCLUSIONS: During transvaginal USLS, performance of a concomitant anterior colporrhaphy increased the risk of ureteral occlusion, while the use of a suture-capturing device for suspension suture placement was associated with decreased risk.

Myogenic stem cell-laden hydrogel scaffold in wound healing of the disrupted external anal sphincter.

OBJECTIVE: To evaluate the effect of myogenic stem cell-laden hydrogel scaffold on contractile function and histomorphology of the external anal sphincter (EAS) after transection without repair. METHODS: Eighty female rats underwent anal sphincter transection without repair. After 2 weeks, animals were injected at the transection site with: nothing (non-repaired control, NRC group); a polyethylene glycol-based hydrogel matrix scaffold combined with phosphate-buffered saline (PBS/hydrogel group); a hydrogel matrix scaffold combined with myogenic stem cells (stem cell/hydrogel group): or type I collagen (collagen) group. 4 (n = 40) or 12 (n = 40) weeks later, the anal sphincter complexes were dissected out and analyzed for contractile function, disruption, and striated muscle volume. Time-matched unoperated controls (UOC) were utilized for each of the two time points (n = 20). RESULTS: After 4 weeks, maximal electrical field-stimulated (EFS) contractions were significantly decreased in all four non-repaired treatment groups compared with UOC. However, EFS-stimulated contractions, tetanic force generation, and twitch tension were improved in non-repaired EAS injected with stem cell/hydrogel group relative to the NRC, PBS/hydrogel, or collagen groups. NRC and sphincters injected with PBS/hydrogel deteriorated further by 12 weeks, while those receiving stem cell/hydrogel maintained improved contractile function at varying frequencies and voltages. Striated muscle volume increased from 4 to 12 weeks for PBS/hydrogel and stem cell/hydrogel animals. At 12 weeks, stem cell/hydrogel animals had greater sphincter striated muscle volumes compared with all other treatment groups. CONCLUSION: In this animal model, sustained improvement of contractile responses in non-repaired EAS treated with biogel scaffold and myogenic stem cells suggests that a biologically compatible matrix may facilitate stem cell survival, differentiation, or function leading to recovery of contractile function even after persistent disruption.

Venous thromboembolism in women undergoing pelvic reconstructive surgery with mechanical prophylaxis alone.

INTRODUCTION AND HYPOTHESIS: The objective of this study was determine the frequency of symptomatic perioperative venous thromboembolism (VTE) and risk factor(s) associated with VTE occurrence in women undergoing elective pelvic reconstructive surgery using only intermittent pneumatic compression (IPC) for VTE prophylaxis. METHODS: A multi-center case-cohort retrospective review was conducted at six clinical sites over a 66-month period. All sites utilize IPC as standard VTE prophylaxis for urogynecological surgery. VTE cases occurring during the same hospitalization and up to 6 weeks postoperatively were identified by ICD9 code query. Four controls were temporally matched to each case. Information collected included demographics, medical history, route of surgery, operative time, and intraoperative characteristics. Univariate and multivariate backward stepwise logistic regression analyses were performed to identify potential risk factors for VTE. RESULTS: Symptomatic perioperative VTE was diagnosed in 27 subjects from a cohort of 10,627 women who underwent elective urogynecological surgery (0.25 %). Univariate analysis identified surgical route (laparotomy vs others), type of surgery ("major" vs "minor"), history of gynecological cancer, surgery time, and patient age as risk factors for VTE (P < 0.05). Multivariate analysis identified increased frequency of VTE with laparotomy, age ≥ 70, and surgery duration ≥ 5 h. CONCLUSIONS: In our study cohort, the frequency of symptomatic perioperative VTE was low. Laparotomy, age ≥ 70 years, and surgery duration ≥ 5 h were associated with VTE occurrence.

Aversion to Mesh Use in Pelvic Floor Surgery in a Latina Population at the U.S.-Mexico Border.

IMPORTANCE: Limited studies have examined patient aversion to mesh use in pelvic surgery, especially in Latinas. OBJECTIVE: This study aimed to assess aversion to pelvic surgery with mesh for urinary incontinence and pelvic organ prolapse in a sample of Latinas on the U.S.-Mexico border. STUDY DESIGN: This was a cross-sectional study of self-identified Latinas with symptoms of pelvic floor disorders, recruited at their initial consultation visit at a single, academic urogynecology clinic. Participants completed a validated survey to assess perceptions of mesh use in pelvic surgery. Participants also completed questionnaires assessing the presence and severity of pelvic floor symptoms and level of acculturation. The primary outcome was aversion to mesh surgery, as indicated by a response of "yes" or "maybe" to the question "Based on what you already know, would you avoid surgery using mesh?" Descriptive analysis, univariate relative risk, and linear regression analysis were completed to identify characteristics associated with mesh avoidance. Significance was assessed and considered at P values <0.05. RESULTS: Ninety-six women were included. Only 6.3% had prior pelvic floor surgery using mesh. Sixty-six percent indicated that they would be likely to avoid pelvic surgery that uses mesh. Only 9.4% indicated that they obtained information regarding mesh directly from medical professionals. Levels of concern regarding the use of mesh varied widely (29.2% not worried, 19.1% somewhat worried, 16.9% very worried). Higher percentages of "more acculturated" participants indicated a desire to avoid mesh surgery (58.7% vs 27.3%, P < 0.05). CONCLUSIONS: In this Latina population, a majority of patients indicated an aversion to using mesh in pelvic surgery. Few patients obtained information regarding mesh directly from medical professionals, relying instead on nonmedical sources.

Estrogen alters remodeling of the vaginal wall after surgical injury in guinea pigs.

Loss of pelvic organ support (i.e., pelvic organ prolapse) is common in menopausal women. Surgical reconstruction of pelvic organ prolapse is plagued with high failure rates. The objective of this study was to determine the effects of estrogen on biomechanical properties, lysyl oxidase (LOX), collagen content, and histomorphology of the vagina with or without surgical injury. Nulliparous ovariectomized guinea pigs were treated systemically with either 50 µg/kg/day estradiol (E2,) or vehicle. After 2 wk, vaginal surgery was performed, and animals were treated with either beta-aminopropionitrile (BAPN, an irreversible LOX inhibitor), or vehicle to determine the role of LOX in recovery of the vaginal wall from injury with or without E2. Estradiol resulted in (i) significant growth, increased smooth muscle, and increased thickness of the vagina, (ii) increased distensibility without compromise of maximal force at failure, and (iii) increased total and cross-linked collagen. In the absence of E2, BAPN resulted in decreased collagen and vaginal wall strength in the area of the injury. In contrast, in E2-treated animals, increased distensibility, maximal forces, and total collagen were maintained despite BAPN. Interestingly, LOX mRNA was induced dramatically (9.5-fold) in the injured vagina with or without E2 at 4 days. By 21 days, however, LOX levels declined to near baseline in E2-deprived animals. LOX mRNA levels remained strikingly elevated (12-fold) at 21 days in the estrogenized vagina. The results suggest that prolonged E2 induced increases in LOX, and collagen cross-links may act to sustain a matrix environment that optimizes long-term surgical wound healing in the vagina.

Anatomic relationships of single-incision midurethral slings.

OBJECTIVE: The objective of the study was to evaluate the anatomic relationships of anchor points of single-incision midurethral slings with 2 common placement trajectories. STUDY DESIGN: In 30 female pelvic halves, a probe was introduced through a suburethral tunnel following 45° and 90° angle trajectories. The corresponding anchor points were tagged. Distances to the obturator canal, accessory obturator vessels, dorsal vein of clitoris, and external iliac vein were recorded. RESULTS: Both suburethral tunnel trajectories and their respective anchor points remained caudad to the obturator internus muscle in 100% of dissections. The closest distance between either anchor point to the obturator canal was 1.6 cm. The closest distance from the 45° and 90° anchor points to the accessory obturator vessels was 1.6 and 1.5 cm, respectively. CONCLUSION: The anchor points of single-incision midurethral slings are in close proximity to vascular structures that could be injured with inadvertent entry into the retropubic space.

Functional and anatomic comparison of 2 versus 3 suture placement for uterosacral ligament suspension: a cadaver study.

OBJECTIVE: The objective of the study was to compare the vaginal apex pullout distance using 2 vs 3 suspension sutures during transvaginal uterosacral ligament suspension (USLS) and to describe relationships to ipsilateral ureter and nerve structures. STUDY DESIGN: Eight fresh-frozen female cadavers were studied. After hysterectomy, a transvaginal USLS was performed with placement of 3 suspension sutures per side. The 2 most distal sutures on each ligament were tied. A screw-and-washer attachment was secured in the middle of the vaginal cuff and tied to a pulley system with surgical filament. Distal traction was applied with sequentially increasing weight loads. Distal migration of the vaginal apex from baseline with each weight load was recorded. The most proximal suspension suture was tied and the procedure repeated. Horizontal distances between each USLS suture to the ipsilateral ureter were measured. Three discrete points were marked on sacral nerves S1-S3, and the shortest distance between each point and each ipsilateral USLS suture was measured. Descriptive statistics and repeated-measures analysis of variance were performed. RESULTS: Application of each load resulted in greater migration distances for the 2 suture configuration when compared with 3 sutures (P < .05). Differences were greatest for the 3 kg load (mean ± SEM, 2.0 ± 0.2 vs 1.5 ± 0.1 cm, respectively). Distances to ipsilateral ureter between the 2 most cranial sutures were comparable (P > .05). The most cranial USLS suture was closest to sacral nerves S1-S3. CONCLUSION: In this cadaveric study, 3 USLS sutures provided more support to the vaginal apex than 2 sutures, although the absolute difference may not be clinically significant. The most cranial suture had the smallest distances to sacral nerves S1-S3.

Vascular and ureteral anatomy relative to the midsacral promontory.

OBJECTIVE: The objective of the study was to further characterize the vascular and ureteral anatomy relative to the midsacral promontory, a landmark often used during sacrocolpopexy, and suggest strategies to avoid complications. STUDY DESIGN: Distances between the right ureter, aortic bifurcation, and iliac vessels to the midsacral promontory were examined in 25 unembalmed female cadavers and 100 computed tomography (CT) studies. Data were analyzed using Pearson χ(2), unpaired Student t test, and analysis of covariance. RESULTS: The average distance between the midsacral promontory and right ureter was 2.7 cm (range, 1.6-3.8 cm) in cadavers and 2.9 cm (range, 1.7-5.0 cm) on CT (P = .209). The closest cephalad vessel to the promontory was the left common iliac vein, the average distance being 2.7 cm (range, 0.95-4.75 cm) in cadavers and 3.0 cm (range, 1.0-6.1 cm) on CT (P = .289). The closest vessel to the right of the promontory was the internal iliac artery, with the average distance of 2.5 cm (range, 1.4-3.9 cm) in cadavers and 2.2 cm (range, 1.2-3.9 cm) on CT (P = .015). The average distance from the promontory to the aortic bifurcation was 5.3 cm (range, 2.8-9.7 cm) in cadavers and 6.6 cm (range, 3.1-10.1 cm) on CT (P < .001). The average distance from the aortic bifurcation to the inferior margin of the left common iliac vein was 2.3 cm (range, 1.2-3.9 cm) in cadavers and 3.5 cm (range, 1.7-5.6 cm) on CT (P < .001). CONCLUSION: The right ureter, right common iliac artery, and left common iliac vein are found within 3 cm from the midsacral promontory. A thorough understanding of the extensive variability in vascular and ureteral anatomy relative to the midsacral promontory should help avoid serious intraoperative complications during sacrocolpopexy.

Effect of repeat acute injury on contractile function of the external anal sphincter in an animal model.

INTRODUCTION AND HYPOTHESIS: Our aim was to estimate the physiologic effects of early repeat transection and repair on the contractile properties of the external anal sphincter (EAS) in a rat model. METHODS: Eighty young female rats underwent anal sphincter transection and repair. After 7 days, they were randomized to repeat sphincter transection (injury-injury, n = 40) or sham operation (injury-sham, n = 40). Thereafter, the anal sphincter complex was dissected, mounted, and analyzed for contractile function 7 days, 21 days, 3 months, or 6 months after the second operation. Contractile function was also determined in 40 age-matched unoperated controls (n = 10 for each time point). Statistical analysis was performed using analysis of variance (ANOVA) with Tukey-Kramer adjustment for multiple testing. P ≤ 0.05 was considered significant. RESULTS: Although single injury (injury-sham) resulted in modest compromise of sphincter function, repeat injury (injury-injury) resulted in profound impairment of twitch tension, maximal tetanic responses, and maximal electrical-field stimulation (EFS) induced-force generation at 7 days. After single injury, parameters of contractile function returned to baseline uninjured levels by 21 days. In contrast, sphincter function remained reduced 21 days after repeat injury. Contractile function of sphincters from both injury-sham and injury-injury animals were no longer impaired at 3 and 6 months. CONCLUSION: In this animal model, repeat injury and repair of the EAS 7 days after the initial injury resulted in prolonged compromise of EAS function compared with single injury. Nevertheless, contractile function of the double-injured sphincter fully recovered with time, resulting in no long-term impairment.

Spanish translation and validation of four short pelvic floor disorders questionnaires.

INTRODUCTION AND HYPOTHESIS: Globally, Spanish is the primary language for 329 million people; however, most urogynecologic questionnaires are available in English. We set out to develop valid Spanish translations of the Questionnaire for Urinary Incontinence Diagnosis (QUID), the Three Incontinence Questions (3IQ), and the short Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7). METHODS: The TRAPD method (translation, review, adjudication, pretesting, and documentation) was used for translation. Eight native Spanish-speaking translators developed Spanish versions collaboratively. These were pretested with cognitive interviews and revised until optimal. For validation, bilingual patients at seven clinics completed Spanish and English questionnaire versions in randomized order. Participants completed a second set of questionnaires later. The Spanish versions' internal consistency and reliability and Spanish-English agreement were measured using Cronbach's alpha, weighted kappa, and intraclass correlation coefficients. RESULTS: A total of 78 subjects were included; 94.9 % self-identified as Hispanic and 73.1 % spoke Spanish as their primary language. The proportion of per-item missing responses was similar in both languages (median 1.3 %). Internal consistency for Spanish PFDI-20 subscales was acceptable to good and for PFIQ-7 and QUID excellent. Test-retest reliability per item was moderate to near perfect for PFDI-20, substantial to near perfect for PFIQ-7 and 3IQ, and substantial for QUID. Spanish-English agreement for individual items was substantial to near perfect for all questionnaires (kappa range 0.64-0.95) and agreement for PFDI-20, PFIQ-7, and QUID subscales scores was high [intraclass correlation coefficient (ICC) range 0.92-0.99]. CONCLUSIONS: We obtained valid Spanish translations of the PFDI-20, PFIQ-7, QUID, and 3IQ. These results support their use as clinical and research assessment tools in Spanish-speaking populations.

Sensory neuropathy following suspension of the vaginal apex to the proximal uterosacral ligaments.

INTRODUCTION AND HYPOTHESIS: Reports of sensory neuropathy attributed to uterosacral ligament suspension (USLS) have emerged. The objectives of this study were to assess the rate of sensory neuropathy symptoms following transvaginal USLS at a single institution during a 5-year period and to describe the evaluation, management, and outcomes in these patients. METHODS: A retrospective review of records identified 278 women who underwent transvaginal USLS during the study period. Inpatient and outpatient records within the first 4 weeks postsurgery were reviewed. Women with new-onset buttock and/or lower-extremity pain, numbness, weakness or a combination of these symptoms were identified. Demographic data, intraoperative data, and management modalities and outcomes were collected. RESULTS: Nineteen (6.8 %) women met criteria for inclusion. The most common symptom was buttock pain (73.7 % of cases). Pain radiation to the ipsilateral posterior thigh was present in 11 cases (57.9 %). The majority of women (73.7 %) reported pain symptoms on the right side. Conservative treatment modalities were initially implemented in all women. Four women (21 %) underwent suture removal a median of 1.75 months after USLS. Full symptom resolution was reported in 13 (68.4 %) women a median of 6 months after USLS. The remaining women experienced partial symptom resolution with ongoing conservative management. CONCLUSIONS: Sensory neuropathy is common in women who undergo transvaginal USLS. As quality of life may be significantly affected, any symptoms of buttock or lower-extremity pain in the immediate postoperative period warrant a thorough evaluation and close follow-up, with early suture removal consideration.

Anatomic relationships of the pudendal nerve branches.

OBJECTIVE: We sought to characterize the distribution of the pudendal nerve branches and to correlate findings with injury risk related to common midurethral sling procedures. STUDY DESIGN: Dissections were performed in 18 female cadavers. Biopsies were obtained to confirm gross findings by histology. RESULTS: In all dissections, most of the clitoral and perineal nerves coursed caudal to the ventral portion of the perineal membrane. The inferior rectal nerve did not enter the pudendal canal in 44% (n = 8) of specimens. Nerve tissue was confirmed histologically in tissue sampled. CONCLUSION: The clitoral and perineal branches of the pudendal nerve should be at low risk of direct nerve injury during midurethral slings and similar procedures as they course caudal to the ventral portion of the perineal membrane. The inferior rectal nerve might be at risk of injury during procedures that involve passage of needles through the ischioanal fossa.

A Structured, Hybrid Cystoscopy Simulation Curriculum for Obstetrics/Gynecology Residents.

OBJECTIVES: This study aimed to assess the subjective and objective cystoscopy skills of gynecology residents before and after implementation of a comprehensive simulation curriculum. METHODS: Residents in an obstetrics/gynecology program at a single academic institution participated in a 6-week cystoscopy simulation course. Residents attended an initial orientation and didactic presentation, and then weekly 20- to 30-minute training sessions using a water balloon model and a virtual reality simulator. Pretesting and posttesting were performed, including (1) subjective self-assessments, (2) a written quiz, and (3) objective structured assessment of technical skills. Paired t test was used to assess the differences in residents' objective assessment scores before and after simulation training. RESULTS: A total of 16 residents were recruited. Residents reported significant subjective improvements in comfort, confidence, and proficiency in performing cystoscopy after completing the curriculum. Their overall objective assessment improved, including written quiz scores (mean score, 49% vs 78%; P < 0.001), efficiency in cystoscope assembly (means score, 0 vs 4; P < 0.001), overall bladder survey score (56% vs 86%, P < 0.001), and global rating score (mean score, 15 vs 24; P < 0.001). Residents tended to prefer the water-balloon model compared with the virtual reality simulator (75% vs 25%). CONCLUSIONS: Obstetrics/gynecology residents demonstrated significant improvements in subjective and objective measures of skill after completion of a 6-week cystoscopy simulation training course using a combination of low- and high-fidelity models. Although universal cystoscopy at the time of hysterectomy for benign indications remains controversial, cystoscopy simulation should remain an important part of resident training.

Perceptions of Mesh Use for Pelvic Floor Surgery in Latinas: Face Validity of a Spanish Questionnaire.

OBJECTIVE: The aim of the study was to validate a Spanish-translated survey assessing patients' perceptions of mesh use in pelvic floor surgery. METHODS: An English-language survey evaluating perceptions of mesh use underwent a process of Spanish translation and validation, using a forward-backward translation validation protocol. Self-identified bilingual Latinas with symptoms of pelvic floor disorders were recruited to participate in cognitive interviews after completing the survey in English and Spanish. κ coefficient and Cronbach α were calculated for measurement of reliability and internal consistency in responses. A P value of 0.05 was considered statistically significant. RESULTS: A total of 30 women were randomized to complete the initial survey in either English or Spanish. Demographics for the 2 cohorts were similar. For the Spanish-translated survey overall, 86% described the questions as "somewhat easy" or "very easy" to understand, and 93% reported that it was "clear" or "very clear" that the survey aimed to investigate their thoughts regarding mesh use. Approximately 63% of the participants expressed confusion over the use of the Spanish medical term "cabestrillo," translated for "sling." There were no significant differences in the responses on cognitive interview between the 2 groups. Overall, the responses between English and Spanish versions of the survey demonstrated good reliability and internal consistency. CONCLUSIONS: This study demonstrated face validity of a Spanish-translated survey assessing perceptions of mesh use in pelvic surgery in a Latina population. Participants' feedback was crucial to optimizing the quality of the survey for future studies that will evaluate Spanish-speaking patients' views of mesh implants in pelvic reconstructive surgery.

Decision Aid Video for Treatment Selection in Latinas With Symptomatic Pelvic Organ Prolapse: A Randomized Pilot Study.

OBJECTIVES: To assess impact of a decision aid video in Latina patients with symptomatic pelvic organ prolapse (POP) on knowledge, satisfaction and decisional conflict related to initial treatment selection. METHODS: Pilot study with randomized prospective design. Thirty Latina women with symptomatic POP were randomized to a decision aid intervention plus standard care (N = 15) or standard care alone (N = 15) group. Decision aid intervention consisted of a 10-minute video presented at time of initial evaluation for POP. Outcome measures included the Prolapse and Incontinence Knowledge Quiz ("Knowledge"), the Satisfaction with Decision ("Satisfaction") and Decisional Conflict (DCS) scales, and were assessed at 4 different timepoints: after initial visit, and at 1, 3 and 6 months after. Data was analyzed using repeated-measures ANOVA and pairwise between-group comparisons. RESULTS: Demographic and baseline data were similar between groups. There was a significant interaction between groups and time on the Knowledge scores (P = 0.03). Knowledge scores were higher at the initial visit in the intervention group (10.6 ± 0.8 vs 9.53 ± 1.4, P = 0.014). Satisfaction scores were lower in the intervention group on longitudinal analysis, indicating higher satisfaction (P = 0.02). There was no difference on overall Decisional Conflict scores between groups. The intervention group had lower scores on the "effective decision" DCS subscale at 3 and 6 months and "informed" DCS subscale at 3 months. CONCLUSIONS: A decision aid video intervention in Latina women with POP used at the time of initial evaluation may help the patient make a more informed treatment decision by increasing condition-related knowledge and lead to greater long-term satisfaction.

Qualitative Analysis of Knowledge, Attitudes, and Beliefs About Pessary Use Among Spanish-Speaking Women on the US-Mexico Border.

OBJECTIVES: To explore the knowledge, attitudes, and beliefs related to pessary use in Spanish-speaking women along the US-Mexico border. METHODS: Spanish-speaking women with symptoms of vaginal bulge were recruited from the urogynecology/gynecology clinics at Texas Tech University Health Sciences Center El Paso to participate in moderated focus groups. Discussion topics included knowledge of prolapse/pessaries, pros/cons of pessaries, alternatives, and prolapse surgery. Audio-recorded group discussions were transcribed verbatim, and qualitative analysis completed by independent review using grounded theory methodology. Common themes were identified and then aggregated to form consensus concepts, agreed upon by the reviewers. RESULTS: Twenty-nine Spanish-speaking women participated in 6 focus group discussions. Approximately half of women reported little or no prior knowledge about pessaries. Three main themes were identified from analysis: knowledge/perceptions, misinformation/misconceptions, and surgery-related concerns. Concepts identified from common themes included limited knowledge of pessaries, confusing "pessary" with "mesh," willingness to try pessaries in order to avoid surgery, desire to try pessary if it was recommended by physician, limited efficacy or complications of surgery, and mesh-related concerns. Interestingly, some women reported that pessaries appear to be a treatment more often offered in the United States rather than in Mexico. CONCLUSIONS: Most participants showed a willingness to try a pessary for symptoms of pelvic organ prolapse in an effort to avoid surgery, despite expressing limited knowledge about this treatment. Physician recommendations and risks of pessary use influence their likelihood of trying a pessary. These concepts serve as focus points for effective pessary counseling to help improve education and informed decision making in this patient population.

Staged repair of concomitant rectovaginal fistula and pelvic organ prolapse after removal of a neglected pessary.

Rectovaginal fistulas are a rare complication of neglected pessaries and can pose challenges in managing pelvic organ prolapse. We describe a 66-year-old woman with uterine procidentia who presented with a neglected Gellhorn pessary in place for 5 years. She complained of constipation and persistent vaginal bulge. On examination, the pessary stem eroded through the mid-posterior vaginal wall and anterior rectal wall. Staged surgical treatment included (1) pessary removal and development of ileostomy, (2) rectovaginal fistula repair, and (3) vaginal hysterectomy, uterosacral ligament suspension, and ileostomy reversal. Short-term follow-up did not demonstrate evidence of fistula or recurrence of prolapse. Rectovaginal fistulae resulting from neglected pessaries pose challenges in managing concomitant vaginal prolapse. A staged approach to fistula and prolapse repair is possible with the potential for good outcomes.

Posterior Vaginal Compartment Anatomy: Implications for Surgical Repair.

OBJECTIVES: To examine the gross and histologic anatomy of the proximal, mid, and distal posterior vaginal compartment and discuss implications for surgical repair. STUDY DESIGN: In this cadaver study, pelvic organs were resected en bloc, immersed in formalin solution, and transected in the mid sagittal plane. Measured distances included: posterior vaginal wall length, cervicovaginal junction or vaginal cuff to posterior peritoneal reflection, peritoneal reflection to proximal edge (apex) of perineal body, and perineal body apex to hymenal remnant (height). The posterior vaginal wall was divided into 3 segments along the midsagittal plane and submitted in whole tissue blocks for staining. Histologic analysis included that of 2 young nulliparous women whose tissue was harvested within 12 hours of death. RESULTS: Eleven cadavers were examined. Median (interquartile range [IQR]) posterior vaginal length was 7.6 (2.2) cm. The peritoneum attached to the posterior vaginal wall a median (IQR) of 1.3 cm (0.5 cm) distal to the cervicovaginal junction (n = 8). The rectovaginal space, spanning from the peritoneal reflection to perineal body apex, had a median (IQR) length of 4.7 cm (2.1 cm). Microscopic examination of the mid segment revealed a layer of loose fibroadipose tissue between the vaginal/rectal walls, with no distinct dense fibroconnective tissue layer. The median (IQR) perineal body height was 2.3 cm (1.2 cm). No discrete fibrous capsule was seen surrounding the external anal sphincter muscle. CONCLUSIONS: These findings support evidence showing absence of a rectovaginal fascia. The anal sphincter lacks a fibrous capsule, which is important during closure of third-/fourth-degree obstetric lacerations.
