Educating Women About Pelvic Floor Disorders During Pregnancy From the First to the "Fourth Trimester": A Randomized Clinical Trial.

IMPORTANCE: Pregnancy and childbirth are risk factors for developing pelvic floor disorders (PFDs), and this continues postpartum ("fourth trimester"). Knowledge of PFDs among women of childbearing age is lacking and presents an opportunity for education. OBJECTIVES: The aim of this study was to compare the increase in knowledge of PFDs in patients who received written handouts versus interactive workshops as measured by the Prolapse and Incontinence Knowledge Questionnaire (PIKQ). STUDY DESIGN: This was a randomized clinical trial of pregnant patients 18 years or older. Patients either received written handouts only or received handouts and attended an interactive workshop. Handouts were created in collaboration with communication specialists focusing on risk factors and prevention strategies. The primary outcome was the change in PIKQ score. Secondary outcomes were Pelvic Floor Distress Inventory score and postpartum phone interviews of workshop group participants. Questionnaires were assessed at recruitment and 6 weeks postpartum. The nonparametric Wilcoxon test compared continuous variables, and the Fisher exact test compared categorical variables. RESULTS: One hundred twenty patients were randomized. Demographics were similar between groups. Median PIKQ score change showed no difference between groups (P = 0.37). Pelvic Floor Distress Inventory-20 scores were similar between groups at baseline (P = 0.78) and postpartum (P = 0.82). Quantile regression showed posteducation PIKQ scores were significantly higher in the workshop (21.00 vs 17.00; P = 0.011) and written (21.00 vs 17.00; P < 0.001) groups. Phone interviews showed consistent themes: (1) greater awareness of PFDs, (2) more likely to discuss PFDs, and (3) relief that PFDs are treatable. Fifty-nine percent of patients preferred learning through workshops compared with the handouts. CONCLUSIONS: Both groups showed improvement in knowledge of PFDs. Well-written, illustrated handouts were effective in increasing patient knowledge of PFDs.

An evaluation of pelvic floor disorders in a public and private healthcare setting.

INTRODUCTION AND HYPOTHESIS: The objectives were to determine whether a difference exists in the duration of pelvic floor disorder (PFD) symptoms among patients presenting to urogynecologists in two healthcare systems: private and county; and to elucidate differences in baseline characteristics, type of PFDs, symptom severity and management, stratified by healthcare plans. METHODS: A multi-center retrospective study was conducted including new patients presenting to three urogynecology clinics between March 2016 and May 2018: one private clinic (site A) and two public clinics in the same county healthcare system (sites B and C). Baseline data included age, race, BMI, parity, and comorbidities. Primary outcome was "time to presentation" defined as PFD duration in months. Secondary outcomes were symptom severity and PFD management, analyzed by healthcare setting and insurance type. RESULTS: A total of 1,055 private and 439 public patients were included. Patients in the public setting were younger (54 vs 61 years, p<0.001), largely Hispanic (76% vs 14%, p<0.001), of higher parity (4 vs 3, p=0.001), and had more comorbidities, with a predominance of county-funded healthcare plans. There was no difference in duration of symptoms between the public and private groups respectively (54 vs 56 months, p=0.94). Patients in the public setting had more severe urinary incontinence (3 vs 2 pads/day, p<0.001) and prolapse (stages 3-4, 71% vs 61%, p=0.004); however, they had lower rates of surgical management for stress incontinence and prolapse. Differences in fecal incontinence could not be evaluated owing to small sample size. CONCLUSIONS: Public patients presented younger with more severe symptoms but had lower rates of surgery for PFDs traditionally managed surgically.

Health Care Disparities in Surgical Management of Pelvic Organ Prolapse: A Contemporary Nationwide Analysis.

OBJECTIVES: Our objective was to compare the rate of native tissue repair (NTR) versus sacrocolpopexy (SCP) and reconstructive (RECON) versus obliterative repair (OBR) for the treatment of pelvic organ prolapse (POP), evaluating for health care disparities based on race, socioeconomic, and geographic factors. METHODS: The National Inpatient Sample database was queried for patients older than 18 years undergoing POP surgery from 2008 to 2018. Baseline demographics, comorbidity index, socioeconomic, and hospital variables were extracted. The weighted t test, Wilcoxon test, and χ2 test were used to compare the rate of (1) NTR versus SCP and (2) RECON vs OBR. Multivariate weighted logistic regression was used to compare while controlling for confounders. Reference groups were White race, Medicare patients, northeast region, small hospital size, and rural location. RESULTS: Of 71,262 patients, 67,382 (94.6%) underwent RECON. Patients undergoing OBR were older and had a higher comorbidity score. Multivariate analysis showed the following: (1) Black, Hispanic, and other races; (2) Medicaid patients; (3) patients at urban teaching hospitals are less likely to receive RECON. Patients in the midwest were more likely to receive RECON. Among 68,401 patients, 23,808 (34.8%), and 44,593 (65.19%) underwent SCP and NTR, respectively. Hysterectomy was more common in the NTR group. Multivariate analysis showed the following:(1) Black, Hispanic, and "other" races; (2) uninsured and Medicaid patients; (3) patients in the midwest, south, and west were at higher odds of receiving NTR. Patients in large and urban hospitals were less likely to undergo NTR. CONCLUSIONS: Racial, socioeconomic, and geographic disparities exist in surgical management for POP warranting further study to seek to eliminate these disparities.

Barriers to Care Affecting Presentation to Urogynecologists in a Community Setting.

OBJECTIVE: To evaluate barriers to care for patients presenting to urogynecologists and determine how these barriers differ in private and public/county health care settings. METHODS: Standardized anonymous questionnaires were distributed from May 2018 to July 2018 to new patients presenting to a urogynecologist at three institutions: two private health care clinics (sites A and B) and one public/county hospital clinic (site C). Patients identified symptom duration, symptom severity, and factors inhibiting presentation to care from a list of barriers. Patients then identified the primary barrier to care. RESULTS: One hundred nine questionnaires were distributed, and 88 were submitted, resulting in an 81% response rate (31 from site A, 30 from site B, 27 from site C). In analysis of the private versus public setting, there was no statistical difference between age (58 years vs 57 years, P = 0.69), body mass index (28 vs 30, P = 0.301), symptom duration (24 months vs 16 months, P = 0.28), or severity respectively. When asked to identify the primary barrier to presentation, patients in the private setting stated they did not know to see a specialist (26.2%, P = 0.002), while patients in the public setting could not obtain a closer appointment time (22.2% vs 13.1%, P = 0.35. Additionally, patients in the public setting were more likely to cite lack of health care coverage as a barrier to care (18.5% vs 1.6%, P = 0.01). CONCLUSION: This study highlights barriers that can contribute to the disparity of care seen in our patient population. Efforts should be made to acknowledge and mitigate hindrances impacting access to care.

Vaginal intraperitoneal versus extraperitoneal uterosacral ligament vault suspensions: a comparison of a standard and novel approach.

INTRODUCTION AND HYPOTHESIS: Uterosacral ligament suspension surgery is commonly utilized to correct post-hysterectomy vaginal vault prolapse (VVP). Vaginal intraperitoneal uterosacral vault suspension (IUSVS) is a viable option, but intraperitoneal access can be challenging. An alternative approach is an extraperitoneal uterosacral vault suspension (EUSVS). The aim of our study was to compare surgical outcomes of IUSVS and EUSVS in patients with post-hysterectomy VVP. METHODS: Retrospective cohort study of women who underwent treatment of post-hysterectomy VVP with an IUSVS and EUSVS from May 2016 to January 2019 at our institution. The primary outcome was surgical success that was assessed by a composite outcome for surgical failure, defined as ANY of the following: (1) apical descent > 1/3 of the TVL or anterior or posterior vaginal wall beyond the hymen, (2) retreatment of prolapse, or (3) bothersome vaginal bulge symptoms with a positive response to either of two questions on the PFDI questionnaire. Secondary outcomes included EBL, operative time, duration of hospitalization, and perioperative complications. Two-sample t-tests and chi-square tests were used for the bivariate analysis. RESULTS: Eighty patients were included (36 IUSVS and 44 EUSVS) with a mean follow-up of 7 months. For our primary outcome, there was no difference in surgical success (IUSVS group 72.22% vs. EUSVS group 81.82%, p = 0.307). Operative time, duration of hospitalization, and EBL were significantly less in the EUSVS group than in the IUSVS group. CONCLUSIONS: EUSVS demonstrated similar short-term success compared to IUSVS for post-hysterectomy VVP, with shorter operative time, EBL, and length of stay.

Overactive Bladder Symptoms After Pelvic Organ Prolapse Repair.

OBJECTIVES: This study aimed to identify the characteristics associated with overactive bladder (OAB) symptoms perioperatively in patients undergoing pelvic organ prolapse (POP) surgery with and without slings and to determine the rate of OAB symptom resolution postoperatively. METHODS: This retrospective, single-institution study involved women undergoing prolapse surgery with and without concomitant midurethral sling from 2011 to 2016. A validated questionnaire was used to determine OAB symptoms preoperatively and postoperatively. The primary outcome was rate of resolution in OAB symptoms after POP surgery with and without midurethral sling. Baseline characteristics and surgery type were presented, and univariate and multivariate logistic regression models were applied to evaluate characteristics associated with OAB symptoms at the first postoperative visit. RESULTS: The analysis included 203 patients. Among those with baseline OAB symptoms, 103 (61%) had symptom resolution, whereas 66 (39.1%) reported persistent symptoms. Among 34 patients without baseline OAB symptoms, 6% developed de novo symptoms. Older age was found to be a significant risk factor for persistence of symptoms postoperatively both on univariate (odds ratio, 0.97; 95% confidence interval, 0.94-1; P = 0.038) and multivariate logistic regression (odds ratio, 0.96, 95% confidence interval, 0.92-1; P = 0.049). The rate of medication discontinuation postoperatively was 25%. CONCLUSIONS: Approximately 61% of patients undergoing POP surgery had resolution of OAB symptoms postoperatively whether or not an incontinence procedure was performed. Older age was significantly related to persistent OAB symptoms in both univariate (P = 0.038) and multivariate (P = 0.049) models. The rate of de novo OAB symptoms was 6%.

A 12-Month Clinical Durability of Effectiveness and Safety Evaluation of a Vaginal Bowel Control System for the Nonsurgical Treatment of Fecal Incontinence.

OBJECTIVE: The aim of this study was to characterize clinical success, impact on quality of life, and durability up to 1 year in women with fecal incontinence (FI) responsive to an initial test period with a trial vaginal bowel control system. METHODS: This was a prospective open-label study in subjects with FI and successfully fit who underwent an initial 2-week trial period. Those achieving 50% or greater reduction in FI episodes were provided the long-term system. Primary outcome was success at 3 months defined as 50% or greater reduction in baseline FI episodes, also assessed at 6 and 12 months. Secondary outcomes included symptom impact measured with Fecal Incontinence Quality of Life scale, symptom severity by the St Mark's (Vaizey) questionnaire, Patient Global Impression of Improvement, and satisfaction. Adverse events were collected. Primary analysis was intention to treat (ITT). RESULTS: Seventy-three subjects with baseline mean of 14.1 ± 12.15 FI episodes over 2 weeks entered the treatment period. Success rate at 3 months was 72.6% (53/73, P < 0.0001); per-protocol, 84.1% (53/63, P < 0.0001). Significant improvement in all Fecal Incontinence Quality of Life subscales and St Mark's questionnaire meeting minimally important differences was noted. Satisfaction was 91.7%, 89.7%, and 94.4% at 3, 6, and 12 months, respectively; 77.4%, 77.6%, and 79.6% were very much/much better on the Patient Global Impression of Improvement at 3, 6, and 12 months, respectively. Most common adverse event was vaginal wall injury, with most adverse events (90/134, 67%) occurring during fitting period. CONCLUSIONS: In women with successful fitting and initial treatment response, durable efficacy was seen at 3, 6, and 12 months by objective and subjective measures, with favorable safety.

Characteristics Associated With Successful Fitting of a Vaginal Bowel Control System for Fecal Incontinence.

OBJECTIVES: We previously showed that management with a novel vaginal bowel control system was efficacious in women with moderate to severe fecal incontinence. The objective of this secondary analysis was to evaluate the clinical characteristics associated with device-fitting success. METHODS: This is a secondary analysis of an institutional review board-approved, multicenter, prospective, open-label clinical study of women aged 19 to 75 years with 4 or more episodes of fecal incontinence recorded on a 2-week baseline bowel diary. Those successfully fitted with the vaginal bowel control device entered a 1-month treatment period, and efficacy was assessed with a repeat bowel diary. Demographic data, medical and surgical history, and pelvic examination findings were compared across women with successful and unsuccessful completion of the fitting period. Multivariate logistic regression analysis was performed. RESULTS: Six clinical sites in the United States recruited from August 2012 through October 2013. Overall, 110 women underwent attempted fitting, of which 61 (55.5%) of 110 were successful and entered the treatment portion of the study. Multivariate logistic regression analysis revealed that previous prolapse surgery (P = 0.007) and shorter vaginal length (P = 0.041) were independently associated with unsuccessful fitting. Women who have not undergone previous prolapse surgery had 4.7 times the odds (95% confidence interval [CI], 1.53-14.53) of a successful fit. In addition, for every additional centimeter of vaginal length, women had 1.49 times the odds (95% CI, 1.02-2.17) of a successful fit. CONCLUSIONS: Shorter vaginal length and previous prolapse surgery were associated with an increased risk of fitting failure. These findings may be used to inform patients regarding their expectation of successful fitting.

Impact of a Novel Vaginal Bowel Control System on Bowel Function.

BACKGROUND: Bowel dysfunction, including frequency, fecal urgency, stool consistency, and evacuation symptoms, contributes to fecal incontinence. OBJECTIVE: The purpose of this study was to examine the impact of a vaginal bowel control system on parameters of bowel function, including frequency, urgency, stool consistency, and evacuation. DESIGN: This was a secondary analysis of a multicenter, prospective clinical trial. SETTINGS: This study was conducted at 6 sites in the United States, including university hospitals and private practices in urogynecology and colorectal surgery. PATIENTS: A total of 56 evaluable female subjects aged 19 to 75 years with 4 or more fecal incontinence episodes on a 2-week bowel diary were included. INTERVENTIONS: The study intervention was composed of the vaginal bowel control system, consisting of a vaginal insert and pressure-regulated pump. MAIN OUTCOME MEASURES: Subjects completed a 2-week baseline diary of bowel function before and after treatment completed at 1 month. Fecal urgency, consistency of stool (Bristol score), and completeness of evacuation were recorded for all bowel movements. RESULTS: Use of the insert was associated with an improvement in bowel function across all 4 categories. Two thirds (8/12) of subjects with a high frequency of daily stools (more than 2 per day) shifted to a normal or low frequency of stools. Analysis of Bristol stool scale scores demonstrated a significant reduction in the proportion of all bowel movements reported as liquid (Bristol 6 or 7), from 36% to 21% (p = 0.0001). On average, 54% of stools were associated with urgency at baseline compared with 26% at 1 month (p < 0.0001). Incomplete evacuations with all bowel movements were reduced from 39% to 26% of subjects at 1 month (p = 0.0034). LIMITATIONS: The study follow-up period was 1 month (with an optional additional 2 months). CONCLUSIONS: The vaginal bowel control system was associated with an improvement in bowel symptoms and function, including reduced bowel movement frequency, less fecal urgency, increased solid consistency, and improved evacuation in patients with significant fecal incontinence.

A vaginal bowel-control system for the treatment of fecal incontinence.

OBJECTIVE: To evaluate the effectiveness and safety of a vaginal bowel-control device and pump system for fecal incontinence treatment. METHODS: Women with a minimum of four fecal incontinence episodes over 2 weeks were fit with the intravaginal device. Treatment success, defined as a 50% or greater reduction of incontinent episodes, was assessed at 1 month. Participants were invited into an optional extended-wear period of another 2 months. Secondary outcomes included symptom improvement measured by the Fecal Incontinence Quality of Life, Modified Manchester Health Questionnaire, and Patient Global Impression of Improvement. Adverse events were collected. Intention-to-treat analysis included participants who were successfully fit entering treatment. Per protocol, analysis included participants with a valid 1-month treatment diary. RESULTS: Sixty-one of 110 (55.5%) participants from six clinical sites were successfully fit and entered treatment. At 1 month, intention-to-treat success was 78.7% (48/61, P<.001); per protocol success, 85.7% (48/56, P<.001) and 85.7% (48/56) considered bowel symptoms "very much better" or "much better." There was significant improvement in all Fecal Incontinence Quality of Life (P<.001) and Modified Manchester (P≤.007) subscales. Success rate at 3 months was 86.4% (38/44; 95% confidence interval 73-95%). There were no serious adverse events; the most common study-wide device-related adverse event was pelvic cramping or discomfort (25/110 participants [22.7%]), the majority of events (16/25 [64%]) occurring during the fitting period. CONCLUSION: In women successfully fit with a vaginal bowel-control device for nonsurgical treatment for fecal incontinence, there was significant improvement in fecal incontinence by objective and subjective measures.

Laparoscopic cervicoisthmic cerclage: technique and systematic review of the literature.

BACKGROUND AND AIMS: To report on and review the outcome after laparoscopic cervicoisthmic cerclage (LCC) and robotic-assisted laparoscopic cervicoisthmic cerclage. METHODS: We reported on 4 cases of LCC and conducted a systematic review of the literature up to May 2012 to identify obstetric outcomes after LCC and robotic-assisted LCC. RESULTS: The median age of our series was 35 years (range: 31-41) with median previous pregnancies 3.5 (2-5). All 4 women had successful obstetric outcomes with a median gestational age at delivery of 37 weeks (range: 36-38). The systematic review identified 25 studies (162 women underwent LCC and 3 had robotic-assisted LCC). In the interval LLC studies, the median age was 33 years (range: 22-42); with a median gestational age at delivery of 37 weeks (range: 34-38). For prophylactic LCC, the median age was 31 years (range: 27-41); with a gestational age at delivery of 37 weeks (range: 19-39). Two of the three robotic-assisted LCC procedures were done prophylactically. The median age was 27 years (range: 23-37) with a median gestational age at delivery of 37 weeks (range: 35-38). CONCLUSION: LCC is feasible during and in between pregnancies as well as in congenitally malformed uteri. Current evidence suggests that LCC might be of benefit in selected cases of cervical insufficiency with short cervices.

Does body mass index impact passing voiding trial after midurethral sling procedures for stress urinary incontinence?

OBJECTIVE: : To test the hypothesis that body mass index (BMI) is a factor associated with passing a voiding trial after midurethral sling procedures for stress urinary incontinence (SUI). STUDY DESIGN: : The medical records of 136 consecutive patients who underwent placement of either tension-free vaginal tape (TVT) or transobturator tape (TOT) for SUI during a 1-year period (September 1, 2007 to August 31, 2008) were retrospectively reviewed. Variables assessed were BMI, age, and passing or failing a postoperative urinary voiding trial. Patients with concomitant pelvic organ prolapse surgeries were not included in this analysis. RESULTS: : Sixty-seven patients underwent TVT, whereas 69 had TOT procedures. In the TVT group, 30 patients (42%) were unable to void immediately postoperatively compared with 11 patients (16%) in the TOT group (P = 0.0003). The mean (SD) age and BMI of patients who failed or passed voiding trials was 58.6 (12.0) years and 28.0 (4.9) kg/m or 53.5 (12.3) years and 29.8 (5.7) kg/m, respectively. Of 38 patients who did not pass a voiding trial on the day of the procedure, 31 (82%) passed on postoperative day 1, and all patients had passed a voiding trial by postoperative day 11. The mean (SD) BMI for 7 patients who did not pass voiding trial by postoperative day 1 was 28.3 (5.2) kg/m. CONCLUSIONS: : Women with higher BMIs were more likely to pass voiding trials after midurethral sling procedures. Patients who had TOT placement had greater success passing a postprocedure voiding trial than did patients who had TVT placement.

Hemorrhagic complication during placement of tension-free vaginal tape.

A 66-year-old para III with a 20-year history of stress urinary incontinence underwent placement of tension-free vaginal tape. Intraoperative arterial bleeding occurred. An expanding hematoma was palpated postoperatively. Interventional radiology performed a pelvic arteriogram with selective bilateral internal iliac arteriograms, a supraselective anterior division and obturator arteriogram, a left external iliac arteriogram, coil embolization of a branch of the left obturator artery, and gel foam embolization of the anterior division of the left internal iliac artery.

Effect of estrogen replacement on the histologic response to polypropylene mesh implanted in the rabbit vagina model.

OBJECTIVE: The aim of this study was to determine the effect of estrogen replacement after ovariectomy on the histologic response to polypropylene mesh implanted in rabbit vagina. STUDY DESIGN: Thirty rabbits were assigned to 5 groups: sham laparotomy, ovariectomy, ovariectomy-preoperative estrogen, ovariectomy-postoperative estrogen, or ovariectomy-preoperative and postoperative estrogen. Rabbits underwent sham surgery or ovariectomy and were infused with vehicle or 17beta-estradiol (200 microg/d) for 4 weeks ("preoperative" estrogen). Polypropylene mesh was implanted in the posterior vaginal wall, and rabbits were infused with vehicle or "postoperative" estrogen for an additional 8 weeks. Grafts were harvested and underwent histologic evaluation. RESULTS: Vaginal atrophy in ovariectomized rabbits was reversed by estrogen replacement. Scores for inflammation (P = .33) and neovascularization (P = .23) at the graft site were not different among estrogen replacement groups, but estrogen administration was associated with increased collagen deposition (P = .005). CONCLUSION: Estrogen replacement administered for 8 weeks postoperatively increases collagen deposition into polypropylene mesh.

Does mental imagery prior to cystoscopy make a difference? A randomized controlled trial.

OBJECTIVE: We sought to determine whether mental imagery improves surgical performance of residents novice to cystoscopy. STUDY DESIGN: We performed a multicenter randomized controlled trial. Residents who had performed < or = 3 cystoscopies were randomized to preoperative mental imagery sessions or reading a book chapter describing cystoscopy. The primary outcome was comparison of groups' surgical performance scores. Secondary outcomes were measurements of operative times and resident ratings of helpfulness of their preparation. Scores were compared using 2-factor analysis of variance. RESULTS: In all, 68 residents were randomized; 33 to imagery and 35 to control groups. Groups did not differ in age, cystoscopic experience, residency level, or sex. The imagery group's surgical assessment scores were 15.9% higher than controls (P = .03). Operative times did not differ between groups. Imagery residents rated imagery preparation as more helpful than controls (P < .0001). CONCLUSION: Residents considered mental imagery to be a more useful preoperative preparation. The mental imagery group's surgical performance was superior to controls.

Biomechanical properties of synthetic and biologic graft materials following long-term implantation in the rabbit abdomen and vagina.

OBJECTIVE: We sought to evaluate the effects of anatomic location and ovariectomy on biomechanical properties of synthetic and biologic graft materials after long-term implantation. STUDY DESIGN: A total of 35 rabbits underwent ovariectomy or sham laparotomy and were implanted with polypropylene (PP) mesh (n = 17) or cross-linked porcine dermis (PS) (n = 18) in the vagina and abdomen. Grafts were harvested 9 months later and underwent mechanical properties testing. RESULTS: After implantation, PS was similar in strength (P = .52) but was twice as stiff as PP (P = .04) and had a maximal elongation only half that of PP (P < .001). Degradation of PS was associated with decreased ultimate tensile strength (P = .03) and elastic modulus (P = .046). Vaginal PP grafts shrunk more (P < .001) and were less stiff than abdominal PP grafts (P = .049) but were not different in strength (P = .19). Ovariectomy had no effect (P > .05). CONCLUSION: Cross-linked PS undergoes long-term degradation resulting in compromised biomechanical properties and thus is likely inferior to lightweight PP meshes for pelvic organ prolapse and incontinence procedures.

Long-term histologic response to synthetic and biologic graft materials implanted in the vagina and abdomen of a rabbit model.

OBJECTIVE: We sought to evaluate the effects of graft type, site of implantation, and ovariectomy on the long-term histologic response to graft materials used in pelvic reconstructive surgery. STUDY DESIGN: In all, 45 rabbits underwent ovariectomy or sham laparotomy and were implanted with polypropylene (PP) mesh (n = 23) or cross-linked porcine dermis (PS) (n = 22) in the vagina and abdomen. Grafts were harvested 9 months later and were processed for histology to evaluate the host inflammatory response and degree of tissue incorporation within the grafts. RESULTS: Polypropylene induced a milder (P < .007), more uniform response than PS, whereas PS elicited a more variable response and degraded by 9 months. Vaginal grafts had higher scores for inflammation (P = .005) and neovascularization (P < .001), and had lower scores for fibroblastic proliferation (P < .001) than abdominal grafts. Ovariectomy had no effect (P > .05). CONCLUSION: Synthetic and biologic grafts evoke different foreign body responses, which may have implications for surgical outcomes in women.

Transverse cystocele repair with uterine preservation using native tissue.

The goals of this study were to describe the surgical procedure of the transverse cystocele repair with uterine preservation using native tissue and to examine the surgical complications and short-term anatomical outcomes of this operation. Patients who underwent transverse cystocele repair with uterine preservation at our institution were identified by retrospective chart review for the interval from January 2001 to September 2006. Sixty-nine patients were identified. Median point for first postoperative visit was 6.1 weeks (range 3-101 weeks). Average age was 66.6 +/- 13.1 years (range 33-89). Patients undergoing this procedure had no intraoperative complications and high frequency of initial anatomic success (defined as Baden-Walker halfway system grade 0 or 1 for anterior compartment) during a relatively short follow-up interval. Preoperatively, bladder grade averaged 2.6 with postoperative grade averaging 0.02. Based on our initial anatomical findings, we conclude that this surgical approach has merit for a subset of patients with adequate uterine support.

Histologic response of porcine collagen-coated and uncoated polypropylene grafts in a rabbit vagina model.

OBJECTIVE: The purpose of this study was to determine whether the host tissue response in the rabbit vagina differs for 2 synthetic graft materials that are used in pelvic reconstructive surgery. STUDY DESIGN: One strip of porcine collagen-coated or uncoated polypropylene mesh was implanted adjacent to a sham operative site into the posterior vagina of 10 New Zealand white rabbits and harvested 12 weeks later. Rabbits were assigned randomly to group 1 (coated; n = 5), group 2 (uncoated; n = 5), or group 3 (unoperated; n = 4). Full-thickness sagittal sections of posterior vaginal wall and rectum were scored for inflammation, neovascularization, and fibroblastic proliferation. RESULTS: Erosion of grafts did not occur in any animal. Coated and uncoated meshes induced a mild inflammatory response with minimal fibrosis and good host tissue incorporation within the grafts. Few apoptotic and proliferating cells were seen for both graft types. CONCLUSION: Both coated and uncoated polypropylene meshes elicit a mild foreign body reaction and minimal fibrotic response without evidence of vaginal epithelial erosion.
