Case log trends of urogynecology and reconstructive pelvic surgery fellows: A comparison of urology- and gynecology-based fellowship programs.

AIMS: Urogynecology and Reconstructive Pelvic Surgery (URPS) fellowship can be pursued after completion of either a urology (URO) or obstetrics and gynecology (GYN) residency. Our aim is to determine differences in graduating fellow cohort (GFC) case logs between URO- and GYN-based URPS programs. METHODS: Accreditation Council for Graduate Medical Education case logs for URPS GFCs in both GYN- and URO-based programs were analyzed for the 2019-2023 academic years (AY). Unpaired t-tests with Welch's correction were used to compare annual mean logged cases between URO- versus GYN-based GFCs for select surgical categories and the top 11 most logged index cases. RESULTS: GYN-based GFCs logged more cases for all pelvic organ prolapse (POP) categories including surgery on apical POP, anterior wall POP, and posterior wall POP (all p < 0.01), while URO-based GFCs logged more cases for surgery on the urinary system (p = 0.03). For the top 11 logged procedures, URO-based GFCs logged more sacral neuromodulation cases (p = 0.02), whereas GYN-based GFCs logged more slings, vaginal hysterectomies, minimally-invasive hysterectomies, vaginal apical POP, vaginal posterior POP, vaginal anterior POP, and minimally-invasive apical POP cases (all p < 0.01). There was no difference between URO- and GYN-based GFCs for complex urodynamics, cystoscopy with botox injection, or periurethral injection cases. CONCLUSIONS: URO-based URPS fellows tend to graduate with more surgery on the urinary system and sacral neuromodulation cases, while GYN-based fellows perform more slings, hysterectomies, and POP surgery. These findings may help fellowships better understand potential differences in training among graduates from URO- and GYN-based programs and encourage collaboration to lessen these discrepancies.

Postoperative Activity Restrictions After Slings: A Randomized Controlled Trial.

IMPORTANCE: Restricting activity after midurethral slings is an unproven practice. OBJECTIVE: The objective of this study was to evaluate the effect of postoperative activity restriction on satisfaction and outcomes after slings. STUDY DESIGN: This was a multicenter, 2-arm, noninferiority randomized controlled trial. Patients aged 18-85 years undergoing treatment with a midurethral sling were randomized 1:1 to postoperative activity restriction or liberal activity. Restrictions included avoidance of strenuous exercise and heavy lifting. The liberal group was allowed to resume activity at their discretion. Our primary outcome was satisfaction with postoperative instruction at 2 weeks. Secondary outcomes included surgical failure, mesh exposure rates, and other adverse events. RESULTS: In total, 158 patients were randomized with 80 to the liberal group and 78 to the restricted group. At 2 weeks, 54 (80.6%) of patients in the liberal group and 48 (73.9%) of patients in the restricted group were satisfied. We found statistical evidence supporting the hypothesis that postoperative liberal activity instruction is noninferior to activity restriction with regard to patient satisfaction (P = 0.0281). There was no significant difference in strenuous activity at 2 weeks (P = 0.0824). The liberal group reported significantly more moderate activity at 2 weeks (P = 0.0384) and more strenuous activity at 6 weeks and 6 months (P = 0.0171, P = 0.0118, respectively). The rate of recurrent or persistent stress incontinence for liberal versus restricted groups was 18.52% versus 23.53% (P = 0.635). There were no statistically significant differences in complication rates. CONCLUSIONS: Postoperative liberal activity was noninferior to activity restriction with regard to patients' satisfaction. There was no evidence supporting a statistically significant association between postoperative instruction and negative surgical outcomes.

ChatGPT in Urogynecology Research: Novel or Not?

IMPORTANCE: ChatGPT (Chat Generative Pre-trained Transformer) is an artificial intelligence (AI) chatbot that provides human-like responses to text prompts. Little is known regarding ChatGPT's ability to identify original research ideas in urogynecology. OBJECTIVE: Our objective was to evaluate the accuracy of ChatGPT in generating novel systematic review (SR) and research ideas in urogynecology. STUDY DESIGN: In this cross-sectional study, we asked ChatGPT to generate 10 novel SR ideas that have not yet been published for each of the following 5 topics: (1) urogynecology, (2) tension-free vaginal tape slings, (3) pessaries for pelvic organ prolapse, (4) beta-3 agonist use for overactive bladder, and (5) sexual function with genitourinary syndrome of menopause. Research idea novelty was assessed by cross-referencing PubMed and Scopus to determine if any prior publications existed. RESULTS: ChatGPT proposed 50 total SR ideas, including 10 for each prompt. Overall, ChatGPT showed 54% overall accuracy in developing novel SR ideas. Nonnovel SR ideas had a median of 19 (interquartile range, 8-35) published SRs on the suggested topic. When stratified by prompt type, 50% of general and 40-70% of specific urogynecology proposed SR ideas were found to be novel. There were no publications of any type identified for 7 of the 50 suggested ideas. CONCLUSIONS: ChatGPT may be helpful for identifying novel research ideas in urogynecology, but its accuracy is limited. It is essential for those using ChatGPT to review existing literature to ensure originality and credibility. As AI transforms health care, we encourage all urogynecologists to familiarize themselves with popular AI platforms.

Vaginal Estrogen Prescribing and Cost Trends Among Medicare Part D Beneficiaries.

IMPORTANCE: In 2016, the American College of Obstetricians and Gynecologists issued a Committee Opinion on the safety of vaginal estrogen (VE) in estrogen-dependent breast cancer patients. Since that time, prescribing trends of VE have not been studied. OBJECTIVE: Our objective was to analyze expenditure and prescribing trends of VE from 2016 to 2020 for Medicare Part D beneficiaries. STUDY DESIGN: In this retrospective review, we queried the Medicare Part D Spending and Prescriber Datasets from 2016 to 2020 to identify claims for VE. Trends regarding claims, expenditures, beneficiaries, and prescribers were examined. A subanalysis of the Medicare Part D Prescriber Dataset was performed for obstetrician-gynecologist-specific trends. Statistical analysis was done with the Kruskal-Wallis test. RESULTS: From 2016 to 2020 for all specialties, the number of VE claims decreased annually from 945,331 in 2016 to 320,571 in 2020. Most claims were for Estrace (49.5%) followed by Yuvafem (23.3%), Vagifem (14.5%), and Estring (12.7%). The number of VE prescribers decreased from 20,216 to 5,380, with obstetrician-gynecologists comprising 60% of all prescribers. Beneficiaries decreased by more than 70% from 439,210 to 123,318, whereas average spending per beneficiary increased from $688.52 to $1,027.55. Total annual spending on VE decreased from $277,891,645 to $106,679,580. However, average spending per claim increased from $293.40 to $355.28 and increased for all products besides Yuvafem. CONCLUSIONS: Vaginal estrogen claims, beneficiaries, and total expenditures across all provider types have decreased from 2016 to 2020. However, spending per beneficiary and VE claims have increased. Our data suggest that utilization and accessibility of vaginal estrogen may be influenced, in part, by cost.

Third-Line Overactive Bladder Therapies on TikTok: What Does the Public Learn?

IMPORTANCE: Millions of people rely on social media platforms, including TikTok, for health-related information. TikTok has not yet been evaluated as an information source for overactive bladder (OAB) third-line therapies. OBJECTIVES: Our aim was to assess TikTok videos on third-line therapies for OAB for misinformation and quality. STUDY DESIGN: In this cross-sectional analysis, we abstracted the top 50 TikTok videos for keywords: "Axonics," "sacral neuromodulation," "Interstim," "PTNS," "posterior tibial nerve stimulation," and "bladder Botox." Videos were scored for quality by 3 independent reviewers using the Medical Quality Video Evaluation Tool (MQ-VET). Two reviewers determined if videos contained misinformation. RESULTS: Of 300 videos screened, 119 videos were included. Twenty-four (21%) were created by medical professionals (MPs). Medical professional videos were more frequently shared (5 vs 1, P < 0.01) but had similar views, likes, comments, and length. Although MP videos had significantly higher MQ-VET scores (43 vs 27, P < 0.01), there was no difference in the rate of misinformation between MP and non-MP videos (21% vs 18%). Twenty-two videos (18.4%) contained misinformation, which were 3 times longer (50.5 vs 15 seconds, P < 0.01) and had higher MQ-VET scores (34.5 vs 27, P = 0.03) than those without misinformation. Common themes of misinformation pertained to therapy indication, mechanism of action, and patient limitations after undergoing therapy. CONCLUSIONS: Many TikTok videos on OAB third-line therapies contain misinformation. Most of these videos were not of high quality and created by the public. Medical professionals should be aware of misinformation permeating TikTok, given its large audience, and aim to promote or offer educational material of better accuracy and quality.

Surgeon Attitudes Toward Concurrent Urogynecologic and Gynecologic Oncology Procedures: A Cross-sectional Survey.

IMPORTANCE: There is increasing overlap in the urogynecologic and gynecologic oncologic patient populations. To improve patient advocacy and access to care, a collaborative surgical approach may benefit this cohort. OBJECTIVE: The aim of the study was to evaluate surgeon attitudes toward performing concurrent urogynecologic and gynecologic oncology procedures. We hypothesized that most surgeons are amenable to collaboration. STUDY DESIGN: We conducted a cross-sectional questionnaire of members of the Society of Gynecologic Oncology and the American Urogynecologic Society from August to November 2020. A 23-item online survey was created to assess surgeon demographics, practice and screening patterns, and attitudes toward surgical collaboration. We also evaluated obstacles to performing joint procedures and assessed whether attitudes could be influenced by new information. RESULTS: A total of 338 surveys were included in the analysis, including 158 urogynecologists and 226 gynecologic oncologists (GOs). Most surgeons (77.8%) will recommend concurrent procedures with another specialty, and 97.8% of urogynecologists and 95.7% of oncologists currently perform joint surgical procedures. Male surgeons, regardless of specialty, were more likely to recommend staged procedures (44% vs 31%, P < 0.001), as were GOs (28% vs 10.1%, P < 0.001). However, oncologists were more likely than urogynecologists to initiate referrals for surgical collaboration (33.3% vs 14.4%, P < 0.001). CONCLUSIONS: A total of 22.2% of urogynecologists and oncologists prefer staging surgical procedures. The most common barrier to a combined procedure was logistics. Urogynecologists were more concerned about the effects of cancer treatments on healing, the use of mesh implants, and financial reimbursements as compared with GOs. Treatment delay was a significantly greater concern for the oncologists.

Evaluation of the histological and biomechanical properties of poly-4-hydroxybutyrate scaffold for pelvic organ prolapse, compared with polypropylene mesh in a rabbit model.

INTRODUCTION AND HYPOTHESIS: Poly-4-hydroxybutyrate (P4HB) is a biopolymer produced by Escherichia coli K12 bacteria. P4HB is fully resorbed in vivo by 18-24 months post-implantation. The aim of this study is to evaluate P4HB in the rabbit abdomen and vagina to determine that the biomechanical and histological properties are similar to the standard polypropylene mesh. Our hypothesis is that the histological and biomechanical properties of a fully absorbable graft will be similar to a lightweight polypropylene (PP) mesh when implanted in rabbit vagina and abdomen. METHODS: Sixteen (n = 16) female New Zealand White (retired breeder) rabbits were equally divided between two time points (3 and 9 months). A total of 17 rabbits were used owing to one death secondary to suspected cardiomyopathy. P4HB scaffold and PP mesh were subcutaneously and peri-vaginally implanted into the rabbit abdomen and vagina respectively. All rabbits had both posterior and anterior vaginal implants, and half of the rabbits had four abdominal implants in addition to the vaginal implants. The abdominal implants were 4.5 cm long × 1.5 cm wide whereas the vaginal implants were 1.5 cm long × 0.5 cm wide. At 3 and 9 months, gross necropsy was performed and samples were obtained, sectioned, stained and evaluated via histological analysis. Specimens were assessed for host inflammatory response, neovascularization, elastin content, and collagen deposition/maturation. Specimens were also biomechanically evaluated via uniaxial tensile test to determine the stiffness, ultimate tensile strength and load at ultimate tensile strength of the device/tissue composite. RESULTS: No abdominal mesh exposures were noted. A comparable number of asymptomatic partial vaginal exposures were observed at 3 months (P4HB: n = 3; PP: n = 2) and 9 months (P4HB: n = 3; PP: n = 2) respectively. Histological analysis of specimens showed comparable results in the P4HB and PP groups at 3 and 9 months post-implantation. Although no acute inflammation was seen, chronic inflammation was demonstrated in all specimens. Elastic fibers were present in the 3-month vaginal PP and P4HB specimens, but were not seen again. There was an increase in type I/III collagen noted over time. Biomechanical evaluation of the vaginal mesh tissue complex showed ultimate tensile strength was not significantly different between P4HB and PP groups at 3 (P = 0.625) and 9 months (P = 0.250) respectively. CONCLUSIONS: P4HB scaffold may represent a fully absorbable alternative to permanent mesh for pelvic organ prolapse (POP) repair.

Prevalence of stress urinary incontinence and intrinsic sphincter deficiency in patients with stage IV pelvic organ prolapse.

AIM: To determine the prevalence of stress urinary incontinence (SUI) and intrinsic sphincter deficiency (ISD) in women with stage IV pelvic organ prolapse. METHODS: Retrospective analysis of women with stage IV prolapse who underwent multichannel urodynamic testing. Abdominal leak point pressures (ALPP) and maximum urethral closure pressures (MUCP) were recorded. ISD was defined as ALPP ≤60 cm of water and/or MUCP ≤20 cm of water. Percentages were used to present the proportion of subjects diagnosed with SUI and ISD. RESULTS: A total of 145 patients met inclusion criteria. Mean age was 69 years; most patients were Caucasian (56%). Eighty-two (56%) patients were found to have SUI on urodynamic testing. Thirty-six (44%) of these were asymptomatic and identified as having occult SUI. Sixteen (19.5%) patients were diagnosed with ISD using ALPP and/or MUCP. Six (37%) of the ISD patients had at least one MUCP value ≤20 cm of water and 12 (75%) had observed leakage with at least one ALPP value ≤60 cm of water. The number of patients with leakage at ALPP ≤60 cm of water increased with increasing bladder volumes. Five ISD patients (31%) had ALPP ≤60 cm of water at 200 mL, six (37.5%) had ALPP ≤60 cm of water at 300 mL and seven (43.8%) had ALPP ≤60 cm of water at 400 mL. CONCLUSION: Greater than 50% of patients with stage IV pelvic organ prolapse had SUI on urodynamic testing, and 20% were found to have ISD. Of the patients diagnosed with SUI, 40% were asymptomatic. These findings may assist in counseling and preoperative planning for women with stage IV prolapse.

#Urogyn: What's Trending on Instagram? A Cross-sectional Observational Study.

OBJECTIVE: The aim of the study was to identify the prevalence, authorship, and type of information pertaining to topics in urogynecology on Instagram via hashtag and content analysis. METHODS: A list of 20 hashtags consisting of common urogynecologic diagnoses, procedures, and lay terms was derived from the American Urogynecologic Society's "Patient Fact Sheets." The top 9 and most recent 30 posts for each hashtag were reviewed for authorship and content type. Content type was divided into the following categories: educational; tagged but unrelated posts; pertinent patient experiences; community building and outreach; advertisements; and humor. Searches were limited to English language posts. RESULTS: Our search yielded 561,133 posts. The 5 most popular hashtags were pelvic floor (30.6%, n = 171,855), interstitial cystitis (12.8%, n = 71,977), pelvic pain (10.0%, n = 56,505), incontinence (9.3%, n = 52,169), and prolapse (3.9%, n = 21,839). The authorship of the top 9 and most recent 30 posts (n = 537) were as follows: patients (34.6%, n = 186), allied health professionals (29.2%, n = 157), physicians (13.4%, n = 72), and other (22.7%, n = 122). Further authorship and content analysis revealed that allied health professionals authored the most informational posts (45.6%, n = 129) and patients authored the most unrelated (69.4%, n = 43), patient experience (81.7%, n = 125), community building (55.8%, n = 53), and humorous posts (38.5%, n = 10). CONCLUSIONS: More than 500,000 posts related to urogynecology were identified on Instagram. Most posts were authored by patients and allied health professionals with a small contribution from physicians. Greater physician participation may increase the quantity of educational posts and offer a low-cost platform for networking and connecting with patients and other providers.

Comparing Force of Stream With a Standard Fill Voiding Trial After Surgical Repair of Apical Prolapse: A Randomized Controlled Trial.

OBJECTIVE: To estimate whether the urinary force of stream method is noninferior to a standard fill voiding trial for rate of catheterization within 6 weeks after apical prolapse surgery in those discharged without a catheter. METHODS: A noninferiority randomized controlled trial was conducted in postoperative women comparing force of stream with standard fill voiding trials after vaginal, abdominal, or laparoscopic-robotic apical pelvic organ prolapse (POP) surgery. Before discharge, women in both groups were backfilled with 300 mL normal saline. Successful voiding criteria in the force of stream group was subjective force of stream of at least 50 using a visual analog scale; reporting less than 50 prompted a bladder scan. Successful voiding was defined as a postvoid residual volume of less than 500 mL. For the standard fill voiding trial group, voiding two thirds of the instilled amount indicated success. The primary outcome was the rate of catheterization within the 6-week postoperative period after surgical repair of apical prolapse among those discharged without a urinary catheter. Secondary endpoints included trial of void failure rates. A sample size of 59 patients per group who passed trial of void at discharge was needed to achieve 80% power using a noninferiority margin (delta of 10%). Total enrollment of 169 patients was necessary to account for an estimated 30% trial of void failure rate. RESULTS: From April 2016 and April 2017, 184 patients were enrolled (six enrolled before the trial registration date), with the first patient enrolled on April 1, 2016. One hundred seventy-four patients were randomized (86 in the force of stream group and 88 in the standard fill voiding trial group). No differences were observed in demographic or perioperative characteristics, except for stage 2 apical prolapse (52% in the force of stream group vs 36% in the standard fill voiding trial group). For the primary outcome, similar rates were found in those patients who passed their trial of void but subsequently needed catheterization for voiding dysfunction (force of stream 2.8% [2/71] vs standard fill voiding trial 3.1% [2/64]; difference -0.3%, 95% CI -8.69% to 8.08%). The incidence of trial of void failures at discharge was similar (force of stream 17.4% [15/86] vs standard fill voiding trial 26.4% [23/87]; risk ratio 0.65, 95% CI 0.37-1.18, P=nonsignificant). CONCLUSION: Force of stream was noninferior to standard fill voiding trial when comparing the rate of catheter insertion during the 6-week postoperative period after apical POP surgery in those discharged without a catheter. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT02753920.

A randomized controlled trial comparing two voiding trials after midurethral sling with or without colporrhaphy.

INTRODUCTION AND HYPOTHESIS: To compare the force of the stream (FOS) voiding trial with the standard voiding trial (SVT) after outpatient midurethral sling (MUS) whether or not colporrhaphy was performed. METHODS: This is a randomized controlled non-inferiority trial of patients scheduled for MUS or colporrhaphy. Sample size of 102 patients was calculated for 80% power. Patients were randomized to FOS or SVT. Primary outcome was the number of unexpected postoperative visits (UPOVs) for voiding dysfunction (VD) or urinary tract infection (UTI). Voiding dysfunction was defined as urinary retention or post-void residual (PVR) > 200 cc. Subjects rated FOS using a visual analog scale (VAS). Criterion for non-inferiority was an upper limit of < 10% for the 95% CI. Analyses were performed using SAS version 9.4 (SAS Institute. Cary, NC). RESULTS: One hundred two subjects were included (49 FOS, 53 SVT). Immediate postoperative catheterization for FOS and SVT was 8.2% (n = 4) and 9.4% (n = 5), respectively. Recovery time was significantly less for FOS versus SVT (p = 0.0002). Total UPOVs were five (10.2%) and two (3.8%) for FOS and SVT, respectively. Two FOS subjects who had MUS + colporrhaphy passed their VT and had subsequent UPOVs for VD. No evidence of non-inferiority was noted when comparing FOS to SVT for total UPOVs: CI: 6.0% (-5.2, 17.2) for postoperative VD [CI: 6.1% (-4.0, 16.2)] or UTIs [CI: 0.3% (-9.4, 10.1)]. CONCLUSIONS: No evidence of non-inferiority was noted comparing FOS with SVT for unexpected postoperative visits for voiding dysfunction or UTI. This study shows the need for larger studies to assess the use of the FOS method in patients undergoing surgery for prolapse with or without MUS.

Comparison of strength of sacrocolpopexy mesh attachment using barbed and nonbarbed sutures.

INTRODUCTION AND HYPOTHESIS: We aimed to assess the pull-out strength of barbed and nonbarbed sutures used in sacrocolpopexy mesh fixation. We hypothesized there are no differences in the force needed to dislodge mesh from tissue using barbed and nonbarbed sutures of similar size. METHODS: Using the rectus fascia of three unembalmed cadavers, a 6 × 3 cm strip of polypropylene mesh was anchored to the fascia with sutures. The barbed sutures investigated were 2-0 V-Loc 180 (nine trials) and 3-0 bidirectional Quill™ SRS PDO (five trials). The nonbarbed sutures included 2-0 PDS (nine trials), CV-2 GORE-TEX (nine trials) and 2-0 Prolene (nine trials). The free-end of the mesh was anchored to a pulley system fixed to a tensiometer to measure the peak force applied at the moment of mesh dislodgement (termed the pull-out force). The pull-out force was recorded. Continuous variables are presented as medians and interquartile ranges (IQR). Analysis of variance was used to compare the forces across the suture types. RESULTS: The highest pull-out force observed was with GORE-TEX (median 65.14 N, IQR 53.37-68.77 N) followed by Prolene (median 58.98 N, IQR 54.64-62.59 N), V-Loc (median 55.23 N, IQR 51.60-58.57 N), PDS (53.96 N, IQR 51.60-57.88 N), and Quill (44.44 N, IQR 17.27-47.38 N). All 2-0 and CV-2 caliber sutures had greater pull-out forces than 3-0 Quill sutures (p < 0.01). No significant differences in pull-out forces were observed between 2-0 and CV-2 caliber sutures (p > 0.05). In 35 of the 41 trials (85%), the mesh sheared from the tissue. CONCLUSION: CV-2 ad 2-0 barbed and nonbarbed sutures had similar pull-out forces in an assessment of mesh fixation strength.

Inflammatory Urinary Cytokine Expression and Quality of Life in Patients With Overactive Bladder.

OBJECTIVE: The aims of this study were to analyze levels of selected inflammatory urinary cytokines/chemokines in subjects with overactive bladder (OAB) and to determine if cytokine/chemokine levels correlate with quality of life and symptom distress. METHODS: This prospective, case-control pilot analysis included 23 women with OAB and 22 control subjects. Overactive bladder subjects were enrolled if they had symptoms of urinary frequency, urgency, or urge incontinence for more than 3 months and urodynamic evidence of detrusor overactivity. Control subjects denied urinary symptoms. Subjects and control subjects were excluded if they had known inflammatory bladder or systemic conditions, cystitis, stones, or recent anticholinergic use. Urine samples were collected from each subject and control. Subjects filled out the Incontinence Quality of Life Questionnaire and the Urinary Distress Inventory Questionnaire 6. Cytokine/chemokine levels were determined using the multiplexed Meso Scale Discovery Platform and were corrected for urinary creatinine concentrations. Statistical analysis comparing cytokine/chemokine levels was performed using the Mann-Whitney U test; relationships between cytokine/chemokine and questionnaire scores were calculated with Spearman correlation coefficient. RESULTS: Subjects with OAB had significantly lower urinary interleukin 10 (IL-10), IL-12-p70, and IL-13 levels compared with control subjects. Interleukin 1 correlated with worsening symptom distress on Urinary Distress Inventory Questionnaire 6. CONCLUSIONS: To our knowledge, this is at present the only study correlating inflammatory cytokine/chemokine levels in women with OAB with quality of life and distress. Interleukin 1 signified worsening distress, whereas IL-10, IL-12p70, and IL-13 were the only cytokines found at different levels in subjects. Our findings support a larger study in order to evaluate the value of urinary cytokines/chemokines as potential biomarkers.

Faecal incontinence: a narrative review of clinic-based management for the general gynaecologist.

The objective of this article is to provide an informative and narrative review for the general Gynaecologist regarding the pathophysiology and conservative treatments available for faecal incontinence (FI). A PubMed search was performed by library staff and an author using the keywords: anal incontinence, faecal incontinence, accidental bowel leakage, outpatient clinic management of faecal incontinence and defecatory dysfunction. As the social limitations of FI can be devastating and long-term patient satisfaction rates after anal sphincteroplasty remain reportedly-low, the role of clinic-based management of FI has continued to grow. The purpose of this article is to provide the Obstetrician and Gynaecologist with a basic template for screening, evaluation and management of faecal incontinence in the clinical setting.

Pessary types and discontinuation rates in patients with advanced pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to investigate factors associated with long-term pessary use in patients with advanced pelvic organ prolapse (POP). METHODS: This was a retrospective chart review of patients with POP of stage ≥2 managed with a pessary. Patients were excluded if the date of fitting or follow-up was unavailable. Long-term use was defined as more than 1 year. Patient demographics, pessary fitting, and follow-up visit dates were collected. The primary end point was the duration of use and the prognostic impact of pessary type. Secondary objectives addressed other influencing factors including age, estrogen use, and prolapse stage. The data were analyzed using SPSS version 21. RESULTS: The final analysis included 311 patients. The mean (± standard deviation, SD) duration of pessary use was 7.0 ± 0.72 years (median 5.7 years). Long-term use was found in 76 % (164) of these patients. Factors associated with longer use were age >65 years (p = 0.004) and estrogen use (p = 0.048). The estimated mean (± SD) durations of use of the Gellhorn, open ring, ring with support, cube and donut pessaries were 10.5 ± 0.7 years, 3.4 ± 0.6 years, 1.8 ± 0.2 years, 1.8 ± 0.3 years and 1.7 ± 0.5 years, respectively. The Gellhorn pessary was associated with significantly longer use than other pessary types (10.5 ± 0.7, p < 0.0000001); this finding was independent of age, prolapse stage, hysterectomy, and vaginal estrogen use. CONCLUSIONS: In this retrospective analysis, the duration of use was longest with the Gellhorn pessary. Older age and vaginal estrogen use were associated with longer pessary use.

The prevalence of microscopic hematuria in a cohort of women with pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: In 2012, the American Urological Association (AUA) revised its guidelines for microscopic hematuria (MH). We hypothesize that the prevalence of MH is greater in women with pelvic organ prolapse than in the general population. METHODS: All patients presenting to an outpatient urogynecological center with prolapse between January 2008 and December 2011 were reviewed. Exclusion criteria included: pregnancy, presence of gross hematuria, menses, or urological pathology. MH was defined as ≥3 red blood cells per high power field on one urinalysis specimen with a negative urine culture, and the prevalence of MH was calculated. Statistical analysis was performed. RESULTS: One thousand and forty women with pelvic organ prolapse were included in the analysis. Mean age was 64.1 years (range 20 to 96) and mean parity was 2.7 (range 0 to 12). Two hundred and nine out of 1,040 met the criteria for MH. No cases of urological malignancy were diagnosed in patients who underwent further workup. One hundred and ninety-seven patients with MH (93.4 %) had cystoceles on examination. CONCLUSIONS: This is the largest study to investigate MH in women with prolapse based on the new guidelines. The prevalence of MH was 20.1 % in our study population. Cystoscopy, renal function testing, and CT urography are now recommended after one positive urinalysis, regardless of gender or the presence of prolapse. Owing to the low incidence of urological malignancy detected as well as the increased prevalence of MH found in women with prolapse, specific guidelines for the management of MH in this population are needed.

The effect of collection method on urinalysis results in women with pelvic organ prolapse.

Midstream clean catch and catheterized urine specimens were obtained for each patient and samples were compared by microscopic urinalysis. The results of this study demonstrate that a midstream clean catch does not yield accurate urinalysis results in women with advanced urogenital prolapse.

Sacral nerve stimulation reduces elevated urinary nerve growth factor levels in women with symptomatic detrusor overactivity.

OBJECTIVES: To investigate changes in urinary nerve growth factor (uNGF) in women with symptomatic detrusor overactivity (DO) following peripheral nerve evaluation (PNE) for sacral neuromodulation vs controls. STUDY DESIGN: There were 23 subjects with overactive bladder symptoms and DO who failed management with anticholinergics and 22 controls consented to participate in this prospective pilot study. Urine specimens were collected from controls at baseline for evaluation of uNGF and creatinine. Subjects were evaluated at baseline and 5 days after a trial of sacral nerve stimulation referred to as a PNE. Each visit included urine collection for uNGF and, Incontinence Quality of Life Questionnaire, Urinary Distress Inventory Questionnaire, postvoid residual volume, and a 3-day voiding diary. uNGF levels were measured by enzyme-linked immunosorbent assay and expressed as uNGF pg/creatinine mg. RESULTS: Subjects with DO had significantly higher baseline uNGF levels (corrected for creatinine) compared with controls (19.82 pg/mg vs 7.88 pg/mg, P < .002). Seventeen DO subjects underwent PNE and were evaluated at the end of the testing period. There was a significant improvement in quality of life scores for subjects after PNE compared with baseline (Urinary Distress Inventory Questionnaire: 7.0 vs 13.7, P < .001; Incontinence Quality of Life Questionnaire: 87.3 vs 52.8, P < .0001). Concordantly, uNGF levels significantly decreased from 17.23 pg/mg to 9.24 pg/mg (P < .02) after PNE. CONCLUSION: uNGF levels decrease with symptomatic response in DO subjects undergoing PNE. DO subjects had significantly higher uNGF at baseline vs controls, and uNGF levels significantly decreased after only 5 days of sacral nerve stimulation. These findings support a larger study to validate the use of uNGF as an objective tool to assess therapeutic outcome in patients undergoing PNE for sacral neuromodulation.

Visualization of synthetic mesh utilizing optical coherence tomography.

INTRODUCTION AND HYPOTHESIS: Owing to the recent upsurge in adverse events reported after mesh-augmented pelvic organ prolapse (POP) repairs, our aim was to determine whether the location and depth of synthetic mesh can be measured postoperatively within the vaginal tissue microstructure using optical coherence tomography (OCT). METHODS: Seventeen patients with prior mesh-augmented repairs were recruited for participation. Patients were included if they had undergone an abdominal sacral colpopexy (ASC) or vaginal repair with mesh. Exclusion criteria were a postoperative period of <6 months, or the finding of mesh exposure on examination. OCT was used to image the vaginal wall at various POP-Q sites. If mesh was visualized, its location and depth was calculated and recorded. RESULTS: Ten patients underwent ASC and 7 patients had 8 transvaginal mesh repairs. Mesh was visualized in 16 of the 17 patients using OCT. In all ASC patients, mesh was imaged centrally at the posterior apex. In patients with transvaginal mesh in the anterior and/or posterior compartments, the mesh was visualized directly anterior and/or posterior to the apex respectively. Mean depth of the mesh in the ASC, anterior, and posterior groups was 60.9, 146.7, and 125.7 µm respectively. Mesh was visualized within the vaginal epithelial layer in all 16 patients despite the route of placement. CONCLUSION: In this pilot study we found that OCT can be used to visualize polypropylene mesh within the vaginal wall following mesh-augmented prolapse repair. Regardless of abdominal versus vaginal placement, the mesh was identified within the vaginal epithelial layer.
