Health Care Workers Online YouTube Content Compared to AUA Prevention of Recurrent Urinary Tract Infections in Women Guidelines: An Integrative Review of Quality and Comprehensiveness Analysis. UROLOGY PRACTICE 2024; 11:498-505. [PMID: 38447214 DOI: 10.1097/upj.0000000000000537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 01/19/2024] [Indexed: 03/08/2024]
Abstract
INTRODUCTION We document the quality, veracity, and comprehensiveness of recurrent UTI information on YouTube to increase health care workers' (HCWs') awareness of UTI-related content online, and to identify deficits in understanding, clarify misconceptions, and reduce stigmatization risk. METHODS High-traffic topic search terms were curated by Google Trends to extract 200 videos, of which 45 met inclusion criteria. Five independent reviewers used a standardized questionnaire based on the AUA recurrent UTI guidelines to assess the definition of UTI, marketing content, prophylaxis/prevention strategies, and antibiotic use/stewardship. RESULTS Incongruent or incomplete guideline UTI definitions were found in 78% (35/45) of videos (K = 0.40), despite 80% (36/45) being authored by HCWs. Forty-two percent (19/45) promoted nonguideline-based hygiene practices; 25% (11/45) advocated front-to-back wiping (K = 0.71). Descriptors identified within the videos included the mention of women with UTI as unclean. Only 55% (25/45) discussed increasing fluid intake (K = 0.59), while 33% (15/45) discussed the use of cranberry supplementation (K = 0.81). CONCLUSIONS Discussion of hygiene practices which lack a specific guideline statement is particularly evident. Descriptors that characterize women with UTI as "unclean" may create a health equity concern for women experiencing UTIs. These findings should alert HCWs to the scope and emphasis in online education that patients may view to self-educate; both the errors and the issues of equity are problematic. Educational materials on UTI should be based on evidence-based guidelines, such as those by the AUA.

Abstract
IMPORTANCE The utility of pudendal nerve blocks (PNBs) at the time of transvaginal surgery is mixed in the literature. No published study has evaluated the efficacy of PNB since the widespread adoption of Enhanced Recovery After Surgery (ERAS) pathways. OBJECTIVE This study aimed to determine if PNB, in addition to ERAS measures, at the time of vaginal reconstructive surgery reduces opioid use in the immediate postoperative period. STUDY DESIGN In this randomized, blinded, controlled trial, women scheduled for transvaginal multicompartment prolapse repair were randomized to bilateral PNB before incision with 20 mL of 0.5% bupivacaine versus usual care. Primary outcome was opioid use in morphine milligram equivalents (MME) for the first 24 hours. The study was powered to detect a 5.57-MME difference in opioid use in the first 24 hours between groups. RESULTS Forty-four patients were randomized from January 2020 to April 2022. The PNB and control groups were well matched in demographic and surgical data. There was no difference in opioid use in first 24 hours between the control and PNB groups (8 [0-20] vs 6.7 [0-15]; P = 0.8). Median pain scores at 24 and 48 hours did not differ between groups (4 ± 2 vs 3 ± 3; P = 0.44) and 90% of participants were satisfied with pain control across both groups. Time to return to normal activities (median, 10 days) was also not different between the groups. CONCLUSIONS Because pain satisfaction after transvaginal surgery in the era of ERAS is high, with overall low opioid requirements, PNB provides no additional benefit.

A Treatment Algorithm for High-Tone Pelvic Floor Dysfunction. Obstet Gynecol 2024; 143:595-602. [PMID: 38387036 PMCID: PMC10953682 DOI: 10.1097/aog.0000000000005536] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 11/27/2023] [Accepted: 12/08/2023] [Indexed: 02/24/2024]
Abstract
OBJECTIVE To develop evidence- and consensus-based clinical practice guidelines for management of high-tone pelvic floor dysfunction (HTPFD). High-tone pelvic floor dysfunction is a neuromuscular disorder of the pelvic floor characterized by non-relaxing pelvic floor muscles, resulting in lower urinary tract and defecatory symptoms, sexual dysfunction, and pelvic pain. Despite affecting 80% of women with chronic pelvic pain, there are no uniformly accepted guidelines to direct the management of these patients. METHODS A Delphi method of consensus development was used, comprising three survey rounds administered anonymously via web-based platform (Qualtrics XM) to national experts in the field of HTPFD recruited through targeted invitation between September and December 2021. Eleven experts participated with backgrounds in urology, urogynecology, minimally invasive gynecology, and pelvic floor physical therapy (PFPT) participated. Panelists were asked to rate their agreement with rated evidence-based statements regarding HTPFD treatment. Statements reaching consensus were used to generate a consensus treatment algorithm. RESULTS A total of 31 statements were reviewed by group members at the first Delphi round with 10 statements reaching consensus. 28 statements were reposed in the second round with 17 reaching consensus. The putative algorithm met clinical consensus in the third round. There was universal agreement for PFPT as first-line treatment for HTPFD. If satisfactory symptom improvement is reached with PFPT, the patient can be discharged with a home exercise program. If no improvement after PFPT, second-line options include trigger or tender point injections, vaginal muscle relaxants, and cognitive behavioral therapy, all of which can also be used in conjunction with PFPT. Onabotulinumtoxin A injections should be used as third line with symptom assessment after 2-4 weeks. There was universal agreement that sacral neuromodulation is fourth-line intervention. The largest identified barrier to care for these patients is access to PFPT. For patients who cannot access PFPT, experts recommend at-home, guided pelvic floor relaxation, self-massage with vaginal wands, and virtual PFPT visits. CONCLUSION A stepwise approach to the treatment of HTPFD is recommended, with patients often necessitating multiple lines of treatment either sequentially or in conjunction. However, PFPT should be offered first line.

Abstract
IMPORTANCE Given worsening global antibiotic resistance, antimicrobial stewardship aims to use the shortest effective duration of the most narrow-spectrum, effective antibiotic for patients with specific urinary symptoms and laboratory testing consistent with urinary tract infection (UTI). Inappropriate treatment and unnecessary antibiotic switching for UTIs harms patients in a multitude of ways. OBJECTIVE This study sought to analyze antibiotic treatment failures as measured by antibiotic switching for treatment of UTI in emergent and ambulatory care. STUDY DESIGN For this retrospective cohort study, 908 encounters during July 2019 bearing a diagnostic code for UTI/cystitis in a single health care system were reviewed. Urinary and microbiological testing, symptoms endorsed at presentation, and treatments prescribed were extracted from the medical record. RESULTS Of 908 patients diagnosed with UTI, 64% of patients (579/908) received antibiotics, 86% of which were empiric. All patients evaluated in emergent care settings were prescribed antibiotics empirically in contrast to 71% of patients in ambulatory settings (P < 0.001). Of patients given antibiotics, 89 of 579 patients (15%, 10% of all 908 patients) were switched to alternative antibiotics within 28 days. Emergent care settings and positive urine cultures were significantly associated with increased antibiotic switching. Patients subjected to switching tended to have higher rates of presenting symptoms inconsistent with UTI. CONCLUSIONS Empiric treatment, particularly in an emergent care setting, was frequently inappropriate and associated with increasing rates of antibiotic switching. Given the profound potential contribution to antibiotic resistance, these findings highlight the need for improved diagnostic and prescribing accuracy for UTI.

Validation of Distinct Bladder Pain Phenotypes Utilizing the MAPP Research Network Cohort. Int Urogynecol J 2024; 35:637-648. [PMID: 38300276 PMCID: PMC11023803 DOI: 10.1007/s00192-024-05735-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 01/03/2024] [Indexed: 02/02/2024]
Abstract
INTRODUCTION AND HYPOTHESIS As interstitial cystitis/bladder pain syndrome (IC/BPS) likely represents multiple pathophysiologies, we sought to validate three clinical phenotypes of IC/BPS patients in a large, multi-center cohort using unsupervised machine learning (ML) analysis. METHODS Using the female Genitourinary Pain Index and O'Leary-Sant Indices, k-means unsupervised clustering was utilized to define symptomatic phenotypes in 130 premenopausal IC/BPS participants recruited through the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) research network. Patient-reported symptoms were directly compared between MAPP ML-derived phenotypic clusters to previously defined phenotypes from a single center (SC) cohort. RESULTS Unsupervised ML categorized IC/BPS participants into three phenotypes with distinct pain and urinary symptom patterns: myofascial pain, non-urologic pelvic pain, and bladder-specific pain. Defining characteristics included presence of myofascial pain or trigger points on examination for myofascial pain patients (p = 0.003) and bladder pain/burning for bladder-specific pain patients (p < 0.001). The three phenotypes were derived using only 11 features (fGUPI subscales and ICSI/ICPI items), in contrast to 49 items required previously. Despite substantial reduction in classification features, unsupervised ML independently generated similar symptomatic clusters in the MAPP cohort with equivalent symptomatic patterns and physical examination findings as the SC cohort. CONCLUSIONS The reproducible identification of IC/BPS phenotypes, distinguishing bladder-specific pain from myofascial and genital pain, using independent ML analysis of a multicenter database suggests these phenotypes reflect true pathophysiologic differences in IC/BPS patients.

The Persistency Index: a novel screening tool for identifying myofascial pelvic floor dysfunction in patients seeking care for lower urinary tract symptoms. Am J Obstet Gynecol 2023; 229:667.e1-667.e11. [PMID: 37633575 PMCID: PMC11000817 DOI: 10.1016/j.ajog.2023.08.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 07/31/2023] [Accepted: 08/16/2023] [Indexed: 08/28/2023]
Abstract
BACKGROUND Patients with myofascial pelvic floor dysfunction often present with lower urinary tract symptoms, such as urinary frequency, urgency, and bladder pressure. Often confused with other lower urinary tract disorders, this constellation of symptoms, recently termed myofascial urinary frequency syndrome, is distinct from other lower urinary tract symptoms and optimally responds to pelvic floor physical therapy. A detailed pelvic floor myofascial examination performed by a skilled provider is currently the only method to identify myofascial urinary frequency syndrome. Despite a high influence on quality of life, low awareness of this condition combined with no objective diagnostic testing leads to the frequent misdiagnosis or underdiagnosis of myofascial urinary frequency syndrome. OBJECTIVE This study aimed to develop a screening measure to identify patients with myofascial urinary frequency syndrome (bothersome lower urinary tract symptoms secondary to myofascial pelvic floor dysfunction) from patient-reported symptoms. STUDY DESIGN A population of patients with isolated myofascial urinary frequency syndrome was identified by provider diagnosis from a tertiary urology practice and verified by standardized pelvic floor myofascial examination and perineal surface pelvic floor electromyography. Least Angle Shrinkage and Selection Operator was used to identify candidate features from the Overactive Bladder Questionnaire, Female Genitourinary Pain Index, and Pelvic Floor Distress Index predictive of myofascial urinary frequency syndrome in a pooled population also containing subjects with overactive bladder (n=42), interstitial cystitis/bladder pain syndrome (n=51), and asymptomatic controls (n=54) (derivation cohort). A simple, summated score of the most discriminatory questions using the original scaling of the Pelvic Floor Distress Index 5 (0-4) and Genitourinary Pain Index 5 (0-5) and modified scaling of Female Genitourinary Pain Index 2b (0-3) had an area under the curve of 0.75. As myofascial urinary frequency syndrome was more prevalent in younger subjects, the inclusion of an age penalty (3 points added if under the age of 50 years) improved the area under the curve to 0.8. This score was defined as the Persistency Index (possible score of 0-15). The Youden Index was used to identify the optimal cut point Persistency Index score for maximizing sensitivity and specificity. RESULTS Using a development cohort of 215 subjects, the severity (Pelvic Floor Distress Index 5) and persistent nature (Female Genitourinary Pain Index 5) of the sensation of incomplete bladder emptying and dyspareunia (Female Genitourinary Pain Index 2b) were the most discriminatory characteristics of the myofascial urinary frequency syndrome group, which were combined with age to create the Persistency Index. The Persistency Index performed well in a validation cohort of 719 patients with various lower urinary tract symptoms, including overactive bladder (n=285), interstitial cystitis/bladder pain syndrome (n=53), myofascial urinary frequency syndrome (n=111), controls (n=209), and unknown diagnoses (n=61), exhibiting an area under the curve of 0.74. A Persistency Index score ≥7 accurately identified patients with myofascial urinary frequency syndrome from an unselected population of individuals with lower urinary tract symptoms with 80% sensitivity and 61% specificity. A combination of the Persistency Index with the previously defined Bladder Pain Composite Index and Urge Incontinence Composite Index separated a population of women seeking care for lower urinary tract symptoms into groups consistent with overactive bladder, interstitial cystitis/bladder pain syndrome, and myofascial urinary frequency syndrome phenotypes with an overall diagnostic accuracy of 82%. CONCLUSION Our study recommends a novel screening method for patients presenting with lower urinary tract symptoms to identify patients with myofascial urinary frequency syndrome. As telemedicine becomes more common, this index provides a way of screening for myofascial urinary frequency syndrome and initiating pelvic floor physical therapy even before a confirmatory pelvic examination.

Abstract
Anticholinergics have been used in the treatment of overactive bladder (OAB), but their use is limited by poor tolerability and anticholinergic-related side effects. Increasingly, providers are discontinuing anticholinergic prescribing because of growing evidence of the association of anticholinergic use with increased risk of cognitive decline and other adverse effects. Newer medications for OAB, the β3-adrenergic receptor agonists mirabegron and vibegron, do not have anticholinergic properties and are typically well tolerated; however, many insurance plans have limited patient access to these newer OAB medications by requiring step therapy, meaning less expensive anticholinergic medications must be trialed and/or failed before a β3-agonist will be covered and dispensed. Thus, many patients are unable to easily access these medications. Step therapy and other drug utilization strategies (e.g., prior authorization) are often used to manage the growing costs of pharmaceuticals, but these policies do not always follow treatment guidelines and may harm patients as a result of treatment delays, discontinuations, or related increases in adverse events. Medical professionals have called for reform of drug utilization strategies through partnerships that include clinicians and policymakers. This narrative review discusses prescribing patterns for OAB treatment and the effect of switching between drugs, as well as the costs of step therapy and prior authorization on patients and prescribers.

Abstract
This study describes a novel, distinct phenotype of urinary symptoms named "myofascial urinary frequency syndrome" (MUFS) present in one-third of individuals presenting with urinary frequency. In addition to a characteristic symptom constellation suggestive of myofascial dysfunction, MUFS subjects exhibit "persistency": a persistent feeling of needing to urinate regardless of urine volume. On examination, 97% of MUFS patients demonstrated pelvic floor hypertonicity with either global tenderness or myofascial trigger points, and 92% displayed evidence of impaired muscular relaxation, hallmarks of myofascial dysfunction. To confirm this symptom pattern was attributable to the pelvic floor musculature, we confirmed the presence of "persistency" in 68 patients with pelvic floor myofascial dysfunction established through comprehensive examination and electromyography and corroborated by improvement with pelvic floor myofascial release. These symptoms distinguish subjects with myofascial dysfunction from subjects with OAB, IC/BPS, and asymptomatic controls, confirming MUFS is a distinct LUTS symptom complex.

Abstract
IMPORTANCE Effective opioid-sparing postoperative analgesia requires a multimodal approach. Regional nerve blocks augment pain control in many surgical fields and may be applied to pelvic floor reconstruction. OBJECTIVE This study aimed to evaluate the impact of pudendal nerve block on postoperative pain control and opioid consumption after vaginal surgery. STUDY DESIGN In this randomized, double-blind, sham-controlled trial, we enrolled women undergoing pelvic reconstruction, excluding patients with chronic pelvic pain or contraindications to nonnarcotic analgesia. Patients were randomized to transvaginal pudendal nerve block (9 mL 0.25% bupivacaine and 1 mL 40 mg/mL triamcinolone) or sham injection (10 mL normal saline). Primary outcomes were pain scores and opioid requirements. Sixty patients were required to show a 20-mm difference on a 100-mm visual analog scale (VAS). RESULTS We randomized 71 patients: 36 pudendal block and 35 sham. Groups were well matched in baseline characteristics and surgery type. Prolapse repairs were most common (n = 63 [87.5%]), and there was no difference in anesthetic dose or operative time. Pain scores were equivalent in the postanesthesia care unit (mean VAS, 53.1 [block] vs 56.4 [sham]; P = 0.517) and on postoperative day 4 (mean VAS, 26.7 [block] vs 35.5 [sham]; P = 0.131). On postoperative day 1, the intervention group reported less pain, but this did not meet our 20 mm goal for clinical significance (mean VAS, 29.2 vs 42.5; P = 0.047). A pudendal block was associated with lower opioid consumption at all time points, but this was not statistically significant. CONCLUSIONS Surgeon-administered pudendal nerve block at the time of vaginal surgery may not significantly improve postoperative pain control or decrease opioid use.

Abstract
Background Patients presenting with lower urinary tract symptoms (LUTS) are historically classified to several symptom clusters, primarily overactive bladder (OAB) and interstitial cystitis/bladder pain syndrome (IC/BPS). Accurate diagnosis, however, is challenging due to overlapping symptomatic features, and many patients do not readily fit into these categories. To enhance diagnostic accuracy, we previously described an algorithm differentiating OAB from IC/BPS. Herein, we sought to validate the utility of this algorithm for identifying and classifying a real-world population of individuals presenting with OAB and IC/BPS and characterize patient subgroups outside the traditional LUTS diagnostic paradigm. Methods An Exploratory cohort of 551 consecutive female subjects with LUTS evaluated in 2017 were administered 5 validated genitourinary symptom questionnaires. Application of the LUTS diagnostic algorithm classified subjects into controls, IC/BPS, and OAB, with identification of a novel group of highly bothered subjects lacking pain or incontinence. Symptomatic features of this group were characterized by statistically significant differences from the OAB, IC/BPS and control groups on questionnaires, comprehensive review of discriminate pelvic exam, and thematic analysis of patient histories. In a Reassessment cohort of 215 subjects with known etiologies of their symptoms (OAB, IC/BPS, asymptomatic microscopic hematuria, or myofascial dysfunction confirmed with electromyography), significant associations with myofascial dysfunction were identified in a multivariable regression model. Pre-referral and specialist diagnoses for subjects with myofascial dysfunction were catalogued. Findings Application of a diagnostic algorithm to an unselected group of 551subjects presenting for urologic care identified OAB and IC/BPS in 137 and 96 subjects, respectively. An additional 110 patients (20%) with bothersome urinary symptoms lacked either bladder pain or urgency characteristic of IC/BPS and OAB, respectively. In addition to urinary frequency, this population exhibited a distinctive symptom constellation suggestive of myofascial dysfunction characterized as "persistency": bothersome urinary frequency resulting from bladder discomfort/pelvic pressure conveying a sensation of bladder fullness and a desire to urinate. On examination, 97% of persistency patients demonstrated pelvic floor hypertonicity with either global tenderness or myofascial trigger points, and 92% displayed evidence of impaired muscular relaxation, hallmarks of myofascial dysfunction. We therefore classified this symptom complex "myofascial frequency syndrome". To confirm this symptom pattern was attributable to the pelvic floor, we confirmed the presence of "persistency" in 68 patients established to have pelvic floor myofascial dysfunction through comprehensive evaluation corroborated by symptom improvement with pelvic floor myofascial release. These symptoms distinguish subjects with myofascial dysfunction from subjects with OAB, IC/BPS, and asymptomatic controls, confirming that myofascial frequency syndrome is a distinct LUTS symptom complex. Interpretation This study describes a novel, distinct phenotype of LUTS we classified as myofascial frequency syndrome in approximately one-third of individuals with urinary frequency. Common symptomatic features encompass elements in other urinary syndromes, such as bladder discomfort, urinary frequency and urge, pelvic pressure, and a sensation of incomplete emptying, causing significant diagnostic confusion for providers. Inadequate recognition of myofascial frequency syndrome may partially explain suboptimal overall treatment outcomes for women with LUTS. Recognition of the distinct symptom features of MFS (persistency) should prompt referral to pelvic floor physical therapy. To improve our understanding and management of this as-yet understudied condition, future studies will need to develop consensus diagnostic criteria and objective tools to assess pelvic floor muscle fitness, ultimately leading to corresponding diagnostic codes.

Abstract
INTRODUCTION We sought to determine rates of pelvic organ prolapse (POP) recurrence following pregnancy and delivery in reproductive-age women with prior hysteropexy. METHODS Scopus, MEDLine, EMBASE, Cochrane Library, and ClinicalTrials.gov databases were searched from inception to May 2020 for combinations of any of the keywords: "pregnancy", "delivery", "fertility", or "cesarean" with a comprehensive list of uterine-sparing surgical procedures for POP repair. Using approach, 1,817 articles were identified describing surgical, uterine-sparing POP repair techniques and subsequent pregnancy and delivery outcomes in reproductive-age women. RESULTS: Twenty-seven studies describing 218 pregnancies, including 215 deliveries and 3 abortions, were summarized using narrative review and descriptive statistics. Successful pregnancies were reported following a diverse range of uterine-sparing prolapse repairs, both native tissue and mesh-augmented, that utilized vaginal, open abdominal, and laparoscopic approaches. We observed shifts from native tissue repairs to mesh-augmented laparoscopic repairs over time. POP recurrence occurred in 12% of subjects overall, 15% after vaginal and 10% after abdominal prolapse repairs. While meta-analysis identified higher recurrence rates after vaginal delivery (15%) than cesarean section (10%), due to small study numbers, multiple confounders, and heterogeneity between studies, no significant differences in recurrence rates could be identified between vaginal and abdominal surgical approaches, utilization of mesh augmentation, or mode of delivery. CONCLUSION Although literature on pregnancy following uterine-sparing POP repair is limited, available data suggest that prolapse recurrence after pregnancy and delivery remains similar to that after prolapse repair without subsequent pregnancies with few documented perinatal complications.

Abstract
IMPORTANCE The importance of this study is to explore potential differences in pathophysiologies of OAB-wet and OAB-dry. OBJECTIVES The aim of this study was to define fundamental and unique presenting features of patients exhibiting storage lower urinary tract symptoms (LUTS) with urgency incontinence (OAB-wet) and patients without urgency incontinence (OAB-dry). STUDY DESIGN This was a secondary analysis of cross-sectional data from the National Institutes of Health/National Institute of Diabetes and Digestive and Kidney Diseases-sponsored Symptoms of Lower Urinary Tract Dysfunction Research Network. Demographic, physical examination, and questionnaire responses were analyzed for women seeking care for LUTS at 6 U.S. centers. Differences between OAB-wet and OAB-dry patients were compared using the Fisher exact test and Mann-Whitney U test. Differences in questionnaire data were assessed using a Benjamini-Hochberg false discovery rate correction. RESULTS Fifty-six, 84, and 67 women were included in the OAB-dry, wet, and control cohorts, respectively. There was no difference in demographic and physical examination characteristics of the 2 groups. OAB-wet patients reported more urgency incontinence symptoms (LUTS 16a, P < 0.001). OAB-dry reported more bladder pain, feeling of incomplete bladder emptying (LUTS 4, P < 0.001), and a need to strain to urinate (AUA-SI 7, P = 0.003). Sensation of incomplete emptying and straining with urination did not correlate with elevated postvoid residual volumes. Although degrees of symptomatic bother were similar, bother in OAB-dry patients was most closely related to pelvic floor tenderness severity, whereas bother in OAB-wet patients was most related to urgency severity. CONCLUSIONS Women with OAB-dry have distinct presenting features of straining with urination, bladder pain, and a feeling of incomplete emptying. These suggest a unique pathophysiology driving OAB-dry symptoms, which we hypothesize is pelvic floor myofascial dysfunction.

Abstract
INTRODUCTION To understand the role of the urinary microbiome in disease states and interpret non-culture-based diagnostic urine testing of midstream urine specimens, we must have a better understanding of the urinary microbiome in asymptomatic, healthy individuals. We examined the impact of gender, age, and menopausal status on the healthy human urinary microbiome in asymptomatic control subjects enrolled in the multi-institution National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Multidisciplinary Approach to the Study of Chronic Pelvic Pain Network (MAPP) study. METHODS Asymptomatic, healthy controls, recruited to be ageand sex-matched to patients in the Trans-MAPP Epidemiology and Phenotyping Study, provided midstream urine collection for polymerase chain reaction (PCR)-electrospray ionization mass spectrometry identification of urinary microbiota. The microbiomes of male and female participants were described and analyzed for differences in composition and diversity at the species and genus level by sex, age, and, in females, by menopausal status. RESULTS Sixty-six total species were detected with a mean of 1.2 species (standard deviation [SD] 1.1) per male (n=97; mean age=43) and 2.3 (SD 1.3) per female (n=110, mean age=38) in asymptomatic, healthy controls. Species and genera diversity analyses showed significantly greater richness and diversity in females. With regard to species, Bifidobacterium subtile, Lactobacillus crispatus, and Lactobacillus johnsonii were more predominant in females. The genera Bifidobacterium, Staphylococcus, Lactobacillus, and Corynebacterium were more predominant in females, while for males the most prevalent organisms included Staphylococcus and Propionibacterium; only Propionibacterium approached a significant difference between genders. No significant difference in the presence and/or diversity of micro-organisms with menopausal status could be observed. Sex-specific age trends, particularly diversity, were larger for females than males. CONCLUSIONS These results suggest the urinary microbiome of healthy, asymptomatic subjects differed between genders and age in females, but not menopausal status. Gender differences may be attributable to the detection of urethral/vaginal organisms in females and prostate organisms in males. These findings will better allow us to interpret the results of microbiome reports in the midstream urine specimens of patients with urinary symptoms.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is defined as an unpleasant sensation perceived to be related to the bladder with associated urinary symptoms. Due to difficulties discriminating pelvic visceral sensation, IC/BPS likely represents multiple phenotypes with different etiologies that present with overlapping symptomatic manifestations, which complicates clinical management. We hypothesized that unique bladder pain phenotypes or "symptomatic clusters" would be identifiable using machine learning analysis (unsupervised clustering) of validated patient-reported urinary and pain measures. Patients (n = 145) with pelvic pain/discomfort perceived to originate in the bladder and lower urinary tract symptoms answered validated questionnaires [OAB Questionnaire (OAB-q), O'Leary-Sant Indices (ICSI/ICPI), female Genitourinary Pain Index (fGUPI), and Pelvic Floor Disability Index (PFDI)]. In comparison to asymptomatic controls (n = 69), machine learning revealed three bladder pain phenotypes with unique, salient features. The first group chiefly describes urinary frequency and pain with the voiding cycle, in which bladder filling causes pain relieved by bladder emptying. The second group has fluctuating pelvic discomfort and straining to void, urinary frequency and urgency without incontinence, and a sensation of incomplete emptying without urinary retention. Pain in the third group was not associated with voiding, instead being more constant and focused on the urethra and vagina. While not utilized as a feature for clustering, subjects in the second and third groups were significantly younger than subjects in the first group and controls without pain. These phenotypes defined more homogeneous patient subgroups which responded to different therapies on chart review. Current approaches to the management of heterogenous populations of bladder pain patients are often ineffective, discouraging both patients and providers. The granularity of individual phenotypes provided by unsupervised clustering approaches can be exploited to help objectively define more homogeneous patient subgroups. Better differentiation of unique phenotypes within the larger group of pelvic pain patients is needed to move toward improvements in care and a better understanding of the etiologies of these painful symptoms.

Abstract
OBJECTIVES To apply a human factors approach, the study of interactions between humans and complex systems, to investigate patient preparedness, satisfaction, and perceived usability with sacral neuromodulation (SNM) and develop interventions aimed at improving patient experience. MATERIALS AND METHODS Ten patients with overactive bladder undergoing staged SNM were observed, and data including pre-operative preparedness, satisfaction, perceived usability and barriers impacting patient experience were collected. Interventions were developed and an additional ten patients were observed. All patients were English-speaking and at least 18 years of age. RESULTS Pre-intervention patients had difficulty understanding the risks of the procedure, did not know what to expect post-operatively and were unsatisfied with pre-operative materials. Interventions included: A pre-procedure educational video and informational sheet, detailed discharge instructions; and a nursing inservice. Pre-operative preparedness (Stage I: U = 100, z = 3.785, P = .000; Stage II: U = 80, z = 2.864, P = .003), post-operative satisfaction (Stage I: U = 100, z = 3.788, P = .000; Stage II: U = 77.5, z = 2.665, P = .006.) and perceptions of usability (Stage I: U = 77.00, z = 2.056, P = .043.; Stage II: U = 80.50, z = 2.308, P = .019) increased significantly after the intervention. CONCLUSION Our observations highlight the value of implementing a human factors approach to identify and mitigate barriers impacting patient experiences with SNM. Through the implementation of systems-level interventions (ie, interventions that impact the non-clinical aspects of surgery such as patient and/or staff education), significant improvements can be made.

Comparison of deep phenotyping features of UCPPS with and without Hunner lesion: A MAPP-II Research Network Study. Neurourol Urodyn 2021; 40:810-818.

Abstract
OBJECTIVE To use the phenotyping data from the MAPP-II Symptom Patterns Study (SPS) to compare the systemic features between urologic chronic pelvic pain syndrome (UCPPS) with Hunner lesion (HL) versus those without HL. METHODS We performed chart review on 385 women and 193 men with UCPPS who enrolled in the MAPP-II SPS. 223 had cystoscopy and documentation of HL status. Among them, 12.5% had HL and 87.5% did not. RESULTS UCPPS participants with HL were older, had increased nocturia, higher Interstitial Cystitis Symptom and Problem Indexes, and were more likely to report "painful urgency" compared with those without HL. On the other hand, UCPPS without HL reported more intense nonurologic pain, greater distribution of pain outside the pelvis, greater numbers of comorbid chronic overlapping pain conditions, higher fibromyalgia-like symptoms, and greater pain centralization, and were more likely to have migraine headache than those with HL. UCPPS without HL also had higher anxiety, perceived stress, and pain catastrophizing than those with HL. There were no differences in sex distribution, UCPPS symptom duration, intensity of urologic pain, distribution of genital pain, pelvic floor tenderness on pelvic examination, quality of life, depression, pain characteristics (nociceptive pain vs. neuropathic pain), mechanical hypersensitivity in the suprapubic area during quantitative sensory testing, and 3-year longitudinal pain outcome and urinary outcome between the two groups. CONCLUSIONS UCPPS with HL displayed more bladder-centric symptom profiles, while UCPPS without HL displayed symptoms suggesting a more systemic pain syndrome. The MAPP-II SPS phenotyping data showed that Hunner lesion is a distinct phenotype from non-Hunner lesion.

Risk Factors for Intraoperative Bladder Perforation at the Time of Midurethral Sling Placement. Urology 2020; 148:100-105. [PMID: 33227306 DOI: 10.1016/j.urology.2020.11.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Revised: 11/05/2020] [Accepted: 11/11/2020] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To evaluate patient-specific and perioperative factors that may be predictive of bladder perforation during midurethral sling placement. METHODS A retrospective chart review of women who underwent a midurethral sling procedure at our institution between 2013 and 2017 was completed. All cases with bladder perforation were included. Patient demographics and perioperative factors were explored for associations with perforation. Bivariate analysis was used to compare baseline characteristics between those with and without perforation. Logistic regression modeling was used to identify predictors of perforation and associations between bladder perforation and postoperative sequelae. RESULTS Four hundred and ten women had a urethral sling procedure at our institution between 2013 and 2017. Of these, 35 (9%) had evidence of bladder perforation on cystoscopy. This rate was higher for retropubic slings (15%) compared to transobturator slings (2%). Those with a perforation were younger (54 vs 61 years, P= .004) and had a lower average BMI (24.1 kg/m2 vs 26.3 kg/m2, P = .022). Other risk factors included lack of pre-existing apical prolapse (11% vs 4%, P = .012) and concomitant urethrolysis (27% vs 8%, P = .024). In multivariable analysis, age, BMI, and sling type were significantly associated with perforation. In univariate analysis, perforation was associated with postoperative lower urinary tract symptoms (OR 2.3, P = .21) and urinary tract infection within 30 days of surgery (OR 2.2, P = .047). CONCLUSIONS Intraoperative bladder perforation was associated with younger patient age and lower BMI. Additionally, bladder perforation is a risk factor for postoperative urinary tract infection and lower urinary tract symptoms.

Abstract
OBJECTIVE To compare outcomes of patients who underwent robotic sacrocolpopexy (RSC) with and without concomitant mid-urethral sling (MUS) placement for prophylaxis or treatment of preoperative stress urinary incontinence (SUI) METHODS: We performed a retrospective review of all patients without prior incontinence procedures who underwent RSC with or without MUS placement by 3 surgeons (JA, LA, KE) at a single institution from 2012 to 2017 for treatment of pelvic organ prolapse. Patients had a MUS placed for either documented SUI or prophylaxis of SUI. We compared patient characteristics, operative details, postoperative outcomes, and complications between the groups. RESULTS A total of 134 patients were identified. 58 (43%) had a MUS placed for documented SUI, 43 (32%) had prophylactic MUS, and 33 (25%) did not have a MUS placed. There were no differences in baseline characteristics between the 3 groups. Patients who did not have a MUS placed had less estimated blood loss (76.4 vs 63.8 vs 36.9 mL, P = .018) but no difference in operative time (P = .408), length of stay (P = .427), or postoperative urinary retention (P = .988). A total of 4 (7%) patients who had a MUS placed for SUI had persistent SUI postoperatively. There were 2 (5%) patients who had a MUS placed prophylactically and 4 (12%) patients who did not have a MUS that developed de novo SUI. CONCLUSION In this series, we demonstrate the safety and efficacy of prophylactic MUS placement at the time of RSC. Randomized studies evaluating concomitant prophylactic sling at time of robotic sacrocolpopexy could further guide preoperative patient counseling and decision-making.

Abstract
AIMS Evaluation and treatment of functional conditions of the lower urinary tract (fcLUT), a subset of benign urinary tract conditions, is highly subjective due to overlapping symptomatology. Despite high prevalence and socioeconomic cost, there has been little improvement in their treatment and lack of progress in understanding their pathophysiology. This study investigates trends in quantity, monetary amounts, and awardees' characteristics of federally funded research awards for fcLUT compared to nonurologic benign conditions (NUBCs) and urologic malignancies. METHODS Data were extracted from the National Institutes of Health (NIH) and federal RePORTER databases in December 2019. We identified currently active awards in fcLUT, NUBC, and malignant urologic conditions and the associated demographic features of awardees. The authors also examined temporal funding trends for such awards. RESULTS These database searches revealed that there are consistently fewer awards and funding dollars for the study of fcLUT compared to other benign conditions with similar prevalences. While most research topics have received increased funding in awards and overall funding dollars over time, fcLUT funding has remained relatively flat. Urologists are also underrepresented; only 11 of the 86 recipients of NIH R01 awards to study fcLUT have clinical training in urology. CONCLUSIONS Even when compared to NUBC, funding for the study of fcLUT remains low and has stagnated over time. Further, investigators who are clinicians in the field of urology are in the minority of those doing this study. Given the need for clinical perspectives in fcLUT research, the lack of urologist representation will inhibit discovery and translational advances.

Abstract
AIMS Females are becoming surgeons at ever-increasing rates and doing so while many have or wish to have children. This study follows up on a 2007 effort to study the problems and conditions such women faced. We ask here if these challenges are different after a decade that included changes in working rules. METHODS A survey was sent to all female American Board of Urology diplomates. Birth trends, pregnancy complications, infertility service requirements, and satisfaction were evaluated in respondents (n = 183) and compared to the previous survey of female urologists who completed residency before August 2007 as well as Center for Disease Control data. RESULTS Seventy-six physicians completed the survey who were residents before 2007, while 107 replied who experienced residency after. The first group's average age was 50.2 and the second's 38.3. Overall, these women gave birth 6 to 7 years later than the US mean. Complications did not decrease, infertility occurred at similar levels, and both were higher than US norms. Length of maternity leave correlated with respondents' level of overall satisfaction. The most positive responses came from those with more than 8 weeks off (P = .002). CONCLUSIONS Women practicing in urology gave birth later, had greater fertility issues, used assisted reproductive technology (ART) more and reported a higher level of at least one complication during pregnancy than American women overall. Changes in hours and awareness of this issue have not made giving birth a healthier event for these physicians. Further investigation into factors other than work hours is needed.

Abstract
OBJECTIVES To use a human factors approach to conduct a needs assessment of patient preparedness, education, device usability, and satisfaction regarding all stages of sacral neuromodulation therapy and identify opportunities for improvement. Sacral neuromodulation, though minimally invasive, involves an initial testing phase that requires active patient participation. This process is relatively complex and, if a patient does not receive adequate preprocedure education, can be difficult to conceptualize. MATERIALS AND METHODS Candidates were recruited to participate before undergoing staged sacral neuromodulation. Ten patients were observed, and their experiences were evaluated at 4 phases: (1) date of test implant (Stage I), (2) 5 days following Stage I, (3) date of permanent implant (Stage II), and (4) 3 months following Stage II. Administered questionnaires focused on preoperative preparedness, postoperative satisfaction, and usability. RESULTS While every patient reported that their symptoms were at least "a little better" postoperatively, they generally had difficulty understanding the risks of the planned procedure, did not know what to expect postoperatively and were unsatisfied with the preoperative materials. Patients struggled with adjusting the settings for their implant devices and usability was considered "below average." Despite overall objective success, 30% of patients indicated that they would not recommend this treatment to friends/family. CONCLUSION This pilot needs analysis demonstrates several opportunities for improvement in the experience of patients undergoing sacral neuromodulation. These findings highlight the opportunities for a multifaceted intervention to improve patient understanding through the testing phase.

Considerations for Bedside Urologic Procedures in Patients With Severe Acute Respiratory Syndrome Coronavirus-2. Urology 2020; 142:26-28.

Abstract
Objective To provide guidance when performing bedside urologic procedures on severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) positive patients and offer considerations to maximize the safety of the patients and providers, conserve supplies, and provide optimal management of urologic issues. Methods Urologic trainees and attending physicians at our institution, who are familiar with existing safety recommendations and guidelines regarding the care of infected patients, were queried regarding their experiences to determine an expert consensus on best practices for bedside procedures for SARS-CoV-2 positive patients. Results Our team developed the following general recommendations for urologic interventions on SARS-CoV-2 positive patients: maximize use of telehealth (even for inpatient consults), minimize in-room time, use personal protective equipment appropriately, enlist a colleague to assist, and acquire all supplies that may be needed and maintain them outside the room. Detailed recommendations were also developed for difficult urethral catheterization, bedside cystoscopy, incision and drainage of abscesses, and gross hematuria/clot irrigations. Conclusion As patients hospitalized with SARS-CoV-2 infection are predominantly men over 50 years old, there are significant urologic challenges common in this population that have emerged with this pandemic. While there is tremendous variation in how different regions have been affected, the demographics of SARS-CoV-2 mean that urologists will continue to have a unique role in helping to manage these patients. Here, we summarize recommendations for bedside urologic interventions specific to SARS-CoV-2 positive patients based on experiences from a large metropolitan hospital system. Regulations and requirements may differ on an institutional basis, so these guidelines are intended to augment specific local protocols.

Abstract
PURPOSE To correlate the presence of fungi with symptom flares, pain and urinary severity in a prospective, longitudinal study of women with IC/BPS enrolled in the MAPP Research Network. METHODS Flare status, pelvic pain, urinary severity, and midstream urine were collected at baseline, 6 and 12 months from female IC/BPS participants with at least one flare and age-matched participants with no reported flares. Multilocus PCR coupled with electrospray ionization/mass spectrometry was used for identification of fungal species and genus. Associations between "mycobiome" (species/genus presence, relative abundance, Shannon's/Chao1 diversity indices) and current flare status, pain, urinary severity were evaluated using generalized linear mixed models, permutational multivariate analysis of variance, Wilcoxon's rank-sum test. RESULTS The most specific analysis detected 13 fungal species from 8 genera in 504 urine samples from 202 females. A more sensitive analysis detected 43 genera. No overall differences were observed in fungal species/genus composition or diversity by flare status or pain severity. Longitudinal analyses suggested greater fungal diversity (Chao1 Mean Ratio 3.8, 95% CI 1.3-11.2, p = 0.02) and a significantly greater likelihood of detecting any fungal species (OR = 5.26, 95% CI 1.1-25.8, p = 0.04) in high vs low urinary severity participants. Individual taxa analysis showed a trend toward increased presence and relative abundance of Candida (OR = 6.63, 95% CI 0.8-58.5, p = 0.088) and Malassezia (only identified in 'high' urinary severity phenotype) for high vs low urinary symptoms. CONCLUSION This analysis suggests the possibility that greater urinary symptom severity is associated with the urinary mycobiome urine in some females with IC/BPS.

Abstract
Purpose of Review The article discusses (1) techniques used to study bacterial urinary microbiota; (2) existence of non-bacterial urinary microbiota; (3) associations between changes in urinary microbiota and various benign lower urinary tract disorders. Recent Findings Urine harbors a diverse microbial community that resides within it. A multitude of studies have identified differences in these communities associated with urologic conditions, suggesting that microbial communities may maintain normal bladder homeostasis. Technological advances in analytic approaches have improved our understanding of the urinary microbiome. The choice of urine sampling method (voided, catheterized, or aspirated) will significantly influence microbiome findings. Sex and age highly influence urinary microbiota; in addition to rigorous inclusion criteria, microbial studies must be sufficiently powered to overcome the substantial interindividual variability of urinary microbiota. Regardless of these complicating factors, studies have identified microbial patterns correlating with both urologic diagnoses and treatment responses. Summary Without a clear understanding of the variability of and exogenous influences on the urinary microbiota in the absence of disease, it has been challenging to reveal the microbial patterns responsible for disease pathophysiology. Host mechanisms in response to the urinary microbiome are also poorly understood. Additional research can address whether the manipulation of urinary microbiota will benefit lower urinary tract health.

Abstract
INTRODUCTION Recent data suggest the urinary tract hosts a microbial community of varying composition, even in the absence of infection. Culture-independent methodologies, such as next-generation sequencing of conserved ribosomal DNA sequences, provide an expansive look at these communities, identifying both common commensals and fastidious organisms. A fundamental challenge has been the isolation of DNA representative of the entire resident microbial community, including fungi. MATERIALS AND METHODS We evaluated multiple modifications of commonly-used DNA extraction procedures using standardized male and female urine samples, comparing resulting overall, fungal and bacterial DNA yields by quantitative PCR. After identifying protocol modifications that increased DNA yields (lyticase/lysozyme digestion, bead beating, boil/freeze cycles, proteinase K treatment, and carrier DNA use), all modifications were combined for systematic confirmation of optimal protocol conditions. This optimized protocol was tested against commercially available methodologies to compare overall and microbial DNA yields, community representation and diversity by next-generation sequencing (NGS). RESULTS Overall and fungal-specific DNA yields from standardized urine samples demonstrated that microbial abundances differed significantly among the eight methods used. Methodologies that included multiple disruption steps, including enzymatic, mechanical, and thermal disruption and proteinase digestion, particularly in combination with small volume processing and pooling steps, provided more comprehensive representation of the range of bacterial and fungal species. Concentration of larger volume urine specimens at low speed centrifugation proved highly effective, increasing resulting DNA levels and providing greater microbial representation and diversity. CONCLUSIONS Alterations in the methodology of urine storage, preparation, and DNA processing improve microbial community profiling using culture-independent sequencing methods. Our optimized protocol for DNA extraction from urine samples provided improved fungal community representation. Use of this technique resulted in equivalent representation of the bacterial populations as well, making this a useful technique for the concurrent evaluation of bacterial and fungal populations by NGS.

Abstract
OBJECTIVES To address challenges in the diagnosis and classification of storage lower urinary tract symptoms (LUTS), we sought to define the fundamental features of overactive bladder (OAB) and interstitial cystitis/bladder pain syndrome (IC/BPS), two conditions with considerable symptomatic overlap. Through retrospective comparison of self-reported symptoms in women with a range of clinical presentations and symptom severities, we have attempted to refine the diagnostic features of OAB and IC/BPS and to develop a novel clinical nomogram to improve patient screening and classification. MATERIALS AND METHODS We performed a univariate analysis comparing responses to the female Genitourinary Pain Index (fGUPI), the OAB Questionnaire and O'Leary-Sant Indices (the Interstitial Cystitis Symptom Index and Interstitial Cystitis Problem Index) in an initial cohort of 50 patients with OAB, patients with IC/BPS and control subjects. Only eight questions differed significantly between the IC/BPS and OAB groups; we used five unique questions and three measuring bother to generate a novel composite scoring system and nomogram that included urgency incontinence, bladder pain and symptomatic bother domains to differentiate these populations, which was validated in a second cohort of 150 patients. The addition of a self-reported bother index resulted in the creation of a diagnostic algorithm to identify and classify LUTS clusters across the total population. RESULTS While all validated questionnaires could distinguish between controls and patients with storage LUTS, no combined symptom scores differed significantly between the IC/BPS and OAB groups. These results are reflective of the prevalence of significant bladder pain (35%) in patients with OAB and the presence of urge incontinence (25%) in patients with IC/BPS. Only the fGUPI pain domain scores differed between patients in the OAB and IC/BPS groups, but it was not accurate enough for diagnostic evaluation (68% accuracy). Our composite scores and nomogram gave a much-improved diagnostic accuracy (94%) and demonstrated utility as a screening tool to identify storage LUTS in patients presenting for unrelated complaints, e.g. microhaematuria. CONCLUSIONS There is significant overlap of urinary tract symptoms between OAB and IC/BPS. We present a novel algorithm that provides a binary output capable of guiding clinical diagnosis. Future studies aimed at assessing the diagnostic value of novel classification schemes that address symptoms rather than specific diagnoses may improve patient prognosis.

The Risk of Recurrent Urinary Incontinence Requiring Surgery After Suburethral Sling Removal for Mesh Complications. Urology 2017; 106:203-209.

Abstract
OBJECTIVE We sought to examine the risk of recurrent stress urinary incontinence (SUI) after suburethral sling mesh removal or excision. MATERIALS AND METHODS We conducted a retrospective cohort study of patients who were continent before removal or excision of synthetic midurethral slings; this cohort of 278 subjects was much larger than seen in previous such studies. Patients with preoperative incontinence, additional vaginal mesh placements, prior mesh revision/excision, existing SUI, and prior pelvic radiation or fistula were excluded. Only patients with follow-up detailing continence status within 1 year of mesh removal were examined. RESULTS Of 278 patients, 117 (70 retropubic and 47 transobturator) midurethral sling removals met inclusion criteria. Demographic data were comparable between groups. Presenting symptoms were also similar, with similar extrusion rates. Chronic pain was the reason for mesh removal in 80% of cases. In 1 year of follow-up, 38.6% (27/70) retropubic and 34.0% (16/47) transobturator sling removals had SUI requiring an anti-incontinence procedure. Total sling mesh removal was performed in 51.4% of retropubic vaginal mesh and 51.1% of transobturator mesh cases. CONCLUSION In this continent population with sling complications, approximately 1/3 developed significant SUI within 1 year of mesh removal requiring anti-incontinence surgery, regardless of the amount or type of mesh removed. Total mesh removal did not increase SUI risk.

Abstract
The mycobiome, defined as the fungal microbiota within a host environment, is an important but understudied component of the human microbial ecosystem. New culture-independent approaches to determine microbial diversity, such as next-generation sequencing methods, have discovered specific, characteristic, commensal fungal populations present in different body sites. These studies have also identified diverse patterns in fungal communities associated with various diseases. While alterations in urinary bacterial communities have been noted in disease states, a comprehensive description of the urinary mycobiome has been lacking. Early evidence suggests the urinary mycobiome is a diverse community with high intraindividual variability. In other disease systems, the mycobiome is thought to interact with other biomes and the host to play a role in organ homeostasis and pathology; further study will be needed to elucidate the role fungi play in bladder health and disease.

The Glt1 glutamate receptor mediates the establishment and perpetuation of chronic visceral pain in an animal model of stress-induced bladder hyperalgesia.

Abstract
Psychological stress exacerbates interstitial cystitis/bladder pain syndrome (IC/BPS), a lower urinary tract pain disorder characterized by increased urinary frequency and bladder pain. Glutamate (Glu) is the primary excitatory neurotransmitter modulating nociceptive networks. Glt1, an astrocytic transporter responsible for Glu clearance, is critical in pain signaling termination. We sought to examine the role of Glt1 in stress-induced bladder hyperalgesia and urinary frequency. In a model of stress-induced bladder hyperalgesia with high construct validity to human IC/BPS, female Wistar-Kyoto (WKY) rats were subjected to 10-day water avoidance stress (WAS). Referred hyperalgesia and tactile allodynia were assessed after WAS with von Frey filaments. After behavioral testing, we assessed Glt1 expression in the spinal cord by immunoblotting. We also examined the influence of dihydrokainate (DHK) and ceftriaxone (CTX), which downregulate and upregulate Glt1, respectively, on pain development. Rats exposed to WAS demonstrated increased voiding frequency, increased colonic motility, anxiety-like behaviors, and enhanced visceral hyperalgesia and tactile allodynia. This behavioral phenotype correlated with decreases in spinal Glt1 expression. Exogenous Glt1 downregulation by DHK resulted in hyperalgesia similar to that following WAS. Exogenous Glt1 upregulation via intraperitoneal CTX injection inhibited the development of and reversed preexisting pain and voiding dysfunction induced by WAS. Repeated psychological stress results in voiding dysfunction and hyperalgesia that correlate with altered central nervous system glutamate processing. Manipulation of Glu handling altered the allodynia developing after psychological stress, implicating Glu neurotransmission in the pathophysiology of bladder hyperalgesia in the WAS model of IC/BPS.
