Antibiotic use, best practice statement adherence, and UTI rate for intradetrusor onabotulinumtoxin-A injection for overactive bladder: A multi-institutional collaboration from the SUFU Research Network (SURN).

INTRODUCTION: Onabotulinumtoxin A (BTX-A) is a well-established treatment for overactive bladder (OAB). The American Urological Association (AUA) 2008 Antibiotic Best Practice Statement (BPS) recommended trimethoprim-sulfamethoxazole or fluoroquinolone for cystoscopy with manipulation. The aim of the study was to evaluate concordance with antibiotic best practices at the time of BTX-A injection and urinary tract infection (UTI) rates based on antibiotic regimen. METHODS: Men and women undergoing first-time BTX-A injection for idiopathic OAB with 100 units in 2016, within the SUFU Research Network (SURN) multi-institutional retrospective database were included. Patients on suppressive antibiotics were excluded. The primary outcome was concordance of periprocedural antibiotic use with the AUA 2008 BPS antimicrobials of choice for "cystoscopy with manipulation." As a secondary outcome we compared the incidence of UTI among women within 30 days after BTX-A administration. Each outcome was further stratified by procedure setting (office vs. operating room; OR). RESULTS: Of the cohort of 216 subjects (175 women, 41 men) undergoing BTX-A, 24 different periprocedural antibiotic regimens were utilized, and 98 (45%) underwent BTX-A injections in the OR setting while 118 (55%) underwent BTX-A injection in the office. Antibiotics were given to 86% of patients in the OR versus 77% in office, and 8.3% of subjects received BPS concordant antibiotics in the OR versus 82% in office. UTI rates did not vary significantly among the 141 subjects who received antibiotics and had 30-day follow-up (8% BPS-concordant vs. 16% BPS-discordant, CI -2.4% to 19%, p = 0.13). A sensitivity analysis of UTI rates based on procedure setting (office vs. OR) did not demonstrate any difference in UTI rates (p = 0.14). CONCLUSIONS: This retrospective multi-institutional study demonstrates that antibiotic regimens and adherence to the 2008 AUA BPS were highly variable among providers with lower rates of BPS concordant antibiotic use in the OR setting. UTI rates at 30 days following BTX-A did not vary significantly based on concordance with the BPS or procedure setting.

Relationships Between Urinary and Nonurinary Symptoms in Treatment-Seeking Women in LURN.

IMPORTANCE: Physical health and psychological health represent modifiable factors in the causal pathway of lower urinary tract symptoms (LUTS). OBJECTIVES: Understand the relationship between physical and psychological factors and LUTS over time. STUDY DESIGN: Adult women enrolled in the Symptoms of Lower Urinary Tract Dysfunction Research Network observational cohort study completed the LUTS Tool and Pelvic Floor Distress Inventory, including urinary (Urinary Distress Inventory), prolapse (Pelvic Organ Prolapse Distress Inventory), and colorectal anal (Colorectal-Anal Distress Inventory) subscales at baseline, 3 months, and 12 months. Physical functioning, depression, and sleep disturbance were measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaires; relationships were assessed using multivariable linear mixed models. RESULTS: Of 545 women enrolled, 472 had follow-up. Median age was 57 years; 61% and 78% reported stress urinary incontinence and overactive bladder, respectively; and 81% reported obstructive symptoms. The PROMIS depression scores were positively associated with all urinary outcomes (range, 2.5- to 4.8-unit increase per 10-unit increase in depression score; P < 0.01 for all). Higher sleep disturbance scores were associated with higher urgency, obstruction, LUTS Total Severity, Urinary Distress Inventory, and Pelvic Floor Distress Inventory (1.9- to 3.4-point increase per 10-unit increase, all P < 0.02). Better physical functioning was associated with less severe urinary symptoms except stress urinary incontinence (2.3- to 5.2-point decrease per 10-unit increase, all P < 0.01). All symptoms decreased over time; however, no association was detected between baseline PROMIS scores and trajectories of LUTS over time. CONCLUSIONS: Nonurologic factors demonstrated small to medium cross-sectional associations with urinary symptom domains, but no significant association was detected with changes in LUTS. Further work is needed to determine whether interventions targeting nonurologic factors reduce LUTS in women.

Hospitalizations Among Adults With CKD in Public Renal Specialty Practices: A Retrospective Study From Queensland, Australia.

Rationale & Objective: Little is known about hospital admissions in nondialysis patients with chronic kidney disease (CKD) before death or starting kidney replacement therapy (KRT). Study Design: Retrospective observational cohort study. Setting & Participants: Hospitalizations among 7,201 patients with CKD from 10 public renal clinics in Queensland (QLD), enrolled in the CKD.QLD registry starting in May 2011, were followed for 25,496.34 person-years until they started receiving KRT or died, or until June 30, 2018. Predictors: Demographic and clinical characteristics of patients with CKD. Outcomes: Hospital admissions. Analytical Approach: We evaluated the association of demographic and clinical features with hospitalizations, length of hospital stay, and cost. Results: Approximately 81.5% of the patients were admitted at least once, with 42,283 admissions, costing Australian dollars (AUD) 231 million. The average number of admissions per person-year was 1.7, and the cost was AUD 9,060, 10 times and 2 times their Australian averages, respectively. Single (1-day) admissions constituted 59.2% of all the hospital episodes, led by neoplasms (largely chemotherapy), anemia, CKD-related conditions and eye conditions (largely cataract extractions), but only 14.8% of the total costs. Approximately 41% of admissions were >1-day admissions, constituting 85.2% of the total costs, with cardiovascular conditions, respiratory conditions, CKD-related conditions, and injuries, fractures, or poisoning being the dominant causes. Readmission within 30 days of discharge constituted >42% of the admissions and 46.8% costs. Admissions not directly related to CKD constituted 90% of the admissions and costs. More than 40% of the admissions and costs were through the emergency department. Approximately 19% of the hospitalized patients and 27% of the admissions did not have kidney disease mentioned as either principal or associate causes. Limitations: Variable follow-up times because of different dates of consent. Conclusions: The hospital burden of patients with CKD is mainly driven by complex multiday admissions and readmissions involving comorbid conditions, which may not be directly related to their CKD. Strategies to prevent these complex admissions and readmissions should minimize hospital costs and outcomes. Plain-Language Summary: We analyzed primary causes, types, and costs of hospitalizations among 7,201 patients with chronic kidney disease (CKD) from renal speciality clinics across Queensland, Australia, over an average follow-up of 3.54 years. The average annual cost per person was $9,060, and was the highest in those with more advanced CKD, higher age, and with diabetes. More than 85% of costs were driven by more complex hospitalizations with longer length of stay. Cardiovascular disease was the single largest contributor for hospitalizations, length of hospital stay, and total costs. Readmission within 30 days of discharge, particularly for the same disorder, and multiday admissions should be the main targets for mitigation of hospital costs in this population.

Destroyed bladders: Characterization of progressive inflammatory cystitis.

PURPOSE: We identified a subset of patients with noninfectious cystitis who develop refractory symptoms marked by diffuse inflammatory changes, reduced bladder capacity, and vesicoureteral reflux (VUR), termed here as "progressive inflammatory cystitis" (PIC). Our objective was to describe the phenotype, disease outcomes, and pathologic findings of PIC. MATERIAL AND METHODS: A single institution retrospective cohort study of patients with PIC. Patients with a history of pelvic radiation, urologic malignancy, or neurogenic bladder were excluded. We describe cohort characteristics and use bivariate analyses to compare subgroups. Kaplan-Meier methods estimate time to urinary diversion. RESULTS: From 2008 to 2020, 46 patients with PIC were identified. The median age of symptom onset was 63 years old (interquartile range [IQR]: 56, 70) and the most common presenting symptoms were urinary urgency/frequency (54%) and incontinence (48%). Urodynamics showed a median maximum bladder capacity of 80 mL (IQR: 34, 152), commonly with VUR (68%) and hydronephrosis (59%). Ultimately 36 patients (78%) underwent urinary diversion at a median of 4.5 years (IQR: 2, 6.5) after symptom onset. Significant pathologic findings include presence of ulceration (52%), acute and chronic inflammation (68%), including eosinophils (80%), lymphoid follicles (56%), and mast cells in both lamina and muscularis propria (76%). CONCLUSIONS: PIC is a newly defined entity characterized by significantly diminished bladder capacity, upper tract changes, and relatively quick progression to urinary diversion. Larger prospective cohort studies are required to further characterize this severe phenotype of chronic noninfectious cystitis, aid earlier diagnosis, and guide management decisions.

Strategies for intraoperative glucose management: a scoping review.

PURPOSE: Perioperative hyperglycemia is associated with adverse outcomes for patients with and without diabetes. Guidelines and published protocols for intraoperative glycemic management have substantial variation in their recommendations. We sought to characterize the current evidence-guiding intraoperative glycemic management in a scoping review. SOURCES: Our search strategy included MEDLINE (Ovid and EBSCO), PubMed, PubMed Central, EMBASE, CINAHL, Cochrane Library, SciVerse Scopus, and Web of Science and a gray literature search of Google, Google Scholar, hand searching of the reference lists of included articles, OAISter, institutional protocols, and ClinicalTrails.gov. PRINCIPAL FINDINGS: We identified 41 articles that met our inclusion criteria, 24 of which were original research studies. Outcomes and exposures were defined heterogeneously across studies, which limited comparison and synthesis. Investigators often created arbitrary and differing categories of glucose values rather than analyzing glucose as a continuous variable, which limited our ability to combine results from different studies. In addition, the study populations and surgery types also varied considerably, with few studies performed during day surgeries and specific surgical disciplines. Study populations often included more than one type of surgery, indication, and urgency that were expected to have varying physiologic and inflammatory responses. Combining low- and high-risk patients in the same study population may obscure the harms or benefits of intraoperative glycemic management for high-risk procedures or patients. CONCLUSION: Future studies examining intraoperative glycemic management should carefully consider the study population, surgical characteristics, and pre- and postoperative management of hyperglycemia.

RéSUMé: OBJECTIF: L'hyperglycémie périopératoire est associée à des effets indésirables chez les patients diabétiques et non diabétiques. Les lignes directrices et les protocoles publiés pour la prise en charge glycémique peropératoire présentent des variations substantielles dans leurs recommandations. Nous avons cherché à caractériser les données probantes actuelles guidant la prise en charge glycémique peropératoire dans une étude de portée. SOURCES: Notre stratégie de recherche a inclus les bases de données MEDLINE (Ovid et EBSCO), PubMed, PubMed Central, EMBASE, CINAHL, Cochrane Library, SciVerse Scopus et Web of Science, ainsi qu'une recherche documentaire grise sur Google, Google Scholar, la recherche manuelle des listes de référence des articles inclus, OAISter, les protocoles institutionnels et ClinicalTrials.gov. CONSTATATIONS PRINCIPALES: Nous avons identifié 41 articles qui répondaient à nos critères d'inclusion, dont 24 étaient des études de recherche originales. Les critères d'évaluation et les expositions étaient définis de manière hétérogène d'une étude à l'autre, ce qui a limité la comparaison et la synthèse. Les chercheurs ont souvent créé des catégories arbitraires et différentes de valeurs glycémiques plutôt que d'analyser la glycémie comme une variable continue, ce qui a limité notre capacité à combiner les résultats de différentes études. En outre, les populations étudiées et les types de chirurgie variaient également considérablement, avec peu d'études réalisées lors de chirurgies ambulatoires et dans certaines disciplines chirurgicales spécifiques. Les populations étudiées comprenaient souvent plus d'un type de chirurgie, d'indication et d'urgence, pour lesquelles des réponses physiologiques et inflammatoires variables étaient attendues. La combinaison de patients à faible et à haut risque dans la même population d'étude a pu masquer les inconvénients ou les avantages d'une prise en charge glycémique peropératoire pour les interventions ou les patients à haut risque. CONCLUSION: Les études futures portant sur la prise en charge glycémique peropératoire devraient examiner attentivement la population étudiée, les caractéristiques chirurgicales et la prise en charge pré- et postopératoire de l'hyperglycémie.

Factors influencing decisions about neurogenic bladder and bowel surgeries among veterans and civilians with spinal cord injury.

OBJECTIVE: This study investigated factors influencing surgical decision-making (DM) to treat neurogenic bladder and bowel (NBB) dysfunction for veterans and civilians with spinal cord injury (SCI) in the United States (US). DESIGN: Semi-structured interviews complemented by survey measures. SETTING: Community-dwelling participants who received treatment at a major Midwestern US medical system, a nearby Veterans Affairs (VA) facility, and other VA sites around the US. PARTICIPANTS: Eighteen participants with SCI who underwent surgeries; completed semi-structured interviews and survey measures. INTERVENTIONS: Not applicable. OUTCOMES MEASURES: Semi-structured interviews were coded to reflect factors, DM enactment, and outcomes, including surgery satisfaction and quality of life (QOL). Quantitative measures included COMRADE, Ways of Coping Questionnaire, Bladder and Bowel Treatment Inventory, PROMIS Global Health and Cognitive Abilities scales, and SCI-QOL Bladder and Bowel short form. RESULTS: Themes identified about factors influencing DM included: recurrent symptoms and complications; balancing dissatisfaction with NBB management against surgery risks; achieving independence and life style adjustments; participant's driven solutions; support and guidance and trust in doctors; and access and barriers to DM. DM enactment varied across surgeries and individuals, revealing no clear patterns. Most participants were satisfied with the surgery outcomes. Some differences in demographics were observed between veterans and civilians. CONCLUSIONS: We have attempted to illustrate the process of NBB DM as individuals move from factors to enactment to outcomes. Attending to the complexity of the DM process through careful listening and clear communication will allow clinicians to better assist patients in making surgical decisions about NBB management.

Natural history of lower urinary tract symptoms in treatment-seeking women with pelvic organ prolapse; the Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN).

BACKGROUND: The association of pelvic organ prolapse with overactive bladder and other lower urinary tract symptoms, and the natural history of those symptoms are not well characterized. Previous cross-sectional studies demonstrated conflicting relationships between prolapse and lower urinary tract symptoms. OBJECTIVE: This study primarily aimed to determine the baseline association between lower urinary tract symptoms and prolapse and to assess longitudinal differences in symptoms over 12 months in women with and without prolapse. Secondary aims were to explore associations between lower urinary tract symptoms and prolapse treatment. We hypothesized that: (1) prolapse is associated with the presence of lower urinary tract symptoms, (2) lower urinary tract symptoms are stable over time in patients with and without prolapse, and (3) prolapse treatment is associated with lower urinary tract symptom improvement. STUDY DESIGN: Women enrolled in the Symptoms of Lower Urinary Tract Dysfunction Research Network Observational Cohort Study with adequate 12-month follow-up data were included. Prolapse and lower urinary tract symptom treatment during follow-up was guided by standard of care. Outcome measures included the Lower Urinary Tract Symptoms Tool total severity score (in addition to overactive bladder, obstructive, and stress urinary incontinence subscales) and Urogenital Distress Inventory-6 Short Form. Prolapse (yes or no) was defined primarily when Pelvic Organ Prolapse Quantification System points Ba, C or Bp were >0 (beyond the hymen). Mixed-effects models with random effects for patient slopes and intercepts were fitted for each lower urinary tract symptom outcome and prolapse predictor, adjusted for other covariates. The study had >90% power to detect differences as small as 0.4 standard deviation for less prevalent group comparisons (eg, prolapse vs not). RESULTS: A total of 371 women were analyzed, including 313 (84%) with no prolapse and 58 (16%) with prolapse. Women with prolapse were older (64.6±8.8 vs 55.3±14.1 years; P<.001) and more likely to have prolapse surgery (28% vs 1%; P<.001) and pessary treatment (26% vs 4%; P<.001) during the study. Average baseline Lower Urinary Tract Symptoms Tool total severity scores were lower (fewer symptoms) for participants with prolapse compared with those without (38.9±14.0 vs 43.2±14.0; P=.036), but there were no differences in average scores between prolapse groups for other scales. For all urinary outcomes, average scores were significantly lower (improved) at 3 and 12 months compared with baseline (all P<.05). In mixed-effects models, there were no statistically significant interactions between pelvic organ prolapse measurement and visit and time-dependent prolapse treatment groups (P>.05 for all regression interaction coefficients). The Lower Urinary Tract Symptoms Tool obstructive severity score had a statistically significant positive association with Pelvic Organ Prolapse Quantification System Ba, Bp, and point of maximum vaginal descent. The Lower Urinary Tract Symptoms Tool total severity scale had a statistically significant negative association with Pelvic Organ Prolapse Quantification System Ba and point of maximum vaginal descent. No other associations between prolapse and lower urinary tract symptoms were significant (P>.05 for all regression coefficients). Symptom differences between prolapse groups were small: all regression coefficients (interpretable as additive percentage change in each score) were between -5 and 5 (standard deviation of outcomes ranged from 14.0-32.4). CONCLUSION: Among treatment-seeking women with urinary symptoms, obstructive symptoms were positively associated with prolapse, and overall lower urinary tract symptom severity was negatively associated with prolapse. Lower Urinary Tract Symptoms Tool scores improved over 12 months regardless of prolapse status, including in those with treated prolapse, untreated prolapse, and without prolapse.

The prevalence of Fabry disease in a statewide chronic kidney disease cohort - Outcomes of the aCQuiRE (Ckd.Qld fabRy Epidemiology) study.

BACKGROUND: Prevalence of Fabry disease amongst Chronic Kidney Disease (CKD) patients on haemodialysis has been shown to be approximately 0.2%. METHODS: We undertook a cross-sectional study employing a cascade screening strategy for Fabry Disease amongst 3000 adult, male and female patients affected by CKD stage 1-5D/T at public, specialty renal practices within participating Queensland Hospital and Health Services from October 2017 to August 2019. A multi-tiered FD screening strategy, utilising a combination of dried blood spot (DBS) enzymatic testing, and if low, then lyso-GB3 testing and DNA sequencing, was used. RESULTS: Mean (SD) age was 64.0 (15.8) years (n = 2992), and 57.9% were male. Eight participants withrew out of the 3000 who consented. Of 2992 screened, 6 (0.20%) received a diagnosis of FD, 2902 (96.99%) did not have FD, and 84 (2.81%) received inconclusive results. Of the patients diagnosed with FD, mean age was 48.5 years; 5 were male (0.29%) and 1 was female (0.08%); 4 were on kidney replacement therapy (2 dialysis and 2 transplant); 3 were new diagnoses. CONCLUSIONS: Estimated overall FD prevalence was 0.20%. Screening of the broader CKD population may be beneficial in identifying cases of FD. TRIAL REGISTRATION: The aCQuiRE Study has been prospectively registered with the Queensland Health Database of Research Activity (DORA, https://dora.health.qld.gov.au ) as pj09946 (Registered 3rd July 2017).

TERT Promoter Mutations in Keratinizing and Nonkeratinizing Squamous Metaplasia of the Urinary Tract.

We identified urothelial tract biopsy and resection specimens with keratinizing squamous metaplasia (KSM), nonkeratinizing squamous metaplasia (NKSM), and urothelial and squamous carcinomas over a 20-yr period, focusing on cases with neurogenic lower urinary tract dysfunction (NLUTD) and/or those with spatial or temporal variation in sampling. TERT promoter mutations as assessed via allele-specific polymerase chain reaction were surprisingly common in our testing cohort, identified not only in 15 (94%) invasive cancer foci but also in 13 (68%) examples of KSM and seven (70%) examples of NKSM. TERT promoter mutations were present in 23 foci from NLUTD specimens and 11 foci from bladder diverticula, including in foci of KSM, NKSM, and unremarkable urothelium from cases with no clinical association with previous, concurrent, or subsequent cancer. Our demonstration of temporally and spatially persistent TERT promoter mutation in examples of KSM and NKSM in cases of bladder cancer and in morphologically benign cases with neurogenic dysfunction suggests a molecular mechanism by which such pre-neoplastic lesions can potentially progress and develop into overt carcinoma. Given the interest in TERT promoter mutations as a potential biomarker for the development of bladder cancer, these findings possibly explain the association between conditions with chronic urinary bladder injury (such as the natural history of NLUTD) and higher risk of bladder cancer. TERT promoter mutations may represent an early event in bladder cancer tumorogenesis, and our findings expand on the clinical ramifications and predictive value of TERT promoter mutations in this context. PATIENT SUMMARY: Mutations in the TERT gene are the most common genetic changes in bladder cancer. We found that these mutations are also sometimes present in patients with chronic bladder irritation such as neurogenic bladder dysfunction and changes to the lining of the bladder that pathologists would consider "benign." This finding might explain why such conditions are associated with the development of bladder cancer.

Incomplete bladder emptying and urinary tract infections after botulinum toxin injection for overactive bladder: Multi-institutional collaboration from the SUFU research network.

INTRODUCTION: Onabotulinumtoxin A (BTX-A) is an effective therapy for overactive bladder (OAB), however, adverse events may prevent patients from initiating therapy. The study objective was to report real-world rates of incomplete emptying and urinary tract infection (UTI) in men and women undergoing BTX-A for OAB. METHODS: Eleven clinical sites performed a retrospective study of adults undergoing first-time BTX-A injection (100 units) for idiopathic OAB in 2016. Exclusions included: postvoid residual (PVR) > 150 ml, prior BTX-A, pelvic radiation, or need for preprocedure catheterization. Primary outcomes at 6 months were incomplete emptying (clean intermittent catheterization [CIC] or PVR ≥ 300 ml without the need for CIC); and UTI (symptoms with either positive culture or urinalysis or empiric treatment). We compared rates of incomplete emptying and UTI within and between sexes, using univariate and multivariable models. RESULTS: 278 patients (48 men and 230 women) met inclusion criteria. Mean age was 65.5 years (range: 24-95). 35% of men and 17% of women had incomplete emptying. Men had 2.4 (95% CI: 1.04-5.49) higher odds of incomplete emptying than women. 17% of men and 23.5% of women had ≥1 UTI, the majority of which occurred within the first month following injection. The strongest predictor of UTI was a history of prior UTI (OR: 4.2 [95% CI: 1.7-10.3]). CONCLUSIONS: In this multicenter retrospective study, rates of incomplete emptying and UTI were higher than many previously published studies. Men were at particular risk for incomplete emptying. Prior UTI was the primary risk factor for postprocedure UTI.

Kidney failure, CKD progression and mortality after nephrectomy.

PURPOSE: This study tested the hypothesis that progression of chronic kidney disease (CKD) is less aggressive in patients whose primary cause of CKD was nephrectomy, compared with non-surgical causes. METHODS: A sample of 5983 patients from five specialist nephrology practices was ascertained from the Queensland CKD Registry. Rates of kidney failure/death were compared on primary aetiology of CKD using multivariable Cox proportional hazards models. CKD progression was compared using multivariable linear and logistic regression analyses. RESULTS: Of 235 patients with an acquired single kidney as their primary cause of CKD, 24 (10%) and 38 (17%) developed kidney failure or died at median [IQR] follow-up times of 12.9 [2.5-31.0] and 33.6 [18.0-57.9] months after recruitment. Among patients with an eGFR < 45 mL/min per 1.73m2 at recruitment, patients with diabetic nephropathy and PCKD had the highest rates (per 1000 person-years) of kidney failure (107.8, 95% CI 71.0-163.8; 75.5, 95% CI 65.6-87.1); whereas, patients with glomerulonephritis and an acquired single kidney had lower rates (52.9, 95% CI 38.8-72.1; 34.6, 95% CI 20.5-58.4, respectively). Among patients with an eGFR ≥ 45 mL/min per 1.73m2, those with diabetic nephropathy had the highest rates of kidney failure (16.6, 95% CI 92.5-117.3); whereas, those with glomerulonephritis, PCKD and acquired single kidney had a lower risk (11.3, 95% CI 7.1-17.9; 11.7, 95% CI 3.8-36.2; 10.7, 95% CI 4.0-28.4, respectively). CONCLUSION: Patients who developed CKD after nephrectomy had similar rates of adverse events to most other causes of CKD, except for diabetic nephropathy which was consistently associated with worse outcomes. While CKD after nephrectomy is not the most aggressive cause of kidney disease, it is by no means benign, and is associated with a tangible risk of kidney failure and death, which is comparable to other major causes of CKD.

Changes in patient reported outcome measures after treatment for female urethral stricture.

INTRODUCTION: There is a paucity of patient reported outcome measure (PROM) data for women with urethral strictures. To address this gap, we aim to evaluate change in PROM among women who underwent surgery for a stricture. METHODS: American Urological Association Symptom Index (AUA-SI) and Urogenital Distress Inventory (UDI-6) data from a multi-institutional retrospective cohort study of women treated for urethral stricture was assessed. RESULTS: Fifty-seven women had either AUA-SS or UDI-6 and 26 had baseline and postoperative data for either. Most women underwent urethroplasty (77%) and the majority (73%) remained stricture free at median follow-up of 21 months (interquartile range [IQR] 7-37). The median baseline AUA-SI was 21 (IQR 12-28) and follow-up was 10 (IQR 5-24). After treatment, there was a median decrease of 12 (IQR -18 to -2) in AUA-SI (p = 0.003). The median AUA Quality of life (QOL) score at baseline and follow-up were 6 (IQR 4-6) and 3 (IQR 2-5), respectively. There was a median AUA-QOL improvement of 2 points (-5,0; p = 0.007) from a baseline 5 (unhappy) to 3 (mixed). Median UDI-6 scores were 50 (IQR 33-75) at baseline and 17 (IQR 0-39), at follow-up. After treatment, there was a median decrease of 19 (-31 to -11; p = 0.01). CONCLUSION: Women with urethral strictures have severe lower urinary tract symptoms which improved after surgery. This study substantiates the claims that recognizing and treating women with urethral stricture disease greatly improves lower urinary tract symptoms and QOL.

Depth and Location of Sacral Suture Placement During Cadaveric Simulation of Open Sacrocolpopexy.

OBJECTIVES: To evaluate the location and depth of placement of sacral sutures in a cadaveric sacrocolpopexy model. MATERIALS AND METHODS: Following a 1-hour instructional session, trainees performed an open sacrocolpopexy on unembalmed cadavers under guidance by a Female Pelvic Medicine & Reconstructive Surgery board-certified surgeon. At completion of the session, the presacral tissues were dissected and the location and depth of each sacral suture was identified. RESULTS: A total of 19 sutures were placed by 9 trainees into 8 cadavers. The majority of sutures (14/19, 74%) were placed between L5 and S1. Three sutures (16%) were placed at L5 and 2 (11%) were placed at the S1 vertebral body. The mean depth of the anterior longitudinal ligament (ALL) was 1.4 mm. When assessing depth of suture placement, 13 of 19 (68%) were placed into the ALL without penetrating the disc space. Two sutures (11%) were placed in the tissues superficial to the ALL and 4 (22%) were placed deep to the ALL into the periosteum or disc. CONCLUSION: This study of cadaveric simulation of open sacrocolpopexy finds that location of sacral suture placement is most commonly at the level of the L5-S1 disc space and that placement of sutures into the underlying disc occurs about 1 in 5 times.

Managing Interstitial Cystitis/Bladder Pain Syndrome in Older Adults.

In this review, the current literature regarding pharmacotherapy treatment strategies available for the management of interstitial cystitis/bladder pain syndrome in older adults is addressed. The focus is on those treatments described by the American Urologic Association guidelines, organized according to clinical phenotype. Symptoms at presentation can vary with age, with older adults being more likely to experience nocturia, urinary incontinence, and Hunner's lesions than their younger counterparts. As such, treatment of interstitial cystitis/bladder pain syndrome should follow an individualized multimodal plan based on the patient's unique phenotype(s), starting with the most conservative options and escalating as needed. The side-effect profile and medication interactions should be reviewed, especially when treating older adults, requesting the aid of pharmacists or the primary care physician as needed to safely provide treatment.

Treatment of urethral stricture disease in women: A multi-institutional collaborative project from the SUFU research network.

AIM: Female urethral stricture disease is rare and has several surgical approaches including endoscopic dilations (ENDO), urethroplasty with local vaginal tissue flap (ULT) or urethroplasty with free graft (UFG). This study aims to describe the contemporary management of female urethral stricture disease and to evaluate the outcomes of these three surgical approaches. METHODS: This is a multi-institutional, retrospective cohort study evaluating operative treatment for female urethral stricture. Surgeries were grouped into three categories: ENDO, ULT, and UFG. Time from surgery to stricture recurrence by surgery type was analyzed using a Kaplan-Meier time to event analysis. To adjust for confounders, a Cox proportional hazard model was fit for time to stricture recurrence. RESULTS: Two-hundred and ten patients met the inclusion criteria across 23 sites. Overall, 64% (n = 115/180) of women remained recurrence free at median follow-up of 14.6 months (IQR, 3-37). In unadjusted analysis, recurrence-free rates differed between surgery categories with 68% ENDO, 77% UFG and 83% ULT patients being recurrence free at 12 months. In the Cox model, recurrence rates also differed between surgery categories; women undergoing ULT and UFG having had 66% and 49% less risk of recurrence, respectively, compared to those undergoing ENDO. When comparing ULT to UFG directly, there was no significant difference of recurrence. CONCLUSION: This retrospective multi-institutional study of female urethral stricture demonstrates that patients undergoing endoscopic management have a higher risk of recurrence compared to those undergoing either urethroplasty with local flap or free graft.

The Ckd. Qld fabRy Epidemiology (aCQuiRE) study protocol: identifying the prevalence of Fabry disease amongst patients with kidney disease in Queensland, Australia.

BACKGROUND: Fabry disease (FD) is a rare, lysosomal storage disorder caused by the absence or deficiency of the enzyme alpha-galactosidase A (α-Gal A) that leads to the abnormal accumulation of the lipid globotriaosylceramide (GB3) in a variety of cell types and tissues throughout the body. FD has an x-linked inheritance pattern. Previously thought to be only carriers, females can also experience FD symptomatology. Symptoms vary in type and severity from patient to patient and tend to increase in severity with age. FD symptoms are non-specific and may be shared with those of other diseases. Misdiagnoses and diagnostic delays are common, often resulting in progressive, irreversible tissue damage. The estimated prevalence of FD in the general population is 1:40,000 to 1:117,000 individuals. However, it is estimated that the prevalence of FD in the dialysis population is 0.12 to 0.7%. Little is known about the prevalence of FD in the broader Chronic Kidney Disease (CKD) population. METHODS: This is an epidemiological study of the prevalence of FD in CKD patents identified from the public renal speciality practices in Queensland, Australia. A cascade approach to screening is being employed with dried blood spot testing for blood levels of alpha-galactosidase A (Alpha-Gal), with follow-up testing for patients with abnormal results by plasma levels of globotriaosylsphingosine (Lyso-GB3) for females and non-definitive cases in males. A diagnosis of FD is confirmed through genetic testing of the GLA gene in cases suspected of having FD based upon Alpha-Gal and Lyso-GB3 testing. DISCUSSION: Expected outcomes of this study include more information about the prevalence of FD at all stages of CKD, including for both males and females. The study may also provide information about common characteristics of FD to assist with diagnosis and optimal management/treatment. Screening is also available for family members of diagnosed patients, with potential for early diagnosis of FD and intervention for those individuals.

Reconsideration of pelvic floor muscle training to prevent and treat incontinence after radical prostatectomy.

Urinary incontinence is common after radical prostatectomy. Pelvic floor muscle training provides a plausible solution. Although early trials provided promising results, systematic reviews have questioned the efficacy of this intervention. A major consideration is that most clinical trials in men have applied principles developed for pelvic floor muscle training for stress urinary incontinence in women, despite differences in anatomy between sexes and differences in the mechanisms for continence/incontinence. Literature regarding continence control in men has been conflicting and often based on erroneous anatomy. New understanding of continence mechanisms in men, including the complex contribution of multiple layers of striated pelvic floor muscles, and detailed consideration of the impact of radical prostatectomy on continence anatomy and physiology, have provided foundations for a new approach to pelvic floor muscle training to prevent and treat incontinence after prostatectomy. An approach to training can be designed to target the pathophysiology of incontinence. This approach relies on principles of motor learning and exercise physiology, in a manner that is tailored to the individual patient. The aims of this review are to consider new understanding of continence control in men, the mechanisms for incontinence after radical prostatectomy, and to review the characteristics of a pelvic floor muscle training program designed to specifically target recovery of continence after prostatectomy.

Advanced Management of Patients With Ulcerative Interstitial Cystitis/Bladder Pain Syndrome.

OBJECTIVE: To describe a stepwise management of patients with interstitial cystitis/bladder pain syndrome (IC/BPS) with Hunner's lesions and present single institution long-term outcomes. METHODS: This is a retrospective review of a single tertiary center experience with management of patients with Hunner's lesions from January 2005 to January of 2015. Patients who met the diagnostic criteria for IC/BPS were included. Systematic approach to treatment of patients with Hunner's lesions is proposed based on our results. RESULTS: Fifty-five patients with IC/BPS and Hunner's lesions were included. Mean age was 65.0 ±12.7 years, 76.4% (42/55) were female, and median symptom duration was 2 years (interquartile range [IQR] 1.7). All patients had a biopsy to rule out malignancy with therapeutic fulguration which resulted in subjective symptom improvement in 81.8% (45/55) and median time to repeat procedures was 12 months (IQR 621). Triamcinolone injection into the lesion was done in 35 patients and 91.4% (32/35) reported subjective improvement. Repeat injections were done for 74% (26/35) and median time between injections was 8 months (IQR 4, 13). AUA symptom scores and quality of life improved significantly with both treatment modalities. Adjunctive treatment with cyclosporine was used in 47.2% (26/55), and 7.2% (4/55) went on to have a cystectomy. CONCLUSION: Patients with Hunner's lesions benefit from early progression from conservative treatments to endoscopic management. Excellent symptom control can be achieved with biopsy/fulguration and triamcinolone injections but recurrence is common and repeat treatments are needed for most patients.
