Abstract
Overactive bladder (OAB) is a common debilitating bladder condition with unknown etiology and limited diagnostic modalities. Here, we explored a novel high-throughput and unbiased multiplex approach with cellular and molecular components in a well-characterized patient cohort to identify biomarkers that could be reliably used to distinguish OAB from controls or provide insights into underlying etiology. As a secondary analysis, we determined whether this method could discriminate between OAB and other chronic bladder conditions. We analyzed plasma samples from healthy volunteers (n = 19) and patients diagnosed with OAB, interstitial cystitis/bladder pain syndrome (IC/BPS), or urinary tract infections (UTI; n = 51) for proinflammatory, chemokine, cytokine, angiogenesis, and vascular injury factors using Meso Scale Discovery (MSD) analysis and urinary cytological analysis. Wilcoxon rank-sum tests were used to perform univariate and multivariate comparisons between patient groups (controls, OAB, IC/BPS, and UTI). Multivariate logistic regression models were fit for each MSD analyte on 1) OAB patients and controls, 2) OAB and IC/BPS patients, and 3) OAB and UTI patients. Age, race, and sex were included as independent variables in all multivariate analysis. Receiver operating characteristic (ROC) curves were generated to determine the diagnostic potential of a given analyte. Our findings demonstrate that five analytes, i.e., interleukin 4, TNF-α, macrophage inflammatory protein-1β, serum amyloid A, and Tie2 can reliably differentiate OAB relative to controls and can be used to distinguish OAB from the other conditions. Together, our pilot study suggests a molecular imbalance in inflammatory proteins may contribute to OAB pathogenesis.

Abstract
PURPOSE We compare the systemic (nonurological) symptoms between patients with overactive bladder and subjects without overactive bladder. We also compare the urinary symptoms, quality of life and psychosocial measures between the 2 subgroups of patients with overactive bladder with a high vs low systemic symptom burden. MATERIALS AND METHODS Patients diagnosed with overactive bladder (51) and age matched individuals without overactive bladder (30) were administered the polysymptomatic, polysyndromic questionnaire to assess the numbers and distribution of systemic symptoms across multiple organ systems. Validated instruments were administered to evaluate urinary symptoms (ICIQ-UI, ICIQ-OAB, OAB-q, USS), quality of life (UDI-6, IIQ-7, OAB-q) and psychosocial difficulties (depression, anxiety, stress, sexual trauma, sleep, fatigue). Patients with overactive bladder were divided into 2 subgroups (with and without widespread systemic symptoms) and their responses were compared. RESULTS Patients with overactive bladder reported significantly more systemic (nonurological) symptoms compared to controls (mean ± SD 17.5 ± 12.3 vs 6.4 ± 7.9 symptoms, p <0.001). Differences were observed across multiple organ systems (neurologic, cardiopulmonary, gastrointestinal, sexual, musculoskeletal and gynecologic, p <0.05). About a third of patients with overactive bladder (31.4%) reported widespread systemic symptoms across multiple organ systems (mean 32.0 symptoms). The presence of widespread systemic symptoms among patients with overactive bladder was correlated with worse incontinence/overactive bladder symptoms (ICIQ-UI, OAB-q), poorer quality of life (UDI-6, IIQ-7, OAB-q) and more psychosocial difficulties (depression, anxiety, fatigue and higher stress, p <0.05). CONCLUSIONS The increased presence of nonurological symptoms in overactive bladder suggests an underlying systemic etiology and pathogenetic mechanisms that may contribute to overactive bladder. This study highlights the importance of understanding systemic factors in urological conditions otherwise thought to be organ specific.

Abstract
OBJECTIVES To evaluate the changes in use of the different imaging modalities for diagnosing upper tract urothelial carcinoma (UTUC) and assess how these changes have affected tumor stage at the time of surgery. MATERIALS AND METHODS We assessed the Surveillance, Epidemiology, and End Results (SEER) cancer registry and linked Medicare claims data (1992-2009) for 5377 patients who underwent surgery for UTUC. We utilized International Classification of Disease-Oncology 3 codes to identify UTUC. International Classification of Disease, ninth Revision, Clinical Modification and Current Procedure Terminology codes identified surgical treatment and imaging modalities. We assessed for use of intravenous pyelography, retrograde pyelography (RGP), computed tomography urography (CTU), magnetic resonance urography (MRU), and endoscopy. For each modality, patients were categorized as having received the modality at least once or not at all. Patient characteristics were compared using chi-squared tests. Usage of imaging modalities and tumor stage was trended using Cochran-Armitage tests. We stratified our data into 2 multivariate logistic regression models to determine the effect of imaging modalities on tumor stage: 1992 to 1999 with all modalities except MRU, and 2000 to 2009 with all modalities. RESULTS Our patient population was predominantly White males of more than 70 years old. Intravenous pyelography and RGP declined in use (62% and 72% in 1992 vs. 6% and 58% in 2009, respectively) while computed tomography urography, MRU, and endoscopy increased in use (2%, 0%, and 37% in 1992 vs. 44%, 6%, and 66% in 2009, respectively). In both regression analyses, endoscopy was associated with lower-stage tumors. In the 2000 to 2009 model, RGP was associated with lower-stage tumors, and MRU was associated with higher-stage tumors. Finally, our data showed an increasing number of modalities utilized for each patient (1% receiving 4 modalities in 1992 vs. 20% in 2009). CONCLUSIONS We found trends toward the utilization of newer imaging modalities to diagnose UTUC and more modalities per patient. Endoscopy and RGP were associated with smaller tumors, whereas MRU was associated with larger tumors. Further studies are needed to evaluate the utility of the different modalities in diagnosing UTUC.

Abstract
OBJECTIVE To assess the impact of surgery for benign prostatic hyperplasia (BPH) on use of medication (5-alpha reductase inhibitors, alpha blockers, antispasmodics), we assessed preoperative and postoperative medication utilization among surgically treated men. PATIENTS AND METHODS Using the Truven Health Analytics MarketScan Commercial Claims Database, we defined a cohort of men aged <65 years who had surgical therapy for BPH with either transurethral resection of the prostate (TURP) or laser procedures from 2007 through 2009. Primary outcomes included freedom from medical or surgical intervention by 4 months after surgery (chi-square and multivariable logistic regression) and subsequent use of medical or surgical intervention in initial responders (Kaplan-Meier and multivariable Cox regression). RESULTS We identified 6430 patients treated with either TURP (3096) or laser procedure (3334) for BPH. Presurgical antispasmodic use was associated with the highest risk of medication use at 4 months after surgery (odds ratio, 5.19; 95% confidence interval (CI), 3.16-8.53 vs no medication use before surgery). At 3 years after surgery, 6% (95% CI, 4%-8%) of laser-treated and 4% (95% CI, 2%-5%) of TURP-treated patients had repeat surgical intervention, and both laser- and TURP-treated patients had an estimated new use of medication rate of 22% (95% CI, 18%-25% laser and 20%-25% TURP). The strongest predictor of intervention after surgery was preoperative antispasmodic use (hazard ratio, 2.49; 95% CI, 1.41-4.43). CONCLUSION Our results show a need for effective patient counseling about continued or new use of medical therapy after laser and TURP procedures. However, most patients experience durable improvement after surgical intervention for BPH.

Abstract
AIMS (1) To describe the Prevalence of childhood and recent trauma in patients with overactive bladder (OAB), and (2) assess the impact of traumatic events on the clinical presentation and the severity of OAB symptoms, quality of life, and psychosocial health. METHODS Patients diagnosed with OAB (n = 51) and age-matched healthy controls (n = 30) were administered the Childhood Traumatic Events Scale and Recent Traumatic Events Scale, assessing exposure and perceived impact of common traumatic events. Among OAB patients, validated instruments were administered to correlate traumatic exposure to evaluate adult urinary symptoms (ICIQ-UI, ICIQ-OAB, OAB-q, UDI-6, IIQ-7, USS), mood dysregulation (HADS), sleep and fatigue (PROMIS), and Psychological stress (PSS). RESULTS Childhood sexual trauma was more prevalent in patients with OAB compared to controls (29.4% vs. 6.7%, P = 0.041). OAB patients also rated their childhood sexual exposure as more traumatic compared to controls (mean ratings of 1.7 vs. 0.4, P = 0.050). There was no difference in childhood deaths (P = 0.24), parental upheaval (P = 0.87), violence (P = 0.099), illness/injury (P = 0.683), or any recent traumatic events between OAB and control subjects. Childhood trauma predicted worse bladder pain (P = 0.005), worse non-urologic pain (P = 0.017), poorer mood (P = 0.001), higher anxiety (P = 0.029), higher physical symptom burden (P < 0.001), and higher psychological stress (P < 0.039). However, childhood trauma did not correlate with the severity of OAB symptoms (urgency, frequency, incontinence). CONCLUSIONS Thirty percent of OAB patients reported childhood sexual trauma. These patients report more pain symptoms, poorer mood, and greater somatic burden. These data highlight the potentiating role of psychosocial stressors from childhood in the adult suffering from OAB.

Abstract
BACKGROUND Follow-up care after radical cystectomy is poorly defined, with extensive variation in practice patterns. We sought to determine sources of these variations in care as well as examine the economic effect of standardization of care to guideline-recommended care. METHODS Using linked Surveillance, Epidemiology, and End Results (SEER)-Medicare data from 1992 to 2007, we determined follow-up care expenditures (time and geography standardized) for 24 months after surgery. Accounted expenditures included office visits, imaging studies, urine tests, and blood work. A multilevel model was implemented to determine the effect of region, surgeon, and patient factors on care delivery. We then compared the actual expenditures on care in the Medicare system (interquartile range) with the expenditures if patients received care recommended by current clinical guidelines. RESULTS Expenditures over 24 months of follow-up were calculated per month and per patient. The mean and median total expenditures per patient were $1108 and $805 respectively (minimum $0, maximum $9,805; 25th-75th percentile $344-$1503). Variations in expenditures were most explained at the patient level. After accounting for surgeon and patient levels, we found no regional-level variations in care. Adherence to guidelines would lead to an increase in expenditures by 0.80 to 10.6 times the expenditures exist in current practice. CONCLUSION Although some regional-level and surgeon-level variations in care were found, the most variation in expenditure on follow-up care was at the patient level, largely based on node positivity, chemotherapy status, and final cancer stage. Standardization of care to current established guidelines would create higher expenditures on follow-up care than current practice patterns.

Abstract
Background The relationship between psychological stress and interstitial cystitis/bladder pain syndrome (IC/BPS) has been well described. Even though there is some overlapping of symptoms between overactive bladder (OAB) and IC/BPS, there have been very few studies that specifically investigated the relationship between psychological stress and urinary symptoms in OAB patients who do not have pelvic pain. Here we examined the relationship between psychological stress levels and the severity of overactive bladder (OAB) symptoms. Methods Patients diagnosed with OAB (n=51), IC/BPS (n=27), and age-matched healthy controls (n=30) participated in a case control study that inquired about their psychological stress levels using the perceived stress scale (PSS). PSS reported by the three patient groups were compared. Among OAB patients, their responses on the PSS was correlated to OAB symptoms using the following questionnaires: 1) international consultation on incontinence – urinary incontinence (ICIQ-UI), 2) international consultation on incontinence – overactive bladder (ICIQ-OAB), 3) OAB-q short form, 4) urogenital distress inventory (UDI-6), 5) incontinence impact questionnaire (IIQ-7), 6) urgency severity scale (USS), 7) numeric rating scales of urgency symptom, and 8) frequency symptom. Spearman’s correlation tests were performed to examine the relationship between psychological stress levels and the severity of OAB symptoms. Results OAB patients reported psychological stress levels that were as high as IC/BPS patients (median 17.0 versus 18.0, p=0.818, Wilcoxon sum rank test), and significantly higher than healthy controls (17.0, versus 7.5, p=0.001). Among OAB patients, there was a positive correlation between perceived stress levels and urinary incontinence symptoms (ICIQ-UI, Spearman’s correlation coefficient=0.39, p=0.007), and impacts on quality of life (UDI-6, IIQ-7, OAB-q quality of life subscale; Spearman’s correlation coefficient=0.32, 0.31, 0.39, and p=0.028, 0.005, 0.029, respectively). No significant correlation was observed between perceived stress levels and urgency or frequency symptoms (ICIQ-OAB, USS, numeric ratings of urgency and frequency). Conclusions OAB patients reported psychological stress levels that were as high as IC/BPS patients, and significantly higher than healthy controls. There was a positive correlation between perceived stress levels and urinary incontinence symptoms, and its impacts on quality of life among OAB patients.

Abstract
47 Background: National Comprehensive Cancer Network (NCCN) category 1 recommendation for localized high risk prostate cancer (HR-PCa) is definitive radiation therapy (RT) and androgen deprivation therapy (ADT). Radical prostatectomy (RP) is also an accepted treatment for patients with localized HR-PCa. Here we report a propensity score-matched analysis of institutional outcomes for patients with HR-PCa treated with RP or RT. Methods: Medical recor ds of patients with localized NCCN HR-PCa treated at our institution from 2002-2011 were reviewed. RT consisted of 73.8-77.4 Gray to the prostate and seminal vesicles; regional lymph nodes were treated for pre-treatment probability of involvement ≥15%. A combination of nearest neighbor propensity score matching on age, Adult Comorbidity Evaluation-27 score [a validated comorbidity index], prostate specific antigen (PSA), biopsy Gleason, and clinical T-stage (cT) and exact matching on PSA, biopsy Gleason, and cT was performed. Multivariate cox-proportional hazards regression was used to compare metastasis-free survival (MFS) and overall survival (OS) (calculated from date of diagnosis). Results: 246 patients were identified (160 RP and 86 RT). Propensity score matching resulted in 62 matched pairs. For the RP group, minimally invasive surgery (70.9%) and lymph node dissection (100%) were common. ADT was administered to 37.1% and 80.6% of patients receiving RP and RT, respectively. Median follow-up was longer for the RT group (51.4 vs 41 months, p = 0.004). Five-year rates of metastasis for RT and RP were 8.9% and 33% (p = 0.003), and for death were 25.9% and 17.6%, respectively (p = 0.31). MFS was significantly better for patients treated with definitive RT compared to RP, while OS was not different (Table). Conclusions: In our cohort with HR-PCa, treatment with RT resulted in a MFS advantage over RP. This was not accompanied by an improvement in OS.The difference in MFS may possibly be related to the importance of early adjuvant ADT. [Table: see text]

Abstract
OBJECTIVE To evaluate the sensitivity and specificity of urine aquaporin 1 (AQP1) and perilipin 2 (PLIN2) concentrations to diagnose clear cell or papillary renal cell carcinoma (RCC) by comparing urine concentrations of these unique biomarkers in patients with RCC, noncancer renal masses, bladder cancer, and prostate cancer. METHODS From February 1, 2012, through October 31, 2012, preoperative urine samples were obtained from patients with a presumptive diagnosis of RCC based on an imaged renal mass, prostate cancer, or transitional cell bladder cancer. Imaged renal masses were diagnosed postnephrectomy—as malignant or benign—by histology. Urine AQP1 and PLIN2 concentrations were measured by using a sensitive and specific Western blot and normalized to urine creatinine concentration. RESULTS Median concentrations of urine AQP1 and PLIN2 in patients with clear cell and papillary RCC (n=47) were 29 and 36 relative absorbance units/mg urine creatinine, respectively. In contrast, median concentrations in patients with bladder cancer (n=22) and prostate cancer (n=27), patients with chromophobe tumors (n=7), and patients with benign renal oncocytomas (n=9) and angiomyolipomas (n=7) were all less than 10 relative absorbance units/mg urine creatinine (Kruskal-Wallis test, P<.001 vs RCC for both biomarkers) and comparable with those in healthy controls. The area under the receiver operating characteristic curve ranged from 0.99 to 1.00 for both biomarkers. CONCLUSION These results support the specificity and sensitivity of urine AQP1 and PLIN2 concentrations for RCC. These novel tumor-specific proteins have high clinical validity and high potential as specific screening biomarkers for clear cell and papillary RCC as well as in the differential diagnosis of imaged renal masses.

SUBJECTS AND METHODS Participants completed a flare survey that asked them: 1) whether they had ever had flares ('symptoms that are much worse than usual') that lasted <1 h, >1 h and <1 day, and >1 day; and 2) for each duration of flare, to report: their average length and frequency; their typical levels of urological and pelvic pain symptoms; and their levels of healthcare utilization and bother. We compared participants' responses to their non-flare MAPP values and by duration of flare using generalized linear mixed models. RESULTS Of 85 participants, 76 (89.4%) completed the flare survey, 72 (94.7%) of whom reported experiencing flares. Flares varied widely in terms of their duration (seconds to months), frequency (several times per day to once per year or less), and intensity and type of symptoms (e.g. pelvic pain vs urological symptoms). Flares of all durations were associated with greater pelvic pain, urological symptoms, disruption to participants' activities and bother, with increasing severity of each of these factors as the duration of flares increased. Days-long flares were also associated with greater healthcare utilization. In addition to duration, symptoms (pelvic pain, in particular) were also significant determinants of flare-related bother. CONCLUSIONS Our findings suggest that flares are common and associated with greater symptoms, healthcare utilization, disruption and bother. Our findings also show the characteristics of flares most bothersome to patients (i.e. increased pelvic pain and duration), and thus of greatest importance to consider in future research on flare prevention and treatment.

Abstract
PURPOSE We compared symptoms between interstitial cystitis/bladder pain syndrome and overactive bladder based on patient self-reported symptoms on validated questionnaires. MATERIALS AND METHODS We prospectively recruited 26 patients diagnosed with interstitial cystitis/bladder pain syndrome, 53 diagnosed with overactive bladder and 30 healthy controls to participate in a questionnaire based study that inquired about lower urinary tract symptoms. The questionnaires used were GUPI, ICSI, ICPI, ICIQ-OAB, ICIQ-UI, IUSS, numerical rating scales of the severity of bladder pain, pressure or discomfort, and numerical rating scale of the severity of urgency and frequency symptoms. RESULTS On univariate analysis patients with interstitial cystitis/bladder pain syndrome reported significantly more severe pain symptoms than those with overactive bladder. Patients with overactive bladder reported significantly more severe urinary incontinence symptoms than those with interstitial cystitis/bladder pain syndrome. There was no difference in frequency and urgency severity between the groups. Surprisingly, 33% of patients with overactive bladder reported pain or discomfort when the bladder filled and 46% with interstitial cystitis/bladder pain syndrome reported urgency incontinence. On multivariate analysis ICIQ-UI total scores (p = 0.01) and bladder pain severity on the numerical rating scale (p <0.01) distinguished the 2 conditions with 90.6% sensitivity and 96.1% specificity. Overactive bladder had higher ICIQ-UI and lower numerical rating scale pain scores. CONCLUSIONS There is considerable overlap of self-reported symptoms between interstitial cystitis/bladder pain syndrome and overactive bladder. This overlap raises the possibility that the 2 conditions represent a continuum of a bladder hypersensitivity syndrome.

Abstract
OBJECTIVE To perform a population-based comparison of inflatable vs semirigid penile prostheses and to determine contemporary rates of reoperation and identify factors impacting the type of prosthetic implanted. METHODS Patient-level discharge data and revisit files from the Agency for Healthcare Research and Quality for semirigid and inflatable prosthesis procedures performed for erectile dysfunction from 2006 to 2009 in the state of California were examined. Regression analysis was performed to determine differences between the procedures in terms of infectious and noninfectious failure. Regression analysis was performed to identify factors associated with revision and to identify associations between potential risk factors and the type of implant performed. RESULTS A total of 2263 cases were included in the study (1824 inflatable and 439 semirigid). The overall reoperation rate was 7.42%. There was no difference in the overall revision rate between the 2 groups (7.52% semirigid and 7.40% inflatable; P=.94). The reoperation rate secondary to infectious complications was 3.6% (4.5% semirigid vs 3.23% inflatable; P=.18). The revision rate secondary to noninfectious failure was 2.96% in the semirigid vs 4.17% in the inflatable group (P=.25). Medicaid insurance (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.41-3.61), African American race (OR, 1.7; 95% CI, 1.20-2.49), age>80 (P=.046), and diabetes (OR, 1.67; 95% CI, 1.07-2.59) were associated with receiving a semirigid implant. CONCLUSION Reoperation rates for infectious and noninfectious failure are equivalent between the semirigid and inflatable penile prostheses. Sociodemographic factors appear to significantly influence the type of prosthesis a patient receives.
