Patients presenting with microhematuria represent a heterogeneous population with a broad spectrum of risk for genitourinary malignancy. Recognizing that patient-specific characteristics modify the risk of underlying malignant etiologies, this guideline sought to provide a personalized diagnostic testing strategy.The systematic review incorporated evidence published from January 2010 through February 2019, with an updated literature search to include studies published up to December 2019. Evidence-based statements were developed by the expert Panel, with statement type linked to evidence strength, level of certainty, and the Panel's judgment regarding the balance between benefits and risks/burdens.Microhematuria should be defined as ≥ 3 red blood cells per high power field on microscopic evaluation of a single specimen. In patients diagnosed with gynecologic or non-malignant genitourinary sources of microhematuria, clinicians should repeat urinalysis following resolution of the gynecologic or non-malignant genitourinary cause. The Panel created a risk classification system for patients with microhematuria, stratified as low-, intermediate-, or high-risk for genitourinary malignancy. Risk groups were based on factors including age, sex, smoking and other urothelial cancer risk factors, degree and persistence of microhematuria, as well as prior gross hematuria. Diagnostic evaluation with cystoscopy and upper tract imaging was recommended according to patient risk and involving shared decision-making. Statements also inform follow-up after a negative microhematuria evaluation.Patients with microhematuria should be classified based on their risk of genitourinary malignancy and evaluated with a risk-based strategy. Future high-quality studies are required to improve the care of these patients.

Metformin is commonly prescribed for patients with type 2 diabetes mellitus. We hypothesized that metformin plus androgen deprivation therapy may be beneficial in combination. Our objective was to assess this combination in a retrospective cohort of patients with advanced prostate cancer.Using national Veterans Affairs databases we identified all men diagnosed with prostate cancer between 2000 and 2008 who were treated with androgen deprivation therapy with followup through May 2016. Study exclusions included treatment with androgen deprivation therapy for 6 months or longer, or receipt of androgen deprivation therapy concurrently with localized radiation. Three patient cohorts were developed, including no diabetes mellitus, diabetes mellitus with no metformin and diabetes mellitus with metformin. Cox proportional HRs were calculated for overall survival, skeletal related events and cancer specific survival.After exclusions the cohort consisted of 87,344 patients, including 61% with no diabetes mellitus, 22% with diabetes mellitus and no metformin, and 17% with diabetes mellitus on metformin. Cox proportional hazard analysis of overall survival showed improved survival in men with diabetes mellitus on metformin (HR 0.82, 95% CI 0.78-0.86) compared to those with diabetes mellitus who were not on metformin (HR 1.03, 95% CI 0.99-1.08). The reference group was men with no diabetes mellitus. Cox proportional hazard analysis of predictors of skeletal related events revealed a HR of 0.82 (95% CI 0.72-0.93) in men with diabetes mellitus on metformin. Cox proportional hazard analysis of cancer specific survival showed improved survival in men with diabetes mellitus on metformin (HR 0.70, 95% CI 0.64-0.77) vs those with diabetes mellitus without metformin (HR 0.93, 95% CI 0.85- 1.00). The reference group was men with no diabetes mellitus.Metformin use in veterans with prostate cancer who receive androgen deprivation therapy is associated with improved oncologic outcomes. This association should be evaluated in a prospective clinical trial.

Purpose: We assessed the performance of the EORTC (European Organisation for Research and Treatment of Cancer) and CUETO (Club Urologico Espanol de Tratamiento Oncologico) nonmuscle invasive bladder cancer predictive models compared to current United States NCCN Guidelines® in an American population.Materials and Methods: We retrospectively analyzed the electronic medical records of patients with nonmuscle invasive bladder cancer in a multicenter population in the United States. We evaluated recurrence-free and progression-free survival according to EORTC and CUETO, and assessed discriminative performance with the c-index at 1 and 5 years. We then compared the discrimination of EORTC and CUETO to the discrimination of the 4 nonmuscle invasive bladder cancer treatment groups described in NCCN Guidelines.Results: We identified 1,333 patients with nonmuscle invasive bladder cancer and a median followup of 37 months. At 5 years the recurrence c-index of EORTC and CUETO was 0.59 and 0.56 while for progression ...

Malnutrition is emerging as a significant factor in patient outcomes. A contemporary review of malnutrition has not been performed for the urologist. We review the available literature and current standards of care for malnutrition screening, assessment and intervention, focusing on patients with bladder cancer treated with cystectomy.Our multidisciplinary team searched PubMed® for available literature on malnutrition, focusing on definition and significance, importance to urologists, screening, assessment, diagnosis, immunological and economic impacts, and interventions.The prevalence of malnutrition in hospitalized patients is estimated to range from 15% to 60%, reaching upward of 71% in those with cancer. Malnutrition has been shown to increase inflammatory markers, further intensifying catabolism and weight loss. Bladder cancer is catabolic and patients undergoing cystectomy have increased resting energy expenditure postoperatively. Data are emerging on the impact of malnutrition in the cystectomy population. Recent studies have identified poor nutritional status based on low albumin or sarcopenia (loss of muscle) as having an adverse impact on length of hospitalization, complications and survival. The current standard of care malnutrition assessment tool, the 2012 consensus statement of the Academy of Nutrition and Dietetics and the American Society for Parenteral and Enteral Nutrition, has not been evaluated in the urological literature. Perioperative immunonutrition in patients undergoing colorectal surgery has been associated with significant decreases in postoperative complications, and recent pilot work has identified the potential for immunonutrition to positively impact the cystectomy population.Malnutrition has a significant impact on surgical patients, including those with bladder cancer. There are emerging data in the urological literature regarding how best to identify and improve the nutritional status of patients undergoing cystectomy. Additional research is needed to identify malnutrition in these patients and interventions to improve surgical outcomes.

Hexaminolevulinate hydrochloride with blue light cystoscopy is approved by the U.S. Food and Drug Administration as an adjunct to white light cystoscopy for the detection of urothelial cell carcinoma. In this study we examined the tolerability of the repeat use of white light cystoscopy with blue light cystoscopy.We retrospectively reviewed the records of all patients who underwent white light cystoscopy with blue light cystoscopy using hexaminolevulinate hydrochloride during a 34-month period at 2 institutions. We compared the incidence of adverse events after initial and subsequent procedures. We grouped, graded and assigned the degree of attribution for all adverse events.A total of 180 patients underwent 269 white light cystoscopy with blue light cystoscopy procedures. Of those 180 patients 118 (65%) underwent white light cystoscopy with blue light cystoscopy only 1 time. The other 62 (35%) patients underwent white light cystoscopy with blue light cystoscopy 2 or more times, including 43 (24%) 2 times and 19 (10%) 3 or more times. We noted 89 adverse events out of 269 procedures (33%), of which 66 (74%) occurred after the first white light cystoscopy with blue light cystoscopy; 14 (16%) after the second time and 9 (10%) after the third time or more. We found no statistically significant difference in adverse events between those patients undergoing 1 vs 2 or more white light cystoscopy with blue light cystoscopy procedures (p=0.134). We observed 1 grade 3 adverse event and no grade 4 or 5 adverse events. None of the adverse events were classified as probably or definitely related to hexaminolevulinate hydrochloride.In this retrospective study we found no statistically significant difference in the frequency or the grade of adverse events between first and repeat use of white light cystoscopy with blue light cystoscopy using hexaminolevulinate hydrochloride.

INTRODUCTION AND OBJECTIVES:There is a growing body of evidence suggesting possible therapeutic role of statin medications on advanced prostate cancer outcomes. However, little is known regarding the impact of the type of statin medications used, the dose of statins received, or the duration of treatment with this class of medications on PCa outcomes. Our goal was to investigate the impact of the statin type, dose and duration on oncologic outcomes in patients with advanced prostate cancer who are treated with androgen deprivation therapy (ADT).METHODS:We used the national VA database to identify all men diagnosed with PCa who are receiving ADT and were treated with statin medications for at least 6 months after PCa diagnosis between 2000 and 2008 with follow-up through May 2016. Patients were then stratified based on the type of statins (hydrophilic vs. lipophilic), the cumulative dose of statins (based on WHO defined daily dose for each statin medication), and the total duration of statins use (< 12 mon...
