It may present as urine that is red to brown, or as frank blood. As little as 1 mL of blood can impart colour to 1 L of urine.Visible haematuria, even when transient or asymptomatic, may indicate a significant disease process and always requires further

Hematuria Cancer Risk Score with Ultrasound Informs Cystoscopy Use in Patients with Hematuria. Hematuria is a cardinal symptom of urinary tract cancer and would require further investigations. To determine the ability of renal bladder ultrasound (RBUS) with the Hematuria Cancer Risk Score (HCRS) to inform cystoscopy use in patients with hematuria. The development cohort comprised 1984 patients with hematuria from 40 UK hospitals (DETECT 1; ClinicalTrials.gov: NCT02676180) who received RBUS. An independent validation cohort comprised 500 consecutive patients referred to secondary care for a suspicion of bladder cancer. Sensitivity and true negative of the HCRS and RBUS were assessed. A total of 134 (7%) and 36 (8%) patients in the development and validation cohorts, respectively, had a diagnosis
haematuria differs among children, adults under the age of 35 years, and adults aged 35 years or older.Patients with visible haematuria represent a higher-risk group for urological malignancy than those presenting with non-visible haematuria.[1]Nielsen M, Qaseem A.

[Clinical and genetic features of persistent asymptomatic microscopic hematuria in children]. To explore clinical and genetic features of persistent asymptomatic microscopic hematuria in children. A retrospective case analysis of 135 individuals admitted to Xi 'an Children's Hospital with persistent asymptomatic microscopic haematuria between January 2016 to December 2023 was conducted . The demographic characteristics, kidney pathology and gene results of 135 individuals were analyzed. One hundred and thirty-five individuals were divided into 2 groups (positive group and negative group) according to family history of glomerulogenic hematuria in first-degree relatives. The differences of hematuria remission, proteinuria and gene variation were compared between the 2 groups. Two independent
Efficacy of a clinical decision support tool to promote guideline concordant evaluations in patients with high-risk microscopic hematuria: a cluster randomized quality improvement project. We aimed to determine whether implementation of clinical decision support (CDS) tool integrated into the electronic health record (EHR) of a multi-site academic medical center increased the proportion of patients with American Urological Association (AUA) "high risk" microscopic hematuria (MH) who receive guideline concordant evaluations. We conducted a two-arm cluster randomized quality improvement project in which 202 ambulatory sites from a large health system were randomized to either have their physicians receive at time of test results an automated CDS alert for patients with 'high-risk' MH
Validation of a Quantitative Hematuria Scale. To develop a quantitative hematuria scale that assigns specific blood concentration percentages to commonly used descriptors such as "clear," "mild," "moderate," and "severe," in order to standardize hematuria severity assessments during Continuous Bladder Irrigation (CBI) and reduce reliance on subjective visual evaluations. Samples of bovine blood determined using mode and weighted averages. Overall agreement among respondents was moderate (Kappa=0.53, p < 0.0001). The categories "clear" and "severe" demonstrated substantial agreement (Kappa=0.63), while "moderate" and "mild" showed moderate and fair agreement, respectively. This study presents a promising foundation to a novel quantitative scale for hematuria assessment, reducing reliance

Utilization and Timing of Cystoscopy for Hematuria Evaluation by Advanced Practice Providers and Urologists. To characterize differences between urologists and advanced practice providers (APPs) in utilization of cystoscopy for hematuria. We identified patients initially evaluated for hematuria by a urologist or urology APP between 2015 and 2020 in the MarketScan® Research Databases. We determined whether they received a cystoscopy within six months of their urology visit and the number of days until cystoscopy. We used multivariable regression to analyze the association between these outcomes and whether the urology clinician was an advanced practice registered nurse (APRN), physician assistant (PA), or urologist. We identified 34,470 patients with microscopic hematuria and 17,328
Gross Hematuria Does not Affect the Selection of Nephrectomy Types for Clinical Stage 1 Clear Cell Renal Cell Carcinoma: A Multicenter, Retrospective Cohort Study. This study aimed to discuss the correlation between gross hematuria and postoperative upstaging (from T1 to T3a) in patients with cT1 clear cell renal cell carcinoma (ccRCC) and to compare oncologic outcomes of partial nephrectomy (PN ) and radical nephrectomy (RN) in patients with gross hematuria. A total of 2145 patients who met the criteria were enrolled in the study (including 363 patients with gross hematuria). The least absolute selection and shrinkage operator logistic regression was used to evaluate the risk factor of postoperative pathological upstaging. The propensity score matching (PSM) and stable inverse probability
approaches to management. We also report on successful use of a non-conjugated oestrogen which has a lower VTE risk compared to conjugated oestrogens. We aim to help support clinicians manage other palliative patients with this challenging symptom in future. Relevant references for this review were identified through searches of PubMed using the terms 'haematuria', 'hematuria', 'palliative Medical management of refractory haematuria in palliative patients. The management of haematuria, in patients with a palliative diagnosis, refractory to standard measures presents a significant challenge for multi-disciplinary teams. Our experiences with two cases led us to review the literature and highlighted the limited evidence base. We describe the cases here and propose options for medical
