Hematuria Articles

Patients with metastatic and locally advanced bladder or prostate cancer may suffer from pelvic symptoms such as pain, obstruction, and hemorrhage. Local tumor growth is associated with significant morbidity and systemic therapy is often ineffective.

ORLANDO, FL USA (UroToday.com) - Hematuria is associated with renal cell carcinoma (RCC). However, its relationship with specific pathologic subtypes has not been evaluated. Michael Hanzly and colleagues sought to evaluate whether hematuria could be predictive for subtype of RCC and benign renal masses.

Determine if "bag-squeeze" technique decreases pain during flexible cystoscopy in men.

A single center, prospective, double-blinded randomized controlled trial recruiting 200 consenting participants who were ambulatory, outpatient males who had undergone a prior cystoscopy and were not expected to require any secondary procedures.

The vast majority of patients who undergo a diagnostic evaluation for microscopic hematuria (MH) do not have occult bladder cancer. Identifying patients with MH at high risk of harboring bladder cancer can allow for a risk adjusted approach to diagnostic interventions with the goal of safely reducing unnecessary evaluations.

The present study investigated the use of retrograde flexible ureteroscopy (RFU) in the discrimination of the etiology of hematuria that originates from the upper urinary tract (UUT). The present study collected retrospective data for patients who presented with hematuria and cystoscopy-detected bleeding from the UUT between June 2006 and August 2018 in Ningbo First Hospital.

The present study sought to identify a panel of DNA markers for noninvasive diagnosis using cell-free DNA (cfDNA) from urine supernatant or cellular DNA from urine sediments of hematuria patients. A panel of 48 bladder cancer-specific genes was selected.

Despite suboptimal sensitivity, urine cytology is often performed as an adjunct to cystoscopy for bladder cancer diagnosis. We aimed to develop a non-invasive, fast molecular diagnostic test for bladder cancer detection with better sensitivity than urine cytology while maintaining adequate specificity.

To report the incidence of urinary tract malignancies (UTM) and to compare the diagnostic accuracy of cytology with cystoscopy, renal ultrasound (US) and computed tomography (CT) in patients with hematuria.

Urinary cell-free DNA (ucfDNA) has great potential as a "liquid biopsy" for use in diagnosis of urological cancers. In this study, we compared ucfDNA gene expression levels between patients with bladder cancer (BC) and those with hematuria, and determined whether they could be used as a noninvasive urine-based marker.

Urinary retention and hematuria owing to radiation-induced mucositis are occasional late adverse events in patients with prostate cancer. Moreover, radiation-induced secondary malignancies are late adverse events, although they are extremely rare.

The aim of this study was to evaluate the dose-volume histogram parameters for late hematuria and rectal hemorrhage in patients receiving radiotherapy after radical prostatectomy.

Data of 86 patients treated between January 2006 and June 2019 were retrospectively evaluated.

Eosinophilia can be a manifestation of a variety of causes such as infections, allergic reactions and autoimmune processes. Also, it is described in various solid malignancies in the presence of tumour eosinophilic infiltration.

Many patients enter the care cycle with gross or microscopic hematuria and undergo a cystoscopy to rule out bladder cancer. Sensitivity of this invasive examination is limited, leaving many patients at risk of having undetected cancer.

To develop technical guidelines for magnetic resonance imaging aimed at characterising renal masses (multiparametric magnetic resonance imaging, mpMRI) and at imaging the bladder and upper urinary tract (magnetic resonance urography, MRU).

Although many treatments have been applied to treat hormone-refractory prostate cancer (HRPC), therapeutic outcome is not altogether satisfactory.

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.

Bladder cancer is the fourth most common cancer in men, and is associated with significant morbidity and mortality. Pathologic evaluation of urothelial cancers relies predominantly on histomorphologic features but can be aided in a small subset of cases by immunohistochemical analyses.

MDCTU is a preferred method for the investigation of malignant lesions in the upper urinary tract. However, to decrease unnecessary radiation exposure the indications for the exam in different groups of patients should be assessed.

The occurrence of primary carcinoma of the ureteral stump following radical nephrectomy for renal cell carcinoma is extremely rare; 7 patients with the disease have been reported previously. All these patients were males with transitional cell carcinoma.

Small cell carcinoma of the urinary bladder (SCCB) is an extremely rare but aggressive tumour constituting less than 0.7% of all urinary bladder tumours. It is often misdiagnosed as transitional cell carcinoma, owing to the similarities in presentation.

We present the radiologic findings in a case of prostate brachytherapy seed migration to the bladder presenting as gross hematuria. While prostate brachytherapy seed implantation is considered a relatively safe procedure, migration is not uncommon; however, it is usually clinically silent and the seeds most commonly migrate to the lungs through the venous circulation via the periprostatic venous plexus.

To present outcomes for prostatic artery embolization (PAE) to treat urinary retention and gross prostatic hematuria in non-index benign prostatic hyperplasia (BPH) patients.

and Methods: 75 patients undergoing PAE from December 2013 through August 2018 (age=77.

The three-way indwelling urinary catheter (IUC) is used for continuous bladder irrigation and is considered the cornerstone for clinical treatment of patients with macroscopic hematuria. Although there seems to be a logical relationship between catheter size and efficacy of irrigation and drainage, we often observe relevant variations in these parameters between different brands of catheters available on the market.

The determination of urethral stricture was according to the Purohit-Blaivas staging system. Exclusion criteria were men who were performing intermittent catheterization and those that had intervention between cystoscopies.

To investigate the symptoms and delays in the clinical pathway of bladder cancer (BC).

This is a substudy of a prospective, randomized, multicenter phase III study (FinnBladder 9, NCT01675219) where the efficacy of photodynamic diagnosis and 6 weekly optimized mitomycin C instillations are studied in pTa bladder cancer with high risk for recurrence.

This paper is to elucidate the correlation between different symptoms of UTUC and the clinicopathological characteristics and prognosis. The clinicopathological data of 700 consecutive patients with UTUC who were treated with radical nephroureterectomy were reviewed, and symptoms were categorized into three groups: S1-no direct symptoms, S2-local symptoms (including hematuria and flank pain) and S3-systemic symptoms.

To evaluate the effects of short term use of finasteride and dutasteride on amount of intraoperative blood loss and microvessel density (MVD) of prostatic stromal and suburethral tissues in patients with benign prostatic hyperplasia (BPH) prior to TURP METHODS: The study involved 450 male patients who planned to have TURP and were prospectively randomised into three groups (150 patients each).

The most common symptom of bladder cancer (BC) is hematuria. However, not all patients with hematuria are diagnosed with BC. Here, we explored a novel method to discriminate BC from hematuria under non-malignant conditions by measuring differences in urinary cell-free microRNA (miRNA) expression between patients with BC and those with hematuria.

Early diagnosis of bladder cancer is crucial for improvement of cancer specific survival and recurrence rate. We analyzed the possible role of fluorescence urine analysis in bladder cancer diagnosis.

To better characterize the urinary microbiome in males and contribute to overall understanding of the urinary microbiota specifically in patients undergoing evaluation for possible bladder cancer, stratified by risk exposure to smoking.

After obtaining ethical and legal authorization, we performed a restrospective monocentric study.

Bladder urothelial papilloma is extremely rare in the paediatric population. It usually presents as painless gross haematuria and its diagnosis implies a high index of suspicion as other causes of haematuria predominate in this age range.

Only 3-28% of patients referred to the urology clinic for hematuria are diagnosed with bladder cancer (BC). Cystoscopies lead to high diagnostic costs and patient burden. Therefore, to improve selection of patients for cystoscopy, reduce costs and over-testing we aimed to validate a recently developed diagnostic urine assay MATERIALS AND METHODS: We included 200 patients from three European countries undergoing cystoscopy for hematuria (n=97 BC, n=103 non-malignant).
