The Investigation of Hematuria

Although hematuria is common, there is no uniform, internationally accepted, evidence-based algorithm for its diagnostic evaluation. All potential causes of hematuria must be considered, and all individual risk factors taken into account, so that an underlying disease requiring treatment can be identified or ruled out.

 What It Means When You See Blood In Your Urine

There are few moments more frightening than seeing blood in your urine. Happily, the cause is often not serious.

HEMATURIA...or Blood in the Urine

It’s interesting to note that every website you hit that mentions vigorous or strenuous exercise as a potential cause has no explanation for why.

A 4-step approach to asymptomatic microscopic hematuria

I lay out a 4-point plan for evaluating women with asymptomatic microscopic hematuria, based on the latest data in the medical literature.

Australia’s high rates of bladder cancer deaths show why blood in urine should always be investigated

Environmental risk factors are thought to be more important than genetic or inherited susceptibility when it comes to bladder cancer. The most significant known risk factor is cigarette smoking.

Evaluating haematuria in primary care

The cause of haematuria varies depending on the clinical presentation and the patient's age. The most common aetiologies are kidney or urinary tract malignancy, renal stones, cystitis, prostatitis or benign prostatic hyperplasia (BPH).

Haematuria in trauma

Haematuria in trauma may be microscopic (with or without symptoms) or macroscopic •In general, the greater the degree of hematuria the greater the risk of significant intra-abdominal injury (including non-urinary tract structures) •About 5% of renal injuries and up to 20% of renovascular injuries lack hematuria — even severe injuries such as renal artery injury or ureteropelvic disruption may present without hematuria

Hematuria Approach - Nephrology

The following Q and A aaproach will help you understand the principal concepts of Hematuria.

Hematuria as a Marker of Occult Urinary Tract Cancer: Advice for High-Value Care From the American College of Physicians

•Gross hematuria should be included in clinicians' routine review of systems. In particular, all patients with microscopic hematuria should be asked about their history of visible hematuria. •In asymptomatic adults, screening urinalysis shouldn't be used to detect cancer. •In asymptomatic patients, heme-positive results from dipstick tests should be confirmed with microscopic urinalysis demonstrating three or more erythrocytes per high-powered field. •All adults with visible hematuria, even if self-limited, should be referred for further urologic workup...

Macroscopic haematuria

Common urological causes of haematuria include urinary tract infection and ureteric and renal stones, but concurrent pathology should be suspected if haematuria is significant or persistent. Importantly, if benign conditions are excluded, and the haematuria continues, further investigation is advised, as this may be the only sign of an underlying genitourinary malignancy.

New App Turns Your iPhone Into a Mobile Urine Lab

For entrepreneur Myshkin Ingawale the logic was unassailable. Everybody pees. And everyone has a cellphone. “There has to be something going on there,” Ingawale told a chuckling crowd at the TED conference.

Primary Care Corner with Geoffrey Modest MD: Hematuria Evaluation

These guidelines do not discuss the most rational approach, in my opinion. It seems reasonable, though untested, to do a renal evaluation first. If there is evidence of a renal cause for hematuria (e.g., some combination of dysmorphic red cells, casts, proteinuria, renal dysfunction, abnormal radiologic assessment), I tend to pursue the renal workup at that point and consider referral to a nephrologist if the etiology remains unclear, there is progressive disease, the imaging study is concerning for a serious underlying pathology, etc. I am not convinced that everyone in this category needs cystoscopy.

Red flag symptoms: Haematuria

Haematuria is a symptom that should always prompt a thorough assessment. While there are several relatively benign causes, identification of any of the red flags should lead you to suspect the more sinister diagnoses of inflammatory renal disease and malignancy.
