I now have all the material needed for a comprehensive answer.

Hematuria

Hematuria is the presence of blood in the urine. It is a urologic sign, not a diagnosis, and mandates evaluation because it may signal urologic cancer in up to 25% of cases.

Definition

TypeDefinition
Gross hematuriaVisible blood in urine; as little as 1 mL blood per liter of urine turns urine red
Microscopic hematuria≥ 3 RBCs/high-power field (HPF) on urine microscopy in adults
Pediatric threshold> 5 RBCs/HPF on at least 2 weekly samples is considered abnormal
Persistence = hematuria in > 50% of urine samples on 2-3 separate occasions.

Pseudohematuria - Rule Out First

Red-colored urine without true RBCs on microscopy:
  • Drugs: phenazopyridine, rifampin, nitrofurantoin, chloroquine, hydroxychloroquine
  • Foods: beets, berries, rhubarb, food coloring
  • Other: iodine, bromide
The dipstick alone is insufficient - urine microscopy is mandatory to confirm true hematuria. After centrifugation, red color in the sediment = true hematuria; red supernatant with no RBCs = pseudohematuria.

Classification by Stream Pattern

PatternLikely Origin
Initial streamProstatic or urethral source
Terminal streamBladder neck / trigone
Throughout streamBladder, ureter, or upper tract
Clot morphology: Vermiform (worm-shaped) clots arise from the upper urinary tract; cuboid clots form in the bladder.

Causes (Differential Diagnosis)

Upper Urinary Tract

  • Glomerular: IgA nephropathy, thin basement membrane disease, Alport syndrome, post-infectious GN, lupus nephritis
  • Non-glomerular: Renal cell carcinoma, urothelial carcinoma of renal pelvis, urolithiasis, polycystic kidney disease, renal papillary necrosis, trauma, AVM
  • Infections: Pyelonephritis, renal tuberculosis, schistosomiasis

Lower Urinary Tract

  • Bladder cancer (most common cause of gross hematuria in patients > 50 years old)
  • Urothelial carcinoma
  • Cystitis (bacterial, radiation, cyclophosphamide-induced)
  • Benign prostatic hyperplasia (BPH - increased vascularity, not a direct cause)
  • Prostate cancer
  • Urethritis, urethral stricture

Systemic / Other

  • Sickle cell disease (vasoocclusion in renal medulla; characteristically left-sided and 4x more common from the left kidney due to higher left renal vein pressure)
  • Coagulopathy / anticoagulants (supratherapeutic anticoagulation; therapeutic levels do not cause spontaneous hematuria)
  • Exercise-induced (transient, self-limited)
  • Endometriosis of urinary tract (cyclical hematuria with menstruation)
  • Trauma (post-renal transplant anastomosis, biopsy-related AV fistula)

Risk Factors for Urologic Malignancy

  • Age > 35-50 years
  • Male sex
  • Smoking history
  • Industrial chemical exposure (aniline dyes, benzidine, petroleum products)
  • Alkylating chemotherapy (cyclophosphamide)
  • Analgesic abuse
  • Chronic foreign bodies in the urinary tract
  • Chronic recurrent UTIs

Diagnostic Clues on History & Exam

  • UTI symptoms (dysuria, frequency, urgency) - treat and recheck; if microscopic hematuria resolves post-treatment, no further workup needed
  • Flank pain - nephrolithiasis or pyelonephritis
  • Painless gross hematuria - malignancy until proven otherwise
  • Hypertension + edema - glomerular disease
  • Cola-colored urine + proteinuria + dysmorphic RBCs + RBC casts - glomerulonephritis (refer to nephrology)
  • Abdominal bruit - AV fistula; pulsatile mass - AAA (life-threatening)

Diagnostic Workup

Step 1 - Urinalysis with Microscopy

  • Confirm true hematuria
  • Look for: RBC casts, dysmorphic RBCs (glomerular origin), WBCs, proteinuria

Step 2 - Urine Culture

  • Exclude infection before proceeding

Step 3 - Imaging

  • CT urography (multiphasic) - preferred; evaluates renal parenchyma, urothelium of upper tracts, identifies hydronephrosis, stones, masses
  • MR urography - for patients with contrast contraindications
  • Renal ultrasound - acceptable alternative when CT unavailable

Step 4 - Cystoscopy

Per AUA guidelines, recommended for:
  • All patients ≥ 35 years with microhematuria
  • Any age with gross hematuria
  • Any age with risk factors for urologic malignancy (tobacco use, chemical exposure)

Step 5 - Renal Function

  • BUN, creatinine, eGFR
  • 24-hour urine if nephrologic cause suspected

Step 6 - Nephrology Referral

Indicated when glomerular origin suspected (dysmorphic RBCs, RBC casts, significant proteinuria, hypertension, impaired GFR)

Special Contexts

Trauma

  • Gross hematuria with trauma = renal imaging (CT with contrast) mandatory
  • Degree of hematuria does not reliably correlate with severity of injury
  • Hematuria absent in ~7% of Grade IV renal injuries and ~50% of ureteropelvic junction injuries
  • Microscopic hematuria + hemodynamic shock = high risk for major renal injury

Renal Transplant

  • Immediate post-op hematuria = ureterovesical anastomosis issue (usually self-limited)
  • Persistent post-biopsy hematuria = AV fistula (diagnose with Duplex US; 70% resolve spontaneously; embolization if persistent)
  • AMH in transplant recipients - evaluate per AUA guidelines + add BK virus to differential

Sickle Cell Disease

  • Gross hematuria, typically unilateral, left kidney predominant
  • Conservative management: bed rest, high urine output, urine alkalinization (theoretical benefit)
  • Antifibrinolytics (epsilon-aminocaproic acid, tranexamic acid) for massive/persistent hemorrhage - use with caution (prothrombotic)
  • Surgical/embolization/nephrectomy reserved for refractory cases

2025 AUA/SUFU Guideline Update (Key Points)

The 2025 AUA/SUFU Microhematuria Guideline Amendment (Barocas et al., J Urol 2025, PMID: 40013563) introduced:
  • Revised risk stratification system for microhematuria
  • Updated guidance on urine-based tumor markers and cytology
  • New guidance on diagnosis and surveillance follow-up schedules

Follow-up for Negative Evaluation

After a complete negative workup for persistent microhematuria:
  • Annual urinalysis
  • Repeat urologic examination consideration every 3-5 years

The flowchart is complete and looks great - all the nodes, decision diamonds, branching paths, and color-coded lanes are rendering correctly. Here's your download:

What's in the flowchart

The single wide-format slide walks through the full AUA/SUFU 2025 decision pathway across 5 color-coded lanes:
ColorRepresents
🔵 BlueEntry node and workup steps
🟣 PurpleDecision diamonds (Yes/No branches)
🟠 OrangeUrgent workup (gross hematuria, high-risk)
🔴 Red/PinkHigh-risk malignancy path
🟢 GreenBenign/low-risk path and resolved cases
🟤 Dark PurpleNephrology referral

Flow summary

  1. Entry - Red/colored urine
  2. Step 1 - Urine microscopy: ≥3 RBCs/HPF? - If NO → pseudohematuria (drugs, foods), stop
  3. Step 2 - Benign cause (UTI, menstruation, exercise, trauma)? - If YES → treat and repeat UA in 6 weeks
  4. Step 3 - Type split: Gross (left path) vs Microscopic (right path)
  5. Gross path - Urgent CT urography + renal US + cystoscopy for all ages; glomerular signs? → nephrology
  6. Micro path - Age ≥35 or risk factors? YES → full workup (CT urography + cystoscopy + cytology); NO → renal imaging + annual UA x3 years
  7. Risk factors callout - Smoking, aniline dyes, cyclophosphamide, chronic UTI, male sex, age >35
  8. Pediatric note - Threshold >5 RBCs/HPF on 2 weekly samples; cystoscopy rarely indicated <18 yrs; prioritize nephrology
