Hematuria classified acc to appearance
Macroscopic hematuria (gross hematuria)
- Suggests damage to the kidneys, upper/lower urinary tract
Microscopic hematuria
- RBCs are present in the urine sediment but no urine discoloration
- Can indicate damage to the glomeruli
Hematuria classified acc to timing when voiding
Initial hematuria: at beginning of micturition and clears by the end
- Suggests urethral damage
Terminal hematuria: blood or clots during the last part of micturition
- Suggests damage to the bladder neck, prostate, or trigonal area
Total hematuria: throughout the entire micturition
- Suggests damage to the bladder, ureters or kidneys
Painless hematuria (asymptomatic hematuria)
- Suggests malignancy
etiology of non-glomeruli hematuria
Urolithiasis
Infection
- Cystitis
- Urethritis
- Prostatitis
Malignancy: especially if otherwise asymptomatic
