5 Interesting Facts of Nonnephritic hematuria
- Hematuria may originate from ureter, bladder, or prostate due to malignancy, infection, trauma, or stones
- Clinical presentation may be distinctive (associated renal colic with stones, fever and dysuria with infection)
- Oliguria is unusual unless there is complete or partial obstruction by stones or malignancy
- Hypertension and edema are absent unless due to comorbidities
- Microscopic analysis of urine sediment aids in differentiation; red cells are morphologically normal and red cell casts are not present in nonglomerular causes of hematuria
