ORTALITY/MORBIDITY IN GENERAL, CHILDREN WITH ISOLATED ASYMPTOMATIC MICROSCOPIC HEMATURIA TEND TO DO WELL, WHEREAS THOSE WITH ASSOCIATED FINDINGS (EG, HYPERTENSION, PROTEINURIA, ABNORMAL SERUM CREATININE LEVELS) ARE MORE LIKELY TO HAVE SERIOUS PROBLEMS.

INCIDENCE OF HEMATURIA IN SPECIFIC RACIAL GROUPS IS DETERMINED BY THE PRIMARY CAUSE, FOR EXAMPLE, IDIOPATHIC HYPERCALCIURIA IS INFREQUENT IN BLACK AND ASIAN CHILDREN, BUT RELATIVELY COMMON IN WHITES. CONVERSELY, HEMATURIA CAUSED BY SICKLE CELL DISEASE IS MORE C M IN BLACKS THAN IN WHITES.
SEX: MAY PREDISPOSE A CHILD TO SPECIFIC DISEASES THAT MANIFEST AS HEMATURIA. FOR EXAMPLE, THE SEX- LINKED FORM OF ALPORT SYNDROME HAS A MALE PREPONDERANCE, WHEREAS LUPUS NEPHRITIS IS MORE COMMON IN ADOLESCENT GIRLS
AGE: NCE OF CERTAIN CONDITIONS VARIES 3R INSTANCE, WILMS TUMORS ARE MORE CHILDREN OF PRESCHOOL AGE, WHEREAS ACUTE POSTINFECTIOUS GLOMERULONEPHRITIS IS MORE FREQUENT IN THE SCHOOL- AGED POPULATION. IN ADULTS, HEMATURIA IS OFTEN A SIGN OF MALIGNANCY OF THE GENITOURINARY TRACT (EG, RENAL CELL CARCINOMA, BLADDER TUMORS, PROSTATIC TUMORS). THESE CONDITIONS ARE RARE IN CHILDREN.
