Hematuria - A Diagnostic Approach Douglas Stahura D.O. GVH 8/24/00
Goals Epidemiology Evaluation Differential Diagnosis Case Reports
Hematuria - Epidemiology Definitions –Macroscopic - pink, red, or tea colored –Microscopic - >4 RBCs per hpf of spun urine sediment Prevalence –School aged - 4% (always check a 2nd specimen) –>35 y/o - 13% –PPV low, most useful in elderly men
Hematuria - Epidemiology Specific –Glomerular causes - –Predominate in children and young adults –>40 y/o only 5% of cases –Neoplasm –>40 y/o, Urinary tract 15-20% of cases –Children: Wilms tumor, Rhabdomyosarcoma of bladder
Hematuria - Evaluation History Physical Urinalysis
Hematuria - Evaluation
Urinalysis –Proteinuria - indicator of glomerular disease can be up to 500 mg/24 hr in gross hematuria –RBC cast - must look at urine with your own eyes –Pyuria - look for UTI/STD –Crystals –Dysmorphic RBCs
Hematuria - Cases Case 1 –22 y/o WF gross hematuria x2 days –mother of 2: 4y/o, 4mo –works 12 hr shift as waitress, 3 in 4 d –monagamous x 2 years –+/- dysuria, +/- flank pain –PE - no trauma –UA - pro 2+, WBC 5-10/hpf, Bac 1+

Denies trauma. + warmth/erythema x4d –Teated with Keflex x 7d. –10 d post ATBX, notices blood in urine –PE - L arm nl, 150/85, NAD –UA RBC/hpf, occ dysmorphic rbc, no casts, bac, WBC reported.
Hematuria - Cases Case 8 –20 y/o Japanese exchange student presents with URI sx x1 day. Cough, low grade fever, headache, myalgias. On day two, notices blood in urine. –PE - t=99.2, cough, no sputum, minimal distress. –UA - RBC TNTC, Pro 4+, no casts, no bac.
