What characteristics of the clinical evaulation and urinalysis suggest a glomerular (nephrological), as opposed to a nonglomerular (renal pelvis, ureter, bladder, etc), cause of hematuria?
2+ or greater proteinuria
RBC casts
presence of at least 80% dysmorphic RBCs
elevated blood pressure
If the clinical evaluation and urinalysis suggest a glomerular cause of hematuria, then renal function should be measured and nephrology consult considered.
