classification of vesicureteral reflex (VUR) - 5 grades
grade 1: doesn’t reach renal pelvis
grade 2: up to renal pelvis w/o dilation
grade 3: renal pelvis w/ mild-moderate dilation
grade 4-5: distention of renal pelvis, reflux into intrarenal collecting system
S+S glomerulonephritis
-puffiness of face, edema
-dark colored urine (tea/cola colored)
-pale
-irritable, lethargic
-anorexia
-decreased urine output
-mild-moderate elevation in BP
-elevated BUN and Cr
-decreased GFR
-urine contains protein and blood
signs of improving glomerulonephritis
increased urine output
decreased BUN and Cr
Tx glomerulonephritis
-fluid and Na restrictions
-BP Tx q4-6h
-avoid fatigue
-spontaneous recovery (no specific Tx)
