Depending on the amount and duration of the damage occurring to the glomerulus in the previously discussed glomerular disorders, progression to chronic glomerulonephritis and end-stage renal disease may occur. Gradually worsening symptoms include fatigue, anemia, hypertension, edema, and oliguria. Examination of the urine reveals hematuria, proteinuria, glucosuria as a result of tubular dysfunction, and many varieties of casts, including broad casts. A markedly decreased glomerular filtration rate is present in conjunction with increased BUN and creatinine levels and electrolyte imbalance
