RENAL DISEASES The Nephron Consists of the glomerulus and its attached tubules. The functional unit of the kidney. Major Renal Syndromes Acute Nephritic Syndrome The Nephrotic Syndrome Rapidly Progressive Glomerulonephritis Asymptomatic Hematuria or Proteinuria Major Renal Syndromes (cont) Acute Renal Failure Urinary Tract Infection Nephrolithiasis Acute Nephritic Syndrome Sudden onset of hematuria with RBC casts and renal failure (days - weeks) RBC casts not listed in the book!! But this is critical!! Proteinuria (mild to moderate but NOT Nephrotic Range) Hypertension Hallmark Disease: Post Streptococcal Glomerulonephritis What is an RBC cast? The Nephrotic Syndrome Proteinuria ( 3.5gm/day) Hypoalbuminemia Edema Hyperlipidema Lipiduria Rapidly Progressive Glomerulonephritis Nephronal hematuria Renal failure developing over weeks to months Diffuse glomerular crescent formation. Asymptomatic Hematuria or Proteinuria Hematuria with or without RBC casts and/or Proteinuria usually 2.0gm/day NO RENAL FAILURE NO NEPHROTIC SYNDROME Acute Renal Failure Oliguria ( 400ml/day) Rarely anuria Recent Onset of Azotemia (hours/days) Chronic Renal Failure Uremia Final Common Path of All Chronic Renal Diseases Urinary Tract Infection Bacteriuria and Pyuria Dysuria, Frequency, Urgency Pyelonephritis or Cystitis WBC casts = Pyelonephritis The Book Misses this one!!..
