Study Notes
- Albuminuria is an early sign of renal involvement in diabetes mellitus, detected via urinalysis.
- Urinalysis can reveal excess glucose, acetone bodies, ketones, pus, phenylketones, hemoglobin, and bilirubin.
- UTIs affect kidneys, ureters, bladder, and urethra, leading to renal failure and potential end-stage kidney disease.
- Inflammatory disorders like interstitial nephritis can lead to poor renal function, fever, skin rash, eosinophils, and pyelonephritis.
- Renal abscesses can be visualized via CT scans, and urethral and ureteral inflammation or blockages can cause symptoms like diminished force, dysuria, polyuria, hesitation, and nocturia.
- Kidney stones are formed by high calcium levels and can be caused by chronic dehydration, gout, urinary tract infections, or dietary choices.
- Polycystic kidney disease is a progressive condition causing multiple fluid-filled sacs inside and outside the kidneys.
- Uremia and azotemia refer to high levels of nitrogenous wastes in the blood.
- Nephrotic syndrome is a kidney disease characterized by proteinuria, hypoalbuminemia, and edema.
- Glomerulonephritis is inflammation of the glomeruli in the kidney, causing leaky glomeruli and leading to symptoms like blood in the urine, increased urinary frequency, and dysuria.
- Imaging techniques like CT scans, retrograde pyelograms, and MRI can help diagnose kidney and bladder disorders and tumors.
- Diagnostic procedures like blood urea nitrogen and creatinine clearance tests can measure the amount of urea and nitrogen in the blood and assess renal function.
Test your knowledge about the relationship between diabetes mellitus and urinalysis results. Learn to recognize the signs of renal involvement and abnormal levels of glucose, albumin, and ketone bodies in the urine.
