Diagnostic Tests for Reduced urine

Diagnostic Test list for Reduced urine:

The list of diagnostic tests mentioned in various sources as used in the diagnosis of Reduced urine includes:

• Physical examination
  • Blood pressure. If there is high blood pressure and reduced or lack of urine should consider acute or chronic glomerulonephritis, polycystic kidneys, acute tubular necrosis or dissecting aneurysm. If there is low blood pressure should consider dehydration, blood loss, an acute abdomen and other causes of shock
  • Cardiovascular examination looking for signs of an enlarged heart which may suggest congestive heart failure
  • Abdominal examination feeling for enlarged kidneys. Bilaterally enlarged kidneys would suggest bilateral hydronephrosis or polycystic kidneys. Unilateral enlarged kidneys is not usually associated with reduced or lack of urine
  • Examine for enlargement of the bladder. Enlargement of the bladder may suggest bladder neck obstruction (due to benign enlargement of the prostate, prostate cancer or urethral stricture)
  • Pelvic examination for pelvic mass which may be obstructing the ureter
  • Per rectal examination to determine the size and consistency of the prostate
• Pass a catheter into the bladder - will determine if bladder neck is obstructed which will be diagnosed when a large amount of urine is drained. Lack of urine suggests urinary tract obstruction until proved otherwise. Bladder outflow obstruction must always be considered first.
• Blood tests
  • Full blood test
  • Electrolytes
  • Renal function tests
  • Creatinine ratio
  • Serum protein electrophoresis
  • ANA autoantibodies
  • Anti-streptolysin O titers and serum complement level if suspect glomerulonephritis
  • Serum Haptoglobin, if suspect intravascular hemolysis
  • Prostate specific antigen
  • Blood cultures, if unwell and fever
• Urine tests
  • Urinalysis
  • Spot urine sodium
  • Urine microscopy and culture - examine the urinary sediment will help identify cases of acute glomerulonephritis, lupus erythematosus and acute tubular necrosis.
• Cystoscopy - by urologist to directly view any obstructing lesions within the bladder and urethra.
• Radiological investigations
  • Retrograde pyelography
  • Renal ultrasound scan may detect dilated parts of the kidney or ureter due to obstruction
  • Renal angiography and aortography, if suspect dissecting aneurysm or bilateral renal artery stenosis
  • Abdominal ultrasound scan is helpful in diagnosing polycystic kidneys and pelvic masses that may be obstructing the ureter
  • CT Scan of abdomen may be necessary to diagnose polycystic kidneys and pelvic masses that may be obstructing the ureter
  • Echocardiogram to determine left ventricular ejection fraction, if suspect congestive cardiac failure as cause of reduced urine output
• Biopsy of the kidney - may be necessary to diagnose the various collagen diseases and some forms of glomerulonephritis.
