Urinary Tract

  • Decrease in renal mass
  • Decrease in glomerular filtration rate
  • Decrease in renal blood flow
  • Increase in blood urea nitrogen levels
  • Increased renal threshold for glucose
  • Weaker bladder muscles with incomplete emptying of
    bladder, tendency for bladder retention
  • Decreased bladder capacity, urinary frequency
  • Reduction of muscle elasticity and tone of supportive
    structures
  • Lower resistance to infection and injury
