  • ANY pregnant female since
    • 2 patients
    • can lead to premature labor
    • low birth-weight babies

  • Extrinsic compression of ureter/bladder
  • Immune suppression conditions (diabetes)

A

production of gas in nephric and perinephric area

*almost exclusively in diabetic pts

20
Q

What happens in xanthogranulomatous pyelonephritis?

A

suppurative destruction of renal tissue

can lead to abscess formation

21
Q

What is sepsis? what is septic shock?

A
  1. Suspected or documented infection and an acute increase in organ failure
    1. Dysregulated host response to infection
  2. Progressive organ dysfunction leading to marked increase in mortality
