01 Renal Embryology

  • initiate kidney dev
  • mesonephros also degenerate, except some persists as vas
  • bladder not made from kidney

  • CD: only portion of nephron from ureteric bud

  • metanephric duct form outgrowth, ureteric bud
  • ureteric bud send signal to mesenchyme that sends signal back to ureteric bud
  • interaction has to be normal for kidney dev

Pathology

  • purple: metanephric tissue

  • renal agenesis result

  • junction between ureter (7) and pelvis (6)

  • usually bilateral failure

  • can't rise in abdomen

  • key feature: cancer at dome
