Kidney Embryology
Kidney > Pelvis > Ureter > Ureteral Orifice in the Bladder > Prostatic Urethra > Membranous
Urethra > Spongy Urethra > Ext. Urethral Orifice
Kidney removes excessive water and salt from the bloodstream
Kidney disease = higher blood pressure
In the developing child:
approximately 3 week. End of 3rd week, first kidney in the neck (Pronephros Kidney)
Disappear, then the middle pair of kidney form in the chest, formed by the end of 4th week.
Heart start pumping in the 4th week. Then mesonephros disappear
5th week - metanephros in the pelvis
Kidney moves up and stops by an abdominal organ. Right kidney goes up until it hit the mass of
liver. The spleen stops the left kidney from moving up. Right kidney is lower than the left kidney.
Renal Arteries to the right and left kidney. Fat around the kidney to protect it.
Pronephros - in Neck
Mesonephros - in Chest
Meta(last)nephros - in Pelvis
Ectopic (out of place) kidneys
Common
Intravenous Pyelograms (IVPs)
Inject into the veins that dyes. Interlobar arteries and pierce the medulla.
Treatment of Kidney Diseases: Dialysis or Transplant
Kidney is placed in the recipient's pelvis. Kidney is removed and tie off arteries and veins and
ureter. Small incision, hook up the renal artery. PINKS UP, organ needs to pink up or blood clot.
If it does not Pink up then the surgeon need to re plump. Arteries first, veins second, ureter last.
Part of Ureter is use to connect to the urinary bladder, then the rest is discarded.
Smoking may -> Cancer in Kidney and for urinary bladder
If cancer, one kidney needs to be remove. You can live with one kidney
Kidney Stones. Smoking may also damage urinary bladder, lungs, and kidney.
Urinary Tract Infections (UTIs) and Cranberry Juice
Common, common in women. Why? Urethra is shorter. Prevent it by drinking cranberry juice.
Kills e coli.
