a really hard kick
Assuming no trauma, possibly a disorder of the reproductive system, or (less likely) a kidney infection. You should see your gynecologist.
i dont think they would cause kidney failure, but it would cause lots of other problems.
What causes spasms in the front right pelvic area?
Epithelial cells in urine would be a pretty good indicator of an infection, this the pelvic pain. ( Maybe kidney or Bladder)
Transverse
Urinating blood is usually caused by a serious kidney stone - although it is true that other kidney injuries, such as a punch to a kidney, can cause this symptom.
Your kidney fell asleep
In general, no. You can live just fine with one kidney.
urine is normally yellow.
The technical term for a floating kidney is nephroptosis. The nethro- means kidney and the -ptosis means "droop or sag." Most docs would probably just use the informal name. A floating kidney is when a kidney drops down into the pelvic area when a person stands up. This event is called a prolapse, which is a word that means something has slipped or fallen out of place.
I am an anesthesiologist, so I do not possess a subspecialist's knowledge of either the kidney or the spleen. However, based on the medical knowledge I do have, I would say that it would be highly unlikely that a kidney infection would result in an enlarged spleen.
No. That would be impossible, because a kidney infection is caused by bacteria that has to travel up the urinary tract to reach the kidneys. There is no type of massage, not even deep tissue, that would cause this to happen.
