Kidney Stones complications
back to top
Complications could include:
UTIs are usually caused by bacteria and can occur in any part of the urinary tract. Symptoms of upper UTIs include pain in the upper back, chills, fever, and nausea.
Bacteria that enter the urethra are usually flushed out through urination. However, bacteria that aren't expelled out of the urethra can cause an infection.
Your body becomes overloaded with toxins if your kidneys can't do their regular job. This can lead to kidney failure and even be life-threatening.
A blood urea nitrogen (BUN) test checks kidney function by measuring how much urea nitrogen is in your blood.
