Urine is not highly corrosive. It's mostly sterile, dilute salt water
with a bit of urea, and a neutral pH.

....pH is a measure of how acidic or alkaline a fluid is, like blood or
urine. The pH in blood is maintained within the narrow range of 7.35 to
7.45. Your body maintains this narrow range by using buffers -- chemicals
that can switch back and forth between 2 forms, a weak acid or weak base.
The buffers are only temporary "stop gaps" to avoid dramatic changes in
blood pH.
Long-term correction of blood pH requires the kidneys to excrete the acid or
base in urine. For example, when your blood pH is low (acidic), your kidneys
react by excreting more acid in the urine. The urine pH becomes more acidic
until the blood pH returns to normal.

In some cases, checking your urine pH is helpful for identifying body
acid-base imbalances. In other cases, a blood pH test is needed.

Your provider may want to modify your urine pH to help prevent kidney
stones. Acidic urine is associated with xanthine, cystine, uric acid, and
calcium oxalate stones. Alkaline urine is associated with calcium carbonate,
calcium phosphate, and magnesium phosphate stones.

Some medications are more effective in acidic or alkaline environments. For
example, streptomycin, neomycin, and kanamycin are more effective in
treating urinary tract infections when the urine is alkaline.
