My understanding is that teas, etc...have a lot of caffeine.
There is probably some truth in that, but heres the scoop:
Foods and Drinks Containing Oxalate
People prone to forming calcium oxalate stones may be asked by their doctor to cut back on certain foods if their urine contains an excess of oxalate:
* beets
* chocolate
* coffee
* cola
* nuts
* rhubarb
* spinach
* strawberries
* tea
* wheat bran
People should not give up or avoid eating these foods without talking to their doctor first. In most cases, these foods can be eaten in limited amounts.
There is no surgical way to remove kidney stones, unfortunately.
Percutaneous Nephrolithotomy
Sometimes a procedure called percutaneous nephrolithotomy is recommended to remove a stone. This treatment is often used when the stone is quite large or in a location that does not allow effective use of ESWL.
Percutaneous nephrolithotomy
In this procedure, the surgeon makes a tiny incision in the back and creates a tunnel directly into the kidney. Using an instrument called a nephroscope, the surgeon locates and removes the stone. For large stones, some type of energy probe (ultrasonic or electrohydraulic) may be needed to break the stone into small pieces. Generally, patients stay in the hospital for several days and may have a small tube called a nephrostomy tube left in the kidney during the healing process.
One advantage of percutaneous nephrolithotomy over ESWL is that the surgeon removes the stone fragments instead of relying on their natural passage from the kidney.
Yuck. Shudder. Hope mine stay small.
