HAMBURG, Germany, March 17, 2011 /PRNewswire/ -- Around 5-10% of adults in Central and Western Europe suffer from kidney and ureteral stone disease. These solid formations occur when substances that normally dissolve in the urine are separated out and deposited as fine crystals in those organs. Such stones can be found in the renal calyces, renal pelvis and lower urinary tract (ureter, bladder, urethra).
