Use "calculous" in a sentence
"Medical examination carried out at the end of June - beginning of July 2009 revealed gallbladder stones and pancreatitis and calculous cholecystitis were diagnosed."
"And when such persons make water, the stone forced down by the urine falls into the neck of the bladder and stops the urine, and occasions intense pain; so that calculous children rub their privy parts and tear at them, as supposing that the obstruction to the urine is situated there."
"The real test should always be “is the life meaningful” - its the same calculous we apply when we say giving mice cancer to test cosmetics is ok, but euthanizing retarded children is not."
