Calyxo, Inc. was founded in February 2016 in collaboration with leading U.S. urologists who recognized the profound need for improved kidney stone treatment. Kidney stone disease is a common problem that is painful and consumes vast amounts of healthcare resources each year. We are focused on delivering innovative solutions to better meet the needs of kidney stone patients and transform the care of this condition.


We are dedicated to improving care for patients with kidney stones by delivering paradigm-shifting solutions that enable urologists to safely, effectively and efficiently achieve unrivaled clinical outcomes.


We envision a day when kidney stones are efficiently removed in a routine, one-time treatment, leaving behind only peace of mind for both patients and physicians.


The kidneys are two bean-shaped organs that filter waste and extra water from the blood to make urine.0Kidney stones form when minerals and*acid salts in the urine turn into hard deposits.0Usually this happens when the levels of minerals and*acid salts in the urine are high and the fluid level is low.0The stones form in the kidney and can cause severe pain as they pass through the urinary tract.0It is estimated that over 27 million Americans have been affected by kidney stones.1,2 Studies have shown that kidney stone disease is more*common among older men but has been increasing lately among women, especially those 20-39 years old.1


The healthcare burden from kidney stone disease is staggering. Kidney stones are among the top 10 reasons for visiting a urologist.3 In 2014, there were over 1.1 million emergency department visits due to kidney stones.4 In 2016, $403 million was spent on inpatient hospital care for this condition.5 Total direct costs of kidney stone treatment in the U.S. are expected to exceed $4.1 billion by 2030.6
