urease inhibitors
compounds that inhibit or block the activity of urease, most commonly used in the management of struvite urolithiasis. See also acetohydroxamic acid.
urease tests
a biochemical test used in the identification of some bacteria such as Proteus spp. Using urea agar or broth, bacteria producing urease will cause the formation of ammonia, which is detected by phenol red in the medium.
