A surgical kit for providing a cryoprotective composition configured to be applied during cryotreatment of a patient includes: a first container containing a predetermined amount or volume of a biodegradable and/or bioerodible fluid agent; and a second container containing a predetermined amount or volume of a non-toxic cryoprotectant agent. The predetermined amount or volume of the of biodegradable and/or bioerodible fluid agent and the predetermined amount or volume of a non-toxic cryoprotectant agent are configured to be mixed together to form the cryoprotective composition in which a therapeutically effective amount of the cryoprotective composition deposited in a body space of the patient in proximity to the cryotreatment remains within at least a portion of the body space for a duration of the cryotreatment and at least a portion of a body tissue proximate to the body space is viable after the cryotreatment.

Cryoprotective compositions, surgical kits, and methods for protection of a surgical site during cryosurgery

A cryoprotective composition configured to be applied during cryotreatment of a patient includes at least one biodegradable and/or bioerodible fluid agent and at least one non-toxic cryoprotectant agent. A therapeutically effective amount of the cryoprotective composition deposited in a body space of the patient in proximity to the cryotreatment remains within at least a portion of the body space for a duration of the cryotreatment. At least a portion of a body tissue proximate to the body space is viable after the cryotreatment. A method of protecting a surgical site during prostate cryosurgery is also provided. The method includes injecting a therapeutically effective amount of the cryoprotective composition into the body space, wherein the body space is a periprostatic space of a patient.
