The invention belongs to the technical field of flushing devices, and discloses a flushing device for urinary surgery, which comprises a water tank, a water conveying assembly, a water collecting assembly, a drying assembly and a shielding assembly, wherein the water conveying assembly comprises a water conveying part for conveying water out of the water tank, and the water conveying assembly further comprises a tool cleaning part and a wound cleaning part. The hot-air blower is arranged in the through groove formed in the water collecting frame body, so that the drying structure and the flushing part are combined into a whole, other structures do not need to be additionally arranged for enclosing a drying area, the overall size of the flushing device is greatly reduced, in addition, when surgical instruments are cleaned, the baffle is located in the caulking groove and can block at the air outlet front end of the hot-air blower, flushing water can be effectively prevented from being splashed into the hot-air blower, risks such as short circuit are prevented, when drying is needed, the baffle can be driven by the electric telescopic rod to move downwards, the air outlet front end of the hot-air blower can be opened, and hot air can conveniently flow into the hot-air blower.
