The invention discloses a calculus collecting device for the urinary surgery, which comprises a containing cylinder, the containing cylinder is of a vertically-through hollow cylinder structure, and a top cover is arranged at the upper end of the containing cylinder; the bottom of the containing cylinder is detachably connected with a base plate, a plurality of filter cylinders are evenly arranged at the bottom of the base plate in the circumferential direction, the inner wall of the containing cylinder is fixedly connected with a urine receiving plate, the bottom of the urine receiving plate is an arc bottom with the lower middle and the higher periphery, leakage holes are formed in the middle of the arc bottom, and a drainage plate is arranged below the urine receiving plate. A drainage hole is eccentrically formed in the drainage disc, the position of the drainage hole is low, the surrounding position of the drainage hole is high, and urine falling from the leakage hole can be drained to the drainage hole. The calculus collecting device has the beneficial effects that the calculus collecting device can collect calculus for multiple times and store the calculus, comparison, observation and analysis are facilitated, and the illness state development trend of a patient can be judged; and the device is convenient to disassemble, assemble, disinfect and clean.
