A Software operation diagram. The 3D renal pelvis model figure was generated after importing CTU images. B Point n was set as the stone site, and Point m was set as the ureter site. C The software generates a green line (stone removal path) and gives the corresponding angle parameters, in which the n–q segment (X, Y):(− 30°, 60°), q–m segment (X, Y):(40°, 9°). D–E Sequentially inputting the above parameters on the space rotating bed
