【目的】应用极坐标系建立数字化膀胱，精确标定膀胱内病灶位置。【方法】将适度充盈的膀胱看做近似球形，以尿道内口几何中心为极点，以左右输尿管开口的连线的垂直平分线为极轴建立极坐标系。【结果】以极坐标来标定膀胱内病灶位置，方法简单，位置参数数据直观、方便，定位精度较高，可以满足临床交流及手术定位需要。【结论】应用极坐标系建立数字化膀胱理论上可行，实际应用中方便，具有广阔的应用前景，值得推广。

To establish digital bladder by using polar coordinate system in order to label the lo-cation of bladder lesion accurately .[Methods]With the properly filled bladder as round shape ,internal ure-thral orifice geometrical center as pole and left and right ureteral opening line perpendicular bisector as polar axis ,the polar coordinate system was set up .[Results]The polar coordinate for labeling the location of bladder lesion was a simple method ,and could obtain intuitive ,convenient and high accurate location parameter data , and also met clinical demand for communication and operation location .[Conclusion] Polar coordinate system for establishing digital bladder is feasible in theory and convenient in practice ,and has wide application pros-pect ,so it is worthy of promotion .
