摘　　要：目的探讨基于3D-slicer软件三维影像重建技术在泌尿外科中的应用价值。方法回顾性分析2019年5月—2021年12月首都医科大学附属北京友谊医院收治的36例泌尿系疾病患者的病例资料,其中男性20例,女性16例;中位年龄53.50(41.75,66.25)岁。其中亲属肾移植供者10例,肾肿瘤患者12例,肾积水患者6例,泌尿系结石患者8例,基于3D-slicer软件对36例患者泌尿系CT进行三维影像模型重构,并对目标组织进行形态学测量。结果本研究构建的10例亲属肾移植供者泌尿系结构模型中,7例供肾为单支动脉,3例存在副肾动脉;12例肿瘤肾三维模型中,4例肾肿瘤位于肾上级(其中2例近腹侧,2例近背侧),5例肾肿瘤位于肾中部(其中2例近腹侧,3例近背侧),另3例位于肾下级近腹侧。肿瘤平均最大径为(27.3±9.63)mm,肿瘤平均体积为(15.89±5.93)cm^(2)。研究亦成功构建了6例肾积水患者和8例泌尿系结石(不合并肾积水)患者的泌尿系三维影像模型。不同患者泌尿系三维重建模型中清晰显示了肾脏实质组织、血管、肾盂、肾盏、输尿管的空间结构。临床医师可基于三维重建模型观察血管、输尿管的管径、空间位置及走形方向,评估肾囊肿、肿瘤、结石等占位的位置、形态、体积、与周围组织的毗邻关系。结论3D-slicer软件平台可辅助临床医师重建泌尿系三维空间构型,值得进一步推广应用。Objective To investigate the application value of three-dimensional image reconstruction technology based on 3D-slicer software in urology.Methods The data of 36 patients with urinary tract diseases admitted to Beijing Friendship Hospital,Capital Medical University from May 2019 to December 2021 were retrospectively analyzed,including 20 males and 16 females;the median age was 53.50(41.75,66.25)years.There were 10 relative kidney transplant donors,12 cases with renal tumors,6 cases with hydronephrosis and 8 patients with urinary calculi.The CT urography data of 36 cases were reconstructed into three-dimensional image models based on 3D-slicer software,and the morphology of the target tissue was measured.Results In the urinary system model of 10 relative kidney transplant donors constructed in this study,the type of donor renal artery was single artery in 7 cases and accessory renal artery in 3 cases;In the three-dimensional model of 12 tumor kidneys,4 tumors were located at the upper part of the kidney(2 near ventral and 2 near dorsal),5 tumors were located at the middle part of the kidney(2 near ventral and 3 near dorsal),and 3 tumors were located at the lower part of the kidney near ventral.The average maximum diameter of the tumors was(27.3±9.63)mm,and the tumor volume was(15.89±5.93)cm^(2).The study also successfully constructed a three-dimensional image model of the urinary system in 6 patients with hydronephrosis and 8 patients with urinary calculi(without hydronephrosis).Three-dimensional model image reconstructed by 3D-slicer software clearly showed the spatial structure of renal parenchyma,blood vessels,renal pelvis,calyces and ureter.The diameter,position and direction of ureters and blood vessels can be observed clearly based on the three-dimensional reconstruction model,and clinicians could also evaluate the location,shape,size and adjacent relationship with surrounding tissues of renal cysts,tumors,stones or other masses.Conclusion 3D-slicer software platform can assist clinicians to reconstruct th
