: 在医疗技术的飞速发展中，微创技术已成为许多领域的重要突破。“泌尿外科技术”以其高精度、低风险的特点在临床应用中尤为突出。“观看并了解一次完整的尿路结石取石（如经皮肾镜碎石）或前列腺切除等手术的详细过程”，不仅为患者及其家属提供了宝贵的“第一手资料”——让他们更直观地理解治疗流程和术后恢复情况；同时对医学生及年轻医生而言也是学习实践的最佳途径之一——通过观察资深专家的操作手法来提升自己的专业技能水平和技术信心。，接下来我们将以一个典型的案例——“腹腔镜下根治性膀胱切除术+原位新膀胱重建”（以下简称RBC-Neobladder），为大家呈现一场从术前准备到麻醉实施再到具体操作的全方位观摩体验之旅…….. 1.前期评估阶段: 首先介绍病人基本信息以及诊断依据: 该例58岁男性患者出现无痛血样尿液长达6个月之久, 经CTU(计算机断层扫描)检查发现其右侧输尿管上段存在巨大占位数病变; B超引导穿刺活检确诊其为高级别浸润型T2期移行细胞癌 (TCC)，根据美国癌症联合委员会分期系统该病例属于c T3a N0 Mx 期 ，随后进行全面体格检査包括心电图/肺功能测试 /血液学指标检测 等确保无其他严重并发症可耐受手术治疗 . 最后确定治疗方案 : R BC - Ne o b l a d der 是目前公认的金标准治疗方法 , 其目的是完全去除肿瘤组织的同时保留部分尿道括约肌功能和性生活质量 ; 但由于此项复杂程度极高且涉及多器官重建故需由经验丰富团队执行 ..... ...... .................. ..... .... ................................................................. ................ .... 4.术中细节展示环节开始前再次强调无菌原则的重要性, 并简要说明所需器械设备清单 ：消毒液 、手套套件 （含双极电凝器）、超声刀头 及吸引装置 ；此外还有专门用于建立气腹 的Veress针 和Trocar 系统 以及各种规格缝合线等等 …接着进入关键步骤 —— “造瘘口创建 ” 由主操医师使用 Ver ess needle 从脐部下方一横指处刺入腹腔内直至达到预定深度后连接CO_ { } _{ }{}_} _{}{}}气体泵使腹部膨胀形成工作空间 ，然后依次插入 Tro car 以供后续工具进出…当完成这一步时整个视野被清晰扩大便于下一步动作开展起来 ! 此时助手们则忙着调整光源角度\保持画面稳定 \协助传递物品等工作以保证效率最大化! 紧接着是寻找目标区域即患侧肾脏位置并进行游离处理以便于暴露出足够大的范围来进行手术切除活动...\n随着时间推移可以看到屏幕上显示着越来越清晰的解剖结构图象同时也伴随着紧张而有序的操作声音--这正是在考验每一位参与者耐心与技术的时候了!\nafter successfully isolating the affected kidney and ureter from surrounding tissues,\nthe surgeon proceeds with dissection of adjacent vessels such as inferior vena cava ,\nduodenum etc., using ultrasonic scalpel to minimize blood loss while maintaining precise control over each individual vessel.\nas this delicate process unfolds on screen viewers can see how meticulous attention is paid not only towards achieving surgical goals but also preserving vital structures that could impact patient' s quality life post surgery .\neventually reaching point where tumor mass needs removal -- here comes most challenging part involving en bloc resection including bladder wall itself alongwith regional lymph nodes for complete staging purposes which requires high degree accuracy in both identification AND separation techniques used by skilled hands under guidance provided via advanced imaging technologies like intraoperative ultrasound or fluorescence guided navigation systems available nowadays..\nlater stages involve reconstruction phase starting off creating new urinary diversion system either ileal conduit OR orthotopic neo bladders depending upon patients specific circumstances chosen beforehand based upon discussion between team members during preop planning sessions taking into account factors likesize preference lifestyle considerations among others before making final decision regarding best suited option tailored just rightly fit their unique situation without compromising safety nor efficacy outcomes expected out come results achieved through careful execution steps outlined above throughout entire procedure duration ensuring safe transition back home after successful completion all these efforts put together make sure we deliver topnotch care services every single time no matter what type operation performed inside operating room walls !!
