Transvesical port refers to the method of accessing the abdominal cavity through a natural orifice (i.e., urethra) under endoscopic visualization. Since its introduction in 2006, various reports have been published describing different surgical interventions using a rigid ureteroscope in a porcine model. The aim of this study was to test the access and feasibility of peritoneoscopy by using a rigid ureteroscope in a human male cadaver.
Two adult male cadavers were used to perform the procedures. A rigid ureteroscope was used for the creation of transvesical access into the peritoneal cavity. Peritoneoscopy, liver biopsy, and identification and manipulation of the ileocecal appendix were performed.
Transvesical access into the peritoneal cavity was quickly established. The rigid ureteroscope easily allowed visualization of the abdominal cavity with good image quality. Liver biopsy and manipulation of ileocecal appendix were carried out without difficulties.
Peritoneoscopy, liver biopsy, and ileocecal appendix manipulation using a rigid ureteroscope through a transvesical port is feasible in a cadaver model. The development of a specific rigid scope for the transvesical port might herald a promising future for this NOTES access.
经膀胱入路是指在内镜可视化下通过自然孔道（即尿道）进入腹腔的方法。自 2006 年引入以来，已有各种报道描述了在猪模型中使用硬性输尿管镜进行的不同手术干预。本研究旨在使用硬性输尿管镜在男性人体尸体上测试经膀胱入路的进入和可行性。
使用 2 具成年男性尸体进行操作。使用硬性输尿管镜经膀胱入路进入腹膜腔。进行了腹腔镜检查、肝活检以及回盲部阑尾的识别和操作。
快速建立了经膀胱进入腹膜腔的通道。硬性输尿管镜可轻松观察到具有良好图像质量的腹腔。肝活检和回盲部阑尾操作没有困难。
在尸体模型中，使用硬性输尿管镜经膀胱入路进行腹腔镜检查、肝活检和回盲部阑尾操作是可行的。用于经膀胱入路的特定硬性内镜的开发可能预示着这种NOTES 入路的美好未来。
