肾移植的受体位置:临床将移植的肾脏放在受体的盆腔内 ,髂窝部是移植肾放置的较理想位置。 do you want to go to a movie book 8 module 5 hopes and fantasies unit 13 work with language jobs Liming meets Jennys classes 肾移植手术吻合血管的选择:将供体肾的肾动脉与受体 髂内动脉及其分支吻接,将肾静脉与髂内静脉吻合(必须将 所有的肾动脉都与受体的动脉吻合,以免发生肾的局部坏死 或供血不良)。 输尿管的吻合位置:将输尿管吻接到膀胱上,使尿液流 入膀胱内。输尿管与膀胱的吻合更须细心谨慎,以防尿液的 渗漏导致局部的感染及败血症等并发症的发生,从而导致手 术失败。 肾移植的病人需在手术后长期服用免疫抑制药物,因此 ,术后对病人其他并发症的预防、治疗和处理也是非常重要 的环节。 do you want to go to a movie book 8 module 5 hopes and fantasies unit 13 work with language jobs Liming meets Jennys classes 第二节 输尿管(Ureter) 起止起止 行程行程 分段分段 狭窄狭窄 输尿管腹部 输尿管盆部 输尿管壁内部 上狭窄 中狭窄 下狭窄 do
