RoboticBuccalMucosalUreteroplastyforUreteralStrictureAfterRoboticUreterolysis2月1日召开的北京市第二十二届清泌会大量讨论了有关泌尿外科手术并发症的种种,颇具深意。念及此处,《柳叶新潮》特针对输尿管术后并发症选文一篇,望各位读者不吝雅正!
INTRODUCTIONANDOBJECTIVES简介与目的

近端输尿管的长狭窄为重建带来了严峻挑战。近期,一种利用颊粘膜(BMG)进行重建的机器人辅助式输尿管成形术问世。我们将介绍一例接受了机器人输尿管松解术,并在随后一年接受机器人输尿管成形术的患者,旨在描述两类机器人技术。

该病例为一名58岁的正在接受垂体肿瘤药物治疗的男性患者,其表现为左输尿管梗阻,该患者在药物治疗失败后,接受了针对可能存在的腹膜后纤维化的机器人输尿管松解术/网膜包囊术。纤维化被分离至扭曲的左髂动脉区域,该现象可能是因先前在心脏手术期间的股动脉导管插入所引发的创伤导致的,输尿管无纤维化附属物,并被网膜包囊所覆盖。该患者在一年内进展状况良好,但最终发展为周期性输尿管梗阻,伴有输尿管上/中段6cm狭窄,需要接受肾造口术导液及支架。该患者选择接受BMG输尿管成形术。在两次机器人手术中,患者取改良式侧卧切石位,与肾盂成形术类似。口腔应在输尿管成形术前为BMG采集做好准备。输尿管镜及近红外荧光被用于界定近端及远端狭窄的程度。狭窄测量完成后,进行相应的BMG采集。通过输尿管镜沿狭窄长度进行输尿管切开术。BGM作为上层补片被缝合至输尿管边缘。利用输尿管镜确认通畅率,并安置支架。将网膜包囊缝合至输尿管及BMG上方,用于血液供给。
