2、年代开始,神经原性膀胱已经成为肠道年代开始,神经原性膀胱已经成为肠道膀胱成形术的相对适应证,而如今主要由于采用间膀胱成形术的相对适应证,而如今主要由于采用间断自家导尿来排空膀胱的方法被广泛接受,神经原断自家导尿来排空膀胱的方法被广泛接受,神经原性膀胱患者成为施行膀胱成形术的最重要人群。性膀胱患者成为施行膀胱成形术的最重要人群。v肠道膀胱成形术在难治性逼尿肌过度活动及低顺应肠道膀胱成形术在难治性逼尿肌过度活动及低顺应性膀胱患者中是一种安全有效的方法,但对难治性性膀胱患者中是一种安全有效的方法,但对难治性间质性膀胱炎患者效果不佳。间质性膀胱炎患者效果不佳。v可控尿流改道和新膀胱已经成为膀胱癌膀胱全
3、切后可控尿流改道和新膀胱已经成为膀胱癌膀胱全切后的一种经典的改道方式,在高危的膀胱癌患者中回的一种经典的改道方式,在高危的膀胱癌患者中回肠膀胱仍是主要的改道方式。肠膀胱仍是主要的改道方式。v 肠道成行手术和新膀胱的目的在于形成一个低压、高容量的肠道成行手术和新膀胱的目的在于形成一个低压、高容量的储尿囊,储尿囊的排空或依靠间断自家导尿储尿囊,储尿囊的排空或依靠间断自家导尿(intermittent catheterization),或排尿反射,或排尿反射(activation of the micturition reflex),或腹压排尿或腹压排尿(straining)。(Case 1、2、3
4、)v 新膀胱的手术方法很多。偶尔情况下,当膀胱癌患者施行较新膀胱的手术方法很多。偶尔情况下,当膀胱癌患者施行较大范围的膀胱部分切除术时可进行膀胱扩大成形。大范围的膀胱部分切除术时可进行膀胱扩大成形。(Case 6)v 当不能通过尿道间断导尿时,带可控的能导尿的输出道的尿当不能通过尿道间断导尿时,带可控的能导尿的输出道的尿流改道方式是一种选择,但有时合并症较明显。施行膀胱扩流改道方式是一种选择,但有时合并症较明显。施行膀胱扩大手术的患者若不能经尿道导尿时也可做可控的输出道。大手术的患者若不能经尿道导尿时也可做可控的输出道。Urodynamic Findings in Orthotopic Ile
