【临床表现】尿道下裂的临床表现非常有特点，①尿道开口异位尿道异位开口于从正常尿道口近端至会阴部的任何部位部分尿道口有轻度狭窄因其表面有一层非常薄的黏膜样组织不完全覆盖所致有时尿道的一段海绵体缺如，其壁菲薄尿线一般向后，故患儿常取蹲位排尿，尿道口位于阴茎体近端时更明显阴茎向腹侧弯曲，主要因尿道口远端的尿道板纤维组织增生阴茎腹侧和尿道壁各层组织缺乏以及阴茎海绵体背、腹两侧不对称所致包皮堆积于背侧，阴茎头腹侧包皮未能在中线融合包皮系带缺如，全部包皮转至阴茎背侧，呈帽状堆积尿道口位置尿道下裂分为四型，阴茎头型、阴茎体型、阴茎阴囊型和会阴型（图12-8）。 | [

（一）高未结合胆红素血症引起的原因有：①胆红素产生过多：如母婴血型不合、遗传性球形红细胞增多症、红细胞酶的缺陷（如G-6-PD、丙酮酸激酶、己糖激酶等）、血管外溶血、红细胞增多症等；②肝细胞摄取和结合低下：如肝脏酶系统功能不全引起的黄疸、甲状腺功能低下、进食减少等；③肠-肝循环增加：如胎粪排出延迟等。 | [

ABO血型不合者较Rh不合多见，大多数母亲为O型，子为A或B型，本病可见于第一胎，可能因其母孕前已受其他原因的刺激，如寄生虫感染，注射伤寒疫苗、破伤风或白喉抗毒素等，均可使机体发生初发免疫反应，当怀孕时再次刺激机体产生免疫抗体，即可通过胎盘进入胎儿引起溶血（详见本章第16节）。 | [
