Hypospadias are diagnosed at birth. Counseling of the parents should be performed in detail. Isolated hypospadias has to be differentiated from disorders of sexual development which are mostly associated with cryptorchidism and micropenis. The operation is timed around the first birthday. Preoperative hormonal treatment should be reserved for infants with a small glans penis or for repeat surgery. The most popular method in distal hypospadias repair is preservation of the urethral plate and tubularization with or without midline incision. In proximal cases with severe curvature a two-stage procedure may be preferable. Dripping-stent urinary drainage into a double diaper is the best method in infants. The complication rate after primary distal repair is reported in the literature to be less than 10% and after staged procedures in proximal hypospadias over 25%.
尿道下裂在出生时即可诊断。应详细对患儿父母进行咨询。单纯性尿道下裂必须与性发育障碍相鉴别,后者大多与隐睾症和小阴茎有关。手术时间安排在一岁左右。术前激素治疗应仅用于阴茎头较小的婴儿或再次手术的患儿。远端尿道下裂修复最常用的方法是保留尿道板并进行管状化,可选择或不选择中线切口。对于近端伴有严重阴茎弯曲的病例,两期手术可能更为可取。对婴儿而言,采用滴注支架将尿液引流至双层尿布是最佳方法。文献报道,原发性远端修复术后的并发症发生率低于10%,而近端尿道下裂分期手术后的并发症发生率超过25%。
