Snodgrass尿道成形术治疗尿道下裂

目的：探讨Snodgrass术治疗尿道下裂的疗效。方法：回顾性分析2002年2月-2008年8月收治的50例2～12岁尿道下裂患儿行Snodgrass尿道成形术资料,其中远端型8例,阴茎体型26例,阴茎阴囊交界型12例,会阴型4例,其中9例为二期成形。结果：术后随访1～20个月,6例出现尿瘘,3例出现尿道狭窄。尿瘘经再次治疗成功,尿道狭窄经尿道扩张治愈。结论：Snodgrass尿道成形术操作简单,成功率高,是一种安全、有效的术式,适用于大多数小儿尿道下裂病例的治疗,并适合再次手术的病例。     

Snodgrass术治疗小儿尿道下裂的临床分析

目的分析Snodgrass术联合去上皮组织瓣双重覆盖术对尿道下裂的治疗效果。方法根据病史、体格检查确诊尿道下裂40例,均行Snodgrass术联合去上皮组织瓣双重覆盖术,分析治疗效果。结果Snodgrass术联合去上皮组织瓣双重覆术,35例一次手术成功,5例出现尿道瘘,一次手术成功率为87．5％。结论Snodgrass术式成功率高,并发症少,适合阴茎体型、冠状沟型、下弯不严重的阴茎阴囊型尿道下裂。     

Snodgrass术式在尿道下裂并发症治疗中的应用

目的分析Snodgrass手术(尿道板纵切卷管尿道成形术(TIP))在尿道下裂并发症治疗中的效果.方法回顾2006年1月-2012年1月26例尿道下裂再手术中使用Snodgrass手术的效果.结果总体手术成功率为73.08%,使用与不使用去上皮皮瓣覆盖的手术成功率分别为80.00%及63.64%,但差异无统计学意义(P>0.05).结论 Snodgrass手术是治疗尿道下裂并发症可以优先考虑的手术方式.     

Snodgrass手术治疗46例尿道下裂患儿的临床体会

目的：总结Snodgrass手术治疗小儿尿道下裂的手术经验与体会。方法：于2004年12月～2009年8月间,对46例尿道下裂患儿采用Snodgrass方法进行手术治疗,患儿年龄2～16岁,平均5．6岁;其中冠状沟型6例,阴茎体型40例。结果：经1～26个月随访（平均随访21个月）,所有患儿术后阴茎外形满意,有3例患儿术后出现尿瘘,经再次手术修补后治愈。无尿道憩室和尿道狭窄发生。结论：Snodgrass手术治疗小儿尿道下裂手术方法简单,手术成功率高,术后外形美观,适合于不伴有严重阴茎下弯的尿道下裂患儿。     

A modified tubularised incised plate urethroplasty technique and a revised hypospadias algorithm

To simplify and standardize surgical management of hypospadias, a modified tubularised incised plate (TIP) urethroplasty (Snodgrass) technique has been described and a revised hypospadias management algorithm has been formulated. The study aims to evaluate the viability of the described procedure in different types of hypospadias and tests the validity of the algorithm. The modification described is recruitment of penile and glandular skin lateral to the urethral plate to facilitate tubularisation. The algorithm starts with penile degloving with preservation of urethral plate. Snodgrass repair was done in cases with no chordee and where skin chordee resolved by skin take down. Modified Snodgrass repair was done in cases where urethral plate was narrow. Another modification proposed by us is single layer penile skin closure instead of an added dartos flap, which was done in both classical and modified Snodgrass repair. Cases of severe chordee not resolved by skin take down were repaired by transverse preputial island flap (TPIF) and Bracka''s technique. Dorsal plication was not used as an orthoplasty modality. It was possible to repair 68.89% of the cases by Snodgrass repair. These patients either had no chordee or had superficial skin tethering (skin chordee) which resolved on degolving. All these cases were coronal, distal and mid penile hypospadias. Remaining cases were mid, proximal and penoscrotal with true fibrous chordee and were repaired by TPIF or Bracka''s technique. The Snodgrass technique had a fistula rate of 9.67%. Acceptably, low fistula rate and simple execution make the proposed modification of classical Snodgrass repair a viable option. The proposed algorithm proves to be a useful tool for standardised and logical preoperative decision making. It also defines indications of the three techniques vis-à-vis the type of hypospadias.
