单纯尿管引流与管中管引流在幼儿尿道成形术中的疗效比较

目的:比较尿道下裂术后单纯硅胶尿管引流与管中管法引流两种引流方法的优缺点。方法:回顾性总结2009年3月至2013年9月361例行尿道成形术尿道下裂患者的临床资料,其中91例采用尿管引流(A组)尿液,270例采用管中管引流(B组)尿液。比较两组患者术后膀胱刺激征、尿瘘、尿道狭窄及尿道憩室发生率。结果:A组发生膀胱刺激征9例(9.89%),尿瘘19例(20.80%),尿道狭窄10例(10.90%),尿道憩室1例(1.09%)。B组发生膀胱刺激征29例(10.70%),尿瘘36例(13.30%),尿道狭窄15例(5.55%),尿道憩室6例(2.22%)。两组膀胱刺激征及尿道憩室发生率并无统计学差别(P0.05),尿管引流组尿瘘发生率高于管中管引流组(P0.05)。尿管引流组尿道狭窄发生率高于管中管引流组(P0.05)。结论:管中管法置管方式并不复杂,疗效优于单纯尿管引流法,值得进一步推广。

Foley catheter versus urethral stent plus gastric tube for urine drainage following urethroplasty

Objective： To compare the advantages and disadvantages of the Foley catheter draining method versus the urethral stent plus gastric tube draining method for urine drainage following urethroplasty for hypospadias. Methods： We retrospectively ana- lyzed the clinical data of 361 cases of hypospadias treated by urethroplasty. After operation, 91 of the cases received urine drainage with the Foley catheter （ group A） and 270 with a urethral stent plus a gastric tube （ group B）. We compared the incidence rates of bladder irritation, fistula, urethral stricture, and urethral diverticulum between the two groups of patients. Results ： No statistically significant differences were found between groups A and B in the incidences of bladder irritation （9.89% vs 10.70%, P 〉 0.05） and urethral diverticulum （ 1.09% vs 2.22% , P 〉 0. 05 ）. The incidence rate of fistula was markedly higher in group A than in B （20.80% vs 13.30%, P〈0.05）, and so was that of urethral stricture （10.90% vs5.55%, P〈0. 05）. Conclusion： The urethral stent plus gastric tube draining method is more effective than the Foley catheter draining method for urine drainage following urethro- plasty.
