Abstract:
ObjectiveTo evaluate the effect of inlay buccal mucosa graft with tubularized incised urethral plates (TIP) urethroplasty for hypospadias repair. MethodsFrom January 2005 to December 2010,a total of 343 cases of hypospadias underwent a buccal mucosa graft with TIP urethroplasty.The patients aged from 6 months to 61 years,mean 7 years.One hundred and forty-seven were primary surgery cases,and 196 cases had a history of failed surgery.In primary cases,124 were distal type and 23 were proximal type.There were 137 distal type cases and 59 proximal types in failed case group.A buccal mucosa graft was harvested from lower lip,fixed into the incised urethral plates in primary cases.In re-do cases,open urethral and remove scar tissue were necessary. ResultsThe width of the buccal mucosa ranged 0.5 - 2.5 cm,length ranged 1.0 - 8.5 cm.All the patients were followed up for 6 - 36 months,average 16 months.In primary group,fistula occurred in 14 cases (9.5％ ),and urethral stricture in 2 cases (1.4％),in which 1 proximal case occurred both with urethral stricture and fistula; the overall success rate was 89.8％.In re-do group,fistula occurred in 32 cases ( 16.3％ ),and stricture in 13 cases (6.6％),in which 1 distal and 5 proximal cases occurred with both urethral stricture and fistula; the overall success rate was 80.1％. ConclusionsInlay buccal mucosal graft with TIP technique is an effective instrumentality for hypospadias repair because of its high successful rate,good cosmetic effect and without affecting on oral appearance and function in donor site.
