Progression For Application Of Hypospadias With TIP Urethroplasty And OIF Urethroplasty

Objective: To evaluate and compare the efficacy of the tubularized incised plate (TIP) urethroplasty and the Onlay island flap (OIF) urethroplasty in hypospadias repair, and approach the choice between the two.Methods: The clinical data of 42 cases of TIP procedures and 26 cases of OIF procedures were analyzed Retrospectively.TIP group were 2-13 years old,with an average age of 4.76,includingⅡtype 3 cases, IV type 1 case,38 were primary surgery,4 were repeat surgery ;OIF group were 2-10 years old, with an average ageof 4.72,includingⅡtype 23 cases,and III type 3 cases,all were primary surgery.Results: In TIP group,80 min with mean duration of surgery, 7cases with urethral fistula, 1 case with neourethral dehiscence,none with urethral stricture ,and 1 case with outside of urethral stricture,3 repeat surgery cases without complications ;In OIF group,115 min with mean duration of surgery,5 cases with urethral fistula,1case with neourethral dehiscence,and none with urethral stricture.There was no statistically significant difference in the incidence of fistula,stricture,dehiscence and success rate of onestage operation between the TIP group and the OIF group (p〉0.05),But there was statistically significant difference in the mean duration of surgery between these two groups (p〈0.05).Conclusions: TIP urethroplasty and OIF urethroplasty can be used in distal and proximal hypospadias, TIP urethroplasty is more simplified than OIF urethroplasty, and more applicable to the primary surgery failed cases;OIF urethroplasty is suitable for the primary surgery patients with poor development of penis and urethral plate.
