OBJECTIVE: To review our preliminary results of tubularized incised-plate (TIP) urethroplasty for reoperative hypospadias repair.

PATIENTS AND METHODS: The study comprised 15 patients, of whom eight had undergone a previous repair by techniques that included incision into the midline of the urethral plate, while in the remaining seven the midline of the plate had been left undisturbed. The meatus at reoperation was subcoronal or on the distal shaft in all but one boy, who had a midshaft hypospadias. All had previously undergone one attempt at hypospadias repair, except for one patient presenting after two failed 'meatal advancement and glanuloplasty incorporated' procedures. The TIP repair was undertaken as described for primary surgery, except that the dorsal dartos flaps for interposition between the neourethra and skin closure were available less often.

RESULTS: TIP resulted in a functional neourethra and a cosmetically normal meatus in 13 of the 15 patients. One boy healed with a slightly rounded meatus and the other had wound dehiscence; fistulae developed in another two boys, giving three patients with complications. The fistulae occurred in boys whose original surgery did not include urethral plate incision, while the dehiscence was in a patient with partial excision of the plate during previous tubularized preputial flap repair.

CONCLUSIONS: TIP urethroplasty can potentially be used for hypospadias reoperation. Previous incision of the urethral plate was not a contraindication in these selected cases in which the plate appeared supple. However, TIP repair should be avoided in repeat hypospadias surgery if the plate has been resected or is obviously scarred.
