Middle Hypospadias, Tabularized incised plate (TIP), Transverse preputial island flap repair (TPIF)


Objectives: To compare the results of Middle Type Hypospadias repair by Tubularized incised plate (TIP) and Transverse preputial island flap (TPIF) in Maharaj Nakorn Chiangmai Hospital.

Methods: Retrospective chart reviewed from 2003 to 2008, 80 patients who underwent middle hypospadias repair were evaluated. Thirty-six patients (45%), underwent Tubularized incised plate urethroplasty (TIP) and 44 patients (55%), underwent Transverse preputial island flap urethroplasty (TPIF). The success rates were compared according to the surgical technique, age, presence of chordee and catheter time.

Results: The presence of chordee was found in 36patients (45%). The success rates of TIP and TPIF were 45.10% and 45.90% respectively, P=1.000. No statistically significant difference was found in patient age, the presence or absence of chordee, catheter time and overall complication. The operative time was statistically significant difference in between both techniques (TIP Mean 2.44+0.10 hrs and TPIF Mean 3.05+0.12 hrs, P=0.0001).

Conclusion: The success rate of middle type hypospadias repair showed no difference in TIP and TPIF technique. But the operative time for TPIF was longer than TIP urethroplasty.
