Abstract

Background: Several preoperative factors affect the outcome of Tabularized Incised Plate (TIP) repair. Our aim was to collect and analyze all these factors to define what the most important predictive factors are. Methods: Hundred patients (1–5 years old) with primary distal hypospadias were included. Exclusion criteria included previous penile operations and hormonal treatment or associated congenital anomalies. Anogenital distance (AGD), stretched penile length (SPL), meatal site, glanular shape, chordee and torsion degree, plate width and glans meatus shaft (GMS) score were assessed. TIP repair was done to all patients and followed up for one year. The outcome was correlated with the above parameters. Results: Mean ± SD of age of patients was 3.5 ± 1.5 years, while weight was 14.1 ± 3.0 kg. Complication rate was 18% including urethrocutaneous fistula (UCF) and meatal stenosis 14%, repair breakdown 1% and urethral stricture 3%. Patients with chordee degree < 30° and distal penile meatal location were associated with increased risk for complications by 11.6 and 8.2 times; 95% CI was (1.46–91.75) and (1.02–66.52), respectively (p < 0.05 for each). Plate width ≥ 9 mm, AGD > 5 cm, GMS score ≤ 7 (p < 0.001 for each), age of patient ≤ 2 years old, and SPL > 3.5 cm (p < 0.01 for each) were associated with successful outcome of repair. Conclusion: The proposed successful criteria of TIP repair were absent chordee, coronal/subcoronal penile meatal location, plate width ≥ 9 mm, AGD > 5 cm, age of patient ≤ 2 years old, GMS score ≤ 7, SPL > 3.5 cm and grooved glanular shape.
