OBJECTIVE: Tubularized incised plate (TIP) urethroplasty is performed by many pediatric urologists and has been widely accepted for repair of distal and mid-shaft hypospadias. However, the role of urethral catheter placement in TIP repair remains controversial. In this study, the surgical outcomes of indwelling urethral catheter and non-catheter TIP repairs in boys with hypospadias were compared.

METHODS: A total of 254 patients with primary distal and mid-shaft hypospadias underwent TIP repair and were evaluated retrospectively. A urethral catheter was placed in 103 patients (group A) and non-catheter repair was performed in 151 patients (group B). Information obtained included age, toilet training, chordee, type of hypospadias, presence or absence of a catheter, and postoperative complications. The complications recorded included wound infection, urinary tract infection, bladder spasm, urinary retention, urinary extravasation, meatal stenosis, urethral stricture, and urethrocutaneous fistula.

RESULTS: There was no statistical difference in age, toilet training, chordee, hypospadias site, or performing surgeon between the two groups. The median follow-up time was 22 and 24 months for groups A and B, respectively. The rate of bladder spasms (10.7 vs. 0%, p < 0.001) and urinary tract infection (9.7 vs. 3.3%, p = 0.034) was significantly higher for group A than group B. Although the rate of urinary retention was higher in group B than in group A (4.0 vs. 0%), there was no statistically significant difference between the two groups (p = 0.084). Likewise, the incidence of urethrocutaneous fistula and meatal stenosis was not significantly different.

CONCLUSION: Non-catheter TIP repair is feasible and positive outcomes can be achieved with minimal complications and less patient discomfort.
