Abstract:
Objective:To evaluate the therapeutic efficacy of interposition urethroplasty on glandular hypospadias and severe penile curvature.Methods:A total of 9 cases of congenital glandular hypospadias and 2 cases of congenital severe penile curvature (>30°) treated with the interposition urethroplasty technique in the Shenzhen Children′s Hospital from November 2008 to December 2019 were retrospectively analyzed.The mean age of initial surgery was 40 (25-109) months.Two cases were surgically treated with one-staged interposition urethroplasty and the remaining were treated with two-staged interposition urethroplasty.They were followed up for 8 months to 12 years, including the penile morphology, urination, urethrocutaneous fistula, urethral stricture and uroflowmetry.Continuous variables were presented as ± s deviation, Student′s t-test was used for comparison between groups. Results:The median length of interposition urethra was 3.2 (2.2-4.2) cm.The cosmetic appearance of penis was good without residual chordee, urethral stricture or urethral diverticulum in all patients.Two cases had urethrocutaneous fistula(one-staged repair and two-staged repair were performed in one case respectively), which were successfully repaired by re-operation.The maximum of uroflowmetry in patients at 3 months [(8.3±1.0) mL/s] and 6 months [(6.7±1.9) mL/s] after surgery was significantly lower than that of children in healthy control group [(10.5±3.7) mL/s] ( t=3.221, 3.864, all P<0.05). However, there was no significant difference in 1-year maximum of uroflowmetry postoperatively between surgically treated patients [(10.5±3.7) mL/s] and healthy control group ( P>0.05). Conclusions:Interposition urethroplasty is an effective and safe treatment for glandular hypospadias and/or severe penile curvature in children.
