Abstract
AIMS To compare the short-term complications between Onlay and Duckett urethroplasty and to analyze the various risk factors cause the complications. METHODS The children with hypospadias who underwent treatment with Onlay or Duckett urethroplasty from November 2014 to June 2016 were followed up. The difference in complications between the two groups was analyzed. Moreover, a single-factor ANOVA was performed to analyze the length and curvature of the penis and the length of the urethral defect. RESULTS 40 patients were treated by Duckett, while 54 by Onlay. In comparison to the Onlay group, the Duckett group showed the initial penile length was shorter (P = 0.044), the initial urethral defect (P = 0.024) and after the correction of chordee was longer (P < 0.001), and the initial penile curvature (P < 0.001) and after degloving (P < 0.001) was greater. Furthermore, the incidence of urethra percutaneous fistula (P = 0.041) and urethral stenosis (P < 0.001) in Duckett group was significantly higher. The analysis of risk factors showed that the age at the time of surgery, the initial penile curvature, the initial urethral defect, and the urethral defect after the correction of chordee were not correlated with the complications. The degree of penile curvature after skin degloving and urethra stenosis was significantly correlated (P = 0.019). CONCLUSION The incidence of complications of urethra percutaneous fistula and urethral stenosis after 1 year of Duckett was higher than that by Onlay approach. The greater the curvature of the penis after skin degloving, the more likely the occurrence of urethral stenosis after surgery.
