1Guangzhou Women and Children's Medical Center, Affiliated Women and Children's Medical Center of Guangzhou Medical University, Guangzhou, China.
Objective:
To report on the outcomes of primary hypospadias repaired with the Byars two-stage procedure.
Materials And Methods:
Primary hypospadias repairs with the Byars two-stage procedure, between 2009 and 2012, were retrospectively reviewed. Medical charts were reviewed and analyzed. Follow up was at two weeks, three months, six months and one year after surgery. Complications, which included fistula, glans dehiscence, meatal stenosis, urethral stricture, diverticulum, recurrent penile curvature and others, were documented and analyzed.
Results:
One hundred and twenty-eight cases were included in the present study. The median follow up was 30 months (range 13-44 months). All flaps took successfully after the first stage. Overall complication rates were 11.8%. Complications included: seven cases of fistula; five glans dehiscence; two urethral strictures, which developed after fistula repair; and one concealed penis. No recurrent penile curvature was recorded.
Conclusions:
The Byars two-stage procedure is an option for primary hypospadias when the urethral plate is transected. It had an 11.8% complication rate in this present study.
