title: [Bacteriology study of hypospadias].
abstract: OBJECTIVE
  This clinical study was to explore why the neo-urethra is liable to be infected after hypospadias operation, find the source and the common floras of infection, and accordingly, improve the peroperation procedures so as to reduce postoperative infection rate.
  
  
  METHODS
  The pathogenic floras were examined and analyzed by germiculture and karyotype analysis.
  
  
  RESULTS
  The bacteria in the neo-urethra mostly came from the orifice and the reconstruction material of the urethra. The most common floras that caused infection were gram-positive coccus. The most sensitive antibiotics for hypospadias infection were demethylvancomycin.
  
  
  CONCLUSIONS
  The postoperative infection of hypospadias is incisional, not the urinary system infection. Because the microenvironment of the neo-urethra is more suitable for infection than that of the skin or mucosa, the reconstructed urethra is likely to be infected.
