title: Giant prostatic utricle associated with proximal hypospadias: repair by mucosa divesting and muscular tunnel obliteration.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the effectiveness of a new approach to repair the giant prostatic utricle (pseudovagina) associated with proximal hypospadias.
  
  
  METHODS
  Three patients with giant prostatic utricle associated with proximal hypospadias sought medical advice in our department from 1998 to 2003. The giant prostatic utricles were repaired using the novel approach of divesting of utricular mucosa followed by muscular tunnel obliteration through the opening of the pseudovagina in the dorsal lithotomy position.
  
  
  RESULTS
  Follow-up ranges from 3 to 8 years. The divesting of the prostatic utricle mucosa was successful, and the pseudovagina muscular tunnel was closed completely in all 3 patients. One patient underwent urethroplasty and another repair of urethrocutaneous fistula at the same setting. The third patient underwent a second-stage urethroplasty separately. On follow-up, both the urethral reconstruction and the pseudovagina repair remained successful in all the patients.
  
  
  CONCLUSIONS
  The technique of the divesting of the prostatic utricle mucosa and closure of the muscular wall is an effective alternative approach for repairing giant prostatic utricles. It is safe and simple. The surgical exposure is very good.
