title: Management and outcome of patients with combined vaginal septum, bifid uterus, and ipsilateral renal agenesis (Herlyn-Werner-Wunderlich syndrome).
abstract: OBJECTIVE
  Herlyn-Werner-Wunderlich syndrome (HWWS) is a rare müllerian anomaly consisting of uterine didelphy, hemivaginal septum, and ipsilateral renal agenesis. The purpose of this study was to evaluate the natural history and outcome of patients with HWWS.
  
  
  METHODS
  With ethics review board approval, all patients with uterine/vaginal anomalies were reviewed between 1982 and 2004. Patients with cloacal and/or anorectal anomalies were excluded. Presenting symptoms, preoperative investigations, operative management, and long-term follow-up were assessed.
  
  
  RESULTS
  Of 80 patients identified with uterine/vaginal anomalies, 12 had HWWS. Median age at presentation was 13 years. Most patients (11/12) in this series presented with either abdominal pain and/or pelvic masses. Two patients had intra-abdominal abscesses. Seven patients were menstruating at presentation with 4 of these patients having dysmenorrhea. Symptom duration ranged from 0.5 to 12 months. Diagnosis was confirmed by ultrasound (n = 11), computed tomographic scan (n = 3), and/or magnetic resonance imaging (n = 2). Operative management included vaginal septectomy and drainage of the hematocolpos/hematometrocolpos. One patient required salpingectomy for pyosalpinx. Follow-up ultrasounds revealed no recurrent collections. Median follow-up was 3 years (2 months to 16 years). Eleven patients were asymptomatic after treatment. One patient complained of irregular menses.
  
  
  CONCLUSIONS
  This is one of the largest reviews of HWWS in pediatric patients to date. Good long-term outcome occurs after vaginal septectomy. This diagnosis should be suspected in females with a pelvic mass and ipsilateral renal agenesis.
