title: Treatment of varicocele: a prospective randomized comparison of laparoscopy versus antegrade sclerotherapy.
abstract: OBJECTIVE
  To compare the therapeutic success, the morbidity and the costs of antegrade sclerotherapy versus laparoscopic varicocelectomy.
  
  
  METHODS
  Seventy-six consecutive varicocele patients were randomly assigned to two treatment arms. Preoperative and 3 month postoperative sperm density, motility and morphology were analysed. The diagnosis of the varicocele was established clinically and with Doppler ultrasonography.
  
  
  RESULTS
  Fifty-eight patients treated by either of the two methods were followed up. The recurrence rate increased progressively with the size of the varicocele in both groups. The postoperative incidence of complications particularly hydrocele formation was significantly higher in the laparoscopic group. The costs of the disposable material for laparoscopic varicocelectomy was twice as high as for sclerotherapy.
  
  
  CONCLUSIONS
  Antegrade sclerotherapy is the less invasive treatment method of male varicocele with lower costs and better outcome and should therefore be the preferred treatment method for male varicocele.
