title: Microtubal reanastomosis: success rates as compared to in vitro fertilization.
abstract: OBJECTIVE
  To determine the pregnancy rates of microtubal reanastomosis (MTR) and any associated clinical variables, to determine pregnancy rates and live birth rates of MTR as compared to in vitro fertilization (IVF) and to study the rates of ectopic pregnancy and spontaneous abortion (SAB) after MTR.
  
  
  METHODS
  Retrospective chart review.
  
  
  RESULTS
  At our institution, the pregnancy rate in the first 12 months following MTR was 44.3%. The study also showed that 2 clinical variables of the MTR procedure that had higher pregnancy rates were when Hulka clips (Hulka-Clemens, Richard Wolf, Rosemont, Illinois) or Filshie clips (Coopersurgical, Lake Forest, California) were used as the mechanism of tubal occlusion and if bilateral MTR was performed instead of unilateral. There was not a significant difference in the pregnancy rates of MTR (44.3%) vs. IVF (38%). However, there was a statistically significant difference in the live birth rate of MTR (19%) vs. IVF (31%) (p=0.007). The rates of ectopic pregnancy and SAB after MTR were 10% and 15.7%, respectively.
  
  
  CONCLUSIONS
  This study showed a significantly higher live birth rate when patients underwent IVF as compared to MTR in the first 12 months following an MTR procedure.
