title: Sonohysterography  for the diagnosis of residual trophoblastic tissue.
abstract: OBJECTIVE
  To assess the efficacy, safety, and associated complications of sonohysterography for the diagnosis of residual trophoblastic tissue.
  
  
  METHODS
  We conducted a prospective study of 23 consecutive patients admitted to our ultrasonography unit with clinical and ultrasonographic signs of retained intrauterine tissue.
  
  
  RESULTS
  Twelve patients had hydrosonographic features suggestive of residual trophoblastic tissue (i.e., an intrauterine lesion not detachable from the uterine wall after instillation of saline), whereas in 11 cases the hydrosonographic findings were negative for retained tissue. Blood flow was detected within abnormal intrauterine masses in 4 of 12 patients with trophoblastic tissue, whereas it was not detected in any patient without retained tissue (P = .093). No complications were encountered during the procedure or the postprocedure period. None of the patients had anesthetic complications, perforation of the uterus, fluid overload, or any other surgical complication. All 12 patients underwent hysteroscopic removal of the suspected residual trophoblastic tissue, and histologic confirmation of residual trophoblastic tissue was obtained in all cases.
  
  
  CONCLUSIONS
  Sonohysterography for detection and diagnosis of residual trophoblastic tissue is an accurate and safe procedure. Further studies comparing the efficacy of sonohysterography with that of diagnostic hysteroscopy are warranted.
