title: Blood loss in the space of Retzius and pelvis with tension-free vaginal tape and trans-obturator tape procedures.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the space of Retzius and pelvis for hematoma formation and blood loss following placement of tension-free vaginal tapes (TVT) and transobturator tapes (TOT).
  
  
  METHODS
  25 women were examined with ultrasonography on post-operative days one, two, three, four or five. One patient underwent TVT while the other 24 underwent TOT. Additional procedures were performed on most patients.
  
  
  RESULTS
  No hematomas or collections of free fluid were identified post-operatively.
  
  
  CONCLUSIONS
  TVT and TOT procedures are relatively safe procedures. We encountered no vascular complications in this small series of patients. Review of literature has yielded reports of infrequent complications.
