title: A novel hysteroscopic hook for extracting retained contraceptive intrauterine devices under direct vision.
abstract: OBJECTIVE
  The study evaluated the efficacy of removing retained intrauterine devices (IUDs) under direct vision using a novel hysteroscopic hook.
  
  
  METHODS
  In a retrospective observational study, 83 patients (group 1) underwent IUD extraction using a hysteroscopic IUD removal hook (HIRH) and 60 patients (group 2) underwent traditional hysteroscopic IUD extraction. We recorded the blood loss, operation time and success rate.
  
  
  RESULTS
  The operation time was shorter (10.7 vs. 17.7 min; p < 0.001) and the success rate higher in group 1 compared with group 2 (odds ratio 1.09; p = 0.027).
  
  
  CONCLUSIONS
  The HIRH is an effective, simple, inexpensive and durable tool for the direct visual removal of IUDs partially embedded in the endometrium and for damaged IUDs.
