Transvaginal hydro laparoscopy (THL) is a new approach to pelvic anatomic evaluation in the infertile woman. In this procedure a dilating trocar is inserted through the osterior vaginal wall for endoscopic pelvic examination. Normal saline is used to float the bowel out of the pelvis so that one can evaluate the distal Fallopian tubes, ovarian surfaces, pelvic sidewalls, and the cul-de-sac. The THL procedure makes in-office pelvic endoscopy, hysteroscopy, and dye hydrotubation a reality.
