This report describes a new procedure for laparoscopic treatment of non-communicating rudimentary uterine horn when attached to the contralateral unicornuate uterus by a band of tissue. A retrograde dissection with primary bipolar coagulation and section of the band of tissue enables primary occlusion of the main blood supply. In our opinion, this new approach may prevent bleeding during laparoscopic dissection of the rudimentary horn and may avoid myometrial injury of the resting unicornuate uterus.
