Sensory nerve injuries after uterosacral lig suspension

Flynn MK et al. AJOG 2006;195: 1869-72. The procedure is done to suspend the prolapsed vaginal apex. 7 of 182 women reviewed developed buttock/posterior thigh pain to the popliteal fossa. 3 women had removal of the suture within 2 days resulting in immediate improvement of the pain and the other 4 were treated conservatively with gradual resolution of the pain. In some of the women, pelvic exam showed exacerbation of the pain pulling on the suture. This is the posterior femoral cutaneous nerve that arises from S2-3 roots.
