Vaginal length and incidence of dyspareunia after total abdominal versus vaginal hysterectomy

Abstract

Objective To evaluate the vaginal length and incidence of dyspareunia after total abdominal hysterectomy compared to vaginal hysterectomy. Study design This is a prospective observational study. Sixty-six patients were invited to participate in the study who were already planned to undergo abdominal or vaginal hysterectomy for different benign indications in the OB/GYN department, Sohag University Hospital, during the period from March 2007 till April 2009. Patients were classified into two groups. Thirty-six patients who were planned to undergo total abdominal hysterectomy (TAH) represented the first group, and 30 patients who were planned to undergo vaginal hysterectomy (VH) represented the second group. Vaginal length was obtained just before the operation and three times postoperatively. Pre- and post-operative dyspareunia was reported. Results The mean pre-operative and post-operative vaginal lengths in the TAH group were nearly the same (10.5 ± 2.1 cm vs. 10.2 ± 1.8 cm) without statistically significant difference. In the VH group, there was a statistically significant difference between pre- and post-operative vaginal length (10.1 ± 1.9 cm vs. 8.4 ± 1.6 cm). In the TAH group, 2 patients (5%) reported a newly developed post-operative dyspareunia. In VH group, 6 patients (20%) developed dyspareunia after surgery. Conclusion Postoperative dyspareunia is more common after vaginal hysterectomy compared to abdominal hysterectomy. This may be attributed to postoperative shortening of the vagina secondary to excessive trimming of the vaginal walls especially if VH was done for utero-vaginal prolapse.
