Researchers have demonstrated that both subtotal and total hysterectomy were equally effective in relieving symptoms, and that neither caused adverse effects on the function of other pelvic organs.
Unlike patients who have total hysterectomy, some patients with subtotal hysterectomy continued to have cyclic bleeding, and all required ongoing smear tests.
The researchers have commented that longer follow-up is necessary to determine if pelvic organ prolapse is more common with one procedure compared with the other. Since prolapse may occur years after hysterectomy, long-term follow-up is needed to assess whether retaining the cervix results in better support of the vaginal vault.
