Clinical analysis of uterine intravenous leiomyomatosis: A retrospective study of 260 cases.

The use of gonadotrophin releasing hormone agonist (GnRHa) cannot reduce the postsurgical recurrence rate of patients with UIVL. Compared to total hysterectomy and bilateral salpingo-oophorectomy (TH-BSO), total hysterectomy (TH) does not increase the odds of recurrence, but the chance of recurrence with tumorectomy (TE) is 20 times higher than that of TH-BSO.
