do submucous myoma characteristics affect fertility and menstrual outcomes in patients underwent hysteroscopic myomectomy?

background: submucous myomas may be associated with menorrhagia, infertility and dysmenorrhea. objective: the aim of this study was to determine the long term effects of submucousal myoma resection on menorrhagia and infertility; also to detect whether the type, size, and location of myoma affect the surgical success. materials and methods: .totally 98 women referred to hysteroscopy for symptomatic submucousal fibroids (menorrhagia (n=51) and infertility (n=47)) between 2005- 2010 were enrolled in this historical cohort study pregnancy rates and menstrual improvement rates were compared according to myoma characteristics (size, type and location). results: after a mean postoperative period of 23±10 months in 51 patients with excessive bleeding, 13 had recurrent menorrhagia (25%). in other 38 patients excessive bleeding was improved (75%). the improvement rates by location and myoma type: lower segment 100%, fundus 92%, and corpus 63%; type 0) 70%, type 1) 78%, type 2) 80%. the mean sizes of myoma in recurred and improved patients were 23.33 mm and 29.88 mm respectively. 28 of 47 infertile women spontaneously experienced thirty pregnancies (60%). pregnancy rates according to myoma location and type: lower segment 50%, fundus 57%, and corpus 80%; type 0) 75%, type 1) 62%, type 2) 50%. the mean myoma size in patients who became pregnant was 30.38 mm; in patients who did not conceive was 29.95 mm. conclusion: the myoma characetesitics do not affect improvement rates after hysteroscopic myomectomy in patients with unexplained infertility or excessive uterine bleeding.
