OBJECTIVE: To characterize the anatomical features and clinical settings of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and correlate them with patterns of uterine involvement.
METHODS: Pelvic magnetic resonance images and medical records of 92 MRKH patients were retrospectively reviewed. Patients were subgrouped by uterine morphology: uterine agenesis, unilateral rudimentary uterus and bilateral rudimentary uteri. Uterine volume, presence of endometrium, location of ovary, endometriosis and pelvic pain were compared among groups.
RESULTS: The mean uterine volume was 33.5 ml (17.5-90.0 ml) for unilateral uterine remnants, and 16.1 ml (3.5-21.5 ml) for bilateral uterine rudiments (p<0.01). The incidence of presence of endometrium (100% vs. 22%, p<0.001), haematometra (56% vs. 3%, p<0.001) and ovarian endometriosis (22% vs. 3%, p<0.01) was significantly increased in the group of unilateral rudimentary uteri as compared with the group of bilateral uterine remnants. Thirty-one patients (38%) showed ectopic ovaries. Pelvic pain was more common in individuals with unilateral rudimentary uterus than those who had no (56% vs. 5%, p<0.01) or bilateral uterine remnants (56% vs. 14%, p<0.05).
CONCLUSION: MRKH patients with different patterns of uterine involvement may have differentiated anatomical features and clinical settings.
KEY POINTS: • Rudimentary uteri, especially bilateral rudimentary uteri, were quite common in MRKH syndrome. • Uterine remnants can be relatively large, especially the unilateral rudimentary uterus. • Presence of endometrium and related complications are not rare in MRKH syndrome. • Existence of endometrium and complications are more frequent in unilateral rudimentary uterus.
