Uterine lithiasis, management by hysteroscopy: Case report and literature review.

The presence of calculi inside the uterine cavity is an uncommon finding, with few cases described in the literature. Here, we present a clinical case of a 30-year-old patient with uterine lithiasis. The patient presented with 3 months of evolution, characterized by abdominal pain in the hypogastrium, with a report of transvaginal ultrasound of hematometra with suggestive images of endometrial polyps. For this reason, she was scheduled for hysteroscopy, where three lesions of hard consistency were found, with the largest 1.5 cm. Currently, due to the few cases of uterine lithiasis described, there is no explanation of how the stones are formed in the uterine cavity. The age of the patient in this case report and the absence of predisposing factors for uterine calcifications reported in the literature is striking, which leads us to propose a hypothesis of the origin of uterine lithiasis, which is related to the history of cesarean section and the presence of hematometra, such hematic retention could have predisposed to the development of calculi in this patient. Uterine lithiasis is an extremely rare entity with few published cases; therefore, further studies are necessary.
