Abstract:

Unicornuate uterus is one of the important types of Müllerian duct developmental abnormalities, referring to a uterine malformation formed by the normal development of only one Müllerian duct. Epidemiological data indicate that the incidence of this malformation in the uterine malformation is 0.3%-4.0%, and about 35% of cases are complicated by a rudimentary uterine horn and ipsilateral renal agenesis. A case of a teenage patient with a non-communicating left rudimentary uterine horn with a cavity and ipsilateral renal agenesis is reported. The clinical manifestation was progressive exacerbation of dysmenorrhea. The diagnosis was confirmed by pelvic magnetic resonance imaging. After excluding surgical contraindications, single-port trans-umbilical laparoscopic resection of the rudimentary uterine horn, left salpingectomy, resection of pelvic endometriotic lesions, pelvic adhesion lysis, and umbilical plastic surgery were performed. Postoperative pathological examination confirmed that the endometrium of the rudimentary uterine horn was in the secretory phase, and the patient′s dysmenorrhea symptoms were relieved. This indicates that early diagnosis and standardized surgical management are of great significance for improving patients′ quality of life.
