Accurate preoperative diagnosis and laparoscopic removal of the cavitated non-communicated uterine horn for obstructive Mullerian anomalies

Obstructive Mullerian anomalies cause severe dysmenorrhea following menarche as a result of disturbed menstrual outflow. Therefore, surgical management such as extirpation of the obstructive uterine horn is required for treatment of these patients. It is necessary to have a detailed understanding of the pathological conditions of the pelvic organs and urinary system prior to surgery. We report three cases of reproductive, nulligravid patients diagnosed as having obstructive Mullerian anomalies. Preoperative accurate diagnosis was obtained by magnetic resonance imaging (MRI) and 3-D computed tomography (CT) angiography. Laparoscopic resection of the rudimentary uterine horn was performed safely and completely, and resolved all problems. MRI and 3-D CT angiography are useful tools for diagnosing complex Mullerian anomalies, and operative laparoscopy may be an alternative treatment for these cases.
