Ultrasonic evaluation of congenital vaginal oblique septum syndrome: A study of 21 cases

Abstract

The aim of the present study was to investigate the ultrasound features and classify the lesion types of congenital vaginal oblique septum syndrome (CVOS) in 21 patients prior to surgery. Grey-scale pelvic ultrasound was performed to evaluate the uterus, vagina and kidneys in 21 patients with suspected CVOS. Ultrasound features, including the presence of a double uterus, hematocolpos masses and renal absence, in CVOS types I, II and III were studied and compared with intra-operative results and the results of surgery. Ultrasound identified the presence of double uteruses and cervices with ipsilateral renal agenesis on the oblique septum side in all 21 patients. There were 14 hematocolpos lesions on the right and 7 on the left of the vagina. Type I CVOS was diagnosed in 15 patients with a large hematocolpos mass (volume, 64-268 ml) and these diagnoses were confirmed by surgery. Furthermore, there were 4 patients with type II and 2 patients with type III CVOS exhibiting small hematocolpos lesions (volume, 5-36 ml) identified by ultrasound, which were all confirmed by surgery. Therefore, ultrasound imaging is useful tool to evaluate the abnormal features of CVOS and determine the type of CVOS in patients prior to surgical intervention.

Robert's uterus with adenomyosis: A case report and review of the literature

“…Vaginal oblique septum syndrome is often accompanied by developmental abnormalities of the ipsilateral urinary system, mainly a double uterine body, double cervix, and absent kidney on the oblique septum, which can be divided into type 1 perforated oblique septum, type 2 perforated oblique septum, and type 3 perforated oblique septum combined with cervical fistula [8]. The differential diagnosis can be made with the help of gynecologic examination, color ultrasound, HSG, magnetic resonance imaging (MRI), uterine laparoscopy, and other examinations [6,7]. At present, ultrasound is widely used in the diagnosis of uterine malformations, especially three-dimensional ultrasound diagnosis value is higher, can clearly show whether the internal structure and external shape of the uterine cavity is abnormal.…”

Diverse ultrasound image features of unilateral genital tract obstruction with ipsilateral renal anomaly syndrome on genitourinary system segmental sequential ultrasound screening and the accuracy of ultrasonic diagnosis

“…However, owing to an incomplete understanding of the diverse ultrasonic features of this complex syndrome, many ultrasound clinicians misdiagnose or delay the diagnosis of UGTOIRA syndrome. Thus far, the literature on the ultrasonic characteristics of UGTOIRA syndrome has been limited to case reports or small series ( 16 , 17 ).…”
