The wedge-like partition may involve only the superior part of the cavity resulting in an incomplete septum or a subseptate uterus, or less frequently the total length of the cavity (complete septum) and the cervix resulting in a double cervix.

This process begins caudally and advances cranially, thus a complete septum formation represents an earlier disturbance of this absorption than the incomplete form.

[citation needed] Helpful techniques to investigate a septum are transvaginal ultrasonography and sonohysterography, MRI, and hysteroscopy.

An important category of septate uterus is the hybrid type a variant that may be misdiagnosed as bicornuate uterus when seen by laparoscopy[6] Professor El Saman From Egypt was the first to describe this anomaly and warned gynecologist about this common misdiagnosis, whenever there is a uterine fundus depression on laparoscopy gynecologists should compare the depth of this depression with the depth of the dividing internal interface.

Hysteroscopic removal of a uterine septum is generally the preferred method, as the intervention is relatively minor and safe in experienced hands.

Tactile cold scissor metroplasty was described as a back technique for hysteroscopic challenges that interfere with proper visualization[8] or uterine distention.

[4] In contrast, in about 15% of patients with recurrent pregnancy loss anatomical problems are thought to be causative with the septate uterus as the most common finding.
