A practical guide to determine the incision line in the treatment of septate uterus: "Süha-Levent's Sign".

Objective: To evaluate the significance of a new sign in the hysteroscopic incision process of the septate uterus.

Design: This is a prospective case control study.

Design Classification: II-2.

Settings: The study was performed in a research hospital.

Patients: Fourty-seven consecutive cases were operated for septate uterus.

Intervention: Septum incision was performed in all cases with a hysteroscopic resectoscope under laparoscopic supervision.

Measurements And Main Results: Methylene blue 0.25% was injected through a Rubin canula in all cases for the assessment of tubal patency. Following the methylene blue injection, hysteroscopic septum incision was performed.

Conclusion: A line (blue line) on the top of the cavity has been observed in 33 of 47 (70.2%) cases. This line (blue line) can be used for determining the midline especially before hysteroscopic incision of uterine septum and can also shorten the operation time.
