BACKGROUND
The aim of this study was to describe the surgical approach to, and evaluate the reproductive outcome of, a T-shaped uterus.

METHODS
The study included 97 women who were eligible for hysteroscopic surgery, by either monopolar or bipolar electrosurgical instruments. All had diagnostic hysteroscopy 2 months afterwards to assess the success of the procedure and determine whether any synechiae were present.

RESULTS
Forty-eight women (49.5%) became pregnant after metroplasty. The overall live birth rate per pregnancy before surgery was 0%; for these patients, it increased to 73%, and their miscarriage rate fell from 78 to 27% (P < 0.05). For all 57 pregnancies in 48 women, the ectopic pregnancy rate was 9% (n = 5), the miscarriage rate 28% (n = 16), the preterm delivery rate 14% (n = 8), the term delivery rate 49% (n = 28) and the live birth rate was 63% (n = 36).

CONCLUSIONS
Hysteroscopic metroplasty improves the live birth rate for women with a T-shaped uterus and a history of primary infertility, recurrent abortion or preterm delivery, although it is not a treatment of infertility.

Discussion

A T-shaped uterus can be a primary or congenital malformation (related to DES exposure or other causes) or can be acquired due to marginal adhesions with a T-shaped appearance. The description of the surgical technique and the results of this series are important regardless of the cause of the anomaly.

Two-third of our cases had history of DES exposure, and the results of this series are encouraging for all malformations requiring modification of the cavity volume. The question of systematic cervical cerclage during pregnancy after metroplasty remains open.
