Transcervical resection of endometrium (TCRE) has been used as one of the methods for treating abnormal utterine bleeding (AUB), but what is the hemodynamic change in the uterus after TCRE has rarely been reported in the world. Our purpose was to study the uterine hemodynamic changes after TCRE, to find out the mechanism and to improve the further treatment after TCRE. The examinations were performed using Philips ATL3000 ultrasound scanner with a transvaginal 9.0–5.0MHz transducer and a hysteroscope (Germany-Olympus) for surgery. Thirty-five patients with AUB underwent TCRE, which were followed by ultrasonography for one year. We compared the difference of the uterine hemodynamics between the normal control (C) and the AUB study (S) groups before operation and observed the changes after TCRE. Before operation, significant differences of RI, PI, and S/D in the spiral arteries were found between the S-group and the C-group. After TCRE, the RI, PI, and S/D showed significant variance in the repaired layer arteries (RLA), which reached to the level of the normal C-group in the early preliferative phase one year later. Before and after TCRE there were no differences of RI, PI, and S/D in the uterine, arcuate and radial arteries between the normal C-group and S-group. The difference of the uterine hemodynamics in the S-group was only in the RLA, which reached to the level of the normal C-group in the early proliferative phase one year later after TCRE. The mechanism is that the continuously proliferated thickened arteries will lead the periodical hormone treatment to be ineffective to make the arteries atrophied and broken as in the normal arteries, which may be the cause of the ineffectiveness of medicine treatment.
