[Clinical study of hysteroscopy combined with laparoscopy in the diagnosis and treatment of unexplained infertility].

Objective

To explore the importance of the diagnosis and treatment value of laparoscopy and hysteroscopy in patients with unexplained infertility.

Methods

A total of 519 cases diagnosed as unexplained infertility, received laparoscopy and hysteroscopy in Peking Union Medical College Hospital from May 2012 to December 2015. The causes of infertility were evaluated, and the subjects were followed up to observe the nature pregnancy rate.

Results

Among 519 unexplained infertility patients, pelvic abnormalities had been explored in 466 (89.8%, 466/519) cases. Pelvic endometriosis combined with adhesions, pelvic adhesion alone, uterine leiomyoma and uterine cavity polyp were 72.4% (376/519), 12.3% (64/519), 3.7% (19/519) and 1.3% (7/519) respectively. The total natural pregnancy rate within the 3 years of follow up was 53.9% (208/386), and the natural pregnancy rate was 29.8% (31/104) in patients aged 35 years and over.

Conclusions

The patients with clinical diagnosis of unexplained infertility should be examined by hysteroscopy and laparoscopy. Under the examination, the causes of infertility could be found more intuitively, and targeted treatment could be carried out to improve the pregnancy rate. The natural pregnancy rate of the elderly patients decrease obviously after operation, and the time of natural trying pregnancy should not be too long.
