Tubal patency: hysterosalpingography compared with laparoscopy

Area of Science:

• Reproductive medicine
• Gynecological imaging
• Minimally invasive surgery

Background:

• Infertility affects a significant portion of the population.
• Accurate diagnosis of tubal factors is crucial for successful infertility treatment.
• Hysterosalpingography (HSG) is a common initial imaging test, but its accuracy can be limited.

Purpose of the Study:

• To compare the diagnostic accuracy of hysterosalpingography (HSG) with laparoscopy in evaluating female infertility.
• To determine the rates of false-negative and false-positive results for tubal obstruction using HSG compared to laparoscopy.

Main Methods:

• A prospective study involving 121 infertile patients.
• Hysterosalpingography (HSG) was performed, followed by laparoscopy approximately three months later.
• Comparison of findings related to tubal patency and other pelvic pathologies.

Main Results:

• Normal tubal patency was confirmed in 71 patients (58.6%) by both methods.
• HSG demonstrated a 19% false-negative rate for tubal disease (23 cases).
• HSG showed a 7.4% false-positive rate for tubal obstructions (9 cases).
• Laparoscopy identified additional conditions like endometriosis (31 cases), polycystic ovaries (6 cases), and uterine fibroids (5 cases).

Conclusions:

• Laparoscopy is a more definitive diagnostic tool for evaluating tubal patency and pelvic pathologies in infertile patients.
• HSG has notable false-negative and false-positive rates, potentially impacting treatment decisions.
• Laparoscopy provides a comprehensive assessment, revealing other contributing factors to infertility.
