Objective:
To verify the usefulness and reliability of transvaginal hydrolaparoscopy (THL) as a screening tool for evaluating infertility in women in comparison with conventional diagnostic laparoscopy.
Study Design:
Sixty consecutive women with unexplained primary infertility were prospectively enrolled into the study. After examination of the whole pelvic cavity, tubal patency was evaluated and the uterine cavity studied by hysteroscopy. Immediately after THL, conventional laparoscopy was performed. Main outcome measures were the success rate of accessing the pouch of Douglas, rate of complete examinations, rate of complications and accuracy of THL in comparison with laparoscopy.
Results:
Success rate of accessing the pouch of Douglas and performing THL was 93.3%. The rate of complete evaluation of all the pelvic structures was 76.8%. In studying tubal pathology, 77.8% agreement was found between the two techniques. Diagnosis of endometriosis was correct in 55.5% of patients. Overall, THL results correlated closely with conventional laparoscopic results in 92.86%, but the diagnostic accuracy of THL was 100% in cases of complete pelvic evaluation.
Conclusion:
THL is a feasible, reliable and safe procedure and can be considered an alternative procedure for evaluating infertility in women. In cases of incomplete pelvic evaluation or abnormal findings, conventional laparoscopy is indicated as the second step in the evaluation.
