To assess the efficiency of transvaginal ultrasonography (TVUS) in the
screening of pelvic pathologies in the initial workup of infertile women,
we carried out a prospective comparison of sonographic diagnosis with
laparoscopic and pathological findings. Between February 1994 and April
1995, 133 premenopausal non-pregnant women underwent TVUS on the day before
laparoscopy. The efficiency of TVUS in detecting pelvic pathologies was
90.2% with a sensitivity of 86.2%, a specificity of 97.8% and positive and
negative predictive values of 98.6 and 78.8% respectively. If the six
false-negative cases with a histological diagnosis of minimal endometriosis
were defined as 'normal pelvis', sensitivity and specificity could be
corrected to 92.5 and 98.6% respectively. Endometriomas were diagnosed by
TVUS with an efficiency of 96.4%, with a sensitivity and a specificity of
90 and 96.7 % and with positive and negative predictive values of 75 and
99.1% respectively. The sensitivity of vaginal sonographic characterization
of pelvic adhesions was 61.1% with a specificity and positive predictive
value of 98.2 and 84.6%. The negative predictive value of TVUS was 94.1%.
These data suggest that it is not possible to characterize pelvic
adhesions, especially filmy adhesions, with acceptable accuracy. However,
in the initial workup of infertile women, if the patient is young, if both
hysterosalpingography and TVUS are negative, laparoscopy could be
postponed. In couples with severe male factor infertility and for whom
in-vitro fertilization or intracytoplasmic sperm injection is the treatment
of choice, laparoscopy might be avoided where the TVUS is negative.
