Pelvic ultrasonography in the evaluation of central precocious puberty: comparison with XXXX stimulation test.

@entity3086 @entity53
OBJECTIVE: To compare the ovarian and uterine structure demonstrated sonographically with baseline and @entity3086 -stimulated luteinizing hormone (LH) and @entity53 values in females with suspected precocious puberty. STUDY DESIGN: Retrospective chart review. Fifty females (age 3.1 to 9.5 years) underwent stimulation testing with @entity3086 (20  g/kg) and pelvic ultrasonography. Subjects were grouped as (1) prepubertal (baseline and stimulated LH and @entity53 in prepubertal range); (2) early pubertal (baseline LH and @entity53 in prepubertal range but stimulated LH or @entity53 in pubertal range); and (3) pubertal (baseline and stimulated LH or @entity53 in pubertal range). Sonographic data were compared with baseline and @entity3086 -stimulated LH and @entity53 . RESULTS: Baseline and stimulated LH and stimulated @entity53 significantly correlated with ovarian and uterine volumes. Ovarian and uterine volumes were significantly higher in females in the pubertal group than in females in the prepubertal group. No significant differences were noted in the ovarian or uterine dimensions between the prepubertal and early pubertal groups. There was significant overlap in ovarian and uterine volumes among females in all three groups. CONCLUSION: Contrary to @entity3086 stimulation, pelvic ultrasonography alone cannot distinguish between prepubertal females and those in the early stages of puberty.
