Ecografía pélvica: correlación de la evolución de útero y ovarios con estadios de Tanner de mama y edad

Correlacionar la evolucion ecografica de utero y ovarios, segun los estadios de Tanner de mama y la edad cronologica en pacientes que acudieron a la consulta de ginecologia infantil y juvenil del hospital de ninos “Dr. Jose Manuel de los Rios” entre marzo y octubre de 2016. Metodos: Se evaluaron 113 pacientes con edades entre 7,7 y 15,5 anos, excluyendo aquellas que habian presentado la menarquia, portadoras de malformacion uroginecologica, con antecedente de cirugia uterina u ovarica o diagnostico de alguna endocrinopatia. Se clasificaron segun estadios de Tanner de mama y se les realizo ecografia pelvica transabdominal, se midio y describio utero y ovarios. Se calculo la media, desviacion estandar y mediana segun el tipo de variable, se aplico ANOVA, prueba no parametrica H de Kruskal-Wallis y chi-cuadrado de Pearson, se considero un valor estadisticamente significativo si p < 0,05. Resultados: La longitud uterina vario desde 33 mm en pacientes con Tanner I hasta 52 mm en aquellas con Tanner IV, la relacion cuerpo/cuello fue de 0,9 en pacientes con estadio I; 1,12 en estadio II; 1,42 estadio III y 1,30 estadio IV. Se encontro relacion estadisticamente significativa entre los volumenes ovaricos tanto con los grupos etarios como con los estadios de Tanner. En cuanto al patron ovarico, el mas frecuente observado fue el microfolicular. Conclusiones: El utero y los ovarios presentan crecimiento continuo en relacion a la edad y al estadio de Tanner de mama, factores con los cuales se demostro relacion estadisticamente significativa. To correlate the ultrasound evolution of the uterus and ovaries, according to Tanner’s stages of breast and chronological age in patients attending the children’s and juvenile gynecology clinic of the children’s hospital “Dr. Jose Manuel de los Rios “between March and October 2016. Methods: 113 patients aged between 7.7 and 15.5 years were evaluated. From them were excluded those ones who had presented menarche, urogynecologic malformation, endocrinopathy or a history of uterine or ovarian surgery. They were classified according to Tanner stages of breast. Transabdominal pelvic ultrasound was performed, additionally uterus and ovaries were measured and described. We calculated the mean standard deviation and median according to the type of variable, we applied an ANOVA non-parametric test of Kruskal-Wallis and chi-square of Pearson, it can be considered a statistically significant value if p <0.05. Results: Uterine length ranged from 33 mm in patients with Tanner I up to 52 mm in those with Tanner IV. Body/cervix ratio was 0.9 in patients with stage I, 1.12 with stage II, 1.42 with stage III and 1.30 with stage IV. A statistically significant relationship was found between ovarian volumes with both age groups and Tanner stages. As for the ovarian pattern, the most frequent one was the microfollicular. Conclusions: The uterus and ovaries show continuous growth in relation to age and the Tanner stage of breast, those factors with which a statistically significant relationship was demonstrated.
